The control system is like a conductor, which allows each LED lamp bead to accurately emit the required light by finely regulating the current. While the LED emits light, it also silently converts most of the electrical energy into heat energy. This is not only a waste of energy, but ...
1. General lighting: this is also known as ambient lighting, it is uniform and enables the different activities to be carried out in a room to be correctly undertaken, since it usually lights up every corner. It usually consists of one or more spotlights or ceiling lamps that work with s...
解析 A。LED 是 Light Emitting Diode 的缩写,意为“发光二极管”。选项 B“Lighting Emitting Diode”意为“照明发光二极管”,不是常见缩写;选项 C“Luminous Emitting Diode”意为“发光的二极管”,表述不准确;选项 D“Luminescent Emitting Diode”意为“发光的二极管”,表述不准确。
In star concerts, the stage usually uses dazzling lighting effects, so it is necessary to choose a high-brightness and contrast LED display to ensure that the picture is still clearly visible under strong light and can complement each other with the stage lights. ...
It does not look like it like it has any shielding but I want to get other's thoughts on that. Anyone know what this style of light is, and does the LED 40 on it tell anything about how bright it is? But note my biggest question is whether I am correct that there is not shieldi...
Computer dictionary definition of what LED (Light-Emitting Diode) means, including related links, information, and terms.
So, when you are considering adding an LED display screen to your shopping mall, don’t forget to ask yourself first: What kind of screen does my shopping mall need? What kind of design can perfectly integrate with my shopping mall?
