We can find the appropriate parameters from optical, electrical, physical structures.
Optical part: display index, strobe index, UGR, color temperature CCT, luminous flux/lumen, illuminance/brightness, luminous angle, luminous effect and so on, are all common parameters we need. When buying LED lamps and china high efficiency led lights, you need to understand these parameters in detail.
Electrical parts: voltage, current, power, conversion efficiency, voltage level, insulation type, voltage current adjustment rate, ripple, power factor, harmonics, overvoltage protection, overload protection, short circuit protection, surge current, leakage current, electromagnetic interference and other parameters.
Physical structure: dimensions, temperature and humidity, material and so on.
LED beads are light sources, light emitting devices, convert electrical energy into light energy, but also heat.
The driving power converts the mains power 220V to the safe and suitable voltage and current of the LED light source.
Aluminum substrate as the carrier of LED lamp bead, fixed lamp bead, LED heat absorption and diffusion into the air.
The lamp shell has three main functions. The first is to spread the LED heat into the air, the second is to protect the internal components of the lamp, and the third is to form a distinct appearance shape and convenient installation structure. Of course, there is also a large portion of the market that does not include a driving power source.
Optical devices make the light emitted by LED light source go through secondary processing, filtering or changing the angle of light to form a certain angle or surface illumination, so that the light is more uniform and softer. Another function is to protect LED light sources.
Tube, bulb, panel lamp, mining lamp, three-guard lamp, street lamp, courtyard lamp, line lamp and so on are all these structures. Although the appearance size and shape are different, their structural composition is the same without exception. Since they have the same structural composition, their evaluation parameters are similar. Below, we'll try to list the parameters that measure their performance.
