Led Downlight Housing

A polycarbonate panel light housing is a durable enclosure made of polycarbonate, a strong, lightweight plastic often used in lighting due to its:

• High impact resistance (250x stronger than glass)

• Transparency (up to 90% light transmission)

• UV resistance (when coated)

• Flame retardant properties (with appropriate additives)

🛠️ Common Applications

• Industrial and commercial lighting – High-bay or low-bay lighting in warehouses

• Outdoor lighting – Street lights, parking garages, or canopy lights

• LED panel lights – Office ceilings, backlit signs, or architectural lighting

• Vapor-tight or waterproof fixtures – Used in damp or wet environments

🧩 Components of the Housing

A typical polycarbonate panel light housing includes:

• Front diffuser panel: Flat or curved polycarbonate sheet that diffuses light.

• Back plate or fixture frame: Often aluminum or coated steel for thermal management.

• Seals/Gaskets: Ensure waterproofing and dustproofing (IP65, IP67 ratings).

• Mounting brackets: For ceiling, wall, or pendant installations.

• LED modules and driver (inside): The actual lighting components.

✅ Benefits

• Impact resistant – Ideal for vandal-prone or harsh environments.

• Lightweight – Easier to install than glass or metal housings.

• Thermal stability – Performs well in extreme temps with proper design.

• Diffusion options – Clear, frosted, or prismatic finishes for various lighting effects.

📌 Things to Consider When Choosing One

• Size and dimensions of the panel

• Light output and type of LED/fluorescent used

• IP rating (if outdoor or in harsh environments)

• UV protection (if exposed to sunlight)

• Mounting style (surface, suspended, recessed)
