Problems solved by technology

[0004] The invention belongs to a light distribution reflector for LED light source street lamps, including a plurality of integrated module type LED light source street lamp light distribution reflectors, an array type LED light source street lamp reflector, which can form uniform rectangular spot lighting, and is characterized in that it includes LED The light source, multi-curved high-order aspheric reflector, and the surface shape of the high-order aspheric reflector can be considered as a polynomial aspheric term added to the reference quadric surface. The technical problem mainly solved by the present invention is: Due to the lack of axiality and poor lighting effect, a modular LED street light reflector that can change the luminous characteristics of modular LEDs is proposed in view of the characteristics of the LED light source's luminous consistency.

Embodiment Construction

[0046] specific implementation plan

[0047] In the figure: 1. is the light source or the position of the light source; 2. is the light reflector, the frame or frame (W) of the light reflector, A.B.C.D.E. are all reflective areas. G.F is the LED light-emitting surface. The angle A1 between the GF is 25 ° to 50°. The included angle A3 between the lamp table surface F and the reflective surface D is 10° to 43°. The included angle A7 between the lamp table surface F and the reflective surface C is 50° to 90°. The included angles of the reflective A area are A4= 65°, A5=153°, A6=69°, A2=47°, the vector height Z of reflective area A=0.0mm, the vector height Z of reflective area B=0.4mm, and the vector height Z of reflective area C=02mm. The vector height Z=0.0mm of the reflective area D. The vector height Z=0.0mm of the reflective area E. The reflective surface (1)(2)(3)(4)(5) is an arc surface structure,

Abstract

The inventive LED light source road lamp light-distributing reflector includes a plurality of integrated module group type LED light source road lamp light-distributing reflector; array type LED light source road lamp reflector capable of forming homogeneous rectangle luminous spot lighting; LED light source; multi-curve high order aspheric surface reflector, whose surface shape can be considered as benchmark quadric added with aspheric surface polynomial item. The invention principally resolves the technical problems that the illuminating effect is bad due to the LED light-emitting axiality, by an innovate design of the light-distributor, the LED axial light beam transmits to a specific direction in a homogeneous light form after passing the light distributor, to obtain an unexpected remarkable effect, thereby effectively solving the problem of axial LED light, effectively solving the technique difficult problem of bad concentration and illuminating effect of the LED module light source road lamp, and meeting or exceeding the illumination level lighting products lighting technology index requirements and the actual use results.

Description

technical field [0001] The invention belongs to a lamp accessory, in particular to a module LED light source road lamp accessory product. Background technique [0002] At present, with the maturity of LED chip and packaging technology, energy saving, environmental protection and long life are the salient features of LED, and its LED solid-state lighting has become the current trend. In terms of application, especially in road lighting, the axial direction of LED light It is difficult to obtain the ideal lighting effect and meet the requirements of lighting products. Because the spotlight cup technology of the existing technology cannot be applied to the LED solid-state lighting Requirements, after the company has completed the heat dissipation problem of high-efficiency LEDs, it is urgently needed to solve the problem of the axiality of LED light emission before developing it for lighting and lamps. Contents of the invention [0003] The purpose of the present invention i...
