The specific embodiment
As depicted in figs. 1 and 2, the present invention includes lens body, the outer surface of described lens body is for being used for the free form surface 1 of luminous intensity distribution, the bottom surface of described lens body has the hemisphere face 2 of the indent that the centre of sphere and LED light source center coincide, the both sides that are positioned at described hemisphere face 2 on the bottom surface of described lens body are provided with card base 5, the two ends, bottom surface of described lens body are connected with for the feet 4 that lens body is installed on substrate by joint pin 3, and described joint pin 3 is connected between described free form surface 1 and feet 4.
As depicted in figs. 1 and 2, in the present embodiment, the outer contour shape of described lens body is similar mountain range shape.Described free form surface 1 is asymmetric free form surface.The bottom surface of described lens body is the plane with Non-optical surfaces.Being shaped as of described feet 4 is square.Described card base 5 be shaped as arc.
The present invention in use, the LED module array that whole lamp only needs to have the rectangle luminous intensity distribution simply is arranged on a flat board and gets final product, this LED street lamp is fairly simple aspect frame for movement, heat radiation, power supply control, and the LED module that the road lighting of different brackets highway and different pole height only need to increase varying number gets final product.Hemisphere face 2 is the plane of incidence of LED light source, the light that LED light source sends incides lens through hemisphere face 2, through the luminous intensity distribution of free form surface 1, divergence of beam is gone out again, complete the luminous intensity distribution to LED light source, the lambert's type hot spot that sends is made into rectangular light spots, not only effectively must contain dazzle, also can realize the even distribution of light.In lens, arc card base 5 is used for guaranteeing when assembling the concentricity between lens and LED light source within certain scope, and the bias when avoiding due to assembling cause that the hot spot left and right is inhomogeneous, thereby light intensity is inconsistent.Joint pin 3 is mainly used in connecting feet 4 and free form surface 1, is used for lens arrangement to substrate.
Wherein, the beam angle in the x-direction that LED light source sends is that this part light of the meeting generation dazzle of 60 °～90 ° of scopes need adopt a section light design, be beam angle in the x-direction the light of 60 °～90 ° of scopes, assemble in the middle of the road surface, be distributed in to become with optical axis in the x-direction on 60 °～45 ° road surfaces in scope, to eliminate dazzle, wherein the light at 60 ° of angles is rim ray, the edge of the hot spot of corresponding x direction.Exit surface due to lens, in the x direction along road, its outgoing beam is dispersed, and a very large visual angle is arranged, and its section should be negative lens, y direction at vertical road, its outgoing beam is assembled, and its section should be a positive lens, so the outer surface of lens body is set to asymmetric free form surface, its luminous intensity distribution is characterized as: the light beam of 180 ° that lambert's type LED light source is sent is being made into evenly distribution within 120 °～130 ° on the x direction, distribution curve flux is batswing tab and distributes; Be made on the y direction in 60 °～70 ° and evenly distribute; Thereby the sphere shape light that lambert's type LED is sent is made into rectangular light spots, has realized that light distributes comparatively uniformly, and in prior art, the LED street lamp easily produces dazzle, the unequal defective of illumination patterns and deficiency thereby effectively solved.
The above; it is only preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection domain of technical solution of the present invention.
