LED electronic display board
Structure and body for heat radiation
With an aluminum-made body and the patented technology applied structure, the products have a heat-radiation structure and cooling system for the heat generated from the lamp chambers.
IP67 level water-proof, moisture-proof, and dust-proof
A sealing technology is applied to maintain the IP67 level longer for the protection of the lamps and control parts. Aconverter is installed in a converter room, which is combined into or separated from the street lighting device, forwater-proofing and dust-proofing capabilities.
Protector
Flattened, tempered transparent glass with heat-proofing quarantees superiority in transmittance, performance and impact strength, and also provides safety.
