Fig. 2 is the assembling stereogram of the LED spotlight of the variable light beam angle of Fig. 1.
Fig. 3 is the profile of the LED spotlight of the variable light beam angle of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
Refer to 1 to Fig. 3, the present invention relates to a kind of LED spotlight of variable light beam angle, its better embodiment comprises lens 20, is laid with the light source board 10 of LED light source 30, radiator 40, light source driving circuit plate 50 and lamp socket 60.
Radiator 40 is installed on lamp socket 60, light source driving circuit plate 50 is installed in lamp socket 60, and light source board 10 is installed in radiator 40, and lens 20 can be installed on the upper end of this radiator 40 up or down, to regulate the vertical range between lens 20 and light source board 10, and then regulate the beam angle of shot-light.
Lens of the present invention can move up and down by opposite heat sink 40, by the lighting angle regulating the vertical range between lens 20 and light source board 10 to regulate shot-light, so, producer only needs a kind of lens die for subsequent use, namely by regulating the height of lens to meet the different beam angle demand of client, not only reduce production cost, also improve production efficiency.
In the present embodiment, the sidewall of lens 20 extends snap fit 21 downwards, spirality draw-in groove 41 is offered in the sidewall of radiator 40, the snap fit 21 of lens 20 is installed in the spirality draw-in groove 41 of radiator 40, so, snap fit 21 can be made to be installed in the differing heights position of spirality draw-in groove 41 by relay lens 20, thus realize moving up and down of lens 20 opposite heat sink 40.
Preferably, this spirality draw-in groove 41 comprises the circular arc recess of some coaxial lines and some guide ramp, and some circular arc recesses are spaced apart vertically, and the end of every two adjacent circular arc recesses is connected by a guide ramp; So, snap fit is made to be slided into the circular arc recess being in different height by guide ramp by relay lens 20.
In other embodiments, be provided with screw thread outside the sidewall of these lens 20, in the sidewall of radiator 40, correspondence is provided with the screw thread of coupling, and lens 20 can be installed on radiator 40 up or down by screw thread.So, realize lens opposite heat sink 40 by relay lens 20 to move up and down.
Preferably, the upper limb of lens 20 radially extends positioning protrusion 22, some domatic grooves 42 along the circumferential direction spaced apart are offered in the upper limb of radiator 40, the positioning convex 22 of lens 20 is installed in a wherein domatic groove 42 of radiator 40, so, make positioning convex 22 be installed in a wherein domatic groove 42 of radiator 40 by relay lens 20, be fixed in the lens 20 during the differing heights of radiator 40 further.
Preferably, corresponding each domatic groove 42 mark of outer surface of radiator 40 has corresponding beam angle label, so, when regulating beam angle, only need relay lens, make positioning convex 22 be installed in corresponding domatic groove 42, beam angle can be completed quickly and easily and regulate.
