As shown in Figure 1, the utility model is mainly shown as Fig. 2 by great power LED wafer 1(structure), aluminum-based circuit board 2, shelled peanut lens 3, vaporific granular pattern lens 4, milky pvc pipe shell 5, draw-in groove 6 form; Great power LED wafer 1 directly pastes and is welded in the aluminum-based circuit board 2 that is printed with conducting wire, shelled peanut lens 3 are fastened on great power LED wafer 1, and be fixed together by the plastics joint pin 7 on shelled peanut lens as shown in Figure 3 and installing hole and aluminum-based circuit board 2 in aluminum-based circuit board 2, great power LED wafer 1 and shelled peanut lens 3 are all arranged according to duplicate rows W type.Aluminum-based circuit board 2 fits together by the draw-in groove 6 on shell with the milky pvc pipe shell 5 of vaporific granular pattern lens 4 with inwall.
Described technical scheme is as follows:
First spot light is carried out the expansion of face, secondly on the basis of face expansion, carry out the processing of light mildness.
In order better to realize light diffuse reflection of the present invention, can also comprise following technical scheme:
With the irregular arrangement between the as far as possible little volume of lens and lens, combine with shell and form the milky pvc pipe shell of semi-sphere type.
In order better to realize the soft row of light, also comprise following technical scheme:
Adopt reflective aluminum base circuit board and milky pvc pipe shell to carry out multiple reflections and refraction to light.
In order better to realize illumination range expansion of the present invention, can also comprise following technical scheme:
According to the extended attribute of shelled peanut lens, adopt the symmetrical W type of duplicate rows arrangement mode.
Operation principle of the present invention: adopt the shelled peanut lens that are arranged on single great power LED wafer outside are arranged according to W type, the direct projection light of LED is by shelled peanut lens, expand the angle of scattering of light, scattered light projects through multi-angle, multipath the semi-circular milky pvc pipe shell inwall being made up of many smoke-type granular pattern lens again, send soft light to space by unrestrained transmitting, thereby reach adopt double layer lens direct projection light is spread and irreflexive principle, the carrying out of science the object of secondary optical design.
