Yiguang exhibited a full range of LED application components at the 2013 Shanghai Electronics Show

In the 2013 Shanghai Electronics Show, Yiguang exhibited a full range of application components, including lighting, display, backlight, automotive, mobile phone, home appliance applications and infrared components, including the new COB full range, ultra-small ITR photointerrupters, distance Sensing components and billboard components, etc.

Yiguang exhibited the medium and low power, XI series and COB component series in the lighting component series. Low-power introduction of new 2835 components, increased heat sink design, reduced overall package thickness, improved luminous efficiency, can be applied to lamps; 5630 components are introduced in 15V high-voltage version, used in bulb ball and spotlight series; XI The 3535 components in the series are sized and cost-effective to replace the high-power 1 watt components on the market, and the Everlight XI3535 is tested with the LM80. COB component series is the key project of this exhibition. JU series 3W to 50W, using high thermal conductivity ceramic substrate, good heat dissipation effect, easy to install and improve process convenience; double color temperature series color temperature can be adjusted to ANSI 2700K to 5700K, all The luminous efficiency of mixed light color temperature can reach more than 100 lm/W; M08/M09 COB series uses high thermal conductivity mirror aluminum substrate, which has the advantages of high efficiency and convenient installation, even if the driving power is increased under the appropriate heat sink, There is still high brightness and high stability performance.

Everlight currently has the world's smallest package size billboard component: 18-038 (1.0mm x 1.0mm), three-in-one surface mount package with black substrate, its small package size, making the pixel spacing between LEDs smaller It can arrange high-definition display screens to achieve high-resolution, color-contrast visual effects. 18-038 is rare and light, suitable for indoor small-pitch explicit screens, and can achieve applications below P 3 It can definitely meet the strict requirements of the market for indoor billboards. This year, Everlight launched the ultra-compact control photointerrupter ITR1205ST11A/TR, which consists of an infrared light-emitting diode and an NPN silicon phototransistor. It is integrated through a dual molding process, compared to traditional photointerrupter products. This unique process has a 74% reduction (2.7mm) and advanced packaging technology for space and groove widths of only 1.1 mm and 0.3 mm, allowing for higher accuracy Or detection sensitivity, especially suitable for digital camera applications.

For the high potential backlight market, Everlight launched the new 99-826 series (4206), which is used in backlit mobile phones and has the advantages of high brightness and reliability optimization. The side-projection TV introduces the new 62-122 series (8520), which has the advantages of high brightness and small package, and can provide customers with the best light source choice for light guiding technology.

The new 45-11S (3020S) model is introduced at the show, with a maximum operating current of 60mA. The special heat sink design at the bottom of the bracket optimizes heat dissipation and enhances product reliability. It is widely used in automotive interior applications, including automotive entertainment systems and dashboards. , switch indication, LCD backlighting, etc. The full range offers high-brightness illuminance and is certified by the AEC-Q101 for high performance.

In the mobile phone market, Everlight introduced a series of components for flash, indicator light, button backlight, auto focus and infrared sensing. For the needs of different customers, the ELCH01, which is highly cost-effective (cost-effective), the ELCH08 with high brightness, and the high-quality (13 million or more) project, the ELCU02 and ELYU03 with high uniformity and high central illumination are used. The two models are modular in design and have been subjected to secondary optical light collection, so no need to use a lens, the light effect is better and relatively stable, and the process can be accelerated.
