Traditional fluorescent lamps use mercury vapor as the light source, which has poor color reproduction and contains mercury vapor that is harmful to the human body. Nowadays, with the development of science and technology, LED back lights are gradually replaced. The LED backlight has good color reproduction, long life, no mercury, is conducive to environmental protection, and can work at low voltage, with fast response speed and convenient control.

Lenses are widely used, and many things in life use the principle of lenses, such as glasses, cameras, telescopes and so on. The LED lens module ingeniously and closely links the lens with the LED, which enhances the efficiency of light. To change the optical system of the light field distribution of the LED, it can be changed by using different lenses. Truly improve the role of light, powerful in life

LED lens modules are mainly used in commercial advertisements, such as LED screens, because they can display slogans prominently at night or during the day, and can have a variety of changes, so they are widely used in commercial advertisements, etc. . So, how does it work? And what kind of characteristics? How LED Lens Modules Work The LED lens module is

We all know that the quality and performance of LED backlights are very good, but if there is a fault, how should we repair it? In fact, we can also carry out simple maintenance and treatment on it ourselves. When we master his repair method, we can avoid a lot of trouble, and at the same time, we can make ourselves convenient. If the LED backlight fails, both

Some light-emitting LED lens module products, especially the light-emitting LED lens modules on flashlights, have different beam colors. It's not that some hidden mechanism is used to make them look pretty, different light colors have different applications. Below is a brief introduction to the most common colors and their practical uses. White light has perfect color properties, but it impairs low-light-adapted vision
