Basic Principle of LED (Light Emitting Diode)
A light emission diode consists of multiple layers of semiconductor material. When the diode is being used with direct current, the light is a product in the active layer. The light produced is separated directly in or by the reflectors. In contrast with the incandescent reflector lamps, which emit a continuous spectrum, an LED emits light in a specific color. The color of the light depends on the semiconductor material used. Two material systems are used mainly to produce LEDs with high brightness in all colors from blue to red and, through luminescence conversion, also in white. Different voltages are required to operate the diode on direct bias.
LEDs are semiconductor crystals. Depending on the composition of the Crystal components, they emit light in the colours red, green, yellow and blue, when the current flows through them. With the help of a fluorescent yellow, blue LEDs also produce white light (luminescence conversion). Another method of producing white light consists of the mixture of light emission diodes red, green and blue (RBGs). It is used especially when the priority is not to generate white light, but other decorative effects with several bright colors.
With the three colors RGBs, any number of shades of colors can be mixed in varying the proportion of individual colors. Thus, the LED lighting can create fascinating worlds of experience.
Cross-section of the LED
IncredibleFlashlight produces LED lighting in a variety of colors of white light. They range from the warm white of 2700 Kelvin up the neutral white 4000 Kelvin to the cold white 6500 Kelvin similar to daylight, the color rendering index (CRI) in the various shades of white reaches 70 to values well above 90. A luminous efficiency of up to 130 lumens per watt is possible with currently available components.
Advantages of LED Technology
The LEDs offer several advantages over other lighting technologies. Professional users and domestic consumers benefit in equal measure from the limitless possibilities of design based on the variety of colors, compact dimensions and flexibility of LED modules. Based on low power consumption, long service life and increased maintenance intervals, large economic benefits are produced. In addition, the individual LEDs provide maximum reliability even in difficult environmental conditions.
