Embodiment Construction

[0027] Such as Figure 1~3 , a total reflection type thick-walled concentrator, including a combination type concentrator, the combination type concentrator includes a total reflection arc prism 2 arranged in front of the light source, a total reflection arc prism 2 outer edge The curved surface refraction concentrator 1 and the outer edge of the combination type concentrator are provided with a total reflection side wall concentrator 3, and the shape of the edge of the entire total reflection thick wall concentrator corresponds to the shape of the light emitting surface of the car lamp. Total reflection side wall concentrator 3 The principle of total reflection makes full use of light at a large angle. The combined concentrator and the total reflection side wall concentrator 3 form an optical system, which can be applied to various irregular light emitting surfaces.

[0028] Both the curved refraction concentrator 1 and the total reflection curved prism 2 are formed by stret...

Abstract

The invention relates to the technical field of automobile lamps, and in particular, relates to a total-reflection type thick-wall condenser and a lighting device. The total-reflection type thick-wallcondenser includes a combined condenser; the combined condenser comprises a full-reflection cambered surface prism arranged right in front of a light source and a cambered surface refraction condenser arranged on the outer edge of the full-reflection cambered surface prism. A total-reflection side wall condenser is arranged on the outer edge of the combined condenser, the shape of the edge of thewhole total-reflection type thick-wall condenser corresponds to the shape of the light-emitting face of an automobile lamp, the light-emitting face of the thick-wall condenser can be changed, when the thick-wall condenser is applied to the lighting device, the light-emitting face can be changed into various shapes, modeling design is facilitated, and the effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a total reflection thick-wall concentrator and a lighting device. Background technique [0002] With the rapid development of automobile lamp technology, in addition to strictly meeting the requirements of laws and regulations, the appearance requirements, especially the lighting effect, are also paid more and more attention. To a certain extent, a beautiful appearance of the lamp can Rapidly improve the visual experience of a car. Therefore, more and more thick-walled parts are used in automobile taillights, which have reached the requirements of transparency, uniformity and changeable shapes. [0003] Although the existing thick-walled parts can meet the requirements of vehicle customers for the shape and appearance of taillights, most of the thick-walled parts have large volume, low efficiency, and can only be used for a single and simple light-emitting surface shape...
