Which eye protection LED panel light and energy-saving lamp?
Our life is inseparable from the use of lamps. Among all kinds of lamps, LED panel lights and energy-saving lamps are currently used in the widest range. These two lamps have their own advantages and disadvantages. LED panel lights and energy-saving lamps Which eye protector?
First of all, LED panel light (Light Emitting Diode), also known as light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED panel light is a semiconductor chip, one end of the chip is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire chip is encapsulated by epoxy resin. The semiconductor wafer consists of three parts, one part is a P-type semiconductor, in which holes dominate, the other end is an N-type semiconductor, which is mainly electrons, and the middle is usually a quantum well of 1 to 5 periods. When the current acts on the chip through the wire, the electrons and holes will be pushed into the quantum well, and the electrons and holes will recombine in the quantum well, and then the energy will be emitted in the form of photons, which is the light of the LED panel light. principle. LED panel lights have many advantages such as small size, low power consumption, long life, non-toxic and environmental protection. LED panel lights have gradually developed from outdoor decoration, engineering lighting, to household lighting.
In addition, energy-saving lamps, also known as compact fluorescent lamps (abbreviated as CFL lamps abroad), have the advantages of high luminous efficiency (5 times that of ordinary bulbs), obvious energy-saving effect, long life (8 times that of ordinary bulbs), small size, and convenient use. . It works basically the same as a fluorescent lamp. In addition to white (cold light), energy-saving lamps are now available in *** (warm light). Generally speaking, under the same wattage, an energy-saving lamp is 80% more energy efficient than incandescent lamps, the average life span is 8 times longer, and the heat radiation is only 20%. Under non-strict conditions, a 5-watt energy-saving lamp can be regarded as equal to a 25-watt incandescent lamp, a 7-watt energy-saving lamp is approximately equal to 40 watts, and a 9-watt energy-saving lamp is approximately equal to 60 watts.
The bulbs of LED energy-saving lamps are small in size, light in weight, and encapsulated with epoxy resin, can withstand high-intensity mechanical shock and vibration, are not easy to break, and have a long brightness decay cycle, so their service life can be as long as 50,000-100,000 hours, far exceeding 1,000 hours for conventional tungsten bulbs and 10,000 hours for fluorescent tubes. Since the service life of LED lamps can reach 5 to 10 years, it can not only greatly reduce the cost of lamp replacement, but also because of the characteristics of very small current to drive light, under the same lighting effect, the power consumption is only 1/2 of the fluorescent tube, so LED also has the advantages of power saving and energy saving.
It can be seen that under the premise of correct use methods, LED panel lights are relatively more eye-friendly.
