Should hotel engineering lights use LED light sources? What are the advantages and disadvantages of using LED light sources?

LED light sources, such light-emitting devices, can be made very small, only a few millimeters, and installed on the wall or ceiling. If the lights are not turned on, their existence is almost unnoticeable, thus eliminating the need for Ordinary incandescent lamps need to be equipped with lampshades to prevent light from dazzling the eyes. In addition, this kind of light bulb has a long life and almost does not need to be replaced after installation. In addition to being durable, this kind of light bulb also has great potential in energy saving.

1. High luminous efficiency. The light efficiency of LED will reach 50-200 lumens/watt after improvement. Moreover, its light has good monochromaticity and narrow spectrum, and can directly emit colored visible light without filtering.

2. Low power consumption. The LED single tube power is 0.03~0.06 watts. It adopts DC drive. The single tube driving voltage is 1.5~3.5 volts and the current is 15~18 mA. It has fast response speed and can be used at high frequencies. operate. Under the same lighting effect, the power consumption is one ten thousandth of that of incandescent bulbs and one half of that of fluorescent tubes

3. Long service life. The LED lights are small in size, light in weight, and encapsulated in epoxy resin, which can withstand high-strength mechanical impact and vibration and is not easily broken. The average life span is 100,000 hours. The service life of LED lamps can reach 5 to 10 years, which can greatly reduce the maintenance costs of lamps and avoid the pain of frequent lamp replacement.

4. Strong safety and reliability, low calorific value, no thermal radiation, cold light source, safe to touch: can accurately control the light pattern and angle of light, soft light color, no glare; does not contain mercury, Sodium and other substances that may be harmful to health. The built-in microprocessing system can control the luminous intensity and adjust the luminous mode to achieve the combination of light and art.

However, LEDs also have shortcomings compared with other light sources, such as low color rendering in white light lighting. The color rendering index of white LEDs currently produced using yellow phosphors and blue light is about 80. It is okay as general lighting, but it is insufficient for some places with high color resolution requirements. Although the color rendering index can be increased to 90 or higher by adding appropriate red phosphors and other methods, there is still a certain gap compared with 99 of incandescent lamps, and its efficiency will be affected. Color rendering can also be improved through RGB color mixing processing, but more work needs to be done to popularize and apply the technology. Therefore, LED still needs to be improved in terms of color rendering. As for the high price and large one-time investment, in fact, considering the overall cost, using LED in many situations still saves a lot of costs.
