Toshiba Lighting Technologies demonstrated a room that uses white light-emitting diodes (LEDs) for indoor lighting at the "Lighting Show." "We want to make people see that the white LEDs currently on the market are bright enough to be used for lighting." The commentator). ![]()

Figure 2: Incandescent color in the living room The company is displaying an office with neon lighting and a living room with incandescent lighting. 6500 white LEDs (Figure 1) are mounted on the ceiling for office lighting. These diodes were mounted in five stencils (400 mm x 400 mm) with 1300 in each stencil. The white light emitting diode is formed by adding a fluorescent material that converts blue light into yellow light to the blue light emitting diode. Since the red light has a low brightness, it looks like a slightly blue white light. A total of 1,440 white LEDs were installed on the ceiling of the incandescent living room (Fig. 2). 360 diodes were mounted in a circular template with a diameter of slightly less than 300 mm, and a total of four such templates were used. This template uses a white LED with a fluorescent material that increases the brightness of the red light. "Although the luminous efficiency of white LEDs is only 2/5 of that of fluorescent lamps, the current consumption of white LEDs is greater than that of fluorescent lamps. However, the research progress of improving the luminous efficiency of white LEDs Very fast (the company's commentator), by 2007 to 2010, the luminous efficiency of white LEDs will be equal to or higher than that of fluorescent lamps.
