Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Laser, without the structure of electric lighting system, is shown in Fig. 1.The laser that blue light LD1 sends is after coupling mirror 2 is coupled, laser beam is focused on by focus lamp a3 and is coupled into Transmission Fibers 4 incidence end, transmit after a segment distance through Transmission Fibers 4 and export from output, Output of laser exports with class directional light after focus lamp b6, be radiated on the fluorescent material coat on fluorescent material plummer 7 and inspire fluorescence, because this fluorescent material coat is positioned at the focus place of this reflector 5, penetrate so the fluorescence inspired and blue light diffuse reflection to reflector 5 form white light with the plate glass 8 of class directional light through front.
Coupling head is directly inserted into light-emitting window by the blue light LD of some packing forms, sees Fig. 2.Transmission situation after what blue light LD sent be optically coupled into optical fiber is identical with said process.
During fluorescent material coat on described blue-light excited fluorescent material plummer 7, all produce fluorescence at fluorescent material coat outer surface 7.1, fluorescent material coat inner surface 7.2 respectively, also have blue light through fluorescent material coat.The reflection mode of fluorescence produced at fluorescent material coat outer surface 7.1 is as above-mentioned implementation process, and fluorescent material coat inner surface 7.2 produce fluorescence and through blue light synthesize white light, directly through transparent fluorescent material plummer 7, transferred out by plate glass 8, see Fig. 3.
Laser overall in implementation process, without electric lighting system, can be divided into three parts: the Lights section, hop, illumination section.The Lights section comprises blue light LD1, coupling mirror 2, focus lamp 3; Hop comprises Transmission Fibers; Illumination section comprises reflector 5, focus lamp 6, fluorescent material plummer 7, plate glass 8.Electricity and illumination section are effectively thoroughly isolated by like this be designed with to be beneficial to.
In the illumination of dangerous material production, storage area, the Lights section is away from this region, transport light to illumination section excitated fluorescent powder by hop and form white-light illuminating, like this, be that illumination section drops, the reason such as to break and all can not produce electric spark, stopped the explosion issues that inflammable and explosive region causes due to lighting problem thoroughly.
