The power factor is a measure of the efficiency of electrical equipment level of thecoefficient. Low power factor, equipment reactive power, thereby reducing the efficiencyof electricity use, an increase of the loss of the power lines, amounting to less than the energy requirement. 13W products such as lead ball lighting, led high bay, with a nominal power factor of 0.6, the standard requires the actual power factor shall not be more thannominal value low 0.05, that is not less than 0.55 measured only .520 to .527, outdoor led spotlights, but does not meet the standard requirements. The test, a sample power factor does not meet thestandard requirements, accounting for 2.5% of the total number of samples, namely:lead ball lighting 13W. According to experts, the power factor is not up to the main reason is the lamp electronic ballast component selection and circuit design caused by the irrational, outdoor led spotlights, there are some manufacturers to use inferior components to product performance can not achieve the design level.
The luminous efficiency is the ratio of the light emitted luminous flux and power consumption, while the luminous flux and reflects the light emitting intensity of lightperformance directly reflects the product is energy-saving. The project is not up to reflecta sample of low luminous efficiency or luminous intensity is not enough, outdoor led spotlights, up to lessenergy-saving, money-saving effect. The lead ball lighting 13W product standardsrequire that the initial light effect not less than 44 lm / W, but is actually only 36.65 lm / W~ 41.60 lm / W, does not meet the standard requirements.
Energy efficiency labeling that the product energy efficiency rating and performance indicators such as a logo. The level of energy efficiency labeling The lower the number,the more energy-saving. Virtual standard energy efficiency rating would misleadconsumers, but also unable to achieve energy saving. Star 5W products such as Trinityresidence, with a nominal energy efficiency rating of 2, in accordance with nationalstandards of its initial light effect not less than 46 lm / W, outdoor led spotlights, but is actually only 29.84 lm / W~ 34.49 lm / W, fell far short of the requirements even China’s energy-efficiency labelingof three requirements of the initial light effect not less than 36 lm / W.
