Description

lamps Technical Field

[0001] The invention relates to a lamp. Background Art

[0002] CN 218762905 U and CN 218494908 U both disclose a lamp comprising a lamp housing and a flexible filament located within the lamp housing. The filament has a fixed end and a free end. The fixed end of the filament is fixed to one end of the lamp housing, and the other end of the filament is a free end. A magnet is disposed on the free end, and a magnet corresponding to the magnet at the free end of the filament is disposed on the base of the lamp housing. When the two magnets correspond, the filament is straightened; when the two magnets do not correspond, the filament is relaxed. This structure of the lamp prevents the filament from immediately vibrating when an external impact on the lamp body occurs. Instead, the filament is deformed and the magnetic attraction between the two magnets is interrupted, providing buffering protection. This prevents the lamp body from experiencing excessive instantaneous momentum after an impact, which could easily cause the filament to break due to tension. This improves the product reliability of the lamp. Technical issues

[0003] Another disadvantage is that although the magnetic structure is used to prevent the filament from immediately vibrating when external forces act on the lamp body, the lamp may be in an unstable state at any time during transportation or other processes. At this time, the filament is very likely to be in an unstable state for a long time, that is, the two magnets are opposite to each other and the filament is in a straightened state, and the magnetic attraction between the two magnets is disconnected and the filament is in a relaxed state. This unstable state will affect the service life of the filament. Technical Solutions

[0004] In order to overcome the above-mentioned deficiencies of the existing lamps, the present invention provides a lamp with a stable filament state.

[0005] The technical solution of the present invention to solve its technical problem is: a lamp includes a lamp housing, a flexible filament located in the lamp housing, and a control board located in the lamp housing, the filament having a first fixed end and a second fixed end, the first fixed end of the filament being fixed to the lamp housing and / or the control board, and the second fixed end being fixed to the lamp housing.

[0009] Furthermore, the elastic member is an elastic sheet.

[0011] Furthermore, a thick positioning ring is provided on the edge of the elastic sheet, and the thick positioning ring is clamped between the lamp housing and the clamping sheet.

[0012] Furthermore, the second fixed end passes through the elastic sheet and is connected thereto.

[0013] Furthermore, the second fixed end passes through the elastic sheet and is connected to a positioning bead, so that the second fixed end is positioned by the positioning bead.

[0015] Furthermore, the elastic sheet is arranged in the first lamp housing, and the first lamp housing is provided with an opening corresponding to the positioning bead.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Referring to Figures 1, 2, 3, 4, and 5, a lamp includes a lamp housing 1, a flexible filament 2 located within the lamp housing 1, and a control board 3 located within the lamp housing 1. The filament 2 has a first fixed end 4 and a second fixed end 5. The first fixed end 4 of the filament 2 is fixed to the control board 3, or the first fixed end is connected to the control board and then fixed to the lamp housing, or the first fixed end is fixedly connected to both the lamp housing and the control board. In short, the first fixed end 4 is fixed.

[0027] The second fixed end 5 is fixed to the lamp housing, that is, the second fixed end 5 is also fixed, so that the first fixed end 4 and the second fixed end 5 of the filament are both fixed, so that the filament can be kept in a stable state even during bumpy transportation.

[0028] Typically, one end of the filament 2 serves as the first fixed end 4, and the other end of the filament 2 serves as the second fixed end 5, so that the filament 2 is straight within the lamp housing, which is the most stable state. Of course, the first and second fixed ends can also be set to other positions, for example, with both ends of the filament serving as the first fixed end and the middle bend of the filament serving as the second fixed end, so that the filament is U-shaped within the lamp housing.

[0029] In one embodiment, the second fixed end 5 is elastically connected to the lamp housing 1. Under the action of the elastic connection, the second fixed end 5 and the lamp housing 1 are not rigidly fixed, which means that even if the lamp is subjected to a large impact, since the second fixed end 5 and the lamp housing 1 are elastically connected, there is room for buffering between the second fixed end 5 and the lamp housing 1, and the filament can be prevented from being broken under the action of the spring buffer.

[0030] Generally speaking, the second fixing end 5 and the lamp housing 1 are connected via an elastic member to achieve the purpose of elastic connection between the two.

[0031] In one embodiment, the elastic member is a spring, that is, one end of the spring is connected to the second fixed end of the filament, and the other end of the spring is connected to the lamp housing. Of course, the elastic member can also be other forms, such as an elastic rubber band.

[0032] In one embodiment, the elastic member is an elastic sheet 6, and the second fixed end 5 of the filament is connected to the elastic sheet 6. The elastic sheet 6 can be a rubber sheet or a silicone sheet. The fixing method of the elastic sheet 6 can be bonding, connecting with fasteners such as screws, etc. In one embodiment, the specific fixing method of the elastic sheet 6 is: the elastic sheet 6 is clamped between the lamp housing 1 and the clamping sheet 7 through the clamping sheet 7, and the clamping sheet 7 is fixedly connected to the lamp housing 1 (for example, connected with fasteners such as screws, etc.). In one embodiment, the edge of the elastic sheet 6 is also provided with a circle of thick positioning ring 12, and the thick positioning ring 12 is clamped between the lamp housing 1 and the clamping sheet 7. The thick positioning ring 12 is relatively thick and can be clamped better, and can also reduce the adverse effects of directly clamping the elastic sheet on the elastic sheet.

[0033] The second fixed end 5 of the filament can be connected to the elastic sheet 6 by passing the second fixed end 5 through the elastic sheet 6 and then connecting thereto, thereby providing a more stable connection. In one embodiment, the second fixed end 5 can be connected to a positioning bead 8 after passing through the elastic sheet 6, thereby achieving positioning of the second fixed end through the positioning bead 7, thereby providing a more stable connection. The second fixed end 5 can pass through the elastic sheet and then be tied through the positioning bead, or it can be passed through the positioning bead and then bonded to the positioning bead, which can also be further bonded to the elastic sheet.

[0034] In one embodiment, the lamp housing 1 includes a first lamp housing 1-1 and a second lamp housing 1-2. The first lamp housing 1-1 and the second lamp housing 1-2 are matched to form the lamp housing 1. The lamp housing 1 can be divided into the first lamp housing 1-1 and the second lamp housing 1-2 to facilitate the installation of the filament 2.

[0035] In one embodiment, the elastic sheet 6 is disposed within the first lamp housing 1-1. An opening 9 corresponding to the positioning bead 8 is provided on the first lamp housing 1-1 to facilitate installation of the positioning bead 8. After the filament passing through the elastic sheet 6 and the elastic sheet 6 are installed using the clamping sheet 7, the positioning bead 8 can be installed through the opening 9. For aesthetics and dust prevention, a shielding plate 10 is provided over the opening 9.

[0036] The cross section of the lamp housing 1 can be set to a polygon with arc chamfers 11 at the corners of the polygon. The light emitted by the filament 2 can produce a special optical effect at the arc chamfers 11 to generate a light spot, thereby enhancing the decorative effect of the lamp.

[0037] The shape of the lamp housing is not limited. For example, the lamp housing in FIG1 is cylindrical, while FIG4 is prismatic. FIG4 also includes a carrying strap for easy carrying. The lamp of the present invention can be a ceiling lamp, a decorative lamp placed on a table or the floor, or a table lamp. For example, FIG5 shows a table lamp with a lamp pole and base attached to the lamp housing.
