Description

  The present invention relates to a lighting device.

  A long tube fluorescent lamp is usually used for ceiling lighting and wall lighting. Further, in order not to feel the joint of the line-shaped illumination, for example, in indirect illumination, the end portion of the long tube-type fluorescent lamp is also placed in a groove portion that cannot be directly seen. Further, it has been proposed that the structure of the long tube fluorescent lamp itself is devised so that light is emitted to the end portion so that no joint is felt even if the fluorescent lamps are arranged in a line. (Patent Document 1) On the other hand, in recent years, as LEDs have been used, it has been proposed to use white LEDs for general ceiling lighting by making them compatible with fluorescent lamps.

It is a block diagram which shows the detailed structure of the LED illumination light of Example 2 of this invention. (Example 2) It is a block diagram which shows the detailed structure of the LED lighting lamp of Example 3 of this invention. (Example 3)

  FIG. 1 is an external view in various lighting states in Example 1 of the lighting apparatus according to the embodiment of the present invention. FIG. 1 (A1) shows a state in which the line-shaped LED lighting lamps 2, 4 and 6 are arranged in a straight line and all are lit. Each LED illumination lamp 2, 4 and 6 has a structure in which a large number of white LEDs 8, 10 and 11 and the like are arranged in a row and covered with a transmissive diffusive cover. In FIG. 1 (A1), the white LEDs 8, 10 and 11 etc. are schematically illustrated. However, in actuality, each of the LED lights 2, 4 and 6 has more white LEDs (for example, 288). Are arranged in rows.

  Also, since the LED lighting lamps 2, 4 and 6 are arranged close to each other, for example, the white LED 10 at the left end of the LED lighting lamp 2 in the drawing is close to the white LED 11 at the right end of the LED lighting lamp 4. Since the individual white LEDs cannot be identified because of the light transmitting position and the individual diffusive cover, each LED lighting 2, 4, and 6 is like a single continuous LED lighting. Emits light.

  FIG. 1 (A2) shows a state in which all of the LED lighting lamps 2, 4 and 6 are turned off. As described above, the simplest lighting state in the first embodiment is that the LED lighting lamps 2, 4 and 6 as a whole are a single LED lighting lamp between FIG. 1 (A1) and FIG. 1 (A2). Turns on or off. In the first embodiment, lighting control for each LED illumination lamp is also possible. FIG. (A3) is an example thereof, and the LED illumination lamp 2 is turned off and the LED illumination lamps 4 and 6 are turned off. Illumination as shown in the diagram (A3) is for lighting a lecture hall, for example, where the projection screen of the projector is on the LED illumination lamp 6 side and the audience's seat is on the LED illumination lamp 2 side. This is suitable for the case where is necessary.

  In Embodiment 1 of the present invention, the white LEDs in each of the LED lighting lamps 2, 4 and 6 can be controlled to be turned on independently for each of the six sections. Details thereof will be described later. As described above, in the first embodiment, each LED illumination lamp 2, 4 and 6 emits light like a single seamless LED illumination lamp. As shown in FIG. 1 (A3), it is not necessary to be at the border of the LED lighting, and it may be in the middle of the LED lighting. FIG. 1 (B1) to (B3) show this state.

  For example, in FIG. 1 (B1), 1/6 of the LED illumination lamp 2 is turned off together with the LED illumination lamps 4 and 6, and the remaining 5/6 of the LED illumination lamp 2 is turned on. In FIG. 1 (B2), the LED illumination lamp 6 and the LED illumination lamp 4 are turned off 4/6 from the left, and the remaining 2/6 of the LED illumination lamp 4 is illuminated with the LED illumination lamp 2. . What should be noted here is that the lighting portions of the LED illumination lamp 2 and the LED illumination lamp 4 appear to be lit seamlessly. In other words, the LED lighting lamps 2, 4, and 6 function as a single seamless LED lighting lamp, and the lighting / extinguishing break is in the middle of the LED lighting lamp 4. Similarly, in FIG. 1 (B3), 2/6 from the left of the LED illumination lamp 6 is turned off, and the remaining 4/6 of the LED illumination lamp 6 is turned on together with the LED illumination lamps 4 and 2. In this case, the delimiter between lighting and extinguishing is an intermediate part of the LED lighting lamp 6.

  As described above, the first embodiment emits light so that there is no joint between the LED lighting lamps, and the white LED in each LED lighting lamp is divided into a plurality of parts so that they can be controlled independently. Can be controlled flexibly. For example, in the lighting of the lecture hall where the projection screen of the projector described above is provided, it is possible to perform optimum lighting according to the conditions of the hall. In such control, it is not prevented that the turn-on and turn-off breaks accidentally become the boundary between the LED illumination lights as shown in FIG. 1 (A3). That is, from the viewpoint of delimiting between lighting and extinguishing, the boundary between the LED lighting lamps and the middle of the LED lighting lamps are completely equivalent. As will be described later, the actual change between the on / off division is easily operated by providing a lever that can move in the linear direction on the remote controller and sliding it in correspondence with the LED lighting 2 to 6 column directions. Is possible.

  In the first embodiment of the present invention, the brightness at the time of lighting can be dimmed by PWM (pulse width modulation) control, and the dimming is performed not only in the LED lighting unit but also in each of the above LED lightings. Control is possible independently for each of the six sections of the white LED. Therefore, as shown in FIG. 1 (A1), when all the LED lighting lamps 2, 4 and 6 are turned on, the brightness can be adjusted as a whole, and the brightness is adjusted by adding gradation to the column direction of the LED lighting lamps. Is possible. FIG. 1 (C1) to FIG. 1 (C3) illustrate this state.

  FIG. 1 (C1) is an example in which gradation is given in units of LED lighting lamps. LED lighting lamp 2 is controlled with a duty of 100%, LED lighting lamp 4 with a duty of 50%, and LED lighting lamp 6 with a duty of 25%. ing. In other words, this is an example in which the division of the duty change is the boundary of the LED lighting. On the other hand, FIG. 1 (C2) is an example in which gradation is given by independent control for each of the six sections of the white LEDs in each LED lighting. That is, 5/6 from the right of the LED lighting 2 is 100% duty, the remaining 1/6 of the LED lighting 2 and 4/6 from the right of the LED lighting 4 are 50% duty, and the remaining 2/2 of the LED lighting 4 6 and 4/6 from the right of the LED lighting 6 are controlled with a duty of 25%, and the remaining 2/6 of the LED lighting 6 is controlled with a duty of 13%. In other words, this is an example in which the division of the duty change is in the middle of the LED lighting. Also in this case, the boundary between the LED illumination lights having the same duty is continuous.

  FIG. 1 (C3) is an example in which the change of duty change is in the middle of the LED lighting as in FIG. 1 (2), but the duty does not change in one direction, but a series of LEDs Dimming is performed in the lighting lamps 2, 4 and 6 so that the brightness gradually decreases from the center toward both ends. Further, in the LED lighting lamps 2 and 6, two duty change breaks occur in the middle of the LED lighting lamp.

  Gradation dimming as shown in FIG. 1 (C1) to (C3) is suitable for lighting a room with a window during the day. In both FIG. 1 (C1) and FIG. (C2), there is a window on the left side of the room in the figure, and the lighting is turned off near the window that allows daylighting from the outside, so that the brightness of the whole room is uniform and power is saved It is intended. The same thing can be roughly done by completely turning off the LED illuminating lamp or a part thereof near the window by the control as shown in FIG. 1 (A1) and FIG. (B1) or FIG. (B3). Since the room lights may darken the image of the room, the ability to perform gradation dimming as shown in FIGS. 1 (C1) and (C2) makes the room brightness uniform and psychologically beneficial. is there. Note that gradation dimming as shown in FIG. 1 (C3) is suitable when there are windows on both sides of the room.

  FIG. 2 is a layout view when the lighting device according to the first embodiment is installed on the ceiling, and illustrates a state in which the ceiling 13 is looked up from below. FIG. 2 (A1) corresponds to the state of FIG. 1 (A1) in FIG. 1 and shows a state in which all LED illumination lamps arranged on the ceiling 13 are lit. In FIG. 2 (A1), the ceiling 13 includes a row of LED lamps 2, 14 and 16, and a total of columns of LED lamps 22, 24 and 26 in addition to the rows of LED lamps 2, 4 and 6. Three rows of LED lamps are arranged. Each LED illuminating lamp is installed on the ceiling 13 by a holding unit, which will be described later, and is supplied with power by a wiring, which will be described later.

  In addition, IC tags 18, 19, and 20 are provided corresponding to the holding portions of the ceiling 13 where the LED lighting lamps 2, 4, and 6 are installed, respectively. Similarly, IC tags 18, 19 and 20 are provided corresponding to the LED lighting lamps 12, 14 and 16, respectively, and IC tags 38, 39 and 40 are provided corresponding to the LED lighting lamps 22, 24 and 26, respectively. ing. Two types of information are stored in the IC tags 18, 19, 20, 28, 29, 30, 38, 39 and 40. One is an ID unique to the IC tag, and the other is a control signal channel for controlling the LED lighting. For example, a first channel is set for the IC tags 18, 28 and 38, a second channel is set for the IC tags 19, 29 and 39, and a third channel is set and stored for the IC tags 20, 30 and 40. Yes. Details of the channel setting method will be described later.

  As will be described later, each LED illumination lamp is provided with an IC tag reader / writer. When the LED illumination lamp is attached to the holding portion, channel information is read from the IC tag at the attachment position. Specifically, based on the storage information of the IC tag described above, the LED lighting lamps 2, 12, and 22 have the first channel, the LED lighting lamps 4, 14, and 24 have the second channel, and the LED lighting lamps 6, 16 And 26 read the third channel. In other words, the same channel is read by the LED illuminators in the same row in the vertical direction of FIG. Based on the channel of each LED illumination lamp determined in this way, a signal for controlling the lighting state is transmitted for each channel from the remote controller as will be described later. FIG. 2 (A1) shows a result of transmitting all lighting signals with a duty of 100% through all channels.

  FIG. 2 (B2) corresponds to the state of FIG. 1 (B2) in FIG. 1, and the right side of FIG. Shows lighting. In order to achieve such a lighting state, a full lighting signal with a duty of 100% is transmitted through channel 1, a signal for lighting only the right side 4/6 with a duty of 100% is transmitted through channel 2, and in channel 3, Send off signal. Since transmission of signals of these channels is automatically performed if a desired lighting state is determined, it is not necessary to manually perform transmission operation individually. As described in FIG. 1, the lighting state as shown in FIG. 2 (B2) is suitable for lighting in a lecture hall where the projection screen of the projector is on the left side of FIG. 2 and the audience seat is on the right side.

  FIG. 2 (C2) corresponds to the state of FIG. 1 (C2) in FIG. 1, and gradation lighting is performed so that the LED lighting lamp row of three rows gradually becomes darker toward the right side of FIG. It shows how it is. In order to achieve such a lighting state, a lighting signal is transmitted through the channel 1 so that the right side 5/6 has a duty of 100% and the rest has a duty of 50%, and the right side 4/6 has a duty of 50% through the channel 2. Then, a lighting signal with the remaining duty of 25% is transmitted, and a lighting signal with the right side 4/6 having a duty of 25% and a remaining duty of 13% is transmitted through the channel 3, respectively. Since transmission of signals of these channels is automatically performed if a desired gradation state is determined, it is not necessary to manually perform transmission operation individually. As described in FIG. 1, the lighting state as shown in FIG. 2 (C2) is suitable for lighting a room having a window on the left side of FIG.

  FIG. 3 is a block diagram schematically showing a cross-section of the main part of the first embodiment, and the LED illumination lamp 4 is mainly shown. The same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. A holding part 52 is attached to the ceiling 13, and a wiring 54 runs around the holding part 52. In addition, as described in FIG. 2, the holding portion 52 is provided with IC tags 19, 20, etc. corresponding to the mounting locations of the LED illumination lamps 4, 6, respectively.

  The LED illuminating lamp 4 attached to the holding unit 52 in a replaceable manner has a light emitting unit 58 including a white LED group 56 and is supplied with power from a power supply unit 60 connected to the wiring 54. The white LED group 56 is a generic term for the white LEDs 11 of FIG. Although not shown, the power supply unit 60 supplies necessary voltages to other parts of the LED illumination lamp 4 such as the illumination control unit 62, the wireless communication unit 64, and the IC tag reader / writer 66, respectively. The illumination control unit 62 controls the lighting state of the light emitting unit based on the remote control signal received by the wireless communication unit 64.

  The illumination control unit 62 has a storage unit for storing a program for controlling the LED illumination lamp and necessary data. The remote control signal received by the wireless communication unit 64 is based on infrared communication or WPAN (Wireless Personal Area Network) such as Zigbee (trademark). Further, the IC tag reader / writer 66 communicates with the IC tag 19 when the LED illumination lamp 4 is attached to the holding unit 52, reads the ID unique to the IC tag, and also reads this when the channel is stored. Remember. If no channel is stored in the IC tag 19, it is written from the IC tag reader / writer 66. Details of these functions will be described later.

  The remote control 68 has an operation unit 70 for operating each LED illumination lamp. The remote control control unit 72 instructs the wireless control unit 74 to transmit a remote control signal based on a manual operation by the operation unit 70. The remote control unit 72 has a storage unit for storing a program for remote control and necessary data. The wireless communication unit 64 of each LED illumination light receives a remote control signal from the remote control 68 and transmits it to the illumination control unit 62. The other LED lighting lamps 2, 6 and the like have the same configuration as the LED lighting lamp 4 described above, and are each supplied with power from the wiring 54 and controlled by a remote control signal from the remote control 68.

  FIG. 4 is a block diagram illustrating a detailed configuration of the LED illumination lamp according to the first embodiment, and the same reference numerals are given to the same parts as those in FIG. The white LED group 56 is divided into six groups of a first LED group 82, a second LED group 84, a third LED group 86, a fourth LED group 88, a fifth LED group 90, and a sixth LED group 92. This is to enable partial control of the light emission described in FIG. The power supply unit 60 is divided into two parts, and the first power supply unit 94 supplies power to the first LED group 82, the second LED group 84, and the third LED group 86. On the other hand, the second power supply unit 96 supplies power to the fourth LED group 88, the fifth LED group 90, and the sixth LED group 92.

  The first LED group 82, the second LED group 84, the third LED group 86, the fourth LED group 88, the fifth LED group 90, and the sixth LED group 92 are constant currents via switch elements 98, 100, 102, 104, 106, and 108, respectively. Connected to sources 110, 112, 114, 116, 118 and 120. Thus, if the switch elements 98, 100, 102, 104, 106 and 108 are individually controlled, the first LED group 82, the second LED group 84, the third LED group 86, the fourth LED group 88, the fifth LED group 90 and the The lighting state of the 6LED group 92 can be individually controlled.

  The switch elements 98, 100, 102, 104, 106 and 108 are pulse-driven by PWM control units 122, 124, 126, 128, 130 and 132, respectively, and the duty cycle in each PWM control is changed from 100% to zero. The brightness of the first LED group 82, the second LED group 84, the third LED group 86, the fourth LED group 88, the fifth LED group 90, and the sixth LED group 92 is independently dimmed between full lighting and extinguishing it can.

  The first individual duty control unit 134 controls the duty cycles individually given to the PWM control units 122, 124 and 126. On the other hand, the second individual duty control unit 136 controls the duty cycles individually given to the PWM control units 128, 130, and 132. The first individual duty control unit 134 and the second individual duty control unit 136 are controlled by the illumination control unit 62, respectively. With the above configuration, the first LED group 82, the second LED group 84, the third LED group 86, the fourth LED group 88, the fifth LED group 90, and the sixth LED group 92 are turned on and off based on the remote control signal transmitted from the wireless communication unit 64. And the brightness at the time of lighting can be controlled individually, and lighting control with the middle of the LED lighting as shown in FIG.

  FIG. 5 is a block diagram showing a detailed configuration of the white LED group and the like of the first embodiment, and the same reference numerals are given to the same parts as those in FIG. In FIG. 5, only the portion in charge of the first power supply unit 94 is shown, but the portion in charge of the second power supply unit has the same configuration. As shown in FIG. 5, the configuration related to each white LED group is grouped on one substrate. Specifically, the configuration relating to the first LED group 82 is mounted on the first substrate 138, the configuration relating to the second LED group 84 is mounted on the second substrate 140, and the configuration relating to the third LED group 86 is mounted on the third substrate 142. In other words, lighting and extinguishing of one LED illumination lamp and independent control of brightness at the time of turning on are divided into six for each board.

  Further, as shown in FIG. 5, each LED group in each substrate has a circuit configuration in which four white LED series connections 144 and the like are connected in parallel. Each of the series-connected LEDs 144 and the like is obtained by connecting 12 white LEDs in series. As a result, the first power supply unit 94 has a circuit configuration in which 12 white LEDs are connected in series for 12 columns as a whole in total of three substrates. Note that the individual white LEDs are mechanically arranged in a line in the LED illumination lamp regardless of electrical series connection or parallel connection. As a result, 288 white LEDs are continuously arranged from the first LED group 82 to the sixth LED group 92 in a line in the LED illumination lamp. And as already stated, since white LED of the both ends becomes the arrangement | positioning close | similar to the white LED of the edge part of an adjacent LED illumination light, the line-shaped proof without a boundary is attained.

  FIG. 6 is a block diagram illustrating a detailed configuration of the remote controller 68 of the first embodiment, and the same reference numerals are given to the same parts as those in FIG. In the lighting operation, when the ON button 146 of the operation unit 70 is pressed, the remote control operation unit 72 transmits a remote control signal instructing lighting of 100% duty for all channels from the wireless communication unit 74. Similarly, when the off button 148 is pressed, the remote control operation unit 72 transmits a remote control signal instructing to turn off all channels from the wireless communication unit 74.

  When the split button 150 is pressed, the remote control operation unit 72 transmits a remote control signal for split lighting to each channel from the wireless communication unit 74. Specifically, the LED lighting part corresponding to the right side of the first slider 154 that can be slid in the horizontal direction of the drawing along the guide 152 is turned on at a duty of 100%, and the LED lighting part corresponding to the left side is turned off. A remote control signal is transmitted to each channel. The division of the lit part and the unlit part by the first slider 154 corresponds to (A3), (B1), (B2), (B3), etc. in FIG. Although the slide lever itself can slide steplessly, when the division is in the middle of the LED lighting party, the closest division point among the six divisions is detected by the contact portion provided in the guide 152.

  Further, when the gradation button 156 is pressed, the remote control operation unit 72 transmits a remote control signal for gradation lighting to each channel from the wireless communication unit 74. Specifically, a remote control signal is transmitted to each channel such that the left side of the first slider 154 becomes a gradation starting point that gradually darkens. The gradation control by the first slider 154 corresponds to (C1) or (C2) in FIG.

  In the case of performing control to turn off one side or gradation as described above, the second slider 158 is retracted to the left end. On the other hand, when the second slider 158 is moved from the retracted position into the guide 152, the inside of the first slider 154 and the second slider 158 is turned on at a duty of 100%, and the outside of these is turned off or the first slider 154 is turned off. A remote control signal is transmitted that gradually darkens from the second slider. The lighting state when the gradation button 156 is pressed while the second slider is in the guide 152 corresponds to FIG. 1 (C3). Note that when the first slider 154 or the second slider 158 is slid in the divided or gradation lighting state, a remote control signal for automatically changing the reference point is automatically transmitted in accordance with the slide operation.

  The reverse button 160 is pressed to reverse the lighting relationship as described above with the first slider 154 or the second slider 158 as a reference. Accordingly, when the reverse button 160 is pressed while the second slider 158 is in contrast, the left side of the first slider 154 is lit with a duty of 100%. When the reverse button 160 is pressed while the second slider 158 is in the guide 152, the outer sides of the first slider 154 and the second slider 158 are turned on with a duty of 100%.

  The above is based on the premise that the channel of the LED illuminating lamp has been set. Next, the channel setting performed in the initial stage when the LED illuminating lamp is installed on the ceiling will be described. Channel setting is performed by pressing the set button 162. When the reset button 164 is pressed, the channel setting is reset. Since the set button 162 and the reset button 164 do not normally need to be used after channel setting, they are covered with an operation unit cover 166 to prevent erroneous operation. Since the channel setting once performed is stored in the IC tag, the next time the LED lighting is replaced, the channel corresponding to the position is read from the IC tag by the LED lighting without any setting operation. It is done.

  Since the channel setting to the IC tag is indispensable for the LED illumination light control in the first embodiment, the “channel not set” display 170 is continuously displayed on the display unit 168 as long as this is in the unset state, and the channel setting is prompted. When the setting is completed, the “channel not set” display 170 disappears. When the set button 162 is pressed, a ceiling layout display 172 is displayed on the display unit 168. This corresponds to FIG. 2, and the arrangement of the IC tags installed on the ceiling is indicated by the symbol 174 of the LED illumination lamp. In the vicinity of each symbol, channel setting status displays 176, 178, etc. are displayed. Incidentally, the channel setting state display 176 indicates that “channel 1” is set in the IC tag, and “?” In the channel setting state display 178 indicates that the IC tag is in a channel non-setting state.

  If there is at least one IC tag for which no channel is set, a “next IC tag ID selection” display 180 is displayed on the display unit 168. Since the display unit 68 is a touch panel, when the “next IC tag ID selection” display 180 is pressed, one IC tag in a channel non-set state is selected. Since the relationship between the IC tag position and the ID is not managed when the holding unit 52 is constructed, it is unknown where the selected IC tag is on the ceiling.

  However, in the channel setting state, only the LED illumination lamp located at the position corresponding to the selected IC tag is turned on by pressing the “next IC tag ID selection” display 180 portion, so that the position of the selected IC tag is known. be able to. Then, by looking at the lighting state of the ceiling, if it is found that the selected ID corresponds to the channel setting state display 178, channel 3 can be set in this portion by pressing “3” on the channel designation portion display 182. it can. By this setting operation, “3” set in the channel setting state display 178 blinks. If there is no mistake, pressing the setting state display 178 with “3” blinking will confirm the channel setting of this portion. The above operation is repeated, and when all channel setting status displays change from “?” To channel numbers, the channel setting is completed. Correspondingly, the “next IC tag ID selection” display 180 and the channel designation display 182 disappear. . Further, as described above, the “channel not set” display 170 also disappears.

  FIG. 7 is a flowchart showing the function of the illumination control unit 62 of the LED illumination lamp 4 in the embodiment 1 of FIG. The flow starts by attaching the LED illumination lamp to the holding unit 52. When the flow starts, it is first checked in step S2 whether channel data has been written to the IC tag 19 or not. If not yet written, it is checked in step S4 whether a channel setting signal is received from the remote control. If there is a transmission, the process proceeds to step S6, and the transmitted channel is temporarily stored in the LED illumination lamp itself, and in step S8. The transmitted channel is written in the IC tag, and the process proceeds to step S10.

  On the other hand, if channel data has already been written in the IC tag in step S2, the process proceeds to step S12, the channel is read from the IC tag and stored, and the process proceeds to step S10. If the reception of the channel setting signal cannot be confirmed in step S4, the process proceeds to step S14 to check whether the channel has been stored. If not stored, the process proceeds to step S16, and all channels can be received so as to be able to cope with any channel from which the remote control signal is transmitted, and the process proceeds to step S10. On the other hand, if channel memorized can be detected in step S14, the process directly proceeds to step S10. As described above, the remote control signal can be handled in any state.

  In step S10, it is checked whether a signal lighting signal or any lighting state change signal is received from the remote controller. If there is reception, the process proceeds to step S18, and it is checked whether or not the current channel can be recognized. The state where the own channel can be recognized means a state where the own channel is stored as the LED lighting. If the own channel can be recognized, the process proceeds to step S20, the lighting information addressed to the own channel is read, and the process proceeds to step S22.

  In step S22, it is checked whether or not the read lighting information includes a plurality of remote control signals that need to change the lighting state from the middle part of the LED lighting. If a plurality of signals are included, the process proceeds to step S24, where the individual PWM control of each LED group is instructed, and the process proceeds to step S26. On the other hand, when the own channel cannot be recognized in step S18, the process proceeds to step S28, the maximum duty is set, and in step S30, the common PWM control is instructed to all the LED groups in the LED illumination lamp, and the process proceeds to step S26. . This means that if the own channel cannot be recognized, 100% duty lighting is performed in common for all LED groups regardless of the content of the remote control signal as long as the lighting signal is any kind. In other words, if there is any remote control signal, even if the specific instruction is unknown, priority is given to turning on anyway unless it is a turn-off signal.

  In step S26, it is checked whether a turn-off signal has been received. If there is no reception, the process returns to step S10, and steps S10 and S18 to S26 are repeated to prepare for the next remote control signal. On the other hand, when the reception of the turn-off signal is confirmed in step S26, the process proceeds to step S32, all the LED groups are turned off, and the process returns to step S4. In addition, when the reception of the lighting signal or the change signal is not detected in step S10, the process returns to step S4. In this way, various situation changes can be dealt with by the functions of steps S4 to S10 and steps S14 to S32.

  FIG. 8 is a basic flowchart showing the function of the remote control unit 72 of the remote control 68 in the first embodiment shown in FIG. The flow is started by starting power supply such as battery insertion into the remote control 68. When the flow starts, it is checked in step S42 whether channel setting is completed. If the setting is completed, the process proceeds to step S50. On the other hand, if the completion of channel setting cannot be detected in step S42, the process proceeds to step S46 to instruct the display unit 168 to start displaying “channel not set”, and the channel setting process in step S48 is entered. When the channel setting process ends, the process proceeds to step S50. As will be described later, the channel setting process in step S48 is immediately terminated if the setting start operation is not performed within a predetermined time. In this case, the channel unset state continues. Details of the channel setting process will be described later.

  In step S50, it is checked whether a lighting operation has been performed. If the lighting operation cannot be detected, the flow returns to step S42, and thereafter steps S42 to S50 are repeated to wait for the lighting operation or the channel setting operation as necessary. When a lighting operation is detected in step S50, the process proceeds to step S52, and it is checked whether or not an operation of “divide” or change of division has been performed. If these operations are not detected, the process proceeds to step S54, and it is checked whether or not a “gradation” or gradation changing operation has been performed. If these operations are not detected, the process proceeds to step S56 to check whether the lighting signal has been transmitted. If not transmitted, the process proceeds to step S58 to instruct the transmission of a signal for instructing lighting at the maximum duty in all channels, and the process proceeds to step S60. On the other hand, if it is detected in step S56 that the lighting signal has been transmitted, the process directly proceeds to step S60. Step S56 is required when the flow returns to step S52 and reaches step S56 again as described later.

  On the other hand, when it is detected in step S52 that the “divide” operation or the division change operation has been performed, the process proceeds to step S62 to check whether the channel setting is completed. If the channel setting is completed, the process proceeds to step S64, where “divided” processing for divided lighting is performed, and the process proceeds to step S60. Details of the “division” process will be described later. On the other hand, when the completion of channel setting cannot be detected in step S62, control for each channel cannot be performed, and the process proceeds to step S56. That is, in this case, the “divide” / change operation is invalid.

  If it is detected in step S54 that the “gradation” operation or gradation change operation has been performed, the process proceeds to step S66 to check whether the channel setting has been completed. If the channel setting is complete, the process proceeds to step S68, where "gradation" processing for gradation lighting is performed, and the process proceeds to step S60. Details of the “gradation” process will be described later. On the other hand, when the completion of channel setting cannot be detected in step S66, control for each channel cannot be performed, and the process proceeds to step S56. That is, in this case, the “gradation” / change operation is invalid.

  In step S60, it is checked whether a turn-off operation has been performed. If the operation cannot be detected, the process returns to step S52, and thereafter, step S52 to step S64 are appropriately repeated to deal with various situations. During this time, if no operation is performed, the loop returning to step S52 through step S52, step S54, step S56, and step SS60 is repeated, and no remote control signal is transmitted. There will be no. On the other hand, when a turn-off operation is detected in step S60, transmission of a turn-off signal in all channels is instructed in step S70, and the process returns to step S42. Hereinafter, steps S42 to S70 are repeated as appropriate to correspond to various remote control operations.

  FIG. 9 is a flowchart showing details of the channel setting process in step S48 of FIG. When the flow starts, it is checked in step S72 whether a channel setting start operation by the set button 162 has been performed within a predetermined time. When an operation is detected, the process proceeds to step S74, and a predetermined channel is designated by default. When the channel is not set, the LED illumination lamp can receive all channels in step S16 of FIG. 7, so the default channel may be anything. Next, in step S76, it is checked whether or not an operation has been performed using a tag ID by the “next IC tag ID selection” portion of the display unit touch panel. If an operation is detected, the process proceeds to step S78. On the other hand, when the operation cannot be detected in step S76, the process returns to step S74, and thereafter, steps S74 and S76 are repeated to wait for the operation.

  In step S78, a lighting signal is transmitted to the LED illumination lamp corresponding to the IC tag specified by the ID. As a result, the position of the IC tag is specified. Then, the process proceeds to step S80 to wait for a channel setting operation after confirming the position of the lit LED illumination lamp. When a channel setting operation is detected, the process proceeds to step S82, and a setting confirmation display is performed by blinking the set channel number in the channel setting state display on the display unit 168. Next, in step S84, a confirmation operation is awaited. If a confirmation operation is detected, the process proceeds to step S86.

  In step S86, the channel setting signal determined as described above is transmitted to the LED lighting corresponding to the designated IC tag. This channel setting signal is written to the designated IC tag in step S8 of FIG. In step S88, the channel setting state display on the display unit 168 stops blinking and the determined channel number is displayed.

  Next, in step S90, the set channel is designated, and in step S92, a turn-off signal is transmitted to the set channel. This corresponds to turning off the LED lighting light turned on in step S78, but turning off the light by specifying the channel instead of the IC tag ID to confirm the channel setting. Then, the flow proceeds to step S94 to check whether or not all IC tags have channel settings. If there remains an IC tag for which no channel is set, the process returns to step S74, and step S74 and subsequent steps are repeated for the next IC tag. On the other hand, when it is detected in step S94 that all channels have been set, the flow ends. If a channel setting start operation within a predetermined time cannot be detected in step S72, the flow is immediately terminated.

  FIG. 10 is a flowchart showing details of the “division” process in step S64 of FIG. When the flow starts, slider position information is read in step S102. Next, in step S104, it is checked whether or not there is an LED illumination lamp for which a plurality of types of lighting signals are instructed. This corresponds to a check of whether or not the slider is in a position that changes the lighting state in the middle of any of the LED lighting lamps, and can be determined from the read information obtained in step S102. In the case of the “division” process, “plural types” are a turn-on signal and a turn-off signal, and corresponds to a case where a part of one LED illumination light is turned on and a part is turned off. If it is detected in step S104 that this is the case, the process proceeds to step S106, and one channel instructing a plurality of types of lighting signals is selected.

  Next, in step S108, an independent lighting or extinguishing signal is created for each of the six LED groups in the selected channel. In step S110, the maximum duty is set for the LED group to be lit. Then, the process proceeds to step S112, and it is checked whether or not the processing from step S106 to step S110 has been completed for all channels instructing a plurality of types of lighting signals. If there is a processing channel, the process returns to step S106, and the same processing is performed for the next channel. On the other hand, if the processing is completed for all the channels in step S112, the process proceeds to step S114. If no LED illuminating lamp for which a plurality of types of lighting signals are instructed in step S104, the process immediately proceeds to step S114.

  In step S114, a single type of remote control signal, that is, all the channels that are instructed to turn on or off are selected. In step S116, a turn-on or turn-off signal is generated for each channel for these channels. In step S118, the maximum duty is set for the channel to be lit, and the process proceeds to step S120.

  In step S120, it is checked whether or not a reversal operation has been performed. If an operation is detected, the process proceeds to step S122 to perform a process of reversing the creation signal, and the process proceeds to step S124. On the other hand, when the reversal operation is not detected in step S120, the process directly proceeds to step S124. In step S124, the remote control signal created as described above is transmitted on each channel, and the flow ends.

  FIG. 11 is a flowchart showing details of the “gradation” process in step S68 of FIG. When the flow starts, slider position information is read in step S132. Next, in step S134, it is checked whether or not there is an LED illumination lamp for which a plurality of types of lighting signals are instructed. In the case of the “gradation” process, “plural types” corresponds to lighting signals having different duties as well as lighting signals and extinguishing signals. If it is detected in step S134 that this is the case, the process proceeds to step S136, and one channel instructing a plurality of types of lighting signals is selected.

  Next, in step S138, an independent lighting or extinguishing signal is created for each of the six LED groups in the selected channel. Further, in step S140, a designated duty is set for each of the LED groups to be lit. Then, the process proceeds to step S142, and it is checked whether or not the processing from step S106 to step S110 has been completed for all channels instructing a plurality of types of lighting signals. If there is an unprocessed channel, the process returns to step S136, and the same process is performed for the next channel. On the other hand, if the processing is completed for all the channels in step S142, the process proceeds to step S144. If no LED illuminating lamp for which a plurality of types of lighting signals are instructed in step S134, the process immediately proceeds to step S144.

  In step S44, one channel instructing a single type of lighting signal is selected. Next, in step S146, it is checked whether or not an extinction signal should be set for the selected channel. If not, the process proceeds to step S148 to create a lighting signal for the selected channel, set the designated duty, and proceed to step S150. On the other hand, when it is detected in step S146 that a turn-off signal should be set for the selected channel, the process proceeds to step S152 to create a turn-off signal, and the process proceeds to step S150. In step S150, it is checked whether or not the processing from step S144 to step S148 or step S152 has been completed for all channels instructing a single type of lighting signal. If there is an unprocessed channel, the process returns to step S144, and the same process is performed for the next channel. On the other hand, if all the channels have been processed in step S150, the process proceeds to step S154.

  In step S154, it is checked whether or not a reversal operation has been performed. If an operation is detected, the process proceeds to step S156 to perform a process of reversing the creation signal, and the process proceeds to step S124. On the other hand, when no reversal operation is detected in step S154, the process directly proceeds to step S158. In step S158, the remote control signal created as described above is transmitted on each channel, and the flow ends.

  FIG. 12 is a block diagram showing a detailed configuration of the LED lighting in Example 2 of the lighting device according to the embodiment of the present invention. The external view of the lighting state of the LED lighting of Example 2 and the layout when the lighting device is installed on the ceiling are the same as those of Example 1 of FIGS. A block diagram schematically showing a cross section of the main part is also common to the first embodiment of FIG. Furthermore, since there are many common parts with the detailed configuration of the LED illumination lamp in the first embodiment shown in FIG.

  The LED illuminating lamp of Example 2 shown in FIG. 12 is different from Example 1 of FIG. 4 in that Example 1 was independently PWM-controlled in units of LEDs, whereas Example 2 This is the point that PWM control is independently performed in series connection units. As a result, the LED lighting can be controlled independently for each of the 24 sections, and the division between lighting and extinguishing can be changed more finely and gradation can be changed more continuously. This can be better understood by comparing the first substrates 138 in FIG. 5 of the first embodiment and FIG. 12 of the second embodiment.

  Specifically, the white LED series connections 302, 304, 306 and 308 forming the first LED group are connected to the constant current sources 318, 320, 322 and 324 via the switch elements 310, 312, 314 and 316, respectively. ing. Thus, if the switch elements 310, 312, 314, and 316 are individually controlled, the lighting states of the white LED series connections 302, 304, 306, and 308 can be individually controlled.

  Switch elements 310, 312, 314 and 316 are pulse-driven by PWM control units 326, 328, 330 and 332, respectively, and are fully lit by changing the duty cycle in each PWM control from 100% to zero. The brightness of the white LED series connections 302, 304, 306, and 308 can be dimmed independently from the time of turning off to turning off. The first individual duty control unit 134 controls the duty cycles individually given to the PWM control units 326, 328, 330 and 332.

  Since the second substrate 140 and the third substrate 142 supplied with power from the first power supply unit 94 and controlled by the first individual duty control unit 134 have the same configuration as the first substrate 138, illustration is omitted for simplicity. In addition, since the other three bases supplied with power from the second power supply unit 96 and controlled by the second individual duty control unit 136 have the same configuration, only the fourth substrate 334 is illustrated, and the others are omitted and the fourth. The detailed configuration of the substrate 334 is also omitted.

  FIG. 13: is a block diagram which shows the detailed structure of the LED illumination light in Example 3 of the illuminating device which concerns on embodiment of this invention. The external view of the lighting state of the LED lighting lamp of the third embodiment and the layout when the lighting device is installed on the ceiling are also common to the first embodiment of FIGS. A block diagram schematically showing a cross section of the main part is also common to the first embodiment of FIG. Furthermore, since there are many common parts with the detailed configuration of the LED illumination lamp in the first embodiment shown in FIG.

  The LED illuminating lamp of the third embodiment shown in FIG. 13 is different from the first embodiment of FIG. 4 in that the PWM of the first embodiment is independently controlled for each LED group, whereas in the third embodiment, the power supply unit is different. Thus, PWM control is performed independently. As a result, the LED illumination lamp is divided into two sections and can be controlled independently. In such a third embodiment, although the division is rough, PWM is performed in units of power supply units, so the configuration is very simple, and dimming can be performed independently in units of half the length of the LED lighting lamp. The advantages of the present invention can also be enjoyed. This can be better understood by comparing FIG. 4 of the first embodiment and FIG. 13 of the third embodiment.

  More specifically, the first LED group 402, the second LED group 404, and the third LED group 406 fed by the first power supply unit are grouped in parallel and connected to the constant current source 410 via the switch element 408. . On the other hand, the fourth LED group 412, the fifth LED group 414, and the sixth LED group 416 fed by the second power supply unit 96 are also grouped in parallel and connected to the constant current source 420 via the switch element 418. Thus, if the switch elements 408 and 418 are individually controlled, the lighting states of the LED group fed from the first power supply unit 94 and the LED group fed from the second power supply unit 96 can be individually controlled.

  The switch elements 408 and 418 are pulse-driven by PWM control units 422 and 424, respectively, and the duty cycle of each PWM control is changed from 100% to zero to change the LED group between full lighting and extinguishing. The brightness can be dimmed independently for each power supply unit. The individual duty control unit 426 controls the duty cycles individually given to the PWM control units 422 and 424.

  The present invention provides a lighting device suitable for ceiling lighting and wall lighting.
