1, an LED module 20, a first SMPS 1, a second SMPS 2, a switch 3, and the like are electrically connected to each other, , And a dimming controller (6).

The LED module 20 includes a PCB 21 and a plurality of LEDs 22 mounted on the PCB 21. The LED module 20 includes a plurality of LED modules 20 connected in series or parallel- .

The LED module 20 may be lighted by a direct current power source, or may be lighted by an alternate current power source.

For example, if a fault occurs in a direct current LED module or a fault occurs in a direct current use SMPS when the direct current LED module is used while the LED module is turned on by a direct current and the LED module is turned on by an alternating current, It can also be used in place of the module.

The first SMPS 1 and the second SMPS 2 convert the inputted commercial power into a lighting power suitable for lighting the LED 22 of the LED module 20 and output it. The illuminance and the color temperature of the light emitted by the LED can be adjusted according to the characteristics of the lighting power source output to the first SMPS 1 or the second SMPS 2.

The switcher 3 selects and supplies commercial power to the first SMPS 1 or the second SMPS 2.

The switcher 3 includes a switch 4 for supplying commercial power to the first SMPS 1 or the second SMPS 3 by a switching operation and a CPU 5 for controlling switching of the switch 4, .

The CPU 5 checks the output of the first SMPS 1 or the second SMPS 2 and switches the switch 4 to determine whether there is a problem with the other (first or second) SMPS 1 , 2) to be supplied with commercial power. In other words, when the commercial power is supplied to the first SMPS 1, the output power of the first SMPS 1 is checked, and when the output power is out of the rated range, the switch 4 is switched to the second SMPS 2, To be supplied with commercial power.

In the SMPSs 1 and 2, the output power is unstable at the beginning of operation, and there may be an error in the check or judgment of the CPU 5. Therefore, it is preferable to check the output power after a predetermined time (for example, 3 seconds) elapses at the beginning of operation. If the SMPS (1, 2) has a problem, the other SMPS is activated.

As the switch 4, a semiconductor switching element such as a transistor or triac may be used, but it may be preferable to use a relay having a high operational stability. It may be desirable to use a latch relay that maintains the final switching state among the relays so that when the commercial power is newly supplied to the tunnels or the like, the previously operated SMPS is operated again.

The dimming controller 6 controls the dimming control signal, that is, a signal for adjusting the illuminance (which may further include the color temperature) of the illuminating light of the LED module 20 to the first SMPS 1 and the second SMPS 1, (2).

The dimming control signal of the dimming controller 6 may be a signal set in advance according to the position of a command signal, a tunnel or the like inputted according to a user's operation, an elapsed time or the like, a signal such as an illuminance sensor, Can be. The dimming controller 6 may transmit a dimming control signal to the first SMPS 1 and the second SMPS 2 in a power line communication (PLC communication) manner.

The housing 10 is fixed to a mounting surface in a tunnel and a bracket 11 is provided on a rear surface of the housing 10 to be fixed to a mounting surface of the housing 10, Or the like on the mounting surface.

The housing 10 includes a first body 13 and a second body 15. The first body 13 is a portion to which the bracket 11 is fixed and is in close contact with an installation surface. The second body 15 is hinged to the first body 13, , A switching unit, a dimming controller, and the like.

The first body 13 has first and second inner and outer portions 131 and 133 which are independent from each other.

The first inserting portion 131 is a place where the heat sink 23 connected to the rear of the LED module 20 is located and includes a plurality of heat dissipating holes 131a for emitting heat generated in the heat sink 23 And a second interpolation unit 133 is provided with SMPSs 1 and 2 for controlling the LED module 20, a switching unit 3, a dimming control unit 6, and the like.

Therefore, the first and the second interpolation units 131 and 133 form a separate space from each other, so that foreign matter, that is, dust, water, etc., flowing through the radiating hole 131a flows into the second inserting part 133 ).

The first main body 13 having the first and the second interpolation sections 131 and 133 is covered by the second main body 15. The first main body 13 and the second main body The second body 15 is composed of a first lid 151 and a second lid 153. The first lid 151 and the second lid 153 are spaced apart from each other, 151 and the second lid part 153. As shown in FIG.

The LED module 20 includes a PCB 21, a plurality of LEDs 22 mounted on the front surface of the PCB 21, and a PCB 21 and LED 22, And a transparent cover that covers the front of the PCB 21 and protects the LED 22.

As described above, the main object of maintenance in LED tunnels and the like is SMPS (1, 2). The SMPS 1 and 2 are fixed to the second insert portion 133 of the first main body 13 by using bolts. However, a tool such as a screw driver for tightening or unscrewing the bolts is required, And the dismantling work is cumbersome and time consuming, and there is a fear that the bolt is lost in the work week.

It is necessary to easily and quickly couple the SMPS 1 and 2 to the bottom of the second insertion portion 133 of the first main body 13 without a separate fastening tool such as a bolt and a driver, 1 and 2) are provided at the bottom of the second interpolation part 133 of the first body 13. And a coupling means for detachably coupling the transfer unit and the dimming controller.

Referring to Figures 4 and 5,

The side faces of the casing 61 of the SMPS 1 and 2 are inserted into the bottom of the housing 10, more specifically, the bottom of the second insertion portion 133 of the first body 13, A contact plate 62,

A guide groove 63 formed on the inner surface of the contact plate 62 in the forward and backward direction and deepened in the backward direction,

A depth adjusting plate 66 disposed at the bottom of the guide groove 63 for adjusting the depth of the guide groove 63 so that the guide groove 63 can be deepened rearward,

And an engaging ball 64 which moves along the guide groove 63.

The contact plate 62 is formed in a rectangular parallelepiped shape of the casing 61 of the SMPS and is disposed in a rectangular shape in which the side surface of the casing 61 is inserted and contacted.

It is preferable that the height of the casing 61 is longer than the contact plate 62 so that the operator does not have difficulty in holding the casing 61 by hand and inserting or separating it into the contact plates 62. [

An inclined block 67 having an inclined surface corresponding to the inclined surface of the inclined portion 66a is formed on the inner surface of the front side of the depth adjusting plate 66 by the guide groove 63, Backward grooves 63a formed on the bottom of the housing 62. [

The inclined block 67 is elastically supported in the forward and backward grooves 63a by a spring 68 so that it is normally advanced to push the inclined portion 66a. Thus, the front side of the depth adjusting plate 66 is supported at the bottom of the guide groove 63, and the guide groove 63 is deepened from the front to the rear.

A lever 67a is connected to the inclined block 67 downward and an end of the lever 67a is exposed through the contact plate 62. When the end of the exposed lever 67a is pushed backward, the inclined block 67 is moved backward in the forward and backward grooves 63a so that the front side of the depth control plate 66 can be lowered to the floor. When the end of the lever 67a pushed toward the rear side is released, the spring 68 pushes the inclined block 67 forward, and the front side of the depth adjusting plate 66 ascends in the guide groove 63 and comes back to the original position.

It is preferable that the engaging ball 64 and the casing 61 have a strong frictional force so that engagement by the engaging ball 64 is not arbitrarily released.

The process of detachably coupling and separating the casing 61 and the contact plate 62 of the SMPS through the coupling means 60 constructed as described above will be described with reference to FIG.

First, the casing 61 of the SMPS is pushed into the contact plates 62.

5A, the casing 61, which has entered the inside of the contact plates 62, moves backward from the front of the contact plate 62, and moves backward in the casing 61 5, the guide groove 63 is deepened while moving backward, so that the engaging ball 64 is guided by the guide groove 64 without any resistance, 63 to allow the casing 61 to move backward.

The end of the casing 61 further moves rearward beyond the engaging ball 64 and the engaging ball 64 is clogged behind the guide groove 63. [

Since the tunnels and the like usually have a structure for illuminating the top and bottom, the first main body 13 is disposed on the top. Therefore, the engaging ball 64 moves forward along the guide groove 63 due to its own weight, and stops at a position in contact with the side surface of the casing 61.

5, when the casing 61 is pulled in a state where both sides of the engagement ball 64 are in contact with the side surface of the casing 61 and the depth control plate 66, that is, The engaging ball 64 moves forward along the guide groove 63 due to frictional force and the depth of the guide groove 63 decreases toward the front and moves forward The engaging ball 64 presses the casing 61. As the engaging ball 64 moves forward of the guide groove 63, the urging force of the engaging ball 64 is stronger and the casing 61 is prevented from being detached and separated from the contact plate 62 by fixing the casing 61.

In this way, the casing 61 can be easily coupled to the inside of the contact plates 62 without any resistance, and even when the casing 61 is slightly separated forward from the inside of the contact plates 62 The engaging ball 64 strongly urges the casing 61 so that the engaging ball 64 is no longer detached and separated.

When separating the casing 61 of the SMPS from the inside of the contact plates 62, the lever 67a exposed to the outer surface of the contact plate 62 is pushed forward and the casing 61 is pulled out.

Referring to FIG. 5 [D], when the lever 67a is pushed forward, the front side of the depth adjusting plate 66 is lowered to deepen the front side depth of the guide groove 63, Enters the guide groove 63 and does not press the casing 61, the casing 61 is separated and separated from the inside of the contact plates 62 without any resistance.

While the present invention has been described in connection with the preferred embodiments thereof with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments and various modifications may be made without departing from the scope of the present invention. And should be construed as falling within the scope of protection of the present invention.
