Description
Technical field
The utility model belongs to ligthing paraphernalia technical field, is specifically related to a kind of regulation reflecting surface height to adjust brightness
Light fixture.
Background technology
The most frequently used light regulative mode is to adjust output current size to control light source strong and weak in the prior art, light modulation
Mode uses switch-mode regulation more.
Utility model content
The purpose of this utility model is to provide a kind of regulation reflecting surface height to adjust the light fixture of brightness, is that one kind can be just
The light fixture of dimming mode prompt, directly perceived and interesting, by the height of regulating lampshade, the amount of reflecting light can be changed, adjusted with reaching
The purpose of whole brightness.
The utility model is that technical scheme is as follows used by reaching above-mentioned purpose：
A kind of regulation reflecting surface height is provided to adjust the light fixture of brightness, including housing, lampshade and light source, the housing
Upper end open, light source are arranged in the housing in opening, and the bottom of the lampshade is provided with a screw rod, inner bottom surface in the housing
A screw being engaged with screw rod is provided with, lampshade is rotated by screw rod to adjust height, is reflecting surface in the lower surface of lampshade.
Install reflector additional below lampshade and form reflecting surface, the light of enclosure interior light source is reflexed into surrounding, passes through tune
The height of lampshade is saved, the amount for reflecting light can be changed, to reach the purpose of regulation brightness.Meanwhile the light of reflection can also have
Effect reduces the dazzle of light source, makes light softer, protect eyes.
The mode of regulating lampshade is to adjust height, the Stability Analysis of Structures of screw rod by the rotation of screw rod in the technical scheme
Property is higher, and structure is also simple, it is easy to accomplish.Can additionally the conventional means such as line slideway, expansion link be used to realize, can
Complete the high and low position regulation of lampshade.
In one embodiment of above-mentioned technical proposal, the master control borad of driving light source is additionally provided with the housing and is gathered
Light cup, the light that the prefocus cup can send light source are converged and projected on reflecting surface.
In one embodiment of above-mentioned technical proposal, it is characterised in that described light source is LED lamp bead, and LED lamp bead is set
It is placed on master control borad, master control borad is fixedly mounted on housing.
In one embodiment of above-mentioned technical proposal, it is characterised in that described light source is two to eight, with screw
Centered on circumferentially uniformly arrangement.
In one embodiment of above-mentioned technical proposal, it is characterised in that the reflecting surface of the lampshade is circular cone reflecting surface
Or circular cone reflecting surface or spherical reflective surface.
In one embodiment of above-mentioned technical proposal, it is characterised in that be additionally provided with the housing power interface and
Switch.

Be provided with a screw 101 being engaged with screw rod, the internal thread of screw matches with external screw thread, the external screw thread on screw rod 201 with it is interior
Screw thread coordinates rotation, lampshade is freely moved up and down, and lampshade is rotated by screw rod to adjust height, is in the lower surface of lampshade
The reflecting surface 202 of circular cone.
Reflecting surface below lampshade is realized by installing reflector additional, and the light of enclosure interior light source is reflexed into four
In week, by the height of regulating lampshade, the amount for reflecting light can be changed, to reach the purpose of regulation brightness.Meanwhile the light of reflection
Line also can effectively reduce the dazzle of light source, make light softer, protect eyes.
Light source 401 uses LED lamp bead, LED lamp bead is arranged on master control borad 402, master control borad is fixedly mounted on housing.
Prefocus cup is additionally provided with LED lamp bead, the light that prefocus cup can send LED lamp bead is converged in smaller angular range and projected
On reflecting surface.LED lamp bead is four, the circumferentially uniformly arrangement centered on screw.
Power interface 403 and switch 404 are additionally provided with housing, power interface external power supply is powered to light fixture, switch control
The break-make of power supply, master control borad control LED lamp bead light.
Above example, it is only the preferable embodiment of the present invention, but protection scope of the present invention is not limited to
This, any one skilled in the art the invention discloses technical scope in, the change that can readily occur in or replace
Change, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection of claims
Scope is defined.
