Historie pouličních světel

Co je pouliční osvětlení?

Nedostatek přirozeného světla v noci v městském prostředí byl vždy problém. Od základních nepříjemností, které lidé nevidí, kam jdou, k větší šanci na útok nebo přepadení v noci. Protože problém tu byl od doby, kdy lidé začali žít společně, historie pouličního osvětlení je možná delší, než si myslíme.

 

Pouliční osvětlení nebo pouliční lampa je vyvýšený zdroj světla, který je často namontován na sloupu nebo sloupu lampy buď na straně silnice, nebo ve střední části, nebo zavěšen na drátu nad vozovkou, aby poskytoval osvětlení.… Read More

Hoeveel watt LED-lampen kunnen 1000W metaalhalidelampen vervangen

Wat is een metaal halogenide lamp?

Een metaal halogenide lamp is een elektrische lamp die licht produceert door een elektrische boog door een gasvormig mengsel van verdampt kwik en metaalhalogeniden (verbindingen van metalen met broom of jodium). Het is een soort gasontladingslamp met hoge intensiteit (HID).

De lampen bestaan uit een kleine gesmolten kwarts of keramische boogbuis die de gassen en de boog bevat, ingesloten in een grotere glazen bol die een coating heeft om het geproduceerde ultraviolette licht uit te filteren.… Read More

Expansion of the main, auxiliary, and backlight 3-point lighting modes

TV cold light diffused light fixture is a large area diffused light source, which is very convenient for lighting. It completes the art of lighting modeling by selecting and configuring the power of the lamp, adjusting the distance and height between the lamp and the object. Because the cold light lamp can form its own system, it can also be coordinated with other lamps with the same color temperature.… Read More

Что такое светодиоды и история светодиодов

Что такое светодиод?

Проще говоря, светоизлучающий диод (LED) – это полупроводниковое устройство, которое излучает свет, когда через него проходит электрический ток. Свет образуется, когда частицы, переносящие ток (известные как электроны и дырки), объединяются в полупроводниковом материале.

 

Поскольку свет генерируется внутри твердого полупроводникового материала, светодиоды описываются как твердотельные устройства. Термин твердотельное освещение, который также включает органические светодиоды (OLED), отличает эту технологию освещения от других источников, в которых используются нагретые нити накала (лампы накаливания и вольфрамовые галогенные лампы) или газоразрядные (люминесцентные лампы).… Read More

What is Surge

Classification of surge protectors

According to working principle

⒈Switch type: Its working principle is that it presents high impedance when there is no instantaneous overvoltage, but once it responds to the lightning instantaneous overvoltage, its impedance suddenly changes to a low value, allowing lightning current to pass. When used as such devices, the devices include: discharge gap, gas discharge tube, thyristor, etc.… Read More
