Description

A kind of LED-based combined light source

Technical field

The utility model is specifically related to a kind of LED Down lamp.

Background technology

LED progressively substitutes conventional light source incandescent lamp, electricity-saving lamp etc. as one energy-saving and environmental protection of new generation, miniature light sources, becomes the selection of current the best; In current LED Down lamp, due to the control to light and use not rigorous, cause glare phenomenon, display effect is bad, easily causes visual fatigue, even can affect user's eyesight.

So problem demanding prompt solution is that a kind of LED Down lamp that has better display effect and can effectively avoid glare phenomenon to occur is provided.

Utility model content

The utility model provides a kind of New LED combined light source for solving prior art problem.

The technical solution of the utility model is as follows: a kind of LED-based combined light source, comprises lighting device, diffuser and reflector; Described lighting device comprises lamp holder and LED light source; Described LED light source is arranged at lamp holder bottom, and around being arranged on lamp holder inner side; Described diffuser is connected with lamp holder bottom is adaptive; Described reflector one end opening, the other end is offered a through hole; Described diffuser stretches in reflector through described through hole, and described lamp holder bottom is connected with the through hole adaptation of reflector.

Preferred version, described lamp holder arranged outside has draw-in groove; Described draw-in groove is that multiple draw-in grooves are connected around being arranged at lamp holder outside; Described reflector top is provided with the buckle suitable with described draw-in groove; Described draw-in groove and buckle engagement connection.

Preferred version, multiple heat radiation through holes are offered in described lamp holder outside; Described heat radiation through hole is around being arranged at lamp holder sidewall.

Preferred version, described lighting device also comprises power module, described LED light source is electrically connected with power module.

Preferred version, described diffuser is hemisphere.

Preferred version, described diffuser is connected with cap screw thread.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

As shown in Figure 1, Figure 2, shown in figure tri-, the LED-based combined light source of one of the present utility model, comprises lighting device 1, diffuser 2 and reflector 3; Described lighting device comprises lamp holder 101 and LED light source; Described LED light source is arranged at lamp holder 101 bottoms, and around being arranged on lamp holder 101 inner sides; Described diffuser 2 is connected with lamp holder 101 bottoms are adaptive; Described reflector 3 one end openings, the other end is offered a through hole 4; Described diffuser 2 stretches in reflector 3 through described through hole 4, and described lamp holder 101 bottoms are connected with through hole 4 adaptations of reflector 3.

Preferred version, described lamp holder 101 arranged outside have draw-in groove 102; Described draw-in groove 102 is connected around being arranged at lamp holder 101 outsides for multiple draw-in grooves; Described reflector 3 tops are provided with the buckle 301 suitable with described draw-in groove 102; Described draw-in groove 102 and buckle 301 engagement connections.

Preferred version, multiple heat radiation through holes are offered in described lamp holder 101 outsides; Described heat radiation through hole is around being arranged at lamp holder 101 sidewalls, is conducive to LED light source heat radiation, avoids answering LED light source to use for a long time heating and the circuit that causes damages problem.

Preferred version, described lighting device 1 also comprises power module, described LED light source is electrically connected with power module.

Preferred version, described diffuser 2 is hemisphere; According to anaclasis principle, the light that LED light source sends sees through diffuser 2 and weakens intensity of illumination and change radiation direction, it is more even that the light that sees through diffuser 2 scatters light through curved surface refraction, thereby avoid that common LED Down lamp illumination light and shade is strong, the phenomenon of skewness.

Preferred version, described diffuser 2 is threaded with lamp holder 101; Preferred version, diffuser 2 and lamp holder 101 can engagement connections; Preferred version, diffuser 2 can be spirally connected with lamp holder 101.

Preferred version, described reflector 3 is set to round table-like.

When use, LED light source is connected to power module, lighting device 1 can use as lighting apparatus separately, diffuser 2 is hemisphere, due to anaclasis principle, can expand LED light source illumination zone, if desired dwindle illumination zone, lighting device 1 can be combined with reflector 3, can effectively eliminate glare phenomenon.The diffuser 2 of lamp holder 101 bottoms is stretched in reflector 3, be positioned at the buckle 301 in lamp holder 101 outsides and be connected completely with the draw-in groove 102 in glow cup, can be used in combination.

It should be noted that, above-mentioned each technical characterictic continues combination mutually, forms the various embodiment that do not enumerate in the above, is all considered as the scope that description of the present invention is recorded; And, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
