What caused the led light darker?
The darker the LED light is, the more common it is. Summarizing the reasons for the darkening of LED lights is nothing more than the following three points. Driver damage LED lamp beads are required to work at DC low voltage (below 20V), but our usual mains supply is AC high voltage (AC 220V). To...Read more -
Why color temperature LED flash is so popular these days?
It is well known that taking pictures at close range when the light is particularly dark, no matter how powerful the low light and dark light photographing ability, no flash can be shot, including the SLR. So on the phone, it has spawned the application of LED flash. However, due to the limitatio...Read more -
Which five main factors will affect the span life of LED lights?
If you use a light source for a long time, you will get huge economic benefits and reduce your carbon footprint. Depending on the system design, luminous flux reduction is a normal process, but can be ignored. When the luminous flux is reduced very slowly, the system will remain in good condition...Read more -

LED driver is powerful
As the core component of LED lights, LED power supply is like the heart of LED. The quality of LED drive power directly determines the quality of LED lamps. First of all, in the structural design, the outdoor LED drive power supply must have strict waterproof function; otherwise, it can’t withsta...Read more -
LED driver has three main technical solutions
1. RC Buck: simple embodiment, the device small, low cost, is not constant. Mainly used 3W and below LED lamp configuration, and there is a danger of leakage caused by breakdown of the lamp board, so the structural shell of the lamp body must be insulated; 2. Non-isolated power supply: the cost i...Read more -
How to judge the quality of LED lights
Light is the only light source available indoors at night. In daily household use, the impact of stroboscopic light sources on people, especially the elderly, children, etc. is obvious. Whether studying in the study, reading, or resting in the bedroom, inappropriate light sources not only reduce ...Read more -
Analysis of technical problems of led filament lamp
1. Small size, heat dissipation and light decay are big problems Lightman believes that to improve the filament structure of LED filament lamps, LED filament lamps are currently filled with inert gas for radiation heat dissipation, and there is a big gap between the actual application and the des...Read more -
Five ways to choose integrated ceiling led panel light
1: Look at the power factor of the overall lighting The low power factor indicates that the driving power supply circuit used is not well designed, which greatly reduces the service life of the lighting. How to detect? —— Power factor meter generally exports LED panel lamp power factor requiremen...Read more -
Lightman led panel lights design and production process
