Consistent Illumination Uniformity 2835 Protect Eyes For Backboard Lamp

 

Application Introduction:

 

Blackboard lamp is a special lamp for blackboard area lighting in the classroom. It is different from the lamps and lanterns on the seats in the classroom. The reflector adopts a special angle design. Its light distribution curve is laterally asymmetric, and the vertical illumination is high, which evenly illuminates the blackboard surface. When asking, when the projection direction of the blackboard lamp is 55 °, the shading angle is more than 45 °, so that students can watch the blackboard without direct glare interference and take care of their eyes.

Packaging:

 

Consistent Illumination Uniformity 2835 Protect Eyes For Backboard Lamp 2

Cautions:

The encapsulated material of the LEDs is silicone. Therefore the LEDs have a soft surface on the

Top of package. The pressure to the top surface will be influence to the reliability of the LEDs. Precautions Should be taken to avoid the strong pressure on the encapsulated part. So when use the picking up nozzle,The pressure on the silicone resin should be proper.

Soldering iron:

   When hand soldering, the temperature of the iron must less than 300℃ for 3 seconds.

   The hand solder should be done only one times

SMT Reflow Soldering Instructions SMT:

   Reflow soldering should not be done more than two times ;

   When soldering , do not put stress on the LEDs during heating ;

   The recommended reflow soldering profile as following ;
