Abstract

The utility model discloses an annular luminous LED light source module which comprises a round transparent substrate, two wire holes are formed in the center of the transparent substrate, and a plurality of LED chips are fixed on the transparent substrate and located on a circumference which has the same circle center with the transparent substrate. Metal electrodes are symmetrically fixed on a random diameter of the transparent substrate, the metal electrodes and the LED chips are connected through metal wires and the LED chips are connected through metal wires to form a series-connection structure and a parallel-connection structure, and a fluorescent glue layer wraps the LED chips. According to the annular luminous LED light source module, the light-emitting angle can be substantially increased, light-out efficiency can be improved by more than 50%, and bar-shaped fluorescent glue only coats the LED chips, compared with overall coating of the fluorescent glue, glue can be saved by more than 90%, and production cost is greatly lowered.

Description

A kind of LED light source module of annular luminous

Technical field

The utility model relates to a kind of LED light source module, relates in particular to a kind of LED light source module of annular luminous.

Background technology

Semiconductor light-emitting-diode (LED) illumination is considered to one of field of tool development prospect of 21 century, and it, also will be for promoting energy-saving and emission-reduction, set up conservation-minded society and make major contribution when causing the illumination revolution.

Traditional multi-chip LED light source module, generally adopt aluminium base, copper base or ceramic substrate, and is basic own opaque, so after welding the LED light source particle above the light source module, the bright dipping that can only make progress is larger for design, the luminous intensity distribution restriction of light fixture.

, take bulb lamp as example, when opaque substrate module is directly used in lamp, can only reach the effect of half luminous intensity distribution type (beam angle is less than 180 degree) bulb lamp; Want to realize that (beam angle is spent greater than 180 for accurate full luminous intensity distribution (beam angle is greater than 180 degree) in national and foreign standards and full luminous intensity distribution type, and the luminous flux in 135 ~ 180 degree zones be not less than total light flux 5%) requirement, just must increase secondary optical lens in light fixture, increase the cost of light fixture.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of LED light source module of annular luminous is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of LED light source module of annular luminous, the transparency carrier that comprises a circle, the center of transparency carrier has two wire holes, a plurality of LED chips are fixed on transparency carrier on a circumference with the transparency carrier concentric, the metal electrode symmetry is fixed on arbitrary diameter of transparency carrier, between metal electrode and LED chip and all with metal wire, be connected between LED chip, form the series and parallel structure, fluorescent adhesive layer is wrapped on LED chip.

The beneficial effects of the utility model are that the utility model can significantly increase lighting angle, also can improve light extraction efficiency more than 50%; Simultaneously, only apply the bar shaped fluorescent glue on LED chip, with whole coating fluorescent glue, compare, can save glue material more than 90%, greatly reduced production cost.
