Advantage of LED bulbs over fluorescent lights

　　LED light bulbs are using of LED chips , the same shape and incandescent light bulbs . Like incandescent bulbs , can be installed on the E26, E17 and other lamp . However, compared with incandescent lamps, can significantly reduce power consumption. Some types of led bulb incandescent bulb power consumption is only 1/5 less . After 2010, more and more areas of the world to ban the use of energy inefficient incandescent lamps , LED bulbs can people expect and fluorescent bulbs together as an alternative to the use of ordinary incandescent .

　　Longer life than compact fluorescent lamp LED bulbs. Longer life fluorescent bulbs only 12,000 ~ 13,000 hours , while the majority of LED bulb life of up to 40,000 hours . Disadvantages bulb -type fluorescent lights can't be instantaneous and just opened lower brightness , etc., and LED bulbs do not have these drawbacks. Overall efficiency of LED light bulbs ( including power circuit , including overall efficiency ) , the bulb color products for 50.60lm / W about daylight as 70.90lm / W or so, and quite compact fluorescent lamp .

　　But there is a small light bulb LED illumination range of issues . Incandescent illumination range of approximately 300 degrees , about 260 degrees fluorescent light bulbs , LED bulbs ordinary only about 120 degrees. Therefore, in addition need to direct the parties themselves irradiation direction side of the lighting apparatus using the LED lamp is not suitable . LED lamp manufacturers through light irradiation direction can be changed using the reflection plate , or increasing the light irradiation surface of the cover in the light diffusing shade , or three-dimensional configuration of LED, the LED lamp can solve the problem of a small range of light .
