Description

LED spotlight

Technical field

The utility model relates to field of LED illumination, particularly a kind of LED spotlight.

Background technology

LED illumination lamp have power consumption less, pollution-free, containing tribute, without screen dodge, easy to control, can the advantage such as light modulation, long service life, extensively promoted the use of because its advantage is many.

In current optical design, LED point light source by lens, reflector or both combine, it is possible to meet certain Small angle bright dipping requirement, it is achieved the light distribution characteristic needed for needing, rising angle, light spot shape and illumination requirement etc. And COB light source is due to the encapsulation characteristic of integrated optical source COB, surface source luminescence, size is bigger, when carrying out optical design, can not ignore with lens or the reflection of reflector or the distance of refracting interface, it is difficult to as pointolite rough handling, so being difficult to accomplish very little lighting angle. At present, in application in LED class shot-light, support the use major part to need lens are installed before COB light source, usually arranging lens in LED point light source respectively, lens rise and amplify light or concentrated effect of light, and existing lens the most conventional on the market are tapered lens, convex lens etc., though it can realize the effect concentrating light, but need to use material many, cause lens integral thickness thicker, thus take space many.

Practical novel content

The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of structure is simple, the LED spotlight that can realize Small angle luminescence.

The purpose of this utility model is achieved through the following technical solutions: a kind of LED spotlight, comprise lamp holder, Lamp cup, LED/light source plate and diffuser, this LED/light source plate is arranged in this Lamp cup, this LED/light source plate is provided with LED/light source, this diffuser covers at open top place of this Lamp cup, this diffuser comprises the exiting surface of incidence surface and the end face being positioned at bottom surface, this incidence surface is towards the globoidal structure protruded away from described LED/light source, this incidence surface is provided with multiple concentric ring slot around the axis of this diffuser, described ring slot comprises vertical plane and scarp, this scarp be used for by light towards be parallel to described LED/light source axis direction refraction.

Preferably, the angle of this vertical plane and this scarp composition outwards successively decreases by the axis of this diffuser.

Preferably, the angle of this vertical plane and this scarp composition is acute angle.

Preferably, this exiting surface is the globoidal structure away from the outwardly setting of described LED/light source.

Preferably, the middle part of this incidence surface is provided with middle part incidence surface, and in the middle part of this, incidence surface is protrude, towards described LED/light source, the globoidal structure arranged, and in the middle part of this, incidence surface and this exiting surface form convex lens structures.

Preferably, this LED/light source plate is two dimensional structure, and described LED/light source is formed centrally ring structure in this LED/light source plate.

Preferably, the inner side-wall of this Lamp cup is provided with flange, this LED/light source plate be arranged on this flange and with this Lamp cup hot tie-in.

The utility model has the following advantages:

1, by arranging ring slot on this diffuser, the light that LED/light source sends by ring slot towards be parallel to these LED/light source axis direction refraction, and on the exiting surface of this diffuser, there is two refractions, form the light of collimation, the axis parallel of the light that these LED/light source send and this diffuser or in a less angle, so, it is achieved that the light-out effect of Small angle, Small angle bright dipping just can be realized so that whole lamp structure is more simple by this diffuser.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

Embodiment one:

Please refer to Fig. 1, LED spotlight described in the utility model, comprises lamp holder 40, Lamp cup 30, LED/light source plate 20 and diffuser 10, and this LED/light source plate 20 is arranged in this Lamp cup 30, being provided with LED/light source 21 on this LED/light source plate 20, this diffuser 10 covers at open top place of this Lamp cup 30.

Please refer to Fig. 1, in the present embodiment, this LED/light source plate 20 is two dimensional structure, and these LED/light source 21 are formed centrally ring structure in this LED/light source plate 20. The inner side-wall of this Lamp cup 30 is provided with flange 31, this LED/light source plate 20 be arranged on this flange 31 and with this Lamp cup 30 hot tie-in.

Please refer to Fig. 2, this diffuser 10 comprises the exiting surface 12 of the incidence surface 11 and end face being positioned at bottom surface, this incidence surface 11 is towards the globoidal structure protruded away from these LED/light source 21, and this incidence surface 11 is provided with multiple concentric ring slot 112 around the axis of this diffuser 10. These ring slots 112 comprise vertical plane 1121 and scarp 1122, this scarp 1122 for by light towards be parallel to these LED/light source 21 axis direction refraction. This vertical plane 1121 is acute angle with the angle of this scarp 1122 composition. This vertical plane 1121 outwards successively decreases by the center of this diffuser 10 with the angle of this scarp 1122 composition. Preferably, the angle that this vertical plane 1121 and this scarp 1122 form outwards successively decreases by the center of this diffuser 10 and forms arithmetic progression. In addition, the middle part of this incidence surface 11 is provided with middle part incidence surface 113, in the middle part of this, incidence surface 113 is protrude, towards these LED/light source 21, the globoidal structure arranged, and in the middle part of this, incidence surface 113 and this exiting surface 12 form convex lens structures, to be reflected towards near the axis of this diffuser 10 by light. In addition, this exiting surface 12 is the globoidal structure away from these outwardly settings of LED/light source 21, light after the vertical plane 1121 and scarp 1122 refraction of this incidence surface 11 enters this exiting surface 12, and due to this exiting surface 12 be protrude globoidal structure, therefore, light occurs to reflect for two times on this exiting surface 12, form the light of collimation, the axis parallel of the light that these LED/light source 21 send and this diffuser 10 or in a less angle, so, it is achieved that the light-out effect of Small angle.The structure of lens multiple compared to existing employing, the utility model just can realize Small angle bright dipping by this diffuser 10, and structure is more simple.

The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacements, improvement etc., all should be included within the scope that the utility model is protected.
