1. Core Features
High efficiency and energy saving:
Compared with traditional high-pressure sodium lamps or metal halide lamps, LED street lamps reduce energy consumption by 50%~70%, and the light efficiency can reach 100~200lm/W, significantly reducing electricity bills.
Long life:
The service life is usually 50,000~100,000 hours (about 10~15 years), reducing the cost of frequent replacement and maintenance.
Environmentally friendly and pollution-free:
It does not contain harmful substances such as mercury and lead, no ultraviolet/infrared radiation, and complies with RoHS standards.
Good color rendering:
The color rendering index (CRI) is ≥70, the light is closer to natural light, and the visual clarity at night is improved.
Intelligent control:
Supports dimming, timer switch, remote monitoring (such as with NB-IoT, LoRa and other Internet of Things technologies), and adapts to the needs of smart cities.
2. Main structural components
LED light source:
Use high-brightness LED chips (such as COB or SMD packaging), single or multiple combinations to ensure uniform lighting.
Cooling system:
Aluminum alloy heat sink fins or heat pipe design, effectively reduce junction temperature and extend life.
Optical lens:
Secondary light distribution design (such as bat wing light distribution) to avoid glare and improve road illumination uniformity.
Drive power supply:
Constant current drive, wide voltage input (AC85V-265V), with overvoltage, overcurrent and lightning protection.
Shell material:
Die-cast aluminum or high-strength polycarbonate (PC), protection level IP65 or above, corrosion-resistant, dustproof and waterproof.
3. Common types
Conventional LED street lights:
Power 30W~400W, suitable for main roads, branches, etc., color temperature optional 3000K (warm white) ~ 6000K (white).
Solar LED street lights:
Integrated photovoltaic panels + batteries, off-grid power supply, suitable for areas without power grid.
Modular street lights:
Modular design, easy to repair or upgrade locally, reducing maintenance costs.
Smart street lights:
Integrate environmental sensors, cameras, Wi-Fi, etc. to achieve multi-functional smart management.
