Abstract

The utility model discloses an induction lamp, which includes a lamp shade, a lamp holder, a light source and a power supply. The light source is fixed on the lamp holder, and the light source is covered by the lamp shade. The induction lamp is characterized in that a pyroelectric sensor and a circuit control module are connected in series between the light source and the power supply, and a through hole corresponding to the pyroelectric sensor is formed on the lamp shade. In the utility model, the pyroelectric sensor and the circuit control module are connected in series between the light source and the power supply, the pyroelectric sensor is used for detecting signals and sending to the circuit control module, and the circuit control module is used for processing the received signals, so that the light source can be controlled to be turned on or off, the lamp can be automatically turned off when nobody uses, and the waste of electricity energy is avoided.

Description

A kind of sense light

Technical field

The utility model relates to a kind of illuminations, is specifically related to a kind of sense light.

Background technology

In daily life and work, light fixture is applied in various places widely as a kind of illuminations.The light fixture product of Shi Yonging in the market, it all is the light fixture that only has single illumination functions, its structure generally is made up of light source, lampshade, lamp socket, power supply and gauge tap, light source generally all adopts incandescent lamp tube, LED fluorescent tube or other luminous lamp tube, the outside is arranged with lampshade, light source is fixed on the lamp socket, lamp socket is installed on wall or the roof, light source is connected with power supply by gauge tap, thereby press gauge tap when need using and make power supply and light source conducting illumination, make power supply and light source disconnection lighting-off thereby press gauge tap when not using again.Though this class light fixture can effectively throw light on; but must could realize opening or closing of lamp lighting by people's manual manipulation gauge tap; in the use of reality, there is bigger deficiency like this; go out for drill play time such as the student; people are busy when leaving situation such as indoor, and people forget through regular meeting and turn off gauge tap, thereby cause light fixture to be in illumination condition always; certainly will cause waste of electric energy like this, and also be a kind of loss to light fixture simultaneously.

Summary of the invention

The utility model purpose provides a kind of sense light, by the improvement to structure, makes light fixture can close automatically in unmanned, has avoided waste of electric energy.

For achieving the above object, the technical solution adopted in the utility model is: a kind of sense light, comprise lampshade, lamp socket, light source and power supply, described light source is fixed on the lamp socket, described lampshade is sheathed on outside the light source, be in series with pyroelectric sensor and circuit control module between described light source and power supply, corresponding described pyroelectric sensor offers through hole on lampshade.

Further technical scheme, described circuit control module comprises the signal processing module that is connected with described pyroelectric sensor signal output part, is connected with the delay circuit module with described signal processing module.

In the technique scheme, described light fixture is generally to use at present, comprise lampshade, lamp socket, light source and power supply, light source is fixedly connected on the lamp socket, can adopt LED lamp or incandescent lamp, the outside sheathed lampshade of light source, on lampshade, offer through hole, pyroelectric sensor is set in the through hole, detecting element is housed in the pyroelectric sensor, human body has stationary temperature, thereby can send the infrared ray of specific wavelength, and generally the front end at pyroelectric sensor also is equiped with a Fresnel Lenses, these lens and detecting element cooperate, signal can be amplified, thereby can detect the action of people in 10 ~ 20 meters scopes, the signal that detects receives and handles and then the control light source is opened and closed through the circuit control module, the circuit control module comprises signal processing module and delay circuit module, signal processing module is used to accept to handle the signal that pyroelectric sensor sends, and signal is passed to the delay circuit module, and the delay circuit module is used for time-delay closing light source when pyroelectric sensor is surveyed less than human body signal.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1, since the utility model by in pyroelectric sensor and the circuit control module of connecting between light source and power supply, pyroelectric sensor is used for detectable signal and passes to the circuit control module, the circuit control module is handled to the received signal, thereby opening or closing of control light source, make light fixture in unmanned, close automatically, avoid waste of electric energy, and reduced the loss of light fixture;

2, the utility model need not change on a large scale to existing fitting structure, is easy to realize;

3, the utility model is simple in structure, and is easy to use, is fit to promote the use of.

Description of drawings

Fig. 1 is the circuit diagram of the utility model embodiment one.

Wherein: 1, light source; 2, power supply; 3, pyroelectric sensor; 4, circuit control module.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: referring to shown in Figure 1, a kind of sense light, comprise lampshade, lamp socket, light source 1 and power supply 2, described light source 1 is fixed on the lamp socket, described lampshade is sheathed on outside the light source 1,2 of described light source 1 and power supplys are in series with pyroelectric sensor 3 and circuit control module 4, corresponding described pyroelectric sensor 3 offers through hole on lampshade, described circuit control module 4 comprises the signal processing module that is connected with described pyroelectric sensor signal output part, is connected with the delay circuit module with described signal processing module.

Sense light in use, in the time of in people's process investigative range of pyroelectric sensor 3, human body discharges infrared ray and is detected by pyroelectric sensor, pyroelectric sensor 3 received signals also are passed to circuit control module 4, and then control the opening of light source, after the people left the pyroelectric sensor investigative range, pyroelectric sensor was surveyed less than signal, closed behind the delay circuit module controls light source time-delay certain hour in the circuit control module.
