Which is more energy-efficient, led lamps or energy-saving lamps

Led lamps and energy-saving lamps are two common types of lamps in our lives. They are commonly used lighting fixtures in our lives. Although there are still many people who choose these two lamps, they will also consider saving some points. The problem, there are many electrical appliances, only energy saving will make people like them more. So which is more power efficient, LED lights or CFLs? First of all, it must be emphasized that LED bulbs save energy than CFLs, which is the most common reason for most people. I know, or have heard of it, but there are still a lot of people who are skeptical. After all, they haven't figured out where to save electricity. Due to the different light-emitting principles of energy-saving lamps and LEDs, their luminous efficiency is also different. The luminous efficiency of halogen powder energy-saving lamps is only 30-40lm/W, and the luminous efficiency of three-color energy-saving lamps is higher than that of halogen powder energy-saving lamps. About 40-60lm/W (different brands of products, different quality, different light effects, Philips energy-saving lamps about 60lm/W). However, the luminous efficiency of LED is much higher than that of energy-saving lamps, and the current technical level generally reaches 90-100lm/W. Therefore, in essence, the brightness produced by 1W LED requires at least about 2W energy-saving lamps to achieve similar brightness. However, the actual brightness is affected by many factors. The most immediate factor is temperature. Light decay, energy-saving lamps will produce bright heat, and LED is a cold light source, the heat generated is much smaller than energy-saving lamps, so the light decay of LED is smaller than energy-saving lamps; there are many buyers, users know that LED is more energy-efficient than energy-saving lamps , the lamp is more energy-efficient, but I feel that the price of LED is more expensive than that of energy-saving lamps. The following table is the comparative analysis data of the use cost of LED and energy-saving lamps, taking T8 lamp as an example. Reminder: (LED lifespan is 2500 hours-30000 hours; energy-saving lamps lifespan is 5000 hours). LED lights, light-emitting diodes are collectively referred to as LEDs. Diodes made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc., can emit visible light when electrons and holes recombine, so they can be used to make light-emitting diodes. Used as indicator lights in circuits and instruments, or composed of text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. According to chemical properties, it can be divided into organic light emitting diode OLED and inorganic light emitting diode LED. 1. Energy saving, the energy consumption of white LEDs is only 1/10 of incandescent lamps and 1/4 of energy-saving lamps. 2. Long life, more than 100,000 hours, it can be described as 'once and for all' for ordinary household lighting 3. It can work at high speed. If CFLs are turned on and off frequently, the filaments will turn black and break quickly. Disadvantages of LED: high initial cost, poor color rendering, low efficiency of high-power LED, constant current drive (requires a special drive circuit). In contrast, all kinds of traditional lighting have certain drawbacks. Energy-saving lamps, also known as energy-saving light bulbs, electronic light bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts (ballasts) into a whole. In 2008, the state launched the 'green lighting' project, and urban and rural residents and enterprises used the energy-saving lamps of the winning enterprises to enjoy a certain percentage of subsidies. The promotion of energy-saving lamps is of great significance, but the environmental hazards of waste energy-saving lamps have also attracted people's attention. As of the end of October 2012, hundreds of millions of energy-saving lamps have been scrapped from energy-saving promotion projects, each of which can pollute 180 tons of soil and water. The treatment and recycling of waste energy-saving lamps has attracted much attention. Despite this, the demand for energy-saving lamps is still growing, especially in 2014, which has just arrived, and the demand is still growing. What are the advantages of energy-saving lamps: 1. Compact structure and small size. 2. High light efficiency of 60Lm/w, saving more than 80% of electricity, energy saving and environmental protection. 3. The incandescent bulb can be replaced directly. 4. Longer life, 6 to 10 times longer than incandescent lamps. 5. The inner wall of the lamp is coated with a protective film, and the triple spiral filament is used, which greatly prolongs the service life. What are the disadvantages of energy-saving lamps: 1. There is mercury pollution in the production process and after being scrapped after use. At present, western countries attach great importance to the problem of mercury pollution. People are more and more aware of the danger of mercury pollution 2. Because it is a glass product, it is easy to break, difficult to transport, and difficult to install 3. Its power consumption is still too large This sentence is its best portrayal. Energy-saving lamps are actually a kind of lamps that everyone is very familiar with. Energy-saving lamps are also known as fluorescent lamps or fluorescent lamps. The light tube we are talking about is also a kind of energy-saving lamp. The energy-saving lamp mainly heats the filament of the lamp tube through the ballast, and the filament starts to emit electrons (because the filament is coated with some electronic powder), which generates ultraviolet rays to excite the phosphor to emit light under various actions. The operating temperature of traditional incandescent lamps is much lower, so their lifespan is also greatly improved, which can reach more than 5000 hours under normal conditions. Because it does not have the heating effect of electric current like incandescent lamps, the energy conversion efficiency of phosphors is also very high. High efficiency, naturally high brightness, and more power saving. In theory, it saves more than 80% of electricity than traditional lamps, but there are also some very bad places.
