Which eye protection is LED panel light and energy saving lamp?

Jul 25, 2019

In our life, we can't do without the use of lamps. Among all kinds of lamps, LED panels and energy-saving lamps are now the most widely used. Both lamps have their own advantages and disadvantages, LED panel lights and energy-saving lamps. Which eye protection?


First, the Light Emitting Diode, also known as a light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. The heart of the LED panel light is a semiconductor wafer with one end attached to a bracket, one end being the negative pole and the other end connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy. The semiconductor wafer consists of three parts, one part is a P-type semiconductor, in which the hole dominates, and the other end is an N-type semiconductor, where it is mainly electrons, and the middle is usually a quantum well of 1 to 5 cycles. When a current is applied to the wafer through the wire, electrons and holes are pushed into the vector sub-trap. In the quantum well, the electrons recombine with the holes, and then the energy is emitted in the form of photons. This is the LED panel light that emits 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 evolved from outdoor decoration and engineering lighting to home lighting.


In addition, energy-saving lamps, also known as compact fluorescent lamps (referred to as CFL lamps in foreign countries), have high luminous efficiency (5 times that of ordinary light bulbs), energy saving effect is obvious, long life (8 times that of ordinary light bulbs), small size, easy to use, etc. . It works in much the same way as fluorescent lamps. In addition to white (cold light), energy-saving lamps now have *** (warm light). Generally, under the same wattage, an energy-saving lamp is 80% more energy efficient than an incandescent lamp, with an average life expectancy of 8 times and a thermal radiation of only 20%. In a non-strict case, a 5 watt energy-saving lamp can be considered as an incandescent lamp equal to 25 watts, a 7-watt energy-saving lamp is about 40 watts, and a 9-watt is about 60 watts.


LED energy-saving lamps are small in size, light in weight, and encapsulated in epoxy resin. They can withstand high-strength mechanical shock and vibration, are not easily broken, and have a long decay period of brightness, so their service life can be as long as 50,000-100,000 hours, far exceeding 1,000 hours for traditional tungsten filament bulbs and 10,000 hours for fluorescent tubes. Since the LED luminaire has a service life of 5 to 10 years, it can not only greatly reduce the cost of luminaire replacement, but also has a very small current to drive the illuminating characteristics. In the case of the same lighting effect, the power consumption is only One-half of the fluorescent tubes, so LEDs also have the advantages of power saving and energy saving.


It can be seen that under the premise that the usage methods are correct, the LED panel light is relatively more eye-protecting.
