Our ordinary lamps include incandescent lamps, fluorescent tubes and LED lamp beads. Can LED lamp beads really save electricity? Why do you have this question? It originated from an actual experience of intimate contact. Whether the lamp can save energy and reduce consumption, power consumption is an extremely important key factor in this. Needless to say about incandescent lamps, the relatively high temperature of LED bulbs during operation means that more electrical energy is converted into useless heat. With the same wattage and the same length of time fluorescent tubes and LED lamp beads, the actual touch is only that the temperature of the LED lamp beads is higher. Can it be said that the energy saving and consumption reduction of LED lamp beads is ultimately a "gimmick" promoted by the manufacturer?
The body temperature difference between fluorescent tube and LED lamp bead is mainly caused by the operating characteristics between the two. The difference in temperature is only one aspect, and it does not completely mean that the low temperature means more power saving. The energy saving lamp is a kind of lamps and lanterns products combined by fluorescent lamps and ballasts. When the fluorescent tube is operated, the ballast will heat the LED lamp beads of the lamp. The LED lamp beads emit electrons at the beginning, and the electrons interact with the methane gas in the lamp tube. , And finally complete the entire lighting process. According to the official data from Philips, fluorescent tubes can reach 64 lumens per watt, and LED lamp beads can reach 100 lumens per watt. The temperature difference between the two is related to the methane gas in the internal structure of the fluorescent tube, and the other is related to the volume between the two. The light-emitting element of the LED lamp bead is smaller, which will inevitably cause the accumulation of temperature. So, what are the characteristics of LED lamp beads?
The working principle of LED lamp beads is completely different from that of incandescent lamps and fluorescent tube lamps. LEDs are mainly used for lamps. One of the biggest features of LED lamp beads is energy saving and consumption reduction. Through the lamp brightness test, the incandescent lamp with the same brightness is 25W, while the LED lamp bead only needs 3W. Interested users can also calculate the amount of electricity saved every day; LED The lamp bead is a cold light source, the internal structure does not have the LED lamp bead structure, and the service life is up to ten times longer than that of traditional lighting products; the LED lamp bead uses the principle of red, green and basket to emit light, and it can also be adjusted to suit The different light source effects of human eyes not only help to protect our eyesight, but also do not contain harmful ultraviolet and infrared rays; LED lamp beads use diodes to emit light, and there is no need to fill the lamp tube with harmful gases such as mercury and xenon, which is more environmentally friendly.
Having said so many benefits, what are the disadvantages and deficiencies of LED lamp beads? Working in a continuous high temperature environment for a long time will cause the LED lamp bead to suffer from light loss. If the LED lamp bead is connected to the same aluminum substrate in series, one light bead will be damaged and all will not light up. The biggest disadvantage of LED lamp beads is the higher price, which is much higher than similar incandescent lamps and fluorescent tube products in the professional market. Although LED lamp beads are more energy-saving and environmentally friendly, just willing to make a difference by saving electricity, this will be a very long process, which may be the most fundamental reason why LED lamp beads have not been quickly popularized.
