A kind of high-power LED street lamp Transparent lamp shade that contains said transparent module contains cover body and is located at its frame and installing hole all around, and cover body is the assembly of the said outstanding sphere of distribution some on plane bottom plate.
Being integral structure or fabricated structure between the said adjacent transparent module, is integral structure or fabricated structure between said transparent module and the frame.
Said array is a rectangular array, said frame and said array coupling, and said frame is provided with reference column.
The beneficial effect of the utility model:
1, the utility model utilizes the lampshade of all-refraction type secondary optical lens design can collect the whole 180 ° light that sends from led chip, and is re-assigned to the zone of appointment.The luminous intensity distribution of free form surface can make the far field angle of LED street lamp light intensity distribute to be batswing tab and distribute, and make the hot spot rectangularity, and the centre of hot spot is more even with the edge, utilizes the rim ray principle, and lens can also realize cutting the light design, the elimination dazzle.
2, the utility model lens and lens module are a kind of designs of secondary optical lens of total refraction type, and these lens can realize that the wing distribution curve flux of very high output optical efficiency, bat distributes and uniform rectangular light spots.Make the LED street lamp produce the rectangular hot spot that just in time covers road, lack what other the local light pollution outside the road were tried one's best.Make and on single lens module, just can accomplish the rectangular output facula of high efficiency, wing far field angle distribution and the realization section light design of bat, and effectively improved light intensity.
3, become very succinct of the structure of whole lamp holder as long as these are accomplished the LED lens module of luminous intensity distributions design, get final product according to same direction combination, simplified arranging that frame for movement, radiating management and the power supply of LED street lamp control.
