Description

Anti-dazzle LED fog lamp

Technical Field

The utility model relates to a car light structure field especially relates to an anti-dazzle LED fog lamp.

Background

Fog lamps are generally referred to as automotive fog lamps. The automobile fog lamps are arranged at the front part and the rear part of the automobile and used for illuminating roads and giving safety warnings when the automobile runs in rainy and foggy days, and visibility of drivers and surrounding traffic participants is improved.

In the fog lamp in the prior art, the top view and the cross section of the lamp shade are shown in the first drawing, the grid-shaped vertical stripes are only arranged on the surface of the lamp shade, the reflection times of light are low, and the reflection path of the light is short, so that the fog-proof effect of the fog lamp is poor.

When a vehicle runs in a foggy day, the fog lamp can cause instantaneous blinding to a driver in vision, glare occurs, visual conditions of visual discomfort and reduction of object visibility are caused due to inappropriate brightness distribution in a visual field, and the observation capability and the warning capability of surrounding pedestrians and vehicles coming from front and back are greatly reduced, so that the fog lamp for the vehicle with high glare elimination performance is needed to solve the technical problems.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an anti-dazzle LED fog lamp solves the dizzy poor problem of effect of current automobile-used fog lamp anti-dazzle.

In order to solve the technical problem, the utility model adopts the technical scheme that: the anti-dazzle LED fog lamp is characterized in that: comprises that

The LED lamp comprises a lamp holder, wherein a plurality of uniformly distributed LED lamp beads are mounted on the lamp holder;

the lampshade is installed on the lamp holder and comprises a lampshade body, the lampshade body is of a circular cover body structure, a double-hole structure is arranged on the lampshade body and comprises small grooves evenly arranged on the inner wall of the lampshade body and large grooves evenly arranged on the inner wall of the lampshade body, and the small grooves correspond to the large grooves one to one.

Furthermore, the big grooves and the small grooves are arranged in a circular array.

Furthermore, the size of the large groove is R, the size of the small groove is R, and the ratio of R to R is 1.25 to 2.75.

Further, the distance between the two large grooves is a, and the ratio of a to R is 0.5 to 1.5.

Furthermore, the distance between the peaks of the small groove and the large groove is L, and the ratio of L to R is 1 to 2.5.

Further, the LED lamp beads are also distributed on the lamp holder in a circular array mode.

The utility model has the advantages that:

1) In the utility model, the double-hole structure is arranged on the lampshade body and comprises small grooves evenly arranged on the inner wall of the lampshade body and large grooves evenly arranged on the inner wall of the lampshade body, and the small grooves and the large grooves are in one-to-one correspondence, and the small grooves and the large grooves are matched, so that the refraction times can be increased, thereby increasing the reflection path of light and finally leading the utility model to have better glare elimination;

2) The utility model discloses in, when the ratio of R and R is 1.25 to 2.75, the ratio of a and R is 0.5 to 1.5 and the ratio of L and R is 1 to 2.5, LED's whole light energy utilization ratio can improve to 92%, horizontal direction and vertical direction illuminance uniformity improve respectively to 83.5% and 75.5%, the refraction number of times of LED lamp pearl is best to elimination dazzling light effect at this moment is optimal;

3) The utility model discloses in, install a plurality of evenly distributed's LED lamp pearl on the lamp stand, and LED lamp pearl is circular array and arranges on the lamp stand, adopts the multiple spot light source promptly, improves the homogeneity of light source when making this device's luminance higher, finally makes the warning performance of this device when the use of fog day better.

Detailed Description

An anti-glare LED fog lamp as shown in fig. 3 to 4 comprises a lamp holder 1, a lampshade 2 and LED lamp beads 3.

A plurality of evenly distributed LED lamp beads 3 are installed on the lamp holder 1, and the LED lamp beads 3 are arranged on the lamp holder 1 in a circular array.

The lampshade 2 is arranged on the lamp holder 1 and completely covers all the LED lamp beads 3, the lampshade 2 comprises a lampshade body 21, the lampshade body 21 is of a circular lampshade body structure, and a double-hole structure is arranged on the lampshade body 21.

The double-hole structure comprises small grooves 22 evenly arranged on the inner wall of the lampshade body 21 and large grooves 23 evenly arranged on the inner wall of the lampshade body 21, the small grooves 22 correspond to the large grooves 23 one to one, and the large grooves 23 and the small grooves 22 are all arranged in a circular array.

Wherein the size of the large groove 23 is R, the size of the small groove 22 is R, and the ratio of R to R is 1.25 to 2.75.
