What are the advantages of LED lamps compared to traditional lamps?
2019-05-06

In the past few decades, we have become accustomed to light bulbs, each with a life of about 1000 hours.


The energy crisis and the environmental movement in the 1970s stimulated the development of more energy-efficient technologies. But in recent years, consumers have only begun to touch these energy-saving technologies.


Fluorescent lamps (CFLs) first appeared in stores in the mid-1990s, replacing incandescent bulbs as more energy-efficient lights.


Although fluorescent lamps are very energy efficient, they have been unpopular because the fluorescent light is dim, it takes a while to light up after opening, and it contains mercury inside. If it is broken, it needs to be handled more carefully.


Most companies have eliminated fluorescent lights because of the better performance and cheaper LED lights.


LED lights have been around for a few years, but until recently prices have become very cheap and the quality of light has improved a lot.


Now LEDs can emit full-spectrum colors. For most people, the light from a good LED bulb is no different from incandescent.


How much can LED lights save?


LED bulbs are still much more expensive than incandescent bulbs. For example, a 100-watt incandescent bulb costs about $0.75 and consumes 0.1 degrees per hour. Each bulb has a life of about 1,000 hours. In contrast, a 23-watt fluorescent bulb produces similar mass of light, but costs about $3, consumes 0.23 watts per hour, and lasts 8,000 hours. To achieve the same level of illumination, a 14-watt LED bulb is required, costing $6, consumes 0.014 kWh per hour, and has a lifespan of around 25,000 hours.


It seems that although the LED bulb itself is more expensive, it has a longer life and consumes less power.


According to the above bulb calculation, according to the electricity cost of 1 yuan per kWh, during the use of an LED bulb, the user must pay a total of 350 yuan of electricity. In contrast, the cost of electricity for incandescent lamps at the same time is as high as $2,500. Saving 2,000 yuan sounds less appealing to consumers, but if you consider that a family may have two bedrooms, a living room, a kitchen and a bathroom, at least 5 lights, if all It is to use LED bulbs, then at least 10,000 yuan can be saved. This is not a small amount.


Moreover, LED lamps generate less heat than incandescent lamps, reducing the need for air conditioning in the hot summer months, and saving a lot of money for users.


Should we replace the LED bulb?


The answer to this question is already obvious. Although the price of LED bulbs is relatively high, the monthly electricity bill is enough to offset.


If you are using a fluorescent light now, you don't have to rush to replace it, and it will be more cost-effective to wait until the light bulb is dead.


LED bulbs not only help you save on living costs, but also contribute to the environment. The US Department of Energy estimates that LED lights will save approximately 41 billion kW/h in 2014, exceeding the output of one nuclear power plant. If all lighting is switched to LEDs, the savings will be more than 30 times. Studies have also shown that LED bulbs have a much smaller impact on the environment than incandescent and energy-saving lamps.


Because LED bulbs use less energy and generate less heat, LED bulbs are also safer. Incandescent bulbs generate enough heat to cause a fire under certain conditions, and LED bulbs cannot reach this temperature.
