Abstract

The utility model relates to a U-shaped disk interface indicating lamp of a vehicle-mounted compact disc (CD) player. The U-shaped disk interface indicating lamp of the vehicle-mounted compact disc (CD) player comprises a light guide body with a U-shaped groove at one end, the inner wall of the U-shaped groove is a U-shaped out-light surface, an in-light surface is arranged at the other end of the light guide body, a light source is arranged at the position of the in-light surface, a reflective film is coated on other surfaces of the light guide body except the in-light surface and the U-shaped out-light surface, a positioning hole is arranged on the light guide body, and the light guide body is further provided with a light dimming hole. The light dimming hole is arranged on the light guide body, light which radiates to the middle originally is diffused to two sides through refraction and reflection of light at the position of an interface of the light guide body at the light dimming hole and the air, light distribution of the U-shaped out-light surface is even, and luminance is high. Through adjustment of shape, size and position of the light dimming hole, evenness of out-light surface light can be adjusted, and cost cannot be increased remarkably.

Description

The U-shaped dish mouth of a kind of vehicle-mounted CD player indicator lamp

Technical field

The utility model relates to a kind of vehicle-mounted CD player dish mouth indicator lamp.

Background technology

Along with the continuous increase of vehicle electronics matching product, people are also more and more higher for the quality requirement of vehicle electronics product at present.Vehicle-mounted CD player dish mouth indicator lamp a variety of shapes are arranged, and U shape indicator lamp illuminates with a LED lamp, and the light of U-shaped exiting surface is all inhomogeneous, and some places are darker, and some places are too bright again.Affect like this aesthetics and deixis.

The utility model content

In view of this, technical problem to be solved in the utility model provides the U-shaped dish mouth of a kind of vehicle-mounted CD player indicator lamp.

The technical scheme that this practical information solves the problems of the technologies described above is:

The U-shaped indicator lamp of a kind of vehicle-mounted CD player dish mouth, comprise that an end is with the light conductor of U-shaped groove, U-shaped groove inwall is the U-shaped exiting surface, the light conductor other end is provided with into the light face, advance Guang Mianchu and be provided with light source, other each face of light conductor except advancing light face and U-shaped exiting surface scribbles reflectance coating, has locating hole on the described light conductor, also has the light modulation hole on the described light conductor.

Further, open at the U-shaped trench bottom of light conductor and vertical with plane, U-shaped groove place in described light modulation hole.

Further, on the axis that is centered close to light conductor in described light modulation hole.

Further, described light modulation hole is shaped as quadrangular.

The beneficial effects of the utility model are:

The utility model is offered the light modulation hole at light conductor, refraction and the reflex of the light at the interface place by light modulation hole place light conductor and air, to originally want the divergence of beam at directive middle part to arrive both sides, so that the distribution of light of U-shaped exiting surface is more even, brightness be larger.And, by adjusting shape, size, the position in light modulation hole, can adjust the uniformity of exiting surface light, and can significantly not increase cost.

Description of drawings

Fig. 1 is the structural representation of the U-shaped dish mouth of the vehicle-mounted CD player of embodiment indicator lamp.

Fig. 2 is the symmetrical structural representations that consist of a complete vehicle-mounted CD player dish mouth indicator lamp of placing of two the U-shaped dish mouth of vehicle-mounted CD player indicator lamps.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

Embodiment

As shown in Figure 1, the U-shaped dish mouth of a kind of vehicle-mounted CD player indicator lamp, comprise that an end is with the light conductor 5 of the L-type of U-shaped groove 7, U-shaped groove 7 inwalls are U-shaped exiting surface 2, light conductor 5 other ends are provided with into light face 1, enter light face 1 place and are provided with light source 6, and other each face of the light conductor 5 except advancing light face 1 and U-shaped exiting surface 2 scribbles reflectance coating, have locating hole 4 on the described light conductor 5, also have light modulation hole 3 on the described light conductor 5.Described light modulation hole 3 is opened in U-shaped groove 7 bottoms of light conductor 5 and is vertical with plane, U-shaped groove 7 place, be shaped as quadrangular, and it is centered close on the axis of light conductor 5.

Owing to have light modulation hole 3 at light conductor 5, originally to reflect, disperse through the light modulated light hole 3 of 3 positions, light modulation hole, make the distribution of light of U-shaped exiting surface 2 more even, brightness is larger.

Except present embodiment, can also pass through to adjust shape, size, the position in light modulation hole, thereby adjust the uniformity of exiting surface light.

As shown in Figure 2, two symmetrical placements of the U-shaped dish mouth of vehicle-mounted CD player indicator lamp have just consisted of the indicator lamp of a complete vehicle-mounted CD player dish mouth.

The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art any apparent improvement and the replacement made are within the claim protection domain of the present utility model under the prerequisite that does not break away from the utility model principle.
