Description

Integrated packaged type high-power LED streetlight lens
Technical field
The utility model relates to a kind of lighting device, particularly a kind of optical lens of integrated packaged type high-power LED street lamp illumination.
Background technology
Along with improving constantly of LED luminous efficiency, led light source is just demonstrating application prospects with its significant advantage, as road lighting, tunnel illumination, Landscape Lighting etc.High-power LED light source is a hot research in recent years in the application of lighting.The high-power LED light source of often saying generally is meant the led light source of 1W ~ 3W at present.Because be subjected to semiconductor manufacturing and envelope shape technology limitation, the power of single LEDs light source is less, this has seriously restricted exploitation and the application of led light source in light fixture.The way that realizes at present high-power LED street lamp mainly contains two kinds, a kind of be tens of combinations even hundreds of LEDs light source to form several light emitting modules, a this method light source number is many, cost height, volume are big, and complex circuit designs; Another kind is directly the plurality of LEDs chip to be encapsulated in a pedestal the inside directly to obtain 75W, 100W even more powerful integrated packaged type high-power LED light source.This dual mode all inevitably will be with the major consideration of luminous intensity distribution design as Design of Luminaires.
The common method of the luminous intensity distribution of LED street lamp design is to adopt lens to carry out the secondary optics design at present.Light distributing method at the combined high-power LED street lamp is many.Integrated packaged type high-power LED light source has brought light too concentrated and produce the problem of dazzling the eyes in the luminous energy of the desirable big intensity of output.How to make light shine the zone of requirement uniformly, form uniform rectangular illumination light shape on the road surface, design is had higher requirement to luminous intensity distribution.
Summary of the invention
The utility model mainly solves the luminous intensity distribution problem of integrated packaged type high-power LED street lamp, and a kind of good illumination effect, efficiency of light energy utilization height, energy-conservation tangible integrated packaged type high-power LED streetlight lens are provided.
The technical solution of the utility model:
Integrated packaged type high-power LED streetlight lens, make by transparent glass material, comprise pedestal, described pedestal is provided with the aspheric surface body of the different illumination zone of control, described pedestal and aspheric surface body are integrative-structures, described pedestal and aspheric surface body are provided with the groove of placing led light source, and it is characterized in that: the curved surface of described aspheric surface body is formed by middle circle cylinder and two ends sphere.
Further, described groove is made up of the curved surface of the face of cylinder and smooth transition, and its openings of sizes is slightly larger than the diameter of led light source.
Further, the design of the periphery of described pedestal has had spacing and cylindrical hole fixation.
The face of cylinder of aspheric surface body described in the utility model is controlled different illumination zones respectively with sphere.Described groove can make the launching spot of the sub-circular oval hot spot of growing up evenly penetrate; The openings of sizes of groove is slightly larger than the diameter of led light source, avoids dispersing of light.Pedestal and aspheric surface body are an integral body, and periphery has four cylindrical holes, play position-limiting action, are convenient to fixedly mount lens.
Advantage of the present utility model:
1, light shape is good.According to the characteristics of road lamp light distribution, by the CAE method the relevant luminous intensity distribution parameter of lens is optimized analysis, make the lens design satisfy the road lighting requirement, and simple in structure, easy to manufacture.
2, efficiency of light energy utilization height, energy-conservation obvious.The openings of sizes of pedestal upper groove has been avoided dispersing of light greater than the diameter of led light source; Reasonably the design of the face of cylinder and sphere helps making full use of of luminous energy, has improved the utilization rate of luminous energy to greatest extent, and is energy-conservation obvious.
3, convenient fixing.Pedestal and aspheric surface body are the integrated design, and periphery has cylindrical hole, help the fixed installation of lens, have improved the reliability of light fixture.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, integrated packaged type high-power LED streetlight lens, make by transparent glass material, comprise pedestal 1, described pedestal 1 is provided with the solid aspheric surface body 2 of the different illumination zone of control, described pedestal 1 is integrative-structures with aspheric surface body 2, has the groove 3 of placing led light source on described pedestal 1 and the aspheric surface body 2, and the curved surface of described aspheric surface body 2 is formed by middle circle cylinder and two ends sphere.
Described groove 3 is made up of the curved surface of the face of cylinder and smooth transition, and its openings of sizes is slightly larger than the diameter of led light source.
The periphery of described pedestal 1 has had the cylindrical hole 4 of spacing usefulness.
The face of cylinder of aspheric surface body 2 described in the utility model is controlled different illumination zones respectively with sphere.Described groove 3 can make the launching spot of the sub-circular oval hot spot of growing up evenly penetrate; The openings of sizes of groove 3 is avoided dispersing of light greater than the diameter of led light source.Pedestal 1 is an integral body with aspheric surface body 2, and periphery has four cylindrical holes 4, plays position-limiting action, is convenient to fixedly mount lens.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
