Product overview
The JIUSI JS-SD-045 is an aircraft-mounted searchlight accessory for multirotor UAV integration. Its aluminum-alloy body contains an integrated high-power LED emitter, a dual-lens optical arrangement and a temperature-controlled cooling fan. A high-precision, high-torque servo provides 90° pitch control for directing illumination. The optical assembly combines an initial filtering and light-collection stage with a tempered-glass second lens. Yellow, white and blue light selections provide different illumination options, with three brightness levels available for each color.
Integration requires space for a 128mm-long, 116mm-wide and 200mm-high assembly weighing 1080g. The light accepts 28-80V input, has a specified power of 45W, and uses a TX60 power connector plus a PWM signal cable. Quick-release mounting is supported. Remote control depends on connection to the aircraft-side data link, with control distance tied to the aircraft's flight distance. The operating temperature range is -20°C to 50°C. The cooling fan starts automatically as lamp temperature rises during extended operation; it remains stopped at initial startup.
