The specific embodiment
As depicted in figs. 1 and 2; The utility model comprises lens body; The outer surface of said lens body is the free form surface 1 that is used for luminous intensity distribution; The bottom surface of said 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 said hemisphere face 2 on the bottom surface of said lens body are provided with card base 5, and the two ends, bottom surface of said lens body are connected with through joint pin 3 and are used for lens body is installed to the feet 4 on the substrate, and said joint pin 3 is connected between said free form surface 1 and the feet 4.
As depicted in figs. 1 and 2, in the present embodiment, the outer contour shape of said lens body is a similar mountain range shape.Said free form surface 1 is asymmetric free form surface.The bottom surface of said lens body is the plane with Non-optical surfaces.Being shaped as of said feet 4 is square.Said card base 5 be shaped as arc.
The utility model in use; The LED module array simple arrangements that whole lamp only needs to have the rectangle luminous intensity distribution gets final product on a flat board; 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 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, accomplish luminous intensity distribution, the lambert's type hot spot that sends is made into rectangular light spots led light source; Not only effectively must contain dazzle, also can realize the even distribution of light.Arc card base 5 is used to guarantee when assembling the concentricity between lens and led light source within certain scope in the lens, avoids because the off-centre during assembling cause that the hot spot left and right sides is inhomogeneous, thereby light intensity is inconsistent.Joint pin 3 is mainly used in and connects feet 4 and free form surface 1, is used for lens arrangement to substrate.
Wherein, What led light source sent is that this part light that the meeting of 60 °～90 ° of scopes produces dazzle need adopt and cuts the light design along x direction beam angle, being the light of 60 °～90 ° of scopes along x direction beam angle, and convergence in the middle of the road surface; Be distributed in along the x direction to become with optical axis on 60 °～45 ° road surfaces in the scope; To eliminate dazzle, wherein the light at 60 ° of angles is rim ray, the edge of the hot spot of corresponding x direction.Because the exit surface of lens, in the x direction along road, its outgoing beam is dispersed; And a very big visual angle is arranged, and its section should be negative lens, in the y direction of 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: 180 ° the light beam 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; On the y direction, be made 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 comparatively even light distribution, and the LED street lamp is easy to generate dazzle, the unequal defective of illumination patterns and deficiency in the prior art thereby solved effectively.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of the utility model technical scheme according to the utility model technical spirit.
