Embodiment
Fig. 1 is the AC coupled power supply cross section structure diagram of LED lamp of the present utility model and facing upward for lamp plate part
View.AC coupled power supply LED lamp, including：Lamp body 3, high voltage supply base 1, Low voltage lamp base 2, the and of graphite glue 4
Buckle 5.
High voltage supply base 1 is made up of high-tension transformer 11 and high pressure shell 12, and high-tension transformer 11 is wrapped in outside high pressure
In shell 12, for obtaining energy from line and being transmitted to Low voltage lamp base 2 by wireless transmission method.High-tension transformer 11
It is made up of high pressure magnetic core 111 and the high-voltage isulation enamel-covered wire 112 for being wrapped in the periphery of high pressure magnetic core 111, forms Industrial Frequency Transformer
It is primary.The input range of high-tension transformer 11 is in 200-240V.Due to except high pressure magnetic core 111 and high-voltage isulation enamel-covered wire 112
The outer high-tension transformer 11 does not contain other accurate devices, thus the life-span of the high voltage supply base 1 can with decades-long,
In building in use, with little need for replacing, although once putting into slightly higher, the maintenance and use cost divided are extremely low.
Low voltage lamp base 2 is made up of low-tension transformer 21 and low pressure shell 22, and low-tension transformer 21 is wrapped in outside low pressure
In shell 22, the energy that is transmitted for collecting high voltage supply base 1, and drive lamp body 3 with the energy.Low-tension transformer 21
It is made up of low pressure magnetic core 211 and the low-voltage insulation enamel-covered wire 212 for being wrapped in the periphery of low pressure magnetic core 211, forms Industrial Frequency Transformer
It is secondary.Because the low-tension transformer 21 does not contain other accurate devices in addition to low pressure magnetic core 211 and low-voltage insulation enamel-covered wire 212
Part, thus the life-span of the Low voltage lamp base 2 can with decades-long, between floors in use, with little need for replacing, though
So once put into slightly higher, but the maintenance divided and use cost are extremely low.
Lamp body 3 is by lamp housing 31, lamp plate 32 and is welded on 33 groups of the multiple LED light emitting diodes connected on lamp plate 32
Into；Lamp body 3 is structure as a whole with Low voltage lamp base 2, and low-voltage insulation enamel-covered wire 212 and LED light emitting diodes 33 are connected, real
Now powered from low-tension transformer 21 to LED light emitting diodes 33.Only have LED light emitting diodes 33 on lamp plate 32, circuit is extremely simple, does not have
There are other devices, powered completely by low-tension transformer 21.
One layer of graphite glue 4 is set between high pressure magnetic core 111 and low pressure magnetic core 211, and graphite glue 4 has the work of conduct magnetic field
With so that high-tension transformer 11 and low-tension transformer 21 form a complete energy-transmission channel.The magnetic conduction of graphite glue 4 but not
Conduction, pressure-resistant reachable 3KV.
When civil power is by high-voltage isulation enamel-covered wire 112, alternation is excited due to being alternating current, therefore in high pressure magnetic core 111
Magnetic field, the magnetic field is coupled on low pressure magnetic core 211 by graphite glue 4.High voltage supply base 1 and Low voltage lamp base 2 pass through
Buckle 5 is combined closely, and the gap of high pressure magnetic core 111, low pressure magnetic core 211 and the three of graphite glue 4 is smaller, and the effect of coupling is better,
Energy utilization efficiency is higher, it is preferable that the gap of high pressure magnetic core 111 and low pressure magnetic core 211 is less than 0.2mm, more selects gap small
In 0.4mm.Buckle 5 is made of nylon material that strengthening, can bear 5KG power.The alternating magnetic field being coupled on low pressure magnetic core 211
Low-voltage AC is produced in low-voltage insulation enamel-covered wire 212, the low-voltage AC flows to lamp body 3.The He of low-voltage insulation enamel-covered wire 212
The LED light emitting diodes 33 of lamp body 3 are connected.The forward voltage of LED light emitting diodes 33 about 3V, backward voltage about 10V, therefore
LED light emitting diodes 33 end in negative half-wave in positive half-wave forward conduction, and LED light emitting diodes 33 also correspond to diode
Rectified action.
High-voltage isulation enamel-covered wire 112 and low-voltage insulation enamel-covered wire 212 have respective coil turn and resistance value.It is actual to answer
In, the structure of high voltage supply base 1 is immobilized, and different parameters can be lighted by the parameter for changing Low voltage lamp base 2
Lamp body 3, therefore Low voltage lamp base 2 must and the 3 supporting installation of lamp body.That is the operating current of LED light emitting diodes 33
Determined by the low-voltage insulation enamel-covered wire 212 of low-tension transformer 21.Preferably, the output voltage range of low-tension transformer 21 exists
12-14V, output current 0.3A-0.35A, there is certain invariable power to act on.
Calculation formula：
Output voltage/input voltage=212 coil turns of secondary low-voltage enamel insulated wire/primary high pressure enamel insulated wire
112 coil turns
The LED lamp is preferably Down lamp.When installation, first installation fixes high voltage supply base 1, then by Low voltage lamp
Base 2 (and the one of lamp body 3) up one pushes away, it is possible to will fix lamp body 3 and Low voltage lamp base 2 by buckle 5.Should
Light fixture dismounting is also very simple, the pine of buckle 5 one.
In light fixture of the present utility model, high voltage supply base 1 is fixed on inside ceiling, connects 220V civil powers, people can not
Touch.High voltage supply base 1 connects with Low voltage lamp base 2 without circuit, is completely transferred to city's electric flux by magnetic field
So no matter such as Low voltage lamp base 2, Low voltage lamp base 2 connect with the circuit of lamp body 3 again, light LED light emitting diodes 33,
What Low voltage lamp base 2 and lamp body 3 are all without there is electric shock risk.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model, for those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms, all embodiments can not be exhaustive here,
It is every to belong to obvious changes or variations that the technical solution of the utility model is extended out still in of the present utility model
The row of protection domain.
