A new solution for school led tube lighting
1. The birth of new products: School classrooms, libraries, teaching buildings and other occasions generally require large-area lighting, and LED tubes are widely used. Ordinary LED tubes are usually used. Directly using the switch to control its lighting is of great help to energy saving. In order to further improve the energy-saving effect, Langte invented the intelligent light-sensing led lamp tube, which saves 30% of the electric energy than the ordinary led lamp tube. So what is going on?
2. Principle: What is a light-sensing led tube? It is to use light to sense the sensor head of the led tube to realize the control of the led tube. When the light is too bright during the day, the LED tube automatically reduces the brightness in order to save energy, and when the light is too dark at night, the LED tube automatically fills up the light. And it works intelligently, without manual control.
3. Is there a case for common problems? Yes, the general classroom is very bright near the window, and the light-sensing LED fluorescent lamp will automatically reduce to about 3-5w, and a small amount of light will be added. The middle of the classroom is relatively dark. At this time, the light-sensing led tube automatically rises to 9-10w, and the supplementary light is further increased. At night, the LED tube achieves full power operation and its brightness reaches its maximum.
What are the benefits of this? First, while meeting the brightness during the day, the LED tube saves a lot of energy, and the tube does not need full power lighting. Second, use full power at night, which also meets the illumination requirements.
4. Energy-saving effect: If a classroom uses 8 tube lights, 40w*8=320w, and it is used for 10 hours a day, the total power consumption is 320w*10=3200w, which means that it consumes 3 kWh per day.
If the light-sensing led fluorescent lamp is used, the electricity consumption during the day is 5w*8=40w, 3 hours at night, 3*16w=48w, a total of 88w per day, that is, the daily power consumption is 0.088 kWh.
Electricity saving: 3-0.088=2.912 kWh, energy saving 90%
