Problems solved by technology

[0009] At present, light-emitting elements are often used as light sources, and when two light sources are used for proper luminosity, the current reflector structure has a structure in which the two light sources are placed adjacent to each other, so there is a problem of heat concentration and low heat dissipation performance
In particular, in recent years, light-emitting elements (LEDs) are often used as lighting devices for vehicles. Since the light-emitting elements are sensitive to heat, the brightness of the light-emitting elements will decrease when the temperature of the light-emitting elements rises, and the service life will also be shortened.
[0010] In addition, in order to dissipate the heat generated in the light source, it is necessary to provide equipment such as a heat sink and a sheet, so there are problems of increasing cost and occupying a large space.
In addition, electric energy is required to run devices such as radiators, fins, etc., which can be a problem causing vehicle fuel inefficiency

Abstract

The embodiments of the invention provide a reflector of a vehicle lighting device. The reflector comprises a first reflecting mirror forming a first ellipse opened to the light source direction, and a second reflecting mirror forming a second ellipse opened to the light source direction and being connected with the first reflecting mirror, wherein the focus of the first ellipse and the focus of the second ellipse are on a same line, and the first ellipse and the second ellipse share a same focus.

Description

Technical field [0001] The present invention relates to a reflection device of a vehicle lighting device, and more specifically, to a reflection device of a vehicle lighting device in which the light concentration and efficiency of the reflection device are improved. Background technique [0002] A vehicle is a means of transportation that uses its own engine to produce power and transmit it to the wheels to carry passengers or goods on the road. Vehicles can be roughly divided into a body that forms an appearance and a chassis that organically connects various devices. The chassis includes: the power transmission device including the engine that becomes the driving force of the vehicle; the steering device; the suspension device; the braking device and other main devices. [0003] The engine is the driving force that drives the vehicle. Most vehicle engines are four-stroke internal combustion engines. A four-stroke internal combustion engine is an internal combustion engine tha...
