Know Everything about LED Philips Lighting
Light Emitting Diodes or LED lights use electro-luminescence and semiconductor technology to generate light. The LED lamp uses a tiny crystal made of semiconductors that uses reflectors and other elements to focus light onto a single point and make it brighter.
The popularity of LED lamps can be attributed to their efficiency and energy cost-saving features. Recent advancements in white LEDs have led to a surge in popularity. Buying a LED light nowadays is as simple as going online and browsing a catalogue like the Philips lighting price list.
How LEDs Work
Basically, LED lights use electricity on a semiconductor material to generate electroluminescence – a phenomenon where materials emit light when electricity is passed through them. In the case of LED technology, this is how the process flows:
· Semiconductor materials like Silicon or Germanium are treated to have an electron shortage.
· This electron shortage is then filled by passing electrons or electricity.
· This includes a process of adding other elements to the semiconductors to change their properties and create two distinct semiconductor types in the same crystal.
· This set of semiconductors makes up a diode and constitutes most LED lighting solutions like Philips Lighting.
OLEDS: An Introduction
Other than standard LED lights, there is one other variant – OLED. OLED lamps use carbon-based organic molecules within their layers that emit luminescence. OLED constitutes the following:
· A layer of organic electroluminescent material that is sandwiched between two different electrodes, one of which is transparent to let photons escape and generate light.
· Like LEDs, electricity is passed through a semiconductor to generate luminescence.
· The main difference here is the fact that OLEDs are carbon-based using either of two compounds:
o Polymers
o Small molecules
Uses of OLED Technology
· For manufacturing Displays– This includes manufacturing
o Smaller devices like Phones and media consumption devices – laptops, tabs, portable media players, etc.
o Larger devices like Televisions and computer monitors
· For manufacturing Lamps – OLED technology is used to manufacture short distance indoor lamps that produce diffused light.
Benefits of OLED Technology
· Wide Applicability: OLED technology has potential uses across several new and innovative fields which has never seen the usage of lighting technology.
· Energy Efficiency: Compared to television and computer monitors made of LCD, OLED screens offer a substantially more energy-efficient alternative
· Unmatched Portability: OLED units are significantly thinner and lighter as compared to traditional LEDs making moving around easier
The Road Ahead for OLED Technology
OLED screens will be significantly thinner for both computers as well as TVs in the future. Other new and innovative usages will include:
· Transparent “heads up” displays
· Flexible Displays
· Flat lights that can be rolled on the sides of vehicles and buildings
· Camouflage display for military usage
· New and upcoming photovoltaic applications
OLED technology is still a work in progress but in time will be much more affordable as they require lesser parts to be assembled as compared to LEDs.
