China All in one Solar Powered Led Street Light System composition
The China solar Powered street light system can guarantee normal work for more than 15 days in rainy weather! Its system is composed of LED light source (including driver), solar panel, battery (including battery incubator), solar street light controller, street light pole (including foundation) and auxiliary materials and wires 
Solar cell components generally use monocrystalline silicon or polycrystalline silicon solar cell components; LED lamp holders generally use high-power LED light sources; controllers are generally placed in the poles, with light control, time control, overcharge and overdischarge protection, and reverse connection protection. Advanced controllers are also equipped with functions of adjusting the lighting time in seasons, half-power functions, intelligent charging and discharging functions, etc.; batteries are generally placed underground or there will be special battery incubators, which can use valve-regulated lead-acid batteries, gel batteries, Iron-aluminum batteries or lithium batteries, etc. The solar lamps work fully automatically and do not need to dig trenches for wiring, but the light poles need to be installed on the embedded parts (concrete base).

LED light source
1. High luminous efficiency, low power consumption, long service life and low working temperature.
2. Strong safety and reliability.
3. The reaction speed is fast, the unit volume is small, and it is green and environmentally friendly.
4. Under the same brightness, the power consumption is one-tenth of that of incandescent lamps and one-third of that of fluorescent lamps, but the life span is 50 times that of incandescent lamps and 20 times that of fluorescent lamps, after incandescent lamps, fluorescent lamps, and gas discharge lamps. The fourth generation of lighting products.
5. The advent of a single high-power super-brightness LED makes it possible for the LED application field to cross the high-efficiency lighting source market. It will be one of the greatest inventions of mankind after Edison invented the incandescent lamp. 
Battery pack bracket
1) Angle design
In order to allow solar cell modules to receive as much solar radiant energy as possible in a year, we have to choose an optimal inclination angle for solar cell modules.
The discussion on the optimal inclination angle of solar cell modules is determined by different regions when they are used in different regions.
2) Wind-resistant design
In the solar street light system, a structural issue that requires great attention is the design of wind resistance. The wind resistance design is mainly divided into two parts, one is the wind resistance design of the battery module bracket, and the other is the wind resistance design of the light pole. Let's analyze the above two pieces separately.
⑴Wind-resistant design of solar cell module bracket
According to the technical parameter data of the battery module manufacturer, the upwind pressure that the solar battery module can withstand is 2700Pa. If the wind resistance coefficient is selected as 27m/s (equivalent to a tenth typhoon), according to the non-viscous fluid mechanics, the wind pressure on the battery module is only 365Pa. Therefore, the component itself can withstand the wind speed of 27m/s without being damaged. Therefore, the key consideration in the design is the connection between the battery assembly bracket and the light pole.
In the design of the street lamp system, the connection design of the battery assembly bracket and the lamp pole uses a bolt pole to fix the connection.
⑵ Wind-resistant design of street lamp pole
The parameters of street lights are as follows:
Battery panel inclination A = 16o pole height = 5m
The design selects the welding seam width at the bottom of the light pole δ = 4mm, the outer diameter of the bottom of the light pole = 168mm
