The national advocacy and promotion of environmental protection have led to an increasing emphasis on solar energy.
Solar street lights have naturally become popular products in the new generation of lighting. Next, we will briefly understand the structure of solar street lights, which mainly consists of lamp poles, street lamp heads, light sources, solar panels, batteries, and controllers. Below, we will analyze the overall lifespan of solar street lights based on these components.
1. Lighting Source:
Different light sources have different lifespans, with options including low-pressure sodium lamps, low-pressure induction lamps, LED lamps, and low-pressure fluorescent lamps. Currently, sodium lamps, induction lamps, and LEDs are more commonly used.
1. Sodium lamps are inexpensive but have a shorter lifespan.
2. High-quality LED lamps can last around 50,000 hours. Theoretically, if used for 10 hours a day, they can last over 10 years, with a warranty period of generally 2 years, making them a favored light source due to strong government support and promotion.
3. Induction lamps mostly use DC low-frequency induction technology, standing out as a new energy-saving light source with an estimated lifespan of up to 100,000 hours, making them suitable for solar energy systems.
2. Light Source Starter:
Different starting methods require different ballasts or driving power sources for the lamps, which significantly influence the light source, especially for LEDs. Nowadays, a constant current source is generally used for driving. The quality of the constant current source and whether the parameter settings match the light source is very important. Poor matching can directly affect both the lifespan of the light source and the power source; electronic ballasts for low-frequency induction lamps stabilize temperature controls to prevent aging and damage to internal components, ensuring complete lifespan.
3. Solar Controller:
The controller regulates, monitors, and protects the operation of photovoltaic components, batteries, and loads in the solar street light system. It effectively controls the battery operation while indirectly protecting the load (solar street light), providing an effective and relatively stable operating environment, especially during critical states such as insufficient battery power or undervoltage. A highly precise and stable controller plays a key role, with a general warranty period of 2 years.
For example, sometimes solar street lights may flicker. The controller is one potential cause, but not the only one.
4. Battery:
A battery with stable performance should be chosen, and construction must be secure to prevent water intrusion and other unforeseen factors. Otherwise, it may indirectly affect the lifespan of the street light, with a warranty period of 2 years.
5. Solar Panel:
Manufacturers of solar panels currently provide warranties for up to 20 years, which means this is no longer a concern in solar systems.
