Toshiba demo studio with LED spotlight open ultra high power white LED

Toshiba lighting technology at the Tokyo International Convention and Exhibition Center held in the "Lighting Fair 2009" (March 2009 ~ 6 ~ 3) on display for the studio, such as white LED spotlight "AL-LED-FS-6". The company's exhibition area built a simulation studio, the light in the simulation of the host's body to show the color of the coordination.

Previously the studio spotlight has been using halogen bulbs. Because the light of the halogen bulb contains infrared and ultraviolet light, the person under the lamp will feel hot, and the color of the object will be weakened. The use of white LED light source can solve these problems.

Toshiba lighting technology in the exhibition area, but also carried out a demonstration of non heating spotlight. At the same time, side by side with a halogen bulb spotlight and the use of white LED spotlight irradiation, the hands are placed under the lamp to compare whether the feeling of heat. Comparison of the conditions: the location of the hands of the illumination are 3300lx, the color temperature halogen bulb is 3200K, white LED is 6500K, power consumption halogen bulb is 500W, white LED is 100W. Because the position of the hand is closer to the spotlight, although it will feel some of the heat of the spotlight itself, but in the white LED light does not feel the heat radiation.

Toshiba lighting technology also exhibited a white LED used in the spotlight. The rated power consumption of white LED is 75W, the luminous flux is as high as 6000lm, and the luminous efficiency is as high as 80lm/W. The average color evaluation number (Ra) was above 85. Life of 40 thousand hours. Each spotlight comes with 1 such white LED.

The overall size of the packaging area of 75mm * 56mm, thick 2mm. As a single package white LED, the package area is quite large. The package is equipped with 1000 small and small blue LED chip, the combination of yellow phosphor on the chip, so as to get white light. Because of the large input power, the size of the package is increased to increase the heat dissipation area. That is, the use of 1mm square LED chip to reduce the number of large number of packages, the package size can not be reduced.
