Description
Denomination of invention: the single-ended electric ballast of screw-in
Technical field
The present invention relates to a kind of improved electric lighting device, particularly plug and play, screw-in is convenient for changing formula monofocal electronic ballast for fluoresent lamp.
Background technology
Conventional fluorescent is a kind of efficient, long-lived lighting source, is widely used in room lighting.In in the past 30 years, fluorescent lighting has been experienced from traditional Inductive ballast to electric ballast, the huge innovation from the calcium halophosphate activated by antimony andmanganese to the rare-earth trichromatic fluorescent powder, and system effectiveness has promoted more than 50%.In addition, the functional application of lighting like light modulation and induction, has also obtained very big expansion simultaneously, has promoted worldwide green illumination cause greatly.
Numerous advantages such as electric ballast has efficient energy-saving than traditional Inductive ballast, and volume is little, and is in light weight, and output current ripple and light beats are little, and the proof voltage fluctuation is good.But because the electronic devices and components of its use are numerous, its reliability receives external interference like thunderbolt, voltage fluctuation and ambient temperature, and the influence of mounting condition is bigger.The reliability of electric ballast is not as traditional inductance type ballast under many situation, and electric ballast presents higher early failure ratio.
The circuit of fluorescent lighting fixture is generally semipermanent installation, and whole light fixture need be accomplished in factory, and electrical function is of a great variety, has unnecessarily increased the specification kind of light fixture, brings a lot of troubles for the production and the management of product of light fixture factory.Fluorescent lamp electrical equipment has essential links such as testing and wears out in manufacturing process in addition, needs repeatedly installing/dismounting, even utilize various frock clamps also to waste time and energy relatively.
Contain numerous electronic devices and components in the electric ballast, a spot of early failure is inevitable in actual environment for use.In case electrical equipment lost efficacy, the dismounting of electrical equipment often is difficult in the light fixture, and need employ professional electrician.The cost relevant with electrical equipment can not be ignored in the use of light fixture life-cycle like this.
Most fluorescent lamp appliance lifes are longer, general installing and using under the environment, even a lot of fluorescent lighting fixture needs integral demounting discarded when having arrived life termination.At this moment most of electrical equipment of determining still are intact, can continue to use.But because because inconvenient dismounting and test, the excuse of electrical equipment is nonstandard, causes its versatility to reduce.Thereby can't be reused and become unnecessary electronic waste by unnecessary having abandoned.
Fluorescent lighting fixture and electric equipment products quality are uneven on the market; In general family environment for use, also often occur losing efficacy; And often have to when changing these electrical equipment accomplish by the layman, owing to lack professional electrician's knowledge, the light fixture of repairing has certain potential safety hazard.
Screw-in one end fluorescent lamp electric ballast of the present invention can effectively solve above these problems, and this design is applicable to the Electrical Appliances Designing of led light source too.
Summary of the invention
The present invention has designed a screw-in one end fluorescent lamp electric ballast interface, can supply simultaneously maximum two fluorescent tubes to use, and is applicable to and is no less than 16 kinds of typical fluorescent tubes.
The electrical equipment of the present invention's design can be the repacking of light fixture, regular maintenance, and the electrical equipment recycling, electrical equipment is repaired and the update of light fixture electrical equipment brings great convenience.Avoid the unnecessary replacement of whole light fixture, reduced industrial refuse.
Embodiment:
By the electronic ballast for fluoresent lamp that one or more wiring board has been formed, have three power input terminals and two signal input end (6+, 6-).Three power supply terminal positions are respectively phase line (4 (L)), zero line (4 (N)) and ground wire (5); T type copper post as phase line and zero terminal is welded on the wiring board of electric ballast, ground wire through lead draw with last cylinder on a projection on the arcwall face be connected.
When being positioned at the top towards electrical apparatus interface and ground electrode, the T type electrode on the left side is the phase electrode, and the right side is a null electrode.Two control electrodes are positioned on the peripheral cambered surface of cylinder on the lower half-space, its respectively with the electric appliance circuits plate on control terminal link to each other, these control signals can comprise dc low-voltage signal, DALI signal or pwm signal etc.
Electric current arcuate socket position A-B-C-D-E and voltage waist hole site 1-2-3-4-5 begin at interval from electrode and null electrode mutually respectively clockwise, and 30 degree mark.Have 25 different electric currents and combination of voltages, can mate the fluorescent tube of similar number.
Waist hole site B current corresponding is 170 milliamperes on the last annulus table top, and position C is 320 milliamperes, and position D is 550 milliamperes.Position A and E current corresponding are undetermined.
The corresponding different voltages with different setting of the waist hole site 1-2-3-4-5 of following annulus table top; Unlike the electric current arcuate socket on the last annulus; The central angle that arcuate socket on the following annulus is corresponding can change; When an Electrical Appliances Designing can be used for driving with electric current but during the fluorescent tube of different capacity, the voltage arcuate socket has bigger central angle.
For example, the TL5 two lamp universal electronic ballasts of a dc low-voltage tunable optical, this electric ballast can drive the high light efficiency fluorescent tube of TL5 from 14 watts to 35 watts.
Because high light efficiency T5 lamp works electric current all is 170 milliamperes, current aperture is positioned at position B, in the middle of 14W and the 35W 21 watts and 28 watts of fluorescent tubes is arranged in addition, thereby the voltage hole is set to 1-4, and the arcuate socket of correspondence is the 1-2-3-4 through hole, and its central angle is the 30-120 degree.
Two lamp electronic ballast outputs have seven terminals, and the wiring board output is drawn with the contact at top through lead and realized being electrically connected.These seven contacts are divided into three groups of 2-3-2, are connected to respectively on the corresponding inner conductor of outside appliance contact, two arc grooves are arranged to strengthen electric insulation between adjacent contact sets.
