Problems solved by technology

Therefore, the light-emitting area of ​​the car light is very small to facilitate the light distribution design. At present, the light-emitting area of ​​the ordinary LED light is too large in terms of the power of the car light, so it is necessary to add additional optical accessories to the light, such as lenses or reflective bowls. etc. These lenses or reflective bowls are usually complex special-shaped structures to meet the light emission requirements, which makes the overall structure of the lamps complicated, the lamp assembly is very large, and it is not convenient for vehicle shape design

Abstract

The invention relates to an inverted LED car lamp, which is characterized by comprising a substrate, a conductive circuit layer, a linking circuit layer, a box dam glue, chip units and a side seam glue; the top part of the substrate is fixedly arranged at the conductive circuit layer, the conductive wire has a cycle of box dam glue; several chip units are arranged on the conductive circuit layer in the box dam glue at intervals; a gap between the box dam glue and every chip unit is filled with the side seam glue; every chip unit comprises an inverted LED chip, the bottom part of every inverted LED chip is welded and fixed with the conductive circuit layer, the top part of every inverted LED chip is bonded and fixed with a cover plate. The invention can be widely applied to the manufacturing process of the car lamp.

Description

technical field [0001] The invention relates to a flip-chip LED vehicle lamp, and relates to the technical field of LED vehicle lamps and vehicle accessories. Background technique [0002] LED (Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. With the rise of LED, the application field of LED lighting has become wider and wider. In recent years, LED lighting has been applied to various vehicle lighting. For vehicle headlights, it is required to have a long range when the high beam is high, forming a strip-shaped spot, and when the low beam is low, a light and dark cut-off line is required. Therefore, the light-emitting area of ​​the car light is very small to facilitate the light distribution design. At present, the light-emitting area of ​​the ordinary LED light is too large in terms of the power of the car light, so it is necessary to add additional optica...
