Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and specifically refers to a festival light. Background Technology

[0002] Festive lights, as a common decorative lighting product, are widely used in festival celebrations, home decoration, and commercial displays. Traditional festive lights typically consist of a lamp holder, a lampshade, and an LED bulb body positioned between the two. The lead wire of the LED bulb body extends from the rear of the lamp holder and is connected in parallel with the adjacent LED bulb body.

[0003] However, in actual use, festive lights easily attract children's attention, and under the curious pull of children, the main body of the light bulb can easily detach from the lamp holder, causing small parts such as lampshade or lamp holder to fall off. If these small parts are accidentally swallowed by children, they can cause suffocation or other safety accidents, posing a serious safety hazard.

[0004] The reason why the main body of the LED bead is easy to detach from the lamp holder is that traditionally, the main body of the LED bead is fixed to the lamp holder with glue. When the main body of the LED bead is emitting light and heat, the glue is easy to soften, resulting in a weak connection between the main body of the LED bead and the lamp holder. To address this, a festival light disclosed in the existing Chinese utility model patent (authorization announcement number CN222335254U) includes a lamp holder and a lamp cover connected to the front end of the lamp holder. A lead wire is provided between the lamp cover and the lamp holder, and the LED bead passes through the rear end of the lamp holder. The lamp holder is a cylindrical structure, and its front inner wall has several limiting lips that can deform radially at their inner ends. The limiting lips form a conical channel with a front inner diameter smaller than the rear inner diameter. The outer diameter of the LED bead is smaller than the front inner diameter of the conical channel. The LED bead passes through the conical channel from back to front, and the rear end face of the LED bead can axially limit and abut against the inner end face of the limiting lips. This structure uses the radial deformation of the limiting lip to achieve unidirectional limiting. However, it is precisely because of the radial deformation structure of the limiting lip that when the lamp body is subjected to a large tensile force, the limiting lip will be unable to withstand the tensile force and will bend and fail to connect. Summary of the Invention

[0005] The purpose of this utility model is to provide a festival light with a simple structure, reasonable design and low cost. It achieves reliable and firm unidirectional limiting by means of the rigid contact between the limiting step surface and the limiting rear end surface.

[0006] This utility model is implemented as follows: A festive light includes a lamp holder and a lamp shade connected to the front end of the lamp holder. A lamp bead body is disposed between the lamp shade and the lamp holder. The lead wire of the lamp bead body extends backward out of the lamp holder. The lamp holder has a cylindrical structure and a limiting step surface with the end face facing forward is provided on the inner wall of its rear end. The lamp bead body has a limiting rear end face with the end face facing backward and can abut against the limiting step surface.

[0007] In the aforementioned type of festival light, the main body of the lamp bead includes a lamp bead element, the lead wire is electrically connected to the lamp bead element, and the lamp bead element and the lead wire are wrapped with a resin sleeve made of epoxy resin, the lower end face of which is the limiting rear end face.

[0008] In the aforementioned festival light, the diameter of the rear port of the lamp holder gradually expands from front to back to form a rear flared portion, the outer diameter of the resin sleeve is located between the maximum diameter and the minimum diameter of the rear flared portion, and the limiting step surface is located on the front side of the rear flared portion.

[0009] In the aforementioned type of festival light, the diameter of the front port of the lamp holder gradually decreases from front to back to form a front flared portion. The minimum diameter of the front flared portion is greater than the minimum diameter of the rear flared portion, and the front flared portion is connected to the rear flared portion through a limiting step surface.

[0010] In one of the aforementioned holiday lights, the contact area between the limiting rear end face and the limiting step face is greater than or equal to half the area of ​​the limiting rear end face.

[0011] The outstanding advantages of this utility model compared to the prior art are: This utility model has a simple structure, reasonable design and low cost. It achieves reliable and firm unidirectional limiting by means of the rigid contact between the limiting step surface and the limiting rear end surface. Attached Figure Description

[0014] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3: A festive light includes a lamp holder 1 and a lamp shade 2 connected to the front end of the lamp holder 1. A lamp bead body 3 is disposed between the lamp shade 2 and the lamp holder 1. The lead wire 7 of the lamp bead body 3 extends out of the lamp holder 1. The lamp holder 1 has a cylindrical structure and a limiting step surface 4 with the end face facing forward is provided on the inner wall of its rear end. The lamp bead body 3 has a limiting rear end face 5 with the end face facing backward and able to abut against the limiting step surface 4.

[0015] This utility model has a simple structure, reasonable design and low cost. It achieves reliable and firm unidirectional limiting by means of the rigid contact between the limiting step surface 4 and the limiting rear end surface 5.

[0016] Furthermore, the specific structure of the lamp bead body 3 is as follows: the lamp bead body 3 includes a lamp bead element 6, the lead wire 7 is electrically connected to the lamp bead element 6, and the lamp bead element 6 and the lead wire 7 are wrapped with a resin sleeve 8 made of epoxy resin, the lower end face of the resin sleeve 8 being the limiting rear end face 5.

[0017] The method for assembling the lamp bead body 3 between the lamp cover 2 and the lamp holder 1 can be as follows: when the lamp cover 2 and the lamp holder 1 are separated, the lamp bead body 3 and the lead wire 7 can be inserted into the lamp holder 1 from front to back until the limiting rear end face 5 abuts against the limiting step face 4. Thus, the lead wire 7 of the lamp bead body 3 passes out of the lamp holder 1 and is connected in parallel with the lead wire 7 of the adjacent lamp bead body 3.

[0018] In this embodiment, the main body of the lamp bead 3 is connected in parallel with the adjacent main body of the lamp bead 3 through the lead wire 7, thereby forming a long string structure. Therefore, in this embodiment, the specific fitting structure of the main body of the lamp bead 3 in the string structure between the lamp cover 2 and the lamp holder 1 is as follows: the diameter of the rear port of the lamp holder 1 gradually expands from front to back to form a rear flared part 9, the outer diameter of the resin sleeve 8 is located between the maximum diameter and the minimum diameter of the rear flared part 9, and the limiting step surface 4 is located on the front side of the rear flared part 9. The resin sleeve 8, made of annular resin, has a certain radial deformation. During the process of inserting the lamp bead body 3 and lead wire 7 from back to front into the lamp holder 1, the lamp bead body 3 smoothly passes through the rear flared portion 9 of the lamp holder 1 due to the radial deformation of the resin sleeve 8. Since the resin sleeve 8 wraps around or is looped around the lamp bead element 6 and lead wire 7, its axial deformation is low. Furthermore, the surface contact force between the limiting step surface 4 and the limiting rear end surface 5 is axial. Therefore, the resin sleeve 8 cannot undergo radial deformation and detach downwards from the lamp holder 1. Thus, the unidirectional limiting structure between the lamp holder 1 and the lamp bead body 3 is stable and reliable. In order to facilitate the insertion and fixing of the lampshade 2 to the front port of the lamp holder 1, the diameter of the front port of the lamp holder 1 gradually decreases from front to back to form a front flared part 10. The minimum diameter of the front flared part 10 is greater than the minimum diameter of the rear flared part 9, and the front flared part 10 is connected to the rear flared part 9 through the limiting step surface 4.

[0019] Furthermore, in order to ensure effective surface-to-surface contact and abutment between the limiting rear end surface 5 and the limiting step surface 4, the abutment contact area between the limiting rear end surface 5 and the limiting step surface 4 is greater than or equal to half the area of ​​the limiting rear end surface 5.

[0020] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
