In a nutshell, LEDs are like tiny lightbulbs. However, LEDs demand a good deal much less power to gentle up by comparison. They're also extra Electrical power efficient, so they don't often get incredibly hot like typical lightbulbs do (Until you might be truly pumping electrical power into them).
a light-weight bulb (= a rounded glass container that is an element of a light) that uses a lightweight-emitting diode to generate light:
因為發光二極管為光源面積小、分佈較集中，作照明用途時會刺眼，須運用光學設計分散光源。
The VI qualities curve shows the connection among the voltage and current in the system. The horizontal or x-axis represents voltage when the vertical or y-axis represents recent.
Regional keep selling prices may well differ from People shown. Merchandise demonstrated as readily available are Commonly stocked but inventory levels can't be guaranteed.
An LED performs the exact same way. The one big difference is the fact that it emits light when The existing passes as a result of, as the identify implies. This similarity is reflected even within the schematic , as noticed below.
單色性強，由於是單一能級光出的光子，波長比較單一（相對大部份人工光源而言），能在不加濾光器下提供多種單純的顏色。
The LED color (emission wavelength) will transform according to materials made use of. This causes it to be probable to personalize the colour to meet selected wavelength specs demanded for applications that use regular mur led bulbs as light sources (for which criteria exist), like targeted visitors lights and automotive lamps.
Brilliant white LED bulbs Have a very great and refreshing mild that is certainly finest Employed in kitchens, loos or garages.
Check out an electronics shop with a pal or member of the family to check out the televisions available today. You'll probably see numerous types of differing kinds of televisions.
LEDs can are available A variety of different types, shapes and sizes and therefore are picked out depending on the apps They can be used for. Place, electrical power materials and environmental variables may also Participate in a part in how They are really decided on. The most common forms of LEDs are:
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。
They emit mild in specific Instructions, not in all Instructions like regular lighting resources – this allows lights never to be wasted
