Abstract

The invention discloses a light guide grading LED protection cover structure and a light guide grading automotive lamp thereof, relates to arrangement of a common car lighting or signal device, in particular to the light guide grading LED protection cover structure for protecting a light guide grading automotive lamp LED chip and an automotive lamp using the light guide grading LED protection cover structure. The light guide grading automotive lamp comprises a light guide for automotive lamp grading and a circuit board mounted with an LED chip in an adhering manner; an LED protection cover surrounding the LED chip is equipped on the LED chip side of the circuit board; the height H of the LED protection cover is equal to the sum of the height h of the LED chip and the minimum protective gap d; the length and width of the LED protection cover are greater than those of the LED chip and less than those of a light inlet surface of the light guide to ensure that the light inlet surface of the light guide does not touch the semiconductor chip of the LED chip under any condition and to protect the semiconductor chip of the LED chip from being damaged, so that the light guide collides with the LED chip due to automotive vibration or deformation of the light guide to finally cause the risk that the automotive lamp is integrally scrapped.

Description

technical field [0001] The invention relates to the arrangement of general vehicle lighting or signal devices, in particular to a light guide light distribution LED protective cover structure for protecting the light guide light distribution LED chip of an automotive lamp, and an automotive lamp using the light guide light distribution LED protective cover structure. Background technique [0002] With the popularity of LED automotive lamps, light guide light distribution is becoming more and more important in the design of automotive lamps. The Chinese utility model patent "A light-guide LED position light" (utility model patent number: ZL201520211196.9 authorized announcement number: CN204629296U) discloses a light-guide LED position light, including an LED module, and the LED module is installed on the There are LED particles, and the LED module is connected with a light pipe at a position corresponding to the LED particle. The light pipe is installed in a light guide supp...
