Luminous intensity LED manufacturers are given the means LED lights Shenzhen led housing in 20mA current, the maximum luminous intensity of the point and the best perspective on the center position. LED package when the top of the lens shape and the LED chip position from the top of the lens determines the angle and LED light intensity distribution. Generally speaking the same LED larger perspective 30w led shell, the smaller the maximum luminous intensity led lights shell, but the cumulative luminous flux in the entire three-dimensional hemisphere surface unchanged general LED luminous life is very long, manufacturers are generally designated as 100 More than 000 hours, but also pay attention to the actual LED brightness decay cycle led shell, such as most of the UR for automotive taillights lit red tube more than a dozen to a few hours later, the brightness is only half of the original. Brightness decay cycle and LED production process has a lot of material, generally in the case of economic conditions permit should choose brightness decay slower four elements LED. Shell led the electrical 24w_led housing _ Jing Jing is provided by the Electrical Equipment Co., Ltd. Jinan. Jinan Jing Yue Electrical Equipment Co., Ltd.
