Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing the configuration of the LED lamp with a built-in timer function according to an embodiment of the present invention. LED lighting according to an embodiment of the present invention is a power supply unit 10 that receives power from the outside, wired / wireless switches (12, 14) for switching the LED light and select various functions, and the power supply 10 It consists of several LED 22 which is a semiconductor element which light-emits by the power supply supplied from ().

In particular, the present invention is a timer unit 20 for controlling the lighting brightness of the LED 22 in a multi-step inside of the LED lamp including a circuit board in which a plurality of LED 22 is regularly installed as described above, and in case of power failure And a battery unit 16 used as an auxiliary power source and a controller unit 18 which variably controls the lighting brightness of the LED in association with the timer unit 20.

Referring to FIG. 2, the power supply unit 10 configures a circuit in which a general AC current is input, receives AC power through an AC power input terminal, and drops a voltage to supply power to an LED lamp. The wired switch 12 is a switch installed in a main body of an LED lamp to turn on / off a plurality of LEDs 22 and also includes a power switch for switching power supplied from the outside. In this case, the wired switch 12 may apply a touch method. When the power switch is applied to the LED lamp, the wireless switch 14 performs wireless communication between the remote controller and the LED lamp through a bidirectional transmission and reception module to turn on / off the plurality of LEDs 22 as well as to switch power supplied from the outside. to be. The wire / wireless switches 12 and 14 have functions to turn on / off the power or to perform dimming (brightness control) up / down, sleep mode, wake-up mode, timer setting, and initialization of the LED 22. It is included.

On the other hand, the timer unit 20, which is one of the main components of the present invention is a configuration for adjusting the lighting brightness of the LED lamp step by step when performing the sleep mode function and the wake mode function, specifically, when the sleep mode function The lighting brightness of the LED 22 is gradually darkened over time, and in the wake-up mode function, the lighting time of the LED lamp is set to gradually brighten the lighting brightness of the LED 22 over time. The detailed operation of the timer unit 20 will be described in detail in the control method of the controller unit 18 to be described later.

In addition, the battery unit 16 of the present invention is an auxiliary power supply means for turning on the LED lamp when the power supplied from the power supply unit 10 is cut off (that is, power failure), preferably rated at the time of power failure Save 50% of the LED lights. In this case, the battery unit 16 may configure a circuit to enable self charging when power is input from the power supply unit 10.

In addition, the controller unit 18 includes a general power control unit and a central processing unit, and controls the on / off of the LED 22 and the signals corresponding to the signals input from the wired / wireless switches 12 and 14. Perform the action. That is, the controller unit 18 controls not only basic operations such as LED lighting, but also interlocks with the timer unit 20 when the sleep mode function and the wake mode function are set by the wire / wireless switches 12 and 14. Controls an operation of gradually adjusting the lighting brightness of the LED 22. Such a control method of the controller unit 18 will be easily understood by FIGS. 3A and 3B described later.

3A and 3B are views illustrating a control method of an LED lamp having a built-in timer function according to an exemplary embodiment of the present invention. In the following description, among the control methods of the LED lighting, a basic control operation, for example, the operation of turning on / off the LED lighting, the dimming (brightness control) up / down operation of the LED, and mounting the LEDs having various colors on a circuit board Note that the operation of selectively turning on / off the LED by the operation of the wire / wireless switch will be omitted.

Referring to FIG. 3A, when power is supplied from the power supply unit 10 or when the power is supplied from the battery 16 at the time of power failure, the controller unit 18 may remove the power from the wire / wireless switches 12 and 14 in step 100. Check that the mode function is switched. If it is determined in step 100 that the mode function is selected by the switching 'on' of the wired / wireless switches 12 and 14, the controller 18 determines whether the sleep mode function is selected in step 102.

If it is determined in step 102 that the sleep mode function is selected, the controller unit 18 determines whether a timer is set in step 104. That is, when the user wants to sleep between the set time input from the timer unit 20, for example, from 10 to 11 o'clock, the start of the sleep mode is set to 10 o'clock and the end is set to 11 o'clock through the timer unit 20. Then, the controller unit 18 decreases the lighting brightness of the LED 22 step by step from 10 o'clock to 11 o'clock. This is explained in detail in the next step below.

When the controller 18 determines that the timer is set in step 104, the controller 18 controls the lighting brightness of the LED 22 to be 100% from the time set in step 106 (eg, 10 o'clock), and sets in step 108. By the time (for example, eleven o'clock), the lighting brightness of the LED 22 is gradually decreased step by step. If it is determined in step 104 that the timer is not set, step 102 is performed.

Thereafter, the controller 18 determines whether the time set in step 110 (for example, the sleep mode function is set from 10 to 11 o'clock) has elapsed. If it is determined that the time set in step 110 has elapsed (for example, 11 o'clock has passed), the controller unit 18 decreases the brightness of the LED 22 to 10% and lights it in step 112. At this time, the LED 22 is turned on while maintaining only 10% of brightness continuously under the final control of the controller unit 18, and eventually the LED lamp performs the function of a sleeping lamp.

If it is determined that the time set in step 110 has not elapsed, the controller unit 18 continuously performs step 108 described above to gradually decrease the lighting brightness of the LED 22.

Meanwhile, if it is determined in step 102 that the sleep mode function is not selected, the controller unit 18 determines whether the wake mode function is selected in step 114 as shown in FIG. 3B. If it is determined in step 114 that the wake-up mode function is selected, the controller unit 18 determines whether a timer is set in step 116. If it is determined in step 114 that the wake-up mode function is not selected, the controller unit 18 performs step 102 described above.

Next, when it is determined in step 116 that the timer is set, the controller unit 18 wakes up to wake up from 6 o'clock to 7 o'clock through the timer unit 20 of FIG. 2. If it is determined that the mode function is set, the LED 22 is turned on at the time set in step 118 (for example, 6 o'clock). At this time, the controller unit 18 turns on the LED 22 at about 10-20% of the overall brightness of the LED lamp.

Thereafter, the controller 18 gradually increases the lighting brightness of the LED 22 step by step until a set time (for example, 7 o'clock), and then determines whether the set time has elapsed in step 122. If it is determined that the time set in step 122 (for example, seven o'clock has passed) has passed, the controller unit 18 increases the brightness of the LED 22 to 100% and turns on the lamp in step 124. At this time, the LED 22 is continuously turned on while maintaining only 100% brightness under the final control of the controller unit 18. If it is determined that the time set in step 122 has not elapsed, the controller 18 continues to increase the lighting brightness of the LED 22 by performing step 120 described above.
