Abstract

This invention discloses one white LED sealed dissipation structure, which comprises Two metal lead legs with one top as rack cup with blue lighting crystal and fluorescence glue layer stretching out two wires connected to two lead legs, wherein, the two racks top ends are sealed with transparent resin; the top and down sides of crystal are set with one dissipation glue layer. The invention adopts the above structure to get two dissipation glue layer in work for lead legs rapidly and then through rack to outside to make the LED light work under temperature of 65 degrees and fluorescent powder life of 40000 hours.

Description

technical field

[0001] The invention relates to an LED package structure, in particular to a white light LED package conduction and heat dissipation structure. Background technique

[0002] As a light source, LED has many advantages such as low energy consumption, low calorific value, and long service life, and has been more and more widely used in lighting and decorative lamps. Among them, the emergence of white LEDs has enabled the application of high-brightness LEDs to enter the market of high-efficiency lighting sources.

[0003] Existing white light LEDs use blue light-emitting crystals and phosphors to cooperate and then use the principle of lenses to emit white light required by the naked eye. However, the current white LED lamps mostly use the structure of white LED arrays to provide the overall luminous brightness of the lamps. Therefore, although the calorific value of a single white LED is low, a large number of white LED devices are used in relatively sealed and...
