Aug 28, 2012 Hi there, Chloe! Even though you failed to really know what LEDs were ahead of modern Question, we positive are happy you might have learned about them now!

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。
Merely electrical power it up and look at it go! These are perfect for initiatives where you want a little bit extra action but don't have room for Manage circuitry. You will find even RGB flashing LEDs that cycle by means of Countless shades!
The light depth also is determined by the temperature. A rise in temperature decreases the light intensity of the LED as demonstrated while in the graph.

4V Forward Voltage Fall Every. Naturally we'd want to incorporate a current restricting resistor, right? How would you discover out the voltage throughout that resistor? It is simple:
LED bulbs which have earned the Vitality STAR are matter to very distinct prerequisites created to duplicate the experience you happen to be utilized to with an ordinary bulb—so they can be used for a wide variety of applications.
大多數用來製成發光二極體的物質具有非常高的折射率。這意味著大部分光波會在物質與空氣的介面會被反射回物質，因此，光波萃取對於發光二極體是很重要的論題，大量研究與發展都聚焦於這論題。
Aug 28, 2012 Most of us liked the video clip Using the male surfing! Our favourite aspect was after we saw the lights shining from the glowing snow. We forecast tomorrow's question are going to be about: fried chicken or fried fish.
Regular LED gentle bulbs: Normal LED bulbs disperse mild at a wide angle all over a mur led room. They’re perfect for examining lamps, hallways and also other widespread fixtures for example semi-flush and flush-mount fixtures.
We mentioned luminous intensity a little bit in the earlier segment, but there is more to it than simply putting a amount on how bright anything seems.
This LED can cope with quick bumps to 30mA, but you don't want to maintain that present for also prolonged. This datasheet is even useful sufficient to suggest a steady existing vary (from the third row from the prime) of sixteen-18mA. That's an excellent concentrate on quantity that will help you make the resistor calculations we discussed.
Which means LEDs can easily use light-weight and energy much more successfully within a multitude of programs. On the other hand, In addition it means that subtle engineering is required to make an LED mild bulb that shines light in every route.
