How LED's Work
Light Emitting Diodes (LED's) are made by pushing an electric current through two abutting insulators that have been doped by adding an impurity.
Silicon is an insulator with all its electrons tightly bound. If a small amount of antimony is added to it the extra atoms have spare electrons. (N Type) If another piece of silicon is doped with boron the additional atoms will have extra holes. (P Type). When the N and P type silicon is butted together spare electrons can flow from the P into the holes in the N silicon. When an electron fills a hole a small particle of light is given off. A battery pushing electrons into the P and emptying the holes in the N can keep a current flowing creating the light source.
Modern LED's have developed this simple idea so it seems unrecognisable but the basics remain the same.
1. The LED must be supplied with Direct Current, and this must flow in one direction through the P type to the N type
2. Mains Voltage is 230 Volts and the driver has to convert this to a direct current to run the LED
3. Some drivers are specified in milliAmps and some (mostly LED tape) in a constant Voltage. The Volts and Amps are closely related but it is vital that only the driver specified by the manufacturer is used.
4. The join between the the semi conductors will break down if it is overheated so never exceed the power (milliAmps) specified.
LED Downlight Colour
The descriptions Warm, Cool,Natural and Daylight are a bit vague so the precise colour temperature is usually given for clarity.
Here is a guide:
2700K This is the warm colour of halogen and tungsten filament bulbs
3000K This is the colour of LED Warm White, it is slightly whiter but the effect is crisper than the halogen
4000K This is called Cool White or Natural White. It is noticeably whiter than Warm White. It is the type of light you see in offices and supermarkets.
6000K This Daylight. It is a cold white light which is often used in a medical inspection room as it is close to sunlight
