Abstract

The utility model discloses a novel high-power LED packaging structure which comprises a heat radiation substrate, a high-power LED and a reflection cup. The high-power LED is disposed on the heat radiation substrate. A focusing lens is disposed on the surface of the high-power LED. A circular end of the reflection cup covers the focusing lens and is fixed on the heat radiation substrate. A large circular end of the reflection cup is provided with microcrystalline glass, wherein fluorescent powder is uniformed doped in the microcrystalline glass. According to the novel high-power LED packaging structure, since the fluorescent powder is doped in or coated outside the glass surface, the uniformity of the fluorescent powder is improved, and the packaging efficiency is also improved. In addition, the number of the optical interfaces in the luminous directions of the LED is reduced, which is also an effective measure for improving the luminous efficiency.

Description

A kind of Novel high-power LED packaging structure
Technical field
The utility model relates to LED lamp field, relates in particular to a kind of Novel high-power LED packaging structure.
Background technology
In prior art, the effect of fluorescent material is photochromic compound, forms white light.Its characteristic mainly comprises granularity, shape, luminous efficiency, conversion efficiency, stability (heat and chemistry) etc., and wherein, luminous efficiency and conversion efficiency are crucial.Research shows, along with temperature rises, fluorescent material quantum efficiency reduces, and bright dipping reduces, and radiation wavelength also can change, thereby causes the variation of white light LED color temperature, colourity, and higher temperature also can be accelerated the aging of fluorescent material.Reason is that fluorescent coating is to be formed by epoxy or silica gel and fluorescent material allotment, and heat dispersion is poor, and when being subject to the radiation of purple light or ultraviolet light, easily occurrence temperature quencher and aging, reduces luminous efficiency.
Traditional fluorescent powder coated mode is that fluorescent material is mixed with casting glue, is then coated on chip.Owing to cannot the applied thickness of fluorescent material and shape accurately being controlled, cause emergent light color inconsistent, there is inclined to one side blue light or inclined to one side gold-tinted.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Novel high-power LED packaging structure.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of Novel high-power LED packaging structure, comprise heat-radiating substrate, great power LED, reflector, described great power LED is located at above heat-radiating substrate, on described great power LED surface, arrange a condenser lens, reflector roundlet end shield is lived condenser lens, and is fixed on heat-radiating substrate, and the large nose circle of described reflector is provided with devitrified glass.
The utility model has the advantages that: by by mixing in fluorescent material or being applied to glass surface outward, not only improved the uniformity of fluorescent material, and improved packaging efficiency.In addition, reducing the optical interface number of LED light direction, is also the effective measures that improve light extraction efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is elaborated.
Fig. 1 is the utility model high-power LED encapsulation structure schematic diagram.
Embodiment
As shown in Figure 1, a kind of Novel high-power LED packaging structure, comprise heat-radiating substrate 3, great power LED 5, reflector 2, described great power LED 5 is located at above heat-radiating substrate 3, on described great power LED 5 surfaces, arrange a condenser lens 4, reflector 2 roundlet end shields are lived condenser lens 4, and are fixed on heat-radiating substrate 3, the large nose circle of described reflector 2 is provided with devitrified glass 1, the interior fluorescent material that is mixed with uniformly of described devitrified glass 1.
The foregoing is only preferred implementation of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
