Description
Technical field
The present invention relates to a kind of LED light fixture, refer to a kind of design that utilizes two groups of led light sources and two asymmetric reflecting parts especially, the LED light fixture with illumination range that two kinds of different beam angles are provided is applicable to the use of car light, projecting lamp etc.
Background technology
Along with science and technology is maked rapid progress, illuminating light source is replaced with light-emittingdiode (LED) gradually, yet because LED has high brightness, power saving, volume is little and advantage such as environmental protection, therefore such as in personal digital product, means of transportation, car light or architectural lighting, all adopt the design of LED as light source.
At present LED use with research and development on all towards the lifting of brightness, increase its high efficiency irradiation purpose, the illumination of one scope angle only is provided provide at a light fixture in its design, with the car light is example, tradition uses LED as the car light high beam of light source and the light source design of dipped headlights, because the faces that the characteristic of LED is a genus 180 to be spent are luminous, and its practice is that LED is directly throwed the place ahead, and the light of wide-angle is received light with reflecting part (cup), to form the illumination range of a fixed angle.Yet, the shortcoming of described design is that high beam and dipped headlights can't use same lampshade, that is to say just can provide two different illumination ranges by two lampshade modules, same problem is used on the LED light fixture in field at other, also must just can provide two different illumination ranges, make and in the configuration in overall structure space, must be considered by two lampshade modules.
Summary of the invention
Main purpose of the present invention is to provide a kind of LED light fixture that the illumination range of two kinds of different beam angles is provided.
For reaching above-mentioned purpose, a kind of LED light fixture that the present invention is set, comprise a lamp housing and a lighting device, wherein said lamp housing has an accommodation space, described lamp housing inside is to be provided with two asymmetrical, second reflecting parts, and described first, second reflecting part is the reflecting surface that is respectively equipped with a specific curvature; Described lighting device is arranged in the accommodation space, described lighting device comprises first led light source and second led light source that can distinguish independent illumination, wherein said first, second led light source is respectively towards the reflecting surface of first, second reflecting part, so that the light that described first, second led light source throws respectively, can reflect by its corresponding reflecting surface, to form neither illumination range with the light beam angle.
Compared with prior art, the beneficial effect that the present invention has is: the present invention can be in a lamp housing, utilize the design of two set asymmetric reflecting parts of two groups of led light sources and lamp interior, and the LED light fixture of the illumination range of two kinds of different beam angles is provided, have simple in structure, cost is low, fit the advantage of using at car light, projecting lamp etc.

The specific embodiment
See also Fig. 1, Fig. 2, diagramatic content is an embodiment of LED light fixture 1 of the present invention, and it mainly comprises a lamp housing 2 and a lighting device 3.
Described lamp housing 2 has an accommodation space 21, described lamp housing 2 one end faces are to be combined with a lampshade 22, described lamp housing 2 inside are to be provided with two asymmetrical first, second reflecting parts 23,24, and described first, second reflecting part the 23, the 24th, are respectively equipped with the reflecting surface 231,241 of a specific curvature.
Described lighting device 3 is arranged in the above-mentioned accommodation space 21, described lighting device 3 comprises first led light source 31 and second led light source 32 that can distinguish independent illumination, wherein said first, second led light source the 31, the 32nd is respectively towards the reflecting surface 231,241 of first, second reflecting part 23,24, so that light described, that second led light source 31,32 throws respectively, can reflect by its corresponding reflecting surface 231,241, to form neither illumination range with the light beam angle.Again, described lighting device 3 comprises a heat abstractor 33 that is connected with second led light source 32 with described first led light source 31 in addition, and the supply unit 34 that first led light source 31 and the second led light source power supply 32 are provided respectively.
During enforcement, please consult Fig. 1～Fig. 4 again, the present invention during fabrication can be earlier according to user's demand, the intensity effect of the prior beam angle that reach, and design first, second reflecting part 23,24 required curvature, as to make the light of described first led light source 31 projection be the illumination range of light after reflecting surface 241 reflections of second reflecting part 24 that is distal to 32 projections of second led light source from the illumination range after reflecting surface 231 reflections of first reflecting part 23, and described first, second reflecting part 23,24 reflecting surface 231, the 241st, be one respectively and have the shiny surface of specific curvature or be a non-smooth burnishing surface (shown in Fig. 2 A) with asperities shape.
Therefore, when the present invention is applied in car light and during as high beam and dipped headlights, at first at lamp housing 2 inner two asymmetrical first, second reflecting part 23, on 24, according to distance light, the difference of the illumination range of dipped beam and first, second reflecting part 23,24 are provided with the reflecting surface 231 of a specific curvature, 241, the light that makes 31 projections of described first led light source is the illumination range b of light after reflecting surface 241 reflections of second reflecting part 24 that is distal to 32 projections of second led light source from the illumination range a after reflecting surface 231 reflections of first reflecting part 23, make the led light source 31 of winning form the light source (as shown in Figure 3) of high beam, second led light source 32 then can form the light source (as shown in Figure 4) of dipped headlights.
More than explanation is just illustrative for the purpose of the present invention, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present invention.
