Description
Technical field
The present invention relates to a kind of LED lamp tube, specifically a kind of security strong, repacking high, compatible
The LED lamp tube of the tool linkage self-recoverage turn-off function of low cost.
Background technology
Energy-conservation sustainable development is the theme of world today's development.New light sources illumination with LED as representative takes
For conventional light source, it has also become the trend of illuminating industry future development.This new light sources illuminating product is innovated
Constantly realize under the driving of technology updating, incandescent lamp in early days develop into current LED, shine
Bright product, while realizing upgrading, is also the most well promoted in comfort level and perception, illumination
Effect the most more variation.The relatively conventional illuminating product of Novel LED lamp has energy-conserving and environment-protective, safety
Property height, length in service life, luminous efficiency and colour rendering advantages of higher.According to illuminating product leader philips
Adding up the current whole world has 12,000,000,000 conventional fluorescent to need to replace.
Traditional fluorescent lamp has been required for ballast and has been driven, and current LED is all by exchange city
Electricity directly drives, and when using LED to replace conventional fluorescent, will destroy original florescent lamp fitting system
System makes LED lamp directly to use in old fluorescent lamp system, can only take down the original ballast of fluorescent lamp,
It is revised as directly by city's electric drive.But circuit amendment will be brought problems with:
1, huge improvement cost: as a example by Europe, the circuit of amendment light fixture needs the accredited electrician of specialty,
The expense that the manpower comparing of accredited electrician purchases LED lamp pipe is the highest, thus results in improvement cost the highest.
2, transformation efficiency is low: the accredited electrician with specialty is only capable of transforming 7 tubes for one hour.
3, the Safety Approval of the original light fixture destroyed: the U.S. and the fluorescent tube safety standard requirement in Europe at present:
LED lamp tube is necessary for single-ended power, but conventional fluorescent fluorescent tube is by both end power supplying, demand based on market,
Safety Approval mechanism amendment safety standard is with both end power supplying, but to require when fluorescent tube is accessed in one end, the other end
Not charged, and the pressure of 3750V can be reached, to ensure safety, due to the ballast of conventional fluorescent fluorescent tube
Two ends for fluorescent tube power, according to single-ended power mode, then cannot compatible traditional ballast, to compatibility
Conventional fluorescent ballast must use two ends power supply mode, therefore cannot meet the requirement of safety standard, and which exists
The biggest risk.
