Abstract

The utility model discloses an even LED shot -light of facula, including radiator, face ring, optical lens and LED light source board, this radiator has open -top's an inner chamber, LED light source board is fixed in this inner chamber bottom, the face ring cowling is at the radiator top and through helicitic texture and radiator fixed connection, optical lens seals in the inner chamber opening part and passes through the back -off has a plurality of equally spaced insections of working in unison with the face intra -annular along lock, the central department of this optical lens top surface, and the optical lens bottom has two concentric big, little bowls that leak hopper -shaped that just are. Optical lens is close to the installation with the flat line of LED light source for come from the light yield of LED light source board and can pass through optical lens's refraction at once and form the laser angle of needs, effectively assemble the light yield of LED light source board in the degree of depth of limited optics chamber.

Description

A kind of hot spot is uniform LED Shot-light

Technical field

This utility model relates to light fixture, especially a kind of uniform LED spotlight of hot spot.

Background technology

LED light source has that luminous body is little, caloric value is little, light efficiency advantages of higher, and these advantages make LED obtain the use of override developing in directional lighting particularly shot-light field.

In the shot-light of LED is applied, current substantial amounts of example is the form using and directly replacing conventional light source, such as LED PAR lamp, its overall dimensions, lamp holder, electric parameter and optical property etc. will substitute corresponding incandescent or halogen PAR lamp completely, in order to reach the requirement of luminous flux, LED light source often takes the form of array, rather than a luminous point.But this have the consequence that the light-emitting area of light source becomes big, the space that its optical texture needs just becomes big.Meanwhile, array LED also can increase the volume of whole lamp radiator, therefore, how to design relevant LED spotlight optics and radiator structure, make the LED light source with big exiting surface can be processed into the optical effect of optically focused, the most not because the volume increasing sacrifice radiator structure of optical space, it will be a vital problem.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of uniform LED spotlight of hot spot.

The technical solution adopted in the utility model is:

A kind of uniform LED spotlight of hot spot, including radiator, face ring, optical lens and LED light source plate, this radiator has open-topped inner chamber, described LED light source plate is fixed on this intracavity bottom, described ring cowling is connected at radiator top and by helicitic texture and radiator are fixing, and described optical lens is sealed at lumen openings and passes through back-off and radiator inner edge fastening；This optical lens end face center has some equidistant concentric grooves, has two with one heart and in funnelform large and small reflector bottom optical lens.

Described back-off has two and is shaped in the both sides of optical lens.

Described ring both sides respectively offer a draw-in groove, are provided with torsion spring in this draw-in groove.

The wiring hole of communication with cavity, louvre and the Line pressing buckle locked by screw it is provided with bottom described radiator.

The beneficial effects of the utility model:

1. optical lens and LED light source plate are parallel and near to installation so that the light from LED light source plate exports the beam angle that can form needs at once through the refraction of optical lens, exported by the light of LED light source plate and effectively converge in the limited optics cavity degree of depth.

2. optics cavity can be directly molded in radiator, and need not take additional space；And, optics cavity sidewall be cylinder side wall coordinate have bottom optical lens two with one heart and in funnelform large and small reflector, use high reflectance surface, increase order of reflection, light is softer, is further ensured that minimum space and the output light efficiency of whole optics cavity.

3. optical lens is anchored on radiator front end so that whole lamp exterior contour is compact without taking extra light fixture volume.

4. the outer surface of optical lens is some equidistant concentric grooves, makes the light beam after optical lens reflects be rearranged, more uniformly.

Detailed description of the invention

As Figure 1-5, for a kind of uniform LED spotlight of hot spot of the present utility model, including radiator 10, face ring 20, optical lens 30 and LED light source plate 40.

This radiator 10 has open-topped inner chamber 101, this inner chamber 101 is used for installing LED light source plate 40 and as heat dissipation cavity, face ring 20 covers at radiator 10 top and is connected by helicitic texture is fixing with radiator 10, concrete, this helicitic texture includes being positioned at 10 liang of lateral walls of radiator and the connection post 102 of band screw, and it being arranged on the first screw 201 of face ring 20 two side, this first screw 201 connects with the screw being connected post 102 and positions with the fixing and angle realizing between face ring 20 and radiator 10.

Such as Fig. 3, Fig. 4, described optical lens 30 is sealed in inner chamber 101 opening part, and the both sides of optical lens 30 have integrated two back-offs 301, and described back-off 301 fastens with the described draw-in groove with radiator 10 inner edge, thus fixed by optical lens 30.This optical lens 30 end face center has some equidistant concentric grooves 304, has two and use high reflectance surface, increase order of reflection with one heart and in funnelform big reflector 302, little reflector 303 bottom optical lens, and light is softer.

Additionally, face ring 20 both sides respectively offer a draw-in groove 202, in this draw-in groove 202, torsion spring 203 is installed, just can rely on the torsion of torsion spring 203 that shot-light is fixed on installation position by two torsion springs 203.

Such as Fig. 2; the wiring hole 104 of communication with cavity, louvre 105 and the Line pressing buckle 106 locked by screw it is provided with bottom described radiator 10; wiring hole 104 is used for wearing wire to connect external drive power supply and LED light source plate 40; louvre 105 is for the ventilation and heat of inner chamber, to protect light source life；And Line pressing buckle 106 is for pinning wire to prevent the faults such as loose contact or the open circuit pullled.

The foregoing is only preferred embodiments of the present utility model; this utility model is not limited to above-mentioned embodiment; such as; the shape of container can be diversified; it is not limited only to the spherical of diagram, as long as realizing within the technical scheme of this utility model purpose broadly falls into protection domain of the present utility model with essentially identical means.
