With many old street lights exiting the shopping malls, solar intelligent street lights have become the mainstream street light choice product. Solar intelligent street light is mainly composed of solar cell module, high power maintenance-free battery, controller, LED light source and light body. Vertical power supply system is selected in the equipment, no buried cable, active charging, active switching light source, simple structure, no manual operation, safe and reliable operation and long service life. With safety, energy saving, environmental protection, practical, efficient, simple equipment and other characteristics. Suitable for municipal construction, parks, scenic spots, families, villas, communities, business decoration and other places that need lighting and phenomenon.
The sunlight irradiates the solar module during the day, so that the solar module produces a certain high and low DC voltage, converts the light energy into electrical energy, and then transmits it to the controller. Through the intelligent controller's overcharge maintenance, the electrical energy from the solar module is transferred to the battery for storage. At night, as the solar module cannot receive light energy, the intelligent controller actively turns on the control equipment, and the battery supplies power to the LED light source through the over-discharge maintenance equipment of the intelligent controller, so that the LED light source can be used for lighting; at dawn, the solar module receives light energy, and the intelligent controller actively converts to charging mode.
Solar controller is the core component of solar intelligent street light, in the application of light control, time control, charging, discharging and other functions, should adhere to the monotonic, internal planning and programmed input, not arbitrarily affect the button. If there are defects, we must have professional operation. Solar controller using low-frequency PWM half-bridge expansion of the main circuit to supplement the voltage loss of the charging circuit than the use of diode anti-reverse charging circuit is reduced by more than half, charging power of 3 % - 6% higher than the non-PWM, increasing the power consumption time; forward charging, normal balanced charging.
Solar street light circuit board is a long-life component in solar intelligent street light, which can be used for 35 years. If it does not rain for many days, a large amount of dust will fall onto the panel surface and affect power generation. If necessary, manual cleaning should be carried out. The direction of the solar panel should be due south. If there is shaking, it should be cleaned in time.
LED light source has a long service life, and the general bad rate is very low. Use 2-3 years, all light sources should be cleaned once, so as not to block the electricity with dirt and reduce the brightness of the lamps. LED light source is as follows
(1)It consists of single piece of power not less than 0.069w for outdoor light with 5mm diameter and 1.16w high power LED light beads for solar intelligent street light.
(2)Modular planning concept, scientific heat dissipation structure planning and high quality thermal conductivity data to ensure timely heat dissipation and high conversion power of LED, which can be used continuously for 50,000 hours.
(3) LED chip luminous efficacy 100m/W, super bright lighting.
(4) LED light source color temperature 4500-5500k, color rendering index ≥ 65.
