Zusammenfassung:	The utility model discloses a LED blackboard lamp, its structure include the outer frame of aluminium matter, LED light source, PCB circuit board, optical lens, reflection paper, glass veil. The inside recess that is equipped with of aluminium matter frame for fixed aluminium metal substrate and glass veil, LED light source weld on the PCB circuit board, on the said optical lens installation PCB circuit board, cover in LED light source top, there is reflection paper subsides in a frame lateral wall aluminium metal substrate top, and the glass dustcoat lies in whole optical system and outer and seal outer frame. The utility model provides a take the LED blackboard lamp of polarisation design, to the position characteristics of blackboard with lamps and lanterns, carry out the secondary optical design to the LED through optical lens, realize the illuminating effect of spotlight and polarisation, greatly improve the utilization ratio of light energy, keep the higher degree of consistency on the blackboard face simultaneously. The blackboard lamp simple structure has higher practicality simultaneously.
