It is a disassembled perspective view of the vehicle lamp which shows another embodiment of this invention. It is principal part sectional drawing which shows the waterproof structure of the vehicle height light of FIG. It is a principal part enlarged view which shows the light distribution system of the vehicle height light of FIG.

  Hereinafter, some embodiments in which the present invention is embodied in a vehicle height light will be described with reference to the drawings. A vehicle light 1 shown in FIG. 1 is installed at a height at the back of a container vehicle. The lamp body 3 of the vehicle lamp 1 is attached to the vehicle body 2 by two screws 5 together with the translucent cover 4 in a state of protruding to the outside of the vehicle body (container) 2.

  As shown in FIGS. 2 and 3, a light source base 6 is disposed between the lamp body 3 and the translucent cover 4, and a first packing 7 is interposed between the light source base 6 and the lamp body 3, A second packing 8 is interposed between the lamp body 3 and the vehicle body 2. On the surface side of the light source base 6, a light source substrate 10 is supported by a pair of support pieces 9, and is covered from the outside of the vehicle body by a translucent cover 4.

  The entire circumference of the translucent cover 4 is welded to the light source base 6 (welded portion 11), and the lamp chamber 12 is hermetically sealed between the light source base 6 and the translucent cover 4. In order to ventilate the lamp chamber 12, a small hole 13 is formed in the light source base 6, and a breathable filter 14 that covers the small hole 13 is attached to the back surface of the light source base 6.

  As shown in FIGS. 3 and 4, a plurality of LEDs 15 as semiconductor light emitting elements are arranged on the surface of the light source substrate 10. A wiring holder 16 is interposed between the light source substrate 10 and the light source base 6, a plurality of connection conductors 17 are held in the wiring holder 16, and a base end of each connection conductor 17 is a contact 18 ( (See FIG. 4).

  On the support piece 9 of the light source base 6, a latching claw 9 a that latches both ends of the light source substrate 10 from the LED 15 side is formed. The wiring holder 12 is sandwiched between the light source substrate 10 and the light source base 6 by the latching claws 9 a, and the contact 18 is pressed against the base end of the connection conductor 17 by the elasticity of the light source substrate 10.

  A cylindrical power receiving connector 19 is integrally formed on the rear surface of the central portion of the light source base 6 so as to protrude toward the vehicle body 2, and the tip of the connection conductor 17 passes through the light source base 6 and is inserted into the power receiving connector 19. ing. A wiring chamber 20 that houses the power receiving connector 19 is formed inside the lamp body 3, and the power feeding connector 21 on the vehicle body 2 side can be connected to the power receiving connector 19 in the wiring chamber 20.

  Therefore, according to the vehicle lamp 1 of this embodiment, since the power receiving connector 19 is provided on the light source base 6, the power supply lead on the lamp side can be eliminated, and troubles such as wiring and storage can be saved. Further, since the power receiving connector 19 is accommodated in the wiring chamber 20 of the lamp body 3, the connection work with the power supply connector 21 can be easily performed outside the vehicle body 2.

  In the vehicle lamp 1 shown in FIG. 5, a pair of attachment portions 22, 23 are provided on the back surface of the light source base 6 so as to be positioned on the left and right sides of the power receiving connector 19. An elastic piece 22a that engages with the other attachment portion 23 is formed, and a locking projection 23a that is locked to the inner peripheral edge on the opposite side is formed. According to this mounting structure, there is an advantage that the translucent cover 4 and the light source base 6 are integrated by welding (welding portion 11) and can be attached to and detached from the lamp body 3 with one touch.

  The vehicle lamp 1 shown in FIGS. 6, 7, and 8 includes an annular waterproof wall 24 that surrounds the power receiving connector 19, and bright ribs 25 are formed at both ends of the translucent cover 4. The waterproof wall 24 is formed on the back surface of the light source base 6 so as to protrude inside the lamp body 3, and the protruding end surface of the waterproof wall 24 is pressed against the packing 8 in the wiring chamber 20. According to this structure, there exists an advantage which can protect the connection part of the connectors 19 and 21 reliably from rain water with the packing 8 of 1 sheet.

  As shown in FIG. 8A, a plurality of the bright ribs 25 are formed at the end of the translucent cover 4 through the grooves 26. A total reflection step 27 is formed on the surface of the translucent cover 4 above the LED 15 so as to be located directly beside each groove 26. For example, three total reflection steps 27 are disposed in the vicinity of the LED 15 located at the end of the light source substrate 10, and two total reflection steps 27 are disposed in the vicinity of the inner LED 15. 27 can be arranged in a staggered fashion.

  As shown in FIG. 8B, a plurality of internal and external total reflection surfaces 28 are formed on the end wall portion 4 a of the translucent cover 4 at positions corresponding to the grooves 26. Then, the light from the LED 15 is reflected by the total reflection step 27, travels straight inside the translucent cover 4 toward both ends, is refracted by the total reflection surface 28 of the end wall portion 4 a, and part of the refracted light is the bright rib 25. Another refracted light is diffused from the groove 26 to the outside through the inside. Therefore, according to this configuration, the light emission of the LED 15 can be effectively used, and the bright ribs 25 at both ends of the translucent cover 4 can be beautifully emitted to enhance the design of the vehicle lamp 1.

  The present invention is not limited to vehicle height lights, and can also be applied to various vehicle lamps such as high-mount signal lamps for passenger cars and beacon lights for trucks. In addition, the shape and configuration of each part can be changed as appropriate without departing from the spirit of the invention.
