Abstract

(57) [Summary] [PROBLEMS] The present invention fixes a neon tube and a step-up transformer for lighting a neon tube inside a side lamp for a vehicle and causes the lamp to emit light, so that a colored lens becomes unnecessary and the economical burden is reduced. Further, by bending the neon tube, the light emitting area is increased, and the visibility is improved. The power consumption is reduced by amplifying the weak power with a step-up transformer, and the waterproof process prevents water from entering and prevents accidents such as short circuits. SOLUTION: In the present invention, a heat radiating plate 2 is provided inside a vehicle side lamp, and a neon tube 1 and a step-up transformer 5 are fixed thereon and connected. The neon tube 1 was subjected to bending to increase the light emitting area and improve the visibility. The step-up transformer 5 and the neon tube connection part are waterproofed by a heat-shrinkable tube 6, and the power supply wiring cord 9 that goes out of the step-up transformer to the outside is a waterproof packing 1.
Go outside through 0. Further, the substrate 11, the heat radiating plate 2 and the lens 13 are fixed by pressing with a waterproof rubber ring 14 to prevent water from entering from outside. Since the neon tube 1 itself emits light, the lens 13 may be a kind of colorless and transparent.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a vehicle sidelight having a water-proof structure in which a neon tube and a voltage boosting transformer for lighting the neon tube are installed.

[0002]

[Prior art]

 The side lights for automobiles are mainly installed on the lower side of the loading platform of large trucks, etc., and are lit at night to allow other vehicles to see the overall length of the vehicle. The formula type is widely known. There are also a small number of LED lighting types.

[0003]

[Problems to be solved by the invention]

 Since the incandescent light has no color, the incandescent light itself has no color, so it is necessary to prepare multicolored lenses, which imposes a large economic burden. In addition, since a plurality of side lights are often attached to one vehicle, the burden on the vehicle increases due to an increase in power consumption. In addition, the LED lighting type side light has a narrow light irradiation angle due to the characteristics of the LED solid, and in order to enhance the visibility, it is necessary to incorporate a plurality of LED solids, which also has a large economic burden. Therefore, by using a neon tube, first, the color can be changed depending on the type of gas sealed in the neon tube, the voltage of the step-up transformer, etc., and since the neon tube itself develops color, there is only one kind of colorless and transparent lens. . The neon tube is a cylindrical glass tube that has been heated and bent to cover the inside of the sidelight, greatly improving visibility. Further, since the weak power is amplified by the step-up transformer and turned on, it is possible to reduce the power consumption and to solve the above-mentioned disadvantage.

[0004]

[Means for Solving the Problems]

 The present invention uses a neon tube as the illuminator of the side lamp for automobiles, develops several colors, and uses only one type of lens.The neon tube is bent to increase the light emission area. , Improving visibility. In addition, the power consumption is reduced because the micropower is amplified by the step-up transformer. In addition, the connection between the step-up transformer and the neon tube, the step-up transformer main body, and the board and lens connection are waterproofed to prevent water from entering from outside and prevent leakage. The heat generated by the step-up transformer is transmitted to the heat sink, and is released to the outside air from the substrate that is in close contact with the heat sink, thereby solving the problem.

[0005]

[Embodiment of the invention]

 Cut out a part of the heat sink at the center of the disk-shaped heat sink, secure the voltage boosting transformer with the raised nail, and cut out the electrode part of the neon tube to the left and right and cut out a part of the heat sink. Secure with raised nails. The boost transformer and the neon tube are connected by a wiring cord, and the connection is waterproofed using a heat-shrinkable tube. The neon tube is arranged so as to straddle the step-up transformer, and is spirally bent at the top. The heat sink that fixes the step-up transformer and the neon tube is in close contact with the substrate of the same shape, covered with a conical lens, and crimped with a waterproof rubber ring. The grounding wiring cord is connected to the heatsink and used as the body ground. The wiring cord that becomes the power supply goes out through the waterproof packing from the center of the bottom of the step-up transformer.

【Example】

 Hereinafter, an embodiment will be described with reference to the accompanying drawings. Reference numeral 1 denotes a neon tube formed by heating and bending a heat-resistant cylindrical glass, and a part of the radiator plate 2 is cut out, and is adhered and fixed to a nail for fixing the Neon tube 3 raised upward. The neon tube 1 is connected to a neon tube lighting voltage step-up transformer 5 by a wiring cord 4, and the connection portion is covered by a waterproof heat-shrinkable tube 6. The step-up transformer 5 is housed inside a case formed of a suitable material such as plastic and is sealed and waterproofed by a suitable material such as silicon. The step-up transformer 5 is formed by cutting out a part of the heat-dissipating plate 2 and adhesively fixed to a claw 7 for fixing the voltage step-up transformer, which is raised above, and serves as a grounding wire. The cord 9 exits through the waterproof packing 10 from the bottom center of the step-up transformer 5.

The rear part 2 of the heat sink is made of a metal having high thermal conductivity such as aluminum, and is closely attached to the substrate 11. The substrate 11 is made of a metal having high corrosion resistance, such as stainless steel, because it is a part that comes into contact with the outside air. The heat generated by the step-up transformer 5 is transmitted from the radiator plate 2 to the substrate 11 and released to the outside air. Further, since both the heat radiating plate 2 and the substrate 11 are made of metal, the wiring cord 8 serving as the ground connected to the heat radiating plate 2 is body-grounded to the metal part of the vehicle through a metal set screw 12 attached to the substrate 11. .

The substrate 11 and the heat radiating plate 2 are covered with a lens 13, and fixed by pressure bonding with a waterproof rubber ring 14.

[Effect of the invention]

 As described above, since the neon tube itself develops color, the lens is only one kind of colorless and transparent, and the economic burden of stocking multicolored lenses can be expected to be reduced. In addition, the neon tube is bent to improve the visibility by increasing the light emitting area, which leads to the improvement of safety. In addition, the load on the vehicle can be reduced because the weak power is amplified by the step-up transformer and turned on. In addition, the step-up transformer body, neon tube connection, power cable outlet, and the contact point between the lens and heat sink and substrate are waterproof to prevent water from entering from outside and prevent accidents due to short circuit.
