[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] refer to Figures 1 to 24 This utility model provides a light bulb 10, which can be used as a string of lights to create a festive atmosphere. Of course, the light bulb 10 can also be used for other purposes, which are not limited by this utility model.

[0055] The light bulb 10 includes a bulb housing 100, a mounting base 200, a bulb plate 300, and a conductive component 400.

[0056] The lamp housing 100 includes a base 110 and a lamp cover 120. The base 110 is provided with a first power receiving part 111 and a second power receiving part 112. The fixing seat 200 is located inside the base 110 and is provided with a plug-in slot 210. The lamp board 300 includes a light-emitting substrate 310 and a light source 320 disposed on the light-emitting substrate 310. The light-emitting substrate 310 can be plugged into the plug-in slot 210 of the fixing seat 200. The conductive component 400 connects the lamp board 300 and the power receiving part.

[0057] Understandable, for reference Figure 2 and Figure 3 In some embodiments, the fixing base 200 and the base 110 are integrally formed, and the fixing base 200 is a part of the base 110; see reference. Figure 23 In other embodiments, the mounting base 200 is detachably mounted on the inner wall of the base 110.

[0058] The conductive component 400 includes a first conductive element 410 and a second conductive element 420. When the light-emitting substrate 310 is inserted into the insertion slot 210, the two ends of the first conductive element 410 abut against the first contact part 111 and connect to the light-emitting substrate 310, respectively, and the two ends of the second conductive element 420 abut against the second contact part 112 and connect to the light-emitting substrate 310, respectively.

[0059] In this embodiment of the utility model, one end of the conductive element abuts against the power receiving part on the base 110. When the light source 320 is damaged, the light-emitting substrate 310 inside the lamp housing 100 can be removed and replaced without replacing the entire bulb 10.

[0060] In some embodiments, the lamp panel 300 is detachably inserted into the insertion slot 210, allowing for individual replacement of the lamp panel 300.

[0061] refer to Figure 2 and Figure 3 Specifically, the base 110 is provided with a first hole 113 that is adapted to the first electrical contact part 111 and a second hole 114 that is adapted to the second electrical contact part 112. The first conductive member 410 passes through the first hole 236 and is connected to the first electrical contact part 111, and the second conductive member 420 passes through the second hole 114 and is connected to the second electrical contact part 112.

[0062] refer to Figures 1 to 4 Specifically, the first conductive element 410 is a first metal wire 411, the second conductive element 420 is a second metal wire 421, and the light-emitting substrate 310 includes a first electrode 311 and a second electrode 312 disposed at intervals. The first metal wire 411 is connected to the first electrode 311 on the light-emitting substrate 310, and the second metal wire 421 is connected to the second electrode 312 on the light-emitting substrate 310. Figure 4The diagram shows that one end of the first metal wire 411 abuts against the first electrode 311, and one end of the second metal wire 421 abuts against the second electrode 312, to facilitate the insertion and replacement of the lamp board 300.

[0063] refer to Figure 5 In another embodiment, one end of the first metal wire 411 is welded to the first electrode 311, and one end of the second metal wire 421 is welded to the second electrode 312. This arrangement ensures that the metal wires maintain a stable electrical connection with the light-emitting substrate 310, preventing the metal wires from losing contact with the light-emitting substrate 310.

[0064] refer to Figure 6 and Figure 7 The first conductive element 410 and the second conductive element 420 are both metal sheets 430. The metal sheet 430 includes a snap-fit ​​piece 431 that snaps onto the light-emitting substrate 310 and a contact piece 432 that abuts against the contact portion.

[0065] refer to Figure 6 Specifically, the snap-fit ​​piece 431 is provided with a slot 4311, and the light-emitting substrate 310 includes a first electrode 311 and a second electrode 312 spaced apart. Each electrode can be inserted into the corresponding slot 4311 to achieve a detachable connection between the lamp board 300 and the fixing base 200, while maintaining a stable electrical connection. It can be understood that in other embodiments, the slot 4311 can also be provided on the light-emitting substrate 310, and the contact piece 432 can be detachably inserted into the slot 4311 on the light-emitting substrate 310.

[0066] refer to Figure 7 Specifically, the outer wall of the snap-fit ​​piece 431 is provided with a protrusion 4312, and both the first electrode 311 and the second electrode 312 are provided with a limiting hole 313 that is adapted to the protrusion 4312. At least a portion of the protrusion 4312 is embedded in the limiting hole 313 to achieve a detachable connection between the snap-fit ​​piece 431 and the light-emitting substrate 310 and maintain a stable electrical connection.

[0067] Furthermore, both the protrusion 4312 and the limiting hole 313 are arc-shaped. This design facilitates the entry of the protrusion 4312 into the limiting hole 313, making assembly more convenient. Of course, in other embodiments, the protrusion 4312 and the limiting hole 313 can also be configured with other shapes, such as square, conical, etc.

[0068] In some embodiments, the outer diameter of the base 110 is smaller than the outer diameter of the lamp cover 120. The base 110 and the lamp cover 120 are sealed together, and there is a connecting line 130 between the base 110 and the lamp cover 120. The sealed connection can achieve a waterproof effect. That is to say, the base 110 and the lamp cover 120 are molded separately and then sealed together to form a whole.

[0069] Since the lamp housing 100 is generally a transparent plastic shell formed by blow molding, the size of the opening in the blow molding process affects the processing difficulty and cost. In the case of a one-piece molded lamp housing 100, the opening is set at the top of the base 110 during blow molding. In this embodiment, the base 110 and lamp cover 120 are molded separately. During blow molding, the opening is set between the base 110 and the lamp cover 120, that is, at the position of the connecting line 130. The diameter of the opening is larger, which reduces the processing difficulty of the lamp cover 120. The mature welding process is fast and low-cost, which makes the total cost of the separately molded lamp housing 100 lower and the molding quality better.

[0070] In this embodiment, the base 110 and the lamp cover 120 are connected together by ultrasonic welding. Of course, the manufacturer can also use other connection methods as needed.

[0071] refer to Figure 5 and Figure 6 Specifically, both the first conductive element 410 and the second conductive element 420 are provided with a bending portion 450 to change the extension direction of the first conductive element 410 and the second conductive element 420, so as to facilitate contact with the contacting part. The bending angle can be 90 degrees or other angles.

[0072] refer to Figures 1-11 and Figures 14-20 Specifically, in some embodiments, the first electrical contact 111 is a metal cap, and the second electrical contact 112 is an annular metal sheet. The metal cap and the metal sheet are spaced apart. The metal cap is snapped onto the top of the base 110, and the metal sheet is snapped onto the outer wall of the base 110.

[0073] With this configuration, when the metal cap and metal sheet are installed on the base 110, the metal cap can be aligned with the first conductive element 410 at any angle, and the metal sheet can be aligned with the second conductive element 420 at any angle.

[0074] refer to Figure 2 and Figure 18 In one embodiment, the base 110 includes a base body 113 and a conical portion 115 arranged in sequence, a metal cap pin is engaged with the top of the conical portion 115 and extends into the interior of the base 110, and a metal buckle is engaged with the lower edge of the conical portion 115.

[0075] Furthermore, the metal skin includes an integrally formed snap-fit ​​portion 1121 and a cover portion 1122. The inner diameter of the snap-fit ​​portion 1121 is smaller than the inner diameter of the cover portion 1122. The snap-fit ​​portion 1121 snaps onto the lower edge of the tapered portion 115, and the cover portion 1122 covers the outer wall of the base 110.

[0076] refer to Figure 9 , Figure 11 , Figure 15 , Figure 18 and Figure 20 In one embodiment, the base 110 is provided with a boss 114 and a tapered portion 115. The outer diameters of the base body 113, the boss 114 and the tapered portion 115 decrease sequentially to facilitate the inclined portion to be inserted into and abut against the metal sheet.

[0077] The metal cap is engaged with the tapered portion 115 and extends into the base 110. The metal sheet includes an integrally formed engaging portion 1121 and a covering portion 1122. The inner diameter of the engaging portion 1121 is smaller than the inner diameter of the covering portion 1122. The engaging portion 1121 is engaged with the outer wall of the boss 114 to make the connection between the metal sheet and the base 110 more secure.

[0078] refer to Figure 11 and Figure 20 Furthermore, the base 110 has a recessed limiting groove 1131 on its outer wall near the boss 114. The limiting groove 1131 extends continuously along the circumference of the base body 113, and a limiting strip 1123 is provided inside the cover 1122. At least a portion of the limiting strip 1123 is embedded in the limiting groove 1131. This arrangement prevents the metal sheet from detaching from the base 110.

[0079] refer to Figure 13 , Figure 22 and Figure 23 Specifically, in some embodiments, the bulb 10 further includes a metal head 500, which is sleeved on the top of the base 110. The metal head 500 includes a protruding first contact portion 111 and an annular second contact portion 112. An insulating portion 510 is provided between the first contact portion 111 and the second contact portion 112 so that the first contact portion 111 and the second contact portion 112 are spaced apart and insulated from each other.

[0080] Furthermore, the inner wall of the metal head 500 is provided with internal threads, and the outer wall of the base 110 is provided with external threads. The metal head 500 is detachably sleeved onto the base 110 through threaded engagement.

[0081] In this embodiment of the utility model, the first electrical contact 111, the second electrical contact 112, the first conductive element 410, the second conductive element 420, the metal cap, the metal skin, and the metal head 500 are all made of copper, which has good conductivity and low cost. Of course, if conductivity and cost are not considered, conductive materials such as silver, aluminum, and iron can also be used.

[0082] refer to Figures 13-23 Specifically, the base 110 is provided with a filling position 140, which is located at one end of the conductive component 400 near the base 110. The filling position 140 is filled with waterproof adhesive to prevent the part of the conductive component 400 exposed at the connection from coming into contact with external water.

[0083] refer to Figures 14-23Specifically, the bulb 10 also includes a waterproof rubber ring 600, which is located between the outer wall of the mounting base 200 and the inner wall of the base 110 to prevent moisture from entering the lamp cover 120 and contacting the lamp plate 300.

[0084] Understandable, except Figures 1 to 23 The lamp cover 120 shown in the illustration can also be configured with other lamp covers 120 of various shapes, such as... Figure 24 The illustration shows several lamp covers of different shapes 120.

[0085] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
