Light Emitting Diode (LED) is a semiconductor crystal in which current can flow only in one direction and part of its energy is converted into light. It has a very narrow band, ie always has a certain color, depending on the type of semiconductor. White LED crystal with blue light that illuminates the special phosphor and white light it emits. Unlike other light sources, the voltage on the LED is driven less and is directly related to the color of light – between 1,6 V to 3,6 V and red to blue and white. The light output depends on the current and the consumption of electric power. For example, in 1 W blue LED has a flow 10 lm, and the green and white are 30 lm, red – 44 lm. To ensure the desired values of voltage and current in the LED lighting fixtures must have an electronic unit powered by the network. Many of these units provide an integral value of the current changes in the mains voltage. LED lights in recent years rapidly penetrate all areas of lighting. Initially as a decorative and illuminated, they can now even replaced the bulbs and fluorescent tubes from lighting facilities, offices, shops, hotels and more.

The biggest advantages of LEDs are their economy and long life (about 50,000 hours). Produced by these lamps are almost limitless and virtually maintenance free. By investing in LED lighting, you save on their energy bills and maintenance. Lamp life reaches 50,000 hours under normal operating conditions (room temperature and normal humidity). All models have LED lamps “systems for samoremont” – if they burn one or more LEDs, it does not affect the work of others. Thus, further extends the life of the lamps. LED lighting is regarded as particularly appropriate for dekorativno functional lighting steps, paths, raised levels catwalks and suspended ceilings in the halls. In addition to the marking of certain sections, LEDs offer wide opportunities for realization of various color effects, including a description of all circles and irregular shapes.

Other advantages of LED lighting are good possibilities for adjusting the light output, long life without maintenance, low energy consumption and low voltage power supply. Installing LED lighting optimize energy costs and increases safety lighting in the halls, offering unique opportunities to achieve specific light comfort of the room. All these characteristics create conditions for realization of the desired effect as the color and lighting. No radiation of ultraviolet LEDs and infrared, as in incandescent filament. Finally LED lights are environmentally friendly, contain no gases and mercury

News LED Lighting – IP Protection (Rating)

The resistance offered by the fixture to the penetration of solids and liquids is indicated by the IP (Ingress Protection) rating. This is a 2 digit number, the first number identifies the degree of protection against the ingress of solids and the second number against liquids e.g. IP65 indicates total protection against dust and protection against low jets of water.

We are witnessing a rapid rise within a few years of LED lighting. This irreversible process will be accelerated along with their appreciation. Additional accelerator that are adopted in the EU for a phased ban on incandescent bulbs, including halogen, and their gradual replacement with energy saving, including LED are especially promising.
