LED light bulb is the most energy saving, a 5 Watt LED bulb is equivalent to 12 watts of energy-saving lamps, 40 watt incandescent lamp. If the amount is large, a year of electricity can be saved back to buy a lamp. Ed lamps and lanterns are generally expensive, compared with the price of energy-saving lamps, white light, etc.. But at present, the development trend of LED lamp is lighting. Because the LED lamp has the advantages of green environmental protection, energy saving, safe advantages and life is white lights woven 10 to 20 times more, under the same illumination light, energy-saving lamps using 30W equal to LED lighting 12w led lamp.

LED lamp basic life is more than 10 years, almost no maintenance. However, it is important to note that the purchase of LED lights do not go to those famous brands, the most important to find those good quality, to pay attention to a few points. 1, a light source (fading) 2, lamps and lanterns (whether good heat dissipation, design, etc.) 3, internal design, circuit board, which can be such as roads, the printed circuit board can see it) 4, the power drive below explain some of the knowledge, in the hope that help 1, a light source: the pros and cons of the light source is led products the main index, good LED products should choose well-known brands of the formal chip package led to you, 1W chip size should not be less than 40ml, 3W chip size not less than 45 mil, with a number of products on the selection of the same brightness, the same band led. Good LED products to meet more than twenty years of life and, within two to three years decay is very small, led in a month or two began gradually appear dead pearl, attenuation is very large, and this phenomenon once is a bulk phenomenon, can not be repaired, only full replacement, works to bring great economic and reputation losses.

There is a very important characteristic in the need to pay attention to: LED light source products are not the more the number of brightness is higher than LED, good poor LED brightness may be a difference of one or two times, the overall high light efficiency of products is a good product, in order to reflect the characteristics of LED such as high power, relative to the LED projection lamp who, under the condition of the same brightness, 24W products have more advantage than the same price 36W products, the service life of 24W products more energy-efficient high-power LED is depends on the light source and drive quality, and it is important to ensure the LED lamp working temperature should be controlled in a reasonable range inside, will produce very high temperature and high power LED work, so it is the key to ensure good heat radiating quality LED life, largely relies on the design of lamps, LED lamps, LED products must use special. LED lamp generally has the following characteristics: material is aluminum alloy (aluminum alloy processing in two ways, one is profile processing, second is die casting, profile processing products than that of die casting forming product density, so the heat dissipation is better), high and thin lamp, four weeks or at the bottom with radiating fins, lamps and lanterns for the structure. 3, internal circuit design
