Currently on the market, energy-saving lamps and led high-pole lamps are relatively hot, both of which have energy-saving and environmental protection functions. Energy-saving lamps, also known as power-saving light bulbs, electronic light bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to a combination of fluorescent lamps and ballasts as a whole lighting equipment. LED light, light-emitting diode is referred to as LED for short. It is a new type of lamp. What is the difference between the two?
Energy-saving lamps are short for CFL (Compact Fluorescent Lamp), which is mainly energy-saving compared with the original incandescent bulb. LED light bulbs refer to light bulbs that use LEDs as a light source. They also have high luminous efficacy. They are currently new light bulbs, and they have the tendency to replace CFLs. In recent years, some LED lights have also been basically displayed.
At present, the light efficiency of the two is slightly lower than the CFL, and the CFL generally has a light efficiency of 50-65lm / W. The light efficiency of LED itself is very high, most of which are between 100-130lm / W at present, but due to problems such as the light emitting angle of LED, the light efficiency of the whole lamp is about 65-80lm / W, the difference between the two is not too large However, the price of CFL and LED with the same luminous flux is generally about 2-4 times, the power is small, the price is small, the power is large, and the difference is large. The life between the two is slightly higher than that of LEDs compared to energy-saving lamps. The nominal life is 6000-12000h, and the nominal life of LED is 10000-20000h. These comparisons are only for comparison of some exports to the EU or North America. Due to the uneven quality of domestic sales, detailed assessments cannot be made. However, the life expectancy is generally the best in order to sell in these regions.
For vision damage, incandescent light bulbs are better than CFLs, and CFLs are better than LEDs. In particular, most of the LED domestic lamps currently sold domestically do not pay attention to the impact of LEDs on vision, and deliberately reduce the light efficiency loss between the LED light source and the entire lamp, so that the entire lamp has a higher light efficiency. Data such as luminous flux, using a single-stage PFC circuit (high ripple, easy to fatigue eyes), to meet China's first-class standards for lamps, low-end price requirements
