Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a lighting and flashing Christmas tree structure apparatus, in particular, to a lighting and flashing Christmas tree structure apparatus that features a plug-free electrical power system with multiple power receptacles to supply LED drive currents, a low power control circuit to control the flashing sequence of LED light strings and randomly altering distribution of the light strings with free choice of colors. 
   2. Description of the Prior Art 
   The most popularly seen and preferred types of traditional Christmas trees are mostly a composition of integral parts of a tree trunk. To beautify an overall Christmas tree complex, a variety of ornaments are usually hung and Christmas lamps are wound around the trunks, followed by a power line connected to each lamp to illuminate the lamp, thus making the tree gorgeous and decorating the holiday with joy. 
   The Christmas trees mentioned in the foregoing are enriched with gorgeousness and the joys of the Christmas holiday by the shining of the lamps, but there are some defects in the actual usage:
         1. The traditional Christmas trees have Christmas decorative lighting by tiny glass bulbs which are not the economical way of lighting and consume higher power that causes contamination, labors, hazardousness and being costly.   2. The traditional Christmas trees demand 3-wire power plug and extra efforts for installing decorative lighting that results in safety concerns.   3. The add-on process for the manufacture of the traditional Christmas lamps is not available for automatic testing, and the assembly is also tedious, limiting the production rate and raising the costs.   4. The method of manufacturing the traditional Christmas trees is not only costly, lengthy, and low in product yield rate, but quality assurance and production requirements fail to meet total quality control, which deteriorate safety and cost control.   5. The whole light string in the traditional Christmas trees goes down only if one fails which is very annoying.       

   SUMMARY OF THE INVENTION 
   It is an object of the present invention to offer an innovative lighting and flashing Christmas tree structure apparatus that features multiple power receptacles, the control of a flashing sequence of LED light strings by means of a low power control circuit, randomly altering the distribution of light strings with free choice of colors, and provision of magnetic contacts and free selection of a preferred power receptacle. 
   Another object of the invention is to replace power plugs with the magnetic contacts for electrical conduction, simplifying production assembly to spare resources. 
   A further object of the invention is to provide a mode of inputting electrical power by diminishing windings of lamp strands with the magnetic contacts, and through the simple mode of electricity supplying to simplify the prior production approach, which will substantially help in cutting down labor costs. 
   A still further object of the invention is to use the magnetic contacts to connect to the LEDs and to append a limiting resistor to it. The value of the limiting resistor is dependent on the number of LEDs in series, which is used for limiting unexpected surges in electrical power from burning the LEDs. The process of manufacturing the magnetic contact is plain and testing for add-on process is easy. The magnetic contact is electricity economizing so that there is no overload in the circuit which ensures the safety in operating and longer life in use. 
   A still further object of the invention is to provide a low power connection by the magnetic contact where the low power is 24Vac or 24Vdc signal voltage which is within the safety range of the electrical properties code for body contact; therefore, wavering the UL safety certification and CE safety and EMC approvals, which tremendously shortens the shipment and strengthens product competition. 
   A still further object of the invention is to offer users required lighting colors for performing DIY in the design of Christmas tree lighting, free of electric shock and safety concerns, and easy for replacement by replacing the malfunction part only. 
   The lighting and flashing Christmas tree structure apparatus having the foregoing advantages according to the present invention comprises: 
   A conductive tube, which is a body, has multiple orifices, where the body may take different shapes having cross section as a rectangle, a circle, or a trapezoid;
