First, solar energy: low conversion rate, LED lamp: high luminous efficiency

Solar energy is most criticized for poor conversion and low charging efficiency. However, the high luminous efficiency of LED lamps makes up for the low conversion rate of solar energy.

The luminescence efficiency of traditional incandescent lamps is 8-15lm/W, and that of solar LED lamps is 70-120lm/ W, which is about eight times higher than that of traditional incandescent lamps. That means a 20-watt dot solar LED light is about as bright as a 160-watt incandescent bulb.

Solar energy: unstable supply; LED lights: Enough

Second, in addition to the low conversion rate, solar energy also has a strong instability. The alternation of day and night, the interval between rain and sunshine, will affect the sun's irradiation time, resulting in a limited solar charging time, which means that the solar lamp can consume a limited amount of electricity per unit time.

LED lamp energy-saving characteristics, can ensure that the use of LED lamp solar lamp in the limited charging time, to achieve a longer lighting time.

The lighting time of solar LED lamp generally reaches 8-12 hours. At the same time, the built-in automatic adjustment system of solar LED lamp enables the solar lamp to illuminate normally in cloudy and rainy weather, which basically solves the disadvantages brought by the instability of solar energy.

Three, solar energy: waste will cause pollution; LED lamp: long life

However, with the development of solar energy technology, the life of solar panels has been continuously improved, and even reached 20 to 30 years. The life of lithium iron phosphate batteries used by little solar LED lamps has reached 8-10 years. The only factor limiting the life of a solar lamp is the bulb itself.

Traditional incandescent bulbs have a life span of about 1,000 hours, while CFLS have a life span of about 6,000 hours, while leds have a life span of about 50,000 to 100,000 hours (the term here refers to how long they stay on). With solar lights on for eight hours a night, traditional incandescent bulbs will last 125 days, CFLS 750 days and leds 6,250 to 12,500 days.

The use of LED lights can prolong the life of solar lamps, greatly reducing the environmental pollution caused by the waste of solar lamps.

As LED lamp effectively solves the problems existing in the application of solar energy and makes up for the defects caused by the characteristics of solar energy, so after the relative maturity of LED lamp technology, the solar lamp industry has developed by leaps and bounds. With the continuous development of solar energy and lighting technology, solar energy and LED lamp will be more and more tacit understanding, become the vanguard of energy conservation and environmental protection.
