A kind of lighting lamp of band venetial blind
Technical field
This utility model relates to field of LED illumination, more specifically, relates to the lighting lamp of a kind of band venetial blind for read-write operation.
Background technology
Most of LED illumination desk lamps of prior art can only be used as general lighting or floor light, and cannot function as reading and writing the photoptometry performances such as operation illumination use, i.e. illumination, the uniformity and light-proofness and can not meet the related request of national standard " read-write operation post lamp behaviour requires " (GB/T 9473-2008).
Although major part LED desk lamp local illumination can reach to read and write the requirement of operation illumination, but range of exposures is little, or irradiation area utilization rate is the highest, and uniformity of illuminance is the best, causes light source to waste.Existing LED desk lamp is in order to improve the utilization rate of range of exposures, it is designed as the turnover form of lamp body, irradiating angle by upset regulation lamp body, irradiation area can be changed along with the variation of read-write job position, but regulate range of exposures by upset lamp body to will result in user and see light source or reflector inwall in normal operation position, cause light-proofness not to be up to state standards, cause dazzling, human eye is had certain infringement.
Utility model content
In view of the read-write operation desk lamp of prior art is just like upper described shortcoming, this utility model provides the lighting lamp of a kind of band venetial blind, which solve existing read-write operation lighting lamp illumination, all with degree, the problem such as light-proofness is the best, national standard " read-write operation post lamp behaviour requires " (GB/T 9473-2008) related request can be met, and light source is fully used, easy to use.
The scheme that this utility model is used by its technical problem of solution is:
The lighting lamp of a kind of band venetial blind is provided, support arm including lamp socket, lamp body and connection lamp socket Yu lamp body, described lamp body is rotationally connected with support arm, lamp design is for spinning upside down, and described lamp body includes LED diffusion sheet, LED shade, lampshade lower cover, LED lamp panel and the lampshade upper cover being sequentially connected with from bottom to top;Described LED shade is respectively provided on two sides with a piece of LED window-blind, described LED shade is flexibly connected with LED window-blind, and two be provided with linkage structure between LED window-blind, when overturning lamp body and making LED lamp panel rotate towards a side, the LED window-blind of a nearlyer side is towards rotating in same direction, and the LED window-blind of a side is towards rotating backward farther out.Make light can not from window-blind inner reflection, user can't see light source and reflection light, it is to avoid user is dazzling.This patent is by the irradiating angle of upset regulation lamp body, irradiation area can be changed along with the variation of read-write job position, and the setting of venetial blind simultaneously overcomes upset lamp body and causes user to see light source or the drawback of reflector inwall in normal operation position.
Further, described LED diffusion sheet, LED shade, lampshade lower cover, LED lamp panel and lampshade upper cover nested encryptions the most successively.
Further, the linkage structure between described LED window-blind uses gear and tooth bar physical connection so that while upset lamp body, LED window-blind meeting adjusted in concert angle, thus realizes shade function.
Further, the exiting surface of described LED diffusion sheet is parallel with LED lamp panel, improves out the uniformity of light.
Further, described support arm is connected by the first rotating connector with lampshade upper cover.Described first rotating connector includes the first rotating shaft and the second rotating shaft laying respectively at the first rotating connector two ends, and described first rotating shaft is orthogonal with the second rotating shaft.
Further, described support arm and the first rotating connector are connected by the first rotating shaft, it is achieved the pitch rotation of the first rotating connector.
Further, described lampshade upper cover and the first rotating connector are connected by the second rotating shaft, it is achieved spinning upside down of lampshade upper cover.
Further, described support arm is connected by the second rotating connector with lamp socket, the rotating shaft of described second rotating connector and the first shaft parallel of the first rotating connector, it is achieved swinging of support arm.
The beneficial effects of the utility model are: this patent is by the irradiating angle of upset regulation lamp body, irradiation area can be changed along with the variation of read-write job position, and the setting of venetial blind simultaneously overcomes upset lamp body and causes user to see light source or the drawback of reflector inwall in normal operation position.Make full use of light source, make the light-proofness of desk lamp be up to state standards while increasing operation rate, it is to avoid dazzling, reduce the light extent of damage to human eye.

Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is further described.Wherein, being merely cited for property of accompanying drawing illustrates, expression is only schematic diagram, rather than pictorial diagram, it is impossible to it is interpreted as the restriction to this patent;In order to of the present utility model embodiment is better described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product;It will be understood by those skilled in the art that some known features and explanation thereof may will be understood by omission in accompanying drawing.
As shown in Figure 1 to Figure 3, this patent provides the lighting lamp of a kind of band venetial blind, including lamp socket 100, lamp body 200 and the support arm 300 connecting lamp socket and lamp body, described lamp body 200 is rotationally connected with support arm 300, lamp body 200 is designed to spin upside down, and described lamp body 200 includes the LED diffusion sheet 210 of nested encryptions the most successively, LED shade 220, lampshade lower cover 230, LED lamp panel 240 and lampshade upper cover 250;Described LED shade 220 is respectively provided on two sides with a piece of LED window-blind 221, described LED shade 220 is flexibly connected with LED window-blind 221, and two be provided with linkage structure between LED window-blind 221, when overturning lamp body 200 and making LED lamp panel 240 rotate towards a side, the LED window-blind of a nearlyer side is towards rotating in same direction, and the LED window-blind of a side is towards rotating backward farther out.Make light can not from window-blind 221 inner reflection, user can't see light source and reflection light, it is to avoid user is dazzling.This patent is by the irradiating angle of upset regulation lamp body 200, irradiation area can be changed along with the variation of read-write job position, and the setting of venetial blind 221 simultaneously overcomes upset lamp body 200 and causes user to see light source or the drawback of reflector inwall in normal operation position.
Linkage structure between described LED window-blind uses gear and tooth bar physical connection so that while upset lamp body, LED window-blind meeting adjusted in concert angle, thus realizes shade function.
