With the development of LED chip technology and packaging technology, adapt to the demand of high luminous flux LED products in the field of lighting, this power type LED is gradually entering into the market. This type of power leds are generally put the light emitting chip on the cooling heat sink, the above assembly […]
LED luminous flux is an indicator of a whole luminance of the light source. Unit is LM (Lumen). Frequently used in the light source for luminance, it is refer to the human eye’s sensitivity (visual acuity) to represent the physical quantities of light radiation brightness. A specific value for isotropic luminous intensity is 1cd light […]
