In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figures 1 to 5As shown, the utility model provides a lighting module 100 and a floodlight. The floodlight includes a support 200 and at least two lighting modules 100 . The lighting modules 100 are spliced ​​into a preset shape, and all lighting modules 100 are fixed on the support 200 .

[0042] The lighting module 100 includes a base 10, a cover plate 40, a reflector 20 and an anti-glare assembly. The cover plate 40 is covered on the base 10 and encloses the base 10 to form a cavity. The cover plate 40 is provided with an opening connected to the cavity.

[0043] In this embodiment, the floodlight includes four lighting modules 100, each of which has a fan-shaped cross section. The four lighting modules 100 are fixed to the support 200 and spliced ​​into a preset shape, which is a circular ring. In other embodiments, the preset shape can also be set to a rectangular or other shape; the cross section of the lighting module 100 can also be a semicircular shape; the shapes of different lighting modules 100 in the same floodlight can also be different.

[0044] By setting the reflector 20 to converge and form parallel light, ensuring the light output quality is conducive to uniform lighting, and a rotatable anti-glare tube 50 is set at the opening of the cover plate 40. The anti-glare tube 50 can block the light-emitting element 14 and the reflector 20 from the surrounding side to prevent the light from directly entering the human eye and causing glare when looking up at the reflector 20 or the light-emitting element 14; the anti-glare tube 50 rotates to achieve focused glare control in a specific area, effectively solving the glare problem; according to the lighting requirements of different positions, different numbers of light-emitting elements 14 are set in different lighting modules 100, so as to ensure the uniformity of ground lighting.

[0045] Specifically, the base 10 further includes a bracket 11 and a power source 12, and the power source 12 and the light-emitting element 14 are respectively arranged on both sides of the bracket 11; the base 10 further includes a heat sink 13, and the heat sink 13 is arranged between the light-emitting element 14 and the bracket 11. By arranging the power source 12 and the light-emitting element 14 on both sides of the bracket 11, the structure is compact and the occupied space is saved; by arranging the heat sink 13 between the light-emitting element 14 and the bracket 11, the heat generated by the power source 12 during the power supply process can be transferred to the heat sink 13 through the bracket 11, and the heat of the light-emitting element 14 can also be conducted through the heat sink 13 and dissipated to the surrounding environment; by arranging the heat sink 13, the heat dissipation area is increased, the heat dissipation effect is improved, and it is helpful to increase the service life of the lighting module 100.

[0046] Preferably, the heat sink 13 is made of a heat-conducting material; the heat sink 13 has a plurality of heat sinks, and the heat sinks are made of aluminum sheets or copper sheets; the light-emitting element 14 is attached to the heat sink 13; and the power source 12 can be a rectifier power source or a battery.

[0047] In this embodiment, the lighting module 100 is connected to the support member 200 through the bracket 11; the light-emitting member 14 includes a substrate and a lamp bead, and the lamp bead is arranged on the side of the substrate away from the heat sink 13; the reflector 20 is arranged on the substrate of the light-emitting member 14, and the reflector 20 is a cylindrical shape with openings at both ends. The reflector 20 is sleeved on the outside of the lamp bead, and the lamp bead is located at the center of the reflector 20, and the reflector 20 and the lamp bead are arranged one by one.

[0048] Preferably, the light emitting element 14 is an LED light board (Light Emitting Diode). The LED light board has the advantages of energy saving, environmental protection, rich colors and long service life. It is understandable that the reflector 20 can be set according to the existing technology, such as a metal reflective cup, which will not be described in detail here.

[0049] like Figures 5 to 7 As shown, the lighting module 100 further includes a light-transmitting cover 30, which is covered on the base 10, located between the cover plate 40 and the base 10, and is covered outside the reflector 20. By arranging the light-transmitting cover 30 outside the reflector 20, the light-transmitting cover 30 can shield and protect the reflector 20 and the lamp beads, and prevent dust and foreign matter from falling on the reflector 20 or the lamp beads, which affects the normal use of the lighting module 100. In this embodiment, the light-transmitting cover 30 of the lighting module 100 is covered on the base plate, and all the reflectors 20 and the lamp beads are covered therein; the light-transmitting cover 30 is made of a transparent material.

[0050] Preferably, the lighting module 100 further includes a waterproof member 70. The light-transmitting cover 30 is provided with a mounting groove. The waterproof member 70 is disposed in the mounting groove. The waterproof member 70 is pressed between the light-transmitting cover 30 and the substrate of the light-emitting member 14. The waterproof member 70 is provided to seal the gap between the light-transmitting cover 30 and the light-emitting member 14, so that the waterproof function is provided to prevent water from entering through the gap and affecting the normal use of the light-emitting member 14.

[0051] For ease of installation, the cover plate 40 is covered on the outside of the light-transmitting cover 30 and the edge of the cover plate 40 is located above the edge of the light-transmitting cover 30. The cover plate 40, the light-transmitting cover 30 and the radiator 13 are all fixed by a locking piece 80; the cross-sections of the light-transmitting cover 30, the radiator 13 and the cover plate 40 are all fan-shaped; the locking piece 80 is a bolt or a screw.

[0052] Specifically, the opening of the cover plate 40 and the reflector 20 are arranged on both sides of the light-transmitting cover 30, the opening and the reflector 20 are arranged one-to-one correspondingly, and the anti-glare tube 50 and the opening are arranged one-to-one correspondingly, so that the light emitted by each lamp bead is reflected by the reflector 20 and then emitted from the anti-glare tube 50 at the opening, and each lamp bead controls glare through a separate anti-glare tube 50.

[0053] Furthermore, the anti-glare tube 50 includes a connecting section and a shielding section. The connecting section is rotatably disposed in the cavity. The shielding section is connected to the connecting section. The shielding section extends from the opening and is used to shield the light-emitting member 14 from the peripheral side.

[0054] Preferably, the outer surface of the connecting section is in an arc shape with a high middle and a low edge, and the shielding section is in a cylindrical shape; the anti-glare tube 50 is made of a black material, and the inner surface of the anti-glare tube 50 is a matte surface. By providing a black anti-glare tube 50, part of the light can be absorbed, and the inner surface is set to a matte surface to prevent the light from being reflected on the inner surface of the anti-glare tube 50.

[0055] In this embodiment, the opening of the cover plate 40 is circular, the maximum outer diameter of the connecting section is larger than the opening diameter, the connecting section is clamped inside the cavity, the outer diameter of the shielding section is smaller than the opening diameter, and the shielding section extends from the opening; the opening diameter is larger than the maximum inner diameter of the reflector 20.

[0056] In order to enable the anti-glare tube 50 to rotate, the anti-glare assembly further includes a fixing ring 60, which is partially sleeved on the end of the connecting section of the anti-glare tube 50, and the connecting section of the anti-glare tube 50 presses the fixing ring 60 against the inner wall of the cover plate 40 along the circumferential direction. By providing the fixing ring 60, the anti-glare tube 50 can be fixed after rotating an angle, preventing the anti-glare tube 50 from loosening during use.

[0057] In this embodiment, the fixing ring 60 is located above the light-transmitting cover 30 and inside the cavity; the fixing ring 60 is made of silicone material; the fixing ring 60 is cylindrical, and the edge of one end of the fixing ring 60 extends radially outward to form an annular protrusion, which fits the light-transmitting cover 30 to increase the contact area and ensure the stability of the setting of the fixing ring 60.

[0058] The specific lighting process of the lighting module 100 is as follows:

[0059] The light from the light emitting element 14 is reflected and converged by the inner wall of the reflector 20 to form parallel light, which propagates and vertically enters the light-transmitting cover 30. The light maintains the original direction and passes through the light-transmitting cover 30. The light passes through the fixing ring 60 and the anti-glare tube 50 and is emitted from the shielding section of the anti-glare tube 50 to achieve lighting.

[0060] The angle between the line from the outermost point of the inner wall edge of the reflector 20 to the light-emitting edge of the anti-glare tube 50 and the horizontal line passing through the center of the light bead of the lighting module 100 is the shielding angle θ, and the range of the shielding angle θ is 30° to 50°. When the human eye looks up from the side of the lighting module 100 (that is, the line of sight is within the range of the shielding angle θ), the shielding section of the anti-glare tube 50 can shield the light-emitting element 14 and the reflector 20, so that the human eye will not look directly at the light-emitting element 14 and the inner wall of the reflector 20, thereby effectively controlling glare.

[0061] In the same floodlight, the number of light-emitting elements 14 in different lighting modules 100 can be set according to the lighting requirements of different positions. The anti-glare tubes 50 in the same lighting module 100 can be set at the same or different angles, and the anti-glare tubes 50 in different lighting modules 100 can be set at the same or different angles, thereby effectively controlling glare while ensuring the uniformity of ground lighting. Each lighting module 100 can be controlled individually, and a lighting module 100 can also be used alone. It has a large lighting range and a wide range of applications. It has a modular design and flexible assembly to adapt to various practical application scenarios.

[0062] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
