LED Flash has high stability, low illumination angle, low voltage drive, no need for charging and long life. Flash LED has become the standard for smart phones. According to the 2013 Flash LED market conditions, mainstream specifications fall. The driving current is 1000mA, 500mA and 350mA, and the brightness of the high-end Flash LED falls between 240-250lm.
According to Philips Lumileds' LUXEON Flash series, the average brightness is about 220-240lm at a driving current of 1000mA. Philips Lumileds has also introduced a product with a driving current of 2000mA and a brightness average of 500lm. The OSRAM CERAMOS series has a lumen current of about 500-140 lm at a drive current of 500 mA. The OSRAM also has a product with a drive current of 1000 mA and a brightness of between 180 and 330 lm. The latest CL-773A2 series of Japanese manufacturer CITIZEN also introduced a product with a driving current of 1000 mA and an average brightness of 260 lm.
According to the industry, although all smart phones are equipped with Flash LEDs, many white-label mobile phone Flash LEDs have insufficient brightness, and this type of Flash LED is also known as "fake flash" in the industry. The industry believes that the specifications of Flash LEDs will move towards M-type development in 2014. Under the driving current of 1000mA, the Flash LED with brightness of 240-250lm will continue to play the middle and high-end mainstream. On the other hand, if customers have reduced cost considerations, In addition, the introduction of the model is a low-end model, the use of Flash LED will fall in the drive current of 350mA, the brightness is below 75lm specifications.
