Description

Technical Field

[0001] The utility model belongs to the technical field of daily lighting, in particular to a hanging lighting lamp. Background Art

[0002] As one of the essential daily tools in people's daily life, lighting is suitable for various indoor activity places such as homes, supermarkets, etc.

[0003] The heat dissipation effect of a lighting lamp is an important factor affecting its service life. In the prior art, materials with heat dissipation properties, such as metal or ceramic, are used to make the lighting lamp body, and the heat is completely dissipated by the material itself during the lighting process. However, due to the heavy weight of these materials, the lighting lamp is overall heavy and inconvenient to assemble. Moreover, after long-term use, it is found that the heat dissipation effect of the lighting lamp is not good.

[0004] Therefore, patent CN204300825U, the patent name is "An explosion-proof LED lighting lamp", which proposes a technical solution to the above problems. Combining the claims and the drawings of the specification of the technical solution, it can be seen that the technical solution is to fix the light source housing, the power supply housing and the wiring housing with screws. This installation method relies entirely on screws, so a large number of screws are required, and the screw sizes of each connecting part are different, so there will be problems such as some screws being lost or the assembly taking a long time. In addition, the use of screws to fix the connection makes there is no gap between the two adjacent housings, which is not conducive to good heat dissipation of the lighting lamp.

[0005] Furthermore, the above-mentioned prior art installs the lamp body into the light source cavity. Since the lamp board will generate heat during use, and the heat dissipation in this technical solution completely relies on the heat sink on the periphery of the light source shell, the heat in the middle of the lighting lamp can only be transported upward, but due to the cavity above it, the heat will be concentrated in the cavity and cannot be dissipated. Over time, condensation beads will form, affecting the service life and safety of the lighting lamp.

[0006] Therefore, designing a lighting lamp with good heat dissipation and high safety factor is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0030] like Figure 1 to Figure 2 As shown, the utility model discloses a hanging lighting lamp, comprising a light source housing 1 and a power supply housing 2; wherein a lighting lamp board 11 is centrally arranged in the light source housing 1. The light source housing 1 comprises an integrally arranged lamp board installation area 101 and a lighting connection area 102, which are arranged at intervals and connected by a connecting bridge 103. The integrity and strength of the light source housing 1 can be enhanced by the connecting bridge 103. Furthermore, the lighting connection area 102 is located at the periphery of the lamp board installation area 101. A group of heat sinks 12 are arranged on the upper surface of the light source housing 1; the heat sinks 12 are located on the upper surface of the lamp board installation area 101, and the heat sinks 12 are used to dissipate heat for the lighting lamp board 11 during use, effectively preventing the problem of hidden dangers of lighting safety caused by heat accumulation. The ends of some of the heat sinks 12 extend to the connecting bridge 103; the height of the heat sink 12 located directly above the connecting bridge 103 is lower than the height of its main body, and the power supply housing 2 is placed on the heat sink 12 of this part.

[0031] like Figure 2 As shown, the lighting lamp board 11 is arranged at the inner top of the lamp board installation area 101, and its lamp board connection line passes through the lamp board installation area 101 and is electrically connected to the power supply 31 placed in the power supply housing 2; that is, the lighting lamp board 11 is powered by the power supply 31. Since the lighting lamp is arranged at the inner top of the lamp board installation area, and the heat sink 12 is arranged on the upper surface of the lamp board safety area 101, the heat sink effectively dissipates all the heat generated by the lighting lamp during the power supply process. Compared with the prior art that dissipates heat on the periphery or part of the lighting lamp, the present application has a wider heat dissipation range and a better heat dissipation effect.

[0032] like Figure 2 and Figure 3As shown, the power supply housing 2 is placed above the heat sink 12 through the power supply bracket 3, and because the power supply housing 2 is placed at the end of the heat sink 12 above the connecting bridge 103, and the end of the heat sink 12 is lower than the height of the heat sink 12 of the main body, the power supply housing 2 is spaced apart from the light source housing 1. Figure 4 As shown, a through hole 20 is formed at the top of the power housing 2 for heat output. The through hole 20 may be a circular hole, a square hole, a waist-shaped hole, or other shapes disclosed in the prior art. The shape of the through hole 20 is not limited here. The power housing is connected to the light source housing through the power bracket, which ensures the connection stability while reducing the number of bolt connections between the power housing and the light source housing. At the same time, a certain gap is ensured between the two, so that the air entering the power housing from the gap and the air entering the power housing from the through hole form convection, which is conducive to accelerating the heat dissipation of the lighting lamp.

[0033] like Figure 2 and Figure 4 As shown, the power supply bracket 3 is in a "X" shape and is centrally arranged above the light source housing 1. The top surface of the power supply bracket 3 abuts against the power supply housing 2, and the two are connected by a hanging ring 203. Furthermore, the bottom of the power supply bracket 3 is fixedly connected to the light source housing 1 by bolts; a power supply 31 is arranged on the inner side of the main body, and the connecting line of the power supply 31 passes through the top surface of the power supply housing 2 to realize the electrical connection of the power supply. The power supply is detachably connected to the inner side of the power supply bracket, and the power supply bracket provides limited space for the power supply installation position, which ensures the stability of the connection between the two and saves assembly space, thereby improving space utilization.

[0034] Further, such as Figure 2 As shown, a backup power supply 32 is detachably provided on the outer side of the power supply bracket 3. The backup power supply 32 is mounted on a backup power supply rack 321. There are two backup power supply racks 321, which are symmetrically arranged up and down, and include a connection portion that is screwed to the power supply bracket 3 and a clamping portion for sleeved with the backup power supply; a placement plane is formed at the bottom end of the clamping portion of the backup power supply rack 321 located below to limit the placement position of the backup power supply 32. By arranging a backup power supply rack on the outer side of the power supply bracket and installing a backup battery on the backup power supply rack, the installation stability of the backup battery is ensured. At the same time, the backup battery can be used for emergency lighting when the power supply is insufficient or the city power is cut off, thereby improving the practicality of the lighting lamp.

[0035] like Figure 2As shown, the side wall of the power supply bracket 3 is also provided with a dip switch 33, and the dip switch 33 is electrically connected to the lighting lamp board 11, that is, the dip switch 33 can be turned according to different lighting needs to adjust the power of the lighting lamp. Further, a waterproof plug 331 is provided on the dip switch 33, and the waterproof plug 331 can effectively prevent dew or mist from liquefying to form water droplets and dripping onto the dip switch 33, thereby affecting the normal use of the dip switch.

[0036] Further, combined with Figure 1 , Figure 2 and Figure 5 As shown, a color adjustment power supply 34 for adjusting the color temperature of the lighting lamp is also provided on the outside of the power supply bracket 3; that is, according to different needs of users or different places where the lighting lamp is used, different color temperatures of lighting can be achieved by adjusting the color adjustment power supply, thereby improving the user's comfort. The power supply housing 2 is formed with a mounting hole 201 for placing the waterproof plug 331 and the color adjustment power supply 34.

[0037] A group of through holes 30 are arranged on one side of the power supply bracket 3 away from the power supply 31. The through holes can play a role in weight reduction and increase the amount of air entering the power supply housing, further enhancing the heat dissipation effect.

[0038] A light-transmitting plate is disposed below the lighting lamp board 11. The light-transmitting plate is abutted against the bottom of the light source housing 1 through a sealing ring and is spaced apart from the lighting lamp board 11. Figure 1 The lampshade 4 is shown.

[0039] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
