Two, background technology
In background technology, the LED Down lamp has been applied to the room lighting field at present, and this lamp is adopted LED packaged chip direct irradiation usually, and light source is one or more spot lights, and the light order of reflection is many, and reflective lighting illumination intensity loss 30% is prone to produce dazzle simultaneously.
Three, utility model content
The purpose of the utility model is a kind of mixed light type LED Down lamp of development, also is a kind of area source LED Down lamp.Better solve the low and big problem of light source heat radiation difficulty of light efficiency, be convenient to the many variety production of large-scale industrialization.
It is (simultaneously referring to accompanying drawing) that the utility model solves the technical scheme that its technical problem adopted: mixed light type LED Down lamp; Form by led light source on the lamp body 4 and lamp tube 9; It is characterized in that: in lamp body, blue led light source 4 is fixed on the pcb board 6 with cylindric optical mixing cover 2, links to each other with radiator 7; The light-passing board 3 that has yellow fluorescent powder places in the plastics lamp housing guard shield 1 and is socketed on the optical mixing cover 2, and the radiator 7 through screw 8 and heronsbill type solid aluminum section bar is locked as a whole.
The utility model solves the technical scheme that its technical problem adopted and also comprises:
Described mixed light type LED Down lamp is characterized in that: reflective surface adopts curved-surface structure and one section curved-surface structure that three sections facets form from top to bottom in the lamp tube 9; Wherein in three sections facets, facet reflecting piece 10 levels are connected to one section annular, and three sections annular curved-surface structures are formed in facet reflecting piece 10 stack that interlaces so up and down; In other one section curved-surface structure, be up-small and down-big round platform tubular.
Alternatively describe: adopt optical mixing cover that the light of a plurality of light sources is mixed, the light through light-passing board is evenly distributed.Described light fixture is characterized in: 1>radiator places the pcb board back side; 2>radiator adopts heronsbill type aluminium section bar; 3>light-passing board is for adding the flourescent sheet of fluorescent material; 4>reflective surface adopts three sections facets and one section curved-surface structure in the lamp tube; 5>lamp tube height 135mm and opening diameter 112.5mm.
Advantage of the utility model and effect:
1, the optical mixing cover of processing owing to high reflecting material MCPET, primary event can significantly reduce repeatedly the loss that the light reflection causes, and heightens the mixed effect of light.This light fixture adopts the optical mixing cover light-mixing structure, is widely used in all kinds of room lightings.
2, because radiator is close to the pcb board back side, the heat of light source can partly be delivered on the radiation tooth through the radiator central entity fast, and radiating effect improves greatly.
3, radiator adopts heronsbill type aluminium section bar, and convenient for production, thermal conductivity is good, and thickness that can be different according to the variation intercepting of power, is convenient to many variety production.
4, light-passing board has increased heat-dissipating space for adding the fluorescent plate of fluorescent material, has reduced the influence of light source heat to fluorescent material simultaneously, reduces light decay greatly.
5, reflective surface adopts three sections facets and one section curved-surface structure in the lamp tube, reduces the repeatedly reflection of light, has solved the bright circle light problem that occurs after the former light bright dipping simultaneously, improves the utilization rate of light greatly.
6, lamp tube height 135mm and opening diameter 112.5MM guarantee that the spot diameter that shines apart from plane, light source 1.6M place is 2M.
Four, description of drawings
Accompanying drawing 1 is a light fixture master TV structure sketch map, and accompanying drawing 2 is sectional structure sketch mapes of X-X among Fig. 1;
