Description

LUMINAIRE A LIGHTING CONTROL UNIT

  MULTIPLE PROGRAMMING AND EASY INSTALLATION.

BACKGROUND OF THE INVENTION

  This invention relates to a switch embodying an ON / OFF / on / off programming device for luminaires. This easy-to-install multiple-programming lighting control unit consists of a cover subassembly, a base subassembly, and an electronic subassembly. The electronic sub-assembly, which contains two components forming a printed circuit board (hereinafter referred to as PCBA) in and between the cover sub-assembly and the base sub-assembly, performs the function of programming the information and triggering the relay for ON / OFF / lighting on / off control. A commonly used commercial contactor can be mounted on this switch. Due to the design and structure of this switch, the installation of this switch will not conflict with any other conventional switch. With this design, a user can program their own programming to turn on or

  automatically turn off lights at a designated time.

  Over the past twenty years there has been rapid progress in the development of electronic devices. It is becoming more and more apparent that a multifunctional product constitutes the new development trend. The conventional control unit for lighting lights has many drawbacks such as (1) it has to be operated by hand; (2) it does not have the function of programming an ignition / extinction sequence; (3) it interferes by nature with certain light devices; (4) there are problems of comparability with certain switches

existing fixtures.

SUMMARY OF THE INVENTION

  Consequently, the first object of the present invention is to propose a multifunctional member for controlling the lighting of lights to make possible a switch of lights with automatic control and easy to use. The present invention, a control member for the lighting of multi-programming luminaires and easy installation, uses a relay as a basic element for its operation. In general, a reference time is programmed on the ignition control member. When the time corresponds to the reference time, the relay trips and forces the switch to turn on or off. In addition, the relay of the present invention uses a commercial contact with bars in common use. There will be no phenomenon of non-comparability. It can be concluded that the object of the present invention is to provide an easy and flexible programming device lighting control member, based on user programs.

  DETAILED DESCRIPTION OF THE EMBODIMENTS

PREFERRED

  Referring to FIGS. 1 and 2, the embodiments of the control member for the ignition of multiple-programming and easy-to-install luminaires 1 of the present invention consist of a subassembly forming a cover, d '' a subset forming the base and

an electronic sub-assembly.

  The cover subassembly 10 mainly consists of a liquid crystal display (LCD) 11, function buttons 12, a circular cover 13, battery compartments 14 and a front panel 15. The programming information will be prescribed by the function buttons 12 and displayed on the LCD / 11 display. The front panel

  U-shaped is designed for easy installation of batteries. The sub-

  base assembly 20 has a reserved place 21 prepared for placing the electronic sub-assembly therein, as well as four holes for the combination of the cover sub-assembly 10 and the base sub-assembly 20 by means of screws. The electronic sub-assembly 30 consists of two components forming a printed circuit board PCBA_B / 31 and PCBAB / 32 which are placed between the sub-assembly forming the cover 10 and the sub-assembly forming the base 20. The component PCBA_A / 31 makes d an integrated circuit is a main control circuit. Via links with the function buttons, the component PCBA_A / 31 transmits information to be read to the LCD display. The component PCBAB / 32 consists of a relay, a neon lamp and transistors. The relay comprises a pair of strip contacts 33 for the connection with the power source. Two batteries can be housed in the battery compartments 14 to supply the energy required for the relay and for the PCBA components. According to the structure described above, the installation procedure for this switch includes the sequence 1. connect the bar contacts 33 2. screw the base sub-assembly 3. install the electronic sub-assembly 4. place the cover subassembly to form a device ready to program the program by pressing the

function buttons.

  Here is a brief user guide on how to

  program this lighting control unit.

  Press "PROG" (the first button from the left).

  This will take you to the first programming step for ON / OFF / on / off. For example, press "PROG" to display "1 ON / on -: -". Press "PROG" again to display "1 / OFF / off -: -"; And so on. There will be eight program steps

  different by successively pressing "PROG".

  Press "DAY / day" to display the day of the week. through

  example Mo / Lu, Tu / Ma, We / Me, Su / Di ".

  Press "HOUR / hour" to prescribe the hour.

  Press "MIN" to prescribe the minute.

  Press "CLOCK" to display the current time.

  Press "RESET / reset" to erase all the information,

including the time.

  Press "MANUAL / manuel" to allow you to switch off

  or switch on despite the programming.

  It can be seen that the design of this invention is built on an on / off relay and an electronic circuit. The on / off status of a luminaire can be automatically obtained at a designated minute by prescribing the day / time information by means of the function buttons, based on a user program. The other important point concerning this invention is that this device consumes a small amount of energy only when the bar contact trips. Most of the time the relay is not in action and the only energy consumption is caused by the LCD display and the integrated circuit which consumes less energy compared to that required to trip a relay. It is clear that this device has the advantage of low energy consumption. The neon lamp located under the circular cover lights up as a night light each time the switch has the OFF / OFF status. The purpose of the pilot is to guide the location of this switch in the dark. In addition, the circular cover is designed to be an independent on / off switch so that maneuvering the circular cover will not conflict with

  the previous programming step.

  It can be concluded that the relays and the on / off status of a luminaire activated by the user's own programming play an important role in this request. In addition, the illuminated neon lamp indicates that the relay has moved to the ON / on position. In addition, many different types of luminaires can be applied to this switch, since it is capable of avoiding interference. Some other important points are that the bar contacts used by this switch have the same structure as other commercial bar contacts and that two batteries serve as a power source. This exclusive design

  makes this switch a device without comparability.
