Abstract

The utility model discloses a full-automatic pillar lamp which comprises a pillar body, wherein a light transmission part is arranged on the pillar body, a plurality of groups of electric lamps are arranged in the pillar body in the position of the light transmission part, the plurality of the groups of the electric lamps are connected in an electric loop in the parallel connection form, a proximity switch is connected in at least one branch circuit of the parallel circuit in series, and the induction surface of the proximity switch is mounted on a housing of the pillar body. By adopting the pillar lamp with the structure, when a person is in the vicinity of the pillar lamp, the brightness of the pillar lamp can be kept in normal state; when the person is far away from the pillar lamp, the brightness of the pillar lamp is weakened accordingly. Therefore, the waste of energy is avoided and the normal use of the pillar lamp is not affected.

Description

Full-automatic post lamp

Technical field

The utility model relates to a kind of Landscape Lamp, particularly a kind of full-automatic post lamp.

Background technology

In the gardening view, post lamp is that the light fixture of one is widely used as ornamental and practicality collection.Yet through out-of-date, it is a kind of energy waste that post lamp keeps normal bright state when unmanned, simultaneously also in the service life that consumes post lamp.

The utility model content

The technical problem that the utility model will solve is: a kind of full-automatic post lamp is provided, can responds to people's distance, thus the brightness of automatic control lamp.

In order to achieve the above object, the technical scheme of the utility model employing is:

Full-automatic post lamp; Comprise cylinder, cylinder is provided with the transmittance section, the position in the transmittance section; Be provided with some groups of electric lights in the cylinder; It is characterized in that: said some groups of electric lights are connected in the electric loop with the form of parallel connection, at least one branch road of said parallel circuit, are in series with near switch, are installed on the cylinder shell near the sensitive surface of switch.

Adopt technique scheme, the utility model has reached following beneficial effect with respect to prior art:

Someone is near post lamp the time, and the brightness of post lamp remains on normal condition; As people during away from post lamp, the brightness of post lamp weakens immediately.Can avoid the waste of the energy like this, also not influence the normal use of post lamp.

Description of drawings

Fig. 1 is the structural representation of the preferred implementation of the full-automatic post lamp of the utility model;

Fig. 2 is the circuit diagram of embodiment shown in Figure 1.

The specific embodiment

Below in conjunction with accompanying drawing and preferred implementation the utility model is done further explanation.

What Fig. 1 showed is the structural representation of the preferred implementation of the full-automatic post lamp of the utility model.As shown in the figure, the full-automatic post lamp of this embodiment comprises cylinder 1, and cylinder is provided with transmittance section 2, and 2 the position in the transmittance section is provided with two groups of electric lights (figure is last not to be shown) in the cylinder 1.

What Fig. 2 showed is the circuit diagram of this embodiment.As shown in the figure, two groups of electric light L1, L2 are connected in the electric loop with the form of parallel connection, in electric loop, also are provided with master switch K1.In a branch road of said parallel circuit, be in series with, be installed on the shell of cylinder 1 near the sensitive surface 3 of switch S Q1 near switch S Q1.

Near switch is to utilize displacement transducer the sensitivity characteristic near object to be reached a kind of switch of gauge tap on-off.Shift near switch as object, and when being close to certain distance, displacement transducer has " perception ", switch can move.

In case the people gets in the search coverage, just can be closed near switch S Q1, thus two branch roads of parallel circuit are path entirely, two groups of electric light L1, L2 are all lighted; In case and the people then breaks off near switch S Q1 away from the radiation scope near switch, electric light L1 extinguishes, and only has electric light L2 to keep the state of lighting, and the brightness of post lamp also can weaken.

Preferred said is that the passive pyroelectric formula is near switch near switch sensor.It can sense the specific wavelength of general human body, i.e. infrared ray about 10 μ m, thereby this activity that is particularly suitable for the people near switch.The pyroelectric electric device of switch is installed on the sensitive surface of switch, as the object different with environment temperature near the time, the output of pyroelectric electric device just changes, it is approaching just can to have detected object thus, thereby the switching of gauge tap.

Combine the accompanying drawing and the specific embodiment that the utility model has been done detailed explanation above; But the utility model is not limited to this; The technical staff in any present technique field is in the ken that is possessed; Under the prerequisite of the utility model aim, can make various distortion and modification to it.
