Abstract
The utility model provides a conical condenser lens device made of glass material specially used for LEDs (light emitting diodes). The conical condenser lens device is made of glass material. The conical condenser lens device can overcome the defects that the lens in the prior art is easy to age and yellowing, and severely affects the light transmittance, and the like.
Description
Technical field
The utility model relates to and being used for the collector lens device of led light source as illuminating product, relates in particular to a kind of taper collector lens device that is exclusively used in the led light source device.Material is the collector lens of the non-led light source special use of glass, can not constitute invalid to the art of this patent.
Background technology
Led light source product, particularly power type LED light source product are a kind of wide-angle unidirection luminous devices.When led light source was designed to the directional lighting shot-light, prior art need be modified to arrow beam of light with wide-angle scattered light with optical lens, to increase center light intensity (Lux/cd).
Fig. 1 shows that taper collector lens 2 is used for the use signal on the led light source device 1.Fig. 2 a-2c shows the multiple optical lens schematic diagram that is used for the led light source correction respectively, for example conical (Fig. 2 a), many tapers (Fig. 2 b) and square taper (Fig. 2 c).
Fig. 3 has expressed above-mentioned optical lens in the led light source device, revises the effect signal that light penetrates.Among Fig. 3, label 3 has been indicated the firing angle/center light intensity of led light source when not using above-mentioned optical lens, and label 4 has then been indicated the led light source firing angle/center light intensity that adopts behind the above-mentioned optical lens.
But the material that is used for the taper collector lens of led light source device in the prior art generally all is to be shaped through mold injection with transparent plastic.The problem of this product is: reach several ten thousand hours the service life of led light source and when work temperature very high, and the lens of plastic material just begin to wear out behind hundreds of hour, jaundice, transparency seriously descend, thereby cause the light sustainment rate of led light source to descend, influenced the light output of lamp, made the light deepening.
The utility model content
At the above-mentioned deficiency of prior art, the utility model provides a kind of taper collector lens device that is exclusively used in the led light source device, and the material of described taper collector lens device is a glass.
According to an embodiment of the present utility model, described taper collector lens device by a plurality of taper collector lenses in conjunction with forming.
According to an embodiment of the present utility model, this taper collector lens device also comprises the glass light cover, is arranged at the front end of described led light source device, and wherein, described glass light cover and described taper collector lens are formed integral type.
Thereby the utility model has overcome easily wearing out, turning to be yellow of lens of the prior art by the taper collector lens device that adopts glass and has had a strong impact on defective such as light transmittance.Particularly, the main component of glass is silica (SiO
2), having good transparency, hardness also is difficult for oxidation and aging, can variable color yet, can not burn, characteristic is highly stable.Easily aging based on the lens of plastic material, turn to be yellow and have a strong impact on light transmittance.
The technology and the known technology of the glass optics collector lens of other purposes (non-LED illumination), irrelevant with the enforcement and the protection of the art of this patent.Can not constitute invalid to the art of this patent.
Should be appreciated that the above generality of the utility model is described and the following detailed description all is exemplary and explanat, and be intended to provide further explanation for as claimed in claim the utility model.
Description of drawings
Comprise that accompanying drawing is for providing the utility model further to be understood, they are included and are constituted the application's a part, and accompanying drawing shows embodiment of the present utility model, and play the effect of explaining the utility model principle with this specification.In the accompanying drawing:
Fig. 1 shows the use legend of the led light source device and the collector lens of prior art.
Fig. 2 a-2c shows the schematic structure of the optical lens that is used for the led light source correction of multiple prior art.
Fig. 3 shows the taper collector lens is revised the effect of light ejaculation in the led light source device schematic diagram.
Fig. 4 shows the glass material taper collector lens device that is exclusively used in the led light source device according to of the present utility model.
Fig. 5 a-5b shows the cutaway view according to two embodiment of the taper collector lens device that is exclusively used in the led light source device of the present utility model.
The specific embodiment
Now embodiment of the present utility model will be described with reference to the drawings in detail.
Fig. 4 shows the glass material taper collector lens device that is exclusively used in the led light source device according to of the present utility model.As shown in Figure 4, this taper collector lens device comprises a taper collector lens 5, is arranged on the led light source device in the mode of the bigger bottom of area away from the led light source device.The material of this taper collector lens device is a glass.Concrete set-up mode can be referring to Fig. 1.This taper collector lens device is one and basic is real core body, has that (φ is a) greater than the tapering (θ) of (φ b), and certain height (H) is arranged.Can be designed to cavity (C) in the middle part of real core body, in order to revise the light curve of output.
According to a preferred embodiment of the present utility model, taper collector lens device can be by one or more taper collector lenses in conjunction with forming.
According to another preferred embodiment of the present utility model, this taper collector lens also can combine with the glass light cover of reflectoscope, is designed to the product that one or more taper collector lenses combine with the glass light cover, as shown in Fig. 5 a and Fig. 5 b.
The utility model mainly is that the material of the tapered optical lens of the led light source special use of prior art has been implemented innovation and improvement.Particularly, the product of this utility model uses glass to make, and can also can directly make the taper collector lens on the headlight door of shot-light by one or more taper collector lens combinations.
Those skilled in the art can be obvious, can carry out various modifications and variations and not depart from spirit and scope of the present utility model above-mentioned exemplary embodiment of the present utility model.Therefore, be intended to make the utility model to cover to drop in appended claims and the equivalence techniques scheme scope thereof to modification of the present utility model and modification.
