The utility model content
The purpose of this utility model is to provide a kind of searchlight, and in order to solve, in prior art, the light utilization efficiency of searchlight is low, the life-span is short and searchlight hot spot size can not be adjusted as required, thereby limits the problem of its use.
For addressing the above problem,
A kind of searchlight, comprise drive control box, for driving and control described searchlight; Shell, be connected with described drive control box;
Also comprise the heat conduction support be fixedly connected with described shell;
Be arranged on the light source on described heat conduction support;
Be arranged on described enclosure the reflection shield relative with described light source, described reflection shield is connected with described heat conduction support by guide rail or telescopic bar, and the distance of described reflection shield and described light source is adjustable;
Governor motion, described governor motion is fixedly installed on described drive control box, and the free end of described governor motion is fixedly connected with described reflection shield, the distance of described governor motion for regulating described reflection shield and described light source.
Preferably, described reflection shield is dome-type.Reflection shield is that dome-type can better be concentrated the outgoing beam of light source, to obtain larger light intensity.
Preferably, described governor motion is leading screw, and the adjusting portion of described leading screw is exposed at described drive control box outside, and the free end of described leading screw is fixedly connected with described reflection shield through described drive control box.Adopt leading screw as the distance of regulating described reflection shield and described light source, simple in structure, be easy to realize, cost is low.
Preferably, described heat conduction support is fixedly connected with described shell by the heat conduction circle, and described heat conduction circle is fixedly connected with described shell, and described heat conduction support is fixedly connected with described heat conduction circle.This arranges the radiating effect that can increase the utility model searchlight.
Further preferred, described shell is thermal conductive shell.Shell is thermal conductive shell, and the dissipation of heat that derives from described light source on the heat conduction circle that is easy to be fixedly connected with described shell, to nature, increases the life-span of the utility model searchlight.
As preferably, described light source is the LED lamp.LED streetlamp energy-saving, long service life, environmental protection.
Preferably, also be provided with the translucent cover of the described light source of protection on described shell.
Searchlight of the present utility model, reflection shield is connected with described heat conduction support by guide rail or telescopic bar, makes the distance of described reflection shield and described light source to adjust; Simultaneously, reflection shield is fixedly connected with the free end of governor motion.Can adjust as required the distance of described reflection shield and described light source by governor motion.Whole beam projectings that light source sends, to the reflection shield of high reflecting rate, are regulated and are obtained high-brightness light and the size that can regulate as required hot spot by the luminous intensity distribution of reflection shield.
Projector light utilization rate of the present utility model is high, and has increased the tunable performance of irradiation area, makes searchlight practicality of the present utility model greatly strengthen.
