Power LED drivers | Arduino The design of this LED driver is very simple and probably can be found in many variations on the interenet: T2 operates in linear mode and acts as a variable resistor that controls the current through the LED’s. R1 pulls-up the gate of T2 so that T2 start
人因科技, LED雙電源行動摺疊檯燈 型號 HZ-8018, 再次讓人失望 | xiaolabaDIY http://wp.me/ph3BR-Tq 雖然不可以用垃圾來形容, 不過呢, 已經差不多了. 總耗電3W以上… ... 比對完畢, 當然是憑一己之力, 想辦法用簡易的方法, 把這樣不必要的浪費改到正途, 最少儘量減少無謂的發熱, 節省電池消耗而提供最長時間的點亮, 待續….
Using ShiftPWM to control 350mA high power LED’s with Arduino | ElcoJacobs.com Power supply The current of a few 3W RGB LED’s quickly adds up to huge supply current. 8 LED’s will require 8.4A (8x3x350mA). You need a beefy power supply and thick wires. A computer power supply and at least 1.5 mm 2 wire works well. The drivers are ...
