With the increasing demand for smartphones, the market request for mobile phone pixel has been rising. To provide the best photography effects for customers, mobile phone manufacturers require the specification of phone flash should be upgraded. At present, the brightness range of Flash LEDs is between 180~280lm, with each smartphone using 1-2 LED pieces. Benefitting from the booming up smartphone market, the usage volume of Flash LED has continued to grow.

Aiming for the business opportunity, the Taiwanese LED packaging manufacturer, Edison Opto, has invested in the R&D and production of Flash LED, and introduced the industry’s brightest Flash ES03 which breaks through the technology threshold to obtain the exclusive phosphor film patent. The package size of Flash ES03 is 2.0x1.6mm (2016) which is the mainstream dimension in Flash LED market. Flash ES03 gives off high brightness (320lm which is driven by 1A) within ultra small emitting area (only 1.1x1.1mm). Compared with the traditional spray coating process, phosphor film features high color uniformity and can achieve the optimum brightness performance with second optical design (the efficiency is higher than spray process by 10%). Furthermore, the small package dimension makes design more flexible especially suitable for closely packed LED array module. In the aspect of color temperature control, the CCT range of ES03 is much narrower than spray process which demonstrates that Edison Opto can control the color consistency effectively and provide stable quality products.

Flash ES03 has been introduced into mobile phone flash market and successfully entered the supply chain of leading cell phone manufacturers. Besides, Flash ES03 can be applied in automotive lighting and medical applications (such as endoscope). In addition to the white ES03, Edison Opto has also launched full-color Flash LED products which can be widely used in warning lights, stage lights, mood lighting and decorative lighting.
