LED lighting bulbs walk into the home more efficient and longer life

LED lights are more efficient and have a longer life than other types of lights and bulbs. According to usage, its service life can be up to 20-30 years. Unlike compact energy-saving lamps, led light is stable and does not flicker. The increase in the number of off and on lights will not reduce the service life.

The inadequacy of LED lights is light blue, light colors, people feel cold, especially when compared with incandescent lamps. Other flaws include direct light, which is suitable for use as a spotlight, but not for desk lamps. And LED is expensive and not easy to buy in ordinary stores.

But all of the above will be fundamentally changed. In the United States federal government to promote the lighting efficiency of the initiative, consumer lighting company began to produce LED light bulbs, installed with a familiar base to diffuse reflection. The current LED bulb output is still relatively low, but the quality is quite good.

Lighting Science Group of Florida provided EcoSmart LED light bulbs to Home Depot, an American chain store. Even if the bulb inventor Thomas Edison reincarnated, I am afraid I do not know EcoSmart bulbs: EcoSmart bulbs are wing-shaped cones, fins are radiators, the top is flat, and the light sources are scattered.

In the past year, lighting manufacturers have introduced LED bulbs that are similar to conventional bulbs. Although they cannot emit light from all directions as in the current state of the art LED bulbs, they can disperse the light source very well. Use this LED bulb.

The key is that the price of LED bulbs has dropped, and the price of LED bulbs equivalent to 40 watts produced by the Lighting Science Group is below $20. At the end of this month, it will be able to purchase online or through the Home Depot chain, as well as purchase LED bulbs from other companies.

Brightness, energy consumption and money contrast:

Comparisons made by installing the EcoSmart A19 concluded that the LED bulbs are white and do not emit yellow light like the compact energy-saving lamps. The EcoSmart A19 has a rated power of 8.6 watts, an actual power consumption of 6 watts, and a brightness equivalent to that of a 40-watt ordinary light bulb. The actual power consumption of a compact energy-saving lamp at the same power rating is 9-13 watts. However, the A19 output brightness is 429 lumens and the brightness is not enough.

Zachary Gibler, chief executive of the Lighting Science Group, said that in the first quarter of next year, the company will introduce LED bulbs with a brightness equivalent to a 60-watt ordinary light bulb, which will have a brightness of 800 lumens and a practical power consumption of only 9 watts. Other lighting companies are also actively promoting LED bulbs. Sylvania, Philip, General Electric, Lemnis Lighting and others plan to introduce LED bulbs with a brightness of 60 watts.

The price of LED bulbs has not yet been determined, but Gilble said that LED bulbs with a brightness equivalent to a 60-watt ordinary bulb are priced at about $35. Over time, the power savings are quite objective, but for an illumination For light bulbs, this price is still too high. Ghibler said: "We will eventually make the new technology and lighting output and quality match, replacing the current halogen bulbs and incandescent bulbs with LED bulbs that users can afford, highlighting the attractiveness of LED bulbs."

LED light bulbs have their own unique advantages in certain situations, such as lighting and where light bulbs are not easily replaced. Even with high LED prices, installing long-life LED bulbs at the above locations is of great significance to most people. As manufacturers continue to improve their technology, the price of LED light bulbs will eventually drop. Like chips, tablets, and other high-tech products, prices will gradually decline in time.

Gilble expects that the price of an LED bulb equivalent to a 60 watt ordinary bulb will fall to less than $10 in two years. The preferential policies provided by the public utilities department will make their prices fall more and make LED bulbs more popular. In the future, it is not just the lumens per watt but the lumens per watt per dollar.

Cognitive lumens

Consumers should pay attention to the praise of LED bulbs. On Wednesday, the US Federal Trade Commission (FTC) sued the LED manufacturer, American Lighting, claiming that the company exaggerated its LED bulb output and life expectancy. The U.S. Department of Energy will develop a detailed plan later this year that will involve multiple retailers and certification companies to help users learn about new lighting technologies.

James Brodrick, head of the lighting department at the Department of Energy, said: “We want consumers to use new high-tech terms when buying lighting products. LED bulbs are no longer rated by the rated power watts, and It is expressed in lumens per watt, which shows the color temperature and the efficiency.In general, if the brightness is less than 800 lumens, it cannot be called the brightness equivalent to a 60-watt ordinary light bulb.
