Problems solved by technology
But with the adoption of this new design, a new problem arises, that is because the top of the pointer cap is the closest to the pointer light source and the area directly irradiated by the light source, when the light-emitting part of the pointer arm passes through the pointer cap, the pointer The brightness above the cap is always greater than the brightness of other parts of the pointer arm, resulting in uneven brightness of the light-emitting part of the pointer arm, which affects the overall effect and aesthetics of the pointer display after lighting

Embodiment Construction
[0018] Such as figure 1 As shown, a kind of automobile instrument lighting structure, comprises pointer cap 1, pointer arm 2, pointer shaft 6, light guide bracket 3, PCB board and the LED lamp 7 that is arranged on PCB board 4, and described pointer cap 1 is enclosed within Outside the pointer arm 2, the pointer arm 2 is connected to the light guide bracket 3 through the pointer shaft 6. The pointer arm 2 is provided with a main reflective surface 9, an auxiliary reflective surface 11 and a light guide column 10, and the incident light is routed by LED The lamp 7 points to the main reflective surface 9 and the auxiliary reflective surface 11 through the light guide column 10, and the reflected light is directed to the instrument pointer through the main reflective surface 9 and the auxiliary reflective surface 11.
[0019] The light guide column 10 is rectangular, so that the light emitted by the LED lamp 7 can be collected by the light guide column 10 and guided to the main r...

The invention relates to an automobile instrument illumination structure which comprises a pointer cap, a pointer arm, a pointer shaft and a light guide support frame, wherein the pointer cap is sleeved outside the pointer arm, the pointer arm is connected with the light guide support frame through the pointer shaft, the illumination structure is provided with an LED (Light Emitting Diode) lamp on a PCB (Printed Circuit Board), a main reflecting surface, an auxiliary reflecting surface and a light guide post are arranged on the pointer arm, an incident light path is pointed to the main reflecting surface and the auxiliary reflecting surface by the LED lamp through the light guide post, and the reflecting light path is pointed to an instrument pointer through the main reflecting surface and the auxiliary reflecting surface; three slot holes in triangular arrangement are arranged on the main reflecting surface, and incident rays are more intensively and uniformly irradiated on the instrument pointer through the main reflecting surface and the auxiliary reflecting surface, thus the brightness of the pointer arm is uniform, and the reliability and the decoration effect of the instrument are improved.
Description
technical field [0001] The invention relates to the field of automobile instruments, in particular to an illumination structure for an automobile instrument. Background technique [0002] With the development of society, the popularization of automobiles, and the application of new technologies, people have higher and higher requirements for the visual effect of automobile dashboards, and the most important thing for the visual effects of dashboards is the brightness and uniformity of the pointer on the dashboard. sex. As we all know, the brighter the pointer arm is, the longer the length of the illuminated part is, the clearer the reading will be and the better the visual effect will be. [0003] Due to the constraints of layout, shape, space and other factors, the luminous length of the pointer arm is always limited in one way or another, which is unsatisfactory. At this time, people think of extending the luminous length of the pointer arm to pass through the pointer cap...
