Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, in particular to an LED lamp for a Christmas tree. Background Art

[0002] In some countries or regions, when Christmas comes, people usually put a Christmas tree at home, and then hang LED lights, Christmas balls and other decorations on the Christmas tree. The LED lights used on existing Christmas trees are usually divided into DIP (plug-in lights) and SMD (surface mount lights).

[0003] At present, DIP lamps can be directly connected and used (such as string lights on Christmas trees), while SMD lamps need to be soldered on PCB circuit boards to work. For example, the luminous range of DIP lamps is about 120-160 degrees when the LED lamp feet are downward. SMD lamps usually irradiate upwards because they need to be soldered on circuit boards, so the irradiation range is usually only 120-180 degrees. Therefore, when these LED lamps are installed on Christmas trees, the luminous body is usually set outward so that the light can be seen. If the luminous body is inward, it can only illuminate the inside of the Christmas tree without any luminous effect. However, because the luminous body is outward, the leaves of the Christmas tree cannot be illuminated (especially the leaves of the lights installed behind the LED lights). Therefore, when the LED lights are turned on, it is difficult to see the leaves of the Christmas tree, resulting in poor decorative effects and failure to meet the growing needs of users. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model aims to provide an LED lamp for a Christmas tree.

[0005] The technical solution adopted by the utility model is as follows: an LED lamp for a Christmas tree, which is arranged on the Christmas tree, including an LED lamp, a first soldering pad and a second soldering pad. The LED lamps are two and are welded and packaged back to back at both ends of the first soldering pad and the second soldering pad to achieve 360° illumination; the lower ends of the first soldering pad and the second soldering pad respectively extend outward to form a positive pin and a negative pin for an external power supply.

[0006] In a preferred embodiment, the positive electrode wire and the negative electrode wire extending outward from the interior of the LED lamp are electrically connected to the positive electrode pin and the negative electrode pin respectively.

[0007] In a preferred embodiment, the LED lamp is a SMD LED lamp.

[0008] In a preferred embodiment, the LED lamp includes a base and an LED chip disposed in the base, the base is covered with a packaging layer that packages the LED chip and forms a light-emitting area, and the packaging layer is a fluorescent colloid.

[0009] In a preferred embodiment, a control chip electrically connected to the positive electrode wire, the negative electrode wire and the LED chip is also provided in the base of the LED lamp.

[0010] In a preferred embodiment, the operating voltage and current of the two LED lamps are the same.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the utility model, two SMD LED lights of the same voltage are welded back to back and packaged. When the LED lights are powered on, 360° lighting is achieved. When the LED lights of this structure are installed on the Christmas tree, they can not only meet the lighting effect of the LED lights, but also illuminate the Christmas tree, achieving a more beautiful Christmas tree colored light effect. In addition, fewer additional components are added, and the user effect is better, which is worthy of promotion.

[0013] 2. In the utility model, a control chip is designed in the LED lamp, which can be used to adjust the RGB mode of the LED lamp, or control the brightness of the LED, so as to achieve a more beautiful Christmas tree light effect, thereby improving the aesthetics and interest of the product.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] A LED light for a Christmas tree, referring to Figure 1-3, which is arranged on the Christmas tree, includes an LED lamp 1, a first soldering pad 2 and a second soldering pad 3. The LED lamps 1 are two and are welded and packaged at both ends of the first soldering pad 2 and the second soldering pad 3 in a back-to-back manner, so as to realize 360° illumination. The working voltage and current of the two LED lamps 1 are the same. The utility model welds and packages the two LED lamps 1 back to back. When the LED lamp 1 with such an LED structure is powered on, the light emitted by each LED lamp 1 will be 180 degrees of light. After the two are matched, 360° illumination can be achieved. When the LED structure with such a structure is installed on a Christmas tree (not shown in the figure), while satisfying the luminous effect of the LED lamp 1, it can also illuminate the Christmas tree, realizing a more beautiful Christmas tree colored light effect, and the user has a better use effect.

[0021] Furthermore, the lower ends of the first soldering pad 2 and the second soldering pad 3 respectively extend outward to form a positive pin 4 and a negative pin 5 for an external power supply (or a circuit board), and the positive wire and the negative wire (not shown in the figure) extending outward from the inside of the LED lamp 1 are respectively electrically connected to the positive pin 4 and the negative pin 5, and the two connecting wires are extended to connect to the power supply or the circuit board, so that the LED lamp 1 can achieve a lighting effect.

[0022] Furthermore, the LED lamp 1 includes a base and an LED chip (not shown) disposed in the base. The base is covered with a packaging layer 101 that packages the LED chip and forms a light-emitting area.
