Type, manufacturing process is simple, and helps to radiate；Lamp body is diamond structure, and LED light source can be hidden in the rear panel of lamp body behind
On, it not can be appreciated that LED light source with respect to the student in front of blackboard lights, it is not only beautiful, and reduce dazzle；In addition, light barrier is set
Putting can be reflected into light on blackboard, make the light-receiving area of blackboard evenly, and can prevent dazzle.
As an improvement, the light barrier is arc panel, the angle between light barrier and rear panel is acute angle, light barrier and bottom
Angle between plate is obtuse angle.
As an improvement, being equipped with the first sliding groove and second sliding slot in the light trough, the LED light source includes LED substrate, setting
LED chip in LED substrate and the lens for light distribution, the LED substrate are slidedly assemblied in the first sliding groove, the lens
Both sides be equipped with sliding block, the sliding block is slidedly assemblied in second sliding slot.
As an improvement, the lens include the plane of incidence and exit facet, the exit facet is horizontal plane, and the plane of incidence is
Inclined surface.
As an improvement, being equipped with partition board between the top plate and bottom plate, space in lamp body is separated into front chamber with after by partition board
Chamber, the driving circuit of LED light source are arranged in front chamber, and the light trough is arranged in rear chamber.
As an improvement, the both ends of the lamp body are equipped with end cap.
As an improvement, the top plate is equipped with third sliding slot, the lower end of sunpender is hinged by hinged seat and lamp body, the hinge
Joint chair is with third sliding slot to be slidably matched.
As an improvement, the top plate is equipped with wireless control box.
As an improvement, corresponded on the third sliding slot at sunpender be equipped with cable-through hole, the sunpender be hollow structure, the mistake
String holes forms wire casing with sunpender.
Caused advantageous effect is the utility model compared with prior art：
The lamp body of the utility model is aluminium alloy one drawing and forming, and manufacturing process is simple, and helps to radiate；Lamp body is
Diamond structure, LED light source can be hidden on the rear panel of lamp body behind, and LED light is not can be appreciated that with respect to the student in front of blackboard lights
Source, it is not only beautiful, and reduce dazzle；In addition, light can be reflected on blackboard by the setting of light barrier, make the light of blackboard
Area evenly, and can prevent dazzle.
