Abstract
The utility model discloses a LED street lamp, which comprises a base plate, one or more LED wafer(s) is (are) fixed on the frontal surface of the base plate, a light distribution structure is installed on the frontal surface of the base plate, and the light distribution structure is composed of one or more lens(es), and each lens is corresponding to one LED wafer. Because the LED wafer is directly sealed in the transparent light distribution structure, and the light emitted by the LED wafer(s) directly penetrates through the light distribution structure and radiates to all around, and thereby the luminous energy loss is greatly reduced; in addition, the LED street lamp has the advantages that the structure is simple, the LED wafer(s) is (are) not required to be sealed in the light cup firstly, and then covered by using the light distribution cover, therefore, the volume of the LED street lamp can be reduced, and the production cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of lighting device, particularly a kind of high-brightness LED street lamp that is used for road lighting.
Background technology
Energy problem is a pressing problem that is troubling countries in the world, general illumination especially road lighting has accounted for sizable ratio in consume electric power, the last century Mo appearance of white light LEDs attracts showing warm solicitude for of national governments and enterprise, becomes a hot topic in photoelectron, the illuminating engineering sciemtifec and technical sphere.The luminous energy that the incandescent lamp of the luminous energy that one 10～12 watts led light source sends and 35～150 watts sends is suitable, same illuminating effect LED is than conventional light source energy-conservation 80%～90%, people expect that white light LEDs becomes new lighting source of the 4th generation, reaches energy-conservation green illumination purpose.
The present general structure of LED street lamp is: be provided with circuit layer on the metal substrate one side, a plurality of LED lamp bodies are fixed on the one side that metal substrate is provided with circuit layer, link to each other with circuit layer by lead; Be fixed with heat sink at the metal substrate another side, be fixed with light distributing cap on metal substrate, the LED lamp body is located in the light distributing cap.The LED lamp body comprises Lamp cup, and uses the LED wafer of epoxy sealing in Lamp cup.The shortcoming of this LED street lamp is that light will just can shoot out by cup and lampshade, and through two secondary reflections and refraction, light loss is bigger, and loss can reach 15-20%, this LED lamp post structure complexity in addition, and volume is big, and production cost is higher.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of optical energy loss little, LED street lamp simple in structure.
For achieving the above object, the technical solution of the utility model is:
A kind of LED street lamp has substrate, substrate front side is fixed with one or more LED wafers, and described substrate front side is equipped with light distribution structure, and described light distribution structure is made up of one or more lens, and each lens is corresponding with a LED wafer.
Described lens surface is a convex surface.
The transparent body that described light distribution structure is formed in one.
Described substrate is metal substrate, ceramic substrate or fibre base plate.
Described substrate front side applies reflector layer.
Described substrate back is connected with heat-conducting substrate.
LED street lamp described in the utility model, because the LED wafer directly is sealed in the transparent light distribution structure, its light that sends directly passes light distribution structure and around the directive, has significantly reduced optical energy loss; LED lamp post structure described in the utility model in addition is simple, and the LED wafer does not need to be sealed in earlier in the Lamp cup, covers with light distributing cap again, can reduce the volume of LED street lamp like this, and reduces its production cost greatly.
Description of drawings
Fig. 1 is the utility model LED lamp post structure schematic diagram;
Fig. 2 is the structural representation of light distribution structure;
Fig. 3 is the structural representation of single lens on the light distribution structure.
The primary clustering symbol description
1 aluminium base 2LED wafer, 3 light distribution structures
4 lens, 5 heat-conducting substrates
The specific embodiment
See also Fig. 1 to Fig. 3, a kind of LED street lamp, have aluminium base 1, the aluminium base front at first is coated with insulating layer coating, again the coated with conductive layer, 36 LED wafers 2 are fixed in the front, 36 LED wafers are divided into 6 groups, and 6 every group, the LED wafer is connected with conductive layer by lead, apply reflector layer on the aluminium base front side conductive layer, described aluminium base front is equipped with light distribution structure 3, and the transparent body that described light distribution structure is formed in one is made up of 36 lens 4, described lens are divided into 6 groups, every group 6, each lens is corresponding with a LED wafer, and the LED wafer is housed in the light distribution structure, lens surface is a convex surface, and the aluminium base back side is connected with heat-conducting substrate 5.
Described aluminium base can be replaced by other metal substrate, ceramic substrate or fibre base plate.
After LED street lamp described in the utility model was connected power supply, the light that the LED wafer sends had changed radiation direction after the refraction of the lens on the light distribution structure, enlarged the effective lighting scope, reduced the light loss consumption, compared, can reduce light loss 15-20% with existing LED street lamp.In addition because the positive last one deck reflectorized material that applies of aluminium base, it can further effectively utilize light source with through the light of light distribution structure refraction secondary reflection again.
Claims (6)
1, a kind of LED street lamp, have substrate, substrate front side is fixed with one or more LED wafers, it is characterized in that: described substrate front side is equipped with light distribution structure, and described light distribution structure is made up of one or more lens, and each lens is corresponding with a LED wafer.
