Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] This utility model relates to a retractable disc-shaped decorative light bulb, including a lamp housing 100 and a light source component 200.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the lamp housing 100 can be cylindrical, polygonal, or other shapes. One end of the lamp housing 100 is open, and the other end is closed, with a hollow interior forming a mounting cavity 110. Partially or entirely, the lamp housing 100 is made of a light-transmitting material. At least two lamp housings 100 are provided, and there can be two, three, or more. The lamp housings 100 are connected sequentially, with the outer diameter of each lamp housing 100 decreasing progressively. The shapes of the lamp housings 100 can be similar or dissimilar; for example, all lamp housings 100 can be cylindrical, or some lamp housings 100 can be cylindrical while the rest are polygonal. In two adjacent lamp housings 100, one has a larger outer diameter than the other. The lamp housing with the larger outer diameter is fitted onto the lamp housing with the smaller outer diameter, and the two can move relative to each other. The lamp housing with the smaller outer diameter can move to the inside or outside of the mounting cavity 110 corresponding to the lamp housing with the larger outer diameter. It should be noted that the outer diameter of the lamp housing 100 is not limited to the maximum or minimum outer diameter of the lamp housing 100. For example, if the lamp housing 100 is cylindrical, then the outer diameter is the diameter of the outer peripheral wall of the cylindrical lamp housing 100. If the lamp housing 100 is set as a polygon or other shape, the outer diameter of these lamp housings 100 can be the maximum or minimum outer diameter of the lamp housing 100, as long as the smaller lamp housing 100 can be retracted into the mounting cavity 110 of the larger lamp housing 100. This embodiment uses three lamp housings 100 connected in sequence as an example for illustration. For ease of explanation, the three lamp housings 100 are defined as the first housing 101, the second housing 102, and the third housing 103, respectively. The first housing 101, the second housing 102, and the third housing 103 are set as cylindrical, and the first housing 101, the second housing 102, and the third housing 103 are connected in sequence. The outer diameter of the first housing 101 is the largest, the outer diameter of the second housing 102 is the second largest, and the outer diameter of the third housing 103 is the smallest. The first housing 101 is fitted over the second housing 102, and the second housing 102 is fitted over the third housing 103. As shown in the diagram, the second housing 102 can move vertically relative to the first housing 101. When the second housing 102 moves upward, it retracts into the mounting cavity 110 of the first housing 101; when the second housing 102 moves downward, it extends downward out of the mounting cavity 110 of the first housing 101 but does not detach from the first housing 101. The third housing 103 can move vertically relative to the second housing 102. When the third housing 103 moves upward, it retracts into the mounting cavity 110 of the second housing 102; when the third housing 103 moves downward, it extends downward out of the mounting cavity 110 of the second housing 102 but does not detach from the second housing 102. At least one of the housings 100 has a lamp source 200 mounted in its mounting cavity 110. The lamp source 200 extends out of the first housing 101 via a wire and is connected to an external power source for illumination. In use, as... Figure 1 As shown, the first housing 101 is pulled downward relative to the second housing 102, and the second housing 102 is pulled downward relative to the first housing 101, so that the bulb as a whole forms a three-layer tower-like structure, and the light generated by the light source 200 is projected outward through each housing 100. Figure 4 As shown, when packaging, transporting, and storing the bulb, the third housing 103 is retracted into the mounting cavity 110 of the second housing 102, and the second housing 102 is retracted into the mounting cavity 110 of the first housing 101. This is equivalent to the remaining bulb housings 100 being hidden in the mounting cavity 110 of the bulb housing 100 with the largest outer diameter, which reduces the overall volume of the bulb, effectively reduces space occupation, lowers transportation and storage costs, and makes it very convenient to use.

[0030] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, among the two adjacent lamp housings 100, the one with the larger outer diameter has a connecting surface 120, on which a mounting hole 121 communicating with the mounting cavity 110 is provided. The one with the smaller outer diameter has a raised edge 130 around its periphery, and the smaller outer diameter passes through the mounting hole 121. In this embodiment, the lower end face of the first housing 101 is the connecting surface 120, and the connecting surface 120 has a mounting hole 121. The lower end face of the second housing 102 is also the connecting surface 120, and the connecting surface 120 has a mounting hole 121. The second housing 102 and the third housing 103 both have raised edges 130 around their peripheries. The second housing 102 extends and retracts relative to the mounting cavity 110 of the first housing 101 through the mounting hole 121. The third housing 103 extends and retracts relative to the mounting cavity 110 of the second housing 102 through the mounting hole 121. When the smaller outer diameter extends into the mounting cavity 110 corresponding to the larger outer diameter, the protruding edge 130 can move to abut against the inner wall of the mounting cavity 110. That is, when the second housing 102 extends downward relative to the first housing 101, the protruding edge 130 of the second housing 102 moves downward with the second housing 102 to abut against the inner wall of the mounting cavity 110 of the first housing 101, thereby limiting the downward travel position of the second housing 102 relative to the first housing 101 and preventing the second housing 102 from detaching from the first housing 101 during downward movement. When the third housing 103 extends downward relative to the second housing 102, the protruding edge 130 of the third housing 103 moves downward with the third housing 103 to abut against the inner wall of the mounting cavity 110 of the second housing 102, thereby limiting the downward travel position of the third housing 103 relative to the second housing 102 and preventing the third housing 103 from detaching from the second housing 102 during downward movement.

[0031] Based on the above embodiments, the protruding edge 130 extends circumferentially along the lamp housing 100 in an annular shape. When the protruding edge 130 moves to abut against the inner wall of the mounting cavity 110, the protruding edge 130 cooperates with the lamp housing 100 to cover the mounting hole 121. In this embodiment, when the second housing 102 moves to its lowest position relative to the first housing 101, the protruding edge 130 abuts against the inner wall of the mounting cavity 110 of the first housing 101. The annular outer diameter formed by the protruding edge 130 of the second housing 102 is larger than the mounting hole 121 of the first housing 101. The protruding edge 130 of the second housing 102, together with the second housing 102 itself, covers and seals the mounting hole 121 of the first housing 101. When the third housing 103 moves to its lowest position relative to the second housing 102, the protruding edge 130 abuts against the inner wall of the mounting cavity 110 of the second housing 102. The annular outer diameter formed by the protruding edge 130 of the third housing 103 is larger than the mounting hole 121 of the second housing 102. The protruding edge 130 of the third housing 103, together with the third housing 103 itself, covers and seals the mounting hole 121 of the second housing 102. This prevents light leakage from the mounting hole 121 when the light source 200 emits light, and also prevents dust and insects from entering the mounting cavity 110 through the mounting hole 121.

[0032] In this embodiment, when the smaller outer diameter of one of the two adjacent lamp housings 100 retracts into the mounting cavity 110 of the larger outer diameter to its limit position, the end face of the smaller outer diameter is flush with the connecting surface 120. Similarly, when the second housing 102 retracts into the mounting cavity 110 of the first housing 101 to its highest position, the outward-facing lower end face of the second housing 102 is flush with the connecting surface 120 of the first housing 101. Likewise, when the third housing 103 retracts into the mounting cavity 110 of the second housing 102 to its highest position, the outward-facing lower end face of the third housing 103 is flush with the connecting surface 120 of the second housing 102. This prevents parts of the third housing 103 from protruding from the second housing 102 and parts of the second housing 102 from protruding from the first housing 101, facilitating the stacking of multiple bulbs during packaging and storage.

[0033] In one embodiment, such as Figure 2 and Figure 5As shown, in two adjacent lamp housings 100, the mounting cavity 110 of the one with the larger outer diameter is provided with a guide post 140, and the guide post 140 is provided with a guide groove 141. In this embodiment, the mounting cavity 110 of the first housing 101 is provided with a guide post 140, and the mounting cavity 110 of the second housing 102 is provided with a guide post 140. One, two, or more guide posts 140 can be provided in the corresponding mounting cavities 110. The guide groove 141 extends along the direction of relative movement between the two adjacent lamp housings 100, that is, it extends in the vertical direction as shown in the figure. The one with the smaller outer diameter is provided with a guide block 150, which is slidably connected to the guide groove 141. The outer walls of the second housing 102 and the third housing 103 are provided with guide blocks 150. The guide block 150 of the second housing 102 slides in the guide groove 141 of the first housing 101, and the guide block 150 of the third housing 103 slides in the guide groove 141 of the second housing 102. The guide block 150 and guide groove 141 work together to guide the relative movement of the second housing 102 and the first housing 101, as well as the relative movement of the third housing 103 and the second housing 102, and to restrict relative rotation between the lamp housings 100. Each mounting cavity 110 contains a lamp source component 200. After installation, the lamp source component 200 abuts against the upper end of the guide post 140 and seals the upper end of the corresponding guide groove 141. This prevents the guide block 150 from disengaging from the guide groove 141 when it moves upward relative to it.

[0034] In one embodiment, such as Figure 2 and Figure 3 As shown, the lamp housing 100 with the largest outer diameter includes a cover plate 160 and a light-transmitting housing base 170. In this embodiment, the first housing 101 has the largest outer diameter and includes a cover plate 160 and a housing base 170. The cover plate 160 covers the upper side of the housing base 170, defining a mounting cavity 110 between the cover plate 160 and the housing base 170. The housing base 170 is sleeved on the lamp housing 100 (second housing 102) adjacent to the lamp housing 100 with the largest outer diameter. A lamp source component 200 is installed in the mounting cavity 110 corresponding to the lamp housing 100 with the largest outer diameter. The lamp source component 200 abuts against the side wall of the cover plate 160 facing the mounting cavity 110, and the heat generated by the lamp source component 200 when emitting light can be effectively dissipated through the cover plate 160. The light source component 200 can be directly mounted on the cover plate 160, or it can be fixed in the housing 170 through other structures and then abutted against the cover plate 160, for example, as shown below. Figure 2 , Figure 5 and Figure 6As shown, the mounting cavity 110 is provided with mounting posts 180. One, two or more mounting posts 180 can be provided, and the mounting posts 180 can be formed on the guide posts 140. The lamp source component 200 includes an aluminum substrate 210 and lamp beads 220 integrated on the aluminum substrate 210. The aluminum substrate 210 and the mounting posts 180 are fixedly connected by screws or clips.

[0035] Based on the above embodiments, such as Figure 2 and Figure 3 As shown, each mounting cavity 110 houses a lamp source 200, and each lamp source 200 projects light outward through its corresponding lamp housing 100. The lamp housings 100 are coaxially connected in sequence, and the aluminum substrates 210 are coaxially positioned. Among two adjacent aluminum substrates 210, the aluminum substrate 210 installed in the lamp housing 100 with the larger outer diameter has a through hole 211, and the diameter of the through hole 211 in the aluminum substrate 210 installed in the lamp housing 100 with the larger outer diameter is larger than the outer diameter of the aluminum substrate 210 installed in the lamp housing 100 with the smaller outer diameter. In this embodiment, the aluminum substrate 210 installed in the first housing 101 has the largest outer diameter; this aluminum substrate 210 is annular, with a through hole 211 in its central portion. The aluminum substrate 210 installed in the second housing 102 is annular, and its outer diameter is smaller than the diameter of the through hole 211 in the aluminum substrate 210 installed in the first housing 101. The aluminum substrate 210 in the third housing 103 can be configured as an annular or disc-shaped structure, with its outer diameter smaller than the diameter of the through-hole 211 of the aluminum substrate 210 installed in the second housing 102. When the second housing 102 moves relative to the first housing 101, the through-hole 211 of the aluminum substrate 210 in the first housing 101 avoids the aluminum substrate 210 of the second housing 102. When emitting light, the LEDs 220 on these two aluminum substrates 210 are staggered and do not overlap, thus avoiding ghosting. When the third housing 103 moves relative to the second housing 102, the through-hole 211 of the aluminum substrate 210 in the second housing 102 avoids the aluminum substrate 210 of the third housing 103. When emitting light, the LEDs 220 on these two aluminum substrates 210 are staggered and do not overlap, thus avoiding ghosting.
