Description

A kind of brightness can the light fixture that regulates of two-way Lazer

Technical field:

The utility model relates to a kind of lamp lighting control method, belongs to lighting field, is particularly useful for the control of LED lamp brightness.

background technology:

At present, LED is due to long service life, energy consumption is low, be applied widely, at the prison, also there is application prison room, the illumination of prison room belongs to a particular surroundings, need for supervision safety and video monitoring, prison room lighting needs more than 10 of evening hour to be in normal bright state, even if employing LED, long-time illumination also can strengthen the electric cost of prison administration, simultaneously, long-time illumination can have a strong impact on the sleep quality of convict and healthy, thus affect convict's work performance of second day and mood, if things go on like this, not only affect the healthy of convict, also affect correctional effect.Part prison is this problem of reply, adopts light and shade two kinds of light sources to be thrown light in prison room, like this, needs manually to be controlled, and increases the cost of light fixture.

summary of the invention:

For overcoming the problems referred to above, the utility model aims to provide a kind of intelligent control method that effectively can realize two-way gradual change to LED light source brightness.

Meanwhile, according in light fixture induction range, receive induced signal according to the inductor that light fixture carries, judge the situation of physical activity in environment, according to physical activity situation, the duration of each brightness of Based Intelligent Control.

A kind of control method with an automatic light meter,

The control method of brightness; Comprise LED, single-chip microcomputer, sensing element, signal amplifier, photo resistance, constant-current driving power supply, circuit, sensing element is connected with single-chip microcomputer by signal amplifier, single-chip microcomputer is connected with control circuit, and disconnected by single chip machine controlling circuit or close, single-chip microcomputer is write-in program in advance, enter with light fixture when being the diameter 8m internal induction investigative range in the center of circle when there being people, single-chip microcomputer receives the induced signal of inductor, and LED is lighted by closed circuit; To leave and after countdown time of delay set terminates 30 seconds, LED is adjusted to 20% brightness automatically, is also adjustable to other brightness when people passes through induction investigative range.When people enters in induction investigative range, after LED is lighted, as people rests in induction investigative range always, before countdown time of delay of setting terminates, very important person has slight movement, and comprise the motion of limbs, driving LED lamp is continued maintenance 100% brightness by inductor, until personnel activity reduces to sleep gradually and after setting-up time countdown terminates, load light fixture is gradually secretly adjusted to 20% brightness automatically.

The utility model also has multiple light to arrange selection, can sets itself as required, after photo resistance receives different photoinduction signals, start LED, to adapt to the lighting demand in varying environment light situation, as early morning, noon, at dusk, dusk, night or whenever.

The control method of sensitivity: set highly sensitive state and low sensitive state in single-chip microcomputer.In highly sensitive state, control single chip computer, to radar signal, keeps highly sensitive reaction, and the less signal receiving radar sense element senses and arrive, had both kept normal bright state, thus kept highly sensitive state; In low sensitive state, control single chip computer, to radar signal, keeps low sensitive reaction, and the more signal receiving radar sense element senses and arrive, just keeps low bright state, thus keep low sensitive state.

Simultaneously, in order to tackle convict when supervising indoor study, be in the movable sight reduced, this LED also can install dimmer switch, be divided into high light shelves and low light level shelves, when convict learns, LED is got to high light shelves, by LED to maximum and keep 100% brightness, for flabellum during the use fan of the reply room of prison in summer is on the impact of light fixture, LED can be got to low light level shelves, when convict's sleep, light fixture is adjusted to the weak brightness of 20%, triggering light fixture is not affected by lasting rotating objects such as fans, by the cooperation of switch dimming and intelligent-induction light modulation, the various situations of lamp light-regulating is taken into account prison room, prison, produce a desired effect and object.

The beneficial effects of the utility model are: the use of this automatic light modulating method, not only effectively can control light-source brightness, Based Intelligent Control can also be realized to the control time of brightness each in light source, and can adopt and control manually, there is the technique effect of energy savings, environmental protection, and easy to use.At the prison or need keep warning occasion use, can alarm function be played; Use in family, needs to be got up personage night, does not need to grope switch in night, facilitate rise night.

accompanying drawing illustrates:

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is fundamental diagram of the present utility model.

In figure: 1 lamp socket, 2 induction modules, 3LED lamp connector, 4 circuit connectors, 5LED light source.

Embodiment:

The control method of brightness; Microwave sensor in induction module 2 is connected with single-chip microcomputer by operational amplifier, single-chip microcomputer is connected with control circuit, strong and weak by electric current in single chip machine controlling circuit, single-chip microcomputer is write-in program in advance, when there being people to enter induction investigative range (in diameter 8m), single-chip microcomputer receives the induced signal of microwave sensor, increases the electric current in circuit, LED 5 is brightened; To leave and after countdown time of delay set terminates 30 seconds, LED 5 is adjusted to 20% brightness (being also adjustable to other brightness) automatically when people passes through induction investigative range.When people enters in induction investigative range, after LED 5 is lighted, as people rests in induction investigative range always, before countdown time of delay of setting terminates, very important person has slight movement (comprising the motion of limbs), driving LED lamp 5 is continued maintenance 100% brightness by induction module 2, until personnel activity reduces to sleep gradually and after setting-up time countdown terminates, load light fixture is gradually secretly adjusted to 20% brightness automatically.

The utility model also can provide multiple light to arrange selection, can sets itself as required, after photo resistance receives different photoinduction signals, start LED, to adapt to the bright light demand in varying environment light situation, as early morning, noon, at dusk, dusk, night or whenever.

The control method of sensitivity: highly sensitive state and low sensitive state will be set in the single-chip microcomputer in induction module 2.In highly sensitive state, single-chip microcomputer, to microwave signal, keeps highly sensitive reaction, and the less signal receiving microwave sensor and sense, can keep normal bright state; In low sensitive state, single-chip microcomputer, to microwave signal, keeps low sensitive reaction, and the more signal receiving microwave sensor and sense, just keeps low bright state.

Simultaneously, in order to tackle convict when supervising indoor study, be in the movable sight reduced, the light fixture that this two-way Lazer regulates also can install dimmer switch, be divided into high light shelves and low light level shelves, when convict learns, LED is got to high light shelves, by LED to maximum and keep 100% brightness, for flabellum during the use fan of the reply room of prison in summer is on the impact of light fixture, LED can be got to low light level shelves, when convict's sleep, intensity of light is adjusted to the weak brightness of 20%, triggering light fixture is not affected by lasting rotating objects such as fans, by the cooperation of switch dimming and intelligent-induction light modulation, the various situations of lamp light-regulating is taken into account prison room, prison, produce a desired effect and object.
