Nichia Chemical Industry has developed a white light-emitting diode (LED) module with a beam of 1000 lm. “The brightness of this product is the highest in the world in white LED modules (Figure 1), around 600lm†(the company). The module has a mounting area of ​​40mm x 40mm and a thickness of 10mm. The power consumption is 30W when the output beam is 1000lm. The maximum input power is 50W. The mounting substrate is equipped with a plurality of blue light emitting diode chips and combined with a yellow phosphor material. The blue LED chip size of the product is "larger than the usual variety" (the company), but no details have been published. Also declined to disclose the number of installations. The productization period has not yet been determined.
Figure 1: Prototype with a beam of up to 1000 lm
The white LED module shown here has a luminous efficiency of 33 lm/W, which is equal to or higher than the white LED currently on the market. In general, as the output power increases, the temperature inside the white light emitting diode module rises, so the luminous efficiency decreases. In addition, if the size of the light-emitting diode chip is increased, an electric field distribution is generated inside the chip, which also causes a decrease in luminous efficiency. This time, "The details cannot be disclosed, and the luminous efficiency can be improved by improving the electrode structure and packaging technology of the blue light-emitting diode chip" (the company).
Figure 2: Prototypes with luminous efficiencies up to 50 lm/W
In addition, Nichia Chemical Industry disclosed to the public for the first time a white LED module with a luminous efficiency of 50 lm/W. The company once disclosed the white LED module at the Society in early 2003. In a 5mm diameter shell-type package, the beam is 3.6lm when a +3.6V voltage is applied at 20mA. A blue light emitting diode chip of 300 micrometers by 300 micrometers and a yellow phosphor material are combined. The company used the white LED module as a lighting device to illuminate the booth (Figure 2).
