What Is LED Good For?

Flashlights

• LEDs are clustered in arrays to additively increase the output of the light. LEDs allow increased battery life, and provide a level or light output impossible with a conventional, single-lamp flashlight. LED-based flashlights find utility in police and military applications, because there is no filament to damage and it offers a smaller profile.

Televisions

• Many liquid crystal televisions use LEDs as their primary source of light. LEDs offer a high level of control over the total output of the set, and are individually addressable by the processors in the television. In other words, color-specific LEDs can generate a wider range of bright white and deep black over their conventional cold cathode lamp based cousins. LED LCDs are popular among those that look closely at efficiency when choosing their electronics and appliances.

Vehicle Applications

• Many vehicles use LEDs in headlamps, taillights and internal lighting. These lights are low-maintenance, reducing the likelihood that one lamp will go out in a cluster. Costs for consumers reduce over time, given that LEDs will probably outlast the typical period of ownership for most vehicles. LEDs come in a variety of colors; given their intense purity, dash lights, accent and turn lights can match the hue of modern Xenon and high intensity discharge bulbs found on many vehicles.

OLED

• Organic light emitting diodes (OLED) offer exciting opportunities for innovative manufacturers. OLED is flexible, thin and energy-efficient. For portable devices and video displays, the ability for OLED panels to offer high color saturation, extreme viewing angles and extreme efficiency is intriguing. OLED facilitates even thinner and smaller electronics at higher light output and more intense colors.
