Energy Saving Lamp
Energy-saving lamps were first invented by Philips.
CFL is also called compact fluorescent lamp, which is regarded as a substitute for traditional incandescent lamp because of its energy saving and efficiency. China's energy-saving lamp promotion strategy has a long history, 2008 the state launched the "Green Lighting" project, urban and rural residents and enterprises using the winning enterprise energy-saving lamps, can enjoy a certain proportion of subsidies. That year, the national scope of the promotion of energy-saving lamps 62 million, to 2009, but also up to 120 million. Incomplete statistics, over the years, the national promotion of energy-saving lamps may be as high as 200 million.
The official name of the energy-saving lamp is the rare earth tri-phosphor compact fluorescent lamp, which was born in Philips, Netherlands, in the 1970s. Its background is mainly originated from the improvement of environmental awareness. Before lighting system only pay attention to quantity, in the past a long time people have gradually toward exquisite, pay attention to provincial energy effect.
Due to the wide use of lighting technology and lighting equipment, people's living standard is generally improved, the demand for lighting equipments is increasing rapidly, and the power consumption is enlarged, so the development of high efficiency and high-quality lighting equipment is started. With the increasing calls for energy-saving and emission reduction, environmental awareness has become increasingly popular.
Energy-saving lamps in recent years because of scrap caused by pollution, low efficiency is causing social concern. However, so far the domestic demand for energy-saving lamps is still very large.
If the energy-saving lamp is arbitrarily discarded, pollution is serious
According to the experts, 1 ordinary energy-saving lamps containing about 5 mg of mercury, only enough to be covered with a ballpoint pen tip, but infiltration underground can cause serious soil and water pollution. Because the boiling point of mercury is low, evaporation can be done at room temperature, the waste energy-saving lamp is broken, the instantaneous mercury concentration in the ambient air is exceeded. And once into the human body mercury exceeded, it will damage the central nervous system, and the human body inhaled 2.5 grams of mercury vapor can be lethal.
In this case, the recovery of China's energy-saving lamps is not optimistic. In the garbage classification rules before the introduction, in addition to IKEA and other very few stores, even in many sales of energy-saving lamps large furniture building materials chain supermarkets, there is no special recycling box. Ironically, many consumers do not know that the battery standard is revised, the old batteries are no longer mercury-free, and they do not need to be discarded to designated sites; After the garbage classification pilot, "hazardous waste" in the classification box, you can not find waste energy-saving lamps.
In fact, domestic lighting has three generations of change. These three kinds of lamps exist in the market at the same time, but they are the main commodities of the market at different times. The first generation of lamps refers to ordinary incandescent lamp, the second generation refers to fluorescent lamps, the third generation is still controversial, led, electrodeless lamp, CCFL lamp manufacturers are said to produce the third generation of lighting products.
Relevant policy provisions, from October 1, 2012 onwards, the total ban on the sale and import of more than 100 watts of incandescent lamps, after 4 years, in order to eliminate the different power of incandescent lamps, until 2016, more than 15 gigawatts of incandescent lamps completely out of the market. Before the incandescent lamp exits the market, the disadvantage of energy-saving lamps also gradually appear, so LED lights into the market is very fast, LED is leading the market's new trend.
The market has improved and the competition is still fierce.
LED is the abbreviation of light-emitting diode, called electronic energy-saving lamp, in essence it is a solid-state semiconductor device, can directly convert electricity into light, is a new light source. It is considered to be able to solve the problem of mercury pollution of energy-saving lamps, because mercury-free, and can save 80% of electricity, the service life of up to 8-10 years.
As early as the 60 's, General Electric company invented the LED. In the 70 's, Red LED was the first to be widely used in small calculators and electronic watches. Blue, red, green and other colors led in the next few decades to debut, used for indicators, lights, display, landscape lighting. But they couldn't work in everyone's living room until 1996, when the white LED was developed, LED technology began to change in the field of home lighting.
Industry insiders see, the development of a new generation of lighting technology war has begun, LED lights is the trend, the entire industry is vying for the commanding heights of LED technology. A survey of 700 building electrical contractors in the United States Electricalcontractor magazine shows that 33% of electrical contractors think LEDs are ready to replace incandescent bulbs, and 23% of contractors say LEDs will be ready to replace CFLs (CFLs) and 19% of those surveyed say LEDs will replace fluorescent lights.
In June this year, the Guangzhou International Lighting exhibition, the traditional lighting of the two giants Philips and Osram for the first time in years. "This is a very strong signal that the LED industry can replace the traditional lighting, which is a big shuffle process." "Some people in the industry say.
According to reports, this year several LED-related listed companies issued annual results table, from the performance table to see 31 companies, 25 companies recorded performance growth. Among them, such as Huaneng photoelectric net profit soared 1151.01%, in one swoop, Chau Ming Technology net profit of 60.8589 million yuan, year-on-year growth of 84.58%.
Compared with early technology immaturity, high price and low consumer acceptability, the LED market has improved significantly this year, but market competition is still fierce, and many of the businesses that have been the main business have failed. Industry insiders say the LED industry is still shuffling.
How to choose a light bulb
The amount of light a bulb can emit. or "brightness", "optical output." A standard 100-watt incandescent lamp produces about 1700 lumens.
Energy Efficiency (efficacy)
Lumens produced per watt. The higher the better, the higher energy utilization. China's standard is the highest level, the lowest level five.
A standard 100-watt incandescent lamp produces about 1700 lumens, and a 20-watt led produces the same lumen, which is equivalent to 100 watts.
The energy that is consumed to achieve nominal brightness.
LEDs that are below the initial brightness of 70% are considered unusable. Usually measured in hours or years, the latter is based on 3 hours per day.
The unit is Kelvin temperature. Usually, the color temperature of the soft white light is 3000K. The color temperature range of white light is from 4100K to 6000K, which is similar to the midday sun. The higher the color temperature, the more partial the Blues.
