Description
Technical field
The utility model relates to light-emitting device.
Background technology
At first, need explanation, white light is a kind of complex light, need be made up of jointly multiple spectrum.From the spatial distribution angle, three kinds of formula are arranged, first kind of formula, blue light+gold-tinted=white light; Second kind of formula, blue light+green glow+ruddiness (+gold-tinted)=white light; The third formula, blue light+gold-tinted+ruddiness=white light.
Japan day inferior (Nichia) company obtains the White-light LED illumination license the earliest, and the patent No. is US5998925, and this patent can be in brief: blue-ray LED light source+yellow fluorescent powder=white LED light source, i.e. first kind of mode.Mitsubishi Chemical is in the patent application of US2007007494A1 at publication number, adds green emitting phosphor and red fluorescence powder with formation white light, the i.e. second way at yellow fluorescent powder.Further, other companies still adopt second kind of formula to apply for a patent, but the generation of green glow and ruddiness is to be produced by green LED and red LED, but not by the fluorescent material generation that is stimulated.
In the prior art, the light of light source all is directly to see through fluorescent material to penetrate, yet the light mixed effect that this light source penetrates is even inadequately.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and light-emitting device is provided, through once or repeatedly irreflexive light in reflection chamber, each other mix the back and penetrate, make that the light mixing of penetrating is more even.
The utility model solves the technical scheme that its technical problem adopted: light-emitting device; Comprise at least two luminous submodules; Between luminous submodule, form positive all orientating reflex cavitys of reflection chamber and each luminous submodule, described each luminous submodule includes substrate and reflecting layer, and fixes in regular turn between substrate and the reflecting layer; Wherein, the reflecting layer is as the positive orientating reflex cavity of luminous submodule; At least one luminous submodule is provided with at least one led light source; Described led light source is fixed on the described substrate and the orientating reflex cavity; At least one luminous submodule is provided with the fluorescence conversion layer; Described fluorescence conversion layer is coated on the reflecting layer, and at least one luminous submodule comprises at least one transmission region.
Described reflecting layer is coated with the fluorescence conversion layer on the subregion.
Described led light source sends a kind of light of color at least, and said led light source sends the light wavelength scope at 200nm～700nm.
Be placed with circuit layer on the described substrate, the electrode of described led light source is connected with described circuit layer.
The beneficial effect of the utility model is:
The first, through once or repeatedly irreflexive light in reflection chamber, each other mix the back and penetrate, make that the light mixing of penetrating is more even;
Second; Because reflection chamber carries open transmission region,, utilize air transmitted to dispel the heat so air-flow can quicken to flow in reflection chamber; On the basis of mixed light, saved heavy Aluminium Radiator; The led light source temperature is descended, reach and improve the performance and the purpose in life-span, practiced thrift cost simultaneously;
The 3rd, the fluorescence conversion layer does not directly contact with the PN junction of led light source, so the temperature of fluorescence conversion layer can not rise along with the temperature of led light source and improve.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain; But the light-emitting device of the utility model is not limited to embodiment.
