Abstract
The utility model discloses a high luminous efficiency LED light source module which includes a blue light chip and a substrate. The substrate is provided with a groove. The internal wall of the groove is coated with a light reflecting layer. The light reflecting layer is coated with a red phosphor layer. The blue light chip is packaged in the groove. Through arranging the groove and arranging the chip in the groove, the glue dispensing becomes more convenient; and through arranging the light reflecting layer and the red phosphor layer, the luminous efficiency of a product is greatly improved.
Description
Technical field
The utility model relates to a kind of led light source module, especially relates to a kind of led light source module of high light efficiency.
Background technology
Along with the LED technology rapid development, LED almost has application, especially white light LEDs in industry-by-industry; Because it has energy-saving and environmental protection, advantage that volume is little; Receive whole world user's favor, obtained in recent years developing rapidly, the LED encapsulation technology is also in continuous progress simultaneously; Packing forms is very diversification also, and COB is exactly wherein a kind of at present.Traditional COB package module generally all is directly that chip is solid brilliant on substrate, and this packing forms thermal resistance is bigger, and the light efficiency of generation is unsatisfactory, compared to traditional incandescent lamp certain gap is arranged still, and fluorescent glue flows bad control easily during point glue.
The utility model content
The utility model provides the led light source module of a kind of some glue convenience, high light efficiency in order to overcome the deficiency of prior art.
To achieve these goals; The utility model adopts following technical scheme: a kind of led light source module of high light efficiency; Comprise blue chip and substrate, said substrate is provided with groove, and the inwall of groove is coated with reflector layer; Be coated with one deck red fluorescence bisque on the reflector layer, said blue chip is packaged in the said groove.
As preferably, be coated with one deck yellow fluorescence bisque on the said red fluorescence bisque.
As preferably, the thickness of said red fluorescence bisque is 0.5-0.7mm.
As preferably, the thickness of said yellow fluorescence bisque is 0.4-0.7mm.
As preferably, said substrate is an aluminum base plate.
As preferably, said upper surface of base plate is coated with the radiation enamelled coating.
The utlity model has following advantage: the utility model is through being provided with groove, and chip is located in the groove, and some glue is convenient, and reflector layer and red fluorescence bisque are set, and makes product have high light efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1, a kind of led light source module of high light efficiency comprises blue chip 1 and aluminum base plate 2, has groove 3 on the substrate 2, and blue chip 1 is packaged in the groove 3.The inwall of groove 3 is coated with reflector layer, is coated with one deck red fluorescence bisque 4 on the reflector layer, is coated with one deck yellow fluorescence bisque 5 on the red fluorescence bisque 4; The thickness of red fluorescence bisque 4 is 0.5-0.7mm, preferred 0.5mm.The thickness of yellow fluorescence bisque 5 is 0.4-0.7mm, preferred 0.5mm.Substrate 2 upper surfaces are coated with the radiation enamelled coating, have improved radiating efficiency greatly, have prolonged the useful life of LED.
Through groove is set, the inwall of this groove scribbles reflector layer, is equivalent to a good reflector, and light source is effectively reflected, and has improved light efficiency greatly; The effect of red fluorescence bisque and yellow fluorescence bisque makes blue chip send soft white light.And after groove is set, help carrying out of glue more, do not worry that fluorescent glue can arbitrarily flow.
