What is an LED?
The LED (Light Emitting Diode) is a semiconductor component that only allows electricity to pass in one direction. If current flows in the forward direction, the LED emits light radiation, depending on the semiconductor material and the doping.
White light is created when the blue light from an LED chip hits a yellow fluorescent substance that is located in an applied silicone layer. The blue light from the LED and the yellow light from the phosphor mix to form white light. Depending on the composition of the fluorescent material, you get the desired light color from warm white to daylight white.
>>The darker the LED (bright yellow to yellow / orange), the warmer the color
These are LEDs that produce 3 different colors (red - green - blue). In terms of performance, however, RGB LEDs are limited.
SMD LEDs (Surface Mounted Device)
The LED is soldered directly onto the circuit board. they allow
a very narrow and simple industrial assembly.
>> Individual points of light and their multiple shadows can
can be reduced with a diffuser or with coordinated lenses.
COB LEDs (Chip On Board)
The "unpackaged" semiconductors are placed directly on the substrate
(Carrier material) applied. The technical lighting advantage of the COB
Module lies in the homogeneity of the light emission.
With a COB LED, a consistent cone of light is created with a clear
Advantages of LED
Very low power consumption, high light output
Insensitive to vibrations and shocks
Long service life (up to 50,000 hours)
Do not give off any heat in the direction of light
No switch-on delay (the case with energy-saving lamps)
Disposal not as hazardous waste (the case with energy-saving lamps)
Relatively expensive to buy
Big differences in quality: cheap LED lamps lose light intensity relatively quickly
The multitude of LED variants and options can lead to incorrect product choices
