Five Steps of the Production of LED Lighting Products
1. Five Steps of the Production of LED Lighting Products
Emitting Principle of LED
Since the generation of the outside lighting, the lighting is divided into three periods: the era
of filament lamps (incandescent), the gas bulbs era (Fluorescent), the era of the
semiconductor light-emitting (LED). And we always put attention to the longest history of
incandescent and mainstream LED. Regardless of how the development of the era is, the
lighting industry's production processes are surprisingly similar. And there are various kinds
of led lights in our daily life, such as LED high bay, led street light and so on. When electron
goes through the layer of semiconductor material and it stimulates semiconductor material
resulting in converting electrical energy into light energy and this is the emitting principle of
led. However, the single semiconductor light-emitting ability is weak, so t a lot of single layer
materials have to be stacked up and pressed into the composite material, and this is epitaxial
wafer. So, LED luminous efficiency is determined by the layers pressed into same thickness.
The thinner the monolayer material is, the more layers can be superimposed and the higher
the luminous efficiency is. Now the general thickness of each layer is only 2-20 microns,
which also determines the epitaxial wafers production is the most difficult part of the entire
LED production process.
Cutting is the Core of LED
It is the equivalent of the filament withdrawn from the tungsten material while the difference is
that the epitaxial wafer after cutting is a block-shaped. Due to the special structure of
epitaxial wafers, it is extremely difficult to cut optical core in good shape. It not only requires a
vacuum environment, but also needs professional cutting machine. Currently there are only
two manufacturers in the world having this cutting machine.
Put the Core into the LED Chip
Chip to an LED is as lampholders to bulbs, and it is the power supply part. "Chip" is very
important equipment for LED desired effect, because the LED puts very high requirements
on current. For example,high bay LED lighting has high demands for the current.
Package LED Chips into Luminous Body
LED chip package just like add the lampshade to filament lamp holder to make into light
2. bulbs. The shape of lampshade may vary depending on the desired, but the packaging
technology determines the service life of the luminous body.
Lighting Applications of LED
Just like the use of incandescent bulbs, according to the different functions and needs, it is
assembled into a variety of LED products. For LED lighting, the first three steps of epitaxial
wafers, cutting and chip are upstream, the fourth step of the package is the middle reaches,
and the fifth step of the application is downstream. We need to use more energy to break
through these issues that.
