light source directly exposed to the outer edge of the lamps and lanterns, no glare prevention measures, sitting in the back of the students did a lot of glare, and low efficiency of lamps and lanterns, the desk surface illumination can not meet the requirements of current standards.
The blackboard now in order to meet the needs of the intensity of illumination and uniformity of lamps and lanterns, many with double light source of lamps and lanterns, side by side to install three light lamps and lanterns to the blackboard.

2.
The classroom after modification, the whole classroom power is 414 w, the power density of about 5.
