1. Field of the Invention
The present invention relates to a decorative light, and more particularly to an easily assembled decorative lighting string which allows easy connection and can create different flashing effects.
2. Description of the Prior Art
A decorative lighting string is usually installed on trees, in rooms or entertainment places for enhancing the festival atmosphere. A conventional decorative lighting string usually comprises a wire, one end of the wire is formed with a plug for connecting with the power source, and several branch lines having decorative lights thereof are parallel connected to the wire. An early decorative lighting string has no flash function, and its brightness is unchangeable, which is monotonous. Thereby an improved decorative lighting string is developed, which can flash. However, the branch lines are fixed to the wire, after assembly, the decorative lights cannot be replaced, therefore, the shape of the decorative light string is monotonous furthermore, the color of the lights is also monotonous.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a decorative lighting string which can change the flashing effects.
The decorative lighting string is comprises a connector, a rectifier, an housing, a LED lamp and a PCB circuit board. The PCB circuit board is defined with an IC controlling circuit that is provided for controlling the flashing frequency and brightness of the LED lamp, and the rectifier is disposed with a rectifying circuit, and the input and the output end of the rectifying circuit are connected with the input end of the connector and the IC controlling circuit via a wire respectively, and the LED lamp is connected with the output end of the IC controlling circuit, and the LED lamp and the PCB circuit board are defined in the housing.
The above-mentioned housing is cylinder-shaped and candle-shaped.
The above-mentioned input end is a device for direct current and alternating current.
The IC wafers are provided for controlling the glittering frequency and brightness of the LED lamp and connecting the different colors of LED lamps with each other so as to form multi-color lamps, and the connector is connected with an ordinary decorative lighting string directly or connected with the direct current via the rectifier for supplying power. Therefore, this invention is secure and easily assembling.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiments in accordance with the present invention.
Referring to
The PCB circuit board 7 is defined with an IC controlling circuit that is provided for controlling the flashing frequency and brightness of the LED lamp 6. The rectifier 2 is disposed with a rectifying circuit, the input and the output ends of the rectifying circuit are connected to the input end of the connector 1 and the IC controlling circuit via a wire 3 respectively, and the LED lamp 6 is connected to the output end of the IC controlling circuit as shown in
The above-mentioned cylinder-shaped housing 4 as shown in
The said housing 4 can be candle-shaped as shown in
The said IC controlling circuit, the flashing effects of the LED lamp 6 can be changeable by using different kinds of wafers. For example, using the wafer of type S1888, the LED lamp 6 will be flashed changeably, and using the wafer of type S1666, the brightness of the LED lamp 6 can be controlled, and using the wafer of type S1999, the LED lamp 6 will be flashed one by one orderly in turns.
Referring to
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
