The specific embodiment
Those skilled in the art below cooperate Figure of description that embodiment of the present utility model is done more detailed description, so that can implement after studying this specification carefully according to this.
As shown in Figure 1, 2, the light supply apparatus that the utility model provides, it is a kind of lighting apparatus as light source that is applied to adopt such as LED, the body of described lighting apparatus includes the pedestal 4 that an appearance possesses a plurality of radiating fins, the front end of pedestal 4 is provided with a light source base 3, and 3 of light source bases are embedded a plurality of point source of lights 2; At embodiment of the present utility model, described point source of light 2 is LED; The outside of each light source 2 then is covered with lens 1 as media set.The inside of pedestal 4 also is provided with and is used for the circuit board and the driver (not shown) of driving light source, in pedestal 4 rear ends one bulb socket 5 is set again, and a lamp holder 6 is installed at last again; When lamp holder 6 is connected in lamp socket and switches on, get so that light source 2 is luminous, light casts out from lens 1 again.
As shown in Figure 3, the utility model is for a wherein preferred embodiment of described lens 1, for forming the cylindrical body of hollow, the inner surface of this cylindrical body is an incidence surface 11, the outer surface of this cylindrical body is an exiting surface 12, in addition, this incidence surface 11 is with exiting surface 12 can be with the cambered surface of light diffusion, this cambered surface can be parabola, sphere, aspheric surface ... etc. form; Moreover in order to obtain further anaclasis and reflection and improve the effect of brightness, described incidence surface 11 and/or exiting surface 12 can be provided with optical texture; This optical texture can adopt technology such as sandblast atomizing, etching, machinery or radium-shine processing to mold a plurality of thin prominent points or thin concave point at incidence surface and exiting surface.After described lens 1 are placed in outside the light source 2, when light source 2 is luminous, light is able to enter lens from incidence surface 11, penetrate from exiting surface 12 again, more soft after by lens 1 light being disperseed, spreads, thereby concentrate when being provided with at most light sources, can avoid producing repeatedly bad visual impacts such as shadow or rail shadow.
Again as shown in Figure 4, be the utility model another embodiment for described lens 1, described lens 1 form column, and an end of this column is an incidence surface 11, and the ring perimeter surface of column is an exiting surface 12; Same, described incidence surface 11 is with exiting surface 12 can be with the cambered surface of light diffusion, this cambered surface can be parabola, sphere, aspheric surface ... etc. form; Identical with aforementioned person, in order to obtain further anaclasis and reflection and improve the effect of brightness, described incidence surface 11 and/or exiting surface 12 can be provided with aforesaid optical texture.The lens 1 of described column can be inserted in the lampshade 13, again with lens 1 outside lampshade 13 is sheathed on light source 2.When light source 2 was luminous, light was able to enter lens from the incidence surface 11 of the lens 1 of column, penetrated from exiting surface 12 again, passed lampshade 13 then, similarly can be softer by lens 1 be disperseed light, spread afterwards.Moreover in order to obtain more near the effect of natural daylight, an amount of fluorescent material also can be added during fabrication in described lampshade 13 inside, and this fluorescent material can be according to will obtain photochromic and the selection color.
Other is the person, the three primary colors of light are ruddiness, green glow and blue light, present white light LEDs, the color of its light is too dazzling, and color rendering is poor, therefore, in order to obtain more natural light, the utility model also can be when making lens, according to the fluorescent material 14 (as shown in Figure 5) of actual needs portion's interpolation within it appropriate color, the light that light source projects is come out is able to mix to form increase with fluorescent material the mixed light of color rendering, makes it more level off to white light.For example, when described light source 2 is blue light, can add yellow, green or red fluorescence material in this lens 1, can make the mixed light that penetrates from this exiting surface more near white light or natural daylight; Certainly, also can adjust the proper proportion of this fluorescent material according to consumer demand, to produce various different colours light.
Fig. 6 is for showing that the utility model can wherein, can form the incidence surface 11 of one first lens 1A the plane by the embodiment of two lens as the media set matched combined, and exiting surface 12 forms cambered surface; The second lens 1B then has the incidence surface 11 and exiting surface 12 that is the plane, the incidence surface 11 that makes the exiting surface 12 of the second lens 1B and the first lens 1A near to or in contact with, light source 2 is injected light from the incidence surface 11 of the second lens 1B, exiting surface 12 from the first lens 1A penetrates at last, also can reach the change effect of shadow or rail shadow of identical elimination.Also can add the fluorescent material of predetermined color in the described second lens 1B according to need, to produce the mixed light of expection.
Fig. 7 is for showing that the utility model by two lens another embodiment as the media set matched combined, wherein, can form the incidence surface 11 of one first lens 1A cambered surface, and exiting surface 12 forms the plane; The second lens 1B then has the incidence surface 11 and exiting surface 12 that is the plane, the exiting surface 12 that makes the incidence surface 11 of the second lens 1B and the first lens 1A near to or in contact with, light source 2 is injected light from the incidence surface 11 of the first lens 1A, exiting surface 12 from the second lens 1B penetrates at last, can reach the change effect of shadow or rail shadow of identical elimination with Specifications.Also can add the fluorescent material of predetermined color in the described second lens 1B according to need, to produce the mixed light of expection.
The above only is in order to explain preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model according to this; therefore; all have in that identical creation spirit is following do relevant any modification of the present utility model or change, all must be included in the category of the utility model intention protection.
