Abstract

The utility model relates to a fully automatic night-light, belonging to a lighting appliance. The utility model comprises a pyroelectric infrared automatic control circuit, and a light bulb is loaded in a casing; the casing and the part which is corresponding to a pyroelectric sensor and a photoresistor Gm are respectively provided with light passing holes, and a shielding cover and a Fresnel lens are inlaid on the hole of a heat releasing electric sensor; the light cover is loaded on the casing. The utility model has the advantages of compact structure, good integrity and stable and reliable performance and can be convenient for people to go upstairs and downstairs and to open door locks, and the energy is saved; the utility model is a more ideal door light for every family in a residential district.

Description

Full-automatic night-luminescent lamp

The utility model relates to a kind of full-automatic night-luminescent lamp, belongs to ligthing paraphernalia, is particularly suitable for residential building exterior door front lit dress and uses.

Illuminating lamp all is not set in the corridor of residential quarters in the past usually, gate light also is unkitted in each family, like this during night not only stair activity walk unsteadily very inconvenient, careless slightly, not to bump against on the foreign material of placing in the corridor or to happen occasionally by card situation yet, and open the door and look for keyhole also very not smooth, based on above-mentioned situation, be equiped with the rpyroelectric infrared autocontrol switch in the corridor of the residential quarters that have in recent years, oneself installs bulb to need resident family, thereby the black corridor problem that is through with and never solves is provided convenience for people's life, but also has some unsatisfactory shortcomings, then these layer three tame gate lights are bright entirely as enter the corridor as people one, postpone to extinguish behind the certain hour, the sky that electricity has is also not black just to begin bright lamp, and this must cause the waste of the energy.

The purpose of this utility model is to provide a kind of compact conformation, saves the energy, only when darkness need be thrown light on, when the people goes to oneself automatic bright lamp just 0.5 meter time the in front of the door, is deferred to the full-automatic night-luminescent lamp that the scheduled time extinguishes automatically.

The purpose of this utility model realizes by the following technical solutions, form by a rpyroelectric infrared automatic control circuit, its bulb is loaded in the housing, housing is having loophole with pyroelectric sensor, the corresponding position of photo resistance Gm, and on the hole at pyroelectric sensor place, being installed with radome and Fei Nieer lens, lampshade is loaded on the housing.

The utility model compared with prior art, owing to organically make up as a whole the circuit board of rpyroelectric infrared automatic control circuit and housing, bulb places in the housing, again at housing and pyroelectric sensor, the corresponding position of thermistor has loophole, the former is the insert radome on the hole, the Fei Nieer lens, make it dwindle effective control range, it is unclear that the latter makes it work as blurred vision, promptly just work at dark, and the compact conformation good integrity is arranged through evidence, stable and reliable for performance, walk close to (0.5 meter) automatic bright lamp in its effective control range when needing illumination, postpone to extinguish automatically about 30 seconds, not only facilitating going upstairs and going downstairs with open the door lock but also save the energy.

Fig. 1 is a main TV structure schematic diagram of the present utility model.

Fig. 2 is a plan structure schematic diagram of the present utility model.

Fig. 3 is a side-looking structural representation of the present utility model.

Fig. 4 is the circuit theory diagrams of rpyroelectric infrared automatic control circuit of the present utility model.

Embodiment of the present utility model is described in conjunction with the accompanying drawings, housing 3 is with injection molding, the circuit board 4 of rpyroelectric infrared automatic control circuit is loaded on the side in the housing 3, bulb links to each other with a, the b point of rpyroelectric infrared automatic control circuit, and be loaded on the lamp bracket 2, housing 3 is having loophole with the corresponding position of photo resistance Gm5, with guarantee the control circuit operating part natural daylight reach certain darkness promptly at dark just conducting wait for and devoting oneself to work at any time; Housing 3 is having through hole with pyroelectric sensor 6 corresponding positions, and is installed with radome 7, Fei Nieer lens 8, so that its effective control range narrows down in 0.5 meter, lampshade 1 is loaded on the housing 3.

When the utility model uses, owing to be provided with the natural daylight control circuit, the IC of this circuit in the automatic control circuit ₃9 pin link to each other with photo resistance Gm5, change in resistance takes place in the power with light, nature light intensity resistance change on daytime ambassador operating part is in cut-off state, when natural daylight reaches certain darkness promptly at dark, resistance diminishes and the operating part conducting is waited for devote oneself to work at any time, and come into corridor as the people this moment, when 0.5 meter of the effective control range that reaches pyroelectric sensor 6 should family's gate light bright automatically, and other family's gate lights do not work, and postpone to extinguish automatically about 30 seconds; When natural daylight reaches certain brightness is sight line when high-visible, and operating part ends, thus do not work daytime, and then realize goal of the invention.

Claims

A kind of full-automatic night-luminescent lamp, form by a rpyroelectric infrared automatic control circuit, it is characterized in that bulb is loaded in the housing 3, housing 3 is having loophole with pyroelectric infrared sensor 6, the corresponding position of photo resistance Gm5, and on the hole at pyroelectric sensor place, being installed with radome 7 and Fei Nieer lens 8, lampshade 1 is loaded on the housing 3.
