After a period of use, the brightness of the LED street lamp will decline, and the declining part is the LED light decline. Any LED street lamp product will produce light attenuation. The light attenuation of LED street lamps refers to the weakening of the light signal during transmission. At present, LED street lamp manufacturers do not make the degree of light failure of street lamp products, high-power LED street lamps also exist light failure. Temperature is directly related to light attenuation, and also related to the chip quality, phosphor, packaging process of LED street lamp head.

There are many reasons for light attenuation in LED circuits. The thermal resistance of LED chip itself, the influence of silver glue, the heat dissipation effect of substrate, colloid and gold wire are related to the light attenuation. Excessive temperature will reduce the service life of electronic products. Some LED street lamp manufacturers are focusing on heat dissipation in their low-cost products. After long-term use, the light attenuation of these LED street lamps will be much higher than that of well-cooled LED lamps.

The way to reduce the attenuation of LED light is to ensure the quality of lamps and the heat dissipation of street lamps. The honeycomb LED street lamp holder independently developed by the company can well meet the heat dissipation requirements of LED street lamps. It uses bionics design, up and down through the hole of the honeycomb cooling structure, not only conducive to heat conduction, but also conducive to air convection, take away excess heat, the service life of lamps and lanterns naturally longer.
