LED is an electric component that emits light when connected to direct current. It emits light in visible light as well as infrared and ultraviolet. With low energy consumption, small size, longer lifetime and faster switching than incandescence lamps and because of that, they have a wide range of applicability.
The light-emitting diode (LED), a semiconductor diode which can emits light when voltage is applied to it, used in electronic devices, and it is one of the most energy-efficient and rapidly-developing lighting technologies, has the potential to mainly change the future of lighting in all over the world.
The wide range of application of the light emitting diode (LED) which can offer, from your cell phone to the large billboards is increasing rapidly according to the distinguished aspects and specifications that it has, while they are very tiny in shape and consume very little power
LEDs easily offer lots of utilities over other lighting sources. Consumers, specialists and professional users can get multiple options and choices that are based on colors, dimensions and the flexibility that LED modules give, also LED lights offer high level of reliability even in the most difficult conditions
“SMD” surface mounted device, LED chip is integrated with a printed board. This type of LED is more popular due to its variety and multiple use, you can find it in almost every lighting type and even in your notification light on your cell phone.
“COB” chip on board, comes with 2 contacts and 1 circuit, which makes not able to make multiple color changings like in the SMD.
LEDs can easily pass 50,000 working hours, in comparing to other light sources, luminous flux can be just a little bit reduced over operation periods.
As much cooler is the device, as LED`s life span is longer, more effective and brighter, when releasing light, heat occurs which easily effects the life cycle and luminous flux of the LED, here comes the necessary need of the heat sink and choosing the best installation way to divert heat.
If a LED is exposed to such forces, this can have a negative effect on its operating life, or even can be destroyed.
Whenever the current is lower, less energy is released and heat production is lower, which effects directly on the operation life
It is directly influenced by the light comes out from the chip itself. Like built-in reflector ages a lot in the first few hundred operating hours as a result of the high intensity and luminance of the light emitted by the chip.
Bad material of the housing affect directly but in a passive way to the light comes out from the chip itself Humidity
chemical influences vary depending on the location, all environmental conditions must be taken into account
There are plenty of LED applications that you can do it yourself and other needs a specialist`s assistance.
From LED spot light to LED strip lights and LED modules including indoor and outdoor applications
From urban lighting, for street and city lighting, façade lighting, landscape lighting,
Industrial, Offices and Residential lighting.
