At present, LED lighting is an energy-saving and environment-friendly lighting solution, especially people's awareness of environmental protection and the establishment of relevant laws have made people pay more and more attention. It is understood that LED tube will become the light king of the trend of lamps. With the advancement of technology, the availability of LED tubes is high. More and more people choose LED lamps, and the era of LED lighting has arrived.
The impressive energy saving and environmental protection is the highlight of LED tubes, which makes traditional incandescent lamps and fluorescent lamps. Less power consumption of LED tubes results in more comfortable and energy-efficient illumination, and LED lamps are brighter than incandescent and fluorescent lamps at the same power .
Some people may discuss the price of LED tubes is expensive, the initial investment cost is slightly expensive, but the use of LED lamps can save a lot of electricity costs, LED lighting is particularly suitable for some commercial lighting time, such as in supermarkets, if you want to store supermarket lighting energy saving, using LED T8 lamp is the best choice; than conventional fluorescent tubes 60% energy saving.
The advantages of choosing LED T8 lamps:
1 . Ultra-efficient and energy-saving LED tubes save more than 50% of electricity consumption compared to traditional lamps . Specifically, LED lamps are 90% more energy efficient than incandescent lamps at the same brightness, and fluorescent lamps are 50% , which means energy saving, and it is important to save you more electricity.
2 . Durable and reliable LED tube life is more than 50,000 hours. The normal service life can reach 5-6 years.
3 . Compared with the fluorescent tube, the life of the fluorescent tube is only 8,000 hours, and the replacement and maintenance cost is high every year. The life of the LED tube is more than 5 times, and the cost of repairing and replacing the bulb is almost unnecessary.
　　 LED T5 lamps are available in a full range of colors. They are available in three conventional colors: warm white (2700K-3500K) , natural white (3500K-5500K) , and cool white (6000K-8000K) .
Warm white LED tubes can emit a yellow glow , similar to the color of an incandescent bulb.
If you like natural white or daylight fluorescent lights, choose natural white.
- The Description of TV Antenna
-
In the cable TV system, the task of the antenna is to receive the open channel TV signal or satellite TV signal in the air, and send it to the system for processing, transmission and distribution. Among them, the antennas receiving VHF and UHF open-circuit TV signals are called TV receiving antennas.
- TV receiving antenna is an important part of wireless TV signal receiving, and it is the gate for radio waves to enter the CATV system. There are two kinds of antenna: passive antenna and active antenna. The active antenna can make the antenna system realize high gain and high signal-to-noise ratio receiving.
