LG is joining an industry effort to infuse the humdrum lighting market with the excitement -- and profits, and complexity -- of the computing and electronics business.

Several companies offer smartphone-controlled LED light bulbs these days, but LG Electronics is trying to advance the state of lighting with another approach, too: an OLED table lamp.

The Korean company, which already has a strong home-appliances business, unveiled its OLED Table Lamp on Monday at the Light+Building 2014 trade show in Frankfurt. Instead of using conventional light-emitting diodes (LEDs), its light source is the organic light-emitting diode (OLED) technology that can be formed into a sheet. (Source: CNET.com)

The table lamp, like the company`s new LED bulb, the Smart Lamp, has an LG app for iOS and Android that lets you control the bulb over Bluetooth. The app can adjust the lights to set modes for movies or reading, or dim gradually at night and turn on with an alarm.

Newer electronic lighting technologies also offer consumers some novelties such as variable-color lights that can be tuned for different moods. And some believe that with OLED lighting, homeowners eventually can move to sheets of illuminated wallpaper.
