Long-life LED lamp light-emitting unit and long-life LED lamp

Abstract

The present invention provides a long-life LED lamp light-emitting unit and a long-life LED lamp. The long-life LED lamp light-emitting unit comprises a pedestal and LED bare crystals, wherein the pedestal comprises a plurality of transparent bearing substrates which are arranged at intervals and in parallel, multiple LED bare crystals are bonded between every two bearing substrates which are adjacent, the multiple LED bare crystals can be connected through a lead, the pedestal is coated with fluorescent glue layers so that lights emitted by the LED bare crystals go out of the pedestal after passing through the fluorescent glue layers. The fluorescent glue layers can be separated from connection points of gold threads, thus the tension force to the gold threads caused by thermal expansion and cold contraction of the fluorescent glue layer is avoided, and the phenomenon that the connection point is broken due to the tension force and an arc is generated to burn the crystal is avoided. According to the above structure of the long-life LED lamp light-emitting unit, non-uniform stress of the gold thread can be reduced; through multiple layers of light emitting bodies and the multiple layers of light emitting units, in the case of the same light-emitting efficiency, heat dissipation area is increased, thereby prolonging the service life of an LED lamp.

Description

technical field [0001] The present invention relates to an LED lamp, in particular to a long-life LED lamp light-emitting unit and a long-life LED lamp. Background technique [0002] At present, the LED lamp mainly includes a shell and a luminous body. The luminous body has a base on which the LED bare die is arranged, and the base is covered with a fluorescent glue layer, but the fluorescent glue directly covers the surface of the LED bare die. When the lamp is working, the heat of the LED bare die is directly transferred to the fluorescent glue layer, and the fluorescent glue layer is thermally expanded and pulls the gold wire on the LED bare die, and the gold wire connection point on the LED bare die is relatively weak. At this time, the connection point may be pulled apart, resulting in a state of being in a state of being far away, and an arc will be generated, which will affect the service life of the lamp body.

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the gold wire of the LED light source module is disconnected from the connection point between the gold wire and the bare LED crystal due to thermal expansion and contraction of the adhesive layer, and an arc is generated to burn the bare LED crystal to black, which eventually leads to the service life of the LED lamp. question
