THE ELECTRONIC SWITCH FOR LIGHTING LAMP THAT HAS SECURITY FUNCTION
|Abstract||This is about the method for performing security function of wall mounted use electric switch and the switch itself. The invented product comprising control micom [U1] operates 24 hr clock based on the outside luminance detected by CDS. The switch turns off lamps during daytime and turns on lamps during specific nigh times according to the on/off timer program [s108] loaded in the micom [U1], when the security mode is set on by the users one touch key [SW2] the switch turns on and off lamps according to the users on/off key [SW1] when the security mode is not set. Because users can operate the security function without a clock setting or time schedules it is convenient to use. And, because lamps are turned off during the daytime, power consumption is also reduced.|

THE ELECTRONIC SWITCH FOR LIGHTING LAMP THAT HAS SECURITY FUNCTION;
HAGA ELECTRONICS CO., LTD., A COMPANY ORGANIZED AND EXISTING UNDER THE LAWS OF REPUBLIC OF KOREA, WHOSE ADDRESS IS 11F, CHEONROK BLDG., 1351-3, SHINGIL-DONG, YOUNGDEUNGPO-GU, SEOUL 150-057, REPUBLIC OF KOREA.
THE FOLLOWING SPECIFICATION
PARTICULARLY DESCRIBES THE
NATURE OF THIS INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.
The invention introduction is "the method of performing the security Function of the Switch and the Switch itself [hereinafter/The Switch"]. The Switch can substitute the existing mechanic switch, of which the sole function is to turn on and off Lamps, and has a one-touch security Function. Normally, night thieves watch for houses where lamps are turned off. Therefore, turning lamps on in the early evening can prevent thieves. When leaving home for a long time or when you expect to come home late, use the security Function.
As shown by , if you turn the Switch on for 24 hours, it needs much electric power, and thieves may look for houses where Lamps are turned on 24 hours a day. If using The Switch equipped with clock functions to turn on Lamps at scheduled times only, it is necessary to adjust time and schedules again after power failures.
Apparatuses and methods for controlling the lamp turn On and turn Off based on the ambient light intensity are disclosed in the state of the art International patent application n. W09627823, describes a method for controlling a switch on the basis of prevailing light intensity so that the switch is turned on when the light intensity falls below a set threshold value and it is turned off when the light intensity exceeds the set threshold value. The method is implemented as
follows: when a stable change in the prevailing light intensity is detected, this is interpreted as being morning or evening, then from these moments sunrise and sunset times may be calculated and a clock is synchronized according to them thus, achieving the daily timing of the switch and the consequent control of the switching of the load.
The present invention introduces an improvement of the above solution providing a simple method for controlling the switching On and Off of a lamp according to the ambient light intensity.
Disclosure of Invention
With the help of this invention, "users of the Switch" (hereinafter, "Users") can
easily operate "the security Function of The Switch" using the one-touch
Another purpose of this invention is to provide "The Switch" which has normal
on-off functions and security Function.
The features of The Switch are that, if the security Function is set on, the
security Function status is shown by its LED lamp and with the luminance
sensor [CDS] distinguishes day time and night time. It turns lamps off during
day time and turns Lamps on for four or five hours in the evening after sunset
and turns them on again in the early morning before sunset only, for one or two
hours. The product has an on-off key to turn Lamps on or off, a security
Function key, a LED lamp and a light sensor to distinguish night and day, and to operate a 24 hour clock in itself.
Therefore, users can easily turn the Lamps on or off, and set security status using its one touch function.
Refer to attached drawings for detailed practical and desirable usages. shows a normal wall Switch, and is the circuit configuration of the Switch adopting this invention. Terminal (D and (2) in link switch lines on walls. Drawing mark 1 is the driving power circuit block of the Switch, and Drawing mark 2 is a circuit block to detect the phase of AC input. Drawing mark 3 is Triac[TRC] and its driving circuit block to switch Lamps, and Drawing mark 4 is a control Micom and its surround circuit block, which controls the operation of the Switch. The terminal Ol and 02 of Micom are output terminals, andM - 14 are input terminals. When No. 1 output  is Logic 1 [High], Triac[TRC] is turned On to turn on Lamp, and when No. 1 output is LogicO [Low], Triac[TRC] is turned Off to turn off Lamp. The fourth input terminal[l4] of Micom[U1] is an analog input terminal to detect luminance, and No.1 and No. 2 input terminals[11-12] are Key input terminals. If No. 2 output is high, LED turns on and the Security Mode is set. And No. 2 output[021 is low, LED turns off and the security mode is changed to normal mode. Pushing SW2 makes the setting status change. Under Normal Mode, SW1 is
used to turn the Lamp on or off, and, Micom[U1] detects luminance to operate its 24 hr clock, and controls the Lamp using its on-off timer program. Micom[U1] sets A. M. 12: 00 as a central point between dawn and early evening, and sets P. M. 12: 00 as a central point between early evening and dawn to operate the 24 hr clock. Under Security Mode, the Lamp is on for four or five hours during the evening, once or twice for brief times around midnight, and for one or two hours during the early morning. is the Flow Chart of the Switch showing the method for performing the unique security function of this invention.
When a key is inputted [S101], whether the key is security key or not is determined [S102]. If it is not the Security Mode key, then appropriate orders are performed. If it is Security Mode key, Mode is changed from Security to Normal or Normal to Security[S103], and then changed status is shown[S104], If the status is Normal Mode, then waiting for another key input, regarding given orders have been completely performed. If the changed status is Security Mode, Micom determines whether it is day or night using the 24 hr clock[S106]. If it is daytime, it turns the Lamps off [S107], and checks Security or Normal Modes[S105]. If it is nighttime, the Lamp is controlled by the On/off Timer Program in U1[S108], and Security or Normal Modes are checked[S105]. (1) shows that Micom [Ul] detects luminance using CDS to determine whether it is day or night, and (2) shows output Timing
Drawing when adopted this security Function. shows one of the exterior view of the Switch.
As described above, using the Switch, Users can easily operate the security Function using the one touch button. The function is operated by the 24 hr clock, made by determing daytime and night time using luminance sensor and the On-Off Timer Program in U1. Because, the Switch itself determines when to turn the Lamps on or off automatically and turn the lamps off in day time this invention gives energy saving effect and convenience to the user of the switch.
