High Color Rendering Index Comfortable Light 3v 0.2w 4800-5200k Spectrum Light
Application Introduction:
The angle is less than 16. Traditional fluorescent lamps or LED tubes are directly exposed and installed on the ceiling. The light is directly projected without any secondary optical design. When students sit in the classroom and look at the blackboard, the strong light of multiple tubes installed on the ceiling will be projected to the eyes (especially the students sitting in the middle and rear of the ceiling). After a long time, it will cause strong discomfort, produce blurred eyes, double shadows, and seriously affect vision fatigue, Over time, it causes great damage to vision. The eye protection lamp adopts the uniform diffusion of secondary optical light and grid optical design, and the light will not directly irradiate the eyes under vertical illumination.

Packaging:
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 ;
Product features:
Adopt good quality chip and frame ,antistatic good stability Ultra low attenuation
High brightness ,low attenuation high color rendering
Minimum 70,80,90 95 CRI options
