Abstract
The utility model discloses a lamp with adjustable illumination effect, which includes a light emitting assembly and a lampshade, wherein a first support framework is arranged on the light emitting assembly, the first support framework is coated by the lampshade, the lampshade comprises a second support framework and a covering film adhered onto the second support framework in a coating manner, the second support framework comprises a plurality of round rings distributed in parallel and support rods connecting the round rings, and a plurality of positioning parts matched with the first support framework are distributed along the support rods. The lamp has a simple structure and is convenient to use; through utilizing the cooperation of the positioning parts and mounting holes in different positions on the support rods, the lampshade can have position changes; and when the space defined by the lampshade and the upper surface of the light emitting assembly changes, the lamp has corresponding changes on illumination rang or illumination intensity.
Description
Technical field
The utility model relates to a kind of lighting apparatus, relates in particular to a kind of LED lamp, can adjust illuminating effect through the variation of lampshade position.
Background technology
The LED projecting lamp is widely used in lighting field, in order to change radiation direction, enlarges its illumination zone; Generally can on luminescence component, install lampshade additional, lampshade is made up of support frame and the overlay film that pastes on support frame, for fear of harmful effect such as dazzling grade; Described overlay film can adopt diffusion barrier; Diffusion barrier has the effect of diffusion light, and promptly light on its surface scattering can take place, and disseminates out uniformly with light is soft; The basic structure of most diffusion barriers is on transparent base, to be coated with optics astigmatism particle like the PET two sides.
But in the prior art, the light fixture of general structure is difficult to adjustment projection scope or illumination, must be by equipment complicated and specialty.
The utility model content
The utility model provides a kind of LED light fixture simple in structure, easy to use, can adjust illumination zone or illumination only through the change of lampshade position.
A kind of light fixture of adjusting illuminating effect; Comprise luminescence component and lampshade; Described luminescence component is provided with first support frame, and it is outside that described lampshade is wrapped in first support frame, and described lampshade is made up of second support frame and the overlay film that pastes on second support frame; Second support frame is made up of the annulus of some parallel distributions and the support bar that connects these annulus, is distributed with the positioning element that several match with first support frame along described support bar.
Described overlay film can adopt existing diffusion barrier, also can adopt existing other materials.
Described first support frame comprise bracing ring and be connected bracing ring and luminescence component between some connecting rods; Described bracing ring has installing hole; In the support bar of described second support frame, locating hole or the bolt of positioning element for matching with installing hole.
Utilize that the different positioning element in position matches with installing hole in the support bar, position that then can the conversion lampshade, the space that upper surface limited that is equivalent to increase or reduced lampshade and luminescence component.
The upper surface of described luminescence component is circular, is distributed with several LED light-emitting components.
Connecting rod in described first support frame is four, all perpendicular to the upper surface of luminescence component, and evenly distributes around the excircle of the upper surface of luminescence component.
Because second support frame is made up of the annulus of some parallel distributions and the support bar that connects these annulus; It is the equal of the frame structure of tubular; Therefore the overlay film of described lampshade is for only having the tubular of bottom opening, and the upper surface of described luminescence component gets into and be positioned at the overlay film of lampshade through this bottom opening.
Support bar in described second support frame is four, and the position is corresponding with described four connecting rods respectively.
The utility model fitting structure is simple, easy to use; Utilize that the different positioning element in position matches with installing hole in the support bar; Position that then can the conversion lampshade; When the space that upper surface limited of lampshade and luminescence component changed, the illumination zone of light fixture or illumination all can change accordingly.

The specific embodiment
Referring to accompanying drawing, a kind of light fixture of adjusting illuminating effect of the utility model comprises luminescence component and lampshade, and luminescence component has the housing 6 that is roughly tubular, and housing 6 bottom surfaces are equipped with base 5.The upper surface 7 of luminescence component has the LED that several rules distributes, and has drive circuit in the housing, is used to make LED luminous.
Luminescence component is provided with first support frame, and first support frame comprises bracing ring 8 and is connected the some connecting rods 9 between bracing ring 8 and the luminescence component, has some installing holes 10 around bracing ring 8.
It is outside that lampshade is wrapped in first support frame; Lampshade is made up of second support frame and the overlay film 1 that pastes on second support frame; Overlay film 1 is for only having the tubular of bottom opening, and the upper surface 7 of luminescence component gets into and be positioned at the overlay film 1 of lampshade through this bottom opening.
Second support frame is made up of the annulus 2 of some parallel distributions and the support bar 3 that connects these annulus 2, is distributed with the locating hole 4 that several match with installing hole 10 along support bar 3.
Connecting rod 9 in first support frame is four, all perpendicular to the upper surface 7 of luminescence component, and evenly distributes around the excircle of the upper surface 7 of luminescence component.Support bar 3 in second support frame is four, and the position is corresponding with four connecting rods 9 respectively.
Referring to Fig. 4～6 position of upper surface 7 of luminescence component (dotted line illustrated); Utilize that the different locating hole 4 in position matches with installing hole 10 in the support bar 3; Position that then can the conversion lampshade is equivalent to have increased or reduced the space that the upper surface 7 of lampshade and luminescence component is limited.
Because installing hole 10 is fixed with respect to the upper surface 7 of luminescence component, when position in the support bar 3 leaned on last locating hole 4 to match with installing hole 10, the space that the upper surface 7 of lampshade and luminescence component is limited was minimum; When position in the support bar 3 by under locating hole 4 when matching with installing hole 10, the space that the upper surface 7 of lampshade and luminescence component is limited is maximum; The illumination zone of light fixture or illumination all can change accordingly.Even can also lampshade be removed, utilize luminescence component to regard shot-light and use.
