Original Press Release:

Toshiba High-Brightness, High Reliability White Surface Mount LEDs Provide Excellent Color Uniformity for Backlighting Applications

Latham, New York: Marktech has expanded its lineup of Toshiba White surface mount LEDs aimed at general and backlighting applications with the release of the Toshiba TLWxK1109 series. The new 1109 series LEDs are offered in three Lighting Industry standard color temperatures of 3000K, 5000K and 6500K. As with all Toshiba products, the highest level of manufacturing processes are used to insure a very robust LED for use in all lighting applications.

The daylight white TLWK1109 LED delivers a Luminous Intensity of 3200mcd and is well-suited for use in linear lighting and LCD backlighting applications. At 76 lumens per watt (lm/W), it features a luminous flux (typ) of 11 lumens (lm), and color temperature of 6500K. In addition this LED series includes both neutral and warm white devices that are perfect for use in instrumentation and backlighting applications. The TLWNK1109 neutral white LED has a Luminous Intensity of 3200mcd and is 76lm/W with a Luminous Flux of 11lm (typ) and color temperature of 5000K. The TLWLK1109 warm white LED has a Luminous Intensity of 2500mcd and is 60lm/W with a Luminous Flux of 8.6lm (typ) and color temperature of 3000K.

All three LEDs are housed in a PLCC-4 surface-mount package that measures 3.2mm x 2.9mm x 1.9mm. Their high brightness white light output is a result of a combination of a blue InGaN (indium gallium nitride) LED and a yellow-emitting phosphor. The devices offer efficient operation with maximum power dissipation of 200mW and typical forward voltage (VF) of 3.6V. Operating temperature ranges from -40ºC to 100ºC.
