Description

TECHNICAL FIELD

[0001] The disclosure relates to floodlight, in particular to a modular floodlight.BACKGROUND

[0002] Floodlights are capable of emitting high-intensity light to illuminate a target area, and therefore are widely used in various applications. For example, floodlights may be applied to various buildings, public places (such as parks and streets), and sports venues (such as football fields, basketball courts, and baseball fields).

[0003] However, currently available floodlights mainly adjust the illumination angle by rotating a bracket, and light-emitting modules thereof do not have an angle adjustment function. As a result, illumination angles and illumination ranges of currently available floodlights are significantly limited and cannot satisfy requirements of different applications.

[0004] In addition, the currently available floodlights lack an angle indication structure, and therefore a user is unable to effectively determine the current illumination angle of a floodlight. Accordingly, the currently available floodlights are inconvenient to use and fail to meet requirements of a human-oriented operational structural design.

[0005] Furthermore, due to structural limitations, the currently available floodlights are prone to angular deviation caused by external forces (such as wind or vibration)0, which results in a change in the illumination angle. As a result, the currently available floodlights may be unable to achieve the desired illumination effect under certain conditions.SUMMARY

[0006] One embodiment of the disclosure provides a modular floodlight, which includes a light-emitting module, a first side fixing frame, a first gear piece, and a second side fixing frame. The light-emitting module includes a heat sink and a light source unit disposed on one side of the heat sink. One end of the heat sink has a first gear plate. The first gear piece is fixed to the inner surface of the first side fixing frame and rotatably engaged with the first gear plate. The other end of the heat sink is rotatably fixed to the inner surface of the second side fixing frame.

[0007] In one embodiment, the first gear piece is fixed to the inner surface of the first side fixing frame by a fastening member and a spring, and the spring is disposed between the fastening member and the first gear piece.

[0008] In one embodiment, the other side of the heat sink has a plurality of heat dissipation fins.

[0009] In one embodiment, the modular floodlight further includes a driver module disposed on the heat dissipation fins.

[0010] In one embodiment, the driver module is electrically connected to the light source unit.

[0011] In one embodiment, the modular floodlight further includes an angle indication disk fixed to the other side of the heat sink. The angle indication disk has a disk body and a protruding post disposed on the disk body. The second side fixing frame has an angle indication hole. The protruding post extends through the angle indication hole, such that the other end of the heat sink is rotatably fixed to the inner surface of the second side fixing frame.

[0012] In one embodiment, the modular floodlight further includes a pressing cover disposed between the angle indication disk and the other end of the heat sink.

[0013] In one embodiment, the second side fixing frame further has an angle scale region disposed on an outer surface thereof.

[0014] In one embodiment, the angle scale region is adjacent to the angle indication hole.

[0015] In one embodiment, the modular floodlight further includes two second gear plates, a bracket, and two second gear pieces. The second gear plates are respectively fixed to the outer surface of the first side fixing frame and the outer surface of the second side fixing frame. The second gear pieces are respectively fixed to the two ends of the bracket, and the second gear pieces are respectively rotatably engaged with the second gear plates.

[0016] The modular floodlight in accordance with the embodiments of the disclosure may have the following advantages: (1) In one embodiment of the disclosure, the modular floodlight includes a light-emitting module, a first side fixing frame, a first gear piece, and a second side fixing frame. The light-emitting module includes a heat sink and a light source unit disposed on one side of the heat sink. One end of the heat sink has a first gear plate. The first gear piece is fixed to the inner surface of the first side fixing frame and rotatably engaged with the first gear plate. The other end of the heat sink is rotatably fixed to the inner surface of the second side fixing frame. As described above, the modular floodlight has a modular light-emitting module, and the light-emitting module can rotate through a specific rotational structure to adjust an illumination angle thereof. In addition, the modular floodlight further has a rotatable bracket. Accordingly, when the modular floodlight includes a plurality of light-emitting modules, the modular floodlight can achieve different illumination angles and a wider illumination range through the rotatable light-emitting modules and the bracket in order to satisfy the requirements of different applications. (2) In one embodiment of the disclosure, the heat sink of the light-emitting module of the modular floodlight is rotatably engaged with the first gear piece on the inner surface of the first side fixing frame through the first gear plate at one end thereof. The above gear-based rotatable structural design not only enables rotation of the light-emitting module, but also provides high structural stability. As a result, the modular floodlight is less likely to experience angular deviation due to external forces (such as wind or vibration). Therefore, the modular floodlight can achieve the desired illumination effect. (3) In one embodiment of the disclosure, the modular floodlight further includes an angle indication disk. The angle indication disk is fixed to the other end of the heat sink and includes a disk body and a protruding post. The protruding post is disposed on the disk body. The second side fixing frame has an angle indication hole. The protruding post passes through the angle indication hole, such that the other end of the heat sink is rotatably fixed to the inner surface of the second side fixing frame. The second side fixing frame further has an angle scale region, which is disposed on the outer surface of the second side fixing frame. The above angle indication structure allows the user to effectively determine the current illumination angle of each light-emitting module of the modular floodlight. Accordingly, the modular floodlight is highly convenient to use and meets the requirements of the human-oriented structural design. (4) In one embodiment of the disclosure, the first gear piece of the modular floodlight can be fixed to the inner surface of the first side fixing frame by a fastening member and a spring. The spring is disposed between the fastening member and the first gear piece. Accordingly, the spring force of the spring presses the first gear piece toward the first side fixing frame, so that the first gear piece is tightly abutted against the inner surface of the first side fixing frame. The above structural design can further enhance the structural stability of the gear-based rotatable structure so as to achieve the structure-reinforcing effect. (5) In one embodiment of the disclosure, the light source unit is disposed on one side of the heat sink of the modular floodlight, while the other side of the heat sink has a plurality of heat dissipation fins. Accordingly, the heat generated by the light source unit can be rapidly dissipated through the other side of the heat sink. Therefore, the heat dissipation performance of the modular floodlight can be effectively improved with a view to extending the service life of the modular floodlight. (6) In one embodiment of the disclosure, the modular floodlight has a simple design, and thus can achieve the desired functions without significantly increasing costs. Accordingly, the modular floodlight provides high practicality and conforms to future development trends.

[0020] Please refer to FIG. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5. FIG. 1 is a first perspective view of a modular floodlight according to one embodiment of the disclosure. FIG. 2 is a second perspective view of the modular floodlight according to one embodiment of the disclosure. FIG. 3 is a first exploded view of a partial structure of the modular floodlight according to one embodiment of the disclosure. FIG. 4 is a schematic view illustrating a first gear piece fixed to a first side fixing frame of the modular floodlight according to one embodiment of the disclosure. FIG. 5 is a second exploded view of a partial structure of the modular floodlight according to one embodiment of the disclosure. As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5, the modular floodlight 1 includes three light-emitting modules 11, a first side fixing frame 12, a second side fixing frame 13, three first gear pieces 14, an angle indication disk 15, a driver module 16, two second gear plates 17, a bracket 18, two second gear pieces 19, and three angle indication disks 20.

[0021] The first side fixing frame 12 and the second side fixing frame 13 are respectively disposed on the two sides of the three light-emitting modules 11.

[0022] The two second gear plates 17 are respectively fixed to the outer surface of the first side fixing frame 12 and the outer surface of the second side fixing frame 13.

[0023] The two second gear pieces 19 are respectively fixed to the two ends of the bracket 18. Accordingly, the two second gear pieces 19 are respectively rotatably engaged with the two second gear plates 17. In addition, the bracket 18 further has a hand-operated screw HS. The hand-operated screw HS passes through the second gear plate 17 and the second gear piece 19 to fix the second gear plate 17 and the second gear piece 19. The user may loosen the hand-operated screw HS and rotate the bracket 18 to an appropriate angle, and then tighten the hand-operated screw HS to prevent rotation of the bracket 18.

[0024] Each of the light-emitting modules 11 includes a heat sink 111 and a light source unit 112. The light source unit 112 is disposed on one side of the heat sink 111, and the other side of the heat sink 111 has a plurality of heat dissipation fins HF. The heat dissipation fins HF improve heat dissipation performance. One end of the heat sink 111 has a first gear plate 1111. The light source unit 112 includes a light source board LB disposed therein. In one embodiment, the light source board LB may include a circuit board and a plurality of light sources disposed on the circuit board. The light sources may be light-emitting diodes (LEDs).

[0025] The three first gear pieces 14 respectively correspond to the three heat sinks 111 (the light-emitting modules 11). The three first gear pieces 14 are fixed to the inner surface of the first side fixing frame 12. Each first gear piece 14 is rotatably engaged with the first gear plate 1111 at one end of the corresponding heat sink 111. Each first gear piece 14 is fixed to the inner surface of the first side fixing frame 12 by a fastening member Fx (such as a screw, a bolt, etc.) and a spring SP such that the spring SP is disposed between the fastening member Fx and the first gear piece 14. Accordingly, the spring force of the spring SP presses the first gear piece 14 toward the first side fixing frame 12, so that the first gear piece 14 is closely abutted against the inner surface of the first side fixing frame 12. The first side fixing frame 12 further has three locking members Fs, which respectively correspond to the three heat sinks 111 and the three first gear pieces 14 (such as screws, bolts, etc.). Each locking member Fs passes through the first gear plate 1111 of the corresponding heat sink 111 and the corresponding first gear piece 14 to fix the first gear plate 1111 and the first gear piece 14. The user may loosen the locking member Fs and rotate the light-emitting module 11 to an appropriate angle, and then tighten the locking member Fs to prevent rotation of the light-emitting module 11.

[0026] The three angle indication disks 20 respectively correspond to the three heat sinks 111 (the light-emitting modules 11). Each angle indication disk 20 is fixed to the other end of the corresponding heat sink 111 and includes a disk body 201 and a protruding post 202. The protruding post 202 is disposed on the disk body 201. The second side fixing frame 13 has an angle indication hole AH. The protruding post 202 passes through the angle indication hole AH, such that the other end of the heat sink 111 is rotatably fixed to the inner surface of the second side fixing frame 13. A pressing cover PC is further disposed between the angle indication disk 20 and the other end of the heat sink 111.

[0027] The driver module 16 is disposed on the heat dissipation fins HF of the middle heat sink 111 and is electrically connected to the light source units 112 of the light-emitting modules 11. In one embodiment, the driver module 16 may include a rectifier, a converter, a filter, and other necessary circuit components. A circuit structure of the driver module 16 is well known to those skilled in the art and therefore is not described in detail herein.

[0028] As described above, in the embodiment, the modular floodlight 1 has modular light-emitting modules 11, and the light-emitting modules 11 are rotatable through a specific rotational structure to adjust illumination angles thereof. In addition, the modular floodlight 1 further has a rotatable bracket 18. Accordingly, when the modular floodlight 1 includes a plurality of light-emitting modules 11, the modular floodlight 1 is able to achieve different illumination angles and a wider illumination range through the rotatable light-emitting modules 11 and the bracket 18 with a view to meeting the requirements of different applications.

[0029] Furthermore, in the embodiment, the heat sink 111 of each light-emitting module 11 of the modular floodlight 1 is rotatably engaged with the first gear piece 14 on the inner surface of the first side fixing frame 12 through the first gear plate 1111 at one end thereof. The gear-based rotatable structural design not only enables rotation of the light-emitting module 11, but also provides high structural stability. As a result, the modular floodlight 1 is less likely to experience angular deviation due to external forces (such as wind or vibration), and thus can achieve the desired illumination effect.

[0030] In addition, in the embodiment, each first gear piece 14 of the modular floodlight 1 is fixed to the inner surface of the first side fixing frame 12 by the fastening member Fx and the spring SP. The spring SP is disposed between the fastening member Fx and the first gear piece 14. Accordingly, the spring force urges the first gear piece 14 toward the first side fixing frame 12 so that the first gear piece 14 is tightly abutted against the inner surface of the first side fixing frame 12. The above structural design further enhances the structural stability of the gear-based rotatable structure, thereby achieving the structure-reinforcing effect.

[0031] Moreover, in the embodiment, the modular floodlight 1 has a simple design and therefore is able to achieve desired functions without significantly increasing costs. Accordingly, the modular floodlight 1 provides high practicality and conforms to future development trends.

[0032] The embodiment just exemplifies the disclosure and is not intended to limit the scope of the disclosure; any equivalent modification and variation according to the spirit of the disclosure is to be also included within the scope of the following claims and their equivalents.

[0033] Please refer to FIG. 6, which is a third perspective view of the modular floodlight according to one embodiment of the disclosure. As shown in FIG. 6, the user may loosen the hand-operated screw HS and rotate the bracket 18 to an appropriate angle, and then tighten the hand-operated screw HS to prevent rotation of the bracket 18. Similarly, the user may loosen the locking member Fs and rotate the light-emitting module 11 to an appropriate angle, and then tighten the locking member Fs to prevent rotation of the light-emitting module 11.

[0034] Accordingly, the modular floodlight 1 has modular light-emitting modules 11 that are rotatable through a specific rotational structure to adjust illumination angles thereof, and further has a rotatable bracket 18. Therefore, when the modular floodlight 1 includes a plurality of light-emitting modules 11, the modular floodlight 1 is able to achieve different illumination angles and a wider illumination range through the plurality of rotatable light-emitting modules 11 and the bracket 18, thereby satisfying requirements of different applications.

[0035] The embodiment just exemplifies the disclosure and is not intended to limit the scope of the disclosure; any equivalent modification and variation according to the spirit of the disclosure is to be also included within the scope of the following claims and their equivalents.

[0036] It is worthy to point out that the currently available floodlights mainly adjust the illumination angle by rotating a bracket, and light-emitting modules thereof do not have an angle adjustment function. As a result, illumination angles and illumination ranges of currently available floodlights are significantly limited and cannot satisfy requirements of different applications. In addition, the currently available floodlights lack an angle indication structure, and therefore a user is unable to effectively determine the current illumination angle of a floodlight. Accordingly, the currently available floodlights are inconvenient to use and fail to meet requirements of a human-oriented operational structural design. Furthermore, due to structural limitations, the currently available floodlights are prone to angular deviation caused by external forces (such as wind or vibration)0, which results in a change in the illumination angle. As a result, the currently available floodlights may be unable to achieve the desired illumination effect under certain conditions. By contrast, according to one embodiment of the disclosure, the modular floodlight includes a light-emitting module, a first side fixing frame, a first gear piece, and a second side fixing frame. The light-emitting module includes a heat sink and a light source unit disposed on one side of the heat sink. One end of the heat sink has a first gear plate. The first gear piece is fixed to the inner surface of the first side fixing frame and rotatably engaged with the first gear plate. The other end of the heat sink is rotatably fixed to the inner surface of the second side fixing frame. As described above, the modular floodlight has a modular light-emitting module, and the light-emitting module can rotate through a specific rotational structure to adjust an illumination angle thereof. In addition, the modular floodlight further has a rotatable bracket. Accordingly, when the modular floodlight includes a plurality of light-emitting modules, the modular floodlight can achieve different illumination angles and a wider illumination range through the rotatable light-emitting modules and the bracket in order to satisfy the requirements of different applications.

[0037] According to one embodiment of the disclosure, the heat sink of the light-emitting module of the modular floodlight is rotatably engaged with the first gear piece on the inner surface of the first side fixing frame through the first gear plate at one end thereof. The above gear-based rotatable structural design not only enables rotation of the light-emitting module, but also provides high structural stability. As a result, the modular floodlight is less likely to experience angular deviation due to external forces (such as wind or vibration). Therefore, the modular floodlight can achieve the desired illumination effect.

[0038] Also, according to one embodiment of the disclosure, the modular floodlight further includes an angle indication disk. The angle indication disk is fixed to the other end of the heat sink and includes a disk body and a protruding post. The protruding post is disposed on the disk body. The second side fixing frame has an angle indication hole. The protruding post passes through the angle indication hole, such that the other end of the heat sink is rotatably fixed to the inner surface of the second side fixing frame. The second side fixing frame further has an angle scale region, which is disposed on the outer surface of the second side fixing frame. The above angle indication structure allows the user to effectively determine the current illumination angle of each light-emitting module of the modular floodlight. Accordingly, the modular floodlight is highly convenient to use and meets the requirements of the human-oriented structural design.

[0039] Further, according to one embodiment of the disclosure, the first gear piece of the modular floodlight can be fixed to the inner surface of the first side fixing frame by a fastening member and a spring. The spring is disposed between the fastening member and the first gear piece. Accordingly, the spring force of the spring presses the first gear piece toward the first side fixing frame, so that the first gear piece is tightly abutted against the inner surface of the first side fixing frame. The above structural design can further enhance the structural stability of the gear-based rotatable structure so as to achieve the structure-reinforcing effect.

[0040] Moreover, according to one embodiment of the disclosure, the light source unit is disposed on one side of the heat sink of the modular floodlight, while the other side of the heat sink has a plurality of heat dissipation fins. Accordingly, the heat generated by the light source unit can be rapidly dissipated through the other side of the heat sink. Therefore, the heat dissipation performance of the modular floodlight can be effectively improved with a view to extending the service life of the modular floodlight.

[0041] Furthermore, according to one embodiment of the disclosure, the modular floodlight has a simple design, and thus can achieve the desired functions without significantly increasing costs. Accordingly, the modular floodlight provides high practicality and conforms to future development trends. As set forth above, the modular floodlight according to the embodiments can definitely achieve great technical effects.

[0042] Please refer to FIG. 7, which is a partially enlarged view of the modular floodlight according to one embodiment of the disclosure. As shown in FIG. 7, the second side fixing frame 13 further has an angle scale region SA. The angle scale region SA is disposed on the outer surface of the second side fixing frame 13. The angle scale region SA is adjacent to the angle indication hole AH. The angle scale region SA is marked with a plurality of angle scales, and the top surface of the protruding post 202 has an indication mark. Accordingly, the user is able to immediately determine the rotation angle of the light-emitting module 11.

[0043] The above angle indication structure allows the user to effectively determine the current illumination angle of each light-emitting module 11 of the modular floodlight 1. Accordingly, the modular floodlight 1 is highly convenient to use and is capable of conforming the requirements of the human-oriented structural design.

[0044] Similarly, when the modular floodlight 1 includes a plurality of light-emitting modules 11, the modular floodlight 1 is able to achieve different illumination angles and a wider illumination range through the rotatable light-emitting modules 11 and the bracket 18 in order to satisfy the requirements of different applications.

[0045] As described above, in the embodiment, the heat sink 111 of each light-emitting module 11 of the modular floodlight 1 is rotatably engaged with the first gear piece 14 on an inner surface of the first side fixing frame 12 through the first gear plate 1111 at one end thereof. The gear-based rotatable structural design not only enables rotation of the light-emitting module 11, but also provides high structural stability. As a result, the modular floodlight 1 is less likely to experience angular deviation caused by external forces (such as wind or vibration). Therefore, the modular floodlight 1 is able to achieve the desired illumination effect.

[0046] In addition, as described above, in the embodiment, each first gear piece 14 of the modular floodlight 1 is fixed to the inner surface of the first side fixing frame 12 by the fastening member Fx and the spring SP. The spring SP is disposed between the fastening member Fx and the first gear piece 14. Accordingly, the spring force of the spring SP presses the first gear piece 14 toward the first side fixing frame 12, such that the first gear piece 14 is tightly abutted against the inner surface of the first side fixing frame 12. The above structural design further enhances the structural stability of the gear-based rotatable structure, thereby achieving the structure-reinforcing effect.

[0047] Furthermore, as described above, one side of the heat sink 111 of the modular floodlight 1 is used to dispose the light source unit 112, while the other side of the heat sink 111 has a plurality of heat dissipation fins HF. Accordingly, heat generated by the light source unit 112 can be rapidly dissipated through the other side of the heat sink 111. Therefore, heat dissipation performance of the modular floodlight 1 can be effectively improved so as to extend the service life of the modular floodlight 1.

[0048] The embodiment just exemplifies the disclosure and is not intended to limit the scope of the disclosure; any equivalent modification and variation according to the spirit of the disclosure is to be also included within the scope of the following claims and their equivalents.
