The specific embodiment
Fig. 1 is the generalized section according to the LED source of the utility model one preferred embodiment.Please refer to Fig. 1, LED source 120 of the present utility model comprises a reflector 100 and a plurality of light emitting diode 110.Reflector 100 has an outer surface 102, an inner surface 104 and a light and penetrates opening 106.The material of reflector 100 can be known any material with reflectivity properties, for example is metal.At this, reflector 100 has the profile of curved surface, and the place ahead of reflector 100 is the opening of curved surface, and it promptly is the light ejaculation opening 106 of reflector 100, and the rear of reflector 100 then is the turning of curved surface.
In a preferred embodiment, comprise also on the inner surface 104 of reflector 100 being coated with a reflectance coating 108 that it can promote the reflection efficiency of the inner surface 104 of reflector 100.And the material of reflectance coating 108 for example is minute surface coating material (mirror coating material).
In addition, light emitting diode 110 is to be disposed on the inner surface 104 of reflector 100, and the inner surface 104 that the light launched of light emitting diode 110 114 can directive reflectors 100, again from inner surface 104 reflections and the light of directive reflector 100 penetrates opening 106.At this, light emitting diode 110 can be disposed at any position of the inner surface 104 of reflector 100, so long as can make the inner surface 104 that light 114 that light emitting diode 110 launched can directive reflectors 100, again from inner surface 104 reflections and the light of directive reflector 100 penetrates the position of opening 106 and all can.Therefore, the utility model is not particularly limited the arrangement mode or the relative position of these light emitting diodes 110.In one embodiment, light emitting diode 110 can be arranged in the inner surface 104 of reflector 100 in the annular arrangement mode, and as shown in Figure 2, it illustrates is the front view of Fig. 1 LED source.In another embodiment, light emitting diode 110 can also be arranged in the inner surface 104 (not showing) of reflector 100 with irregular arrangement mode.
What deserves to be mentioned is that the light emitting diode 110 that is disposed on the inner surface 104 of reflector 100 is to be selected from ruddiness (red), green glow (green), blue light (blue), white light (white), dark green light (cyan), gold-tinted (yellow), tangerine light (magenta) light emitting diode and combination thereof.In other words, be disposed at light emitting diode 110 on the inner surface 104 of reflector 100 and can be light emitting diodes a kind of, two kinds, three kinds or more kinds of coloured light, it can be decided on the required coloured light of light source.For example, if need this LED source 120 to send white light, the light emitting diode 110 that then can select to be disposed on the inner surface 104 of reflector 100 is all white light (white) light emitting diode.Or, select the light emitting diode of ruddiness (red), green glow (green), three kinds of coloured light of blue light (blue) to be arranged on the inner surface 104 of reflector 100, make these three kinds of light colour mixtures that light emitting diode produced form white light.Same, if need this LED source 120 to send other kind coloured light, can also from ruddiness (red), green glow (green), blue light (blue), white light (white), dark green light (cyan), gold-tinted (yellow), tangerine light (magenta) light emitting diode, select suitable light emitting diode colour mixture to blend together desirable coloured light.
From the above, the utility model is that the light that utilizes a plurality of light emitting diode 110 collocation reflectors 100 to make light emitting diode 110 be launched can be concentrated, thereby makes LED source 120 have enough brightness.Therefore, LED source of the present utility model can solve the problem that traditional LED source has luminance shortage.In addition, the utility model does not need to adopt high electric energy to make it shinny to light emitting diode 110 yet, therefore except saving the electric energy, can make the light source overall volume can not become quite huge because of the design of other external circuit of needs yet.
LED source 120 of the present utility model also can comprise at least one optical element 112 except above-mentioned light emitting diode 110 and reflector 100, it is that the light that is arranged at reflector 100 penetrates opening 106 places.This optical element 112 for example is image field lens (field lens), and it can make light emitting diode 110 more concentrated through the light 114 that reflector 100 reflects.
In addition, LED source 120 of the present utility model also comprises a cooling device 116, and it is the outside that is installed in reflector 100.This cooling device 116 can be arranged at the place, the back side of reflector 100, or is layed on the outer surface 102 of reflector 100.The heat energy that cooling device 116 can make LED source 120 be produced when running can be discharged in real time.
And LED source 120 of the present utility model can be applied on many products that need light source, for example can be applied in the light-source system of display, in the lighting apparatus, in the light units of special lighting effects or the like.
In sum, because of adopting the configuration of reflector and a plurality of light emitting diodes, make that the light of light emitting diode is concentrated, thereby LED source has enough brightness at LED source of the present utility model.In addition, do not make it shinny because of LED source of the present utility model need not use high electric energy, therefore except saving the electric energy, it is quite huge that the LED source overall volume also can unlikelyly become.
Though the utility model discloses as above with preferred embodiment; yet it is not in order to limit the present invention; those skilled in the art without departing from the spirit and scope of the present invention; can do a little change and retouching, thus protection scope of the present invention should with accompanying Claim the person of being defined be as the criterion.
