Deriving the cost of energy-saving light bulbs from the demand for electricity

LED bulbs are much more expensive than regular bulbs, but under certain conditions it can be turned into the world's cheapest lighting fixture. Instead of building new natural gas power plants or even photovoltaic power plants, utilities or third-party service organizations should respond to large-scale energy needs by giving LED bulbs to consumers.

“The utility of energy-saving light bulbs in the utility sector can save a lot of money. As long as the financing method is fully utilized, the energy saved by 2.5 cents per kilowatt is cheaper than the cost claimed by any power generation model – even if it is already depreciated and not included in the environmental tax. The coal-fired power plants are not as cheap as the former," said Alan & mid dot, co-founder of VantagePoint, a leading US venture capital firm; Sazman said.

Let's take a look at how to conclude that the cost of energy-saving bulbs is low. A high-quality LED bulb equivalent to 60 watts of illumination typically sells for more than $40, but most lighting fixture manufacturers—such as Philips, Osram, Toshiba, and BridgELux, Lemnis Lighting (Lemnis Lighting) Newcomers like this want to cut their unit costs by $20 to $25 in one to two years, down to $10. How to reduce LED prices is destined to become the number one topic at this year's Las Vegas International Lighting Fair.

An LED bulb equivalent to 60 watts of illumination consumes 7 to 12 watts of power. For the sake of argument, it is assumed that the average consumption is 10 watts. If the same jack is plugged into an incandescent bulb, each jack can save 50 watts of power. Calculated at $20 per bulb, the utility sector has to pay $200 million to buy 10 million LEDs. This has not included the factor of mass production discounts. In return, you can save 500,000 kilowatts of electricity. With just $400 million, utilities can reduce electricity demand by 1 million kilowatts, which is equivalent to the power generated by a multi-billion dollar nuclear or coal-fired power plant, which requires huge amounts of money and years of Time can be built.

The lighting industry is a "great industry worth hundreds of billions of dollars, and is emerging, and the development prospects are bright," Sazman commented. There is no shortage of sockets in the United States. According to data provided by Philips Lighting, the average household in the United States has 52 lampholders, and the number in Europe is 40. Then 100 million households have a total of 5.2 billion light bulb sockets, but most of them still use incandescent bulbs.

However, the lighting industry must first overcome some obstacles in order to grow and develop. First, the price of LEDs must be reduced and large-scale production will be formed. Manufacturers have made considerable progress in this area, but energy-saving light bulbs have little share in the commercial or residential lighting market. Last week, Philips said it would launch an LED light equivalent to 60 watts of illumination this year, but there is no offer. General Electric expects to launch an LED lamp equivalent to 40 watts of illumination at the end of this year and early next year, and the price is still high at 40 to 50 US dollars per trip. Second, consumers and the power supply sector must be satisfied with the color, stability, and quality of the LED bulbs. Many of the early-designed LED lights emit a kind of grotesque, light like an alien anatomy. Some consumers are concerned that LED lights can't support 35,000 to 50,000 hours as the ads claim. The compact fluorescent lamp claims to have a life of up to 15,000 hours, but it often burns out before it reaches this number (the life of an ordinary incandescent lamp is 1000 hours). Third, the power supply department must also find a way to ensure that users do not take the new light bulbs to eBay for sale. LED lights can only be used where smart meters are installed. However, unfortunately, some people have already been dissatisfied with the smart grid, claiming that the new meter will increase their electricity bills, and the smart grid will not only pose a safety hazard but also pose a great threat to personal privacy. Informing users that if they choose LED lights, they will spend more money on the power supply department is a huge public relations challenge. Fourth, the power supply department actually only uses more compact fluorescent lamps, which consume only 15 watts of power. Philips believes that most of these problems can be solved by providing light bulbs to consumers under the constraints of energy efficiency contracts by third-party service agencies. These companies can go directly into the home, improve imperfections, and charge for future power savings. With improved accurate data, power savings can also be tied to carbon credits.

Office building owners may be able to seize the opportunity to get LED fixtures for free. Fluorescent tubes must be used in US office buildings, so in this case, there may be no oil on the electricity bill. Even so, owners and real estate developers are happy to see the result of reduced maintenance costs due to reduced lighting. In the early days of LED testing, 1/2 of the cost reduction came from lower maintenance costs. According to the US Department of Energy's Building Data Book, 25% of the office building's energy consumption is spent on lighting.

But will the power supply department take action? "I think it will," Sazman said. "We have communicated with most public power supply agencies. The existing power supply capacity will be exhausted in the next 20 years, and the distribution of light bulbs is certainly better than using other Energy generation is cheaper."

Double concave Cylindrical Lens has two outward surfaces.

Cylindrical lenses are typically applied to focus incoming light to a line, or to change the aspect ratio of an image. they are used for the optics, lasers, medical science, electronics, tele-communication and others.
