Types of LED Street Light Housing

Aluminum housing

Widely regarded as the industry standard, aluminum housing offers an optimal balance of lightweight construction and superior thermal conductivity.

PC (polycarbonate) housing

Made from high-impact polycarbonate, this housing type is known for its optical clarity and resilience against physical damage.

Steel housing

Available in galvanized or stainless steel variants, this robust housing is engineered for maximum durability and structural integrity.

Plastic housing (ABS/ASA)

Constructed from engineering-grade thermoplastics like ABS (Acrylonitrile Butadiene Styrene) or ASA (Acrylonitrile Styrene Acrylate), these housings offer design versatility and aesthetic appeal.

Smart housing

Next-generation housings designed with integrated sensors, communication modules, and IoT compatibility for intelligent street lighting networks.

Modular housing

Designed with separate, interchangeable compartments for LEDs, drivers, optics, and power supplies to simplify servicing and upgrades.

Benefits of LED Street Light Housing

Efficient heat dissipation for longer lifespan

LED street light generate heat during operation. When installed directly on wood, plastic, or other low-conductivity surfaces, heat can accumulate, leading to accelerated aging of LED chips.
Light housing have excellent thermal conductivity, efficiently absorbing and dissipating heat, which helps keep the LED street light running stably and extends their service life.

Improved light quality and aesthetics

When used with a diffuser cover (PC cover), aluminum channels can soften the light, eliminate the LED dot effect, and create continuous, even light.
In commercial spaces or home decor, this seamless linear lighting effect creates a sophisticated and visually pleasing ambiance.

Protection against dust and physical damage

The housing and cover form a protective housing that prevents dust, moisture, or accidental contact from damaging the LED street light. This makes light housing ideal for kitchens, cabinets, display cases, and other environments.
