Abstract
The utility model discloses a secondary optical light distribution device of a high-power LED street lamp, and relates to the technical field of secondary optical light distribution. The secondary optical light distribution device of the high-power LED street lamp is provided with a base plate 1 which is evenly provided with a plurality of light sources 2, and the light-emitting surface of each light source 2 is provided with an optical lens 3; and the optical lenses 3 are fixed at the center positions of the light sources 2 by fixing cover plates 4. The device has the beneficial effects that the production technique is simple, and the production cost is lowered; and the light distribution effects is good, and the roadway lighting light distribution requirements are realized.
Description
Technical field
The utility model relates to street lamp secondary optics luminous intensity distribution technical field, specifically is a kind of high-power LED street lamp secondary optics light distribution device.
Background technology
Existing LED street lamp owing to consider the inhomogeneity problem of distribution of light sources, adopts the led light source below ten watts more than a watt mostly, though the part has solved the inhomogeneity problem of illumination patterns, overall power is on the low side.Some high-power LED street lamps are also arranged, but these high-power LED road-light light-source distributing homogeneities are bad, light distribution effect is poor when rainy weather especially, and manufacturing cost height simultaneously can not adapt to the needs in current street lighting market.
Summary of the invention
In order to solve the shortcoming of above-mentioned prior art, the utility model provides a kind of high-power LED street lamp secondary optics light distribution device, can improve the light distribution effect of high-power LED street lamp, satisfies the demand of night illumination.
The utility model is realized with following technical scheme: a kind of high-power LED street lamp secondary optics light distribution device, comprise substrate, some light sources are installed on the substrate, and described light source is a high-power LED lamp, and correspondence is equipped with optical lens on the light-emitting area of each light source.
The beneficial effects of the utility model are: production technology is simple, has reduced production cost; Light distribution effect is good, reaches the requirement of road lighting luminous intensity distribution.
Description of drawings
Be described further below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the utility model vertical view;
Fig. 3 is an assembling schematic diagram of the present utility model.
Among the figure: 1, substrate; 2, light source; 3, optical lens; 4, securing cover plate.
As shown in Figure 1, secondary optical light distribution device of high-power LED street lamp, one substrate 1 is arranged, at substrate 1 some light sources 2 are installed, light source 2 is LED lamps of power 〉=30W integration packaging, an optical lens 3 is installed on the light-emitting area of each light source 2, and securing cover plate 4 is fixed on optical lens 3 center of light source 2.
As shown in Figure 2, optical lens 3 of corresponding installation on the light-emitting area of each light source 2, securing cover plate 4 is fixed in optical lens 3 center of light source 2. In the present embodiment, securing cover plate (4) is one and has equally with optical lens (3) shape, is slightly less than the cover plate of the circular hole of optical lens (3), with screw securing cover plate (4) is fixed on the substrate (1).
As shown in Figure 3,8 LED lamps are as example in Fig. 2, and 8 LED lamps consist of the light source modules, and light source module 2 is divided into two rows and evenly is installed on the substrate 1, and each LED lamp center is equipped with optical lens 3. The light source module can adopt other compound mode in fact, and power is more little, and the quantity of LED lamp is more many, and the quantity of corresponding optical lens 3 also increases, otherwise reduces. Optical lens 3 can be the lens that optical glass is made, and also can be the lens of optical plastic compacting. In addition, optical lens 3 also can require to adopt the lens that improve the uniformity and control lighting angle according to specific road lighting, being not limited to the circular configuration profile that this specification figure is described, also can be lens or the erose lens of ellipsoidal structure. The described figure of this specification just for the drawn figure of principle of this utility model of explanation clearly with analysing, and non-limiting its profile and purposes, and variation on this basis designs should be in the scope of this utility model.
The specific embodiment: at first the utility model is assembled according to Fig. 3.Owing to consider the heat dissipation problem of LED, when installing, on each light source 2 corresponding back side a heat pipe is installed at least, heat pipe adopts the vacuum heat-pipe of copper or aluminum, this heat pipe is processed into the shape of " Z " font or " 7 " font, and the angle of its bending part is more than or equal to 90 degree.One end of heat pipe contacts with substrate 1, the other end and street lamp housing contacts.Between LED lamp substrate and substrate 1, coat hot silicone grease with the increased thermal conductivity energy.The a large amount of heat energy that produced by the LED lamp substrate pass to the street lamp shell fast by the heat pipe on the substrate 1 like this, and by the street lamp shell heat that accumulates in the light fixture are delivered in the air fast and effectively.
The foregoing description only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description, need not also can't give exhaustive here all embodiments.
