Description
Technical Field
The utility model relates to an automobile lamp technical field specifically is a thick wall light guide for on car light.
Background
The car light is an essential part on the car, and whether the appearance of the car light is beautiful directly influences the aesthetic property of the whole shape of the car. Therefore, each host factory has much time and effort on the appearance of the car lamp, and the car lamp is more beautiful as much as possible. Among them, the application of thick-walled light guides is a trend in recent vehicle lamps. However, the conventional thick-walled light guide member generally has a thickness of 10mm or less and a length of 500mm or less, and the thick-walled light guide member cannot satisfy the customer's requirements for the design of the automobile lamp, and the conventional thick-walled light guide member is poor in optical uniformity because the LED particles are visible from the front of the light guide when the light guide is turned on.
Disclosure of Invention
The utility model aims to improve the optics homogeneity of thick wall light guide, increase thick wall light guide component's size for satisfy figurative variability and the aesthetic property of car light.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a novel thick-walled light guide, characterized in that it is composed of not less than 7 optical building blocks, each optical building block comprising: the device comprises a reflecting bowl 1, a condenser 2, an optical pattern surface 3, a light blocking rib 4, a main body mounting structure 5, a screw column a6, a screw column b7 and a screw column base surface 8;
in the optical structure unit, a condenser 2, a light blocking rib 4, a screw column a6, a screw column b7 and a screw column base surface 8 are arranged on the upper surface of the thick-wall light guide, a main body mounting structure 5 is arranged on the lower surface of the thick-wall light guide, a reflecting bowl 1 is arranged on the rear surface of the thick-wall light guide, and an optical pattern surface 3 is arranged on the front surface of the thick-wall light guide; light rays emitted by the light source can be converged and reflected on the reflecting bowl 1 through the condenser 2, and then are reflected by the reflecting bowl 1 to generate horizontal light rays which enter the optical pattern surface 3;
the rear of the condenser 2 is a screw column base surface 8, the screw column base surface 8 is provided with a screw column a6, the front of the condenser 2 is provided with a screw column b7, and the front of the screw column b7 is provided with a light blocking rib 4.
The thick-wall light guide is made of an optical-grade transparent PC material in an injection molding mode, the length of a main body is 1000mm, the thickness of the main body is 20mm, and the width of the main body is 50 mm.
Through the above design scheme, the utility model discloses following beneficial effect can be brought: the utility model provides a novel thick wall light guide size has accomplished length 1000mm, and thickness 20mm has satisfied the changeable demand that can be more on the car light molding, structurally designed spotlight ware and reflection bowl structure simultaneously to at the positive front of thick wall light guide designed optics flower pattern face, from the light that LED sent through spotlight ware, reflection bowl, optics face, the light that becomes evenly distributed is spilled once and again. Therefore, the LED particles are not visible when the LED lamp is lighted, and the optical uniformity is greatly improved. Through the utility model discloses the application of thick wall light guide can make the signal lamp of car look crystal-clear, and optics homogeneity is better, and the outward appearance looks more beautiful, can be more changeable in the molding.

Detailed Description
As shown in fig. 1, 2, 3 and 4, the light guide of the present invention is made of optical grade transparent PC material by injection molding. The thick-walled light guide body has a length of 1000mm, a thickness of 20mm and a width of 50 mm.
The back of the thick-wall light guide main body is provided with a reflecting bowl 1; the condenser 2, the screw column a6, the light blocking rib 4, the screw column b7 and the screw column base surface 8 are arranged on the light blocking device; the front surface is provided with an optical pattern surface 3; the lower surface is provided with a main body mounting structure 5
As shown in fig. 5, after the light is emitted from the light source, the light is refracted onto the reflection bowl 1 through the condenser 2, then reflected by the reflection bowl, the light is transmitted in the vertical direction and is transmitted in the horizontal direction, and then reflected by the optical pattern surface 3, the light is transmitted in the horizontal direction and is diffused. Thereby meeting the regulatory and aesthetic requirements of the signal lamp.
The thick-wall light guide is connected with the circuit board assembly through the screw post a6, is connected with the thick-wall light guide support through the screw post b7, and is connected with the thick-wall light guide support through the main body mounting structure 5.
This concludes the description of the embodiments of the present invention.
