The integration of heat conduction and heat dissipation, the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp shell is to reduce the working temperature of the LED chip, because the expansion coefficient of the LED chip and the expansion coefficient of the commonly used metal heat conduction and heat dissipation materials is very big, the LED chip can not be directly welded, so as not to damage the LED chip by high and low temperature thermal stress.

However, when using CCD photographic imaging, such as mobile phone shooting, because of the different sampling frequency, there will be water ripples. This simple test method has certain basis but is not rigorous. Severe stroboscopic damage is not only harmful to the eyes, but can even induce seizures! So we're still looking for Dachang. Finally, let's talk about what kind of light source is used for eye protection table lamp. We all know it but may not realize that the most eye protection light source is actually "incandescent lamp".
