Description
Technical field
It the utility model is related to lighting technical field, more particularly to a kind of control device for blackboard illumination.
Background technology
In school or workplace, for people generally with longer between at the moment, creating a good lighting environment can be with
Mitigate visual fatigue situation, improve the efficiency of study and work.The light fixture of illumination is divided into two classes：Workspace light fixture and blackboard area lamp
Tool, blackboard area light fixture is very special to the demand of luminous intensity distribution, because blackboard area light fixture needs the top installed in blackboard, is allowing blackboard
Illumination and the uniformity reach standard requirement while, can't give stand it is artificial into dazzle on dais.
At present, blackboard illumination is usually to be used in the upper of blackboard along two single tube fluorescent lamps of installation as blackboard lights, is equipped with
The asymmetric reflector of luminous intensity distribution, light output is set to become more rationally, also one kind is to use LED to improve lamp as light source
Has efficiency.But the shortcomings that both blackboard lightses, is：Installation site is relatively fixed, its range difference to the upper and lower edge of blackboard
It is different larger；Luminous flux is too low, and vertical illumination is less than whole average level brightness value and uniformity extreme difference, causes to listen speaker not see
Content on Chu's blackboard, local reflex light are directly mapped to the eyes of people, and the dazzle serious interference to speaker.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is that providing a kind of blackboard that is used for illuminates
Control device, illumination is high, good evenness, can eliminate dazzle, be widely used in the regions such as classroom, meeting room, classroom.
The utility model is achieved through the following technical solutions：
A kind of control device for blackboard illumination, including principal mode material shell, the driving for being arranged at principal mode material enclosure
Power supply, the plug for being arranged at principal mode material shell both ends, the side cover being arranged at outside plug, the principal mode material shell include groove surface and
Burnishing surface, the groove surface is interior to set PCB lamp board, and lens are provided with above PCB lamp board, are burnishing surface on the outside of the lens, interior
Side is provided with lug boss, and both sides are provided with holding section.
The lens change PCB lamp board lighting angle, and meet type unified glare value UGR<19.
The PCB lamp board is provided with multiple spaced LEDs.
Also include the suspension rod for being arranged at the burnishing surface of principal mode material shell, the suspension rod Extensible.
The beneficial effects of the present invention are:
By the way that PCB lamp board and driving power are built in principal mode material shell, reach effect more smooth, integrated in appearance
Fruit；
The lighting angle of light can effectively be changed by being covered in the lens lug boss of PCB lamp board, in irradiation area
Light is more uniform, reduces type unified glare value UGR, the holding section of lens makes lens be movably fastened on principal mode material shell；
The design of telescopic suspension rod makes easier for installation, reduces it to the distance difference on the upper and lower edge of blackboard.
Brief description of the drawings

Fig. 2 is decomposition texture schematic diagram of the present utility model
Fig. 3 is sectional view of the present utility model
Embodiment
In order that technical problem, technical scheme and beneficial effect that the utility model solves are more clearly understood, below
In conjunction with the embodiments, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only
To explain the utility model, it is not used to limit the utility model.
As shown in Figure 1 and Figure 2, the utility model includes principal mode material shell 1, driving power 2, PCB lamp board 3, lens 4, plug
5th, side cover 6, suspension rod 7, principal mode material shell 1 include groove 101 and burnishing surface 102, and driving power 2 is arranged in principal mode material shell 1
Portion, PCB lamp board 3 are arranged in the groove 101 of principal mode material shell 1, and lens 4 are covered in the top of PCB lamp board 3, in the He of PCB lamp board 3
The both ends of lens 4 are respectively equipped with plug 5, are respectively equipped with side cover 6 outside plug 5, pass through plug 5 and the fixed closed principal mode material of side cover 6
The inner part of shell 1, reaches product whole structure, and suspension rod 7 is arranged at the burnishing surface 102 of principal mode material shell 1.
The Extensible of suspension rod 7, according to blackboard height, flexibly change setting height(from bottom), by hanger erection in ceiling,
Reduce it to the distance difference on the upper and lower edge of blackboard.
As shown in figure 3, PCB lamp board is fastened in groove 101, the face PCB lamp board of lens 4 is fastened on groove port, the face of lens 4
There is lug boss 401 to the side of lamp plate, both sides are provided with holding section 402, and outside is smooth, and lens 4 are sent out by changing PCB lamp board 3
Angular, light uniform irradiation is set to meet type unified glare value UGR on blackboard and reducing type unified glare value UGR<19.
PCB lamp board 3 is provided with multiple spaced LEDs 301, and LED light fixture is more efficient, more saves.
Preferred embodiment of the present utility model is the foregoing is only, not to limit the utility model, therefore, only
This is should be included in all any modification, equivalent and improvement that the utility model specification and drawings content is made etc.
Within the protection domain of utility model.
