Normally the minimum mounting height must be respected for the individual recessed lights. The Akzent- or security lights must (illuminant with aluminum reflector) are used (normally included recessed lights). Heat should not be pushed so impose no insulation in transformers or lamp. In the insulation film, it is recommended to cover the recess that above this foil with a metal plate or metal perforated plate. So it can not go waves and bags with too much heat. Normally be difficult or even non-flammable insulation materials are used.

An LED is a semiconductor that emits light when it is sent in the right direction flow through it. Thus, it is an electronic component that emits light directly. The color of light depends on the semiconductor material used. An LED is composed of a chip of luminous material, a lead frame with place for the chip and a housing which protects the chip.

LEDs are small about (2-5mm) and combined they give off a lot of light. One of the properties of a diode is that it is in on the one hand guides the electric current, and stops in the other sense. So if you for example would be a wrong LED connect the flow will be stopped and will not burn. The LED These are basically not broken.

In the 20s the Russian scientist Oleg Losev discovered that diodes radiated light when a current was sent through it. In 1927 he published his findings in a Russian magazine and asked for this patent. With His work remained unnoticed. It took until 1962 before the LED really broke through, Nick Holoyak developed in that year a working LED.
