Problems solved by technology

If the existing floodlight bracket needs to be adjusted after positioning, the entire lamp body can only rotate around the bracket point at most, and the adjustment space is limited. If the installation is not in place, the bracket needs to be removed from the wall or the outer frame when it needs to be moved horizontally. It is inconvenient to re-drill and install, and it is time-consuming and labor-intensive

Embodiment 1

[0037] A floodlight, comprising a module lamp assembly consisting of one or more unit lamp bodies with erected heat sinks 141, a module lamp assembly surrounding the module lamp body assembly and detachably connected to the module lamp assembly The outer frame assembly and the bracket assembly connected to the outer frame assembly for hanging floodlights; the outer frame assembly includes a straight outer frame strip 31 with an external groove 33 on the inside, and the lower part of the bracket assembly is detachably connected to A power board 5 is arranged on the external groove of the opposite set of outer frame strips and the external groove of the other set of external frame strips. The outer shield 52 and the top shield 53 vertically connected to the inner side of the top of the outer shield. The power source 16 of the floodlight is set in the half-slot surrounded by the outer shield and the top shield. The bracket assembly includes bracket plates at both ends. And a brac...

Embodiment 2

[0042] The difference from the above embodiment is that the lower end of the bracket plate is detachably hooked to the external groove, and the bracket and the bracket plate are also connected with a bracket fixing plate 43 whose upper and lower ends are respectively connected to the bracket and the bracket plate. The bracket can slide horizontally along the bracket plate and can rotate around the connection point connected with the bracket plate. The upper end of the bracket fixing plate is hinged with the bracket, and the bottom end of the bracket plate is provided with an upper card edge 411 which is inserted upwardly into the upper half groove of the external groove and downward. The lower clip edge 412 embedded in the lower half slot of the external groove and the lower clip edge 413 located on the inner side of the lower clip edge and cooperating with the lower clip on the lower edge of the external groove, the upper groove edge is embedded in the upper clip edge and the l...

Embodiment 3

[0046] The difference from the above embodiment is that the unit lamp body includes a light-transmitting panel 11 , an optical lens 15 , a light source plate 12 , a heat sink, a power supply 16 , and at least a buckle around the edge of the unit lamp body. The pressing frame 13 on the lower surface of the radiator is integrally extruded and formed, and the radiator is formed by extrusion processing.

[0047] The edge of the unit lamp body is surrounded by a waterproof component arranged between the light-transmitting panel and the heat dissipation plate. They are staggered and arranged in a plum blossom shape, and each heat sink includes at least three heat sinks connected in a radial shape, and the heat sinks are vertically erected on the heat sink. The fins are arranged in a plum-blossom shape. When the hot air is convection, the turbulent flow can fully exchange the cold air with the heat sink, thereby taking away the heat. achieve better cooling effect. Pin-shaped struct...

Abstract

The invention belongs to the field of illuminating equipment and particularly relates to a project lamp. The project lamp comprises a modular lamp assembly, an outer frame assembly and a support assembly, wherein the modular lamp assembly is composed of one or more unit lamp bodies provided with vertically-arranged heat dissipating fins 141; the outer frame assembly surrounds the modular lamp assembly and is detachably connected with the modular lamp assembly; and the support assembly is connected to the outer frame assembly and used for hanging a project lamp on the outside. The outer frame assembly comprises straight-strip-shaped outer frame strips 31, and an external connecting profiled groove 33 is formed in the inner side of each outer frame strip 31. The lower portion of the supportassembly is detachably connected to the external connecting profiled grooves of one group of opposite outer frame strips. Power panels 5 are arranged on the external connecting profiled grooves of theother group of outer frame strips correspondingly. Each power panel comprises a folding clamp side 51, an outer side protective plate 52 arranged vertically, and a top protective plate 53 perpendicularly connected to the inner side of the top of the outer side protective plate. The upper ends of the heat dissipating fins go beyond the top protective plates. Angle ventilating passages 01 are reserved between support plates and the outer side protective plates correspondingly. The project lamp is simple in structure, low in cost, high in heat dissipating efficiency, convenient to dismount and mount and wide in application range.

Description

technical field [0001] The invention belongs to the field of lighting equipment, in particular to a floodlight. Background technique [0002] The heat sinks of the radiators of the existing floodlights are all horizontally attached to the heat sink plate, that is, the length direction of the heat sink is parallel to the plate surface, and a plurality of single-piece heat sinks are arranged in parallel. In the process of air circulation, only the wind along the length of the heat sink can smoothly enter between the heat sinks to take away the heat, the hot air convection effect is not good, and the heat dissipation effect needs to be improved. The power supply of the existing flood light is connected with the radiator and is generally located in the radiator or at one end. Since the power supply is a vulnerable part, the entire radiator needs to be disassembled to remove the power supply during maintenance and disassembly. , it is not only troublesome to assemble and connect...
