Abstract
An illuminating device comprises a laser and a package arranged on one side of the laser, wherein fluorescent powder is arranged in the package. The illuminating device has high photoelectric conversion efficiency.
Description
Technical field
The present invention relates to a kind of lighting device, relate in particular to a kind of laser illuminator system.
Background technology
Than traditional light emitting source, light emitting diode (Light Emitting Diode, LED) there is the advantages such as lightweight, volume is little, it is low to pollute, the life-span is long, it is as a kind of novel light emitting source, be applied to more and more in the middle of each field, as street lamp, traffic lights, signal lamp, shot-light and ornament lamp etc.
But, light emitting diode in the course of the work by the electric energy of input except converting to the wider luminous energy of frequency spectrum, also produce heat energy, and its light sending is easily interfered in communication process, but also to collect the careless and sloppy light that it sends by secondary optical system, therefore, its photoelectric transformation efficiency is not high.
Summary of the invention
In view of this, the present invention aims to provide the lighting device that a kind of photoelectric transformation efficiency is higher.
Lighting device comprises a laser and is arranged at a packaging body for this laser one side, in this packaging body, is provided with fluorescent material.
Lighting device of the present invention is by adopting laser as light source, and its light sending has high directivity, and is difficult for while propagating in air or other medium being interfered; And laser almost all converts the electric energy of input to luminous energy, and therefore this lighting device has higher photoelectric transformation efficiency.

The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
As shown in Figure 1, the lighting device 1 that first embodiment of the invention provides, it comprises that a laser diode 10, is arranged at the packaging body 20 of laser diode 10 1 sides and is located at the reflecting layer 30 on packaging body 20.
The luminous frequency spectrum of laser diode 10 is narrower, and its light sending has high directivity, and is difficult for while propagating in air or other medium being interfered.And laser diode 10 almost all converts the electric energy of input to luminous energy, the heat of its generation is also less, therefore has higher photoelectric transformation efficiency.In the present embodiment, the light that laser diode 10 sends is blue light.
In the time that lighting device 1 is worked, the blue light that laser diode 10 sends is after the left surface 24 of packaging body 20 is incident to the inside of packaging body 20, yellow fluorescent powder in packaging body 20 21 is excited, after being excited, yellow fluorescent powder 21 produces gold-tinted, meanwhile, the transmission path that is incident to packaging body 20 blue lights is destroyed by yellow fluorescent powder 21 and directive all directions form white light with yellow light mix.Part white light penetrates from the bottom surface 23 of packaging body 20; End face 22 and the right flank 25 of another part white light directive packaging body 20, under the interreflection effect in reflecting layer 30, this another part white light finally all penetrates from the bottom surface 23 of packaging body 20, thereby forms linear light field.
In the present invention, by adopting laser diode 10, its light sending has high directivity, and is difficult for while propagating in air or other medium being interfered; And laser diode 10 almost all converts the electric energy of input to luminous energy, and the heat of its generation is also very little, therefore has higher photoelectric transformation efficiency.
Figure 2 shows that the lighting device 1a that second embodiment of the invention provides, the lighting device 1 of itself and the first embodiment is similar, its difference is only, laser diode 10 is located at the lower left of packaging body 20, and it is curved that reflecting layer 30 covers at end face 22 1 sides and its cross section of packaging body 20.So, in the light that laser diode 10 is excited by fluorescent material 21, some directly penetrates from the bottom surface 23 of packaging body 20; Another part directive reflecting layer 30, and then under the 30 interreflection effects of the reflecting layer of arc, finally penetrate from the bottom surface 23 of packaging body 20, thereby form spherical light field.
Understandable, laser diode 10 also can send the light of other color except blue light, and fluorescent material 21 also can be the fluorescent material of non-yellow, and the light that laser diode 10 sends is excited the mixed light of rear another color of generation by fluorescent material 21.
Technology contents of the present invention and technical characterstic disclose as above, but those skilled in the art still may be based on teaching of the present invention and announcements and made all replacement and modifications that does not deviate from spirit of the present invention.Therefore, protection scope of the present invention should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present invention and modifications, and is contained by appended claim.
