Wherein, the common luminous intensity distribution of described reflector and light-guiding pillar, the light intensity half-angle of shot-light is 20 degree.
Wherein, described light-guiding pillar in the face of the geometry of one end of light source upright projection on reflector bottom identical with light source, and projected area is not less than the area of light source.
Wherein, described light source is circular, and its diameter is 10 millimeters, and described light-guiding pillar is 5 millimeters-6 millimeters corresponding to one end of light source to the distance of light source.
Wherein, also comprise lamp housing and front end ring cowling, described reflector is arranged in lamp housing, and described transmissive mirror hides in the rim of a cup of reflector and by described front end ring cowling and presses solidly in lamp housing.
Wherein, described light source is COB light source.
The beneficial effects of the utility model are: the shot-light that is different from prior art, only have reflector to receive light, the light of light source center has part light and by reflector, does not draw in, but penetrate to surrounding from the rim of a cup of reflector, make light intensity lower, shot-light of the present utility model, a light-guiding pillar is set in transmissive mirror corresponding to light source, the light that utilizes light-guiding pillar not drawn in by reflector, by this light-guiding pillar, drawn in, can receive fully light like this, improve light intensity, and light-guiding pillar and light source have the spacing can be so that the light effect that COB shot-light of the present utility model penetrates is better, brightness is moderate.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of the COB shot-light of the utility model one embodiment;
Fig. 2 is the cross section structure schematic diagram of the COB shot-light of the utility model one embodiment.
In figure: 1, COB light source; 2, reflector; 3, transmissive mirror; 31, light-guiding pillar; 32, groove; 33, lens pearl; 4, lamp housing; 5, front end ring cowling.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 and Fig. 2, a kind of COB shot-light of present embodiment, it comprises COB light source 1, reflector 2 and transmissive mirror 3; Described COB light source 1 is arranged at the cup end of reflector 2, and described transmissive mirror 3 hides in the rim of a cup of reflector 2; Described transmissive mirror 3 is formed with light-guiding pillar 31 towards COB light source 1 and corresponding to COB light source 1, and light-guiding pillar 31 has spacing with COB light source 1.COB shot-light of the present utility model, a light-guiding pillar 31 is set in the transmissive mirror 3 of COB light source 1 correspondence, the light that utilizes light-guiding pillar 31 not drawn in by reflector 2, by this light-guiding pillar 31, drawn in, can receive fully light like this, improve the light intensity of COB shot-light front end, and light-guiding pillar 31 and COB light source 1 have the spacing can be so that the light effect that COB shot-light of the present utility model penetrates is better, brightness is moderate.
Light-guiding pillar 31 described in the present embodiment can be columniform, can be also prismatic, can also be round platform, so long as it is just passable to play receipts light action.In the present embodiment, the formation of light-guiding pillar can be one-body molded with transmissive mirror, and production transmissive mirror so fast can be assembled shot-light of the present utility model fast.
In the present embodiment, the end face of described light-guiding pillar backlight is frosting, namely transmissive mirror 3 dorsad the one side of COB light source 1 corresponding to the position of described light-guiding pillar 31, be frosting, can make like this light more even, play certain anti-dazzle effect.
In the present embodiment, described light-guiding pillar 31 dorsad the end face of COB light source 1 lower than the upper surface of described transmissive mirror 3, be in described transmissive mirror 3, to be formed with the position of light-guiding pillar 31 to COB light source 1 one side depressions, form a groove 32, such design can be saved the material of transmissive mirror in the situation that not affecting receipts light, can also imitate traditional Halogen lamp LED, make its structure attractive in appearance.Further, described light-guiding pillar 31 is provided with protruding lens pearl 33 on the end face of COB light source dorsad, it is the recess of described transmissive mirror 3, the bottom that is groove 32 is provided with protruding lens pearl 33, hemispherical lens pearl 33 can further be received light, make through the light of lens pearl 33 more concentrated, can beautify global design of the present utility model simultaneously, certainly, for anti-dazzle, on the bottom of hemispherical lens pearl 33 and groove 32, be all arranged to frosting, in this enforcement, described lens pearl 33 is hemispheric, to greatest extent optically focused.
