Abstract
Description
technical field
[0001] The invention relates to a fixing structure, in particular to a novel chip fixing structure for fixing a light-emitting chip on a lead frame or a chip carrier. Background technique
[0002] At present, the fixation of light-emitting chips is achieved by using traditional lead frames or chip carriers, and the bottom of traditional lead frames or chip carriers is a flat die-bonding area as a whole, but since the thickness of the light-emitting chips is not Similarly, when the light-emitting chip is fixed in the plane die-bonding area of ββthe traditional lead frame or chip carrier and conducts light, the light-emitting angles between the light-emitting chips are not the same, resulting in differences in the light-emitting angles between the light-emitting chips. If it is too large, it will cause uneven light mixing between the light emitting chips after emitting light.
[0003] Take the traditional 3-4 element material light-emitting chip and GAN materi...
