Abstract

The utility model relates to an automatic sensing LED daylight lamp belonging to the technical field of LED lighting. The utility model improves the structure of current LED daylight lamp. A control circuit which comprises light-dependent control and infrared control is disposed at one end of a lamp tube of a circuit board having a plurality of LEDs. When the light luminance lighting on a light-dependent control element in daytime is more than 3LUX, an electron switch is closed no matter an infrared detecting circuit receives an infrared signal sent from human body or not. When the light luminance lighting on the light-dependent control element in daytime is less than 3LUX, the electron switch is opened and the LED light source is lighted if the infrared detecting circuit receives the infrared signal sent from human body. The utility model can continuously switch twice in two seconds in order to realize the two states transition of lighting lastingly and automatically sensing. The utility model has simple structure, can light according to need, further saves energy source and has strong practicability.

Description

The LED fluorescent lamp of automatic induction
Technical field

Background technology
The outstanding feature of led light source is energy-conservation, used by extensive exploitation in recent years, LED is positioned in the pipe to use also as in the past fluorescent lamp and arises at the historic moment, present LED fluorescent lamp generally has two kinds of structures, a kind of is that some LED serial parallel are connected on the wiring board of solid welding in placing pipe, by link plate after one road civil power transformation rectification, another kind is that some LED serial parallel are connected on the wiring board of solid welding in placing pipe, and the multichannel civil power is respectively by link plate after the transformation rectification.The common deficiency that these two kinds of LED fluorescent lamps exist is not open as the light fixture that generally uses now not work, and is not related to and does not put out.Emphasize energetically energy-conservation, especially as these occasions of underground parking, fully can be bright again in the needs illumination, unnecessary Chang Ming does not put out and wastes energy.
Summary of the invention
The purpose of this utility model provides a kind of LED fluorescent lamp of automatic induction, overcomes being not related to of existing LED fluorescent lamp existence not put out the deficiency that wastes energy, and is bright again when being implemented in the needs illumination by the utility model, helps further energy savings.
The purpose of this utility model is achieved through the following technical solutions, a kind of LED fluorescent lamp of automatic induction, comprise fluorescent tube, the wiring board of the some LED of solid welding in the pipe, the plug of lamp tube ends, it is characterized in that fluorescent tube one end is provided with near the plug place and comprises control circuit and power circuit light-operated, infrared control, the source end of power circuit connects the plug of respective end.
The described control circuit of light-operated, infrared control that comprises is by the ambient light detecting head, the infrared signal detecting head that are fixed on the tube wall, the integrated treatment circuit of detectable signal, delay circuit and electronic switching circuit, ambient light detecting head, infrared signal detecting head connect the corresponding signal input of the integrated treatment circuit of detectable signal respectively, the output termination delay circuit of the integrated treatment circuit of detectable signal, the time-delay output of delay circuit connects the electronic switching circuit control end, and the output of electronic switching circuit connects the wiring board of LED.
The integrated treatment circuit of described detectable signal adopts the PT8A2648WE integrated circuit.
Described ambient light detecting head is made of photo resistance and peripheral circuit thereof.
Described infrared signal detecting head is made of the pyroelectricity human-body infrared sensing device of Fresnel Lenses and lens focusing place, and the output of sensor connects the corresponding signal input of the integrated treatment circuit of detectable signal.
Described electronic switching circuit adopts thyristor, and the control utmost point of thyristor connects delay circuit.
The utility model is the improvement to existing LED fluorescent structure, comprise control circuit light-operated, infrared control by fluorescent tube one end setting at wiring board with some LED, when daytime, the light illumination on being radiated at light-dependent control element was greater than 3LUX, no matter whether the infrared acquisition circuit receives the infrared signal that human body sends, electronic switch all cuts out, the utility model is in holding state, and the standby power of this moment is less than 0.15W (not power consumption substantially after tested); Light illumination on being radiated at light-dependent control element is during less than 3LUX, if the infrared acquisition circuit receives the infrared signal that human body sends, this moment, electronic switch was opened, and led light source is lighted, after infrared signal disappears, the utility model will be delayed time and be entered holding state behind the 80s; The utility model starts to control light can be set between 0.5~10LUX according to actual needs, and delay time can be set between 5s~30min, and the setting of delay time realizes by the corresponding resistor of regulating the PT8A2648WE peripheral circuit; The utility model continuous switch in two seconds can be realized long bright and automatic induction two states conversion for twice, the pulse signal that continuous twice utilization of switch produces in two seconds acts on delay circuit and realizes long bright and automatic induction two states conversion. and the utility model is simple in structure, realized in the needs illumination bright again, help further energy savings, have very strong practicality.
