Which energy-saving led lamp or energy-saving lamp?
Led lamps and energy-saving lamps are currently two common lamps in our lives. They are commonly used lighting lamps in our lives. Although there are still many people choosing these two lamps, they will also consider saving points. The problem is that there are many electrical appliances, and only energy-saving can make people more like it. Then which energy-saving led lamp or energy-saving lamp? I believe many people don’t know it. Let’s take a look at BENWEI LIGHTING.

Which energy-saving led lamp or energy-saving lamp?
First of all, it must be emphasized that LED bulbs save electricity than energy-saving lamps. This is what most people know, or have heard of, but many people still have doubts about this. After all, they have not calculated where this electricity is saved. .
Because of the different light-emitting principles of energy-saving lamps and LEDs, they have different luminous efficiency. 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 have different quality and different luminous efficiency, Philips energy-saving lighting efficiency is about 60lm/W). However, the luminous efficiency of LEDs is much higher than that of energy-saving lamps, and the current technical level has generally reached 90-100lm/W. So in essence, the brightness produced by 1W LED requires at least about 2W energy-saving lamps to achieve similar brightness. However, the actual brightness felt is also affected by many factors. The most direct factor is temperature. High temperature will produce Light decay, energy-saving lamps will produce bright heat when lit, and LED is a cold light source, the heat generated is much smaller than that of energy-saving lamps, so LED light decay is smaller than energy-saving lamps;
There are still many buyers. Users know that LEDs are more energy-efficient than energy-saving lamps, but they feel that the price of LEDs is more expensive than energy-saving lamps. The little electricity saved is not enough to make up for the extra money spent when buying lamps, so they decided to continue to buy relatively cheap Use of energy-saving lamps. The following table is the comparative analysis data of the use cost of LED and energy-saving lamps, taking T8 tube as an example.
Reminder: (LED life span is 2500 hours-30000 hours; energy-saving lamp life span is 5000 hours), the following is the comparison of purchase cost and electricity cost within 30,000 hours).
LED lights, light-emitting diodes are referred to as LEDs for short. Diodes made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc., can radiate 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. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED.
1. Energy saving, the energy consumption of white LED is only 1/10 of that of incandescent lamps and 1/4 of that of energy-saving lamps.
2. Longevity, lifespan can reach more than 100,000 hours, which can be described as "one-time-for-all" for ordinary household lighting
3. It can work at high speed. Energy-saving lamps will turn black and quickly break down if the filament is frequently turned on or off
LED disadvantages: high initial cost, poor color rendering, low efficiency of high-power LED, constant current drive (dedicated drive circuit required). In contrast, various traditional lighting has certain shortcomings.
Energy-saving lamps, also known as energy-saving bulbs, electronic 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 country launched the "green lighting" project, and urban and rural residents and enterprises enjoy a certain percentage of subsidies for using energy-saving lamps from winning bidders. The promotion of energy-saving lamps is of great significance, however, the environmental hazards of waste energy-saving lamps have also attracted attention. By the end of October 2012, hundreds of millions of energy-saving lamps had been scrapped in the energy-saving promotion project, each of which could pollute 180 tons of water and soil. The disposal and recycling of waste energy-saving lamps caused concern. Nevertheless, people's demand for energy-saving lamps is still growing, especially in the just approaching 2014, the demand is still increasing.
Energy-saving lamps
What are the advantages of energy-saving lamps:
1. Compact structure and small size.
2. High luminous efficiency 60Lm/w, power saving over 80%, saving energy.
3. It can directly replace incandescent bulbs.
4. Longer life span, 6-10 times that of incandescent lamps.
5. The inner wall of the lamp tube is coated with a protective film and the use of a triple spiral filament can greatly extend the service life.
What are the disadvantages of energy-saving lamps:
1. Mercury pollution occurs during the production process and after use and disposal. At present, Western countries attach great importance to mercury pollution. Chinese people are also increasingly aware of the harmfulness of mercury pollution
2. Because it is a glass product, it is easy to break, difficult to transport, and difficult to install
3. The power consumption is still too large
4. It is easy to damage, short life span, and save energy without saving money. This sentence is the best portrayal of it.
Energy-saving lamps are actually a kind of lamp that everyone is very familiar with. Energy-saving lamps are also called fluorescent lamps or fluorescent lamps. The light tubes we call are also a kind of energy-saving lamps. Energy-saving lamps mainly heat the lamp filament through the ballast, and the filament begins to emit electrons (because some electronic powder is coated on the filament). Under various actions, ultraviolet rays are generated to excite the phosphor to emit light. Due to the temperature ratio of the filament when the fluorescent lamp is working The working temperature of the traditional incandescent lamp is much lower, so its life span is also greatly improved. Under normal circumstances, it can reach more than 5000 hours. Because it does not have the current heating effect of the incandescent lamp, the energy conversion efficiency of the phosphor is also very high. The efficiency is high, the brightness is naturally high, and it is more power-saving. In theory, it can save more than 80% of the power than the traditional lamp, but it also has some very bad points.
The above is the introduction of which energy-saving led lamp and energy-saving lamp, I believe you will know more about it after reading it, and know which one you choose, the content is for your reference only, I hope it can be helpful to everyone .
