Description

technical field

[0001] The invention belongs to the technical field of auto lamp spare parts, and in particular relates to a lamp shade for an automotive headlamp. Background technique

[0002] With the rapid development of the automobile industry, while people are pursuing comfort and ease of handling, more and more attention has been paid to the overall safety, energy saving and environmental protection of automobiles. In this regard, the headlights of automobiles now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; The airtight form is buckled on the headlight. When the headlight is in the lighting state, the airtight environment it is in will generate a higher temperature due to heat accumulation. This higher temperature is not only easy to burn in the car. Fog is generated inside the lamp, which affects the lighting effect, and it is easy to cause the parts in the car lights t...
