No-glare LED (light-emitting diode) streetlamp

Abstract

The invention discloses a no-glare LED (light-emitting diode) streetlamp, which comprises an aluminum shell and a transparent lamp shade arranged at an opening of the front end of the aluminum shell. A substrate, an LED lamp and a cooling module group which are fixed at the positive face and the negative face of the substrate respectively are arranged in the aluminum shell; a driving power supply module is arranged on the cooling module group; a lens is arranged outside the LED lamp; and the lens comprises a composite curved surface which is made from a plurality of asymmetric bulges. When the LED lamp shines, the shone light forms different rectangular uniform light spots at the left and the right of the LED streetlamp after the light is subjected to multiple reflection and multiple refraction in the composite curved surface; when an automobile passes through under the LED streetlamp, light spots near the automobile are smaller, light rays entering the automobile from a front windshield are very few, and thus, the glare is maximally avoided; and light spots far away from the automobile are bigger, a visual range for a driver is great, and then, the driving safety is improved.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a glare-free LED street lamp. Background technique [0002] In recent years, LED lights have achieved rapid development and are gradually entering the field of general lighting. Compared with traditional incandescent tungsten bulbs and fluorescent lamps, LED lamps have the advantages of small size, low calorific value, and low power consumption, and can be started at low voltage and low current, with fast response speed, high-frequency operation, and long service life. Therefore, it is called "green lighting source". [0003] The LED lamp assembly can be used as different lighting lamps, such as street lamps, tunnel lamps, etc. The current LED street lamps emit symmetrical light spots to the left and right sides of the road, such as figure 1 As shown in the light spots A and B, when the driver passes under the street lamp at night, on the one hand, the light spot A that is closer to the c...

AI Technical Summary

Problems solved by technology

The current LED street lamps emit symmetrical light spots to the left and right sides of the road, such as figure 1 As shown in the light spots A and B, when the driver passes under the street lamp at night, on the one hand, the light spot A that is closer to the car is too large, and the light is easy to enter the car through the front windshield, causing dazzling; The far B spot is far from enough, and the driver's visual range is greatly limited, which brings safety hazards to driving
