(Configuration of power supply circuit 62)
The power supply circuit 62 includes an AC power supply 61, a rectifier diode 77, and smoothing capacitors 78A and 78B. As the AC power supply 61, a commercial AC power supply of AC100V or 200V is used. For example, in the case of AC 200V, the rectifier diode 77 forms a bridge diode with four diodes, and rectifies the waveform of the current from the AC power supply 61. The smoothing capacitors 78A and 78B smooth the waveform of the current rectified by the rectifier diode 77. For example, the power supply circuit 62 converts AC 200V alternating current into approximately 280V direct current. In the case of AC100V, when the power supply circuit 62 is a double wave voltage doubler rectifier circuit, it is converted to a direct current of about 280V as in the case of AC200V.

(Configuration of control circuit 69)

The FET 67 is turned ON / OFF under the control of the controller 68. The controller 68 detects ON / OFF control of the FET 67 by detecting the current flowing through the current detection resistor element 66 as described above.

(Operation of the lighting device 1)
FIG. 7 shows the lighting device 1 assembled by combining the substrate 3 on which the LED 2 is mounted, the upper case 4, and the lower case 5 in an upper plane (a), a front plane (b), and a lower plane (c). FIG.

  Two upper cases 4A that are approximately half the length of the long substrate 3 are mounted side by side on the first surface 3a side, while the second case 3A is approximately half the substrate 3 on the second surface 3b side. The lower case 5A having a length of 1 and the lower case 5B having a length of ¼ are combined, and the lower case 5B, the lower case 5A, and the lower case 5B are arranged in this order. The upper case 4 and the lower case 5 may be connected to the power supply unit 60 in a state where they are connected in series by a connector or the like, and each of the upper case 4 and the lower case 5 is connected to the power supply unit 60. Also good.

(Lighting operation of lighting device 1)
In the lighting device 1, an AC 200V AC power supply 61 includes a resistance element 74A having a resistance value of 12 kΩ, resistance elements 74B and 74C having a resistance value of 1 kΩ, and a resistance element 74D having a resistance value of 100 kΩ. Further, it is assumed that the NPN transistor and the PNP transistor are turned on when the base voltage of the NPN transistor of the control element 73 is 0.65 V or more.

  First, for example, AC from a 200 VAC AC power supply 61 is full-wave rectified by a rectifier diode 77, smoothed by a smoothing capacitor 78, and converted to about 280 VDC. Next, when the FET 67 is turned on by the controller 68, the current flows through the LED 2 → the coil 71 → the FET 67 → the current detecting resistance element 66, and the LED 2 is turned on. When it is detected that a predetermined amount of current is flowing due to the voltage generated in the current detection resistor element 66, the FET 67 is turned off. In this case, the current stored as energy in the coil 71 when the FET 67 is turned on flows from the coil 71 to the fast recovery diode 70 → LED2, and the lighting state of the LED2 is maintained. However, since the current to the LED 2 gradually decreases, the FET 68 is turned on by the controller 68 after a certain time. For this reason, the current flows through the LED 2 → the coil 71 → the FET 67 → the current detecting resistance element 66, and the LED 2 is turned on. In this way, a substantially constant current flows through the LED 2.

  Here, when the LED 2 is operating normally, for example, when the VF value of the LED 2 is 3 V, the voltage divided by the resistance elements 74A and 74B is about 0.38 V, and the PNP transistor of the control element 73 is The OFF state remains between the emitter terminal and the emitter terminal of the NPN transistor.

  By the lighting operation of the LED 2 as described above, light is irradiated from the LED 2 mounted on the first surface 3 a side of the substrate 3 through the upper lens portion 4 a located above each LED 2. Thereby, each LED2 can illuminate the article for exhibition which is an illumination object effectively.

  The lighting device 1 can be provided with a dimming function by controlling the dimming circuit 79 for driving the LED 2 by reducing the output voltage of the power supply unit 60 by the controller 68.

(Operation of the lighting device 1 when the LED 2 has an open failure)
On the other hand, for example, when any one LED 2 has an open failure and a voltage of 8.45 V or more is applied to both ends of the LED 2, the voltage divided by the resistance elements 74A and 74B exceeds 0.65 V. The PNP transistor emitter terminal and the NPN transistor emitter terminal of the control element 73 are turned on. That is, both ends of the LED 2 that has failed to open are short-circuited by the control element 73. For this reason, the supply of current from the power supply circuit 62 to other LEDs (LED elements that can operate normally) 2 of the LED element 2 that has failed in the open state is continued.

  When the supply of current is interrupted from this state, the emitter terminal of the PNP transistor and the emitter terminal of the NPN transistor of the control element 73 are turned off. Between the emitter terminal of the PNP transistor and the emitter terminal of the NPN transistor is turned on, and both ends of the LED 2 that has failed to open are short-circuited.

  In the present embodiment, the case where a single LED element 2 has an open failure has been described. However, the present invention is not limited to this, and even when a plurality of LEDs 2 have an open failure, the same as in the present embodiment. The other LEDs 2 other than the plurality of LEDs 2 having the open failure can be normally operated.

  As a result of the lighting operation of the LED 2 as described above, the LED 2 that has an open failure and shares the LED protection circuit with the LED 2 is not turned on, but the other LEDs 2 mounted on the first surface 3a side of the substrate 3 Light is irradiated through the upper lens portion 4a located above the LED 2. Thereby, even if it is the structure which connects LED2 in series, the influence by the open failure of LED can be suppressed to the minimum.

(Effects of the first embodiment)
(1) In the first embodiment, as shown in FIG. 1 or FIG. 7, two upper cases 4 </ b> A that are approximately half the length of the long substrate 3 are provided on the first surface 3 a side. On the other hand, on the second surface 3b side, a lower case 5A that is approximately half the length of the substrate 3 is attached to the central portion, and a lower case 5B that is ¼ length on both sides thereof. Each is attached. When the upper case 4 and the lower case 5 are attached to the long substrate 3 in such an arrangement, the boundary region 90 between the upper case and the boundary region 91 between the lower cases shown in FIG. In FIG. 5, the positions are not matched and are in different positional relations. Therefore, even if a bending force is applied to the lighting device 1, the force is received by at least two members of the substrate 3, the upper case 4 and the lower case 5, so that the rigidity of the lighting device 1 is sufficiently secured and sufficiently strong. A lighting device 1 can be obtained.

  (2) Since the lighting device 1 is configured by combining the upper case 4 and the lower case 5 shorter than the substrate 3 with respect to the long substrate 3, the molding dies for the upper case 4 and the lower case 5 are provided. The manufacturing cost can be greatly reduced. In addition, the upper case 4 and the lower case 5 are a plurality of types of covers formed with different lengths, but each has a different arrangement order when mounted, and the first surface 3a and the second surface are different. Since 3b can use the same cover, it has the effect of reducing member costs, material costs, and the like.

  (3) In the upper case 4, since the upper lens portion 4a is formed integrally with the main body of the upper case, the light emitted from the LED 2 can be efficiently radiated to the outside. Since it is not necessary, the number of parts can be reduced, the number of assembly steps can be reduced, and the cost can be reduced.

  (4) Since the lower lens portion 5a is also formed integrally with the lower case body in the lower case 5, the light emitted from the LED 2 can be efficiently emitted to the outside, and other members such as a reflector can be used. Since it is not necessary, the number of parts can be reduced, the number of assembly steps can be reduced, and the cost can be reduced.

  (5) By providing the LED protection circuit 80, it is possible to minimize the influence at the time of an open failure of the LED 2, so that the LED 2 can be connected in series to drive and emit light, which is effective for energy saving. It is possible to drive the LED, that is, to use the lighting device 1 effective for energy saving.
