LED daytime driving lamp

Abstract

The invention relates to an LED daytime driving lamp. The LED daytime driving lamp is mainly formed by assembling lamp glass, a lamp housing, a mirror, self-tapping screws, an LED module and a power line in a sealed manner, and is characterized in that the mirror is connected with the lamp glass through the self-tapping screws; the mirror is in a zigzag shape with the angle ranging from 60 degrees to 90 degrees; the LED module is composed of an LED circuit board, LED lamp beads, an LED cooling aluminum plate, an LED drive board, self-tapping screws, an LED power line and an LED installation support. By means of the LED daytime driving lamp, the brightness of daytime driving lamps is improved, the requirement of the regulation ECE R87 is met, a striking vision effect is achieved for drivers, and the safety performance of driving is improved; the LED light source independent type aluminum substrate cooling structure is adopted, the service life of the LED daytime driving lamp is prolonged, and the maintenance cost is reduced; and the form design of independent type single lamps or combined lamps is adopted, lamp structures can be reasonably arranged under the condition that the size of the lamp assembling space is limited, and the lamp space size is reduced.

Description

technical field [0001] The technology of the present invention belongs to the field of automobile engineering, and in particular relates to an LED 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 application of ...

AI Technical Summary

Problems solved by technology

However, the current LED daytime running lights generally have the following problems: (1) Due to the high luminous intensity of the LED light source, it is easy to produce dazzling adverse effects, which affects the visual effect and safety performance of the driving car, and greatly reduces the safety of driving. (2) When the size of the lamp assembly space is limited, the layout of the built-in light source of the lamp is unreasonable, and the arrangement of the lamps is chaotic, which increases the space occupied by the lamps and affects the appearance of the lamps; (3) in the assembly of lamps In the case of limited space size, the structural design of the LED light source cooling plate is unreasonable, and the heat dissipation problem of the LED light source will lead to functional failures from time to time, which will reduce the service life of the daytime running lights and increase the maintenance cost of the LED daytime running lights
