[Prior art]

  Tree lights are a dazzling decoration, originally used for Christmas tree decorations Eventually, it was used to decorate buildings, street trees and gardens, now at night. It is a regular ornament to enhance the atmosphere of the room. Currently considering power saving and waterproofing Considering that, most of the tree lights are originally color bulbs connected in series. Instead of using seed color light emitting diodes (LEDs). But from There are various colors of photo diodes, but if the color of the light emitting diode is different, The voltage is different, for example, the voltage applied to the white light emitting diode is 4V. , The voltage applied to the red light emitting diode is 2V, the tree of different colors The light branch lines have different voltages, which is why the light of one treelight branch line The stream is dark and the luster of another treelight branch is relatively bright. Relatively dark color In order to prevent the light emitting diode of the A current value within the permissible range of Has a short life and is easily burned. Such a known structure is shown in FIG. At the back of the power plug 91, there is a control box 70 and a current limiting resistor 80. , And a plurality of LED lamps 90 are provided. Among them, the control box The box 70 is provided to control the blinking or blinking method of the LED lamp 90. However, since there is no rectification function in the whole series lamp, after being connected to the AC power source, When the pressure is unstable, the LED lamp 90 is easily damaged, and one LED lamp 90 It is inconvenient to replace the entire tree lamp, which makes it unusable and wasteful. To achieve. The above are the main drawbacks of the known structure.

[Problems to be solved by the device]

  Therefore, the present invention solves the above-mentioned problems, particularly by using a rectifier diode as a resistor. Connect in series in front of the resistor, and use plastic for navigation to connect the rectifier diode and resistor outside. Sealing, achieving waterproof effect, rectification, pressure regulation, and limiting excessive current flow And protect the tree light in a timely manner to extend its life, which The drawbacks of the prior art are solved.

[0004]

[Means for Solving the Problems]

  In the invention of claim 1, a power plug is provided at one end of the power line, and a plurality of power plugs are provided on the power line. LED lamps connected in series and connected to the power line in series In a tree light with a resistance in front of,   A rectifying diode is further provided in front of the resistor, and the resistor and the rectifying die are provided. The odes are connected in series as well as enclosed in a plastic hard case for rectification Part is formed, and when the AC power supply passes through the rectification part, it is rectified and decompressed, and stable current Is supplied to the LED lamp and is designed to extend the life of the tree light. Tree light, featuring   According to a second aspect of the present invention, in the tree light according to the first aspect, a light source is provided on a power line. It is a tree light with a control box provided. .

[0005]

[Embodiment of device]

  According to the present invention, a power plug is provided at one end of the power line, and a plurality of LED lines are provided on the power line. Lamps are connected in series and in front of the LED lamps connected in series on the power line. In a tree light provided with a resistor, a rectifying diode is further provided in front of the resistor. Is provided, and the resistor and the rectifier diode are connected in series, and Enclosed in a tic hard case to form a rectifier, and AC power passes through the rectifier When rectifying, the voltage is adjusted to the proper voltage by the resistor, Introduced into ode series lamp, stable current and voltage flow through the whole tree lamp , The life of the rectifier is a plastic case. Since it is completely sealed, it is characterized by having a waterproof effect.

[0006]   The present invention is also equipped with a control box in front of the rectification part of the power line, Flashes in various ways, which is another embodiment of the present invention. There is.
