Abstract
The invention discloses a ceiling lamp comprising a controller, an LED lamp, a thermopile infrared sensor, a delay circuit, a relay, a non-self-locking switch and a power supply device. The controller is connected with the thermopile infrared sensor, the delay circuit, the relay and the non-self-locking switch. The thermopile infrared sensor senses whether or not a person stays in a kitchen and sends the data to the controller. According to the data sensed by the thermopile infrared sensor, the controller judges that no one stays in the kitchen and controls the delay circuit to work. During delay, if no person is sensed, the controller controls the relays to stay in an off state. The ceiling lamp can sense whether or not a person stays in the kitchen and can be automatically off after the person leaves the kitchen, automatic degree is increased, electric power is saved, and domestic cost is lowered.
Description
Technical field
The present invention relates to Lighting control field, particularly a kind of ceiling light.
Background technology
The lighting of current use, the fluorescent light source that major part uses.Fluorescent material in fluorescent lamp, has heavy metal and radioactivity, can endanger the healthy of people with human contact.Fluorescent lamp is short for useful life, makes troubles to the use of people.Further, when not needing too large brightness, the brightness of fluorescent lamp cannot be regulated in time, cause unnecessary electric consumption.
In daily life, time light is bad, people enter kitchen needs out kitchen illuminating lamp, but when leaving kitchen, often forget and turn off the light, when by the time remembering, just find the illuminating lamp light yellow always in kitchen, this is wastes power not only, too increases the daily expenditure of family.
Application number is the rechargeable LED bedside lamp that the Chinese patent " a kind of rechargeable LED bedside lamp of the brightness-adjustable that can automatically close " of CN201010527742.1 discloses a kind of brightness-adjustable that can automatically close, and this lamp mainly comprises LED lamp holder, rechargeable battery, charging plug, timer, lamp body etc.It is characterized in that LED lamp holder is connected to lamp body upper end, rechargeable battery, charging plug lay respectively in lamp body, and by-pass cock, timer are positioned at lamp body surface.Being charged to rechargeable battery by charging plug can be bedside lamp electric energy supplement, by regulating by-pass cock to change lamplight brightness, realizing timing turn off the light by the time setting timer.
But there is following problem in this invention: timing can only be realized by the time of setting timer and turn off the light, the function of automatically turning off the light cannot be realized.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of ceiling light, it comprises: comprise controller, LED, thermopile infrared sensor, delay circuit, relay, non-self-lock-ing switch and supply unit, described LED, thermopile infrared sensor is arranged in kitchen, described controller respectively with thermopile infrared sensor, delay circuit, relay is connected with non-self-lock-ing switch, described supply unit respectively with controller, LED, thermopile infrared sensor, delay circuit, relay is connected with non-self-lock-ing switch, whether there is people in described thermopile infrared sensor sensing kitchen and send data to controller, described controller controls delay circuit work when judging nobody according to the data that thermopile infrared sensor senses, between time delay, if still do not sense people, control described relay and be off state.
Described non-self-lock-ing switch is for realizing the switch of Non-follow control LED.
Preferably, described controller is single-chip microcomputer.
Preferably, it is characterized in that, described controller is FPGA.
Preferably, it is characterized in that, described controller is hardware circuit.
