These days, we are seeing more and more people using Light Emitting Diodes or LED optics over other conventional sources of lighting. These lighting components are used everywhere starting from homes to offices, industrial units, on the streets, car parking areas, and more. One of the main reasons for using LEDs is that they are claimed as more energy efficient and can last longer. Moreover, they have some other unique features that make them the right choice for some applications.
Lens manufacturing companies take into consideration some factors when creating various optical components, including product design, size and form factor, directional light emission, instant on at full output, mechanical failure resistance, dimming and control capability, and more. People also prefer to use lighting products that give improved performance at cold temperatures and have an extended lifetime.
How LED is different from other lighting products?
LEDs are semiconductor devices that produce light through electroluminescence. Incandescent and fluorescent emit light via a heated filament and by using a gas discharge while high-intensity discharge (HID) lamps use an electric arc discharge to produce light.
LED lighting products have a minute chip of size 1 square mm made of several layers of semi-conducting material. Your LED packages may contain just one chip or multiple chips usually enclosed in a lens or encapsulant. LEDs are finally mounted on a circuit board and combined into a lighting fixture, closed to an architectural structure, or made to fit the form factor of a traditional lamp.
LED Product Design
Although not all LED products are built in the same way, the basic components often remain the same. For example, there is the chip along with various components that are needed for thermal regulation to produce the desired spectrum, controlling electrical characteristics or creating the appropriate light distribution mode. Usually LEDs are made of silicone lens, have a phosphor plate, transient voltage suppressor, cathode, bond and metal interconnect layers, thermal bed and ceramic substrate.
Size and Form Factor
The small size of LEDs offers the possibility for innovative, low profile, or compact lighting products. If you reduce the depth of a luminaire, you create more space for ducts, conduit, or other building systems. Even the size of the ceiling plenum could be reduced.
Directional Light Emission
Traditional light sources are used to emit light in all directions. However, there are many applications that require light generally in one or two directions. In such cases, light gets wasted. You require using special LED optics to make directional light sources, but they cause light losses. In contrast, LEDs emit light hemispherically, rather than spherically.
Instant on at Full Output
When using fluorescent lamps particularly compact fluorescent lamps, they not always provide full brightness immediately after been switched on. HID lamps can take more time warm up ranging for several minutes. LEDs on the other hand can produce full brightness almost instantly.
