The industrial prospects and focus of led solar street light factory
Solar street light is a new product integrated by the photovoltaic industry and the street light industry. Because it can directly use sunlight for power generation, it has the characteristics of energy saving and power saving, no need to lay cables, and safety and stability. It is now widely used by us to replace traditional Street lights. However, with our extensive promotion and application, LED solar street lamp manufacturers are currently facing a serious quality crisis.
The main components of solar street lights are the following parts
The main function of the solar charge and discharge controller is to protect the battery. The basic functions must have overcharge protection, overdischarge protection, light control, time control, anti-reverse connection, charging trickle protection, undervoltage protection, waterproof protection, etc.
1) Device selection
In the selection of devices, there are currently single-chip microcomputers and comparators. There are many solutions, each with its own characteristics and advantages. The corresponding solutions should be selected according to the needs and characteristics of the customer group, which will not be described in detail here.
2) Surface treatment
This series of products adopts new electrostatic coating technology, mainly FP professional building material coatings, which can meet customers' requirements for product surface color and environmental harmony. At the same time, the products have high self-cleaning properties, strong corrosion resistance, and aging resistance, and are suitable for any Climate environment. The processing technology is designed to be coated on the basis of hot-dip galvanizing, which greatly improves the performance of the product and meets the most stringent requirements of AAMA2605.2005. Other indicators have reached or exceeded the relevant requirements of GB.
3) Charge trickle protection
When the Yijia solar panel is charging the battery, after the battery reaches the peak voltage, if the battery continues to be charged with high voltage, it will easily cause the battery to lose water or run out of control; if the charging is stopped, the battery cannot be saturated. This controller immediately steps down 1V after charging to the peak voltage, and then enters the trickle charge state, ensuring that the battery can be stabilized in a full state, while avoiding water loss or loss of control, similar to cyclic charging of the battery, not only efficient It protects the battery, and also increases the number of charging of the battery, and the service life is longer.
For example, solar street lights in a certain village were installed in less than half a year but all were removed; the failure rate of solar street lights in a town was as high as 50% after a few months of use; in many areas, solar lighting and garbage projects were directly replaced with ordinary city circuit lights; solar street lighting project maintenance Frequent, resulting in waste of manpower, material resources and funds. What causes these quality problems in solar street lights?
Solar street lights are composed of system products, many parts are assembled by pieces, which gives some black-hearted solar street lights wholesale manufacturers a loophole. In order to ensure the low price of the products, some black-hearted manufacturers often cut corners and shoddy materials in the production process, and then bid at low prices, causing the industry to flood low-quality and low-cost garbage projects. There are no professional and technical personnel, and there is no strong management and technical ability. The project construction management can not keep up, and the project quality is not good enough, which makes hidden danger projects and garbage projects rampant.
In this chaotic solar street lamp market, the wholesale quality of solar street lamps can only be guaranteed if the price is guaranteed. Appropriate profits can have appropriate quality assurance. LED solar street lamp manufacturers will not lose money to do business, and low prices must be the starting point to reduce the cost of the product itself. In addition, low prices will also cause no one to answer after-sales. Consumers will face the dual pressures of quality and after-sales after buying inferior products. Regulate the market, customize market reasonable prices, and resist low-price vicious competition.
