Description

  The present invention relates to a lamp, a lighting device, and a lighting control device.

  DESCRIPTION OF RELATED ART Conventionally, the illuminating lamp which can be connected as it is to the inverter ballast (in a broad sense, lamp) which lights a fluorescent lamp, and can perform lighting operation is known. As such an illuminating lamp, the illuminating lamp using semiconductor light-emitting devices, such as LED (Light Emitting Diode) illuminating lamp, is mentioned.

  LED lamps have higher luminous efficiency than fluorescent lamps, so they can produce the same brightness as fluorescent lamps with less power consumption than fluorescent lamps. However, when the LED lamp is connected to the lamp as it is and the lighting operation is performed, the lamp supplies the same power as the case where the fluorescent lamp is connected to the LED lamp, so in the LED load of the LED lamp Power consumption more than necessary is generated.

  For this reason, in such an LED lamp (so-called construction-less LED lamp), there is known a technique for generating reactive power in the LED lamp by connecting an inductance to the LED load to save power. (For example, patent documents 1-2).

  However, in the prior art as described above, since an inductance is used to generate reactive power, when an abnormal operation such as power interruption occurs while energy is stored in the inductance, the back electromotive force (high voltage ), Which may destroy the lamp connecting the lamp.

  In addition, LED lighting may be connected to a glow ballast other than an inverter ballast or to a rapid ballast, or it may be connected directly to a commercial AC power supply without the intervention of a ballast (fluorescent ballast). It is desirable to selectively implement appropriate lighting control depending on the presence or absence of the device and the type of ballast.

  Furthermore, since the LED lamp has a long life with respect to the fluorescent lamp, it is also conceivable that the lamp changes in the use cycle as a product. For example, it is a case where it is diverted to the illumination in another room. In such a case, it is necessary to reselect the lighting control selected according to the presence or absence of the ballast and the type of ballast. It is also conceivable that, due to the long life of the LED lamps, the operating characteristics of the ballast may change over time and the selected lighting condition may not be optimal.

  Therefore, the present invention can perform appropriate lighting control according to the lamp, and can perform appropriate lighting control even when the lamp changes or the operation characteristic of the ballast changes. It aims at providing a lighting.

  In order to achieve such an object, a lamp according to the present invention includes rectifying means for full-wave rectifying an AC signal, and two or more lighting means, and the above-mentioned 2 according to the AC signal input from the rectifying means. Lighting control means for selecting one of the lighting means among the above lighting means, light emitting means controlled to emit light by the lighting means selected by the lighting control means, and the lighting means selected by the lighting control means Reset means for resetting the output signal, wherein the reset means detects the presence or absence of the output signal from the rectifying means, and detects the switching time of the presence or absence of the output signal, and detects the pattern of the output signal. Is detected, and the lighting control means is made to reset the lighting means when the pattern satisfies a predetermined condition.

  According to the present invention, appropriate lighting control can be performed according to the lamp, and appropriate lighting control can be performed even when the lamp changes or when the operation characteristic of the ballast changes. it can.

  Hereinafter, the configuration according to the present invention will be described in detail based on the embodiments shown in FIG. 1 to FIG.

(Lighting device)
First, the configuration of the lighting apparatus will be described with reference to FIGS. 1 to 7. FIG. 1 is an external perspective view of a lighting device 300. FIG. As shown in FIG. 1, the lighting device 300 includes a lamp 100 and a lamp 200 on which the lamp 100 is mounted.

  The illuminating lamp 100 includes cap members 1 a and 1 b, a housing 2, and a light transmitting member 3. The housing 2 has an elongated shape made by extruding a metal member such as, for example, an aluminum alloy or a magnesium alloy. In addition, the housing 2 is formed to have a substantially semi-cylindrical cross section. The translucent member 3 has a substantially semi-cylindrical shape which is long like the casing 2 so that the whole becomes substantially cylindrical by being combined with the casing 2. The light transmitting member 3 is formed of resin or glass so as to transmit light beams emitted from a plurality of LEDs described later.

  The cap members 1 a and 1 b have a bottomed cylindrical shape, and function as caps for both ends of the housing 2 and the light transmitting member 3. In addition, the cap members 1 a and 1 b are attached to the sockets 201 a and 201 b of the lamp 200 to thereby physically and electrically connect the lamp 200 and the lamp 100. In this example, the housing 2 has a substantially semi-cylindrical shape, but it is not necessary to limit the casing 2 to a substantially semi-cylindrical shape. In FIG. 1, the light transmitting member 3 is drawn in a semicircular shape, but the cross section may be cylindrical like a fluorescent lamp, and the light transmitting member 3 may be configured to wrap the housing 2.

  FIG. 2 is a cross-sectional view of the lamp 200 taken along the longitudinal direction. As shown in FIG. 2, the lamp 200 has a fluorescent lamp ballast 203 and sockets 201a and 201b for detachably mounting the lamp 100, and is configured to be connectable to a commercial power source E. The frequency of the commercial power source E is, for example, 50 Hz or 60 Hz. Power from the commercial power source E is supplied to the fluorescent lamp ballast 203. As shown in FIG. 2, in the lamp 200, the opposite side of the sockets 201a and 201b is embedded in, for example, a ceiling, and the sockets 201a and 201b are released. The sockets 201 a and 201 b are connected to the fluorescent lamp ballast 203 via the pair of electrode terminals 202 a and 202 b and the wiring 204.

  The fluorescent lamp ballast 203 includes, for example, a fluorescent lamp inverter ballast, a fluorescent lamp glow ballast, and a fluorescent lamp rapid ballast. The fluorescent lamp ballast 203 has a function of generating a signal for lighting the lamp 100, adjusts the frequency and output power according to the type of lamp 100, and operates so that the lamp 100 is stably lit. Do.

  However, the lamp 100 is configured to be directly connectable to a commercial AC power supply, in which case the fluorescent lamp ballast 203 is not necessary. As described above, the lamp 100 can be configured to be connectable to any of a fluorescent lamp glow ballast, a fluorescent lamp rapid ballast, a fluorescent lamp inverter ballast, and a commercial AC power supply.

  3 and 5 are exploded perspective views near the end on the left side of the lamp 100 in the longitudinal direction, and FIGS. 4 and 6 are views near the end on the right side in the longitudinal direction of the lamp 100. It is a disassembled perspective view. FIG. 7 is a cross-sectional view of the lamp 100. However, in FIG. 3, the illustration of the mounting substrate 11a disposed on the upper side of the power supply substrate 7 is omitted, and in FIG. 5, the mounting substrate 11a is illustrated. Similarly, in FIG. 4, the mounting substrate 11 b is omitted, and in FIG. 6, the mounting substrate 11 b is illustrated.

  As shown in FIGS. 3 and 4, the cap members 1a and 1b are fixed to the housing 2 by a plurality of screws 5a, 5b, 5c and 5d. Thus, the cap members 1a and 1b are encased so that the casing 2 and the light transmitting member 3 fitted thereto are integrated. That is, the cap members 1 a and 1 b are provided to cover the both ends of the housing 2 and the light transmitting member 3.

  The cap members 1a and 1b may not be screwed, but may be manufactured by tightly connecting (sealing) a joint with the housing 2 with a tool or the like, or may be insert-molded. The shapes of the cap members 1a and 1b are substantially the same as the shape of the cap members (bases) located at both ends of the existing fluorescent lamp. The lamp 100 is easily replaceable in place of the existing fluorescent lamp attached to the lamp 200.

  As shown in FIGS. 3 to 6, the terminals 4a and 4b are on one cap member 1a, and the electrode terminals 4c and 4d are on the other cap member 1b, respectively, along the longitudinal direction from the cap member 1a or the cap member 1b. It is provided to project. When the electrode terminals 4a, 4b, 4c, 4d are provided for each cap member 1a or cap member 1b, a fixing method such as insert molding, caulking, screw fastening or the like can be used. The illuminating lamp 100 takes in the AC power from the commercial power source E via the lamp 200, the connector 16 and the like disposed in the respective cap members 1a and 1b. The AC power taken in is fed to the power supply substrate 7 shown in FIG. 3 through the lead wires 6a, 6b, 6c, 6d.

  The power supply substrate 7 is provided with an electronic component 9 for DC power conversion for converting the obtained AC power into DC power and supplying the DC power to the mounting substrates 11a and 11b. As shown in FIGS. 5 and 6, the mounting boards 11a and 11b are provided with an LED load 161 in which a plurality of LEDs (Light Emitting Diodes) 12a are mounted in the longitudinal direction. An LED is an example of a semiconductor light emitting device. As shown in FIG. 3, the power supply substrate 7 is housed inside the substantially semi-cylindrical housing 2 and fixed so as not to move inside the housing 2. Moreover, in the case of the illuminating device 300, the lead wires 6a and 6b are shorter than the lead wires 6c and 6d.

  The current rectified to a direct current by the electronic component 9 is supplied to the mounting substrates 11a and 11b via the lead wires 13a and 13b shown in FIG. The mounting boards 11a and 11b arranged in parallel in the longitudinal direction are electrically connected by lead wires and jumper wires not shown. In this example, two mounting boards 11a and 11b are illustrated as mounting boards for mounting the LED load 161, but one or three or more mounting boards may be provided.

  As shown in FIGS. 5 and 6, in the case of the lighting device 300, the power supply substrate 7 is disposed below the mounting substrate 11a, and nothing is disposed on the mounting substrate 11b side. In other words, the mounting substrate 11b is planarly configured such that the inside of the housing 2 is hollow. Further, the mounting boards 11 a and 11 b are attached to the flat portion 14 which is a portion corresponding to the semicircular chord of the housing 2. Sheet-like resin members 10a and 10b are disposed between the flat portion 14 and the mounting substrates 11a and 11b, respectively, so as to be sandwiched between the flat portion 14 and the mounting substrates 11a and 11b. There is.

  As shown in FIGS. 3 and 4, the power supply substrate 7 to which the lead wires 6a and 6b and the lead wires 6c and 6d are respectively connected at both ends is a resin which is a cover member extending in the longitudinal direction as shown in FIG. The periphery is covered with a holder 30 made of aluminum. At the tips of the lead wires 6a and 6b and at the tips of the lead wires 6c and 6d, cap portions for inserting the connectors 16 are provided. The holder 30 is a continuous cylindrical component having a long shape having a length equal to or greater than that of the power supply substrate 7 and having no cut portion in the cross-sectional shape. The holder 30 can be formed by a molding method such as extrusion molding, pultrusion molding, injection molding and the like. The material of the holder 30 is, for example, PC (polycarbonate) or PA (nylon).

  As shown in FIG. 7, the holder 30 can be housed inside the housing 2 and has substantially the same cross-sectional shape in the longitudinal direction. The power supply substrate 7 is integrated with the holder 30 by being detachably mounted to the holder 30.

  That is, as shown in FIG. 7, on the side surfaces 30a and 30b located in the width direction intersecting the longitudinal direction of the holder 30, receiving parts 31a and 31b are formed so as to protrude in the width direction. The pedestals 31 a and 31 b function as guide rails when the power supply substrate 7 is inserted into the holder 30 from the end side. The cradles 31 a and 31 b support the power supply substrate 7 such that a separated portion (space portion) 32 is formed between the power supply substrate 7 and the bottom 30 c of the holder 30 after the power supply substrate 7 is inserted. The spacing portion 32 is for securing a distance Z1 such that the lead wire of the electronic component 9 shown in FIG. 3 protruding from the power supply substrate 7 does not touch the holder 30, or the electrical insulation can be secured.

  The holder 30 separates the power supply substrate 7 from the housing 2 inside the housing 2 by covering the entire (peripheral) of the power supply substrate 7 from the outside. The holder 30 contacts the inner side surface of the housing 2 in the housing 2 as shown in FIG. In order to make the holder 30 slippery in the housing 2, the surface in contact with the inner side surface of the housing 2 is a smooth surface. In the case of this example, the holder 30 has a cross-sectional shape without a cut portion for dividing the holder 30. Therefore, when the power supply substrate 7 is installed in the holder 30, the power supply substrate 7 is inserted into the holder 30 from the end of the opened holder 30. The holder 30 and the power supply substrate 7 are integrated before being attached to the housing 2 and configured as a power supply substrate unit, and are inserted into the housing 2 from the end of the housing 2 in the state of the power supply substrate unit.

  According to such a configuration, the resin holder 30 which covers the periphery of the power supply substrate 7, separates the power supply substrate 7 from the housing 2, and which can be accommodated in the housing 2 has a substantially identical cross section and extends in the longitudinal direction. Since it has, it can maintain electrical insulation with the housing | casing 2, and can ensure high safety. Further, since the coating of the insulating material does not have to be performed on the inside of the housing 2 in order to secure the electrical insulation, the housing 2 can be manufactured at low cost. Furthermore, since the inside of the case 2 can be separated into the power supply substrate 7 and the case 2 by the holder 30 and separated, even if the lead wires 13a and 13b of the electronic component 9 are projected, the case 2 may be touched. It can be manufactured without using expensive parts such as chip parts.

  Further, in the case of the lighting apparatus 300, since the holder 30 (the bottom 30c of the holder 30) is provided between the power supply substrate 7 and the mounting substrates 11a and 11b, the heat of the power supply substrate 7 is not easily transmitted to the mounting substrates 11a and 11b. The influence of heat on the LED load 161 is uniform in all the LEDs. For this reason, it is possible to prevent the inconvenience that the lifetime of the LED is partially shortened with the passage of time.

  Further, since the contact surface of the holder 30 integrated with the power supply substrate 7 is smooth, the frictional resistance can be reduced, and the power supply substrate unit can be slid in the housing 2. For this reason, the operation | work which inserts the connector 16 in the nozzle | cap | die part of both ends can be facilitated.

  In addition, since the cross-sectional shape of the holder 30 is not broken and is formed continuously, the electronic component 9 does not directly contact the housing 2, and the electrical insulation with the housing 2 is maintained. It is possible to secure high safety. In addition, since it is not necessary to coat the inside of the housing 2 in order to ensure electrical insulation, the housing 2 can be manufactured inexpensively.

  The lighting circuit 101 has a plurality of lighting means as a drive circuit for lighting the semiconductor light emitting element portion 160, and, for example, the first lighting means 110, the second lighting means 120, and the third lighting means 130. There are three lighting means.

  The three lighting means of the first lighting means 110, the second lighting means 120, and the third lighting means 130 are provided in parallel so as to be connectable to the semiconductor light emitting element unit 160, and signals from the controller 150 By switching the switching means 140 (switch), any one of the three lighting means 110 to 130 is connected to the semiconductor light emitting element unit 160, and the semiconductor light emitting element unit 160 is connected with the selected lighting means. It is possible to light.

  The current value detection unit 170 detects the current value of the current flowing to the semiconductor light emitting element unit 160. The controller 150 selects the optimum lighting means for the connected fluorescent lamp ballast 203 based on the detection value input from the current value detection unit 170, the input from the frequency detection means 180, etc. Control on and off of the lighting means.

  The semiconductor light emitting element unit 160 can switch between series / parallel connection by the semiconductor light emitting element switching unit 190. The details of each part will be described below.

(First lighting means)
FIG. 9 is a circuit diagram of the lighting apparatus 300 including the lighting circuit 101 when the first lighting means 110 and the LED load 161 are connected by the switching means 140, and the commercial power source E, the fluorescent light ballast 203, and FIG. 5 is a circuit diagram of mounting boards 11 a and 11 b of the illuminating lamp 100 and a lighting circuit 101 provided on the power supply board 7.

  The first lighting means 110 is a suitable lighting means when an inverter ballast is connected as the fluorescent lamp ballast 203.

  As shown in FIG. 9, the lighting device 300 includes a commercial power supply E, a fluorescent lamp ballast 203, bridge diodes (also referred to as "BD") 102 and 103 for full-wave rectifying an AC signal, and a controller ("CNT"). (Also referred to as “inductor element“ L ”) 112 connected to the bridge diodes 102 and 103, and the other of the inductance 112 and the reference point of the bridge diodes 102 and 103 are connected by the controller 150 Active switch (an example of a switching element) 111, a diode (a diode element, also referred to as "D") 113 for rectifying a signal switched by the active switch 111, and a signal rectified by the diode 113 are smoothed. Capacitors (capacitive element, “C” Comprising referred to as) 104, an LED load 161, a current sense resistor 171, a. The active switch 111, the inductance 112, and the diode 113 constitute a switching converter.

  The illumination circuit 101 including the bridge diodes 102 and 103, the controller 150, the active switch 111, the inductance 112, the diode 113, the capacitor 104, the LED load 161, and the current sense resistor 171 is mounted on the mounting substrates 11a and 11b of the illumination lamp 100. And the power supply substrate 7.

  The first lighting means 110 includes bridge diodes 102 and 103, an active switch 111, an inductance 112, a diode 113, and a capacitor 104. Here, the part of the switching converter shown by the dotted line in the figure constitutes the main part of the first lighting means 110, and although not shown in FIG. 9, the part shown by the dotted line of the first lighting means 110 It is provided in parallel with the main part of the second lighting means 120 and the third lighting means 130. Then, the connection with the LED load 161 can be switched by the switching means 140.

  Although the bridge diodes 102 and 103 and the capacitor 104 are used as common circuit elements of each lighting means, each lighting means may be provided individually.

  The bridge diodes 102 and 103 full-wave rectify the AC signal supplied from the commercial power source E via the fluorescent lamp ballast 203.

  The controller 150 controls the on / off timing of the active switch 111. Specifically, the controller 150 generates a gate signal of the active switch 111, outputs the generated gate signal to the active switch 111, and controls the on / off timing of the active switch 111 by driving the active switch 111. Do.

  Here, controller 150 sets the zero-cross timing (full-wave rectified AC signal) of the AC signal (AC voltage Vm in the example shown in FIG. 9) full-wave rectified by bridge diodes 102 and 103 to the reference potential of the bridge diode. The active switch 111 is controlled to be turned on at a timing different from the timing at which the same potential is obtained. The waveform of the AC voltage Vm will be described later. The details of the controller 150 will also be described later.

  The switching converter is a converter that converts an AC signal (AC voltage Vm in the example shown in FIG. 9) full-wave rectified by the bridge diodes 102 and 103 into a DC signal, and is a so-called ACDC converter. The switching converter is a step-up converter, and the inductance 112 and the diode 113 are connected in series to the LED load 161, and the active switch 111 is connected in parallel.

  The capacitor 104 is a smoothing capacitor connected in parallel to the LED load 161, and removes an AC component contained in the DC current output from the switching converter.

  The LED load 161 is connected to the switching converter, and the DC signal converted by the switching converter is output. Specifically, the LED load 161 emits light when a DC voltage is applied from the switching converter and a DC current flows.

  The current sense resistor 171 is a resistor for detecting the current value of the current flowing through the LED load 161, and outputs the terminal voltage Vcs to the controller 150.

  FIG. 10 is a block diagram showing an example of the configuration of the controller 150. As shown in FIG. As shown in FIG. 10, the controller 150 includes a zero cross detection unit 151, a current detection unit 152, a phase selection unit 153, and a gate signal generation unit 154.

  The zero cross detection unit 151 detects the zero cross timing of the AC signal (AC voltage Vm in the example shown in FIG. 9) full-wave rectified by the bridge diodes 102 and 103. Then, the zero cross detection unit 151 outputs, to the gate signal generation unit 154, a zero signal that becomes High at the zero cross timing and becomes Low at other than the zero cross timing. The waveform of the zero signal will be described later. Examples of the zero cross detection unit 151 include a comparator.

  The current detection unit 152 detects the current value iled of the current flowing to the LED load 161. Specifically, the current detection unit 152 AD converts the terminal voltage Vcs output from the current sense resistor 171, and the current value of the current flowing to the LED load 161 from the voltage after AD conversion and the resistance value of the current sense resistor 171 It detects iled and outputs it to the phase selection unit 153. The resistance value of the current sense resistor 171 is assumed to be known in the current detection unit 152. Examples of the current detection unit 152 include an AD converter and a divider circuit.

  The phase selection unit 153 selects the phase phi from the zero cross timing at which the current flowing through the LED load 161 becomes the target current based on the current value iled detected by the current detection unit 152. Then, the phase selection unit 153 outputs the selected phase phi to the gate signal generation unit 154. The details of the selection of the phase phi will be described later.

  The phase selection unit 153 also outputs a duty signal indicating the duty ratio (an example of a predetermined duty ratio) of the gate signal of the active switch 111 to the gate signal generation unit 154.

  Here, the duty ratio of the gate signal of the active switch 111 is generally set such that the output voltage of the switching converter becomes a target voltage. However, it is assumed that the lamp 100 is connected (mounted) to various types of fluorescent lamp ballasts 203. The value of the AC voltage output from the fluorescent lamp ballast 203 is not the same for all the fluorescent lamp ballasts 203, and differs depending on the type of the fluorescent lamp ballast 203. For this reason, regardless of the type of the fluorescent lamp ballast 203, the duty ratio can not be set so that the output voltage of the switching converter becomes the target voltage.

  Therefore, control is not performed to set the output voltage of the switching converter as the target voltage, and the duty ratio is set to a fixed value. As a fixed value, 50% is mentioned, for example. This is because it is preferable to secure the amount of reactive power generated by the switching converter. However, the duty ratio is not limited to 50%, and may be a value other than this.

  The gate signal generation unit 154 generates a gate signal based on the zero cross timing detected by the zero cross detection unit 151, the phase selected by the phase selection unit 153, and the duty ratio from the phase selection unit 153, and based on the gate signal. Control the on / off timing of the active switch 111;

  The gate signal is a PWM (Pulse Width Modulation) signal that switches from Low to High based on a timing shifted from the zero cross timing by a specified phase as a base point, and switches Low and High based on the duty ratio thereafter. The gate signal generation unit 154 calculates and sets the cycle of the frequency of the PWM signal from the zero signal. This allows the PWM signal to be synchronized to the zero signal. Also, the waveform of the PWM signal will be described later.

  Here, the details of the selection of the phase phi will be described. First, the phase selection unit 153 sequentially sets different phases in the gate signal generation unit 154, and the gate signal generation unit 154 sequentially generates gate signals having different phases and outputs the gate signals to the active switch 111. Next, the current detection unit 152 detects the current value of the current flowing through the LED load 161 for each of the generated gate signals, and the phase selection unit 153 is closest to the target current among the plurality of detected current values. Select the phase of the gate signal that has become the current value.

  FIG. 11 is a diagram showing an example of the waveforms of the AC voltage Vm, the zero signal, and the PWM signal. The ton of the PWM signal indicates a period during which the PWM signal is on, that is, High, and tp indicates one cycle of the PWM signal. Ton is a signal delayed by a phase phi from the zero signal.

  FIG. 12 is a flowchart showing an example of phase selection processing (phase calibration).

  First, the phase selection unit 153 sets an initial phase (S101), and the gate signal generation unit 154 generates a gate signal of the initial phase and outputs the gate signal to the active switch 111.

  Subsequently, the current detection unit 152 detects the current value of the current flowing through the LED load 161 in response to the gate signal being output to the active switch 111 (S102).

  When the measurement of all phases is not completed (S103: No), the phase selection unit 153 increments and sets the phase setting (S104), and the gate signal generation unit 154 generates a gate signal of the incremented phase. And output to the active switch 111. Then, the process returns to step S102.

  When the measurement of all phases is completed (S103: Yes), the relationship between the current value flowing through the LED load 161 and the phase as shown in FIG. 13 is obtained, so the current value closest to the target current is obtained. The phase optimum value is selected (S105).

  13A does not reach the target value when the current flowing through the LED load 161 reaches the target value, but FIG. 13C achieves the energy saving effect when the energy saving effect is obtained. An example of the case where it can not be As shown in FIG. 13, by setting the target current and the threshold value for determining the energy saving effect, it is possible to determine whether or not the target value is reached and whether there is an energy saving effect.

  Here, although there are a constant current control method, an apparent power constant control method, and an active power constant control method as a control method of an output waveform of the fluorescent lamp ballast 203, reactive power is generated in the active power constant control method. If this is done, an excessive current not expected by the ballast will be output, which may cause failure or destruction of the fluorescent lamp ballast 203.

  Therefore, when the plurality of current values detected by the current detection unit 152 have the same value, the phase selection unit 153 selects 0 as the phase. This is because when the current value of the current flowing through the LED load 161 does not change even if the phase is changed, the fluorescent lamp ballast 203 adopts the constant active power control method, and the power saving effect is obtained even if the phase is changed. It is because it can not be obtained and may cause failure or destruction of the fluorescent lamp ballast 203.

  The effect in the case of making it light using the 1st lighting means 110 is demonstrated, referring FIGS. 14-16. FIG. 15 is a diagram showing an example of the input voltage V, the gate signal G, the input current I, and the power of the conventional switching converter when the above phase control is not performed, and FIG. It is a figure which shows an example of the input voltage V of the switching converter at the time of performing, the gate signal G, the input current I, and electric power. In FIG. 16, the phase is delayed by 60 ° from the zero cross timing. Further, in FIG. 14, it is shown at which position the input voltage V, the gate signal G, and the input current I are.

  As apparent from comparison between FIG. 15 and FIG. 16, it is understood that the average power is smaller in FIG. 16 than in FIG. 15 by performing phase control to generate reactive power. As a result, the power consumption output from the switching converter and consumed by the LED load 161 is also smaller in FIG. 16 than in FIG. 15, and a power saving effect is obtained.

  As described above, in the first lighting means 110, the apparent power constant control ballast can be lighted by the switching converter of the booster circuit configuration. Although the case where the switching converter is a step-up type has been described above as an example, the switching converter may be a step-down type.

  FIG. 17 is another example of the circuit diagram of the lighting apparatus 300 including the commercial power source E, the fluorescent lamp ballast 203, the mounting boards 11a and 11b of the lighting lamp 100, and the lighting circuit 101 provided on the power supply board 7. is there. In the lighting device 300 shown in FIG. 17, the switching converter is a step-down converter, and the active switch 111 and the inductance 112 are connected in series to the LED load 161, and the diode 113 is connected in parallel.

  By using the first lighting means 110, reactive power is generated using the active switch instead of the inductance, so generation of back electromotive force can be prevented, and power saving and safety can be improved.

  Further, by using the first lighting means 110, the reactive current is intentionally generated in the fluorescent lamp ballast 203 which controls the reactive power to a constant level, and the current flowing to the semiconductor light emitting element is adjusted by the phase delay amount, Can vary.

  However, depending on the fluorescent lamp ballast 203, there are also a fluorescent lamp ballast 203 which controls the effective power consumed in the illumination part constant, and a fluorescent lamp ballast 203 which is turned off if not operated with the same impedance as the fluorescent lamp. In order to achieve this, appropriate control is required depending on the type of ballast.

(Second lighting means)
FIG. 18 is a circuit diagram of the lighting apparatus 300 including the lighting circuit 101 when the second lighting means 120 and the LED load 161 are connected by the switching means 140, and the commercial power source E, the fluorescent light ballast 203, and FIG. 5 is a circuit diagram of mounting boards 11 a and 11 b of the illuminating lamp 100 and a lighting circuit 101 provided on the power supply board 7. The description of the points already described will be omitted as appropriate.

  The second lighting means 120 is a suitable lighting means when a rapid ballast or a glow ballast is connected as the fluorescent lamp ballast 203. In addition, it is a suitable lighting means also when the lamp 100 is directly connected to the commercial power source E without passing through the fluorescent lamp ballast 203.

  As shown in FIG. 18, the lighting device 300 is connected to a commercial power source E, a fluorescent lamp ballast 203, bridge diodes 102 and 103 for full-wave rectification of AC signals, a controller 150 and bridge diodes 102 and 103. An active switch 121 whose on / off is controlled by the controller 150, an inductance 122 connected to the active switch 121 and the diode 123, and a diode 123 connected between the reference points of the active switch 121 and the bridge diodes 102 and 103; A capacitor 104 connected between one of the inductances 122 and the reference point of the bridge diodes 102 and 103, an LED load 161, and a current sense resistor 171 are provided. Also, a PFC converter (switching converter) is configured by the active switch 121, the inductance 122, and the diode 123.

  The second lighting means 120 includes bridge diodes 102 and 103, an active switch 121, an inductance 122, a diode 123 and a capacitor 104. Here, the portion of the PFC converter shown by the dotted line in the figure constitutes the main part of the second lighting means 120, and although not shown in FIG. 18, the portion shown by the dotted line of the second lighting means 120 is the first It is provided in parallel with the main part of the lighting means 110 and the third lighting means 130, and the connection with the LED load 161 can be switched by the switching means 140.

  The bridge diodes 102 and 103 full-wave rectify the alternating current signal supplied from the commercial power source E via the rapid ballast or the glow ballast.

  The controller 150 controls the on / off timing of the active switch 121. Specifically, the controller 150 generates a gate signal of the active switch 121, outputs the generated gate signal to the active switch 121, and drives the active switch 121.

  Here, the PFC converter is a converter that converts the AC signal full-wave rectified by the bridge diodes 102 and 103 into a DC signal, and improves the power factor of the voltage and current output from the fluorescent lamp ballast 203. The PFC converter is a step-down converter, and the active switch 121 and the inductance 122 are connected in series to the LED load 161, and the diode 123 is connected in parallel.

  The capacitor 104 is a smoothing capacitor connected in parallel to the LED load 161, and removes an AC component contained in the DC current output from the PFC converter.

  The LED load 161 is connected to the PFC converter, and a DC signal converted by the PFC converter is output. Specifically, the LED load 161 emits light when a DC voltage is applied from the PFC converter and a DC current flows.

  The current sense resistor 171 is a resistor for detecting the current value of the current flowing through the LED load 161, and outputs the terminal voltage Vcs to the controller 150.

  Incidentally, as shown in FIG. 19, the second lighting means 120 is a PFC even when the commercial power source E is directly connected to the lighting circuit 101 without passing through the fluorescent lamp ballast 203 such as a rapid ballast or a glow ballast as shown in FIG. The LED load 161 can be turned on by the converter.

  As described above, according to the second lighting means 120, even when the fluorescent lamp ballast 203 such as the glow ballast or the rapid ballast is connected or directly connected to the commercial power source E, By constant current operation, the LED load 161 can be lit while maintaining a high power factor.

(Frequency detection means)
Next, the frequency detection means 180 (frequency detection circuit) will be described. The frequency detection means 180 is a circuit for determining the type and presence of the fluorescent lamp ballast 203 connected to the lamp 100.

  FIG. 20 shows an example of the frequency detection means 180 for determining the type and presence of the fluorescent lamp ballast 203 connected to the illumination circuit 101.

  The frequency detection means 180 includes voltage dividing resistors 181 and 182 for dividing the outputs of the bridge diodes 102 and 103, and a comparator 184 for comparing the voltage divided by the voltage dividing resistors 181 and 182 with a constant voltage (power supply 183). And the output of the comparator 184 is input to the controller 150.

  The controller 150 has a timer 155, and detects the frequency by measuring the inversion interval time of the comparator 184 with the timer 155.

  In the example shown in FIG. 20, the frequency detection means 180 is connected to the commercial power source E via the fluorescent lamp ballast 203, but the commercial power source E is directly connected (see FIG. 19). Can also detect the frequency.

  Further, the configuration of the frequency detection means 180 is an example, and in the example of FIG. 20, although the frequency is detected using the comparator 184, for example, the voltage divided by the voltage dividing resistors 181 and 182 can be It may be input to the controller 150 via a Schmitt trigger.

  By providing the frequency detection unit 180 described above, the controller 150 can measure the input voltage frequency input to the illumination circuit 101 based on the input of the frequency detection unit 180. Specifically, in the case where either a glow ballast or a rapid ballast is connected as the fluorescent lamp ballast 203 to the lighting circuit 101, or when the commercial power source E is connected, the input voltage frequency is the commercial frequency. Is detected. On the other hand, when an inverter ballast is connected to the lighting circuit 101 as the fluorescent lamp ballast 203, the input frequency input to the lighting circuit 101 is generally an input frequency 1000 times or more the commercial frequency. This makes it possible to distinguish between the case where the inverter ballast is connected and the case where any one of the glow ballast, the rapid ballast, and the commercial power source E is connected.

(Third lighting means)
FIG. 21 is a circuit diagram of the lighting apparatus 300 including the lighting circuit 101 when the third lighting means 130 and the LED load 161 are connected by the switching means 140, and the commercial power source E, the fluorescent light ballast 203, and FIG. 5 is a circuit diagram of mounting boards 11 a and 11 b of the illuminating lamp 100 and a lighting circuit 101 provided on the power supply board 7. The description of the points already described will be omitted as appropriate.

  The third lighting means 130 is a suitable lighting means when the active light constant control method ballast is connected as the fluorescent lamp ballast 203.

  As shown in FIG. 21, the lighting device 300 includes a commercial power source E, a fluorescent lamp ballast 203, bridge diodes 102 and 103 for full-wave rectification of AC signals, a controller 150, an LED load 161, and a current sense resistor. And a Pch switch element 132 for connecting the bridge diodes 102 and 103 to the LED load 161 and the current sense resistor 171, an Nch switch element 131 for controlling on / off of the Pch switch element 132, and a Pch switch element 132. A resistor element 133 and a resistor element 134 that determine a gate-source voltage are provided. Further, the controller 150 controls the on / off of the Nch switch element 131.

  The third lighting means 130 includes bridge diodes 102 and 103, a Pch switch element 132, an Nch switch element 131, a resistive element 133, and a resistive element 134. Here, the portion shown by the dotted line in the figure constitutes the main part of the third lighting means 130, and although not shown in FIG. 21, the portion shown by the dotted line of the third lighting means 130 is the first lighting means 110. The second lighting means 120 is provided in parallel with the main part of the second lighting means 120, and the connection with the LED load 161 can be switched by the switching means 140.

  In the third lighting means 130, a folded voltage obtained by full-wave rectification of the output voltage of the fluorescent lamp ballast 203 by the bridge diodes 102 and 103 is directly applied to the LED load 161. That is, the outputs of the bridge diodes 102 and 103 and the LED load 161 can be connected and lighted without solving the switching converter. At this time, the load impedance viewed from the fluorescent lamp ballast 203 is the same as the impedance of the LED load 161. On the other hand, as in other lighting means, in the case of passing through a switching converter or a PFC converter, the load impedance is converted by the step-up ratio or the step-down ratio.

(Semiconductor light emitting element switching means)
In the configuration including the third lighting unit 130, it is preferable to further include a semiconductor light emitting element switching unit 190.

  FIG. 22 shows an example of the semiconductor light emitting element switching means 190. The semiconductor light emitting element switching unit 190 includes a first switch element 191, a second switch element 192, and a diode 193.

  Then, the controller 150 switches the connection state between the first LED load 161 a and the second LED load 161 b by controlling the first switch element 191 and the second switch element 192.

  That is, when the controller 150 turns off the first switch element 191 and the second switch element 192, the first LED load 161a and the second LED load 161b are connected in series via the diode 193.

  At this time, assuming that the impedance of the fluorescent lamp at the time of lighting the fluorescent lamp and the series combined impedance at the time of series lighting of the first LED load 161a and the second LED load 161b become the same, the third lighting means shown in FIG. When lighting is performed using 130, it is possible to secure the lighting state regardless of the protection detection operation in all the ballasts.

  On the other hand, when the controller 150 turns on the first switch element 191 and the second switch element 192, the first LED load 161a and the second LED load 161b are connected in parallel.

  At this time, when lighting is performed by the third lighting means 130 shown in FIG. 21, the combined impedance is lower than that in the series connection, so that it is possible to save power with a ballast or the like that throttles output power when load resistance decreases. Become.

  As described above, according to the third lighting unit 130 including the semiconductor light emitting element switching unit 190, the LED loads 161 can be switched in series or in parallel. For this reason, even if the phase is changed, such as the fluorescent lamp ballast 203 of the active power constant control system, the power saving effect can not be obtained, and if there is a possibility of causing failure or destruction of the fluorescent lamp ballast 203 Power saving can be realized by reducing the impedance by switching the number of lights of the LED load 161 without shifting the power. Furthermore, by providing the number of lights that can be turned on with an impedance similar to that at the time of lighting a fluorescent light, it is possible to ensure the lighting state.

  In addition, as shown in FIG. 8, in the case where the first to third lighting means 110, 120, 130 are provided, when the LED load 161 is lighted by the first and second lighting means 110, 120, The first switch element 191 and the second switch element 192 of the semiconductor light emitting element switching means 190 may be turned on.

(Lighting means selection processing)
FIG. 23 is a flowchart showing an example of lighting means selection processing (referred to as lighting calibration) in which the lowest power state can be selected while lighting the LED load 161 in the lighting 100. The lighting means selection process is executed by the controller 150 of the lighting circuit 101.

  The illuminating lamp 100 includes a first lighting unit 110 (FIG. 9), a second lighting unit 120 (FIG. 18), and a third lighting unit 130 (FIG. 21), and a semiconductor light emitting element switching unit 190 (FIG. 22).

  Therefore, as the lighting state of the LED load 161, the case of lighting by the first lighting means 110 (hereinafter referred to as lighting state 1) and the case of lighting by the second lighting means 120 (hereinafter referred to as lighting state 2) ), When the semiconductor light emitting element switching means 190 is turned off by the third lighting means 130 (hereinafter referred to as lighting state 3), the semiconductor light emitting element switching means 190 is turned on by the third lighting means 130 and lighted In the case where the lighting state is 4 (hereinafter referred to as lighting state 4), a total of four lighting states can be selected and controlled.

  Further, the controller 150 includes a storage unit capable of storing the current value flowing to the semiconductor light emitting element unit 160 detected by the current value detection unit 170 in each of the lighting states 1 to 4.

  An example of control will be described below. First, when the power is turned on (S201), the controller 150 measures the input voltage frequency input to the lighting circuit 101 based on the input from the frequency detection means 180 (S202).

  As described above, when any of the commercial power supply E (AC), the glow ballast (G), and the rapid ballast (R) is connected to the lighting circuit 101 (S202: Yes), the lighting circuit 101 is input. The commercial input frequency is detected. When the commercial frequency is detected, the lighting state 2 is set (S203).

  On the other hand, in other cases (S202: No), for example, when an inverter ballast is connected to the lighting circuit 101, the input frequency input to the lighting circuit 101 is generally an input frequency at least 1000 times the commercial frequency. It becomes. For this reason, when the frequency of the inverter ballast is detected, first, in order to turn on the illumination, it is lit in the lighting state 3 (S204).

  Here, when the lighting calibration has already been completed for the connected fluorescent lamp ballast 203 (S205: Yes), that is, when the lighting calibration result is already recorded in the storage unit of the controller 150, the lighting calibration is performed. The lighting is performed in any of the lighting state 3, the lighting state 4, and the lighting state 1 based on the result of the display (S206, S207, and S227 to S229).

  On the other hand, when the lighting calibration is not completed for the connected fluorescent lamp ballast 203 (S205: No), that is, when the lighting calibration result is not recorded in the storage unit of the controller 150, the following lighting calibration (S208 to S226).

  Here, Cal1 is a parameter indicating the presence or absence of detection of the current value flowing to the semiconductor light emitting element unit 160 by the current value detection unit 170 in the lighting state 4, and Cal1 = 0 is a state not yet detected, Cal1 = 1 Means the detected state.

  Further, Cal2 is a parameter indicating whether or not phase calibration (FIG. 12) is performed in the lighting state 1, Cal2 = 0 is not yet performed, and Cal2 = 1 is already performed. I mean.

  In the lighting calibration, first, when Cal1 = 0 from the lighting state 3 (S208: Yes), the lighting state is switched to the lighting state 4 (S210). The current value flowing to the LED load 161 in the lighting state 4 is recorded, and Cal1 = 1 is set (S211). On the other hand, if Cal1 ≠ 0 (S208: No), the process proceeds to S209 (described later).

  After S211, when lighting is performed in the lighting state 4 (S212: Yes), the lighting state 4 is switched to the lighting state 3 (S213), the LED load 161 is made in series, and then the lighting state 3 is switched to the lighting state 1 ( S214).

  Phase calibration is performed in the lighting state 1. In S214, an initial phase is set (S101 in FIG. 12), and then, when lighting is performed in lighting state 1 of S214 (S215: Yes), Cal2 = 1 is set (S216), and phase calibration in lighting state 1 is performed. It carries out (S217, S102-S105 of FIG. 12). When it does not light up (S215: No), it moves to S201. When the light is turned off during phase calibration (S218: No), the process proceeds to S201.

  When the light flows in the lighting state 1 (S218: Yes) and the current flowing through the LED load 161 reaches the target value in the phase calibration in the lighting state 1 (S219: Yes, FIG. 13A), the lighting calibration result Is determined to be in the lighting state 1 (S226), and is lit in the lighting state 1 (S227).

  On the other hand, when the current flowing through the LED load 161 does not reach the target value (S219: No), it is determined whether there is an energy saving effect (S220).

  When there is an energy saving effect (S220: Yes, FIG. 13B), when lighting in the lighting state 4 (S223: Yes), the one where the current flowing to the LED load 161 is lower in the lighting state 1 and the lighting state 4 It determines as a lighting calibration result (S224-S226), and makes it light in each lighting state (S227, S229).

  If the energy saving effect can not be obtained (S220: No, FIG. 13C), it is judged whether or not the light is lit in the lighting state 4 (S221). If it is lit (S221: Yes), the light is lit in the lighting state 4 (S225, S229). When the lamp is not lit (S221: No), the lamp is lit in the lighting state 3 (S222, S228).

  In addition, when switching to the lighting state 4 (S210), when the protection circuit of the fluorescent lamp ballast 203 operates and the LED load 161 is extinguished (the current is less than a predetermined threshold) (S212: No), Next, when the power is turned on, the state is not shifted to the lighting state 4 (S208: No), the state is shifted to the lighting state 1 (S209: Yes), and phase calibration is performed (S214, S217).

  Then, when the current flowing through the LED load 161 reaches the target value in the phase calibration in the lighting state 1 (S219: Yes), the phase delay amount at that time is determined as the phase calibration result, and the lighting calibration result is turned on. The state 1 is determined (S226, S227).

  On the other hand, when the current flowing through the LED load 161 does not reach the target value (S219: No), the phase delay amount with the lowest current flowing through the LED load 161 is determined as the phase calibration result, and the lighting calibration result is in the lighting state It is determined to be 1 (S226, S227).

  When the light is turned on in the lighting state 1 but turned off in the lighting state 1, the lighting calibration is determined as the lighting state 4 without shifting to the lighting state 1 when the power is turned on next. When lighting is performed in both the lighting state 1 and the lighting state 4, the one with the lower current flowing through the LED load 161 is determined as the lighting calibration result (S224 to S227, S229).

  As described above, in the lighting calibration of FIG. 23, the current value for each lighting unit stored in the storage unit of the controller 150 and the current value when switched by the semiconductor light emitting element switching unit 190 are closest to the target current value. The lighting means can be selected to select a lighting method for saving power and the lighting can be performed.

  In addition, when the lighting calibration goes into a non-lighting state, avoidance of lighting by the lighting means that became non-lighting in the next lighting, or after completion of the lighting calibration, in the storage unit at the time of relighting, The processing is simplified by turning on the stored lighting means.

  As described above, according to the illuminating lamp 100, the controller 150 can select the optimum lighting means for the fluorescent lamp ballast 203, thereby achieving both power saving and normal lighting.

  That is, even when directly connected to various types of fluorescent lamp ballast 203 and commercial power source E, depending on the fluorescent lamp ballast 203 or commercial power source E connected to the lamp 100 at the time of lighting calibration, The LED load 161 can be operated by securing the lighting operation from the plurality of lighting units and using the lighting unit that achieves the most power saving or the lighting unit that achieves the desired power.

  In addition, although the example which the illuminating lamp 100 provided with three lighting means of the 1st-3rd lighting means 110, 120, 130 was demonstrated, if a lighting means is provided with a selectable at least 2 or more lighting means Good. Further, at least one of the first to third lighting means 110, 120, and 130 and the other lighting means may be selectable.

(Recalibration)
As described above, the lighting lamp 100 performs lighting calibration and selects the most suitable lighting means according to the presence or absence of the ballast and the type of the ballast, thereby saving power and stably lighting. It makes it compatible.

  If the lamp 100 is installed in the lamp, then usually it will continue to be used for a long period of time, so the lighting calibration is performed only at the first start and the result is recorded, and at the second and subsequent start, It will be made to light by the determined lighting system (S205 of FIG. 23).

  However, since the lamp 100 using the LED has a long life as compared with the fluorescent lamp, it is also assumed that the lamp changes in the use cycle as a product. That is, this is a case where the lighting calibration is diverted to lighting in another room different from the lamp for which the lighting calibration has been performed. In addition, there is also considered a case where the operating characteristic of the ballast changes with time due to the long life of the illuminating lamp 100 and the selected lighting state is not optimum.

  In such a case, it is desirable to perform lighting calibration again, that is, to perform so-called recalibration.

  As a method of recalibration, it is conceivable that the user has a means (hard reset means) that accesses the storage unit of the controller 150 to initialize the calibration result, but the construction-less LED lighting is a lamp It is difficult for the user to access the storage of the controller 150 and initialize the calibration result because the system operates only when the power is supplied from the device, and to perform a hard reset, It is necessary for the user to access a hard reset button, etc. of the construction-less LED light that is lit.

  However, since a lamp is generally not provided where the user can easily touch, resetting of the calibration result by this method is not realistic.

  As described above, there has been a problem that there is no means for the user to directly command re-calibration of the construction-less LED illumination to calibrate the lighting conditions.

  Therefore, the lamp according to the present embodiment (lamp 100) has rectifying means (rectifying portion 301) for full-wave rectifying an AC signal, and two or more lighting means, and the AC signal input from the rectifying means Accordingly, a lighting control unit (lighting control unit 302) for selecting one of the two or more lighting units and a light emitting unit (light emitting unit 303) whose light emission is controlled by the lighting unit selected by the lighting control unit. And reset means (reset detection unit 304) for resetting the lighting means selected by the lighting control means, and the reset means detects the presence or absence of the output signal (power signal VC) from the rectification means. At the same time, the switching time of the presence or absence of the output signal is detected to detect the pattern of the output signal, and when the pattern satisfies a predetermined condition, the lighting control means resets the lighting means. In addition, the code | symbol in embodiment and the application example are shown in a parenthesis.

  Therefore, the user can execute the recalibration instruction execution for the illumination light attached to the light fixture. Thereby, it is possible to cope with the switching of the lamp and the lighting control with respect to the temporal change of the lamp.

  Specifically, as described below, the power supply from the lamp to the lamp, that is, the presence or absence of the signal output of the ballast output is monitored to detect the interval and number of switching of the presence or absence of the output, and the signal pattern Is used as an instruction signal for recalibration. That is, the user can easily perform recalibration from the user side by turning on and off the illumination light so as to satisfy the predetermined condition.

First Embodiment
FIG. 24 shows an example of the lighting apparatus 300 including the lighting circuit 101 provided with reset detection means, which includes the commercial power source E, the fluorescent lamp ballast 203, the mounting boards 11a and 11b of the lamp 100, and the power board 7. It is a circuit diagram of the lighting circuit 101 provided.

  The lighting circuit 101 illustrated in FIG. 24 includes a rectifying unit 301, a lighting control unit 302, a light emitting unit 303, and a reset detecting unit 304. The rectifying unit 301, the lighting control unit 302, and the reset detecting unit 304 Functions as a lighting control device for lighting the light emitting unit 303.

  The rectifying unit 301 is bridge diodes 102 and 103 that full-wave rectify an AC signal. The light emitting unit 303 is a semiconductor light emitting element unit 160 (LED load 161). In addition, the current value detection unit 170 is included. Preferably, the semiconductor light emitting element switching unit 190 is also provided.

  The lighting control unit 302 determines the type of the fluorescent lamp ballast 203, and performs lighting calibration to select an optimal lighting method according to the determination result (first lighting means 110; second lighting means It includes the lighting means 120, the third lighting means 130), the switching means (switching means 140), and the control means (part of the controller 150) for the lighting calibration.

  Here, the lighting control unit 302 may have any function as long as it determines the type of the fluorescent lamp ballast 203 and selects an optimal lighting method according to the determination result. There is no limitation to the configuration of the switching means and the control means. Further, the lighting control unit 302 may be any device that can determine the type of at least two or more fluorescent lamp stabilizers 203, and may not be able to determine the case of direct connection to the commercial power source E.

  The lighting control unit 302 holds calibration data (calibration result) regarding optimal lighting after lighting calibration, but in the lighting circuit 101 shown in FIG. 24, calibration is performed from the reset detection unit 304 as described later. When the reset signal RST is input, calibration data regarding optimum lighting is initialized, and recalibration can be performed.

  The reset detection unit 304 is configured as part of the controller 150. When the output signal (power supply signal VC) of the rectification unit 301 is input to the reset detection unit 304 and the signal pattern of the output signal becomes a predetermined pattern, the lighting control unit 302 receives the calibration reset signal RST. Output.

  The reset detection unit 304 includes a detection control unit 310, a data storage unit 311, and a timer 312. FIG. 25 is a timing chart showing reset detection processing in the reset detection unit 304. FIG. 26 is a flowchart showing an example of reset detection processing performed by the reset detection unit 304 and the lighting control unit 302.

  The detection control unit 310 detects a time (which is a pulse width of the power supply signal VC) from the rise to the fall of the power supply signal VC input from the rectification unit 301.

  The data storage unit 311 is a storage unit that holds a reset access signal (counter value). The data storage unit 311 is a non-volatile memory, and includes, for example, an EEPROM (Electrically Erasable Programmable ROM). Therefore, the reset access signal is held even in the power-off state.

  The timer 312 is a clock means, and outputs a timing signal TM to the detection control unit 310.

The detection control unit 310 reads the reset access signal from the data storage unit 311 at system startup (R), and counts the reset access signal when the time from the rise to the fall of the power supply signal VC is equal to or less than a predetermined time. Up (increment) is performed, and the result is written to the data storage unit 311 (W).
Do.

  In addition, the detection control unit 310 reads the reset access signal from the data storage unit 311 at system startup (R), and asserts the calibration reset signal RST to the lighting control unit 302 when the value is a predetermined value. Do.

  That is, the reset detection unit 304 detects that the power switch is turned on / off within a predetermined time, counts up the reset access signal, and when the reset access signal reaches a predetermined value, calibration is performed. The reset signal RST is output.

  The details of the reset detection process in the reset detection unit 304 will be described with reference to the timing chart of FIG.

  When the power switch of the lamp 100 is turned on to supply power to the lamp 100, power is supplied from the fluorescent lamp ballast 203, and the power signal VC of the rectifying unit 301 rises.

  At this time, the detection control unit 310 counts the time from the rise to the fall of the power supply signal VC, and counts up the reset access signal in the case of 3 seconds or less. On the other hand, when the period from the rise to the fall of the power supply signal VC exceeds 3 seconds, the reset access signal is cleared.

  As described above, when the reset access signal is counted up and the count of the reset access signal is “2”, the calibration reset signal is turned on when the power switch is turned on and the power signal VC rises. RST is asserted.

  In the present embodiment, the period from the rise to the fall of the power supply signal VC for counting up the reset access signal is 3 seconds, but this time is a value that can be set arbitrarily. Further, although the count value of the reset access signal serving as a condition for asserting the calibration reset signal RST is “2”, this value is also a value that can be arbitrarily set.

  By the reset detection process described above, the user repeatedly turns on / off the power switch of the illumination lamp 100 within a predetermined interval (here, within 3 seconds) and (at this time, twice) at the time of activation ( Here, it is possible to reset the stored calibration result in the third time. Therefore, recalibration can be performed by the user performing a predetermined operation.

  An example of the reset detection process performed by the reset detection unit 304 will be described with reference to the flowchart of FIG.

  In the reset detection process, the power is supplied to the illumination lamp 100 (S301) to start the system. First, the detection control unit 310 reads the reset access signal from the data storage unit 311 and confirms the count value. (S302).

  When the count value of the reset access signal is "2" (S302: Yes), the calibration reset signal RST is asserted (S303). When the migration reset signal RST is asserted, the lighting control unit 302 initializes the calibration result and performs recalibration (S304).

  On the other hand, when the count value of the reset access signal is not “2”, that is, “1” or “0” (S302: No), the detection control unit 310 detects the rising of the power supply signal VC, which is the pulse width of the power supply signal VC. The time until is counted (S305).

  Next, if the pulse width of the power supply signal VC is 3 seconds or less (S306: Yes), the reset access signal is counted up, and the value is stored in the data storage unit 311 (S307). On the other hand, when the pulse width of the power supply signal VC exceeds 3 seconds (S306: No), the reset access signal is cleared and set to 0 (S308).

  As described above, when the reset detection process is performed when the power is turned on, it is possible to receive a recalibration execution instruction from the user.

  According to the illumination lamp according to the present embodiment described above, power saving can be achieved, and appropriate lighting control can be performed according to the lamp, and when the lamp changes or the operation characteristic of the ballast changes Even in this case, appropriate lighting control can be performed.

  Further, in the present embodiment, based on the output signal of the rectifying unit 301, it is detected that the switching on and off of the power supply has been repeated within a predetermined time, so stable operation can be realized.
