Efficient solar street lamp

Abstract

The invention discloses an efficient solar street lamp. The efficient solar street lamp comprises a lamp post and an illumination module, wherein the illumination module comprises an LED lamp and a control circuit board, the LED lamp is connected with the lamp post through a connecting rod, the LED lamp is electrically connected with the control circuit board, a brightness sensor is arranged at the upper part of the lamp post, and the brightness sensor is used for controlling the brightness of the LED lamp; an intelligent charging pile is arranged at the lower segment of the lamp post; the lamp post is further provided with a storage battery, the storage battery is electrically connected with the LED lamp, and the lamp post is further provided with a solar cell panel for charging the storage battery; the solar cell panel comprises a tempered glass layer, a first adhesive layer, a reflecting layer, a second adhesive layer, a battery piece, a third adhesive layer, a backing plate layer and an aluminum alloy layer. According to the efficient solar street lamp, by setting the reflecting layer, the light absorption rate and sensitivity of the solar cell panel are improved, the light scattering rate is reduced, and the photovoltaic conversion efficiency is improved; through the scheme, traditional EVA resin of the first adhesive layer, the second adhesive layer and the third adhesivelayer is modified, so that the ageing resistance and bonding strength of a packaging glue are greatly improved; the LED lamp can be used for automatically sensing the existence of light and automatically turning on and turning off the street lamp according to the intensity of visible light, so that reasonable distribution and utilization of resources are realized.

Description

technical field [0001] The invention relates to the technical field of street lamp lighting, in particular to a high-efficiency solar street lamp. Background technique [0002] As a clean energy source, solar energy has always been the direction of exploration for human beings to make full use of solar energy. Solar street lamps are not affected by power supply, do not consume conventional electric energy, and can be installed on the spot as long as the sun resources are sufficient, so they are widely used and concerned. Solar street lights all use solar cell modules to provide electric energy, and the existing solar street lights have low power conversion efficiency, and the energy-saving effect of street lights is poor. Contents of the invention [0003] In view of the problems existing in the above-mentioned existing solar street lamps, the present invention provides a high-efficiency solar street lamp, which can save energy for street lamp lighting and has high photoel...
