Description
Technical field
The invention belongs to field of light fittings, specifically a kind of marine searchlight.
Background technology
Xenon lamp is also HID gas discharge type head lamps, and it is traditional with the high-pressure xenon replacement being wrapped in quartz ampoule
Tungsten filament, activates xenon using high-tension current and forms a branch of arclight, continuous discharge can light between electrodes.Xenon is produced
Raw white superpower arclight, can improve light color temperature value, send the sunshine in similar daytime, and this light is for raising night
And sight line definition has obvious effect in mist.In addition, xenon lamp does not have a filament, thus would not produce because filament is disconnected and
The problem scrapped, service life are much longer.Xenon lamp is because of its higher color temperature, the illumination more assembled and longer use longevity
Life, is just progressively being applied to searchlight field.
Searchlight is that bulb and reflector are adjusted to optimal spot condition to make luminous energy be irradiated to farthest distance, but very
Marine closely operation when many needs very big illuminance, lower powered xenon lamp meet illuminance requirement.Again because of sea
Upper bad environments, the degree of protection of marine searchlight need to reach more than IP66.In order to improve IP grades, existing marine searchlight
Often lamp cylinder is all-sealed, and this searchlight is poor because of heat dispersion, and powerful xenon lamp quantity of heat production is big, thus limits
The use of high-power xenon lamp is made.
In order to realize the free switching of remote focus irradiation and the irradiation of low coverage discrete light, existing searchlight is often through changing
Become position of the bulb in lamp cylinder and carry out zoom, but as xenon lamp can produce the high-tension electricity of volts up to ten thousand in just point bright light, and
Xe lamp bulb connects power supply, can bring great potential safety hazard to user using this zoom mode.
The content of the invention
The technical problem to be solved is：A kind of marine searchlight of zoom mode safety is provided.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of marine searchlight, including lamp cylinder,
Reflector, motor and movable supporting frame are provided with the lamp cylinder, the movable supporting frame includes ball screw, " L " shape connector,
Described " L " shape connector one end is fixed on the reflector bowl bottom, the other end and the ball screw of " L " the shape connector
Threaded connection, the motor are arranged on lamp cylinder bottom, and the ball screw is coaxially connected with the output shaft of motor.
The beneficial effects of the present invention is：" L " shape connector is controlled by the start and stop of motor relative with ball screw
The mobile relative position to change reflector, realizes safe zoom.
