Description
Technical field
A kind of LED clipboards lamp is the utility model is related to, especially a kind of asymmetric light distribution LED clipboard lamps, belongs to LED
Lamp technical field.
Background technology
Clipboard lamp on the market at present, the overwhelming majority are still to continue fluorescent tube to add the concept with cover base, and inside uses
Conventional fluorescent fluorescent tube or LED fluorescent tubes, outside use the base with cover.This design method exist three it is critically important the shortcomings that：
（1）Lamp luminescence angle is very big, although by the shading of lampshade, luminous energy wastes still very serious, writing plate surface reception
To luminous energy only account for small part；（2）Power of lamp tube is restricted, and can not increase power, i.e., can not improve clipboard table
Face illumination, usual clipboard surface illuminance are far below national requirements；（3）Dazzle is serious, and the light of central light strength is substantially under just
Side's irradiation, influences teacher's sight.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of LED clipboards lamp, Neng Gouyou
Effect improves the uniformity of illuminance of writing plate surface.
According to technical scheme provided by the utility model, the LED clipboards lamp, including section material framework, it is characterized in that：
The lower section of the section material framework is provided with linear mounting groove, LED light source module is fixed in linear mounting groove, in LED light source module
Light-emitting area set can change outgoing light direction, make uniform light be irradiated to writing plate surface upper and lower side rectilinear lens.
In a detailed embodiment, the linear mounting groove（7）Two side between shape it is at a certain angle.
In a detailed embodiment, the angle of the angle is arranged to 60-80 °.
In a detailed embodiment, the angle of the angle is arranged to 74 °.
In a detailed embodiment, the rectilinear lens is strip, each section all same of length direction.
In a detailed embodiment, power supply driver is installed in the inside of the section material framework, power supply driver leads to
Cross the inside that power supply fixed support is arranged on section material framework.
In a detailed embodiment, the outside of the section material framework sets power supply driver.
In a detailed embodiment, end cap is set at the both ends of the section material framework.
In a detailed embodiment, the fixed installation for being used for that light fixture to be fixedly mounted is provided with above the section material framework
Groove.
In a detailed embodiment, it is provided with the fixed installation groove for fixed connector.
The utility model has advantages below：
（1）Stabilization firm in structure of the present utility model, is distributed LED light source in linear mounting groove, can be in certain limit
Interior hoisting power, so as to improve the illumination and the uniformity at writing plate surface or so end；
（2）The utility model is emitted light direction by the optical grade structural change of rectilinear lens, ensures that most of light shines
Writing plate surface is mapped to, the uniformity of illuminance of writing plate surface upper and lower side is improved and eliminates shadow of the clipboard lamp to teacher's eyes
Ring.

Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, LED clipboards lamp described in the utility model includes section material framework 1, the section of section material framework 1
For ellipse, naturally it is also possible to other shapes are designed as, it is such as circular；Linear mounting groove is provided with the lower section of the section material framework 1
7, LED light source module 3 is fixed in linear mounting groove 7, makes the good appearance of clipboard lamp generous；In addition, the linear installation
Shape is at a certain angle between the two side of groove 7, and the angle could be arranged to 60-80 °, preferably 74 °；Pass through setting for the angle
Putting can be defined to the lighting angle of LED light source module 3, avoid the waste of luminous energy.
As shown in Fig. 2 the light-emitting area in the LED light source module 3 sets rectilinear lens 4, the rectilinear lens 4 is strip,
Rectilinear lens 4 uses high permeability PC materials, by rectilinear lens 4 to change the radiation direction through lens, is irradiated to light
Plate surface specified location is write, so as to ensure the uniformity of illuminance of whole writing plate surface top and the bottom.
As shown in Figure 1 and Figure 2, end cap 2 is set at the both ends of the section material framework 1, electricity is installed in the inside of section material framework 1
Source drive 5, power supply driver 5 are arranged on the inside of section material framework 1 by power supply fixed support 6.Of the present utility model another
In one embodiment, power supply driver 5 can be arranged on the outside of section material framework 1.
The section material framework 1 is made by aluminum alloy materials, has very strong heat-sinking capability and structural rigidity, lifts lamp
The overall performance of tool, surface can carry out plastic-spraying processing or oxidation processes as needed, have very high corrosion resistance and weatherability.
As shown in Figure 1 and Figure 2, the fixed installation groove 8 for light fixture to be fixedly mounted is left above the section material framework 1, spiral shell can be passed through
