Vishay Intertechnology, Inc.（NYSE 股市代号：VSH）推出业界首个采用 CLCC-2 扁平陶瓷封装且基于蓝宝石 InGaN/TAG 技术的高强度白光功率 SMD LED 系列。VLMW84..器件可降低高容量应用的成本，它们具有 25K/W 的低热阻以及 5600mcd～14000mcd 的高光功率。
凭借 0.75mm 的超薄厚度，VLMW84..LED 的 CLCC-2 扁平陶瓷封装可实现能够达到最大光输出的额外电流驱动，同时保持长达 50,000 小时的高使用寿命，这使它们在热管理为主要考虑因素的空间受限应用中成为理想光源。
这些新型器件专门针对汽车与运输、消费类及普通应用中的显示屏背光与照明而进行了优化。Vishay CLCC-2 LED 是 CCFL 显示屏背光装置的环保替代产品，其在小型封装 (3.3 mm x 3.4 mm) 中具有出色的光效率、较长的使用寿命以及出色的省电特性。典型的终端产品包括照相机的闪光灯；应急灯与标志；汽车仪表板以及外部照明装置，例如刹车灯及转向信号灯。
这些 LED 可提供 27000 mlm 的典型光通量以及 100mA 时 40 lm/W 的光效率。这些器件每封装单位的光强度比 IV 最大值/IV 最小值 ≤ 1.6，它们具有高达 5V 的正向电压、60°的半强度角。
Vishay Releases Industry’s First White Power SMD LEDs to Utilize InGaN/TAG on Sapphire Technology in CLCC-2 Flat Ceramic Package With Ultra-Low 0.75-mm Profile
Devices Combine Low Thermal Resistance Down to 25 K/W and High Optical Power From 5600 mcd to 14000 mcd for High-Volume Applications
Vishay Intertechnology, Inc. (NYSE: VSH) released the industry’s first series of high-intensity white power SMD LEDs in the CLCC-2 flat ceramic package to offer InGaN/TAG on sapphire technology. Designed to reduce costs in high-volume applications, the VLMW84.. devices offer low thermal resistance of 25 K/W and high optical power from 5600 mcd to 14000 mcd.
With an ultra-low profile of only 0.75 mm, the CLCC-2 flat ceramic package of the VLMW84.. LEDs allows the additional current drive for a maximum light output while maintaining a high service life of up to 50,000 hours, making them ideal light sources in space-limited applications where thermal management is a key consideration.
The new devices are optimized for display backlighting and illumination in automotive and transport, consumer, and general applications. An eco-friendly alternative to CCFL display backlighting, the Vishay CLCC-2 LED offers excellent efficiencies in brightness, lifetime, and power savings in a compact package (3.3 mm x 3.4 mm). Typical end products include flashes for cameras; emergency lighting and signs; and automotive instrument panels and exterior lighting, such as brake lights and turn signals.
The LEDs offer a typical luminous flux of 27000 mlm and optical efficiency of 40 lm/W at 100 mA. The devices feature a luminous intensity ratio per package unit of IV max/IV min ≤ 1.6, forward voltage up to 5 V, and 60° half-intensity angle.
