High Power Heat Sink Is Not Just About Increasing Size (I)

      Comparing with traditional light source, LED chips have the advantages of long lifetime, quick response, high light efficiency and environment friendly. However LED Lights like  led high bay    have the general technical problem of heat dissipation. Without outstanding heat dissipation ability, the chip will have light decay due to undissipated heat which will further affect product lifetime.LED gives light by electron transitions through energy band. It doesn’t contain infrared ray in the spectrum. The heat of LED cannot be radiated, therefore it's called cold light source.
