Abstract

The utility model discloses an optical lens that shins when being exposed to light and can be characterized in that the body of the lens (1) is distributed evenly with optical excitation phosphors (4). The shape of the surface to the optical lens can be designed according to requirements of the radiation angle. Then special optical excitation materials can be selected according to light source spectrum and required spectrum of desire lights. Mix the lens materials such as PC, PMMA and PS with optical excitation materials and then shape the structures by employing injection and hot-press. In this way, the optical excitation phosphors will be evenly distributed in the main body of the lens. The utility model is mainly used in high intensity light-emitting diode (LED). The light beam of the LED on the optical lens will cause the phosphors to perform reactions. The spectrum of the light of the LED will be altered, and then it will emit lights with specified spectrum. The utility model is an innovation of the traditional LED that the phosphors are not uniformly distributed, so that accuracy of lights emitted can be ensured, and the structure of LED is also simplified for ease assembly and lowered production cost.

Description

Illuminated luminous optical lens

Technical field

The utility model 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 utility model mainly is to solve 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 utility model 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.

Number in the figure is: 1-illuminated luminous optical lens body; The 2-tube core; The 3-support; 4-is subjected to optical excitation fluorescent powder.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: referring to Fig. 3 and Fig. 4, the utility model is to be 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 utility model 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 the utility model lens.

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.The utility model lens 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 utility model.Obviously, the technical solution of the utility model 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 the disclosed content of the utility model all should be thought protection domain of the present utility model.

Claims

1. illuminated luminous optical lens is characterized in that being evenly distributed with in described lens body (1) and is subjected to optical excitation fluorescent powder (4).
