Abstract
LED self -adaptation classroom lamp of adjusting luminance. The utility model relates to an inconvenient problem of LED lamp adjust light intensity in the current classroom is solved to the technique of adjusting luminance of LED classroom lamp. The utility model provides a ware for intelligent control is carried to the light sense signal of sensing to the light sense device, wireless terminal carries the light intensity value that preset is good and gives the intelligent control ware, the light intensity that preset is gone with by light intensity that the intelligent control ware was sensed according to the light sense device carries out the comparison, according to different comparative results, the intelligent control ware transfers light driver to carry 0 -10V's pulse width modulation signal to LED, thereby control LED transfers the electric current of light driver to LED classroom lamp output. The utility model discloses well external environment's light changes, and LED classroom lamp can carry out the invariable illuminance value that intelligent regulation maintain actual environment automatically, has satisfied the required luminance in classroom promptly, reaches the energy can be saved's purpose again, is applicable to the illumination in classroom.
Description
Technical field
The utility model relates to the light regulating technology of LED classroom lamp.
Background technology
According to country " middle and primary schools' classroom lighting and illumination sanitary standard ", for the classroom of the area of standard, routine installs 11 LED classroom lamps.In the process that reality is promoted, due to classroom size difference, the lamp of equal number is caused to be arranged by same mode very large for different classroom difference on effect, for the classroom that area is little, average illumination is higher, causes waste to the energy, for the classroom that area is large, average illumination is on the low side again, does not reach standard.General classroom lamp can not realize self-adapting intelligent and control, because the light intensity that there are the environment such as daytime, night, cloudy day and fine day is all not identical, therefore environmentally different or regulate the brightness of classroom lamp according to actual needs voluntarily, adjustment is compensated to the illumination that classroom requires, make LED lamp more energy-conservation simultaneously, particularly important.
Utility model content
Goal of the invention of the present utility model is the inconvenient problem of LED adjusting light intensity in order to solve in existing classroom, provides a kind of LED self adaptation light modulation classroom lamp.

Embodiment
Embodiment one: present embodiment is described according to Fig. 1, LED self adaptation light modulation classroom lamp described in present embodiment, it comprises it and comprises LED classroom lamp 4, light sensitive device 2, intelligent controller 1, LED dimming driver 3, wireless terminal 5 and Digiplex 6;
The power input of described intelligent controller 1 is connected with 220V AC power;
The power input of described LED dimming driver 3 is connected with 220V AC power;
The control signal output of intelligent controller 1 is connected with the control signal input of LED dimming driver 3;
The light-sensing signal output of light sensitive device 2 is connected with the light-sensing signal input of intelligent controller 1;
The light sensation preset value signal output part of Digiplex 6 is connected with the light sensation preset value signal input part of intelligent controller 1 by wireless terminal 5;
The DC output end of LED dimming driver 3 is connected with the direct-flow input end of LED classroom lamp 4;
Light sensitive device 2 is used for responding to the light intensity of residing environment.
Embodiment two: present embodiment limits further the LED self adaptation light modulation classroom lamp described in embodiment one, and in the present embodiment, light sensitive device 2 is fixed on the surface of LED classroom lamp 4.
Embodiment three: present embodiment limits further the LED self adaptation light modulation classroom lamp described in embodiment one, in the present embodiment, intelligent controller 1, wireless terminal 5 and LED dimming driver 3 are all fixed on LED classroom lamp 4 inside or surperficial.
Embodiment four: present embodiment limits further the LED self adaptation light modulation classroom lamp described in embodiment one, in the present embodiment, intelligent controller 1 is by the pulse width modulating signal control LED dimming driver 3 of 0-10V.
Embodiment five: composition graphs 2 illustrates present embodiment, present embodiment is the control method based on the LED self adaptation light modulation classroom lamp described in embodiment one, in the present embodiment, comprises the steps,
Step one: environmentally required light intensity, the light sensation preset value set by Digiplex is Q, and setting light sensation preset value Q is supplied to wireless terminal 5 by Digiplex simultaneously;
Step 2: light sensation preset value Q is transferred to intelligent controller 1 by wireless terminal 5;
Step 3: light sensitive device 2 senses that the ambient light intensity level of actual residing environment is W, and light sensitive device 2 is transferred to intelligent controller 1 ambient light intensity level W with the form of light-sensing signal simultaneously;
Step 4: intelligent controller 1 couple of light sensation preset value Q and actual environment light intensity value W compares;
As W=Q, intelligent controller 1 does not export control signal;
As W<Q, intelligent controller 1 exports control signal to LED dimming driver 3, now LED dimming driver 3 increases to the electric current of LED classroom lamp 4, thus actual environment light intensity value W is increased, increase to actual environment light intensity value W equal with light sensation preset value Q always;
As W>Q, intelligent controller 1 exports control signal to LED dimming driver 3, now LED dimming driver 3 reduces to the electric current of LED classroom lamp 4, thus actual environment light intensity value W is reduced, be reduced to actual environment light intensity value W equal with light sensation preset value Q always.
As W>Q, intelligent controller 1 exports control signal to LED dimming driver 3, now LED dimming driver 3 reduces to the electric current of LED classroom lamp 4, thus actual light line strength value W is reduced, and is reduced to actual light line strength value W equal with light sensation preset value Q always.
