Energy-saving and environment-friendly LED illuminating lamp for expressway

Abstract

The invention discloses an energy-saving and environment-friendly LED illuminating lamp for an expressway, and relates to the technical field of highways. The LED illuminating lamp comprises a lamp holder mounted on a lamp bracket, a circuit board mounted on the lamp holder and a mains supply for supplying power to the LED illuminating lamp, a plurality of LED lamp beads are arranged at the bottomof the circuit board, the outer side at the bottom end of the circuit board is covered with a lampshade, the top end of the lampshade is detachably connected to a bottom thread of the lamp holder, and a convex lens is arranged right below the circuit board and is fixedly arranged at the bottom in an inner cavity of the lampshade. According to the utility model, solar energy and commercial power supply are combined into a whole, when solar energy is insufficient, the mains supply supplies power, and when the solar energy is sufficient, solar energy is used for supplying power, and then the solar energy and the mains supply are reasonably converted and utilized, so that the energy-saving and environment-friendly effects are achieved, also the convex lens is arranged right below the LED lampbeads, scattered light emitted by the LED lamp beads can be easily gathered as shown in the figure, and the illumination brightness is further improved.

Description

technical field [0001] The invention relates to the technical field of highways, in particular to an energy-saving and environment-friendly LED lighting lamp for highways. Background technique [0002] LED lighting fixtures are the general term for LED lighting fixtures, which refer to appliances that can transmit light, distribute and change the light distribution of LED light sources, including all parts and components required to fix and protect LED light sources except for LED light sources, as well as connections to power sources The necessary line accessories, with the further maturity of LED technology, LED will achieve more and better development in the field of room lighting design and development.

Problems solved by technology

[0003] Existing LED lights for highways are generally powered by mains power or solar power. When one of them is powered off, the LED lights cannot be used normally; in addition, the existing solar-powered LED lights directly expose the solar panels to The outside world, so dust is easy to adsorb on the solar panel, causing the conversion efficiency of solar energy to be greatly reduced
