The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is the schematic diagram according to the disassembled form of the nanocrystalline illuminating lamp of phase the utility model embodiment; And Fig. 2 is the schematic diagram according to the assembled state of the nanocrystalline illuminating lamp of the utility model embodiment.
As shown in Figure 1, this nanocrystalline illuminating lamp comprises: reflector 12; Led light source 14 is arranged at the bottom of described reflector 12; And nanocrystalline fluorescence blob of viscose 13 is arranged at the bottom of described reflector 12 and is positioned at the top of described led light source 14.
Preferably, above-mentioned nanocrystalline illuminating lamp comprises: cloche 11 is arranged at the top of described reflector 12.
Preferably, above-mentioned nanocrystalline illuminating lamp comprises: cloche snap ring 10 is arranged at the outside of described cloche 11.
Preferably, above-mentioned nanocrystalline illuminating lamp comprises: heat dispersion heat sink 15, be arranged at the inboard of described reflector 12, wherein, cloche snap ring 10 and the clamping mutually of described heat dispersion heat sink 15.
Preferably, above-mentioned nanocrystalline illuminating lamp comprises: lamp holder 16 is connected with described heat dispersion heat sink 15.
Preferably, between described heat dispersion heat sink 15 and described reflector 12, has separation layer 18.
Preferably, between described heat dispersion heat sink 15 and described reflector 12, also be provided with insulating materials.
In the utility model, by the centre of luminescence and uptake zone appropriateness are separated, the novel red light-emitting material of this quantum dot has at first solved the problem of the self-absorption of fluorescent material, so, this material is named as " low self-absorption quantum dot " (English for low-reabsorption quantum dots, as to abbreviate LR-dots as).Use this material to replace existing red fluorescence powder and well solved low this guardian technique difficult problem of at present warm white LEDs light efficiency, simultaneously the colour rendering index problem low and that the black body radiation departure degree is big of original cold white LEDs is improved.
The red quantum dot of the nanocrystalline illuminating lamp in the utility model has Gao Lan-ruddiness transformation efficiency, and is low to the absorption of green-yellow light, avoided the reduction significantly of light efficiency like this when cold white LEDs being converted into warm white LEDs.The emission peak of this novel red luminescent material is narrower simultaneously, sends infrared ray hardly, and the light efficiency of also having avoided causing because sending infrared ray reduces.
Fig. 3 is the schematic diagram according to the luminance of the nanocrystalline illuminating lamp of the utility model embodiment.
As shown in the figure, of the present utility model can well solve LED luminous by cold white-warm white conversion process in light efficiency lose this a great problem, produce high light efficiency, high light quality, long-life warm white solid-state illumination device.
The special structure design that the PAR lamp is had in the utility model can be effectively spatially separated nanocrystalline or fluorescent material and led light source, thus the temperature of nanocrystalline or fluorescent material when being reduced in PAR lamp operate as normal.Simultaneously reflector and heat sink structural design make reflector and heat sink between form air barrier (can also filling heat insulator or make heat insulating member) with heat-insulating material thus prevent that the heat sink heat that distributes is directed at reflector and is directed at nanocrystalline again or the fluorescent material carrier.Owing to the rising along with temperature of the quantum/conversion efficiency of nanocrystalline or fluorescent material descends, this design can keep nanocrystalline or fluorescent material quantum efficiency at low temperatures, thereby makes this PAR lamp compare with traditional LED PAR lamp, has the characteristics of high light flux.
As can be seen from the above description, the utility model can improve the radiating efficiency of led light source in the nanocrystalline illuminating lamp.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
