Description
Technical field
The present invention relates to LED tubular lamp, refers in particular to a kind of both-end LED tubular lamp.
Background technology
Fluorescent lamp is to apply extremely wide traditional lighting light fixture, and existing fluorescent lamp is by High Frequency Electric Ballast, fluorescence
Fluorescent tube, lamp socket, wire, fitting structure part etc. form.Existing LED is by LED lamp tube, constant-flow driver, lamp socket, wire, lamp
Component etc. of signing an undertaking forms.The two is compared, and LED has significant power savings advantages.Therefore, traditional fluorescent lamp is replaced with LED,
It is the certainty for illuminating scientific technological advance.
Traditional fluorescent tube is gas-discharge lamp, can be driven with high-frequency ac power, and LED tubular lamp is single-phase conductive
Diode load, it need to be driven with DC constant flowing power, therefore both type of drive, the mode of connection have very big difference.If
It can accomplish not changing conventional fluorescent light fixture (including retaining original High Frequency Electric Ballast, conductor connections of light fixture etc.)
Under the premise of, directly replace conventional fluorescent fluorescent tube with the LED tubular lamp of same specification (caliber is identical, length is identical), it will greatly reduce
Light fixture update input and save substantial contribution, human and material resources;Simultaneously in view of traditional electronic rectifier of fluorescent lamp
Working life is grown not as LED tubular lamp, after a period of time after LED tubular lamp replaces fluorescent tube, electronic rectifier of fluorescent lamp one
, can when denier fails and changes (because light source updates, traditional electronic rectifier of fluorescent lamp is insufficient or superseded) without like product
From the direct current current-constant LED lamp driver of adaptation, continue to make LED tubular lamp normal work.In this way, LED tubular lamp is set to obtain completely
The use of " life cycle ", client are without fear of an attack from the rear.Therefore, the present invention, which provides one kind, can receive conventional fluorescent electronic rectifier
The high-frequency ac power driving of device output, and can receive the LED tubular lamp of direct current constant current driving, to meet above-mentioned demand.
