1. Field of the Invention
The present invention relates to a serial lamp set having security warning functions, especially to a serial lamp set formed by a serial lamp set unit or a plurality of serial lamp set units. If the load of a serial lamp set unit is over the preset limitation value of an electric property, a preset security warning signal shall be released.
2. Description of the Prior Art
The conventional light emitting apparatus are basically composed of light emitting elements such as lamps, LEDs to connect electric conducting wires with power source and develop the functions of illumination or decoration. Generally, the light emitting apparatus is formed by connecting a plurality of light emitting elements in series or in parallel or in series-parallel as a serial lamp, after the power source is connected and the current flows into the light emitting apparatus, variable kinds of flash lights are then generated as a decoration in celebration, business advertisement and other special fields.
However, the number of light emitting elements of said conventional serial lamp set shall be affected by the articles used for hanging the serial lamp set by people. For example, the Christmas trees may be as high as several tens meters to several tens floors. It is not only lightened for a long time, when the light emitting elements of light emitting apparatus formed by a plurality of serial connected lamps are lightened simultaneously, the loads of electric wires are very high. And, the temperature increasing occurred due to longtime lightening of Christmas lamps always accidentally cause the burning of Christmas trees and the fires. Consequently, a thermo-alarm for Christmas tree is then created in order to prevent the accidents. It is a unique article to be hanged onto Christmas tree alone, and mainly includes a thermo sensor for detecting abnormal temperature vibrations, signals happened around it, and amplify the signal by an amplifier, then trigger an audio circuit to generate visible or audible signals. However, because its electric power is generated by the battery installed inside it, when the electric power is not sufficient for operating electric circuit or the user forgets to change new batteries, its functions of warning will be lost, and the accidents still may be occurred.
Besides, said method of detecting the temperature outside Christmas tree and then releasing alarm signals not only will decrease the accuracy of sensor due to environmental conditions, but also may not generate visible or audible signals when the load of electric wire is over a pre-determined value. This is also a disadvantage of conventional apparatus.
Accordingly, the primary object of the present invention is to provide a serial lamp set having security warning functions, when the current load of the power source connected by the power source connector is over the preset limitation value of an electric property, a preset security signal will be emitted.
According to the a serial lamp set having security warning functions of present invention, the construction for detecting whether the load of serial lamp set is over the preset limitation of an electric property contains an integrated circuit (IC) set installed in the electric connector of power source, said integrated circuit (IC) set has the functions of receiving the signal of electric power, generating pre-set functions, presetting limitation values of electric properties, emitting signals and pre-setting security warning functions, so as to provide basic protection to the serial lamp set.
According to the serial lamp set having security warning functions of present invention, it further provides a plurality of serial lamp set units connected in series, or in parallels or in parallel-series, each of the serial lamp set unit is composed by a plurality of light emitting elements, insulated electric wires, power source receiver and power supply; and a plurality of integrated circuit (IC) sets to be connected in said serial lamp set units, it has the functions of receiving the signal of electric power, generating pre-set functions, presetting limitation values of electric properties, emitting signals and pre-setting security warning functions; by connecting the serial lamp set units with power source, the integrated circuit (IC) sets would receive the total electric properties of said numerous serial lamp set units, and when the total electric properties of said serial lamp set is over the pre-limited value, a warning signal will be released and the signal will be transmitted to each serial lamp set unit and then an alarm signal will be emitted simultaneously by each serial lamp set unit.
