Description
Technical field
The present invention relates to a kind of lamps and lanterns, and in particular to the blackboard lights above a kind of blackboard being installed in teaching classroom.
Background technology
Classroom blackboard illumination purpose is to provide good vision luminous environment, to ensure that Faculty and Students can be easily black
Write on plate, read content on blackboard.In China, learning time length, the intensity of students in middle and primary schools is big, and is in physical development
Stage, the quality of lighting environment can directly have a huge impact student eyesight.Lighting environment is poor, and light moves towards poor, easily
Visual fatigue is caused, reduces learning efficiency, or even cause visual impairment.In fact, students in middle and primary schools' ratio of domestic myopia is high at present
Up to 80%, although the reason for causing such result is many, but also more or less have certain pass with the illumination condition in classroom
System.Therefore there is an urgent need for the light environment quality for improving students in middle and primary schools.And the place that classroom, which is student, mainly to be stopped, learn,
Classroom is the place of teachers ' teaching again at the same time, and the luminous environment in classroom stands in the breach the place for exactly needing to improve, for this usually
One assist illuminator is installed in the top of classroom blackboard to improve the luminous environment of classroom blackboard, to ensure that Faculty and Students can be light
The upper content of blackboard is write and read to loose ground on blackboard.This assisted illuminating lamp is commonly referred to as blackboard lights, good blackboard
Lamp requires to ensure the high illumination of vertical plane, good evenness and placement in place without producing uncomfortable dazzle, together
When preferably energy-saving lamp.
LED lamps are referred to as forth generation light source, have energy-saving and environmental protection, safety, long lifespan, low-power consumption, low-heat, high brightness,
The features such as waterproof, miniature, shockproof, light beam are concentrated, easy maintenance, can be widely applied to various instructions, display, decoration, backlight
The fields such as source, general lighting.Therefore also someone has invented LED blackboard lamps and lanterns at present, but finds that these LED blackboard lightses all do not have
Glare problem is solved well, has very detrimental effect to teachers ' teaching and student's study, therefore have impact on LED blackboard lightses
Extensive use.
The content of the invention
The main inventive purpose of the present invention, being to provide one kind can ensure that Faculty and Students at the same time can be easily well
Write on blackboard, read LED blackboard lights of the content without producing uncomfortable dazzle on blackboard.
Technical solution used in the present invention is：A kind of blackboard lights, including lamp housing, the end cap being connected with lamp housing both ends, and
From the high to Low LED lamp panel being installed in lamp housing, lens.Diffuser plate and grid bar assembly have been further included in lamp housing.Grille strip group
Part includes the grids of some front and rear trends and the forward and backward fixed strip of grid of left and right trend, and the front and back end of each grid is respectively and grid
