Description

technical field

[0001] The invention relates to the technical field of LED light source module substrates, in particular to an improvement technology for LED chip light source module substrates. Background technique

[0002] At present, the more common LED chip light source module substrates on the market do not have a reflective surface specially, and some of them have been treated with a reflective surface. The proportion of the reflective surface to the light surface is not large, and the treatment effect of the reflective surface is not ideal. The light extraction efficiency is limited, and the external lead pads of common LED chip light source module substrates are all on the side of the light output side of the finished product, which affects the overall light output effect of the finished product, and it is inconvenient to apply it in the process of making lamps.
