In order to protect the life of solar street lamps, many users are concerned about the service life when purchasing LED Street Light. The following OSRAM LED Street Light Supplier will let you know the four factors that really affect LED street lighting.
1. Illumination light source: Different illumination sources have different service life, low-pressure sodium lamp, low-voltage electrodeless lamp, LED lamp, low-voltage fluorescent lamp and other kinds of light sources. LED lamps are mainly used in LED Street Light. The main reason is that the quality of life is 50,000 hours. In theory, 10 hours of lighting per day can be used for more than 10 years. So installing LED Street Light to pick a good light source is the main key.
2. LED Street Light controller: The controller not only controls, monitors and maintains the working condition of the photovoltaic module, battery and load, but also controls the battery together to ensure the working condition of the battery, and directly maintains the load of the solar street lamp. It provides a useful and relatively stable working environment, especially in critical conditions such as lack of battery power or undervoltage operation. A high-precision, stable controller will play a key role. For example, sometimes LED street lighting will flash and flicker. This fault is mainly a problem with the controller.
3. Battery: Select a battery with stable performance. And the battery should be installed tightly during the construction process, beware of accidental elements such as water ingress. Otherwise it will directly affect the service life of solar street lights.
4, light source starter: different starter start method is different, the need for different ballasts or drive power lights. This part has a great influence on the light source. Especially LED light sources. Today, constant current source drives are often used. Whether the constant current source is good or not and whether the parameter size is suitable for the light source is very important. Mainly: constant current accuracy, output power, maintenance circuit, parameter setting scale, etc.
