Background
With the continuous development of automobile headlamp technology, the automobile headlamp plays more and more important roles in road illumination and identification of obstacles in front of driving, people have not satisfied the adoption of halogen bulbs and xenon lamps as light emitting sources, and LEDs are more and more applied to automobile illumination, so that the automobile headlamp has the advantages of long service life, high light emitting efficiency, low energy consumption, small heat generation, easy adjustment and impact resistance, and compared with the prior art, the halogen lamps have dim light rays and are easy to cause visual fatigue when driving at night; the xenon lamp has weak physical spectrum penetrating power, low bulb lighting speed and short service life, and the traditional halogen headlamp and xenon headlamp in the market are gradually replaced by the LED headlamp.
At present, corner lamps or all-weather lamps in the market are mostly in a reflector form, under the condition of the same model, the illumination range meets the standard requirement, but the illumination width is relatively narrow, the detection capability for pedestrians on two sides of a road is not high, hidden dangers exist, and safety problems can be caused in the driving process.
SUMMERY OF THE UTILITY MODEL
For solving the not enough of above-mentioned prior art, the utility model provides a thick wall formula light guide structure that can be used to LED corner lamp adopts following technical scheme: a thick-walled light guide structure useful in LED corner lamps, comprising: the light source comprises a light source 1, a light guide light incoming surface 2, a side wall 3, a light guide light outgoing surface 4, a mounting structure 5 and a main body structure 6; the light guide light incoming surface 2 is located at the bottom of the main body structure 6, the side wall 3 is located above the main body structure 6, the light guide light outgoing surface 4 is located at the top of the side wall 3, the mounting structures 5 are located at edges of two sides of the main body structure 6, and the light source 1 is located below the main body structure 6.
The light guide light incident surface 2 is a plane.
The light guide light-emitting surface 4 is a free-form surface. The light source 1 is an LED particle and is positioned on a free-form surface focus of the light guide light-emitting surface 4. Vertical stripes are arranged on the free curved surface of the light guide light-emitting surface 4.
The thick-wall type light guide structure is prepared by adopting a one-time injection molding method.
The mounting structures 5 are of limiting column structures, and the number of the mounting structures is 2.
Through technical scheme, can realize that car corner lamp improves left and right sides lighting width under the condition that does not increase the size, compare with equal figurative traditional structure corner lamp, can reduce the light source number and reduce the radiator size, and have more energy-efficient, the better illuminating effect of homogeneity.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1, 2 and 3, a thick-walled light guide structure for an LED corner lamp includes: the light source comprises a light source 1, a light guide light incoming surface 2, a side wall 3, a light guide light outgoing surface 4, a mounting structure 5 and a main body structure 6; the light guide light incidence surface 2 is located at the bottom of the main body structure 6, the side wall 3 is located above the main body structure 6, the light guide light emergence surface 4 is located at the top of the side wall 3, the mounting structure 5 is of a 2-limiting-column structure and located at the edges of two sides of the main body structure 6, and the light source 1 is located below the main body structure 6.
The thick-wall type light guide structure is prepared by adopting a one-time injection molding method.
The light guide light incoming surface 2 is a plane, and the light guide light outgoing surface 4 is a free-form surface. The light source 1 is placed at a position 1mm away from the light guide light incoming surface 2, the light source 1 is LED particles, light emitted by the LED particles enters the thick-wall light guide body structure 6 through the light guide light incoming surface 2, part of the light directly reaches the light guide light outgoing surface 4, part of the light reaches the side wall 3, so that total reflection occurs, the angle of the side wall 3 is adjusted by utilizing the optical total reflection principle, the light reaches the light guide light outgoing surface 4 after multiple total reflection, the horizontal direction and the vertical direction of the light guide light outgoing surface 4 are asymmetric, the light can be converged in a range of 1-10 degrees below the horizontal line in the vertical direction according to the optical refraction principle, light distribution in the vertical direction is completed, and the horizontal direction mainly adjusts the angle of the side wall 3 by utilizing the optical total reflection principle.
The basic surface of the light guide light-emitting surface 4 is a free curved surface, the visual effect is similar to the outer surface of a bracelet, the light guide light-emitting surface converges in the vertical direction to enable the emergent light to be concentrated in the height range of 10 degrees, the diffused emergent light in the left and right directions is distributed in the width range of 50 degrees in the horizontal direction, the range can be adjusted, and the light guide light-emitting surface 4 is added with longitudinal strip-shaped optical patterns to further improve the effects of light distribution broadening in the horizontal direction and uniformity. The specific light extraction effect is shown in fig. 4 and 5.
This concludes the description of the embodiments of the present invention.
