Hello,
I am new to this forum as a member but have read it for a while and discovered many good ideas from different users.
I am planning to develop a high power searchlight with short arc lamp, remote controlled from a joystick through a pan/tilt gir. The searchlight shall be marine grade for outdoor use, compact size and the drum shall be made of seawater resistant aluminium for good heat management. I have decided to use a HMI 1200W/SE metal halide lamp with a hot-restrike ignitor combined with a 12" deep-dish parabolic glass reflector with short focal distance. The focusing system shall also be remote controlled from the control panel through a servo motor inside searchlight drum so it will be possible to switch between wide and narrow beam. Searchlight shall be operational in a range of +/- 175 degrees in horizontal direction and +/- 30 degrees in vertical direction from the pan/tilt gear. Speed apx. 15-20 degrees/sec. horizontal and apx. 5-6 degrees/sec. in vertical direction. The lamp shall be cooled by an internal forced air cooling system circulating air internally inside the drum, managing the heat.
I will start with the design of the searchlight drum. When the drum is completed and all internal parts have been fitted, it is time to proceed with the remote controlled pan/tilt gearbox.
I will update with pictures here as the project progress forward. I expect a design and production time for apx. 2-3 months from now for my prototype.
