Description

Technical Field

[0001] The utility model relates to an LED lamp, in particular to a bulb shell and a lamp using the bulb shell. Background Art

[0002] With the continuous evolution of modern home design, more and more users are beginning to pursue simple and streamlined decoration styles. Under this design trend, lamps are not only used as lighting tools, but also become an indispensable part of home decoration. The design of lamps needs to be coordinated with the overall home style to enhance the aesthetic feeling of the space and the quality of life.

[0003] As a common lighting device, the design of the bulb filament lamp also needs to keep up with the trend of the times and meet the aesthetic needs of users. However, in the design of traditional bulb filament lamps, the lamp holder is usually connected through the connection port on the bulb and placed outside the bulb. Although this design facilitates the replacement and maintenance of the lamp holder to a certain extent, it has certain shortcomings in terms of aesthetics, namely: the external lamp holder design destroys the overall aesthetics of the lamp. In modern home environments, especially in spaces that pursue simple and streamlined designs, the external lamp holder often appears abrupt and contradicts the sense of harmony and unity of the surrounding environment. Not only can it not be integrated with the home decoration style, it may also become a visual obstacle in the space, affecting the overall aesthetics; the design of the external lamp holder also limits the creative shape and diversity of the lamp. Since the lamp holder is external, the position and shape of the lamp holder need to be considered when conceiving the appearance of the lamp, which will affect the freedom and innovation of the design.

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Example 1: Please refer to Figure 1-15 As shown, the bulb shell described in the utility model comprises a bulb shell body 1, a through opening 11 is provided on the upper side of the bulb shell body 1, an inner tube 2 is provided inside the bulb shell body 1, and the upper end of the inner tube 2 is connected to the through opening 11; a connecting end 3 is provided inside the inner tube 2, and the lower end edge of the connecting end 3 is connected to the lower end of the inner tube 2. With the bulb shell of the structure described above, a power lamp holder or a power component can be placed inside the inner tube, and the light-emitting body is placed inside the bulb shell 10 and guided to take electricity to the power lamp holder or the power component. The interval formed by the inner tube sinking into the bulb shell just prevents the power lamp holder or the power component from being directly exposed to the outside, thereby partially or completely hiding the power lamp holder or the power component inside the inner tube, thereby improving the overall aesthetics of the lamp.

[0036] Please refer to Figure 4 As shown, the bulb body 1, the inner tube 2 and the connecting end 3 are all made of glass, the lower end edge of the connecting end 3 is sintered and fused with the lower end of the inner tube 2 to form an integrated structure, and the upper end of the inner tube 2 is sintered and fused with the through opening 11 to form an integrated structure. In actual operation, we generally sinter and combine the connecting end 3 with the inner tube 2 first, and then sinter and combine the inner tube 2 with the connecting end 3 with the bulb body 1.

[0037] Please refer to Figure 5 and 6 As shown, the bulb body 1 is a glass product, the inner tube 2 and the connecting end 3 are integrally injection-molded plastic parts, and the upper end of the inner tube 2 of the plastic part is connected to the through-port 11. The upper end of the inner tube 2 of the plastic part is provided with an outwardly provided ring rim 21, and the ring rim 21 is bonded to the rim of the through-port 11. A plurality of undercuts 22 are provided around the lower side of the ring rim 21, and the inner edge of the through-port 11 is guided and clamped in the clamping position formed between the ring rim 21 and the undercut 22 through the undercut 22, and a guiding slope 23 is provided on the undercut 22. The glass bulb body 1 retains the crystal clear light-transmitting effect of glass or crystal without the plastic texture; the inner tube and the connecting end are made of plastic for the purpose of simplifying the production and processing, facilitating assembly and mass production; and the purpose of designing the undercut 22 is to clamp the through-port 11, and then the lower side of the ring rim 21 and the upper side of the rim of the through-port 11 are sealed and bonded by glue or putty, and the connection reliability is strong.

[0038] Furthermore, the bulb body 1, the inner tube 2 and the connecting end 3 are an integrally formed structure of plastic blow molding, and the whole is made of light-transmitting or transparent plastic. For lighting fixtures that do not require glass texture, plastic blow molding can be used to make the bulb.

[0039] Example 2: Please refer to Figure 1-15 A lamp using the bulb shell includes a lamp holder 4 and a light emitter, wherein the lamp holder 4 is connected to the upper end of the connection end, and the light emitter is arranged below the lamp holder 4 in the bulb shell 10. The lamp holder is hidden in the countersunk hole, making the appearance of the lamp more concise and beautiful, and coordinating with the simple and streamlined style of modern home design.

[0040] The light emitter is a flexible LED filament 5, the lower end of which passes through the connection end and is vertically placed in the bulb shell 10, and the upper end of which is electrically connected to the lamp holder 4. Using a flexible LED filament as a light emitter not only provides a better lighting effect, but also increases the flexibility and diversity of the design.

[0041] A first magnetic component 7 is provided inside or outside the bottom of the bulb shell 10, and a second magnetic component 6 is connected to the lower end of the flexible LED filament 5. The flexible LED filament 5 is magnetically attracted to each other through the first magnetic component 7 and the second magnetic component 6 and is stretched straight in the bulb shell 10. Through the design of the magnetic component, the flexible LED filament can be stably stretched straight in the bulb shell, which not only ensures the lighting effect but also simplifies the installation process.

[0042] A driver 8 is disposed in the lamp holder 4 , and a power-taking end at the upper end of the flexible LED filament 5 forms a passage with the lamp holder 4 via the driver 8 .

[0043] The opening 11 of the bulb 10 is covered with a dust cover 9, and the dust cover 9 covers the upper end port of the inner tube 2, and a cable threading hole 90 is provided on the dust cover 9. By providing the dust cover 9, the lamp cap components in the inner tube 2 are effectively protected from dust and other pollutants. The lamp cap 4 is a screw-type lamp cap, which is screwed into the lamp cap seat 12. At the same time, the cable 121 at the upper end of the lamp cap seat 12 passes through the cable threading hole and is guided to the outside of the dust cover 9, and the dust cover 9 needs to be further pushed and covered on the tube opening of the inner tube 2.

[0044] Reference Figure 13-15As shown. The lamp holder 4 is screwed to the lamp base 13 of the chandelier, and the lamp base 13 of the chandelier is partially or completely placed in the interval formed by the inner tube 2 and the lamp holder 4. A gradient color coating or plating 14 is provided on the inner wall or outer wall of the bulb 10 on the side of the inner tube 2. In the traditional chandelier design, the lamp base is often visible, which may affect the overall aesthetics of the chandelier. By hiding the lamp base 13 in the interval formed by the inner tube 2 and the lamp base 4, and providing a gradient color coating or plating on the bulb 10, the appearance of the chandelier is more concise and beautiful; users cannot directly see the lamp base 2 and the inner tube 2, etc., which makes the overall design of the chandelier more streamlined and the visual effect is better.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
