Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a fluorescent lamp. Background Art

[0002] Existing fluorescent lamps usually include a lampshade, a plug shell, a circuit board and lamp beads. For example, the Chinese utility model patent with application number CN202220361202.9 discloses an LED fluorescent lamp, which includes a bracket for support and heat dissipation. End caps are installed at both ends of the bracket. The top of the bracket is provided with a trapezoidal groove for installing a strip light board. The two wings at the top of the bracket are provided with a strip slot for buckling the lampshade. The lampshade includes an arch shell. The left and right sides of the arch shell are bent inward with folded edges, and the folded edges are in contact with the horizontal bottom edge of the strip slot. The horizontal bottom edge and the folded edge are face to face with very little air between the two, forming a full contact state with strong adhesion and not easy to fall off. The limit clamping of the strip slot keeps the folded edge stably placed in the strip slot when no large external force is applied manually, solving the problem of easy separation of the lampshade and the bracket and reducing the risk of electric shock to the human body. The arched shell's curved structure mimics the shape of a traditional fluorescent tube, increasing the luminous angle and changing the direction of light emission to create an omnidirectional lighting effect. This improves the LED's light mixing effect and makes the light emission more uniform. In actual use, the heat generated by the lamp beads and circuit boards of this type of fluorescent lamp can only be dissipated directly through the lampshade. However, the long cylindrical bracket and end caps form a closed space, which has poor heat dissipation effect. A large amount of heat remains in the enclosed space, causing the internal temperature to rise. In addition, fluorescent lamps are usually installed on the ceiling, and if the back of the fluorescent lamp is too close to the ceiling, it will also affect the heat dissipation effect.

[0004] To this end, the present invention is achieved by adopting the following technical solutions:

[0021] Refer to the above attached Figure 1-2 As shown, the utility model provides a fluorescent lamp comprising a lamp housing and a plug shell 1 provided at both ends of the lamp housing, a circuit board is provided in the lamp housing, and a plurality of lamp beads are provided on the circuit board, and the characteristic is that: the lamp housing comprises a detachably connected heat dissipation bracket 2 and a lampshade 3, the front and rear sides of the heat dissipation bracket 2 are provided with a plurality of outwardly extending heat dissipation ribs 4, the heat dissipation bracket 2 is provided with two card slots 5 along its length direction, the heat dissipation bracket 2 is detachably provided with a plurality of elastic mounting brackets 6, the elastic mounting bracket 6 is provided with buckles 7 that can be snapped into the corresponding card slots 5 on both sides, and the elastic mounting bracket 6 is provided with mounting holes 8, and the mounting holes 8 are fixed to the ceiling by passing screws, the heat dissipation bracket 2 comprises a flat plate 9, the front and rear sides of the upper end of the flat plate 9 are provided with a first vertical plate 10, the inner side of the first vertical plate 10 is provided with a card plate 11, and the upper end of the flat plate 9 between the first vertical plates 10 is provided with two second vertical plates 12, and the second vertical plates 12, the first vertical plates 10 and the card plate 11 on the same side form the The card slot 5, the buckle 7 is provided with an opening 13 for the card plate 11 to be inserted and abutted, the heat dissipation rib 4 is arranged on the outside of the first vertical plate 10, and the two ends of the flat plate 9 are provided with downward third vertical plates 14, and L-shaped plates 15 are provided on both sides of the lower end of the flat plate 9. The L-shaped plate 15, the third vertical plate 14 and part of the flat plate 9 on the same side form a slot 16 for assembling the lampshade 3, the upper end of the lampshade 3 is inserted into the slot 16, and the upper end of the lampshade 3 is provided with a limit plate 17 bent inwardly, and the lower end of the limit plate 17 can abut against the inner wall of the L-shaped plate 15, the circuit board is attached to the lower end surface of the flat plate 9 between the two L-shaped plates 15 by glue or laser welding, the heat dissipation bracket 2 is formed by metal extrusion, or the heat dissipation bracket 2 is formed by aluminum extrusion, the plug shell 1 is provided with a through hole for the power cord to pass through, or the flat plate 9 between the two second vertical plates 12 is provided with a through hole for the power cord to pass through, or the lampshade 3 is provided with a through hole for the power cord to pass through.

[0022] In this embodiment, the heat dissipation bracket 2, the lamp housing, and the plug housing 1 do not form an enclosed space after being assembled, thereby improving the heat dissipation effect of the fluorescent lamp. In addition, multiple outwardly extending heat dissipation ribs 4 are provided on the front and rear sides of the heat dissipation bracket 2, greatly increasing the heat dissipation area. Even if the back of the fluorescent lamp is too close to the ceiling after installation, the heat generated by the lamp beads and the circuit board can still be dissipated through the heat dissipation ribs 4. When the fluorescent lamp is installed on the ceiling, the heat dissipation effect at the top of the fluorescent lamp is less affected, thereby ensuring the heat dissipation effect of the fluorescent lamp.

[0023] The mounting holes 8 of the elastic mounting bracket 6 are fixed to the ceiling by passing screws, and then the assembled fluorescent lamp is pushed upward so that the buckle 7 of the elastic mounting bracket 6 is snapped into the slot 5 of the heat dissipation bracket 2, thereby completing the fixation. The heat dissipation bracket 2 includes a flat plate 9, a first vertical plate 10, a card plate 11, and a second vertical plate 12. The second vertical plate 12, the first vertical plate 10, and the card plate 11 on the same side form a card slot 5. After the buckle 7 is snapped into the card slot 5, the card plate 11 is against the opening 13, and the structural stability is better. The heat dissipation bracket 2 of this structure is not only convenient for assembly and disassembly, but also more conducive to the heat dissipation of the fluorescent lamp. In addition, the existing ceiling-mounted installation is achieved by clamping the mounting bracket buckle on the outside of the lamp, which is not aesthetically pleasing. The buckle 7 cannot be seen after the fluorescent lamp provided by the utility model is installed, making the fluorescent lamp more beautiful.

[0024] The third vertical plate 14 not only enhances the heat dissipation effect of the side of the fluorescent lamp, but also forms a slot 16 with the L-shaped plate 15 and part of the flat plate 9 to accommodate the lampshade 3. The upper end of the lampshade 3, the limiting plate 17 and the slot 16 cooperate to achieve detachable installation. In addition, the third vertical plate 14 and the L-shaped plate 15 can limit the position of the lampshade 3. When the lampshade 3 is pressed inward or outward, it will not fall off the heat dissipation bracket 2, and the structural stability is better.

[0025] The circuit board is attached to the lower end surface of the flat plate 9 between the two L-shaped plates 15 by glue or laser welding. When the fluorescent lamp is working, the heat emitted by the lamp beads is directly transferred to the outside through the circuit board and the heat sink, which reduces the heat conduction link, lowers the thermal resistance, facilitates heat dissipation, and makes the heat dissipation effect of the fluorescent lamp better.

[0026] A through hole is provided on the plug shell 1 for the power cord to pass through; a through hole is provided on the flat plate 9 between the two second vertical plates 12 for the power cord to pass through; a through hole is provided on the lampshade 3 for the power cord to pass through; the utility model provides three ways of routing the power cord to meet the different needs of different users and has stronger applicability; in addition, when the power cord is passed through the through hole of the flat plate 9 between the two second vertical plates 12, the power cord can be routed in the space between the two second vertical plates 12, which can hide the power cord and make it more beautiful.
