Description
Technical field
The utility model relates to a kind of intelligent LED desk lamp, is specifically related to a kind of desk lamp of controlling the illumination intensity of LED through infrared remote sensing technology.
Background technology
The raising of the Along with people's level of consumption and quality of life, people are also increasingly high to the demand of desk lamp.In work with during rest, the brightness of desk lamp there is different requirement.When work,, usually forget and close desk lamp, waste energy because other things are left.The LED lamp of existing adjustable brightness joint needs to use inconvenient through manual adjustments mostly.
Summary of the invention
The purpose of the utility model is the defective that exists in the prior art in order to solve, and a kind of LED desk lamp of can intelligence regulating brightness is provided.
In order to achieve the above object, the utility model provides a kind of intelligent LED desk lamp, comprises lamp socket and is located at the LED lamp on the lamp socket, and the LED lamp is an adjustable brightness LED lamp; This intelligent LED desk lamp also comprises pyroelectric infrared sensor and single-chip microcomputer; Pyroelectric infrared sensor and single-chip microcomputer all are located in the lamp socket; The input of single-chip microcomputer links to each other with pyroelectric infrared sensor, and output links to each other with the LED lamp; The LED lamp adopts the constant-current driving controller to control.
Wherein, single-chip microcomputer adopts the STC12C5410AD that carries EEPROM; It is the DC-DC converter of core with the FET IRF3710 of low on-resistance that the constant-current driving controller is adopted as employing.
When the people got into the surveyed area of pyroelectric infrared sensor, pyroelectric infrared sensor sent a signal to single-chip microcomputer, by Single-chip Controlling LED lamp preset higher intensity of illumination was provided; When the people left the surveyed area of pyroelectric infrared sensor, pyroelectric infrared sensor sent a signal to single-chip microcomputer, preset lower intensity of illumination is provided or is closed the LED lamp by Single-chip Controlling LED lamp.
The utility model is compared prior art and is had the following advantages: utilize pyroelectric infrared sensor to detect, under different patterns, by Single-chip Controlling LED lamp different illumination brightness is provided; Adopt the constant current control technology simultaneously, brightness constancy when guaranteeing desk lamp work overcomes because the lighting quality decline problem that the supply network fluctuation brings.Carry EEPROM through single-chip microcomputer, the intensity of illumination under the different mode that carries out personal set is carried out parameter preserve, realize memory function.
Description of drawings
Fig. 1 is the structural representation of the utility model intelligent LED desk lamp:
Among the figure, 1-LED lamp, 2-lamp socket, 3-pyroelectric infrared sensor, 4-single-chip microcomputer, A: test point.
Fig. 2 is this practical intelligent LED lamp main control process flow sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to Fig. 1, the utility model intelligent LED desk lamp comprises LED lamp 1, lamp socket 2, pyroelectric infrared sensor 3 and single-chip microcomputer 4.LED lamp 1 is the LED lamp of adjustable brightness, is located on the lamp socket 2.In order to practice thrift the size of lamp socket, power supply directly disposes external power supply.LED lamp 1 adopts the constant-current driving controller, and brightness constancy when guaranteeing desk lamp work through the constant current control technology overcomes because the lighting quality decline problem that the supply network fluctuation brings.The constant-current driving controller is the DC-DC converter of core for adopting the FET IRF3710 with low on-resistance.Pyroelectric infrared sensor 3 adopts D203S.Single-chip microcomputer 4 adopts the STC12C5410AD that carries EEPROM.Pyroelectric infrared sensor 3 all is located in the lamp socket 2 with single-chip microcomputer 4.Action through the pyroelectric infrared sensor 3 detection A people of place is sent to single-chip microcomputer 4 with signal.Single-chip microcomputer 4 is controlled the intensity of illumination of LED lamp 1 according to detected signal and preset parameter.
During use, at first according to a human needs, under different mode, set needed intensity of illumination, and setting value is kept among the EEPROM of single-chip microcomputer 4, remember.This setting can be provided with through infrared remote control.Under the reading pattern: in the time of in the people enters into the pyroelectric infrared sensor surveyed area, desk lamp provides the intensity of illumination of the stronger suitable people's reading that presets; When the people leaves surveyed area, desk lamp provide one preset than low light according to intensity, also can use closing function, energy-conservation effect of a step when reaching.Under rest mode: when the people needs rest, can switch to rest mode, desk lamp provides a preset low light of reserving according to intensity, and closes desk lamp during to the fixed time, is particularly suitable for being placed on the child room and uses.Simultaneously when each start, desk lamp is in the reading pattern, and provide one preset than low light according to intensity.
Referring to Fig. 2, intelligent LED desk lamp controller mainly comprises dc supply input, DC-DC converter, constant current voltage output end, current detecting, pyroelectric infrared-sensing, infrared remote control, single-chip microcomputer.
Wherein, constitute constant-current controller together, because that the LED lamp works in constant current brightness of following time is even, constant, so only need carry out current detecting to the output of converter by single-chip microcomputer, DC-DC converter, current detection circuit.When output current is changed; The electric current that promptly flows through the LED lamp changes; Single-chip microcomputer detects through current detection circuit and removes to regulate the DC-DC converter after electric current is dealt into variation, makes output current to opposite vary, thereby guarantees that output current is constant.
The constant current voltage output end is received outside LED lamp.
