Abstract
The utility model discloses a household LED lamp circuit comprising a power supply, a switch, a LED lamp, a detection and control unit connected between the power supply and the LED lamp, and an AC/DC power converter connected between the power supply and the switch. The output end of the AC/DC power converter is connected with the input end of the detection and control unit. The LED lamp circuit further comprises a current-limiting resistor connected between the switch and the LED lamp. The household LED lamp circuit has characteristics of simple structure, energy conservation and environmental friendliness, low cost, and high utilization rate.
Description
Technical field
The utility model relates to a kind of LED lighting technology, particularly relates to a kind of household LED circuit for lamp.
Background technology
The LED illumination namely is led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by charge carrier compound energy of emitting surplus occurs and cause photo emissions in semiconductor, 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 have the easily shortcomings such as burning, heat deposition, light decay of filament light-emitting, 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.There is not loosening part in the lamp body, so that LED is not fragile yet.
So the LED lighting technology more and more applies to home lighting and uses.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of household LED circuit for lamp is provided, and is simple in structure, energy-conserving and environment-protective, and cost is low, and utilance is high.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of household LED circuit for lamp, described 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, also be connected with the AC/DC power supply changeover device between power supply and switch, the output of AC/DC power supply changeover device connects the input of detection and control unit.Described LED circuit for lamp further comprises the current-limiting resistance that is connected between switch and the LED lamp.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, and energy-conserving and environment-protective, cost is low, and utilance is high.
Description of drawings
Fig. 1 is schematic block circuit diagram of the present utility model.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present utility model and advantage are carried out more deep annotation.
Theory diagram of the present utility model as shown in Figure 1, a kind of household LED circuit for lamp, described 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, also be connected with the AC/DC power supply changeover device between power supply and switch, the output of AC/DC power supply changeover device connects the input of detection and control unit.Further, described LED circuit for lamp further comprises the current-limiting resistance that is connected between switch and the LED lamp.
Operation principle of the present utility model is as follows: after the supply voltage access, 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 in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model one of ordinary skill in the art, without departing from the concept of the premise utility, make simple change or optimization, all should be considered as protection range of the present utility model.
