Embodiment Construction

[0026] The present invention will be further described below with reference to the prior art solutions and in conjunction with the accompanying drawings.

[0027] see figure 1 and figure 2 , an existing automobile gear letter indicator light has a single function color and only one light color, which includes a fixed plate 3, a printed circuit board 2 connected to the fixed plate 3, and a printed circuit board 2 installed on the fixed plate 3. The LED 21 is connected to the light box 1 on the fixed plate. Its working principle is to light up all the light-emitting diodes (LED lights) by supplying power to the whole vehicle, and then all the gear letters can be illuminated. The main disadvantage is that the layout takes up a lot of space, and its thickness δ1 must be greater than 15mm.

[0028] see image 3 , Figure 4 , Figure 5 and Figure 6 , a multi-color gear indicator light structure shown, including a cover plate 4, a PCB board 6, a plurality of LED lights 61 ar...

Abstract

The invention relates to a multi-color gear indicator lamp structure. The multi-color gear indicator lamp structure comprises a cover plate, a PCB and a plurality of LED lamps arranged on the PCB, andis characterized in that a plurality of light guide plates are arranged on the PCB, and the plurality of light guide plates are in one-to-one correspondence with gears; grooves are formed in the sidefaces of the light guide plates, the plurality of LED lamps are located at the positions of the grooves correspondingly, and the thickness of the light guide plates is 0.1 mm larger than the height of the LED lamps; reflecting paper is attached to the upper surface and the lower surface of each light guide plate, the upper surface of the cover plate is provided with and displays gear characters,the lower surface of the cover plate is provided with a plurality of light isolation plates, and the plurality of light isolation plates are used for separating the gear characters from one another, so that light is prevented from being mixed; and a plurality of clamping legs are arranged on the edge of the cover plate, the cover plate covers the PCB, and the plurality of clamping legs are fastened to the edge of the PCB. According to the structure, the gear characters can be uniformly illuminated, the structure is compact and small in occupied space, and the gear indicator lamps of 1-8 colorscan be arranged according to the requirement of the displayed gears.

Description

technical field [0001] The invention relates to a signal device for an automobile, in particular to a structure of a multi-color gear indicator light. Background technique [0002] At present, the function and color of the car gear letter indicator light are relatively single. Generally speaking, it is a mode of being off during the day and turning on at night, and there is only one light color. The main structure is that several light-emitting diodes are arranged under the gear letter panel. The working principle is as follows: All the gear letters can be illuminated by lighting up all the light-emitting diodes when the vehicle is powered (see figure 1 , figure 2 ). [0003] This structure can generally be applied in the case where the layout space is relatively rich (it takes up a lot of space and the thickness must be greater than 15mm). Since it is not limited by the space position, the distance between the light-emitting diode and the panel can be made far to realize...
