Light-emitting diode with light distributing function and preparation method thereof

Abstract

The invention provides a light-emitting diode with a light distributing function and a preparation method thereof. The light-emitting diode comprises a heat-radiating panel (1), LED chips (2), a fluorescent powder layer (3), a silica gel packaging layer (4) and electrode leads (5), wherein the LED chips (2) are fixed on the heat-radiating panel (1) and are arranged in an array way; the fluorescent powder layer (3) is coated on the heat-radiating panel (1) and completely covers the LED chips (2); the silica gel packaging layer (4) is coated on the fluorescent powder layer (3); the electrode leads (5) are connected with electrodes of the LED chips (2) and are exposed to the outside; and the silica gel packaging layer (4) is formed by mixing silica gel, nano or silica gel and micron particles. In the light-emitting diode, nano or micro particles are added in the silica gel packaging layer, thereby enlarging the divergence angle, increasing the light-emitting area and enabling the light to be milder.

Description

【Technical field】 [0001] The invention relates to a light-emitting diode and a preparation method thereof, in particular to a light-emitting diode with a light distribution function and a preparation method thereof. 【Background technique】 [0002] In recent years, the technology of LED has developed rapidly. The improvement of its luminous brightness and the extension of its life, coupled with the substantial reduction of production costs, have made LED quickly enter the field of lighting and enter the stage of practical application. LED is a solid-state semiconductor device that can directly convert electricity into light. It is an ideal light source to replace traditional light sources. It has a wide range of uses and many advantages, such as: small size, low power consumption, and long service life. Long, high brightness, low heat, environmental protection, energy saving, durable, etc. [0003] LED packaging adopts corresponding dimensions according to different applicat...
