In order to increase the on-current, this time, while increasing the output power of the LED chip embedded in the product package, the connection method of the LED chip and the package is also carefully designed. Among them, the effect of improving the connection method is the most significant. Detailed technical information has not been published, but it is reported that the heat dissipation of the LED chip is improved by improving the thermal conductivity between the LED chip and the package. When a large current is turned on, even if the LED chip generates heat, the heat of the chip can be efficiently conducted to the package material. (Reporter: Okubo Satoshi)
OSRAM publishes L with a working current increase of 2 times
Introduction: OSRAM Opto Semiconductors GmbH has released the "Platinum Dragon", a light-emitting diode (LED) with a maximum operating current of 1A, which is equivalent to twice the previous product of the company. Available colors include white, blue, green, yellow, orange (amber), and red. Applicable to display devices such as in-vehicle equipment, lighting equipment, traffic signals, and backlights for LCD panels. Among them, the white LED has a beam brightness of 75 lm when the current is turned on at 700 mA (measured value at an ambient temperature of 25 ° C). The luminous efficiency is 30 lm/W. The company's previous product "Golden Dragon" has a brightness of only 45 lm when connected to a current of 350 mA. Platinum Dragon plans to start shipping from the end of 2006 to the beginning of 2007.
