Guide: With the improvement of living standards, people's household electricity consumption has also begun to pay attention to the principle of low energy environmental protection and economy, so that not only can save electricity expenses for household electricity, low-energy environmental protection appliances will make the environment more healthy and low pollution. Today, I want to talk about led lights and energy-saving lamps. Although both are lighting types, there are still differences. What is the difference between energy-saving lamps and led lamps? In fact, it is necessary to understand how to choose suitable lamps and then understand The advantages and disadvantages of energy-saving lamps, I believe that the difference between energy-saving lamps and led lights can be quickly found out.
Energy saving lamp
What is the difference between energy-saving lamps and led lamps?
What is the difference between energy-saving lamps and led lamps? LED lamps are divided according to the principle of illumination. There are two types of tungsten filament white lamps and fluorescent lamps (fluorescent lamps). Energy-saving lamps are divided according to energy consumption ratio. Non-energy-saving lamps are distinguished.
What is the difference between energy-saving lamps and led lamps, of course, if it is led energy-saving lamps and ordinary "energy-saving lamps" (mostly fluorescent lamps). The led lamp is an electro-optic light mode, the tungsten white light is an electro-thermal-light mode, and the fluorescent lamp is an electro-thermal-electric-light mode. It can be seen that the conversion efficiency of the led lamp is relatively much higher. In addition, the led light belongs to the cold light, and the tungsten white white light and the fluorescent light belong to the hot light. Which specific energy saving can not only look at the luminous efficiency and the efficiency of the luminaire, but at present, the energy consumption ratio of led is relatively low, and the wattage required to achieve the same brightness is also lower.
What is the difference between energy-saving lamps and led lamps? LED lamps are cold light sources, and energy-saving lamps are energy-saving due to special fluorescent materials. The same voltage and power, led is the most energy-efficient, then energy-saving lamps, and finally the ordinary light bulb, the brightness is also the same.
How to choose the right luminaire
How to choose the right luminaire, the advantages and disadvantages of the four common lamp luminaires:
1, incandescent lamp
Advantages: small light source, a wide variety of lampshade forms; large versatility, multi-color variety, directional, scattering, diffuse and other forms; can be used to enhance the stereoscopic effect of objects, incandescent light is closest to sunlight color.
Disadvantages: Non-environmental protection is a big disadvantage. When using incandescent lamps, 95% of the electrical energy is consumed in heating. Only 5% of the electrical energy is truly converted into visible light; the heating temperature is high and the heat evaporates quickly. Short life (1000 hours), high infrared content, easy to be affected by vibration, low color temperature, yellow.
LED bulb
2, energy saving lamp
Advantages: high luminous efficiency, more than 5 times that of ordinary incandescent lamps, energy saving effect is obvious; long life, about 8 times that of ordinary light bulbs; and small size, easy to use.
Disadvantages: light decay, low color rendering, incandescent and halogen lamps with a color rendering of 100, complete performance; energy-saving lamps are mostly between 80 and 90, low-color light source not only looks at the color is not beautiful It is also harmful to health and vision.
3, fluorescent lights
Advantages: Energy saving, about 60% of the energy consumed by fluorescent lamps can be converted into ultraviolet light, and other energy is converted into thermal energy. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of the daylight lamp is about 60% x 40% = 24% - about twice that of a tungsten lamp of the same power.
Disadvantages: light decay occurs, fluorescent lamps are less colored than incandescent lamps; flashing lights have a certain impact on vision; in addition, mercury contamination occurs during production and after disposal.
4, LED lights
Advantages: LED lamps have many advantages such as small size, low power consumption, long life, non-toxic and environmental protection, etc., originally applied to outdoor decoration, engineering lighting, and now gradually develop into household lighting.
Disadvantages: expensive, need constant current drive, heat dissipation is not easy to light decay.
Stud Triac is developed on the basis of common thyristors. It can not only replace two thyristors with reverse polarity in parallel, but also requires only one trigger circuit and is an ideal AC switch device. . Its English name TRIAC is the meaning of the triac.
China leading manufacturers and suppliers of Stud Triac,Ir Stud Triac, and we are specialize in Stud Type Triac,Sc108 Data Triac Stud, etc.
