Abstract
The utility model discloses a light-emitting diode (LED) spotlight. The LED spotlight comprises a light shell, a reflection bowl arranged inside the light shell, an LED light source module and a convex lens. The LED light source module is arranged inside the reflection bowl, and the convex lens is arranged in the front of the LED light source module. By means of the combination design of the LED light source module, the reflection bowl and the convex lens, light rays emitted from the LED light source module can be reflected by the reflection bowl and then converged by the convex lens, and therefore condensation effect of the LED spotlight is improved and also the purpose of improving lamination intensity is improved. By means of the design of a heat-dissipation device and a heat-dissipation block, heat-dissipation effect of the LED spotlight is improved and service life of the LED spotlight is prolonged. By means of the design of an adjusting screw rod, the distance between the LED light source module and the convex lens can be adjusted conveniently, and therefore the size of light spots can be adjusted and the LED light source module is wide in application range.

The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of LED spotlight, through adopting the combination design of led light source assembly, reflector and convex lens, can significantly improve its spotlight effect, and reach the purpose that improves illumination intensity.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The LED spotlight comprises lamp housing, is positioned at reflector, led light source assembly and the convex lens of lamp housing; Said led light source assembly is positioned at reflector, and said convex lens are positioned at the place ahead of led light source assembly.
Internal diameter from its rear end to this reflector of front end constantly increases; Said led light source assembly is positioned at the rear end of reflector.
This LED spotlight also comprises heat abstractor, and this heat abstractor comprises heat dissipation base, is connected to groups of fins on the heat dissipation base, is positioned at the blower fan of groups of fins top through heat pipe, and said led light source assembly is fixed on the heat dissipation base.
Also be arranged with several on the inner roof wall of said lamp housing towards the radiating block that extends below, its length direction of said radiating block upper edge is arranged with a plurality of radiating grooves that are inversion " V " shape.
Said radiating block lays respectively at the top of blower fan and reflector.
Said convex lens are installed on the travelling carriage; Also be provided with an adjusting screw mandrel along its length direction extension on this lamp housing, this adjusting screw mandrel is threaded with travelling carriage; The end of said adjusting screw mandrel passes from lamp housing, and is provided with handle.
The LED spotlight that the utility model is set forth, its beneficial effect is:
1, through adopting the combination design of led light source assembly, reflector and convex lens, the light that the led light source assembly is sent reflects through reflector, and the planoconvex lens converging ray, thereby improves its spotlight effect, and reaches the purpose that improves illumination intensity;
2, through adopting the design of heat abstractor and radiating block, can improve its radiating effect, prolong the service life of light fixture;
3, through adopting the design of regulating screw mandrel, can be convenient to regulate led light source assembly and convex lens distance, thereby regulate the size of hot spot, the scope of application is wider.
Description of drawings
Fig. 1 is the structural representation of the utility model LED spotlight;
Wherein, 1, lamp housing; 11, protecgulum; 12, bonnet; 13, chassis; 14, flat glass; 2, led light source assembly; 3, reflector; 4, convex lens; 51, heat pipe; 52, groups of fins; 53, blower fan; 6, regulate screw mandrel; 7, radiating block.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model LED spotlight done further describing, so that clearerly understand the utility model technical thought required for protection.
As shown in Figure 1, be the structural representation of the utility model LED spotlight, comprise lamp housing 1.The two ends of said lamp housing 1 are respectively equipped with protecgulum 11 and bonnet 12.Said protecgulum 11 and bonnet 12 dismountable being connected on the lamp housing 1.Through adopting above-mentioned design, can be convenient to change the part in the lamp housing 1.Be provided with flat glass 14 in the lamp housing 1, this flat glass 14 is positioned at the rear of protecgulum 11.
Also be provided with led light source assembly 2, reflector 3 and convex lens 4 in the lamp housing 1.Said led light source assembly 2 is positioned at reflector 3, and said convex lens 4 are positioned at the place ahead of led light source assembly 2.Concrete, the internal diameter from its rear end to front end reflector 3 constantly increases.Said led light source assembly 2 is positioned at the rear end of reflector 3.During use, the light that led light source assembly 2 sends is through reflector 3 reflections, and planoconvex lens 4 converging rays, can significantly improve its spotlight effect, and reaches the purpose that improves illumination intensity.
This LED spotlight also comprises heat abstractor, and this heat abstractor comprises heat dissipation base, connects groups of fins 52 on the heat dissipation bases, is positioned at the blower fan 53 of groups of fins 52 tops through heat pipe 51, and said led light source assembly 2 is fixed on the heat dissipation base.During use, the heat of led light source assembly 2 is passed on the groups of fins 52 through heat pipe 51, and utilizes blower fan 53 to quicken flowing of air, can the heat of groups of fins 52 be drained rapidly, thus the service life of prolongation light fixture.
Preferably, also be provided with travelling carriage in the lamp housing 1, said convex lens 4 are installed on the travelling carriage.Also be provided with an adjusting screw mandrel 6 along its length direction extension on this lamp housing 1.This adjusting screw mandrel 6 also is threaded with travelling carriage.Should regulate screw mandrel 6 for the ease of rotating, the end that the inventor also will regulate screw mandrel 6 passes from lamp housing 1, and is provided with handle endways.Through turning handle, can gyration that regulate screw mandrel 6 be converted into the rectilinear motion of travelling carriage, do rectilinear motion thereby drive convex lens 4, and then the distance of adjustment led light source assembly 2 and convex lens 4.When the close together of led light source assembly 2 and convex lens 4, beam angle is bigger, and the hot spot that light fixture penetrates is bigger, and be astigmatic; When the distance of led light source assembly 2 and convex lens 4 was far away, beam angle was less, and the hot spot that light fixture penetrates is less, and is optically focused.Because the size of this LED spotlight scalable hot spot, the scope of application is wider.
The bottom of lamp housing 1 also is provided with chassis 13.Also be arranged with several on the inner roof wall of said lamp housing 1 towards the radiating block 7 that extends below, its length direction of said radiating block 7 upper edges is arranged with a plurality of radiating grooves that are inversion " V " shape.Said radiating block 7 lays respectively at the top of blower fan 53 and reflector 3.Through adopting above-mentioned design, the circulation of heat can be convenient to, but also the effect of shading can be played, prevent the situation of light leak.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
