The reflector comprises a flat main body; a horn-shaped reflection hole corresponding to the LED light sources is arranged in the main body; and the LED light sources are positioned at the bottom of the reflection hole. Compared with the prior art, the LED spot lamp reflector has the following advantages that: firstly, the light loss is reduced; secondly, the LED spot lamp reflector is less affected by the environment and can not deteriorate and yellow; and thirdly, a light beam angle can be adjusted to increase the functional applications of the lamp.
Description
Technical field
The utility model relates to a kind of LED shot-light and improves structure.
Background technology
LED shot-light reflector (claiming " LED shot-light reflector " again) is vitals in the LED shot-light, and these parts play the effect of regulating led light source beam angle, luminous intensity distribution to light.
Present commercially available LED shot-light product mainly adopts the PC(Merlon) or the PMMA(acrylic) plastic lens, in lens, having the shrinkage pool that does not have perforation, led light source is arranged in shrinkage pool, and the refraction of led light source rays pass through lens is spread to the outside.In detail as shown in Figure 1.1), lens mostly are integrated design mainly there is following problem in this base part:, the moulding of pattern tool, integral body is transparent, be designed to convex lens or concave mirror realizes that difference requires luminous intensity distribution by minute surface, its lateral parts can't form reflection, causes the light direct losses, calculate apart from the angle that forms according to led light source and lens surface, its light loss reaches about 15%, and the light light loss is bigger, therefore directly causes whole lamp efficiency on the low side.2), influenced by working environment, under hot environment and ultraviolet irradiation, adopt the lens of this material to wear out gradually, rotten jaundice, its light transmission is further descended, the whole lamp result of use of final influence is subjected to.3), such lens pattern tool global formation, according to fixing beam angle design, whole lamp distribution curve flux all is that irradiating angle is fixed, and is non-adjustable, has certain limitation during use by corresponding lens decision.
The utility model content
In view of this, the technical problems to be solved in the utility model is to overcome existing reflector defective, provide that a kind of fiber-loss is little, the LED shot-light reflector of long service life.
Thus, the utility model adopts following scheme to realize:
A kind of LED shot-light reflector, be installed on LED shot-light lamp body inside, be positioned at light source board the place ahead that a plurality of led light sources are installed, this reflector comprises a flat body, is provided with the horn-like reflection hole corresponding with led light source in body, and led light source is positioned at the reflection hole bottom.
As improvement, the reflector layer of reflection led light source light is arranged at the reflection hole plating inner surface to such scheme.
As further improvement of these options, between described body and the lamp body flexible connection that can move axially, be used to regulate led light source light reflection angle along lamp body.
And, being respectively arranged with the projection and the groove that can cooperatively interact at reflector bodies sidewall and lamp body inwall, projection axially is provided with along lamp body with groove.
Relative prior art the utlity model has following advantage:
1, reduce light loss:
Because reflector is an independent design, led light source light is by reflecting to external exposure, luminous intensity distribution has directly utilized reflection hole angle and light source and launch hole focal length centre distance to form and has finished, all light all can evenly be reflected, it is minimum that light loss is reduced to, directly promote the luminous efficiency of light fixture, and increase luminous intensity.
2, affected by environment little, jaundice undergoes no deterioration:
This reflector reflector layer can adopt the metal electroplating technology to make, reflector layer has the metal material characteristic, the advantage that can possess aspects such as high temperature resistant, ultra-violet radiation resisting, and because the reflecting layer is minute surface (nontransparent) design, therefore lamp luminescence efficient can be because of material ageing be subjected to direct influence, thereby effectively prolongs light fixture service life.
3, can realize the beam angle adjusting, increase the light fixture functional application:
Because reflector focal length and led light source distance are adjustable, when reflector reflection hole angle is constant, by regulating this apart from adjustable light distribution, have increased light fixture beam angle fine adjustment function, the user is the selectivity luminous intensity distribution as required.
Description of drawings

Fig. 2 is the utility model embodiment overall structure schematic diagram;
Fig. 3 is a present embodiment decomposing state structural representation.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
Shown in accompanying drawing 2～3, the LED shot-light reflector that this programme discloses is used at existing LED shot-light fiber-loss greatly, easily aging and beam angle defective such as can not regulate and a kind of improvement project of proposing.
The LED shot-light that this scheme relates to comprises lamp socket 4 and is installed on lamp body 1, face frame 5 on the lamp socket 4 successively, in lamp body 1 bottom light source board 2 is installed, and a plurality of led light sources 21 are installed on the light source board 2.Reflector bodies 3 and one is installed between light source board 21 the place aheads and face frame 5 successively expands tabula rasa 6.Wherein, this reflector bodies 3 is a flat, is provided with the corresponding horn-like reflection hole 31 of a plurality of and led light source 21 in body 3, and led light source 21 is positioned at reflection hole 31 bottoms, and specifically led light source 21 is positioned on reflection hole 31 axis.
In order to guarantee led light source 21 light reflecting effects, the reflector layer 4 of reflection led light source 21 light is arranged at reflection hole 31 plating inner surfaces.The metal material layer that forms is electroplated for adopting metal to electroplate minute surface technology in this reflecting layer 4, the surface smoothness height, to the light reflectance height, and these reflector layer 4 high temperature resistant, ultra-violet radiation resistings, can aging yellowing and influence reflecting effect, also can effectively prolong light fixture service life.
Simultaneously, regulating the angle of reflection of each led light source 21 light in reflection hole 31 for convenience, is can be along lamp body 1 axially movable flexible connection between reflector bodies 3 that present embodiment adopts and the lamp body 1.Promptly be respectively arranged with the projection 32 and the groove 11 that can cooperatively interact at reflector bodies 3 sidewalls and lamp body 1 inwall, projection 32 axially is provided with along lamp body 1 with groove 11.By adjusting body 3 positions, can regulate the distance between led light source 21 and reflection hole 31 focal lengths, thereby regulate the diffusion angle after the reflection of led light source 21 light, reach optimal illuminating effect, be user-friendly to.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be noted that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model design; can also make some distortion and improvement; concrete related light fixture can be MR16 type in the shot-light series, GU10 type, AR111 type, PAR20 type, PAR30 type, PAR38 type shot-light and rail shot-light, suction top shot-light, Projecting Lamp, fixed light fixture or ceiling type light fixture etc.; do not limit at this, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
