Description

Lamp with light blocking and reflecting structure

Technical Field

The utility model relates to a car light grading technical field, in particular to lamps and lanterns with be in light and reflection of light structure.

Background

In recent years, efficient and durable LED light source type lamps are increasingly used in vehicles. The main forms of the LED direct lighting device are a projection type and a reflection type, the reflection type is low in cost and changeable in shape compared with the projection type, but stray light generated by direct light of the LED has adverse effects on the whole lighting effect. Therefore, the light shielding structure is required to be added, and the light shielding structure is generally thought to be added on the heat sink, and can adopt the following forms: (1) a light blocking structure is directly made on the radiator, so that when a PCB (printed circuit board) of a light source is installed, the risk that the radiator is locally visible is generated; (2) the form of newly-increased lens hood on the radiator just so need give the lens hood headspace, leads to the whole space grow of lamps and lanterns, and the cost is higher moreover.
