The advantages and working principle of solar street light manufacturers:
1、 System composition
Solar street light system consists of photovoltaic solar panels, solar street light head, intelligent controller (light control, timer and controller)
2、 Working Principle
The working principle of solar street light is that the sunlight shines on the photovoltaic solar panel during the day, realizing the photovoltaic effect, converting light energy into electricity, and storing the current in the solar cell through the charge and discharge controller. When the lighting gradually decreases at night, the open circuit voltage of the solar panel will also decrease. When the charge/discharge solar controller detects that it is lower than the set voltage value, the battery discharges to the light head to illuminate. After the battery discharge time reaches the set value of the controller, the charge/discharge controller acts and the battery discharge ends. The main function of the charge/discharge controller is to protect the battery and make it work for a long time!
1. Solar street lights use solar photovoltaic cells to provide electricity. Solar energy as a new green energy, "inexhaustible, inexhaustible". Make full use of solar energy resources to alleviate the shortage of conventional energy has positive significance.
2, solar street light installation cost is low, simple and convenient installation. Unlike traditional street lights, which require a lot of foundation works such as laying cables, it only needs to fix a base, and all wiring and control parts are placed inside the light frame to form a small whole, which greatly saves manpower and material resources for installation and improves work efficiency.
3, solar street light single unit operation and maintenance costs are low. For the solar power used in solar street lights, except for a small portion of the electricity cost when converted to municipal power on rainy days, the operating cost is almost zero. The operation of the whole system is automatically controlled, without human intervention, almost no maintenance costs.
1. Look at the brightness of the light
Generally speaking, the brightness of high-power LEDs will be much brighter than low-power LEDs, and the price will be much more expensive.
2. Look at the anti-static ability of the lamps
Led anti-static ability, long service life. In general, anti-static voltage greater than 700V led can be used for led lighting.
3. Understand the leakage current of lamps and lanterns
LED is a one-way conductive luminous body. If there is a reverse current, it is called leakage. Led with high leakage current has a short service life and relatively low price.
4. Chip used to identify LED lights
LED light-emitting body for the chip. Different chips are usually good quality and expensive. Chips are imported from abroad.
5. Look at the light-emitting angle of the light
LEDs for different purposes have different light-emitting angles. According to different needs, it is very important to choose the right application to buy the lamps. Therefore, you should know the application site you are buying.
6. Know the wavelength of the light
The same wavelength of LED color is the same, the relative price is relatively high. We should realize that there is no LED beam splitting
It is difficult for color splitter manufacturers to produce pure color products, so you must choose the products produced by reputable manufacturers.
7. Understanding the colloid of the lamp
The colloid of ordinary LEDs is usually epoxy resin. LEDs with UV protection and fire retardants are expensive. High-quality outdoor LED lighting should be anti-UV and fireproof.
8. Know the lamp heat sink
Heat sink can see the appearance of the luminaire. If the exterior or interior of the luminaire is made of aluminum, the thermal effect of the luminaire can be solved, thus better extending the life of the luminaire, and the temperature plays a key role in the life of the LED beads.
