What Are Energy Saving Lights? Advantages And Disadvantages Of Energy-saving Lamps

What are energy saving lights

      Energy-saving lamp, also known as the energy-saving light bulb, electronic light bulb, compact fluorescent lamp and integrated fluorescent lamp, refers to the fluorescent lamp and ballast (ballast) combined into a whole lamp lighting equipment.

      Due to the wide use of lighting technology and lighting appliances, so that people's living standards generally improve, the demand for lighting equipment surges day by day, but also makes the expansion of power consumption, so began to pay attention to the development of high efficiency, high quality lighting equipment. The electron energy-saving lamp is mainly heated by the ballast to the lamp filament. At the temperature of 1160K, the filament starts to emit electrons (solid on the filament coated with some electron powder). The electron collides with argon atom in elastic collision. Emit 253.7nm ultraviolet light, ultraviolet light excitation phosphors glow, fluorescent lamp working filament temperature about 1160K, than incandescent lamp working temperature 2200K ~ 2700K low, so its life is also greatly improved to more than 8000 hours, and because it does not exist incandescent lamp as the current thermal effect, It can achieve 60 lumens per watt (lm).

      Energy-saving lamps are similar in size to incandescent lamps and have the same connector to the lamp holder, so they can be replaced directly. The official name for CFLS is rare earth tricolor compact fluorescent lamps, which were created by Philips in the Netherlands in the 1970s. It has been included in the 863 promotion plan by the state, and was first promoted in Jiaodong Peninsula, Shandong Province, among which Weihai Beiyang and Qixia Lighting Factory were the first two factories to respond, but due to the high cost in the early stage, it was difficult to promote. Guangdong relies on its advantageous geographical location, relying on the policy support of the state, mass production of energy-saving lamps with low-cost raw materials, and sold to the whole country. In the early days, people had a vague concept of energy-saving lamps, and the halogen powder energy-saving lamps produced in Guangdong had a lower cost and were sold to the market at a lower price. At present, 80% of China's energy-saving lamps are produced in Guangdong, and 80% of them are produced in Zhongshan Ancient Town.

      Under the premise of achieving the same light output, this kind of light source only needs to consume 1/5 to 1/4 of the electricity consumption of ordinary incandescent lamps, which can save a lot of lighting energy and costs, so it is called energy-saving lamp.

      The energy-saving lamp is actually a compact fluorescent lamp with a ballast. When the energy-saving lamp is lit, it first goes through the electronic ballast to heat the lamp filament, and the filament starts to emit electrons (because the filament is coated with some electron powder). The electrons collide with the argon atom inside the lamp tube, which then obtains energy and impairs the mercury atom inside. After absorbing energy, mercury atoms transition to ionize and form plasma state in the tube.

      The voltage at both ends of the tube directly through the plasma state conduction and emit 253.7nm ultraviolet light, ultraviolet light excited phosphors glow, because fluorescent lamp working filament temperature about 1160K, than incandescent lamp working temperature 2200K-2700K is much lower, so its life is also great progress, to more than 5000 hours, Because it uses a high efficiency of electronic ballast, while there is no current thermal effect like incandescent lamp, phosphors energy conversion efficiency is high, up to 50 lumens per watt or more, so energy saving.

Advantages and disadvantages of energy-saving lamps

The advantages of energy-saving light bulbs

      1. High light efficiency: the light efficiency of energy-saving lamps is generally 5-6 times that of ordinary incandescent lamps in the case of the same electricity consumption, and the light efficiency is very high.

      2. Long life: the life of the energy-saving lamp is generally up to 5000 hours, is 5 times that of the ordinary incandescent lamp

      3. Small size: the volume of energy-saving lamps is generally very small, and the appearance is more beautiful, not only does not occupy space, but also has the role of decoration.

      4. Good for eye health: energy-saving lamps do not have the flickering sense of incandescent lamps, so there will be no eye fatigue in the face of a long time, can be a good protection of eyes.

      5. Good color rendering: the color rendering index of energy-saving lamp is about 80RA, 2 times that of ordinary incandescent lamp.

The disadvantages of energy-saving lamps

      1. Energy saving lamp starts slowly

      2. The price is relatively high and the energy-saving lamp tube is accidentally broken. Mercury volatility is very harmful to the human body

      3. energy-saving lamp is bright line spectrum (discontinuous), so the usual energy-saving lamp partial purple light, in the energy-saving lamp to see things will be seriously discolored. Blue will turn purple and red and yellow will look brighter. Therefore, it is not appropriate to use energy saving lamps in the workplace of color matching.

      As we all know, the invention of energy-saving lamp makes people further leave the darkness, ushered in the light, because it compared to incandescent lamp cheap and good production, higher brightness, so it has been a large number of applications, there is a trend to gradually replace incandescent lamp......

      But CFLS contain harmful substances such as mercury, which is too polluting to the environment. So people are looking for ways to use new light sources instead of CFLS. LED light arises at the historic moment, because it is relatively cheap and easy to produce, so it has been used in a large number of applications, there is a trend to gradually replace energy-saving lamps.

      Read the above introduction about the advantages and disadvantages of energy-saving lamps, you are not to have more understanding of energy-saving lamps, want to know more about the knowledge of lamps, please continue to pay attention to Jiuzheng lamp network.
