LED light bulb is better than incandescent lamp

LED lighting applications has attracted much attention, what time LED lighting will replace traditional incandescent bulbs (40 watts), attention. Study on LEDinside market research institutions show that although the LED bulb at the present stage of color rendering, beam angle characteristics are not as good as the traditional incandescent lamp, the initial purchase cost price is still much higher than incandescent lamps, but if used in conjunction with life, luminous efficiency, electricity consumption and other projects, LED lighting has been better than the price incandescent lamp. LED light bulb color specifications, according to the requirements of the U.S. Department of energy, color LED lighting products (CRI) should be more than 80, South Korea's KS requirements of CRI in more than 70. At present, the major brands of the launch of the LED bulb, the basic color have been staged have reached the national standards requirements. Only if compared with the traditional incandescent lamp, LED bulb color is still not as good as the traditional incandescent lamp. From beam angle (distribution properties of light) specifications to view, LEDinside pointed out that the current LED bulb products manufacturers to launch, the difference of beam angle specifications, these claims can replace 40 watt incandescent bulb LED, beam angle from 120 degrees to 260 degrees are more than 2 times the gap. If the United States Bureau of energy and the Japanese chemical industry association will be based on the specification requirements, GE, Philip, Toshiba have been introduced to the beam angle of 250-260 degrees LED bulb products, in line with the requirements. However, if only to, to replace the traditional incandescent lamp standards, these goods are not qualified in principle. Because the light distribution of the incandescent lamp is not a directional light source, the beam angle is greater than 300 degrees, which is different from the LED lamp's luminous characteristics (point light source). It is in terms of price, although the specification conforms to replace the traditional incandescent lamp LED lighting products, the initial purchase price cost is still relatively high, but if used in conjunction with life, luminous efficiency, electricity consumption and other projects to evaluate LED lighting products price, has been compared with the traditional incandescent lamp, appear a relative advantage. For example, 1 of incandescent lamp life is 1000 hours a day, 3 hours 1 light, incandescent lamp can be used for one year (3 hours x365 day about 1000 hours), the total cost of about $5.5 (including the initial purchase cost plus lighting electricity). The 1 LED lamp life of up to 25000 hours, that is, the use of the life expectancy of the LED bulb is about the same as the use of 25 watt incandescent lamp 40. In this regard, the use of LED lighting will be only 40% of the total cost of incandescent lamp program (to the United States as an example of electricity prices) (). In addition, due to the different price, the cumulative total cost for the use of LED lighting and incandescent lighting, will have different effects. For example, in the high cost of electricity in Japan, the total cost of the purchase and use of 1 LED bulbs, is only about 25 of the use of 40 watt incandescent lamp. In other words, when a user buys third incandescent bulbs, the cost of the total cost is higher than that of the LED bulb. Overall, LEDinsid believes that although many manufacturers claim that the LED can replace the traditional lamp 40 watt incandescent lamp, but truly meet the specifications and to replace the threshold LED bulb, or a few. The initial purchase price is much more expensive than incandescent bulbs in these LED bulbs. However, if coupled with LED lamp life, efficiency and other characteristics, the cost of LED bulbs has been better than incandescent lamps.
