Abstract
The utility model discloses a kind of desk lamps for improving the hot spot uniformity, including lamp holder, support frame and lighting device, lamp holder is equipped with switch, the bottom end of support frame is connect with lamp holder, lighting device is slidably connected on the support frame by carriage, lighting device includes lampshade, horn-like support ring and wiring board are provided in lampshade, wiring board is equipped with the LED of more composition annular array of light sources, each LED is located at the outside of horn-like support ring, reflector plate is posted on the inner wall of lampshade and on the outer wall of horn-like support ring, the opening of lampshade is equipped with diffuser plate.The light that LED is issued is emitted after reflector plate reflects, it is incident in diffuser plate at a certain angle, light is irradiated in certain area after the diffusion of diffuser plate by certain space proportion, the hot spot being consequently formed in the region uniformity with higher, thus reduce because hot spot unevenly caused by user's eyes discomfort and scatterbrained influence.
Description
Technical field
The utility model relates to lamp lighting technical field, in particular to a kind of desk lamp for improving the hot spot uniformity.
Background technique
The hot spot uniformity of the existing desk lamp within the scope of illumination region R500mm is poor, is concentrated with ratio to the attention of user
Significantly negative effect causes user to generate asthenopia and is easy to cause the visual impairment of user for a long time.Cause
This, it would be highly desirable to a kind of desk lamp that can improve the hot spot uniformity is developed, to improve attention centrality of the people using desk lamp when
Occur with the case where reducing visual impairment.
Utility model content
The purpose of this utility model is to provide a kind of desk lamps for improving the hot spot uniformity, when improving people using desk lamp
Attention centrality and reduce visual impairment the case where occur.
Used technical solution to solve above-mentioned technical problem: a kind of desk lamp improving the hot spot uniformity, including lamp holder,
Support frame and lighting device, the lamp holder are equipped with switch, and the bottom end of support frame as described above is connect with lamp holder, and the lighting device is logical
It crosses a carriage to be slidably connected on the support frame, the lighting device includes lampshade, and horn-like branch is provided in the lampshade
Pushing out ring and wiring board, the wiring board are equipped with the LED of more composition annular array of light sources, and each LED is located at horn-like branch
Reflector plate, the opening of the lampshade are posted on the inner wall of the lampshade and on the outer wall of horn-like support ring in the outside of pushing out ring
Diffuser plate is installed.
Further, the LED is adopting surface mounted LED.
Further, the horn-like support ring and wiring board are connected by a snap and are fixed on lampshade.
The utility model has the advantages that the light that LED is issued is by lampshade inner wall and on horn-like support ring outer wall in the utility model
Reflector plate reflection after be emitted, the light of outgoing is incident in diffuser plate at an angle, light pass through diffuser plate diffusion
It is irradiated to afterwards by certain space proportion in certain region, the hot spot being consequently formed in the region uniformity with higher,
It unevenly brings the discomfort of user's eyes to reduce hot spot and causes user to pay attention to because hot spot is uneven
The influence that power is not concentrated.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawings and examples:
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of lighting device in the utility model.
Specific embodiment
Referring to Figures 1 and 2, the utility model is a kind of desk lamp for improving the hot spot uniformity, including lamp holder 1,2 and of support frame
Lighting device 3, the lamp holder 1 are equipped with switch 5, and the bottom end of support frame as described above 2 is connect with lamp holder 1, and the lighting device 3 passes through
One carriage 4 is slidably connected on support frame 2, and the lighting device 3 includes lampshade 6, is provided in the lampshade 6 horn-like
Support ring 7 and wiring board 8, the wiring board 8 are equipped with the LED9 of more composition annular array of light sources, and each LED9 is located at loudspeaker
Reflector plate 10 is posted on the inner wall of the lampshade 6 and on the outer wall of horn-like support ring 7 in the outside of shape support ring 7, described
The opening of lampshade 6 is equipped with diffuser plate 11.
The light that each LED9 is issued is by the reflector plate on 6 inner wall of lampshade and on horn-like 7 outer wall of support ring
It is emitted after reflection, the light shape after outgoing, which has a certain degree, to be incident in the diffuser plate 11, and light passes through the diffuser plate
It is emitted after 11 diffusions, the light after outgoing is irradiated in certain region by certain space proportion, is consequently formed in the region
The hot spot uniformity with higher, in addition, the diffuser plate 11 will also have the function of reduce dazzle.User can also pass through
The carriage 4 adjusts the height of the lighting device 3, realizes the purpose of the fine tuning hot spot uniformity with this.This is practical new
Type replaces traditional structure shiny surface as light-configuration mode by using reflector plate 10, and the spatial distribution of light is adjusted with this,
The uniformity of hot spot is further improved while realizing normal illumination, reduces and brings user's eyes because hot spot is uneven
Discomfort, and reduce hot spot unevenly and lead to the scatterbrained influence of user.
Preferably, the LED9 is adopting surface mounted LED to one kind as the utility model.Adopting surface mounted LED passes through surface mount skill
Art is attached on the wiring board 8, and adopting surface mounted LED is conducive to reduce the thickness of the lighting device 3, to mitigate entire desk lamp
Weight, energy conservation and environmental protection.
Preferably, the horn-like support ring 7 and wiring board 8 are connected by a snap and are fixed on one kind as the utility model
On lampshade 6.The fixed form snapped connection not only good fixing effect, is also convenient for assembling the lighting device 3, is conducive to improve life
Produce efficiency.
It in process of production, can also be by changing tilt angle, the lampshade 6 of horn-like 7 outer wall of support ring
Spacing or 6 inner wall of the lampshade between the tilt angle of inner wall, horn-like 7 outer wall of support ring and each LED9 and each
Spacing between the LED9 obtains a variety of hot spot uniformitys, to be applied to a variety of workplaces.Simultaneously, additionally it is possible to pass through patch
The reflector plate of different surfaces attribute is attached to meet different uniformity of illuminance requirements, reduces time of adjustment structural plane attribute
Number is conducive to improve efficiency of research and development and production efficiency.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
