Abstract
The invention discloses a lighting emitting optical lens that designs the face type of the optical lens according to launch angle, adopts lighting emitting material; mixing lens material with lighting emitting material and infecting mold or hot compacting to equally disperse the light emitting fluorescent dye into lens identity. The invention is mainly used in light emitting diode lamp. The invention makes the light equal and simplifies the structure of high intensity light emitting diode lamp.
Description
Technical field
The present invention relates to a kind of optical element, specifically relate to a kind of illuminated luminous optical lens, these lens by rayed after, can change the spectrum that penetrates light, according to face type and formula materials different in the illuminated luminous optical lens, obtain the required particular transmission angle and the light of spectrum.
Background technology
Traditional optical lens all is water white, is the optical element that is made of the certain surface type, its effect be light by certain refraction after or focal imaging or disperse projection.And along with the continuous development of science and technology, new type light source continues to bring out, as large-power light-emitting diodes.Therefore, the conversion of light is required more and more higher, press for and have multi-purpose optical element and satisfy, such as can being subjected to after the rays pass through lens according to exciting, and change its emission angle, thereby obtain needed light.But optical lens of the prior art all is difficult to satisfy above-mentioned requirements.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical matters, and a kind of illuminated luminous optical lens is provided.Require to design the face type of optical lens according to emission angle, can be sphere also can be aspheric surface; Select the specific optical excitation material that is subjected to for use according to the spectrum of light source light spectrum and institute's light requirement then, such as be subjected to blue-light excited for white light be yellow fluorescent powder, be subjected to the rare-earth trichromatic fluorescent powder of ultraviolet excitation etc.; In certain proportion lens material such as PC, PMMA, PS etc. are mixed mutually with being subjected to the optical excitation material, injection moulding or hot-forming again makes be evenly distributed in the lens body by optical excitation fluorescent powder.
The present invention is mainly used on the high strength LED light lamp, utilize light emitting diode to do basic light source, irradiate light is to illuminated luminous optical lens, be evenly distributed on and worked by optical excitation fluorescent powder, change the spectrum of the light of light emitting diode, transmit designed light afterwards with special spectrum.Change around light emitting diode, to pile up in the past and be subjected to structure very uniformly of optical excitation fluorescent powder, make the even bias free of light that transmits, also simplified the structure of high strength LED light lamp simultaneously, assemble conveniently, help reducing production costs.

Accompanying drawing 1 is the structural representation of a kind of high strength LED light lamp in the prior art;
Accompanying drawing 2 is structural representations of another kind of high strength LED light lamp in the prior art;
Accompanying drawing 3 is a kind of structural representations of the present invention;
Accompanying drawing 4 is another kind of structural representations of the present invention;
Accompanying drawing 5 is a kind of structural representations of the embodiment of the invention;
Accompanying drawing 6 is another kind of structural representations of the embodiment of the invention.
Number in the figure is: 1-illuminated luminous optical lens body 2-tube core; 3-support 4-is subjected to optical excitation fluorescent powder.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: referring to Fig. 3 and Fig. 4, the present invention is evenly distributed with to be subjected to optical excitation fluorescent powder 4 in lens body 1.Referring to Fig. 5 and Fig. 6, illuminated luminous optical lens of the present invention is assemblied on the support 3 of high strength LED light lamp, several tube cores 2 are being set on the support 3 and between the lens body 1, the blue light illumination that tube core 2 light-emitting diodes tube cores send makes the yellow fluorescent powder in the lens be subjected to send the white light that can be used for throwing light on behind the photograph to lens of the present invention.
Referring to the structure of high strength LED light lamp in Fig. 1 and Fig. 2 prior art, and compare, the designs simplification of high strength LED light lamp is a lot of as can be known, and the assembly technology that brings is also simple a lot.What particularly point out is: fluorescent powder of the prior art need add diffusant (seeing fluorescent powder 4 among Fig. 1, Fig. 2), and this has reduced luminescence efficiency beyond doubt.In addition, because it is inhomogeneous piled up by optical excitation fluorescent powder, usually make that the light that transmits has deviation.Lens of the present invention have solved above-mentioned two large problems well, the irradiate light that diode chip sends is to illuminated luminous optical lens, be evenly distributed on and worked by optical excitation fluorescent powder, not only change the blue light that light emitting diode sends and made it to become the white light that can be used for throwing light on, and can be according to different application scenarios, design the not lens of coplanar type, to adapt to different emission angle requirements.Launch designed light afterwards with particular transmission angle and spectrum.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
