South Korea's Seoul Semiconductor will launch a surface-mounted white LED "LCW100Z1" with a luminous efficiency of 120 lm/W (published in English). In addition to the arched lens, the LED also uses a metal base plate to increase luminous efficiency and heat dissipation by about 20% compared with the original product.
This time, there are products of different color temperatures such as "cool white", "pure white", "warm white" and "natural white". The external dimensions are 3.5 mm x 2.8 mm x 1.6 mm. The amount of light at a viewing angle of 120 degrees can reach 7.8 lm (input power is 0.06 W) at a turn-on current of 20 mA and 14.3 lm at a turn-on current of 40 mA (both cool white products).
Seoul Semiconductor said that if the product can replace the Top View LED and LCW100Z1 currently on the market, it is expected to be equipped with fluorescent tubes. At present, the company has begun to supply some lighting manufacturers. (Reporter: Yoshizawa)
