Description
Technical field
The utility model relates to a kind of light-emitting device of compound lens, relates in particular to a kind of compound lens light-emitting device for lighting of home light fixture that can realize the white light of light and shade stack and the effect of colored Bright folding.
Background technology
At present, along with the development of LED lighting engineering with in the extensive use of household lighting field, LED is not only as a kind of illuminating device, and as a kind of ornament, uses to a great extent.Such as head of a bed mini light night, crystal globe lamp, pen container lamp etc., be more and more subject to people's favor.Existing indoor lamp mainly contains four classes: LED bulb lamp, LED straight lamp, LED flat lamp, LED lamp affixed to the ceiling etc., these lamps are mainly all the lighting requirements that meets people, and do not possess more decoration and illuminating effect.Scheme of the present utility model has been broken and conventional only LED has been carried out to the mode of secondary light-distribution, and has adopted the mode of compound lens to carry out luminous intensity distribution three times to LED, can control accurately the light path of light, further realizes the stack of different hot spots and different colours.
Utility model content
The purpose of this utility model is to provide a kind of Overlay that can realize LED light and shade, meets the requirement of conventional illumination, sight illumination and decorative lighting, the light-emitting device based on compound lens for lighting of home light fixture simple in structure, production cost is lower.
The technical solution adopted in the utility model is: a kind of light-emitting device based on compound lens, comprising: pedestal, and described pedestal is disposed with the little groove of stairstepping and stairstepping big groove along the longitudinal direction in bottom; LED light source, described LED light source is welded on for dispelling the heat and laying the aluminium base of LED circuit, aluminium base and then be attached in base bottom surface by heat-conducting silicone grease; Lenslet, described lenslet fixes on by silica gel solid on the small boss on the little groove of stairstepping of pedestal, and presses to prevent that by pressing plate lenslet from moving left and right in installation process; And large lens, described large lens fix on by silica gel solid on the large boss of stairstepping big groove of pedestal.
In such scheme, base bottom also has cable hole, and cable hole one end is communicated with the little groove of stairstepping, and the other end is connected with the accommodating cavity of the power supply that is equipped with LED driving power.
In such scheme, the arrangement area of lenslet is less than the base area of large lens.
In such scheme, lenslet adopts PMMA(polymethyl methacrylate), PC(Merlon) or high-boron-silicon glass material.
In such scheme, large lens adopt transparent PMMA, PC or high-boron-silicon glass material.
In such scheme, pedestal bottom side outer edge is also provided with for pedestal being sticked to the EVA(ethylene-vinyl acetate copolymer of desktop) sticky pad, to prevent that pedestal from slidably reciprocating at desktop in operation.
The beneficial effects of the utility model are: owing to having adopted technique scheme, compound lens of the present utility model can be realized various symmetries and asymmetric hot spot Overlay, can meet various indoor environment lighting requirements, and the utility model is simple in structure, be easy to install, production cost is lower.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of light-emitting device based on compound lens, comprises pedestal 1, LED light source 4, aluminium base 5, lenslet 6 and large lens 7.Pedestal 1 is for providing LED to install and heat radiation, this pedestal 1 is disposed with the little groove 2 of stairstepping and stairstepping big groove 3 along the longitudinal direction in bottom, pedestal 1 bottom also has cable hole 11, cable hole 11 one end are communicated with the little groove 2 of stairstepping, and the other end is connected with the accommodating cavity 9 of the power supply that is equipped with LED driving power; LED light source 4 is welded on for dispelling the heat and laying the aluminium base 5 of LED circuit, aluminium base 5 and then be attached on pedestal 1 bottom surface by heat-conducting silicone grease; Lenslet 6 converges for the light that LED lamp pearl is sent, it fixes on by silica gel solid on the small boss on the little groove 2 of stairstepping of pedestal 1, and by pressing plate 8, press, to prevent that lenslet 6 from moving left and right in installation process, pressing plate can also block the solder joint on aluminium base 5 simultaneously; Described large lens 7 are uniformly distributed for the light that lenslet 6 is converged, and it fixes on by silica gel solid on the large boss of stairstepping big groove 3 of pedestal 1; Pedestal 1 bottom side outer edge is also provided with for pedestal 1 being sticked to the EVA(ethylene-vinyl acetate copolymer of desktop) sticky pad 10, to prevent that pedestal 1 from slidably reciprocating at desktop in operation.
In this device, it should be pointed out that the arrangement area of lenslet 6 should be less than the base area of large lens 7.Large lens 7 only have one, the plastics or the glass material that generally adopt refractive index to be less than 2.0.And lenslet 6 can be one, with single, realize white light or monochromatic light hot spot effect, while only adopting a lenslet 6, LED light source 4 should adopt single large chip; Lenslet 6 also can be many, the plastics or the glass material that generally adopt refractive index to be less than 2.0, and while adopting many lenslets 6, LED light source should adopt single chips.Thereby realize RGB mixed light, dazzle the combination of coloured silk and many light and shades, reach various Bright folding effect, as clover, bunge bedstraw herb, plum blossom, sunflower flower texts.LED light source 4 adopts welding manner to be fixed on pedestal 1 bottom, this device also has good applicability, can regulate the distance between LED light source 4 and lenslet 6 according to installation environment and personal like, thereby regulate size and the shape of Bright folding, can meet all kinds of crowds' hobby and demand.
With respect to prior art, compound lens of the present utility model can be realized various symmetries and asymmetric hot spot Overlay, can meet various indoor environment lighting requirements, and the utility model simple in structure, be easy to install, production cost is lower.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here cannot give all embodiments exhaustive.Every still row in protection domain of the present utility model of apparent variation that the technical solution of the utility model amplifies out or change that belong to.
