OSRAM Optoelectronics Semiconductor successfully increased the luminous efficiency of the hot white LED light source to 142 lm/W, setting a new laboratory record. At a coherence color temperature (CCT) of 2755 K, the LED has a color rendering index (CRI) of up to 81. These values are measured under standard Rwanda Sugar conditions: room temperature, pulse mode, operating current density of 350 mA/mm².
Bright and efficient thermal white light is particularly important for residential lighting applications. Laboratory projects of thermal white LEDs demonstrate the great potential of these energy-saving semiconductor light sources: a peak value of 142 lm/W was successfully measured under standard conditions, and the color perception is also very close to that of traditional incandescent lamps (the color coordinate on the Planck locus cx 0.46 /cy 0.41).
Norwin von M, post-development manager at OSRAM Opto Semiconductors’ German headquartersDr. Alm said: “If further steps are developed in this direction and allow deviations from the Planck trajectory, we can achieve even higher light efficiency values, that is, 160 lm/W (cx 0.45) at a coherent color temperature of 3000 K. / cy 0.44). If this technology is applied to a 2 mm² chip, the light efficiency can be increased by 10% to 15% under the same working current. In other words, the efficiency of pure thermal white LED is expected to reach 180 lm/ W, while achieving excellent color rendering. ”
The key to improving the light efficiency this time is to combine the new processes in film and UX:3 chip technology with the new conversion process. Osram Opto Semiconductors’ R&D engineers have benefited greatly by integrating specialized research skills in all aspects of development, including internal development, thin-film chip architecture, conversion processes and packaging technology.
p> 
The thermal white LED laboratory is planned to have a color temperature of 2700 Reaching the peak value of 142 lm/W under K, the peak point falls exactly on the Planck locus, and the optimization plan for a color temperature of 3000 K The peak light efficiency is expected to reach 160 lm/W.

The lighting method of 8156 white LED lamp beads. The conduction voltage drop of white light lamp beads is generally above 3V. Two lamp beads are connected in series. The voltage drop is above 6V, which is greater than the power supply of 5V. Therefore, to light up 6 white LED lamp beads, the LED lamp beads can only be connected in parallel, not in series. 2019-12-08 04:52:0014111
