Embodiment Construction

[0007] The selection of super bright LED lights is based on small 1 / 2 angle, so that the light is strong enough to meet the long-distance illumination. The angle of the assembled LEDs also needs to form the light into a rectangle of 30 to 40 meters as well. During operation, the angle of the LED at the center of the assembled electronic lamp is bent, the angle of the edge is not bent, and the light line is perpendicular to the ground.

Abstract

The light from a prior high voltage sodium lamp, a prior LED street lamp and a prior energy-saving fluorescent lamp irradiates a road and forms a circular area or an elliptical area with certain radii, while the irradiation area at an amount of occasions such as a footway, a bridge, etc., is of a strip shape (rectangle), so that a large amount of flabellate irradiation areas are lost. The invention provides an energy-saving LED street lamp with a rectangle irradiation area, and aims to solve the prior flabellate irradiation loss. The energy-saving LED street lamp with the rectangle irradiation area can set the angle of the particulate LED focusing integrator irradiation angle or the required irradiation area, the light emitted by the street lamp is in a rectangle shape, thereby saving the light energy to the greatest extent and further saving the electric energy.

Description

[0001] Applicable fields: [0002] The invention relates to the field of municipal lighting street lamps and lighting. Background technique: [0003] Existing high-pressure sodium lamps, LED street lamps, and fluorescent energy-saving lamps in use all have a circular area or an elliptical area with a certain radius of light on the road surface, while sidewalks, bridges and other places have considerable occasions where the illuminated area is elongated (rectangular) ) Therefore, a large amount of fan-shaped lighting area is lost. However, it has not been seen that the lighting area of ​​street lamps is rectangular. Any road surface is strip-shaped, and the light emitted by the lamps at night is also connected to each other in a rectangle, which reduces the shadow formed by circles and reduces the fan loss. Invention content: [0004] The high-energy-saving LED street lamp with rectangular illumination area of ​​the present invention solves the above-mentioned conventional f...
