Abstract
The utility model discloses a kind of lampshade structure of adjustable illuminator position, comprise arc lampshade, also comprise an outer surface and be provided with externally threaded hollow circular cylinder, the opening that its one end is provided with through lampshade bottom is connected with illuminator, what hollow circular cylinder outer sheathed was fixed with its matching rotation establishes female nut, and nut is fixed on the outer surface of the opening part that lampshade bottom is provided with.The utility model structure is simple, can arbitrarily adjust illuminator position, the reflection angle of illuminator and reflector curved reflecting surface also can change thereupon, forms different reflection angles, and then change irradiating angle, can arbitrarily change as light-focusing type or floodlight type radiation response.
Description
Technical field
The utility model relates to a kind of lampshade structure of adjustable illuminator position.
Background technology
Existing lampshade structure has fixed illuminator position when designing and producing, so range of exposures and function are fixed, when lighting apparatus setting height(from bottom) lower (irradiation distance is shorter), range of exposures can be smaller, light is too concentrated, affects radiation response.When lighting apparatus setting height(from bottom) higher (irradiation distance is distant), range of exposures is larger, and light too disperses, and radiation response is low, so will limit to lighting apparatus operating altitude range (limitation irradiation distance), affect the popularity of equipment use.
Utility model content
In order to solve the problems referred to above that prior art exists, the purpose of this utility model is the lampshade structure proposing a kind of adjustable illuminator position.
For achieving the above object, the utility model is solved by following technical scheme:
A kind of lampshade structure of adjustable illuminator position, comprise arc lampshade, also comprise an outer surface and be provided with externally threaded hollow circular cylinder, the opening that its one end is provided with through described lampshade bottom is connected with described illuminator, what described hollow circular cylinder outer sheathed was fixed with its matching rotation establishes female nut, and described nut is fixed on the outer surface of the opening part that described arc lampshade bottom is provided with.
As optimal technical scheme, the opening diameter sizableness that described hollow circuit cylinder body diameter and described arc lampshade bottom are provided with.
As optimal technical scheme, the curved reflecting surface of described arc lampshade is evenly provided with the convex grain of reflection, and described convex grain is spherical arc structure.
As optimal technical scheme, described arc lampshade one end is open end, the other end and bottom end, and its described opening be provided with is closed by described hollow circular cylinder and nut.
As optimal technical scheme, the total length of described hollow circular cylinder and described illuminator is no more than the total depth of described arc lampshade.
Owing to adopting above technical scheme, the lampshade structure of a kind of adjustable illuminator position of the present utility model, when left rotation and right rotation nut, hollow circular cylinder can move up and down, and changes illuminator height and position, when illuminator position is moved simultaneously, the reflection angle of illuminator and reflector curved reflecting surface also can change thereupon, form different reflection angles, and then change irradiating angle, can arbitrarily change as light-focusing type or floodlight type radiation response; And the convex grain of sphere that the curved reflecting surface of reflector is provided with, the light reflection that illuminator irradiates can be gone out more, larger angle, form reverberation widely, allow illuminating effect evenly.

Detailed description of the invention
Below with reference to the accompanying drawings and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, a kind of lampshade structure of adjustable illuminator position, comprise arc lampshade 1, also comprise an outer surface and be provided with externally threaded hollow circular cylinder 3, the opening that its one end is provided with through lampshade bottom is connected with illuminator 5, and what hollow circular cylinder 3 outer sheathed was fixed with its matching rotation establishes female nut 2, and nut 2 is fixed on the outer surface of the opening part that lampshade bottom is provided with, the curved reflecting surface of arc lampshade is evenly provided with the convex grain 4 of reflection, and it is spherical arc structure.
The opening diameter sizableness that hollow circular cylinder 3 external diameter and arc lampshade bottom are provided with, this hollow circular cylinder 3 coordinates with nut 2 makes this closure of openings, and the other end of arc lampshade is open end.Hollow circular cylinder 3 adds that the total length of illuminator 5 is no more than the total depth of arc lampshade, and the illuminator 5 namely after adjustment can not exceed the outer rim of arc lampshade 1 light-emitting window.
When rotary nut 2, hollow circular cylinder 3 can move up and down, change illuminator 5 position simultaneously, when illuminator 5 position is moved, illuminator 5 also can change with the reflection angle of reflector 1 curved reflecting surface thereupon, forms different reflection angles, and then changes irradiating angle, can arbitrarily change as light-focusing type or floodlight type radiation response, as shown in Fig. 2-1 and 2-2 (in figure, 6 represent light range of exposures line).
But above-mentioned detailed description of the invention is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
