3. High standard surface roughness
Undoubtedly, the surface roughness of the bearing race affects the lubrication effect, and the effectiveness of the lubrication directly determines the life of the bearing. In Fig. 4, the degree of contact friction between the metals is different under the same calculated oil film thickness, and the resulting bearing damage is different. Under the same working conditions, we use different bearing roughness bearings for comparison test, as seen in Figure 5, as the working conditions become more and more severe, l (calculated oil film thickness and composite roller raceway surface roughness ratio) More and more hours, the enhanced high standard surface roughness design bearing and ordinary bearing life can be even up to 4 times.

For this Blue SMD LED, we can package with single chip 3528 SMD LED or 2 chips 3528 SMD LED , and the power can be 0.1W 3528 blue SMD LED, 0.06W 3528 blue SMD LED, 0.2W 3528 blue SMD LED, 0.5W 3528 blue SMD LED and so on.
3528 blue SMD LED is deeply loved by their users because of the small size and the high bightness.
It is often used in LED lighting, LED Lamps, LED backlight, LED panel lights, LED furniture, grow light LED, fill light LED, LED aperture and other lighting products.
In this catalog, we mainly introduce the 3528 blue SMD LED.
The voltage of the 3528 blue SMD LED is between 2.8-3.5V.
