How hot is the LED bulb?

It feels hot to the touch, but not as hot as CFL bulbs, halogen lamps and incandescent lamps. LED bulbs are one of the latest and most efficient lumination technology. Compared with the hot filament used in the previous generation of bulbs, the operating temperature of the light produced by high-power lighting LEDs is much lower.… Read More

With the advancement of science and technology, the depth of detection of the ocean is getting larger and larger, and deep-sea operations are often affected due to insufficient solar light, or even because visibility is too low to perform. However, the general underwater lighting incandescent lamp can only withstand about 10 meters of water pressure, and because the structure of the incandescent lamp is not conducive to heat dissipation and waterproof, short life, and safety performance problems.… Read More

Definition of COB

COB is the chip on board, which is to attach the bare chip to the interconnect substrate with conductive or non-conductive glue, and then wire bonding to achieve its electrical connection. There are three package types: long, square, and round.

COB production process

The COB LED surface light source firstly covers the silicon wafer placement point with a thermally conductive epoxy (generally an epoxy resin doped with silver particles) on the surface of the substrate, and then directly places the silicon wafer on the surface of the substrate, and heat-treats the silicon wafer to be firmly fixed on the substrate.… Read More

The importance of outdoor sports lighting:

Lighting design is a rigorous scientific practice process. When we implement ideas and themes, we need strong technical support, analytical research, and scientific demonstration. This includes logic, optimization, details, optics, materials science, organization and construction, energy saving and consumption reduction, intelligent control, and so on. All of these form the backbone of the design and are indispensable.… Read More
