First of all, let us look at what is an energy-saving lamp, also known as a power-saving light bulb, an electronic light bulb, a compact fluorescent lamp and an integrated fluorescent lamp, which refers to a lighting device that combines a fluorescent lamp and a ballast into a whole. In fact, energy-saving lamps are the energy-saving bulbs we have in our daily lives. Around 1970, energy-saving lamps were born in Philips in the Netherlands. At the time, this was a major breakthrough for Philips. The upper part of the energy-saving lamp is the lamp head, and the bottom is the lamp structure. The interface of this lamp is very similar to the interface of an incandescent lamp and can be mounted directly on the base of an incandescent lamp. In the store, we can easily find that the lamp of the energy-saving lamp has a spiral tube shape and a U-shaped tube shape.
Energy-saving lamps have the following disadvantages
1. The energy-saving lamp is the bright line spectrum, so the usual energy-saving lamp is purple-light, and it will be seriously discolored when viewed under the energy-saving lamp. Blue will turn purple, red and yellow will look more vivid. Therefore, energy-saving lamps should not be used in color matching work.
2. The ballast used in the energy-saving lamp generates certain electromagnetic radiation when it generates an instantaneous high voltage. The electromagnetic radiation of energy-saving lamps also comes from the ionization reaction between electrons and mercury gas. At the same time, energy-saving lamps need to add rare earth phosphors. Since the rare earth phosphors themselves are radioactive, energy-saving lamps can also generate ionizing radiation, which is harmful to humans compared with electromagnetic radiation. Uncertainty, excessive radiation of nuclear radiation is more detrimental to the human body.
3, energy-saving lamps have many advantages, small size, the structure of the lamp is very compact; the luminosity is relatively high, very energy-saving. Compared with incandescent lamps, its life is about 7 times higher. The downside of the energy-saving lamp is that it is slow to start up. When you turn it on, you can't see the light right away. Wait for a while. On the other hand, when you look at things under the energy-saving lamps, the color of things will change.
Second, what is the led light?
Led light is a kind of light emitting diode. Such a light-emitting diode is a semiconductor device capable of converting electrical energy into a solid state, which can directly convert electricity into light. It is worth noting that the Led lamp has a large projection range and no stroboscopic light, and does not harm the eyes. The power is also very strong, and the brightness of 15W is equivalent to the ordinary 40W fluorescent lamp, which is very power-saving and convenient. Led light strip
Advantages of LED lights LED energy-saving lamps save power, high brightness, long light, good light-emitting performance, wide voltage range, light source through the built-in controller of the microcomputer, can achieve seven color changes of LED, soft, colorful, colorful Low loss, led light with low energy consumption, green and environmental protection, suitable for families, shopping malls, banks, hospitals, hotels, restaurants, his various public places for a long time lighting. With incandescent tubes or low pressure fluorescent tubes, LED stability and long life are obvious advantages.
