Some kinds of LED lights are dimmable. Make sure to Check out packaging to determine In the event the bulb is suitable with dimmer switches.
It is just a Exclusive type of diode that converts electrical Power into mild energy. Not like an incandescent bulb, it does not get incredibly hot, for that reason It is actually an Power-productive light source. It is out there in each and every size, shape and color.
LEDs are quite delicate units and the quantity of present-day flowing through an LED is critical. Also, the brightness of an LED depends upon the quantity of existing drawn from the LED.
Aug 28, 2012 We are sending an incredible significant HELLO to the many WONDERful college students in Mrs. Foster's course! Many thanks for submitting this sort of a fantastic comment about LED lights today!! LED lights are almost everywhere, and they provide light-weight in a lot of the electronics you employ every single day (including your Television, alarm clock and in some cases your computer screen).

If you have checked the two issues higher than and also your LED is still not illuminating it's now time to interchange your LED.
便於聚焦，因發光體積細小，而易於以透鏡等方式達致所需集散程度，藉改變其封裝外形，其發光角度由大角度散射至細角度聚焦都可以達成。

每枚發光二極管因生產技術問題都會在特性（亮度、顏色、偏壓…等）上有一定差異，即使是同一批次的發光二極管差異也不少。
發光二極管只能夠往一個方向導通（通電），叫作正向偏置；當電流流過時，電子與電洞（电子空穴）在其內复合而發出單色光，這叫“電致發光效應”；而光線的波長、顏色跟其所採用的半導體物料種類與故意摻入的元素雜質有關。發光二極管具有效率高、壽命長、不易破損、反應速度快、可靠性高等傳統光源不及的優點。
