Description
Technical field
The utility model relates to a kind of LED lighting device, is specifically related to a kind of circuit connection structure of Grille lamp.
Technical background
Chinese patent CN101865386 discloses the Grille lamp that a kind of power supply separates with fluorescent tube on 20101020th, comprise lamp panel, be arranged at grid in the lamp panel, be arranged at least two LED fluorescent tubes, lampshade, the power supply of grid and lamp panel bottom surface, and the quantity of described power supply is one, and is connected in simultaneously described LED fluorescent tube.Patent description whole light fixture only have a power supply, and drive all fluorescent tubes.
But in the above-mentioned patent, there is following problem: for the output characteristics of driving power, be constant voltage output or constant current output, do not have clear and definite statement in the patent.Can be in parallel according to connecting between the described LED fluorescent tube of patent also, independent on electric.If connect between the LED fluorescent tube so, then the quantity according to the fluorescent tube series connection is different, and the output voltage of driving power is also different.According to existing technology, and the characteristic of LED device as can be known, and driving power is output as constant current CC drive pattern.This pattern can not guarantee current balance between a plurality of fluorescent tubes, particularly when High-current output, has output risk competitive risk between fluorescent tube.The fluorescent tube series connection too much easily makes electric power output voltage surpass the 36V safe voltage in addition, and Grille lamp is II class light fixture, therefore Danger Electric shock risk is arranged, and does not meet the relevant industries standard.If in parallel between the LED fluorescent tube, then the quantity according to the fluorescent tube parallel connection is different, and the output current of driving power is also different.This moment, power supply was output as constant voltage CV pattern.Known by LED device self-characteristic so, the traditional LED fluorescent tube described in this patent does not meet designing requirement.Therefore, when traditional LED fluorescent tube, in parallel between the fluorescent tube, all inadvisable no matter then power supply is output as constant current or constant voltage mode, this kind design is wrong technically in using patent.As described in patent, when using special LED fluorescent tube, connect between the fluorescent tube, and guarantee when fluorescent tube is connected, to break down, guarantee the whole system endure.So at first, the fluorescent tube series connection has and makes electric power output voltage surpass the 36V safe voltage, and lamp panel is II class light fixture, does not meet safety, and the user has Danger Electric shock risk in use; If extreme phenomenon occurs, all short circuits of LED fluorescent tube, and power supply is still at work, then fire-prone.Secondly, special LED fluorescent tube must increase corresponding Material Cost because being provided with special chip in the fluorescent tube.
The LED Grille lamp that also has another kind of technical scheme on the market, i.e. driving power single channel constant voltage output is configured to the Grille lamp that built-in crossing current drives again, and each Grille lamp is parallel way.This kind LED Grille lamp advantage is each Grille lamp in parallel, and the out-put supply of driving power can be accomplished below the 36V SELV.Shortcoming is that any one Grille lamp can not short circuit.If short circuit then or make driving power enter the short-circuit protection state, or makes certain parts heating in the Grille lamp, the danger of breaking out of fire is arranged.
The utility model content
In order to overcome above problem, the utility model provides a kind of circuit connection structure of Grille lamp, and this circuit structure method of attachment is simple, and the relation of being connected in parallel between the Grille lamp causes the break-make of Grille lamp independent, is independent of each other.
For solving above technical problem, the technical scheme that the utility model provides is as follows: a kind of circuit connection structure of Grille lamp, described Grille lamp circuit connection structure comprises power module and at least two Grille lamps, the power module of Grille lamp is output as multiple constant current or constant voltage output, and is separate on circuit connects between each Grille lamp fluorescent tube; Described Grille lamp is electrically connected with the city through power module.
Further, described Grille lamp is connected in parallel on the power module, when any one fluorescent tube short circuit or open circuit, does not affect the work of other fluorescent tubes.
Further, the input voltage of described power module is 96V-265V, and incoming frequency is 47HZ-60HZ, and output voltage is safe voltage.
Further, the fluorescent tube input of Grille lamp is the single-ended input regardless of both positive and negative polarity, its built-in full-bridge circuit.
Further, described power module has excess temperature, input overvoltage, the defencive function of zero load, overload.
The circuit connection structure of this Grille lamp that the utility model relates to, the light fixture of compatible traditional fluorescent light, but do not contain ballast, keep original circuit wiring and lamp bracket lamp socket, just original ballast is replaced by power module, fluorescent tube is replaced by Grille lamp, and the electrical wiring circuit is slightly done change and just can.
Its beneficial effect is as follows:
1, whole LED Grille lamp has and only has a power supply, and can drive the lamp works of whole LED Grille lamp;
2, the LED fluorescent tube that is equipped with is single-ended input, and the fluorescent tube input makes things convenient for user installation regardless of both positive and negative polarity.
3, the driving power of LED Grille lamp is output as multiple constant current or constant voltage output.Be relation in parallel between each fluorescent tube, electric mutual independence.The damage of certain LED fluorescent tube such as short circuit or open circuit or open circuit, does not affect the work of other LED fluorescent tubes.
4, the lamp panel of compatible existing conventional fluorescent and electrical connecting wires mode.The user can realize one drag two according to demand, perhaps one drags three lamp panel transformation.
