Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of LED light fixture of the light emitting region regulated simple in structure, easy to adjust is provided.
The technical solution adopted in the present invention is: the present invention includes lamp holder, the lamp body, the LED luminescence component of band heat-radiating substrate, lens, described lamp body and described lamp holder are fixedly connected, the LED luminescence component of described band heat-radiating substrate is fixed in described lamp body inside, described lens are positioned at bright dipping the place ahead of the LED luminescence component of described band heat-radiating substrate, the described LED light fixture of regulating light emitting region also comprises the anticreep spacing collar, fixing cover, regulate cover, being fixedly connected of described fixedly cover and described lamp body, described lens are fixed in described adjusting range and cover, the madial wall of described fixedly cover is provided with internal thread, the lateral wall of described adjusting cover is provided with external screw thread, described external screw thread is connected with described internal thread is suitable, the socket of described anticreep spacing collar and be fixed in described adjusting cover lateral wall the bottom and stop described adjusting cover to screw out to come off from described fixedly cover.
The embedded intrinsic radiating bottom plate of described lamp body, the LED luminescence component of described band heat-radiating substrate and described radiating bottom plate are fixedly connected and heat conduction.
The LED luminescence component of described band heat-radiating substrate has aluminium base, and described lamp body adopts the aluminium manufacturing, and described lamp is provided with some radiating fins on one's body.
Described adjusting range covers the manual adjustments portion that is provided with.
Described manual adjustments portion is salient point or groove.
Described adjusting range covers and is provided with token-based on schedule, and described stationary plane covers and is provided with the lighting angle mark, the described lighting angle mark indication lighting angle that described token-based is corresponding on schedule.
Described lamp holder is provided with the lamp pin, and described lamp pin is electrically connected by the LED luminescence component of lead and described band heat-radiating substrate.
Described fixedly cover and described lamp body are fixedly connected by the wedge pressure tight fit, and described lens are adhesively fixed and cover in described adjusting range.
The model of described lamp holder is GU10 or GU5.3 or MR16 or E14 or E26 or E27 or B22.
The invention has the beneficial effects as follows: owing to the present invention includes the anticreep spacing collar, fixing cover, regulate cover, being fixedly connected of described fixedly cover and described lamp body, described lens are fixed in described adjusting range and cover, the madial wall of described fixedly cover is provided with internal thread, the lateral wall of described adjusting cover is provided with external screw thread, described external screw thread is connected with described internal thread is suitable, the socket of described anticreep spacing collar and be fixed in described adjusting cover lateral wall the bottom and stop described adjusting cover to screw out to come off from described fixedly cover, the present invention by the socket of described anticreep spacing collar and be fixed in described adjusting cover lateral wall the bottom and stop described adjusting cover to screw out to come off from described fixedly cover, described adjusting cover and described lens are determined in axial moving range, described adjusting cover is when described fixedly cover and described lamp body rotate, by cooperating of described external screw thread and described internal thread, driving described adjusting cover and described lens moves vertically, thereby can regulate the distance between described lens and the LED, change the lighting angle of described LED through the light of described lens, not only can accurately control the angle of bright dipping, and make and also can change size thereupon regulating at the spot size that shines preset distance, in addition when regulating spot size, its illumination also changes thereupon, hot spot is more little, illumination is high more, hot spot is big more, illumination is low more, be that distance between lens of the present invention and the LED can be regulated as required, and it is easy to adjust, make light fixture when different occasions are used, can adjust hot spot and illumination size as required, so the present invention is simple in structure, easy to adjust, spot size can be regulated, and then can regulate light emitting region;
Because the LED luminescence component of band heat-radiating substrate of the present invention has aluminium base, described lamp body adopts the aluminium manufacturing, described lamp is provided with some radiating fins on one's body, the heat that produces when the LED luminescence component of described band heat-radiating substrate is luminous is transmitted to described lamp body and is dispersed in the air rapidly by described radiating fin by its aluminium base, so good heat dissipation effect of the present invention, long service life.
