Solar LED street lamp with protection function

Abstract

The invention relates to the technical field of solar street lamps, and discloses a solar LED street lamp with a protection function. The solar LED street lamp comprises a lamp post, a protection shell is arranged on the left side of the lamp post, an LED lamp protection device is fixedly connected to the middle of an inner cavity of the protection shell, and a transparent funnel is fixedly connected to the bottom of the LED lamp protection device. According to the solar LED street lamp with the protection function, the LED lamp protection device, a water receiving spherical barrel, an elasticcontraction part and a water outlet and seepage rod are matched, clear rainwater collected on the water receiving spherical barrel is stored in the annular groove, the cooling effect is achieved on the LED core tube located in the LED lamp protection device, meanwhile, when the inner groove of the annular groove is filled with liquid, the liquid in the annular groove can be conveniently replaced,so that the LED core tube is indirectly cooled through the LED lamp protection device, the luminous efficiency intensity of the electrified LED core tube is favorably maintained, the luminous decay speed of the LED core tube is reduced, and the service life of the LED core tube is prolonged.

Description

technical field [0001] The invention relates to the technical field of solar street lamps, in particular to a solar LED street lamp with protection function. Background technique [0002] Solar LED street lights collect energy through photoelectric semiconductor sheets that are directly irradiated by sunlight on the solar panel, and use photoelectric direct conversion to store electric energy, so as to provide energy for street lights made of LED light sources, which are efficient, safe, environmentally friendly and responsive. The unique advantages of fast speed and high color rendering index are of great significance to energy saving of urban lighting. [0003] The LED core tube in the existing solar LED street lamp emits a large amount of heat while emitting light. According to the law of energy conservation, the original stored electric energy is converted into the electric energy and the heat energy emitted by the corresponding LED core tube when it emits light. Theref...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a solar LED street lamp with protective function, which can effectively cool down the LED core tube, improve the service life of the LED core tube, maintain the aesthetics of its outer surface, and maintain the perspective of the light passing through the lamp shell. It solves the problem that the LED core tube in the existing solar LED street lamp emits a large amount of heat while emitting light. According to the law of energy conservation, the original stored electric energy is converted into the corresponding LED core tube when it emits light. Therefore, when the heat energy emitted increases, the luminous efficiency of the LED core tube will decrease with the increase of temperature, which will greatly affect the life and light decay of the LED chip; During the process, the falling raindrops are adsorbed on the outer wall of the lamp housing, which in turn causes the street lamp to diffuse, thereby reducing the intensity of the light penetrating the lamp housing, which is not convenient for illuminating night pedestrians and driving vehicles on the road in the corresponding street lamp area. When the raindrops adhere to the outer wall of the lamp housing, it is easy to condense the dust on the outer wall of the lamp housing. When the raindrops dry up on the outer wall of the lamp housing, it is easy to make the condensed dust form spots, which not only affects the illumination brightness of the street lamp At the same time, the problem that affects the appearance of street lamps
