Abstract

The utility model discloses a circular surface-type luminescent LED light source module, which comprises a circular transparent substrate, two wire holes are opened in the center of the transparent substrate, and a plurality of LED chips are fixed on the transparent substrate and connected with the transparent substrate. On several circles with the same center, the metal electrodes are symmetrically fixed on any diameter of the transparent substrate. The metal electrodes and the LED chips and the LED chips are connected with metal wires to form a series and parallel structure. The fluorescent glue layer is wrapped in the LED. On the chip; the LED light source module of the utility model can emit light to the whole space angle at the same time when it is powered on, which not only greatly increases the light angle, but also improves the light output efficiency by more than 50%. It can realize flexible light distribution design when used in lamps, and To save the cost of the radiator, there is a wire hole in the middle of the module, which is convenient for wiring in use.

Description

The LED light source module that a kind of rounded face formula is luminous

Technical field

The utility model relates to a kind of LED light source module, relates in particular to the luminous LED light source module of a kind of rounded face formula.

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 above the light source module, welding the LED light source particle, 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 the full luminous intensity distribution of standard (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 in light fixture, increase secondary optical lens, 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, provides a kind of rounded face formula luminous LED light source module.

The purpose of this utility model is achieved through the following technical solutions: the LED light source module that a kind of rounded face formula is luminous, it comprises the transparency carrier of a circle, the center of transparency carrier has two wire holes, a plurality of LED chips are fixed on transparency carrier on the several circumference with the transparency carrier concentric, the metal electrode symmetry is fixed on the 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, LED light source module of the present utility model can be simultaneously luminous to total space angle when energising, not only significantly increase lighting angle, also can improve light extraction efficiency more than 50%, for light fixture, can realize luminous intensity distribution design flexibly, and save the cost of radiator, in the middle of module, have wire hole, the trace arrangements in easy to use.

The accompanying drawing explanation

Fig. 1 is the luminous LED light source module schematic diagram of the utility model rounded face formula;

In figure, transparency carrier 1, LED chip 2, metal wire 3, wire hole 4, metal electrode 5, fluorescent adhesive layer 6.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

As shown in Figure 1, the LED light source module that rounded face formula of the present utility model is luminous, the transparency carrier 1 that comprises a circle, the center of transparency carrier 1 has two wire holes 4, a plurality of LED chips 2 are fixed on transparency carrier 1 on the several circumference with transparency carrier 1 concentric, metal electrode 5 symmetries are fixed on arbitrary diameter of transparency carrier 1, between metal electrode 5 and LED chip 2 and all with metal wire 3, be connected between LED chip 2, form the series and parallel structure, fluorescent adhesive layer 6 is wrapped on LED chip 2.

After LED light source module of the present utility model adopts said structure, can be simultaneously luminous to total space angle when energising, not only significantly increase lighting angle, also can improve light extraction efficiency more than 50%, for light fixture, can realize luminous intensity distribution design flexibly, and save the cost of radiator; Have wire hole in the middle of module, the trace arrangements in easy to use.
