Particularly, when the working current of the LED chip is less than 20% of the rated current, the luminous efficiency of the light source can be effectively improved. Under the prior art, the light efficiency can reach more than 230 LM/W. High light efficiency means high electro-optic conversion efficiency, and the effective utilization of electric energy is improved. Therefore, the chip is prevented from working under the condition of large current, and the light attenuation resistance and the thermal stability of the LED are improved. The light source has high luminous efficiency, high luminous intensity of the lamp beads, high power density and strong light intensity output, can effectively improve the energy utilization rate and achieve the effects of energy conservation and emission reduction.
