LED light guide daytime running lamp

Abstract

The invention relates to an LED light guide daytime running lamp which is composed of an LED light source, an LED driving board, a light guide, lamp glass and a lamp shell through assembling in a sealed mode. The LED light guide daytime running lamp further comprises an LED power line, a light guide mounting rack, a light guide fixing frame, a light guide decorative plate and a self-tapping screw. The LED light source is mounted to the LED driving board. The light guide is installed on the light guide mounting rack. The light guide mounting rack is connected with the light guide fixing frame. The light guide fixing frame is connected with the light guide decorative plate, the light guide and the light guide mounting rack. The light intensity of a light band formed through the design of an LED light guide structure meets the required value of the regulation ECE R87, the lamp shell and the lamp glass in the lamp are assembled and bonded with automotive glue, and the characteristics of sealing performance and waterproof performance are achieved. The LED lamp has the function that an automobile running in daytime or in rainy weather, foggy weather and the like can be better recognized by other users on a road, the traveling safety is improved, and the possibility of traffic accidents is decreased.

Description

technical field [0001] The technology of the present invention belongs to the field of automobile engineering, and in particular relates to an LED light guide daytime running light. Background technique [0002] Daytime running lights are special lights that are automatically turned on when the car engine is started. Its function is to allow other road users to better perceive and identify when driving in daytime or in rainy and foggy weather. According to official statistics, the installation of daytime running lights on vehicles can reduce vehicle accidents by 12.4%, and also reduce the probability of death in car accidents by 26.45%. Early daytime running lights used halogen bulb light sources, which had the disadvantages of short service life and high power consumption; with the emergence of LED green light sources, most daytime running lights use LED configurations, which have long life, small size, good stability, and fast response. and other characteristics. The app...

AI Technical Summary

Problems solved by technology

At present, the LED daytime running lights on the market generally have the following problems: (1) They are designed in the form of combination lights, and the structure and layout of the lamps are unreasonable, and the lamps occupy a large space, resulting in a large volume of the daytime running lights, reducing the The aesthetics of its appearance; (2) The structure design of the light guide combination is unreasonable, and the number of LED lamps is large, which increases the difficulty of LED assembly, and the assembly of multiple LEDs will cause problems such as poor welding, which will affect the quality of LED daytime running lights; ( 3) The use of multiple lamp bead structures has the problem of difficult LED heat dissipation, which greatly reduces the service life of LED daytime running lights; (4) The design of the LED light guide is not designed according to the principle of total reflection, which makes the external visual effect of the lights poor. Reduced driving safety performance
