Toshiba added a high luminous flux product to the white LED "TL1L4 series" for illumination. The current product has a luminous flux of 130 lm (minimum) when the junction temperature (Tj) is 85°C and the forward current (IF) is 350 mA, while the new product increases this value to 140 lm (minimum). Due to the increase of luminous flux, the new product can meet the requirements of the market for LED lamps with "light efficiency of 110 lm/W or more" (power efficiency of 90%, optical efficiency of 90%, Tj=85°C). The new product is the "TL1L4 series (4A5B type)", which has a variety of color temperatures of 6500K, 5700K, 5000K, and 4000K. The color rendering index of the four color temperature products is Ra70 (minimum). When the ambient temperature (Ta) is 25°C and the forward current (IF) is 350mA, the luminous flux can reach 165 lm (reference value). The new product is manufactured using GaN-on-Si technology developed for lighting LED applications. Use a 3.5mm x 3.5mm lens package. Mainly used for street lamps, searchlights, LED bulbs, downlights and other lighting fixtures.
