Abstract

The invention discloses a linear LED light source, a linear LED lamp and a manufacturing method for the linear LED light source. The linear LED light source comprises a metal substrate, multiple LED wafers, at least one coffer and at least one packaging part used for covering and packaging the LED wafers. The LED wafers installed on the metal substrate are connected in series. The coffer is fixed to the metal substrate. The coffer surrounds the peripheries of the LED wafers. The linear LED light source and the linear LED lamp are good in light emitting quality and low in production cost.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a linear LED light source, a linear LED lamp and a preparation method of a linear LED light source. Background technique [0002] LED (light-emitting diode) is a solid-state semiconductor device. The existing LED light source generally consists of a bracket with leads, a semiconductor chip placed on the bracket, and a packaging material (such as fluorescent silicone or epoxy resin) that seals the chip around. ), the semiconductor wafer contains a P-N structure. When the current passes, electrons are pushed to the P region, where the electrons recombine with holes, and then emit energy in the form of photons to achieve lighting purposes. The wavelength of light It is determined by the material forming the P-N structure. Compared with traditional incandescent lamps and fluorescent energy-saving lamps, light-emitting diodes have many advantages such as energy saving and envi...
