Abstract

A serial lamp set having security warning functions comprising at least one serial lamp set unit composed of a plurality of light emitting elements, insulated electric wires, and power source connector; at least one IC set being connected in the serial lamp set for receiving the signal of electric power, generating pre-determined functions, having set limitation values of electric properties of the serial lamp set, emitting signals, such as a warning signal, and having set security warning functions. After the power connector is connected to the power source, a preset security warning signal shall be released at the time when the load of the serial lamp set is over the preset limitation value of an electric property.

Claims

1. A serial lamp set having security warning functions comprising:

a plurality of serial lamp set units connected in series, or in parallel, or in parallel-series, each serial lamp set unit including a plurality of light emitting elements, insulated electric wires, a power source receiver having a signal generator and a power supply having a signal sensor; and

a plurality of integrated circuit (IC) sets, at least one IC set being connected to said serial lamp set unit, said plurality of serial lamp units being connected to a power source, each said IC set receiving an electric power signal, each said IC set having set limitation values of electric properties and having set security warning functions, said plurality of IC sets receiving the total load of said plurality of serial lamp set units, each IC set emitting a warning signal when the total load of said plurality of serial lamp sets exceeds one of said electric property limitation values, said warning signal being transmitted to the signal sensor of said power supply, whereby an alarm signal is emitted by each serial lamp set unit simultaneously.

2. The serial lamp set having security warning functions as claimed in claim 1, wherein said light emitting elements are light bubbles, or LED lamps.

3. The serial lamp set having security warning functions as claimed in claim 1, wherein said light emitting elements are installed onto kinds of sockets or lamp seats.

4. The serial lamp set having security warning functions as claimed in claim 1, wherein one end of said power source connector is a power supply, the other end is a power source receiver.

5. The serial lamp set having security warning functions as claimed in claim 1, wherein said signal displayer is a LED lamp, said LED lamp turning red to indicate an unsafe condition.

6. The serial lamp set having security warning functions as claimed in claim 1, wherein said power source forms together with said IC set without connection of insulated electric wire.

7. The serial lamp set having security warning functions as claimed in claim 1, wherein said IC set composes a plurality of IC chips, resistors, capacitors, diodes, connection terminals, pc board and insulated housing.

8. The serial lamp set having security warning functions as claimed in claim 1, wherein the warning functions of said IC set is displayed on its insulated housing.

9. The serial lamp set having security warning functions as claimed in claim 1, wherein said warning functions are displayed by LED lamp having a red light and a green light, said green light indicating a safe condition, said red light indicating an unsafe condition.

10. The serial lamp set having security warning functions as claimed in claim 1, wherein said signal sensor is connected with said IC set by insulated electric wire to receive and detect the condition of power receiving end, said condition of said power receiving end being displayed on the housing of said IC set.

11. The serial lamp set having security warning functions as claimed in claim 1, wherein said signal sensor is a CDS photo-sensitive resistor.

12. The serial lamp set having security warning functions as claimed in claim 1, wherein said signal is installed inside the power supply to prevent outside interference.

13. The serial lamp set having security warning functions as claimed in claim 1, wherein after said power supply is connected with power source receiver, the signal sensor installed at power supply matches with signal generator correspondingly.

14. The serial lamp set having security warning functions as claimed in claim 1, wherein after the numerous sets of power supply and power receiver are formed, when the first serial lamp set unit having security warning functions connects to power source, its IC set then detects the load of total electric properties, and compare the load with the preset limitation value of electric properties, so as to display its security conditions.

15. The serial lamp set having security warning functions as claimed in claim 14, wherein the detect conditions from the first serial lamp unit having security warning functions is then transmitted to the serial lamp unit having security warning functions connected at the rear end of said first serial lamp unit, and all of the warning functions are in operation, the security of numerous serial lamp sets are then confirmed.

16. A serial lamp set having security warning functions, comprising:

a plurality of serial lamp set units connected in series, or in parallel, or in parallel-series, each serial lamp unit having a plurality of light emitting elements, insulated electric wires, a power source receiver having a signal generator and a power supply having a signal sensor; and

a plurality of integrated circuit (IC) sets, at least one IC set being connected to said serial lamp set unit, said plurality of serial lamp set units being connected to a power source, each of IC set receiving an electric power signal, each IC set having set electric property limitation values and having set security warning functions, said IC sets receiving the total electric properties of said plurality of serial lamp set units, each IC set emitting a warning signal when the total electric properties of said plurality of serial lamp sets exceeds one of said electric property limitation values, said warning signal being transmitted to said signal sensor of said power supply.
