Luminous diode illuminating light source device
Technical field
The present invention relates to a kind of luminous diode illuminating light source device, major part is to use the illumination at limited area, can be applicable to indoor night-light, exhibit illuminating lamp, flashlight, outdoor traffic sign lamp, vehicle lamp, billboard etc.
Background technology
For efficient power saving, high life lighting device are provided, light emitting diode replaces conventional bulb gradually, but the wide-angle light source that light emitting diode four penetrates, need higher light-collecting component, to be fit to the low-angle lighting use, as the needs of small sizes such as indoor night-light, flashlight, exhibit illuminating lamp, outdoor traffic sign lamp, vehicle lamp, billboard illumination.
General luminous diode illuminating light source all is to use a plurality of light emitting diode bulbs arrangements to be planar array, wherein inside has light emitting diode to produce four to penetrate light, four of part is penetrated light toward the bulb top and through behind the convex lens, reflect slightly parallel to glazing, and four of side direction penetrate wide critical angle all around in total reflection, or being folded to side direction wide-angle light all can't be used effectively in illumination, is illustrated in figure 1 as the light harvesting situation of conventional bulb, and visible light harvesting effect still has the space of improvement.As the patent of US4767172, with reference to Fig. 2, this Organic Light Emitting Diode need pass through air scioptics again, and light beam to air, passes the lens material by light emitting diode again, and this two interface can cause light loss; And the reflectance coating around the lens outside is not protected and fixing, varies with temperature down delamination problems for a long time; The base area of lens is also less, so the optical axis vertical precision that is affixed on the substrate is difficult for high.As the light emitting diode light harvesting design (US4770514 patent case) that David was proposed in 1986, as shown in Figure 3, the floor space that its optical module is attached on the substrate is little, and optical axis is difficult for aligning; And reflectance coating is exposed to the outside, varies with temperature for a long time and can come off gradually; Aspect production, the Organic Light Emitting Diode of this patent case US4770514 does not cooperate The Automation Design, is difficult for a large amount of production.
Summary of the invention
Main purpose of the present invention, be to solve above-mentioned defective, avoid the existence of above-mentioned defective, the invention provides a kind of luminous diode illuminating light source device, solve the phenomenon that its light beam of prior art is inhomogeneous and disperse, especially when a plurality of miniature bulbs are assembled, more can significantly improve the parallel accuracy of each optical axis, reduce the difficulty that aligns optical axis in the prior art.
Another object of the present invention is to provide a kind of luminous diode illuminating light source device,, not only can assemble light beam and also can coat reflectance coating on the total reflection film of this aluminium or silver with high molecular forming, prevents that reflectance coating from coming off.
For realizing above-mentioned purpose, a kind of luminous diode illuminating light source device provided by the present invention comprises a base plate carrying light emitting diode, reflector platform and lens.At first on this reflector platform, form a plurality of recessed basin speculums, saturating empty and saturating empty peripheral bottom surface, the central bottom surface of this recessed basin speculum is smooth in substrate, has one group of LED crystal particle on the substrate of hollow part position, and the concave part of recessed basin speculum is the parabola completely reflecting mirror, the optical axis of its concave basin speculum and light emitting diode are arranged center-aligned, because the area of base is bigger, make a plurality of miniature bulbs when assembling, depth of parallelism height between each optical axis, significantly reduce the difficulty that aligns optical axis in the prior art, and on recessed basin speculum with high molecular forming one lens, these lens central authorities are convex lens, are a cone around the side, and central convex lens and cone all around are structure as a whole, with the hollow part position of high molecular forming in recessed basin speculum central authorities, and the lens bottom surface is affixed on substrate and coat one group of LED crystal particle; Can locate accurately during by an optical axis locating hole in assembling, this optical axis locating hole runs through the center of platform between this substrate and speculum, can change with the external form and the arrangement difference of reflector platform or a plurality of recessed basin speculums, can significantly improve its range of application.
Luminous diode illuminating light source device of the present invention, be to utilize lens and recessed basin speculum to compile light that light emitting diode four penetrates in equidirectional, the light that can assemble wide-angle becomes the stronger light of low-angle, become high-strength beam, obtain high efficiency and uniform light beam, especially can be used as the parallel benchmark of optical axis at big bottom reflection mirror platform, can be when a plurality of miniature bulbs be assembled, significantly improve the parallel accuracy of each optical axis, reduce the difficulty that aligns optical axis in the prior art, and cooperate the optical axis locating hole to do location accurately, be beneficial to the automation assembling.
And on recessed basin speculum with high molecular forming one lens, the concave part of this recessed basin speculum plates the total reflection film of layer of aluminum or silver, wherein lens central authorities are convex lens, around the side is a cone, central authorities' convex lens and cone all around are structure as a whole, optical module can be used plastics forming, but the assembling automation, so the production height.
