How to choice LED lights

How to choice LED lights? How to choice LED lights? LED will certainly become the fourth generation of lighting, its development momentum is growing, the main advantages are: energy-saving and environmental protection, long life, no stroboscopic harm to the eyes, do not attract mosquitoes. As long as the heat dissipation design of high-power LED lamps is good enough, the life of 30-50,000 hours is not a problem. The definition of life is: because the LED is a semiconductor component, its wafer will be affected by temperature to produce light decay, when the luminous flux of the LED is less than 30% of the initial luminous flux due to light decay, basically secondary LED lamps have no illumination significance. That is to say, life summary, although the LED lamp can still be lit at this time, the brightness has been seriously reduced, so the heat dissipation of LED lamps is very important. You said that the object illuminated by the LED lamp will be discolored because of the lack of a c […]

LED lamp selection techniques

LED lamp selection techniques 1. Packaging and trade marks LED lamp selection techniques. The state compulsorily requires the manufacturers of LED lamps to mark the following contents on the product packaging: rated voltage, voltage range, rated power and rated frequency. Generally speaking, the trademark printing quality of high-quality products is good, the logo is clear and distinguishable, it is not easy to wipe off with soft and wet cloth, and there are manufacturers trademarks and related certification marks, while poor-quality LED lamps and lanterns can be seen from their trademarks and labels at a glance. Generally, poor-quality LED lamps and lanterns are used simply by their manufacturers in order to save costs. Easy to print or duplicate labels, with a touch of the hand will be able to remove its ink, and there are no national provisions on the above, so when encountering this type of lamps and lanterns, try not to buy. 2. Appearance of LED tube LED lamp selection techniques. […]

LED bulb lamp

LED bulb lamp   LED bulb lamp is the appearance of people have been accustomed to the shape of the bulb – spherical, internal light source selection is LED chip. With all the advantages of LED lamps: 1, energy-saving, environmental protection; 2, long service life; 3, no stroboscopic, green.   More energy saving: the energy consumption of LED lamps is 1/4 of energy saving lamps, and 1/10 of incandescent lamps.   Long life: the life of LED lamp is up to 50 thousand hours, and life expectancy is 5-10 times of that of the energy-saving lamp.   More healthy: uniform light guide, no stroboscopic, no glare, no ultraviolet and infrared.   More environmentally friendly: no harmful substances such as mercury, recyclable, protect the green earth.   Full-color change: rich colors, showing vivid and delicate patterns and effects.   Installation convenience: installation is simple, can directly replace the incandescent lamp, maintenance cost is very low. &nb […]

What happens to LED bulbs at high temperatures for a long time?

What happens to LED bulbs at high temperatures for a long time? Will LED bulbs be as hot as incandescent bulbs? Many consumers think that LED bulbs are cold light sources will not be as hot as incandescent bulbs, in fact, this is wrong. LED bulbs will still generate heat, the reason for the LED bulbs added to the electric energy has not been completely converted to light, part of the conversion of heat, basically After the electricity is switched on, only the electrical energy of 20%-30% is converted into light, and the other 70% is converted into heat energy. LED bulbs lamp If the heat dissipation of the LED bulbs is not good, it will make the junction temperature of the LED chip rise rapidly. If the LED bulbs are at high temperature for a long time, it will shorten the life of the LED bulbs. From the pre-encapsulation and encapsulation, the heat dissipation of the LED chip and the heat dissipation of LED bulbs are considered. The heat dissipation of LED chips is mainly related to the […]

LED light bulbs better than more energy efficient than CFL

LED light bulbs better than more energy efficient than CFL LED lights to consume 25 percent of the energy used in energy saving lamps, because ordinary energy-saving lamps still consume some of the electricity to be converted to heat, and LED lights don’t have that problem. LED lights have a longer lifespan, and quality LED bulbs can last between 10,000 and 20,000 hours, while the same energy-saving lamps can last between 6,000 and 10,000 hours. LED lights are more environmentally friendly. Mercury is one of the indispensable luminescent materials for energy saving lamps. As time goes by, the sealing of energy saving lamps will appear gaps, among which the mercury will evaporate into the air and cause pollution to the air. LED lights are completely free from this problem and are safe and environmentally friendly. LED lights are much better than energy-saving bulbs in terms of anti-seismic and lightning protection. The effect of the continuous switch caused by an unstable voltage  […]

LED bulbs used in families harmful to the eyes?

LED bulbs used in families harmful to the eyes? The LED bulbs with high quality is a good eye protecting eye and does not hurt the eyes. At present, many LED bulbs in the market are of poor quality, which may be harmful to the eyesight of the eyes. The main reasons for unqualified LED bulbs injuries are these aspects: brightness is not enough. Many LED products have a certain degree of hypocrisy about the brightness of the LED lamp, such as the promotion of LED brightness than the same power energy-saving lamp to three to five times higher, and the actual brightness of LED lamps is only equivalent to the same power energy-saving fluorescent lamp about two times. When reading a book, you will damage your eyesight if you use LED lights that are not bright enough. The intensity of LED light is relatively high. It will be glare. Don’t stare directly at the lamp, it is the same as the sun, you say the sun is harmful to the eyes, used as a lamp is good, but the intensity of light is no […]

The United States will impose tariffs on China LED products or will suffer from it

Reading guide: Trump government in July announced a tax project involving a wide range of  China LED bulbs products, including LED lighting category up to more than 10 items. These products account for 75% of China’s total exports of lighting products. In 2017, China’s major lighting products exported to the United States amounted to more than $5 billion. In April 2018, the U.S. government issued a list of 1,300 tariffs on Chinese products, and the U.S. Trade Representative proposed an additional 25% tariff on the list of Chinese products. On July 10, the U.S. Trade Representative’s office issued a statement in which the Trump administration announced a plan to increase tariffs on $200 billion of Chinese goods. In the above two tariff life, China LED bulbs products are impressively listed. The first round of tariff measures for goods exported to China by the United States was launched in July 6th. According to the relevant information, the first list of LED products i […]

Cause analysis of LED dead light

According to the large data of failure analysis, there may be more than 100 causes of LED lamp death, limited to time, today we only take LED light source as an example, starting from the five raw materials of LED light source (chip, bracket, phosphor, solid crystal glue, packaging glue and gold wire), introduce some possible causes of LED lamp death. Today we take the LED dead light as an example to analyze the reasons for this.
