The future of light
The lighting market is constantly changing. LEDs and OLEDs are now positioned to replace classic lighting in residential and professional spaces. These increasingly efficient and innovative lighting solutions will change the way the world looks to the future of lighting. At Verbatim, our innovative Violet Chip technology and OLED panels combined with the backing of our parent company, Mitsubishi Chemical Holdings Corporation (MCHC), position us as a leader in this market.

The LED (Light Emitting Diode) was first discovered almost a century ago. In the early 1960’s the first practical devices were developed in the US. These were red LEDs used for indicators and alphanumeric displays. Since then blue, green and violet light emitting LEDs have been developed and research has concentrated on achieving lower costs with higher light output and efficiency.
In order to create the white light needed for general lighting the LEDs are surrounded by phosphor materials that transform the monochromatic light from a blue or near-UV LED to broad-spectrum white light. The development and sale of LED substrates, phosphors and encapsulants are a key focus for MCHC.
LED bulbs and lighting fixtures combine the methods and materials described above, electrical circuits to drive the LEDs, an optical lens to extract and focus the light, and heat sinks to maintain the LED’s optimum operating temperature.
Retrofit light bulbs are now available to replace most incandescent and CFL bulbs. The efficiency of an LED bulb is approximately five times that of a standard incandescent bulb, so that even though the initial cost of an LED lamp is higher than the incandescent type the additional cost is more than recovered through the lower energy usage and much longer life of the LED bulb. LED lamps are also environmentally friendly because they lessen the need for power generation and do not contain hazardous materials such as mercury.
Lighting in homes and businesses typically accounts for about 20% of electrical energy use. Conversion of incandescent lighting to LED-based lighting can have a major impact on national energy usage and individual carbon footprints.
