• Impact Resistance and Wear Resistance: The metal housing can withstand accidental impacts, knocks, and friction during installation, use, and daily maintenance, effectively protecting the internal core LED and circuitry. This makes it particularly suitable for applications with strong vibrations and potential impacts, such as mining machinery and heavy equipment.
• Outstanding Temperature Resistance and Heat Dissipation: Metals (such as aluminum alloy, stainless steel) can withstand higher ambient temperatures than engineering plastics, and are not prone to softening, deforming, or aging due to heat.
• Natural Heat Sink: Metal is a good conductor of heat, enabling it to rapidly conduct and dissipate the heat generated by the LED chip during operation into the external environment. This effectively extends the LED's service life and prevents light decay.
