If a room is to become bright at night, it cannot be separated from the illumination of the lamp, so that the development of the lamp is getting better and better. Not only the shape becomes more diversified, but also the function is increasing, for example, led lamp , it is different. In the past, the incandescent lamp, the perfect solution to the low-rise house can not install large-scale lighting defects, then what are the advantages and disadvantages of the led lamp ? The following together with the Xiaobian to learn more about it.
What are the advantages and disadvantages of led lamps?
First, the advantages of led lamp
1, environmentally friendly lamps
As we all know, traditional fluorescent lamps contain a lot of mercury gas. Once broken, these internal substances will be volatilized into the atmosphere, causing pollution, while LED lamps do not use mercury at all, and LED products do not contain harmful substances such as lead. The shell can also be recycled for use without damaging the environment.
2, less fever
Most of the lamps in the past use tungsten filaments to emit light, so they produce a lot of heat. The light efficiency of these products reaches 140 lm/W, and the light conversion rate is high. The surface temperature of the products is below 60°C, and no ultraviolet light is generated. Clothing will not fade.
3, protect the eyes
These products play a good role in the protection of the eyes. As we all know, ordinary lamps use alternating current, which produces approximately 100 to 120 strobes per second, while LED lamps use LED constant current. Work is the direct conversion of AC power to DC power, effectively reducing LED light failure, fast startup, no flicker, and eye protection.
Second, the disadvantages of led lamp
1, always, the heat problem is one of the most important problems of this type of product, while the impact of overheating on the LED is fatal, but with the development and maturity of LED technology, in the LED light efficiency increases, the heat problem will also Step by step solution.
2, compared to ordinary lamp, the price of such products is much higher, while the application is relatively small, mainly in urban lighting engineering and decoration projects, another power is also a major problem, the current LED lamps can only use low voltage Because of the direct current, it is necessary to have a power supply that converts AC power into DC power when it is used.
Led lamp purchase notes
1, in the selection, first of all to pay attention to packaging and trademark issues, in general, in accordance with national standards, the need to mark the following on the product packaging: rated voltage, voltage range, rated power, rated frequency, so when purchased, You can check whether the quality of the trademark printing is good and whether the logo is legible or not.
2, the appearance of the lamp is also a part can not be ignored, in the purchase, you can see if its appearance is cracked, loose and whether the interface was tampered, while the lamp's plastic shell is the kind of engineering plastic flame retardant, the surface Whether there is similar texture such as frosted glass.
Summary: Well, the above is about the advantages and disadvantages of the led light tube which is introduced, I hope to provide you with some help, I believe that in the future analysis of the advantages and disadvantages of the led lamp , the friends will be more handy, buy satisfaction The product.
