Problems solved by technology

[0003] At present, the PC lens of street lamps designed on the market has a spot length of about 4 times the pole height irradiated on the road, that is, the maximum pole distance can only be 4 times the pole height, but the current pole distance of street lamps in many countries However, it is set to 4.5 times the height of the pole, and the existing PC lens cannot be used for this kind of road

Embodiment Construction

[0023] The present invention will be described in detail below in combination with specific embodiments.

[0024] combine figure 1 and figure 2 Shown is a cross-sectional view and a schematic perspective view of the PC lens of the present invention. The PC lens comprises a housing 1 and a cavity 2 shaped as a quarter ellipsoid in the housing 1, the housing 1 consists of a concave upper curved surface 11, an outwardly convex left curved surface 12, and an outwardly convex left curved surface 12. The convex right curved surface 13, the front curved surface 14 and the flat rear plane 15 are formed, and the left curved surface 12 and the right curved surface 13 are symmetrical, and the widths of the front curved surface 14 and the rear plane 15 are different. In an embodiment, the width of the rear plane 15 is greater than the width of the front curve 14 .

[0025] Wherein, the upper curved surface 11 , the left curved surface 12 , the right curved surface 13 and the front cur...

Abstract

The invention discloses a PC lens comprising a shell and a cavity. The cavity is arranged in the shell and in a shape of a quarter of an ellipsoid, the shell is composed of a recessed upper curved surface, a left curved surface, a right curved surface, a front curved surface and a flat rear plane, the left curved surface, the right curved surface and the front curved surface protrude outwards, the left curved surface and the right curved surface are symmetrical, and the front curved surface and the rear plane are different in width. Since the PC lens, a dot matrix PC lens module and a LED street lamp are provided with the PC lens shell with the outer surface in left-right symmetry and up-down asymmetry and the LED street lamp is eccentric, illumination utilization rate and uniformity of the street lamp can be improved, and an illuminating range is enlarged so as to increase pole span and decrease pole number.

Description

technical field [0001] The invention relates to a PC lens module of a dot-matrix LED street lamp. Background technique [0002] At present, the PC lenses of the dot matrix LED street lamps on the market are designed with up-down symmetry and left-right symmetry. Because the light poles are mostly arranged beside the road, not in the middle of the road, only 50% of the light produced by the street lamp using the existing PC lampshade can irradiate the road surface at most. [0003] At present, the PC lens of the street lamp designed on the market has a spot length of about 4 times the height of the pole irradiated on the road, that is, the maximum pole distance can only be 4 times the height of the pole, but the current pole distance of street lamps in many countries However, it is set to 4.5 times the height of the pole, and the existing PC lens cannot be used for this kind of road. Contents of the invention [0004] Due to the above-mentioned problems in the prior art, ...
