Toshiba high-brightness, white surface-mount LEDs provide excellent color uniformity

Oct. 21, 2009
Date Announced: 21 Oct 2009 Latham, New York: Marktech has expanded its lineup of Toshiba compact, high-efficiency white light emitting diodes (LEDs) with three new devices in PLCC-2 packages in daylight (or cool) white and two warm whites. These white LEDs are among the brightest white LEDs in Marktech’s current LED product line in this form factor. The daylight white TLWK1100C LED delivers luminous intensity of 1700mcd from a drive current of 20mA. This new device is 200 mcd brighter than the previous generation TLWK1100B, one of Toshiba's most popular white LEDs, and is well-suited for use in automotive and LCD backlighting applications. At 86 lumens per watt (lm/W), it features a luminous flux (typ.) of 5.5 lumens (lm), color temperature of 6500K and chromaticity coordinates of Cx 0.31 and Cy 0.30.Two new warm white devices for general and backlighting applications include the TLWWK1100B and the TLWLK1100B. These LEDs feature luminous intensity of 1500mcd. Both devices are offered at 77lm/W and feature luminous flux (typ.) of 4.9 lm, and color temperature of 3500K and 3000K, respectively. The 3500K device has chromaticity coordinates of Cx=0.40 and Cy= 0.39, and the 3000K device has chromaticity coordinates of Cx 0.44 and Cy 0.40.All three LEDs are housed in a standard PLCC-2 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 114mW and typical forward voltage (VF of 3.2V. Operating temperature ranges from -40ºC to 100ºC.Features• Standard PLCC2 Surface Mount Package• 120º Viewing Angle• Incorporates InGaN/Phosphor Technology• High Operating Temperature Range: -40º ~ +100º C• Typical Luminosity of 1500-1700mcd @ 20mA Pricing and AvailabilityPricing for the TLWK1100 series starts at $0.45 in 5K lots with free samples currently available.
