Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 3, a kind of embodiment of light source of the present invention is described in detail.The light source of the present embodiment comprises LED1, interior cell-shell 2 and outside bulb shell 3.Described light source also comprises substrate 11, radiator 5 and lamp holder 6.Described LED1 is arranged on described substrate 11, and described substrate 11 is simultaneously for powering to described LED1.Described substrate 11 is arranged on the end face of wherein one end of described radiator 5, and such as, described substrate 11 can be fixed on this end face by screw lock.Described lamp holder 6 is connected with the other end of described radiator 5, and such as, both are threaded connection.Described interior cell-shell 2 is arranged in the cavity of described outside bulb shell 3, and described LED1 is arranged in the cavity of described interior cell-shell 2.The light of described LED1 is successively through described interior cell-shell 2 and outside bulb shell 3 outgoing, the cross-sectional area of described interior cell-shell 2 at least partial section reduces gradually along the optical axis direction of described LED1, and the cross-sectional area of described outside bulb shell 3 at least partial section increases gradually along the optical axis direction of described LED1.It should be noted that, be the optical axis direction of this LED1 with the directions of rays straight up that the mid point of the light-emitting area of a LEDs 1 any in Fig. 2 is starting point.Also it should be noted that, the area that the intersection perpendicular to the plane of the optical axis direction of described LED1 and the outer surface of described interior cell-shell 2 surrounds is the cross-sectional area of described interior cell-shell 2; The area surrounded perpendicular to the intersection of the plane of the optical axis direction of described LED1 and the outer surface of described outside bulb shell 3 is the cross-sectional area of described outside bulb shell 3.Described interior cell-shell 2 is made up of the material making light spread, such as acrylic or PC.Described outside bulb shell 3 is made up of the material making light spread, such as acrylic or PC.Reduce gradually along the optical axis direction of described LED1 by making the cross-sectional area of described interior cell-shell 2 at least partial section, this section of described interior cell-shell 2 is tilted to the inside, more light of described LED1 can be made to be irradiated to this section, and because described interior cell-shell 2 is made up of diffusion material, the angle of the some light of the LED1 through this section can be made to increase; Increase gradually along the optical axis direction of described LED1 by making the cross-sectional area of described outside bulb shell 3 at least partial section, this section of described outside bulb shell 3 is tilted laterally, make the outer surface of this section towards the wide-angle direction of described light source, and because described outside bulb shell 3 is made up of the material making light spread, thus the angle of the some light of the LED1 through this section is increased again, thus make more light be irradiated to wide-angle direction, increase the shooting angle of the light of described light source.In the present embodiment, described interior cell-shell 2 comprises sidewall 21 and the roof 22 be connected from the one end away from described LED1 with its sidewall 21, and the cross-sectional area of the sidewall 21 of described interior cell-shell 2 reduces gradually along described LED1 optical axis direction.It should be noted that, the area that the intersection perpendicular to the plane of the optical axis direction of described LED1 and the outer surface of described sidewall 21 surrounds is the cross-sectional area of described sidewall 21.Described outside bulb shell 3 comprises sidewall 31 and the roof 32 be connected from the one end away from described LED1 with its sidewall 31, and the cross-sectional area of the sidewall 31 of described outside bulb shell 3 increases gradually along described LED1 optical axis direction.It should be noted that, the area that the intersection perpendicular to the plane of the optical axis direction of described LED1 and the outer surface of described sidewall 31 surrounds is the cross-sectional area of described sidewall 31.Reduce gradually along the optical axis direction of described LED1 by making the cross-sectional area of the sidewall 21 of described interior cell-shell 2, described sidewall 21 is tilted to the inside, more light of described LED1 can be made to be irradiated to sidewall 21, and because described interior cell-shell 2 is made up of diffusion material, the angle of the some light of the LED1 through sidewall 21 can be made to increase;
