Waterproof device for LED lamp of motorcycle

Abstract

The invention provides a water-proof device of motorcycle LED lamp, which comprises the following parts: base, circuit base board, decorative board and lamp shade, wherein the rear of decorative board contains extension part, which forms sealing water-proof structure with inner wall of base to cover the circuit base board. The invention prevents the circuit base board from water, which improves the decorative property under the water.

Description

【Technical field】 [0001] The invention relates to a waterproof device of a lamp, in particular to a waterproof device of an LED (light emitting diode) lamp for a motorcycle. 【Background technique】 [0002] Such as figure 1 As shown, in order to comply with the specifications of safety and traffic regulations, a headlight 11, a front direction light 12, a rear light 13, a rear direction light 14 and a license plate light 15 must be installed on the motorcycle 1 at least. As a light source, there are no more than two categories: light bulbs and LEDs (light emitting diodes). As far as LED lamps are concerned, please refer to figure 2 As shown, the LED lamp 2 is mainly composed of a base 21 , a circuit board 22 , a decorative plate 23 and a lampshade 24 . [0003] Such as figure 2 As shown, the base 21 is provided with at least two fixing columns 211 , and the fixing columns 211 are provided with screw holes 211 a, and the fixing columns 211 can be used for locking the fixi...

AI Technical Summary

Problems solved by technology

However, the LED lamp 2 will need to be repaired due to damage, so when the LED lamp 2 is damaged, the fixing screw S must be removed, and the lampshade 24, the decorative plate 23 and the circuit board 22 must be removed for maintenance. After several times of maintenance, the outer peripheral edge 242 of the lampshade 24 will often fail to tightly bond with the washer P in the socket 212 of the base 21, and the washer P itself is made of rubber material, which will also be aging and deformed. , so that the original waterproof function of the LED lamp 2 is lost, and the external water will penetrate into the interior of the lamp 2 along the joint between the base 21 and the lampshade 24, such as Figure 4 As shown, some seepage water will directly drip on the circuit substrate 22, making the circuit substrate 22 into a wet state. When the user of the motorcycle 1 starts the power supply of the LED lamp 2, the circuit substrate 22 of the LED lamp 2 will Leakage occurs due to moisture, which in turn causes a short circuit, causing the circuit board 22 or the LED lamp 3 to burn out, making the LED lamp 2 unusable. This drawback has existed in the conventional motorcycle LED lamp 2 for a long time. Motorcycle manufacturing The industry also has no countermeasures such as improvement, so the improvement of the waterproof function of LED lamps 2 is a big problem that motorcycle manufacturers currently need to solve.
