Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, and more specifically, to a floodlight for ports. Background Art

[0002] A floodlight is a lamp with a higher illumination on the designated illuminated surface than the surrounding environment. It is also called a spotlight. Usually, it can be aimed in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-area work sites and mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights.

[0003] Floodlights are mainly composed of three parts: optical components, mechanical components and electrical components. The optical components are mainly reflectors and shading grids that limit light. The mechanical components are mainly shells, as well as focusing mechanisms that fix and adjust the position of the light source, brackets and bases that fix the lamps, and parts with angle indicators that adjust the projection direction of the lamp beam. The shell is connected to the bracket by opening screw holes on the shell and fixing the shell to the bracket with bolts. However, this connection method makes it easy for the screw holes to be damaged after multiple adjustments to the projection direction of the lamp beam, making it impossible to fix the shell. In addition, the pressure of the lamp is mostly concentrated on the screw holes, which further damages the screw holes and reduces the service life of the lamp. Replacing the shell increases the cost of replacement, which is not conducive to the promotion of the lamp. Utility Model Content

[0036] A floodlight for a port, such as Figure 1 As shown, it includes a base 1 and a light-emitting component 2. The base 1 is used as a mounting base. A connecting shaft 4 is detachably connected to the base 1. A stopper for fixing the position of the light-emitting component 2 is provided. The light-emitting component 2 is used to emit light. A connecting hole for inserting the connecting shaft 4 is provided on the light-emitting component 2. The light-emitting component 2 can swing around the axis of the connecting shaft 4. After the light-emitting component 2 adjusts the angle of the emitted light, the stopper fixes the position of the light-emitting component 2.

[0037] The connection between the light emitting component 2 and the base 1 is achieved by drilling a hole in the light emitting component 2, passing the connecting shaft 4 through the connecting hole, and fixing the connecting shaft 4 with a stopper. No tapping screw is provided in the connecting hole, thereby avoiding the situation where the screw hole in the existing floodlight is damaged, thereby increasing the service life of the lamp and reducing the cost of the lamp.

[0038] In this embodiment, the base 1 is a concave frame structure, the limiting member is a bolt 3, and an anti-slip gasket 6 is provided on the bolt 3.

[0039] Specifically, Figure 1 , Figure 2 As shown, the light-emitting assembly 2 includes a connecting frame 21, a heat sink 22 and a light-emitting member 23. The connecting hole is provided on the connecting frame 21, and a limiting hole 211 for inserting a limiting member is provided on the connecting frame 21. The heat sink 22 is installed on the connecting frame 21, and the light-emitting member 23 is arranged on the heat sink 22. After the heat sink 22, the light-emitting member 23 and the connecting frame 21 are assembled to form the light-emitting assembly 2, the connecting shaft 4 passes through the connecting hole, the light-emitting assembly 2 is installed on the base 1, the heat sink 22 is rotated, and the heat sink 22 drives the light-emitting member 23 to rotate around the axis of the connecting shaft 4, and the angle of the light beam emitted by the light-emitting member 23 is adjusted. After the angle of the light beam emitted by the light-emitting member 23 is determined, the limiting member is inserted into the limiting hole 211 to fix the position of the light-emitting member 23.

[0040] In this embodiment, the light emitting element 23 is an LED bulb.

[0041] Further, such as Figure 2As shown, a connection hole is also provided on the heat sink 22. When fixing the light-emitting component 2, the connection shaft 4 also passes through the connection hole on the heat sink 22, thereby increasing the contact area between the light-emitting component 23 and the connection shaft 4, reducing the pressure on the light-emitting component 2, and further improving the life of the light-emitting component 2.

[0042] Preferably, the radiator 22 adopts a hollow design to increase contact with air and improve the heat dissipation effect.

[0043] Further, such as Figure 2 , Figure 3 As shown, an anti-glare frame 221 is also provided on the heat sink 22 , and the anti-glare frame 221 is provided around the light-emitting element 23 to achieve an anti-glare effect.

[0044] Preferably, the height of the anti-glare frame 221 is higher than the height of the light-emitting element 23 , so as to achieve an anti-glare effect and prevent the light-emitting element 23 from being hit, thereby protecting the light-emitting element 23 .

[0045] Preferably, two connection frames 21 are provided and are installed at two opposite ends of the heat sink 22 to improve the stability of fixing the heat sink 22 .

[0046] Preferably, if Figure 4 As shown, a plurality of limiting holes 211 are provided, and the plurality of limiting holes 211 are evenly distributed along the center of the connecting hole, so as to facilitate adjustment and fixation of the angle of the light beam emitted by the light emitting member 23 .

[0047] Further, such as Figure 4 As shown, a through hole 11 is opened on the base 1, and the connecting shaft 4 passes through the through hole 11. Screws cooperating with nuts 5 are arranged at both ends of the connecting shaft 4. The nuts 5 cooperate with the screws to fix the connecting shaft 4 on the base 1, which is convenient for replacing the connecting shaft 4 and assembling the lamp group.

[0048] Preferably, if Figure 5 As shown, an anti-skid gasket 6 is provided between the nut 5 and the base 1 to strengthen the connection effect between the nut 5 and the screw and prevent the nut 5 from falling off.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
