1. Field of the Invention
The present invention relates to a light apparatus, and more particularly to a Christmas light apparatus and a lamp base thereof.

Each pin 71 of the LED lamp has its own function. If a wire is welded to a wrong pin 71, the LED lamp will be incorrectly activated with a wrong luminance color or will not be activated at all. In addition, since the wires are welded to the pins 71, the wires are not securely connected to the pins 71 and are easily disconnected from the pins 71. Hence, if the Christmas light apparatus is frequently hanged on and taken off a Christmas tree, the wires will be disconnected from the pins 71. The Christmas light apparatus is then out of order.
An objective of the invention is to provide a Christmas light apparatus and a lamp base of the Christmas light apparatus to overcome the disadvantage that the wires are easily disconnected from the pins of the conventional Christmas light apparatus.
The Christmas light apparatus of the invention has:
a holder having an inner surface and a space;
multiple electrode pads mounted on the inner surface of the holder;
a lamp base mounted in the space of the holder and having:
an LED lamp mounted on the top body of the lamp base and having multiple pins each respectively having a free end, wherein the free ends of the pins pass through the lamp base and are respectively bent upward along the bottom grooves of the bottom body to be respectively pressed between the lamp base and the electrode pads.
The lamp base of the invention has:
a top body having a top hole; and
a bottom body extending from a bottom of the top body and having multiple bottom grooves communicating with the top hole of the top body.
In conclusion, the pins of the LED lamp pass through the lamp base, extend from the bottom of the lamp base and are bent upward to be respectively pressed between the four surfaces of the lamp base and the electrode pads. The pins are then in close contact with the electrode pads. Hence, the LED lamp is securely mounted on the lamp base, and the pins of the LED lamp closely contact the electrode pads. The pins of the LED lamp can hardly be disconnected from the electrode pads, such that the Christmas light apparatus of the invention can be always normally activated.
In addition, an assembly worker mounts the LED lamp on the lamp base, bends the pins of the LED lamp upward and inserts the lamp base to the holder to complete assembly of the Christmas light apparatus of the invention, instead of welding wires to the pins of the LED lamp. Therefore, to assemble the Christmas light apparatus of the invention is easy and fast.

The holder 10 has an inner surface and a space 11. The space 11 has a top opening. The inner surface has multiple pad recesses 13.
The multiple electrode pads 12 are respectively mounted in the pad recesses 13. In this embodiment, the inner surface of the holder 10 has four pad recesses 13. Four electrode pads 12 are respectively mounted in the four pad recesses 13.
The lamp base 20 is mounted in the space 11 of the holder 10. The lamp base 20 has a top body 21 and a bottom body 22. The top body 21 has a top hole. The top hole of the top body 21 is partitioned into a first space 211 and a second space 212. In this embodiment, the top body 21 has a partition 213. The top hole of the top body 21 is partitioned by the partition 213 into the first space 211 and the second space 212.
The bottom body 22 extends from a bottom of the top body 21 and has a first surface 221, a second surface 222, a third surface 223, a fourth surface 224, at least one bottom hole and multiple bottom grooves. In this embodiment, the bottom body 22 has a first bottom hole 225, a second bottom hole 226, a first bottom groove 231, a second bottom groove 232, a third bottom groove 233 and a fourth bottom groove 234. The four surfaces 221-224 respectively face toward the electrode pads 12 mounted on the inner surface of the holder 10. The four bottom grooves 231-234 are formed in a bottom of the bottom body 22. The first bottom hole 225 communicates with the first space 211 of the top body 21, the first bottom groove 231 and the second bottom groove 232. The second bottom hole 226 communicates with the second space 212 of the top body 21, the third bottom groove 233 and the fourth bottom groove 234. The positions of the bottom grooves 231-234 respectively correspond to the positions of the surfaces 221-224 of the bottom body 22.
The LED lamp 30 is mounted on the top body 21 of the lamp base 20 and has multiple pins including a first pin 31, a second pin 32, a third pin 33 and a fourth pin 34. The four pins 31-34 each respectively have a free end passing through the lamp base 20. In this embodiment, the free ends of the first pin 31 and the second pin 32 pass through the first space 211 and the first bottom hole 225. The free ends of the third pin 33 and the fourth pin 34 pass through the second space 212 and the second bottom hole 226. The free ends of the four pins 31-34 are respectively bent upward along the four bottom grooves 231-234 and are respectively and tightly pressed between the surfaces 221-224 and the electrode pads 12, such that the free ends of the pins 31-34 are respectively and electrically connected to the electrode pads 12 and the pins 31-34 are electrically insulated from each other. When the LED lamp 30 is activated, the LED lamp 30 can display multiple colors.
The cover 40 is mounted on the top body 21 of the lamp base 20 to cover and protect the LED lamp 30.

Hence, before an assembly worker assembles the lamp base 20 to the holder 10, the assembly worker has to align the first pillar unit 251 with the first hole 111 of the holder 10, align the second pillar unit 252 with the second hole 112 of the holder 10, and align the protrusion 14 with the fool-proofing notch 26, such that the assembly worker can correctly insert the lamp base 20 in the holder 10. In addition, the pins 31-34 can contact the right pads 12, such that incorrect assembly of the LED lamp 30 is prevented. The assembly worker can also observe the length of the pins 31-34 on the surfaces 221-224 to determine whether the LED lamp 30 is correctly mounted on the lamp base 20.
When the first pillar unit 251 is incorrectly inserted in the second hole 112 and the second pillar unit 252 is incorrectly inserted in the first hole 111, the lamp base 20 cannot be completely mounted in the holder 10, such that the assembly worker can easily observe the lamp base 20 is not aligned with the holder 10.
With reference to
In conclusion, the LED lamp 30 is detachably mounted on the lamp base 20 and the lamp base 20 is detachably mounted in the holder 10, such that the pins 31-34 of the LED lamp 30 can correctly contact the electrode pads 12. The assembly worker can easily assemble the light apparatus of the invention. The pins 31-34 of the LED lamp 30 are tightly pressed between the bottom body 22 and the electrode pads 12 and can hardly be disconnected from the electrode pads 12. The disadvantage that the pins of a conventional LED lamp are easily disconnected from wires melded to the pins is overcome.
