In general home, in addition to air conditioning, refrigerator, the most power consumption is the lamp! To save energy and money, it's important to choose a more energy-efficient light bulb. Today, let's talk about the new energy-saving LED lights.
1. Understanding LED lights
Before we talk about how LED lights can save energy and money, we should first understand what led lights are?
LED lamp is made of semiconductor material. Because of its small luminous area and low output energy, LED lamp is not suitable for lighting in the past.
However, after continuous research and development and improvement, the luminous area of LED lamp is expanded, and its efficiency is higher than ordinary fluorescent lamp or fluorescent lamp, and can be used as lighting.
The advantage of using LED lamp is that it has no electric heating filament and does not need to discharge through gas. It is the most efficient light source at present. However, the disadvantage is that its price is relatively expensive, and the smaller the light source volume, the higher the light intensity (i.e. brightness) on the projected area, so the glare of LED lamp is also relatively strong.
2. More expensive but more durable
Compared with ordinary incandescent bulb or tube, LED lamp is more energy-saving and durable! According to calculation, LED lights can save up to 85% of electricity. However, its illumination is not inferior to ordinary electric lamps. For example, the brightness of 13 watt LED bulb is equal to that of 100 watt ordinary incandescent lamp, and its life span is 15 times longer than that of ordinary incandescent lamp, that is, about 15 years.
Compared with incandescent lamps, LED lamps are slightly more expensive, but in the long run, they can save more money because of their long life!
In order to encourage Chinese people to save energy, LED lights have replaced ordinary incandescent lamps. According to the website of the national environment administration, the price of LED lamps has been more economical and affordable than that in 2009 since 2012, and the general consumers can also afford it.
3. Benefits of using LED lights
The use of LED lights not only can save energy and money, but also has the following characteristics:
1. Lamp tube can replace fluorescent lamp, bulb can replace incandescent lamp, save electricity up to 85%, very environmental protection, do not need to replace frequently.
2. The service life is more than 15 years, which saves the cost of frequent lamp replacement and maintenance. Semiconductor chip light, no filament, no glass bubble, not afraid of vibration, not easy to break, service life up to 50000 hours (ordinary incandescent lamp service life is only 1000 hours, ordinary energy-saving lamp service life is only 8000 hours).
3. No mercury, lead and other harmful substances, no ultraviolet, infrared, etc. Green light source, soft light.
4. The heat energy produced by LED lamp is lower than that of lamp tube, which can reduce the indoor temperature.
5. There is no bad effect of stroboscopic, no noise interference.
6. High efficiency and energy saving: compared with the same brightness, 3W LED energy-saving lamp consumes 1 kilowatt hour power for 333 hours, ordinary 60W incandescent lamp consumes 1 kilowatt hour power for 17 hours, and ordinary 5W energy-saving lamp consumes 1 kilowatt hour power for 200 hours.
7. Health: light health, light contains less ultraviolet and infrared rays, less radiation (ordinary light contains ultraviolet and infrared rays).
8. Green environmental protection: it does not contain harmful elements such as mercury and xenon, which is conducive to recovery. Ordinary lamps contain mercury and lead and other elements.
9. Protection of vision: DC drive, no stroboscopic (ordinary lights are AC driven, it will inevitably produce stroboscopic).
4. Correct use of LED lamp
1. Always turn on and off the lamp carefully will reduce the life of the lamp. If you only leave for 5 minutes and come back, it is not necessary to turn off the lights, but if you leave for a period of time, you must turn off the lights at will, which will be more energy-saving and cost-effective.
2. The use of a modulator, especially for television, can reduce the brightness of the light, which can save power and reduce the glare from the TV screen.
3. Clean regularly, wipe off the dust on the bulb with a dry cloth, so that the bulb will not be covered by dust and the brightness is not enough, and must be adjusted to high brightness, a waste of power.
4. Don't think that the less the lights, the less the electricity. If you install electric lights in the space where you need them, you can light them at any time. On the contrary, you will save a lot of unnecessary electricity charges. For example, if the storage room needs a small lamp, it is not necessary to always turn on the lights of the whole larger space in order to illuminate a small space.
5. Purchase of LED energy saving lamp
1. LED brightness (MCD) is different, the price is different. The LED used for LED lamps shall meet the laser class I standard.
2. Antistatic ability. Led with strong antistatic ability has a long service life and high price. Generally, the LED with antistatic capacity greater than 700V can be used for LED lighting.
3. The same wavelength of LED, the color is the same, if the color is required to be consistent, then the price is high. It is difficult for manufacturers without led spectrophotometer to produce pure color products.
4. Leakage current LED is one-way conductive light emitting body, if there is reverse current, it is called leakage current. Led with large leakage current has short life and low price.
5. Led with different luminous angle has different luminous angle. especial. Luminous angle, high price. If full diffuse angle, the price is higher.
6. Life span is different. The key to quality is life, which is determined by light decay. Small light attenuation, long life; long life, high price.
7. The light emitting body of chip LED is a chip. Different chips have different prices. Chips in Japan and the United States are more expensive, while those in Taiwan and China are generally lower than those in Japan and the United States.
8. Chip size the size of the chip is indicated by the side length. The quality of LED with large chip is better than that of small chip. The price is directly proportional to the size of the wafer.
9. The colloid of ordinary LED is generally epoxy resin. The price of LED with anti ultraviolet and fire retardant is more expensive. High quality outdoor LED lighting should be UV resistant and fireproof. Each product has different design, and different design is suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
