COB and SMD LED lights are two types of LED lights available, which are the two primary sources of light these days. Both of these components create high-quality illumination and have a lengthy life expectancy, as well as the highest efficiency to date.
Why COB? --Background LED(light emitting diode) is new technology with advantage of saving energy and very long lifespan. But all LED lightsource can not be faultless especially SMD, HP, flux LED etc. Compare to traditional lighting such as fluorescent lamp, as it is super bright in a s...
所以COB灯条的芯片散热速度比灯珠型灯带来的快,随之COB灯带的光衰更小,寿命更长; ③COB灯条的发光面发光角度可达到180°。 ①Due to the structural characteristics of the COB light strip, the light-emitting surface is a linear colloid; while the ordinary lamp bead type light strip, its structure is ...
COB technology: COB technology is a technology that packages LED lamp beads directly on the PCB board. This technology can improve the brightness and reliability of LED lamp beads, while simplifying the production process and reducing costs. Small pitch LED: Small pitch LED refers to the distance...
“COB” is an abbreviation. What does it mean? A. Close of business. B. Change of business. C. Confirmation of business. D. Cancel of business. 相关知识点: 试题来源: 解析 A。“COB”是“Close of business”的缩写,意思是“营业结束”。选项 B“Change of business”是“业务变更”;选项 C...
Light-Emitting Diode (LED): Function: Converts electrical energy into light energy when forward biased. Operation: When a forward voltage is applied across the LED, it allows current to flow, causing electrons to recombine with electron holes in the semiconductor material, emitting photons (light)...

What is LED? The term LED stands for light emitting diode. It is a type of semiconductor that produces light through the passage of an electric current through the device. When the electron particles carrying the current combine with the material in the semiconductor, known as electron holes, ...
Earth is probably still the world's commonest building material. The word cob comes from an old English root meaning a lump or rounded mass. Cob building uses hands and feet to form lumps of earth mixed with sand and straw, a sensory and aesthetic experience similar to sculpting with clay...
