Abstract
The utility model relates to a multi-compatible LED driving circuit which belongs to the field of lighting devices. The multi-compatible LED driving circuit comprises an LED tube and is characterized in that the input end of a rectification circuit is connected between the two ends at each side of the LED tube, and the output end of the rectification circuit is connected with the power input end of an LED circuit. The power output end of the LED circuit is connected with the input end of an LED driving power, and the output end of the LED driving power is connected with an LED light source. The LED tube can be used normally with voltage input between any two metallic needles by adding a rectifier bridge, and the action of a starter may not be triggered even when the starter is arranged in a light, thereby reducing work difficulty and safety risk.
Description
Technical field
The utility model relates to field of illuminating device, at length says it is a kind of LED drive circuit of many compatibility modes.
Background technology
As everyone knows, LED illuminating product developed rapidly in recent years, and the raising along with parameters such as light efficiency, aobvious fingers, is widely used.In carrying out reducing energy consumption and light source alternative Process, because the difference of principle of luminosity, LED illuminating product does not need the starter of traditional inductance type fluorescent tube, and the method adopting is at present that starter is taken off, or adopts " starter " of the special use of LED fluorescent tube to substitute.Can there is problem below in conventional method at present: 1, difficulty of construction is large, during reducing energy consumption, need to pull down starter, if it is larger that the starter difficulty of LED special use need to be installed, increased engineering time, cost, special-purpose LED starter has also increased terminal use's use cost simultaneously; 2, the starter installation site of part light fixture easy detachable not, need to disassemble relevant light fixture shell, Gai Caineng and take off starter, increases difficulty of construction; If the light fixture 3, taking off after starter is no longer installed starter, have two circular holes, affect outward appearance, and also easily dust stratification, laying dust, after the time is long, have dust and fall, there is the place of willow catkins flying in the air even can cause the generation of fire.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of LED drive circuit of many compatibility modes, adopt easy scheme cheaply, adopt a set of new circuit arrangement, when carrying out the transformation of inductance type daylight lamp energy-saving, do not need to change circuit, do not need to take off starter, technique is simpler, and product reliability is higher.
The utility model solves the technical scheme that its technical problem adopts: a kind of LED drive circuit of many compatibility modes, be provided with LED fluorescent tube, it is characterized in that, between two terminals of the every side of LED fluorescent tube, connect the input of rectification circuit, the power input of the output termination LED circuit of rectification circuit, the power output end of LED circuit connects the input of LED driving power, the output termination LED light source of LED driving power.
The beneficial effects of the utility model are, by increasing rectifier bridge, input voltage fluorescent tube between no matter any two metal needles of LED fluorescent tube can normally be used, and can not trigger any action of starter there is starter in light fixture in the situation that yet, reduced task difficulty and potential safety hazard.
