Figure 23 is the structure chart of the electric system of the freezer of embodiments of the present invention 1.In fig 23,110 and 120 is the first storeroom and the second storeroom respectively.111 and 121 is the door of the first storeroom and the door with the second storeroom respectively.112 and 122 is the door opening and closing testing agency of the first storeroom and the door opening and closing testing agency of the second storeroom respectively, exports the electronic signal corresponding with the open and-shut mode of the door of each storeroom.

113 and 123 are the LED illumination as the first lighting device of the light-emitting component with illumination first storeroom respectively and have the LED illumination as the second lighting device of light-emitting component of illumination second storeroom.LED illumination 113,123, according to the electronic signal of input main control microcomputer 130, carries out the control of lighting or extinguishing.130 is main control microcomputers that the electric system managing freezer controls, there is the function as control device, it is based on temperature information, temporal information, to compressor, fan, heater, cooling switching device shifter output action signal, in addition accept the electronic signal from above-mentioned door opening and closing testing agency 112 and 122, carry out the control of lighting or extinguishing of above-mentioned LED illumination 113 and 123.

Multiple LED is installed on a substrate by LED illumination 113 and 123 respectively, and can be arranged multiple substrate.

131 be to above-mentioned LED illumination 113 and 123 is added lustre to gradually or dim light time ON time of electronic signal or the timer that measures of OFF time, be loaded into the inside of main control microcomputer 130.180 is temperature sensors, exports the electronic signal corresponding with the environment temperature of sensor.Said temperature sensor 180 in order to measure outside air temperature, or in order to measure the temperature etc. of the optional position in freezer, can be provided with multiple.

140 is accept the electronic signal from main control microcomputer 130, controls the compressor control microcomputer of the action of compressor.141 is accept the signal from compressor control microcomputer 140, the compressor of compressed refrigerant.

150 is according to from controlling the electronic signal of microcomputer 130, carries out the fan of change of ON/OFF switching, rotating speed.Said fans 150 makes the cold air flow in freezer, make wind to compressor with promote heat radiation, can be provided with multiple.160 is the electronic signals for accepting from main control microcomputer 130, prevents the heater freezing, condense of freezer each several part, can be provided with multiple.

170 is accept the electronic signal from main control microcomputer 130, switches the cooling switching device shifter of the stream of the cold-producing medium in freezer.

Then, action when using Figure 23 and Figure 24 explanation that LED illumination is added lustre to gradually.First, when the door 111 of the first storeroom 110 is opened, utilize door opening and closing testing agency 112 to detect and the situation that door is opened notify to main control microcomputer 130.

Now, main control microcomputer 130 starts the control of lighting LED illumination 113 gradually.Figure 24 represents an example of the electronic signal that main control microcomputer 130 exports to LED illumination 113.When by door opening and closing testing agency 112, main control microcomputer 130 is notified that door 111 is opened, first export and make LED illumination 113 be the signal of ON in the ON1 time.Then, output makes LED illumination 113 be the signal of OFF in the OFF1 time.

And then, then export and make LED illumination 113 be the signal of ON in the ON2 time.Herein, ON2 time >=the ON1 time.And then, then export and make LED illumination 113 be the signal of OFF in the OFF2 time.Herein, OFF2 time≤the OFF1 time.And then, then export and make LED illumination 113 be the signal of ON in the ON3 time.Herein, ON3 time >=the ON2 time.

And then, then export and make LED illumination 113 be the signal of OFF in the OFF3 time.Herein, OFF3 time≤the OFF2 time.Like this, the ON time is increased gradually, the OFF time is reduced gradually, finally become and be always ON, make LED illumination 113 add lustre to gradually thus.The LED illumination of the second storeroom is also same.

Then, use Figure 25 that the method that a shared timer makes the LED illumination of two storerooms add lustre to gradually is described.First, when the door 25 of the storeroom of one party was opened in the moment of the time Ts of figure A, before time of advent Te, the LED illumination of this storeroom is increased light quantity according to the ON/OFF figure of Figure 24 gradually by controlling, after time Te, electronic signal is always ON, and LED illumination becomes illuminating state with maximum brightness.

In this control, timer 131 in order to measure each ON time of Figure 24 and each OFF time, during time Ts to time Te, ceaselessly perseveration.The door 25 of the opposing party sometime when between this time Ts to time Te is opened, timer 131 is in order to carry out the control (add lustre to control) making the LED illumination of door 25 side of first front opening add lustre to gradually, and certain ON time of Figure 24 or OFF time are measured, so can not measure from the ON1 time in order to the LED illumination of reveal opened afterwards.

So, at setting-up time T1 during time Ts to time Te, if open the moment of door afterwards early than T1, the LED illumination of reveal opened then and the LED illumination of the reveal of first front opening are synchronously lighted gradually, on the other hand, if the moment of opening door is afterwards later than T1, after the adding lustre to of the LED illumination of the reveal opened after then making it controls to wait until that the LED illumination of the reveal of first front opening is always ON, after timer 131 terminates the control that adds lustre to of the LED illumination of the reveal of first front opening, use at once timer 131 carry out after the control that adds lustre to of the LED illumination of reveal of opening.

Further citing is described, first, when door after the time Tb moment more Zao than the time T1 moment opens, the LED illumination of the reveal opened afterwards, as shown in the solid line of the figure B of Figure 25, controls at Tb timing synchronization with the adding lustre to of LED illumination of the reveal of the first front opening shown in figure A.Like this, as shown in figure B, in the time Tb moment, the brightness of the LED illumination of the reveal opened afterwards is sharply risen, but textural from freezer, in the time Tb moment, the door opened afterwards itself serves coverage effect, and user cannot see illumination, and, make the sharply ascending amount of brightness can not be excessive by regulation time T1, can prevent from making user have the uncomfortable sensation lighted brightly suddenly.

On the other hand, as shown in the figure C of Figure 25, the time Tc moment during the Te moment from the time T1 moment to the time open after door, if the brightness of the LED illumination of the reveal opened after making it at once with the brilliant synchrotron of the LED illumination of the reveal of first front opening, user then can be made to have the uncomfortable sensation lighted brightly suddenly, so before time (=control not re-use time of timer 131 the adding lustre to of LED illumination of the reveal of the first front opening) Te that controls to terminate of adding lustre to of the LED illumination of the reveal of first front opening, the LED illumination of the reveal opened after making it add lustre to control standby, afterwards use operable timer 131 start after the LED illumination of reveal opened to add lustre to control.

Now, with the time (Te-Tc) accordingly, the starting of controlling of adding lustre to of the LED illumination of the reveal opened afterwards is delayed by, so may make the somewhat bright uncomfortable sensation be delayed by of user.In order to avoid the generation of this situation, in common LED adds lustre to and controls, after opening door, arrange the stand-by period starts controls that adds lustre to again, becomes the action same with time usual thus, so can eliminate uncomfortable sensation that delay lights.

For this reason, such as the process shown in Figure 26 can be implemented.Figure 26 represents to separate the chart that certain hour lights the example of LED illumination gradually after opening door.Illustrate in greater detail, after the time Td moment opens door, after the time through (Ts-Td), start the control that adds lustre to of LED illumination in the time Ts moment, light completely at time Te.Thus, when usual and under the condition of the figure C of Figure 25, also can separate certain interval behind the door and light LED illumination again opening, user can not be made to have postpone the uncomfortable sensation lighted.
