Abstract
The invention discloses a LED lamp circuit. The circuit includes a power supply, a switch and a LED lamp, further includes a detecting and controlling unit connected between the power supply and the LED lamp. An AC/DC power converter is connected in between the power supply and the switch. The output end of the AC/DC power converter is connected to the input end of the detecting and controlling unit. The switch is a field-effect tube. The invention has advantages such as simple structure, energy saving, environmental protection, low cost and high rate of utilization.
Description
Technical field
The present invention relates to a kind of LED lighting technology, particularly relate to a kind of LED circuit for lamp.
Background technology
The LED illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through charge carrier compound energy of emitting surplus takes place and causes photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.
The LED advantage such as: one, little, the LED of volume is that a very little wafer is encapsulated in the epoxy resin the inside basically, and is so it is very little, very light; Two, power consumption is low, and the LED power consumption is quite low, DC driven, and super low-power consumption, the equal illumination effect is than conventional light source energy-conservation nearly 80%; Three, long service life, it is the solid cold light source, epoxy encapsulation does not have loosening part yet in the lamp body, do not exist filament light-emitting to be prone to shortcomings such as burning, heat deposition, light decay, and is under appropriate electric current and voltage, longer more than 10 times than the conventional light source life-span; Four, high brightness, low in calories, LED uses the chemiluminescence technology, and caloric value is more much lower than ordinary luminaire; Five, environmental protection, LED is made by nontoxic material, and LED also can recycling; Six, sturdy and durable, LED is encapsulated in the epoxy resin the inside fully, and is all firmer than bulb and fluorescent tube.Do not have loosening part in the lamp body yet, make LED not fragile.
So the increasing home lighting that applies to of LED lighting technology uses.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of LED circuit for lamp is provided, simple in structure, energy-conserving and environment-protective, cost is low, and utilance is high.
In order to achieve the above object; The technical scheme that the present invention adopts is: a kind of LED circuit for lamp; Said circuit comprises power supply, switch and LED lamp; Described LED circuit for lamp further comprises detection and the control unit that is connected between power supply and the LED lamp, between power supply and switch, also is connected with the AC/DC power supply changeover device, the output joint detection of AC/DC power supply changeover device and the input of control unit; Described switch is a FET.
Compared with prior art, the invention has the beneficial effects as follows: simple in structure, energy-conserving and environment-protective, cost is low, and utilance is high.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present invention.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that technical characterictic of the present invention and advantage are carried out more deep annotation.
Theory diagram of the present invention is as shown in Figure 1; A kind of LED circuit for lamp; Said circuit comprises power supply, switch and LED lamp; Described LED circuit for lamp further comprises detection and the control unit that is connected between power supply and the LED lamp, between power supply and switch, also is connected with the AC/DC power supply changeover device, the output joint detection of AC/DC power supply changeover device and the input of control unit.Described switch is a FET.
Operation principle of the present invention is following: after supply voltage inserts, through connecing switch behind the AC/DC power supply changeover device and connecing the LED lamp.Supply voltage one tunnel outputs to detect and control and is input to the power supply of LED lamp after power supply detects voltage and current power etc.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For one of ordinary skill in the art of the present invention, under the prerequisite that does not break away from the present invention's design, make simple change or optimization, all should be regarded as protection scope of the present invention.
