For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high-power LED light source light diffuser is characterized in that: comprise be contained in high-power LED light source anterior and with high-power LED light source institute emitting parallel light to around the light diverging lens that fully spreads; Light diverging lens front is provided with a plurality of zigzag fins that the parallel rays that is incident upon on the light diverging lens is carried out different angles and direction refraction.
The quantity of described smooth diverging lens is a plurality of, and a plurality of smooth diverging lens is assembled into one also integral installation side by side in the high-power LED light source front portion.
Described smooth diverging lens is washboard shape lens, and set on the described washboard shape lens is the symmetrical center line left-right symmetry at a plurality of zigzag fins with the geometric center lines of washboard shape lens, and the zigzag fin is the linear pattern fin; Angle α between the described zigzag fin and the washboard shape lens back side increases from the inside to the outside gradually from described symmetrical center line, and the critical angle θ of the angle α between each the zigzag fin and the washboard shape lens back side when all being not more than described parallel rays and on this zigzag fin total reflection taking place.
Described smooth diverging lens is target shape lens, and a plurality of zigzag fins set on the described target shape lens are a plurality of circular fin of round dot for the geometric center point with described target shape lens; Angle α between the described zigzag fin and the target shape lens back side increases from the inside to the outside gradually from described round dot, and the critical angle θ of the angle α between each the zigzag fin and the target shape lens back side when all being not more than described parallel rays and on this zigzag fin total reflection taking place.
Described washboard shape lens are rectangle, circle, ellipse or regular polygon.
Described target shape lens are circle or regular polygon.
The upper surface of described zigzag fin is a concave arc surface.
The back side of described smooth diverging lens is the plane.
Described smooth diverging lens scioptics support is fixed on the radiator that high-power LED light source installs.
The utility model compared with prior art has the following advantages:
1, modern design rationally, cost is low and processing and fabricating convenient, earlier washboard shape lens are contained in the high-power LED light source front portion during installation, installing lampshade then additional gets final product, thereby need not existing LED fitting structure is done bigger adjustment, only need lampshade is laid down, the corresponding again light diverging lens that installs additional on led light source gets final product.
Practical problems such as 2, installation laying convenience and result of use are good, and the irradiation area area that can effectively solve the high-power LED light source existence is little, light is dazzling.
3, occupation mode is flexible, and structure is various, can satisfy the concrete user demand of different use occasions, and wherein washboard shape lens can stretch the LED area source on the same line, but thereby the strip light source of the light source solar simulated lamp after spreading; Target shape lens can with the LED area source to around evenly spread thereby the light source energy simulating chamber interior flat light source of institute after spread.
4, applied widely and practical value is high, expanded the scope of application of led light source significantly, given full play to advantages such as luminous efficiency height that led light source had, radiationless, long service life, thereby relatively extensive market prospects, social benefit and economic benefit.
In sum, the utility model is novel in design rationally, cost is low, easy for installation and result of use is good, can effectively solve practical problems such as the irradiation area area that high-power LED light source exists is little, light is dazzling, has expanded the scope of application of led light source significantly.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
