New Sharp-LEDs: Small, Efficient and Bright

In addition to the Led lighting Module “Zenigata“, Sharp plans to expand its Led Line-up with white and RGB high brightness chip LEDs. It consists of 21 different types of white light LEDs and 11 different types of monochrome and RGB LEDs.

The company notes they offer a high light performance of up to 90 lumen per watt. In addition, they have an extremely long service life: depending on the type, 40,000h at a substrate temperature of up to 80°C cause extended maintenance intervals to contribute to low operation costs in addition to the high energy efficiency.
 
Sharp notes the new LED components are made for the use in versatile application areas, which require a high amount of brightness with a compact form factor at the same time. This gives designers more freedom and flexibility when creating illumination systems. Besides common applications such as backLighting for LCDs or keypads chip LEDs are used for example for general illumination, surgical spotlights, as status signals for industrial applications and for indoor mood lamps as well.

Due to different phosphor mixtures the LEDs reach a colour rendering index (CRI) of up to 90 for a highly genuine reproduction of colours and details, Colour temperatures of white light LEDs are in the range of 2.200K to 11.500K.They are available with radiation angles of 120° and 130°. The white LEDs generate a light output of up to 6.4 cd at a power consumption of 0.01 to 0.2 W.
  
In any case the white light LED chips are of convincingly compact design, as standard 3228 package with a height of 1.9 mm and 0.9 mm as well as ultra small package of 1.6 x 0.8 mm with a minimum height of 0.2 mm. Since they require only so little space the white LEDs are predestined to replace conventional lamps in commercial applications like shop and decoration lighting. But they will be also used as an illuminant in solar driven and normal streetlights.
  
Furthermore, Sharp is offering brick-shaped multi-chip SMD LEDs, so called Flash Bricks that can be processed by reflow soldering. Despite their small size dimensions of 2.6 x 1.6 x 0.7 mm they provide a high light performance of up to 39 lumen. They are particularly suited for applications which require a high brightness providing only little space for design-in at the same time. Flash LEDs as well as Side Shoot LEDs which are used for mobile phones and other portable application will complete the line-up of white light LEDs.
  
In addition, Sharp is offering a portfolio of monochrome colour and RGB LEDs. They are also available in different packages and sizes.
  
Samples are already available from Sharp sales offices or distribution partners throughout Europe.
