Problems solved by technology

[0003] Compared with traditional incandescent lamps and fluorescent lamps that can emit light at all angles of 360°, the emission angle of LED light is smaller, mostly less than 120°; in this way, when LED replaces traditional light sources in the form of original lamps, it will emit light at spatial positions other than the light-emitting angle The dark area also makes the reflective surface in the original lamp design invalid, which brings certain troubles and difficulties to the promotion and application of LED.

specific example

[0013] refer to figure 1 , figure 2 , the full-angle light-emitting LED light source of the present invention includes two separated brackets 1, and the light-emitting chip 2 is fixed on the crystal-bonding platform on the top of one of the brackets 1, and the P electrode 6 and the N electrode 7 on the surface of the light-emitting chip 2 are respectively bonded The bonding wire 3 is connected to the lead wires 4 on the two brackets, and a layer of sealing glue 5 mixed with phosphor powder is wrapped on the upper part of the bracket, the light-emitting chip 2 , the bonding wire 3 and the lead wire 4 . Specific example: the light-emitting chip selects the Venus type 10*23mil blue light chip of Taiwan Epistar Company, the average particle size of the phosphor used is 13 microns, the outer sealant is aliphatic epoxy resin, and the viscosity at 25 °C is 2800mPa·s. Compared with the common packaging method, this light source raises the fixed position of the chip, and the phosphor...

Abstract

The invention discloses an all-angle luminous light-emitting diode (LED) light source. The light source comprises two separated supports. A luminescence chip is fixed on a die bonding platform on the upper portion of one support; a P electrode and an N electrode on the surface of the luminescence chip are connected with leads on the two supports through bonding wires respectively; and a layer of outer sealing adhesive with fluorescent powder mixed covers the upper portions of the supports and outsides of the luminescence chip, the bonding wires and the leads. The LED light source is capable of achieving all-angle luminescence on space, close to luminescence forms of traditional light sources and capable of facilitating light source substitution and lamp design.

Description

technical field [0001] The invention belongs to the technical field of electric light sources. Specifically, the invention relates to an LED light source, especially an LED light source that emits light from all angles. Background technique [0002] Because of its small size, fast response, long life, high reliability, low power consumption, environmental protection and other advantages, LED has been widely concerned, and is considered to be the fourth-generation lighting source that will replace incandescent lamps and fluorescent lamps. [0003] Compared with traditional incandescent lamps and fluorescent lamps that can emit light at all angles of 360°, the emission angle of LED light is smaller, mostly less than 120°; in this way, when LED replaces traditional light sources in the form of original lamps, it will emit light at spatial positions other than the light-emitting angle The dark area also makes the reflective surface in the original lamp design invalid, which brin...
