Description
Technical Field
The present invention relates to a power supply device, an illumination lamp, and an illumination device, and more particularly, to a power supply device used for an LED lamp that can be attached to a glow starter type illumination fixture, and an LED lamp and an LED illumination device using the power supply device.
Background
The conventional fluorescent lamp lighting systems are roughly classified into 3 types, namely, a glow starter type, a quick start type, and a high-frequency lighting exclusive type (inverter type). Among them, the glow starter type is widely used because it enables a lighting fixture including a lighting device to be easily designed and is inexpensive. In the glow starter type lighting system, a dedicated lamp such as a straight tube type FL tube or a ring type FCL tube, and a glow starter are used.
In recent years, there has been proposed a method of using an LED lamp instead of a fluorescent lamp in a glow starter type lighting device (for example, patent documents 1 to 3). In this method, the user can easily replace the fluorescent lamp with the LED lighting device simply by replacing the fluorescent lamp with the LED lamp. Therefore, the method is considered to be increasingly popular. On the other hand, non-patent document 1 defines international standards for a method of mounting an LED lamp to a glow starter type lighting fixture.

Disclosure of Invention
None of the LED lighting devices disclosed in patent documents 1 to 3 is premised on the international standard disclosed in non-patent document 1. According to international standard (IEC 62776Edition 1.02014-12), when an LED lighting device is configured by a glow starter type lighting device, a fluorescent lamp and an LED lamp are replaced, and a glow starter and a dummy starter (dummy starter) are replaced. In this method, it is easy to forget to replace the glow starter and the dummy starter. When the glow starter and the dummy starter are forgotten to be replaced, a high voltage may be applied to the LED lamp. At this time, the lighting device may have a high temperature.
The present invention has been made to solve the above problems, and an object of the present invention is to obtain a power supply device 1 capable of protecting an illumination device at a high temperature in a glow starter type illumination device in a case where a fluorescent lamp is replaced with an illumination lamp equipped with a semiconductor light emitting element and the glow starter and a dummy starter are not replaced.
A second object of the present invention is to provide an illumination lamp which can protect the illumination device at a high temperature when a fluorescent lamp is replaced with an illumination lamp having a semiconductor light emitting element mounted thereon and the glow starter and a dummy starter are not replaced in a glow starter type illumination device.
A third object of the present invention is to provide a glow starter type lighting device having a protection function at a high temperature when a fluorescent lamp is replaced with an illumination lamp having a semiconductor light emitting element mounted thereon and the glow starter and a dummy starter are not replaced.
A 4 th object is to obtain a power supply device that can urge a user to replace a glow starter and a dummy starter in a glow starter type lighting device.
A 5 th object is to obtain an illumination lamp that can urge a user to replace a glow starter and a dummy starter in a glow starter type illumination device.
A fourth object of the present invention is to provide a glow starter type lighting device, wherein the glow starter is provided with a dummy starter.
A 7 th object is to obtain a power supply device capable of protecting an illumination lamp at a high voltage when a fluorescent lamp is replaced with an illumination lamp having a semiconductor light-emitting element mounted thereon and the glow starter and a dummy starter are not replaced in a glow starter type illumination device.
An object 8 is to obtain an illumination lamp having a protection function under a high voltage in a glow starter type illumination device in which a fluorescent lamp is replaced with an illumination lamp having a semiconductor light emitting element mounted thereon and the glow starter and a dummy starter are not replaced.
A 9 th object is to obtain an illumination device of a glow starter type, which can protect an illumination lamp at a high voltage when a fluorescent lamp is replaced with an illumination lamp having a semiconductor light emitting element mounted thereon and the glow starter and a dummy starter are not replaced.
The power supply device of the present invention is a power supply device for an illumination lamp equipped with a semiconductor light emitting element, which is mounted on a glow starter type illumination apparatus, and includes: an input having a 1 st input and a 2 nd input; a power supply circuit connected to the input terminal and generating a voltage for lighting the semiconductor light emitting element; and the fuse is connected between the input end and the power circuit.
Further, a power supply device according to the present invention is a power supply device for an illumination lamp equipped with a semiconductor light emitting element, which is mounted on a glow starter type illumination fixture, and includes: an input having a 1 st input and a 2 nd input; a power supply circuit connected to the input terminal and generating a voltage for lighting the semiconductor light emitting element; and a capacitor, between the input terminal and the power supply circuit, one end of the capacitor is connected with the 1 st input terminal, and the other end of the capacitor is connected with the 2 nd input terminal.
Further, a power supply device according to the present invention is a power supply device for an illumination lamp equipped with a semiconductor light emitting element, which is mounted on a glow starter type illumination fixture, and includes: an input having a 1 st input and a 2 nd input; a power supply circuit connected to the input terminal and generating a voltage for lighting the semiconductor light emitting element; and a protection unit having one end connected to the 1 st input terminal and the other end connected to the 2 nd input terminal between the input terminal and the power supply circuit, the protection unit having a resistance value which decreases when a voltage applied between the 1 st input terminal and the 2 nd input terminal is higher than a threshold value.
In the power supply device of the present invention, a fuse is provided between the input terminal and the power supply circuit. The fuse is blown when the power supply apparatus becomes high temperature. At this time, the connection of the input terminal and the power supply circuit is cut off. Therefore, the supply of power to the power supply device is stopped. As a result, the application of the high voltage to the power supply device is stopped, and the temperature rise of the lighting device can be suppressed. Therefore, the lighting device can be protected at high temperature.
In the power supply device of the present invention, a capacitor is provided between the input terminal and the power supply circuit. The input impedance of the power supply device is adjusted by the capacitance of the capacitor. In the lighting apparatus, the voltage applied to the glow starter is adjusted by adjusting the input impedance of the power supply device in a state where the glow starter and the dummy starter are not replaced. Therefore, the voltage applied to the glow starter can be adjusted by adjusting the capacitance of the capacitor. If the voltage applied to the glow starter is adjusted to a voltage at which the glow starter alternately repeats a discharge state and an on state, the lighting lamp alternately repeats lighting and extinguishing. At this time, the user can be notified that the glow starter is not replaced by the blinking of the illumination lamp. Therefore, the user can be prompted to replace the glow starter and the dummy starter.
In the power supply device of the present invention, a protection unit is connected between the 1 st input terminal and the 2 nd input terminal between the input terminal and the power supply circuit. When a voltage higher than a threshold value is applied to the input terminal, the resistance value of the protection portion becomes low. Therefore, when a high voltage is applied to the input terminal, the resistance value of the protection portion decreases, and the high voltage component is bypassed. As a result, it is possible to prevent a high voltage from being applied to the power supply circuit. Therefore, the lighting device can be protected at a high voltage.

Detailed Description
A power supply device, an illumination lamp, and an illumination device according to embodiments of the present invention will be described with reference to the drawings. The same or corresponding components are denoted by the same reference numerals, and redundant description thereof may be omitted.
Fig. 1 is a block diagram of a fluorescent lighting system 88 of the glow starter type. The fluorescent lighting system 88 is of the glow starter type. In the fluorescent lighting system 88, the filament of the fluorescent lamp 900 is preheated and lighted by using the glow starter 820 as a starting means. In the fluorescent lighting system 88, electric power is supplied from the external power supply 50 to the glow starter type lighting device 80. The external power supply 50 is a commercial ac power supply.
The glow starter lighting device 80 is configured by attaching a fluorescent lamp 900 and a glow starter 820 to a glow starter lighting fixture 100. The glow starter type lighting fixture 100 includes a lighting device 110, a socket 851, and a glow socket 841. The fluorescent lamp 900 is installed in the socket 851. The socket 851 is a socket having a shape suitable for connection of the fluorescent lamp 900. In addition, a glow starter 820 is installed in the glow socket 841. The glow socket 841 is a socket of a shape suitable for the connection of the glow starter 820. In the present embodiment, the lighting fixture 100 includes a fixture having a shape of a trough, a cover, a reverse-fuji type (for a 2-lamp), or a built-in type.
In the fluorescent lighting system 88, the external power supply 50, the glow starter type lighting device 110, and the fluorescent lamp 900 form a series circuit. The glow starter 820 is connected in parallel to the fluorescent lamp 900.
The lighting device 110 is a magnetic stabilizer. Magnetic stabilizers are also known as magnetic loop stabilizers or as copper iron type stabilizers. The lighting device 110 has a specification for lighting the fluorescent lamp 900 in the glow starter type fluorescent lighting system 88. The lighting device 110 includes a choke coil having a structure in which a copper winding is wound around a core through which magnetism passes. The fluorescent lamp 900 starts to discharge due to the electric characteristics of the choke coil. In addition, the choke coil stably maintains the discharge state of the fluorescent lamp 900. In the lighting device 110, the discharge current of the glow starter 820 can be controlled by adjusting the inductance of the choke coil.
The fluorescent lamp 900 is a glow starter type fluorescent lamp. In the present embodiment, the fluorescent lamp 900 is a straight tube fluorescent lamp.
The glow starter 820 is a current path for providing a preheat current to the filaments of the fluorescent lamp 900. The glow starter 820 has a function of generating a discharge voltage between filaments included in the fluorescent lamp 900. Glow starter 820 is provided with a pair of terminals 822. The terminal pair 822 includes a 1 st terminal 822a and a 2 nd terminal 822 b. Electrodes are connected to the 1 st terminal 822a and the 2 nd terminal 822 b. At least one of the electrodes connected to the 1 st terminal 822a and the 2 nd terminal 822b is a movable electrode.
The glow starter 820 is set with a discharge start voltage V as a component specificationDp. If a voltage exceeding a discharge start voltage V is applied between the 1 st terminal 822a and the 2 nd terminal 822bDpVoltage between terminals VDThen a discharge is generated between the terminal pair 822. At this time, the glow starter 820 is in a discharge state. The movable electrode deforms due to a temperature rise associated with the discharge. As a result, the electrodes connected to the terminal pair 822 come into contact with each other. At this time, the glow starter 820 is turned on. In the on state, no discharge is generatedElectricity, the temperature of the electrodes drops. Due to the temperature drop, the movable electrode deforms in the opposite direction to the rise in temperature. As a result, the electrodes connected to the terminal pair 822 are separated from each other again.
Next, the fluorescent lamp lighting system 88 is explained. The fluorescent lighting system 8 operates by supplying power from the external power supply 50 to the glow starter type lighting device 80. When ac power is supplied from the external power supply 50, the glow starter 820 is in a discharge state. Due to the temperature rise accompanying the discharge, the electrodes connected to the terminal pair 822 come into contact with each other. As a result, the glow starter 820 is turned on. At this time, the fluorescent lighting system 88 forms a closed loop. Therefore, a current flows through the filaments of the fluorescent lamp 900, and the filaments are preheated.
At this time, the glow starter 820 is in an on state, and a temperature drop occurs. Accordingly, the electrodes connected to the terminal pair 822 are separated from each other again. If the electrodes are separated from each other, the circuit becomes open in the fluorescent lighting system 88. At this time, a high back electromotive force is generated at both ends of the lighting device 110. The back emf is on the order of a thousand to a few hundred volts. This back emf becomes a trigger and the fluorescent lamp 900 begins to discharge between the preheated filaments. As a result, the fluorescent lamp 900 is turned on.
The fluorescent lamp 900 continues to discharge between the filaments, and in the lit state, the voltage between the terminal pair 822 is lower than the discharge start voltage VDp. At this time, the glow starter 820 is in a stopped state in which it is not in a discharge state nor in a contact state.
Fig. 2 is a block diagram of the LED lighting system 11 according to embodiment 1 of the present invention. The LED lighting system 11 is configured by detaching the fluorescent lamp 900 and the glow starter 820 from the fluorescent lighting system 88, and attaching the illumination lamp 300 and the dummy starter 120. In the LED lighting system 11, power is supplied from the external power supply 50 to the lighting device 10. The lighting device 10 includes a glow starter type lighting fixture 100, an illumination lamp 300, and a virtual starter 120.
The illumination lamp 300 is mounted with a semiconductor light emitting element. In this embodiment mode, the semiconductor light emitting element is an LED element. The dummy starter 120 has a function of turning on the glow socket 841. The LED lighting system 11 is configured by connecting an external power supply 50, a power supply device 320 for supplying lighting power to the semiconductor light emitting elements, the lighting device 110, and the dummy starter 120 in series.
The illumination lamp 300 is provided with a socket attachable to the socket 851. The base includes a 1 st base 350 connected to the external power supply 50 side and a 2 nd base 356 connected to the lighting device 110 side. The illumination lamp 300 is fixed to the illumination appliance 100 through the 1 st socket 350 and the 2 nd socket 356. The 1 st socket 350 includes a terminal pair 351. The 2 nd socket 356 is provided with a terminal pair 357. The pair of terminals 351, 357 are connected to the socket 851.
In the present embodiment, the illumination lamp 300 is a straight tube LED lamp. The illumination lamp 300 includes a power supply device 320, a light emitting unit 310, a wiring unit, and a housing unit. The power supply device 320 generates a voltage for lighting the semiconductor light emitting element. The light emitting unit 310 is mounted with a semiconductor light emitting element. The wiring portion includes a power supply wiring member 332 and a light source wiring member 333. The housing portion includes a cover 340, a 1 st light socket 350, and a 2 nd light socket 356. The power supply device 320 and the light emitting unit 310 are disposed inside the housing. The cover 340 has light-transmitting properties.
Power is supplied from the external power supply 50 to the power supply device 320 via the terminal pair 351. Therefore, the 1 st socket 350 becomes a power supply socket. The terminal pair 357 provided in the 2 nd socket 356 is electrically connected through the fuse 336. Therefore, the terminal pair 357 has a function of conducting between the lighting device 110 and the virtual starter 120. Further, the blowing characteristic of the fuse 336 is selected according to the characteristic of the lighting device 110. For example, in the illumination lamp 300 connected to the lighting device 110 suitable for the fluorescent lamp 900 having a length of 2ft, the fuse 336 having a fusing current of about 160mA may be selected. For example, in the illumination lamp 300 connected to the lighting device 110 suitable for the fluorescent lamp 900 having a length of 4ft, the fuse 336 having a fusing current of about 200mA may be selected.
The dummy starter 120 is installed to conduct the glow socket 841. The dummy starter 120 includes a terminal 122 corresponding to the glow plug 841. The terminals 122 include a 1 st terminal 122a and a 2 nd terminal 122 b. The 1 st terminal 122a is connected to the 1 st base 350 side of the illumination lamp 300. The 2 nd terminal 122b is connected to the 2 nd socket 356 side of the illumination lamp 300.
Fig. 3 is a circuit block diagram (1) of an illumination lamp according to embodiment 1 of the present invention. The terminal pair 351 provided in the 1 st base 350 is connected to the input terminal 329 provided in the power supply device 320 via the power supply wiring member 332. Therefore, the power supply device 320 receives ac power from the input end 329. Ac power is input to the power supply circuit 330 via the input section 323.
The power supply circuit 330 generates a voltage for lighting the semiconductor light emitting element. The ac power input to the power supply circuit 330 is input to the rectifier 324. The rectifying unit 324 converts the ac power into dc power. The output power of the rectifying unit 324 is smoothed by the smoothing unit 325 and then input to the output unit 326. The input power and the output power of the output unit 326 are detected by the detection unit 328. The controller 327 controls the output unit 326 based on the power value detected by the detector 328. As a result, constant current control is performed so that the output current of the output unit 326 becomes constant.
According to the above, a constant current is output in the power supply circuit 330. Therefore, the power supply device 320 becomes a constant current circuit. Power is supplied from the power supply device 320 to the light emitting section 310 as a constant current load via the light source wiring member 333. As a result, dc power for lighting is supplied to the semiconductor light emitting element mounted on the light emitting section 310. The power supply device 320 is an AC-DC conversion circuit that converts AC power input from the external supply power source 50 into DC power and outputs the DC power to the light emitting unit 310.
Fig. 4 is a circuit block diagram (2) of the illumination lamp according to embodiment 1 of the present invention. The input end 329 includes a 1 st input end 329a and a 2 nd input end 329 b. The input unit 323 includes a fuse. The fuse is connected between the input 329 and the power circuit 330. The fuse includes a 1 st fuse 323a and a 2 nd fuse 323 b. The 1 st fuse 323a is connected between the 1 st input terminal 329a and the power supply circuit 330. The 2 nd fuse 323b is connected between the 2 nd input terminal 329b and the power supply circuit 330.
The input unit 323 includes a capacitor 323c between the fuse and the power supply circuit 330. The capacitor 323c has one end connected to the 1 st input terminal 329a and the other end connected to the 2 nd input terminal 329 b. The input unit 323 includes a varistor 323d between the capacitor 323c and the power supply circuit 330. The varistor 323d has one end connected to the 1 st input end 329a and the other end connected to the 2 nd input end 329 b. The rectifying unit 324 includes a diode 324 a.

Fig. 5D is a left side view of illumination lamp 300 according to embodiment 1 of the present invention. Fig. 5E is a right side view of the illumination lamp according to embodiment 1 of the present invention. The 1 st base 350 includes a terminal pair 351 and a frame 352. The 2 nd socket 356 includes a pair of terminals 357 and a frame 358. The frames 352 and 358 have a cylindrical shape.

In addition, the terminal pair 351, 357 can be a terminal-shaped member corresponding to the socket 851. As the terminal pair 351, 357, a G13 type or a GX16 type shown in fig. 5A to E can be used.
Fig. 6A is a plan view showing the structure of illumination lamp 300 according to embodiment 1 of the present invention. Fig. 6B is a front view showing the structure of illumination lamp 300 according to embodiment 1 of the present invention. Fig. 6C is a bottom view showing the structure of illumination lamp 300 according to embodiment 1 of the present invention. Fig. 6D is a left side view showing the structure of illumination lamp 300 according to embodiment 1 of the present invention. Fig. 6E is a right side view showing the structure of illumination lamp 300 according to embodiment 1 of the present invention. In fig. 6A to E, a part of the housing portion is omitted for convenience. The power supply device 320 includes a power supply substrate 322 and a circuit component 321. The circuit component 321 is mounted to the power supply substrate 322. In addition, a wiring pattern is formed on the power supply substrate 322. The wiring pattern and a part of the circuit member 321 constitute a constant current circuit.
The power supply substrate 322 is disposed such that a normal direction of the power supply substrate 322 is perpendicular to a longitudinal direction of the illumination lamp 300. In a state where the power supply device 320 is held by the housing 352, a part thereof is housed inside the 1 st base 350. The portion of power supply device 320 exposed from socket No. 1 350 is housed inside cover 340. In this configuration, the area of the power supply substrate 322 can be increased compared to the case where the power supply device 320 is disposed so as to be housed in the 1 st socket 350. Therefore, the space between the circuit components 321 disposed on the power supply substrate 322 can be secured wide. Therefore, heat dissipation is improved, and the generation of operating heat of the power supply device 320 can be dispersed.
In the illumination lamp 300, the housings 352 and 358 and the cover 340 may be made of resin. In the present embodiment, heat generation of the power supply device 320 is suppressed by increasing the area of the power supply substrate 322. Therefore, the amount of heat to which the resin portion is subjected can be suppressed. Also, by increasing the area of the power supply substrate 322, the interval between the components is widened. Accordingly, insulation resistance against high voltage noise that enters from the outside of the illumination lamp 300 is improved.
The light emitting section 310 includes a semiconductor light emitting element 311, a light source substrate 312, and a base 313. The light source substrate 312 is disposed adjacent to the power substrate 322. The light source substrate 312 is disposed on the surface of the base 313. The base 313 is a heat sink having a heat radiation function. The semiconductor light emitting element 311 is mounted on the surface of the light source substrate 312. The light emitting unit 310 is housed in the cover 340 in a state of being held by the inner wall of the cover 340.
The light source substrate 312 may be made of paper phenol, glass, metal, or a mixture of any of these materials. Further, the light source substrate 312 may be either a rigid type or a flexible type. In this embodiment, the semiconductor light emitting element 311 is an LED element. In contrast, the semiconductor light-emitting element 311 may be an organic EL element or a semiconductor laser.

Therefore, by attaching the dummy starter 120 to the glow socket 841, the glow socket 841 can be electrically conducted.

Fig. 10 is a block diagram of a lighting system 77 in which a glow starter 820 and an illumination lamp 300 according to embodiment 1 of the present invention are attached to a glow starter type lighting fixture 100. In the retrofit construction from the glow starter type lighting apparatus 80 to the lighting apparatus 10 according to the present embodiment, it is necessary to replace the fluorescent lamp 900 and the illumination lamp 300, and replace the glow starter 820 and the dummy starter 120. In this refurbishment, it is easy to forget to replace the glow starter 820 and the virtual starter 120.
Fig. 10 shows the lighting device 70 in a state where the glow starter 820 is not replaced and the fluorescent lamp 900 and the illumination lamp 300 are replaced. In general, in a lighting apparatus in which an LED lamp is installed without replacing a glow starter, the LED lighting apparatus may be damaged due to a high-voltage counter electromotive force generated by the glow starter.
Here, as shown in fig. 4, the power supply device 320 according to the present embodiment includes a varistor 323 d. Varistors are also known as variable resistors (varistors). The varistor 323d has a very large resistance in the case where the voltage applied across both ends is lower than the threshold value. However, when the voltage applied to both ends is higher than the threshold value, the resistance becomes small.
The varistor 323d has one end connected to the 1 st input end 329a and the other end connected to the 2 nd input end 329 b. If the glow starter 820 generates a high voltage, a high voltage is applied to the input 329 via the terminal pair 351. At this time, a voltage higher than the threshold value is applied to both ends of the varistor 323 d. Therefore, the varistor 323d has low resistance. As a result, the varistor 323d is bypassed, and a high voltage can be prevented from being applied to the power supply circuit 330 and the light emitting unit 310.
Therefore, in the power supply device 320 according to the present embodiment, the power supply circuit 330 and the semiconductor light emitting element 311 can be protected at a high voltage without replacing the glow starter 820 as in the lighting system 77. Therefore, the lighting device 70 can be protected from damage caused by a high voltage.
In the lighting device 10 in which the dummy actuator 120 is accurately mounted, an excessive voltage may be applied from the outside of the illumination lamp 300 or the lighting device 10. The lighting device 10 can be protected even at such a high voltage by the varistor 323 d. The varistor 323d has a characteristic of bypassing a voltage of 500V to 1500V. The varistor 323d has a voltage resistance of 500V to 1500V.
In the present embodiment, the power supply device 320 includes the varistor 323 d. In contrast, the varistor 323d may be replaced with a protection unit having a protection function under high voltage. The protection unit has a function of decreasing the resistance value when the voltage applied between the 1 st input terminal 329a and the 2 nd input terminal 329b is higher than the threshold value. The protection unit can use a gas-tube arrester (gasstub arrester), a microgap arrester, or a silicon-based surge absorber.
As shown in fig. 4, the power supply device 320 includes a capacitor 323 c. The capacitor 323c adjusts the input impedance of the power supply device 320. In the lighting device 70, the ac voltage V supplied from the external power supply 50ACThe voltage is divided by the input impedance of the lighting device 110, the glow starter 820, and the illumination lamp 300. The capacitor 323c is connected to a pair of electrodes 822 of the glow starter 820 and has a discharge start voltage V applied therebetweenDpThe capacitance value is selected in the manner of the voltage. The voltage applied between the electrodes connected to the terminal pair 822 is set to 150V to 180V.
Fig. 11 is a timing chart (1) showing the operation of the illumination system 77 shown in fig. 10. VAC[V]Which represents an ac voltage input to the lighting device 70 from the external power supply 50. T isG[℃]Showing the temperature change of the movable electrode of the glow starter 820. VD[V]Representing the voltage between the electrodes of the glow starter 820. VIN[V]An ac voltage input to the input terminal 329 of the power supply device 320 is shown. I isLED[A]The current flowing through the light emitting unit 310 as a load circuit is shown.
At time t0, if ac power is supplied from the external power supply 50 to the lighting device 70, a voltage is applied between the electrodes connected to the pair of terminals 822 of the glow starter 820. Here, as described above, the capacitor 323c is provided so as to apply the voltage V exceeding the discharge start voltage V between the electrodes of the glow starter 820DpThe capacitance value is selected in the manner of the voltage. Accordingly, discharge starts between the electrodes provided in the glow starter 820 (mode 1). The temperature of the movable electrode provided in the glow starter 820 rises with the discharge. In mode 1, since no lighting power is supplied to the light emitting unit 310, the illumination lamp 300 is turned off.
The movable electrode of the glow starter 820 deforms with an increase in temperature. As a result, at time t1, the movable electrode reaches a predetermined amount of deformation, and the electrodes provided in the glow starter 820 come into contact with each other (mode 2). As a result, the glow starter 820 is turned on. In mode 2, the lighting system 77 constitutes a closed loop. At this time, lighting power is supplied to the light emitting unit 310, and the illumination lamp 300 is turned on.
In mode 2, the electrodes of the glow starter 820 are in contact with each other, and no discharge is performed. Accordingly, the temperature of the electrodes provided in the glow starter 820 decreases. As a result, the movable electrodes are deformed in the reverse direction, and the electrodes are separated from each other again. Therefore, the lighting device 70 shifts to mode 1 again. Thereafter, the illumination system 77 repeats pattern 1 and pattern 2 alternately.
In this way, if the power supply device 320 in the present embodiment is used, the illumination lamp 300 is alternately repeatedly turned on and off (hereinafter also referred to as blinking) without replacing the glow starter 820. In the case where the glow starter 820 is not replaced, the illumination lamp 300 does not normally continue the lighting state, but repeatedly (not normally) blinks. Therefore, the user can be notified that the lighting device 70 is not properly installed. Therefore, the user can be prompted to replace the glow starter 820 and the dummy starter 120. Here, the user in the present embodiment includes a professional construction worker having professional knowledge or qualification, in addition to a general consumer.
The temperature rise rate of the movable electrode is determined by the voltage applied between the electrodes provided in the glow starter 820. Therefore, the cycle of mode 1 and mode 2 can be adjusted by adjusting the capacitance value of the capacitor 323 c. The cycle of the mode 1 and the mode 2 is adjusted in a range of several seconds to ten seconds so that the flickering of the illumination lamp 300 is easily recognized by the user. Further, if the capacitance value of the capacitor 323c is adjusted to about 0.15 μ F, the illumination lamp 300 repeats blinking, which is easy to recognize.
When the mode 1 and the mode 2 are switched, a high-voltage back electromotive force is generated at both ends of the lighting device 110. In the present embodiment, the power supply device 320 includes a varistor 323 d. Therefore, the circuit member 321 and the semiconductor light-emitting element 311 constituting the power supply circuit 330 can be protected at a high voltage.
In the lighting device 10 in which the virtual starter 120 is accurately mounted, high-frequency noise may flow from the outside of the illumination lamp 300 or the lighting device 10. The capacitor 323c has a function of bypassing the extraneous noise. Therefore, inflow of external noise to the power supply circuit 330 is suppressed. Therefore, malfunction of the constant current circuit can be prevented.
Fig. 12 is a timing chart (2) showing the operation of the illumination system 77 shown in fig. 10. In the lighting system 77 in which the glow starter 820 is not replaced, a high-voltage back electromotive force may be generated across the lighting device 110. Due to the high voltage, the temperature of the lighting device 70 may increase.
Here, as shown in fig. 4, the power supply device 320 of the present embodiment includes a 1 st fuse 323a and a 2 nd fuse 323 b. When the temperature of the power supply device 320 rises to reach a predetermined temperature, the 1 st fuse 323a or the 2 nd fuse 323b blows. As shown in fig. 4, the 1 st fuse 323a and the 2 nd fuse 323b are connected between the input terminal 329 and the power supply circuit 330. Accordingly, the 1 st fuse 323a or the 2 nd fuse 323b is blown, thereby stopping the power supply to the power supply circuit 330. Therefore, the operation of the power supply device 320 is stopped. As a result, the temperature rise of the lighting device 70 is suppressed.
As described above, when the power supply device 320 according to the present embodiment is used, the illumination lamp 300 blinks in the illumination system 77 in which the glow starter 820 is not replaced. The back electromotive force at the time of switching between the mode 1 and the mode 2 is on the order of one thousand hundreds V. The counter electromotive force is bypassed by the varistor 323 d. The varistor 323d generates heat due to the bypassed counter electromotive force, and the temperature gradually rises. In FIG. 12, Tp[℃]An example of the temperature change of the varistor 323d when the lighting system 77 is operated is shown.
As shown in fig. 7A to C, in the power supply device 320 according to the present embodiment, the 2 nd fuse 323b is disposed so as to be in contact with the outer surface of the varistor 323 d. The 2 nd fuse 323b is fixed to the varistor 323d by an adhesive member 323 e. In this way, the 2 nd fuse 323b is configured to be able to directly detect the temperature of the varistor 323 d.
The 2 nd fuse 323b detects the temperature of the varistor 323 d. Reaches a temperature T at the detected temperatureF[℃]When this occurs, the 2 nd fuse 323b blows. That is, the 2 nd fuse 323b has fusing characteristics to be fused according to the temperature of the varistor 323 d. T isF[℃]Is the temperature at which the 2 nd fuse 323b blows. The 2 nd fuse 323b blows to stop the supply of power to the power supply circuit 330. Thereby, the temperature of the varistor 323d decreases as shown in fig. 12.In this case, the temperature rise of the illumination device 70 is suppressed, and the illumination device 70 can be protected at a high temperature.
As described above, when the power supply device 320 according to the present embodiment is used, the illumination lamp 300 repeatedly blinks in the illumination system 77 that is not properly constructed. Thereby, the user can be notified that the glow starter 820 has not been replaced. The counter electromotive force generated at both ends of the lighting device 110 in a state where the illumination lamp 300 repeatedly flickers is bypassed by the varistor 323 d. Therefore, the lighting device 70 is protected at a high voltage. However, if the user does not find the blinking of the illumination lamp 300 and continues to repeat the blinking for a long time, the temperature of the illumination device 70 may increase. Here, in the present embodiment, if the temperature of the varistor 323d rises, the 2 nd fuse 323b melts. Therefore, the operation of the power supply device 320 is stopped, and the temperature rise of the lighting device 70 is suppressed. According to the above, the 1 st base 350, the illumination lamp 300, and the illumination device 70 can be prevented from being damaged or deteriorated in a high temperature state.
The time until the 2 nd fuse 323b is blown is short (t)f1) The lower case is, for example, about 30 seconds, and in the case of a long case (t)f3) The following is, for example, about 300 seconds. The time until the 2 nd fuse 323b melts is determined in consideration of the heat resistance of the circuit component 321 and the housing 352 provided in the 1 st base 350. The temperature T at which the 2 nd fuse 323b melts is determined in consideration of the heat resistance of the circuit member 321 included in the power supply device 320 and the heat resistance of the housing 352 included in the 1 st base 350F[℃]。
In the present embodiment, the 2 nd fuse 323b and the varistor 323d are bonded by the bonding member 323 e. On the other hand, the 2 nd fuse 323b may be disposed close to the varistor 323d so as to be able to detect the temperature of the varistor 323 d. The 2 nd fuse 323b may be provided in contact with the varistor 323d without using the adhesive member 323 e.
In the present embodiment, the 2 nd fuse 323b detects the temperature of the varistor 323 d. In contrast, the 2 nd fuse 323b may detect the temperature of a component other than the varistor 323d in the circuit component 321 that generates heat. In this case, the 2 nd fuse 323b is preferably disposed in contact with the circuit component 321 to be detected.
In the present embodiment, the 2 nd fuse 323b detects the temperature of the varistor 323 d. On the other hand, the 1 st fuse 323a may detect the temperature of the varistor 323 d. In addition, both the 1 st fuse 323a and the 2 nd fuse 323b may detect the temperature of the varistor 323 d.
In addition, even in the lighting device 10 in which the dummy starter 120 is accurately mounted, when an excessive current flows from the outside, the 1 st fuse 323a or the 2 nd fuse 323b can be blown to open the circuit. Therefore, even in the lighting device 10, the power supply device 320 or the light emitting unit 310 can be protected at a high temperature.
