[0078] In this embodiment, combined with Figure 7-10 The rotating assembly adopts a hinge assembly 04, and the hinge assembly 04 includes a first hinge body 0402, a second hinge body 0404, a torsion spring 0403 and a rotating shaft 0401; one end of the first hinge body 0402 is installed on the electrical cavity upper cover 09, and one end of the second hinge body 0404 is installed on the electrical cavity lower shell part 032; the other end of the second hinge body 0404 is rotatably connected with the other end of the first hinge 302 through the rotating shaft 0401, and the torsion spring 0403 is sleeved on the rotating shaft 0401.

[0079] In this embodiment, a torsion spring is added to the hinge assembly 04, so that the electrical cavity upper cover 09 can be opened under the action of the torsion spring elastic force after being unlocked. At the same time, under the support of the torsion spring, the electrical cavity upper cover 09 will not endanger the construction safety during installation and maintenance because the lamp cover is closed by gravity; in addition, the setting of the support rod is omitted, so that the opening and closing of the lamp cover is convenient.

[0080] In this embodiment, the first hinge body 0402 can be integrally formed on the electrical cavity upper cover 09, or can be installed on the electrical cavity upper cover 09 through a connecting piece; the second hinge body 0404 can be integrally formed on the electrical cavity lower shell part 032, or can be installed on the electrical cavity lower shell part 032 through a connecting piece, and there is no limitation here.

[0081] In this embodiment, the first hinge body 0402 includes a "U"-shaped portion and a connecting portion; the connecting portion is perpendicular to one side of the "U"-shaped portion, and the connecting portion is used to connect with the electrical cavity upper cover 09; specifically, two first connecting holes 0405 are provided on the connecting portion, and the first hinge body 0402 is installed on the electrical cavity upper cover 09 through the first connecting holes 0405 with a connecting member 041, wherein the connecting member 041 can be implemented by a screw or other structure, which is not limited here.

It is preferred to have two first mounting hole structures 0406 and two second mounting hole structures 0407 to ensure the stability of the connection.

[0083] Furthermore, the second hinge body 0404 is mounted on the lower housing portion 032 of the electrical cavity, and the end of the "U"-shaped upper cover 08 is just covered on the second hinge body 0404; the first hinge body 0402 is mounted on the back of the electrical cavity upper cover 09; this embodiment has the following advantages through the above structural definition:

[0084] 1. After the electrical cavity cover 09 is closed, the hinge components are all located inside the housing and are invisible, thus ensuring the beautiful appearance of the lamp;

[0085] 2. Combined with the design of the "U"-shaped portion, after the first hinge body 0402 rotates a certain angle, the bottom of the "U"-shaped portion abuts against the end of the "U"-shaped upper cover 08, such as Figure 8 As shown in , the opening angle of the electrical cavity upper cover 09 is limited, and the shedding of the surface coating due to the hard contact between the electrical cavity upper cover 09 and the "U"-shaped upper cover 08 with an unlimited structure is avoided.

[0086] Furthermore, at least one second connection hole is provided on the second hinge body 0404, and the second hinge body 0404 is equipped with a second connection member and installed on the lower housing part 032 of the electrical cavity through the second connection hole. The second connection member is implemented by a screw or the like, which is not limited here.

[0087] In this embodiment, combined with Figure 7 and Fig.14 The locking assembly 07 includes a hook structure 0701 disposed on the electrical cavity upper cover 09 and a sliding buckle structure 0702 disposed on the electrical cavity lower housing portion 032 .

[0089] Reference Fig.14 When the electrical cavity upper cover 09 is closed, the sliding buckle structure 0702 is aligned with the through hole 092, and the hook structure 0701 pushes the sliding buckle structure 0702 to move leftward along the slide rail structure 0703 through the inclined surface at the end; the electrical cavity upper cover 09 continues to be pressed down to close, and the sliding buckle structure 0702 passes through the through hole 092, and the hook structure 0701 hooks on the sliding buckle structure 0702, and the connection between the hook structure 0701 and the sliding buckle structure 0702 is also provided with a protrusion structure designed to prevent the sliding buckle structure 0702 from sliding left and right naturally, thereby preventing the buckle structure from falling off naturally. When it is necessary to open the electrical cavity upper cover 09, just push the sliding buckle structure 0702 to the left with force to separate it from the hook structure 0701.

[0090] The locking assembly 07 provided in this embodiment can realize the opening and locking of the electrical cavity upper cover 09 without the aid of any tools, thereby improving the efficiency and convenience of lamp assembly and maintenance.

[0091] In this embodiment, a sealing structure is provided between the electrical cavity upper cover 09 and the electrical cavity.

[0092] Specific, combined Figure 7 , 11 , 12, 13, the sealing structure includes a sealing rib 0321 protruding on a circle of the electrical cavity, a sealing ring 010 sleeved on the sealing rib 0321, and a sealing groove 091 provided at a position corresponding to the sealing rib 0321 on the electrical cavity upper cover 09; the electrical cavity upper cover 09 is provided on the electrical cavity, the sealing rib 0321 extends into the sealing groove 091, and the sealing ring 010 is pressed between the sealing rib 0321 and the sealing groove 091. The sealing structure of the electrical cavity provided in this embodiment achieves sealing by extending the sealing rib into the sealing groove and then pressing the sealing ring tightly against the sealing groove and the sealing rib. Compared with the prior art method of achieving sealing only by the sealing ring, this sealing method has a higher sealing effect.

[0093] Further, combined with Figure 12-13 The sealing ring 010 is U-shaped, and a groove 0101 is formed on the upper circle. The sealing ring 010 is sleeved on the sealing rib 0321 through the groove 0101. A sealing tongue 0102 protruding into the groove is provided on one side wall of the groove 0101; when the electrical cavity upper cover 09 is closed, the sealing rib 0321 drives the sealing ring 010 to be clamped into the sealing groove 091, and the inner side wall of the sealing groove 091 squeezes the outer side wall of the sealing ring, and the sealing tongue 0102 is squeezed between the inner side wall of the sealing groove 091 and the sealing rib 0321, and the sealing tongue 0102 is deformed, thereby achieving the sealing of the electrical cavity.

[0094] Furthermore, the thickness of the side wall of the sealing tongue 0102 of the sealing ring 010 gradually increases from one side of the bottom of the slot 0101 to the other side, so that the side sealing effect is further enhanced by this design.

[0095] Furthermore, a gap 092 is left between the bottom of the sealing groove 091 and the top of the sealing ring 010, so that after the electrical cavity upper cover 09 is closed, the sealing ring 010 is only deformed on the left and right sides for sealing; there is no contact between the top of the sealing ring 010 and the electrical cavity upper cover 09, thereby reducing the resistance caused by the sealing in the form of deformation of the top of the sealing ring when the upper cover is closed (the lamp cover and the top of the sealing ring are squeezed and deformed), making the upper cover open and close smoother; the sealing ring 010 of this embodiment adopts side sealing, which also avoids the sealing failure caused by the deformation of the upper cover or the sealing ring fixing rib when the sealing ring 010 adopts the top deformation sealing form.

[0096] In this embodiment, combined with Figure 15-25 The LED module 01 includes a heat sink 10, a light-emitting component and a lens component covering the light-emitting component are arranged on the front of the heat sink 10, and at least one electrical hole 1001 is arranged on the back of the heat sink 10, and an electrical connection male connector 6 is arranged in the electrical hole, and the electrical connection male connector 6 is also electrically connected to the light-emitting component.

[0097] The LED module provided by the present invention is directly inserted into the electrical hole 1001 through the electrical connection female head 12 (in this process, the electrical connection female head 12 and the electrical connection male head 6 are electrically connected at the same time), and at the same time realizes the structural fixation and electrical connection functions of the LED module, which greatly simplifies the LED module structure, is simple to assemble, and is easy to maintain.

[0098] In this embodiment, two electrical holes 1001 are provided on the back of the heat sink 10, and two electrical connection female heads 12 are correspondingly provided on the back cover 13, and the two electrical connection female heads 12 correspond to the two electrical holes 1001 one by one. In this embodiment, two sets of electrical connection structures (two electrical holes 1001 and two electrical connection female heads 12) are provided on the back of the heat sink 10. On the one hand, the arrangement of the two sets of electrical connection structures is conducive to ensuring the stability of the connection of the LED module. On the other hand, when multiple LED modules are installed in the whole lamp, they are convenient to be connected in series with the LED modules on the left and right sides. The electrical connection heads between the specific connected LED modules are directly connected in series through wires. Of course, in other embodiments, only one or more than two sets of electrical connection structures may be provided on the heat sink 10, which can be selected according to specific needs and are not limited here.

[0099] In this embodiment, the electrical connection male connector 6 includes at least one electrical connection male pin 602, and the electrical connection female connector 12 includes at least one electrical connection female pin 1201 matching the electrical connection male pin 602.

[0100] Furthermore, the electrical connection male pin 602 and the electrical connection female pin 1201 are connected by a butt-plug type connection, that is, the electrical connection male pin 602 is inserted into the socket of the electrical connection female pin 1201 to achieve electrical connection; this embodiment adopts a butt-plug type electrical connection method, which further facilitates the disassembly and maintenance of the LED module, and also plays a role in strengthening the structural connection of the LED module to a certain extent. Of course, in other embodiments, other electrical connection methods such as contact type can also be used between the first connector and the second connector, which is not limited here and can be adjusted according to specific needs.

[0101] Further, such as Figure 3 As shown in the figure, the electrical connector 6 also includes a plastic part 601, two electrical connector pins 602 are mounted on the plastic part 601, the plastic part 601 is placed in the electrical hole 1001, and the outer ring of the plastic part 601 is positioned with the inner ring of the electrical hole 1001 by means of a buckle or other structure, and the upper end of the electrical connector pin 602 extends to the front of the heat sink 1 to be electrically connected to the light-emitting component. The arrangement of the plastic part 601 in this embodiment has the following functions: (1) the plastic part 601 fixes the two electrical connector pins 602 together to prevent the pins from being deflected and affecting subsequent insertion; (2) the plastic part 601 cooperates with the inner wall of the electrical hole 1001 to ensure that the pins will not be offset as a whole.

[0102] In this embodiment, combined with Fig. 22 , 23 , 25, at least one circle of O-ring 14 is sleeved on the outer ring of the electrical connector female 12, and the O-ring 14 is inserted into the electrical hole 1001 along with the electrical connector female 12, and has an interference fit with the electrical hole 1001, so as to realize a tight connection between the electrical connector female 12 and the electrical hole 1001. Further, a sealing gasket 15 is sleeved on the outer ring of the electrical connector female 12, and after the electrical connector female 12 is inserted into the electrical hole 1001, the sealing gasket 15 is tightly pressed between the end surface of the electrical hole 1001 and the electrical connector female 12.

[0103] In this embodiment, two circles of O-rings 14 are arranged on the electrical connector 12; specifically, a mounting groove is arranged on the electrical connector 12, and the O-ring 14 is clamped in the mounting groove to achieve fixed installation between the O-ring 14 and the electrical connector 12. Of course, in other embodiments, the number of O-rings 14 can be adjusted according to specific circumstances, and is not limited here.

[0104] This embodiment, through the provision of multiple O-rings 14, on the one hand, realizes the structural fixed installation of the LED module through interference fit, and also realizes the waterproof and dustproof functions; and through the provision of the sealing gasket 15, the sealing effect of the connection is further strengthened, and the reliability of dustproof and waterproof is achieved through three-layer protection.

[0105] The LED module provided in this embodiment can achieve the three functions of structural connection, electrical connection and sealing by one-time plug-in installation, omitting the process of connecting wires and reducing the links of the sealing structure, and is simple to assemble and easy to maintain.

[0106] In this embodiment, the light-emitting component includes an LED light source 9, a light source pressure plate 8 and an electrical board 5; the LED light source 9 is arranged on the front side of the heat sink 1; the light source pressure plate 8 is annular, pressed on a circle of the LED light source 9 and connected to the heat sink 10, and the light source pressure plate 8 is electrically connected to the LED light source 9; the electrical board 5 is also annular, arranged around the light source pressure plate 8, and one end of the electrical connection male pin 602 passes through the heat sink 10 and is electrically connected to the electrical board 5; the electrical board 5 is electrically connected to the light source pressure plate 8.

[0107] The LED module provided by the present invention directly realizes the electrical connection between the LED light source 9 and the electrical connection male pin 602 through the light source pressure plate 8 and the electrical board 5. The entire LED module does not use any wires, has a simple structure, and is easy to disassemble and assemble, which is convenient for the maintenance and replacement of the LED light source 9. At the same time, the annular light source pressure plate 8, the electrical board 5 and their arrangement make the entire light-emitting component compact in structure, which is conducive to reducing the size.

[0108] In this embodiment, combined with Figure 4 , the LED light source 9 is arranged in the middle of the front side of the radiator 10, the electrical board 5 is arranged in the outer circle of the LED light source, the light source pressing plate 8 is arranged between the LED light source 9 and the electrical board 5, and pressed on the outer circle of the LED light source 9, and the light source pressing plate 8 is fixed to the radiator 10 by means of screws or the like, and the fixed installation of the LED light source 9 is also realized at the same time. This installation method has a simple and compact structure; of course, in other embodiments, the installation method of the LED light source 9, the light source pressing plate 8 and the electrical board 5 can also be adjusted according to specific needs, which is not limited here.

[0109] In this embodiment, welding holes are provided at positions on the electrical board 5 corresponding to the electrical connection male pins 602, and each electrical connection male pin 602 corresponds to a welding hole; in this embodiment, two groups of welding holes are provided on the electrical board 5, and each group has two welding holes; the upper ends of the electrical connection male pins 602 are passed through the welding holes and welded together with the welding holes, thereby realizing the electrical connection between the electrical connection male pins 602 and the electrical board 5. This connection method completely omits the use of wires and greatly simplifies the structure.

[0110] In this embodiment, at least one conductive spring 802 is disposed on the inner circle of the light source pressing plate 8, and the conductive spring 802 is pressed on the conductive electrode of the LED light source 9, thereby realizing the electrical connection between the conductive spring 802 and the LED light source 9. The number of the conductive springs 802 is consistent with the number of groups of the electrical connection male pins 602, and two conductive springs 802 are disposed on the inner circle of the light source pressing plate 8 in this embodiment.

[0111] Furthermore, the light-emitting component also includes a light source pressure plate pin 7; one end of the light source pressure plate pin 7 is inserted into the light source pressure plate 8 and contacts the conductive spring sheet 802 to realize electrical connection, and the other end of the light source pressure plate pin 7 extends out of the light source pressure plate 8 and is welded together with the circuit on the electrical board 5, thereby realizing the electrical connection between the electrical board 5 and the conductive spring sheet 802, and then realizing the electrical connection between the electrical connection male pin 602 and the LED light source 9. The electrical connection male pin 602, the electrical board 5, the light source pressure plate pin 7, the conductive spring sheet 802, and the LED light source 9 sequentially form a conductive path.

[0112] According to the above, the two welding holes corresponding to the same group of electrical connection male pins 602 are respectively connected to the two welding holes corresponding to the other group of electrical connection male pins 602 through the first circuit a and the second circuit b on the electrical board 5, thereby realizing the electrical connection between the two electrical connection male pins 6021 and 6022 of the same group and the other group of electrical connection male pins 6023 and 6024. Further, the power supply ends of the LED light source are respectively connected to the first circuit a and the second circuit b through two conductive springs and two light source pressure plate pins 7, thereby forming Figure 7 The power supply circuit shown in the figure does not use any cables, which greatly simplifies the internal structure of the LED module.

[0113] The light-emitting assembly provided in this embodiment has a compact conductive structure and does not require the use of wires; furthermore, the LED light source and the light source pressure plate 8 are directly electrically connected by means of springs without the need for welding, thereby greatly facilitating the maintenance and replacement of the LED light source.

[0114] Among them, the number of light source pressure plate pins 7 is set with reference to the number of groups of electrical connection male pins 602; in this embodiment, two light source pressure plate pins 7 are set, and the two light source pressure plate pins 7 are symmetrically arranged on the side wall of the light source pressure plate 8. The welding positions of the two light source pressure plate pins 7 and the electrical board 5 are respectively located between the two groups of welding holes, such as Figure 6 as shown in .

[0115] In this embodiment, a socket 801 is further provided on the light source pressure plate 8 at a position corresponding to each light source pressure plate pin. One end of the socket 801 extends to the conductive spring sheet 802 , and the other end extends to the outer edge of the light source pressure plate 8 . The light source pressure plate pin 7 is inserted into the socket 801 .

[0116] In this embodiment, the LED light source 9 can be realized by a structure such as an LED light bead, which is not limited here.

[0117] In this embodiment, the lens assembly includes a lens 2 and an anti-glare ring 1; the lens 2 is covered on the light-emitting assembly, the anti-glare ring 1 is pressed on a circle of the lens 2 and is fixedly connected to the heat sink 10 through structures such as screws 11.

[0118] Among them, the main function of the anti-glare ring 1 is to control the light output angle of the non-main light on both sides of the lens, so that less light is projected into the human eyes, thereby achieving the purpose of anti-glare. In this embodiment, the anti-glare ring 1 is detachably mounted on the radiator. When in use, the anti-glare ring 1 of different heights can be replaced to adjust the light distribution type of the LED module. Specifically, due to the height of the anti-glare ring: anti-glare ring A < anti-glare ring B < anti-glare ring C, the corresponding light output angle: anti-glare ring A (x°) > anti-glare ring B (y°) > anti-glare ring C (z°), so it can be seen that the higher the anti-glare ring, the smaller the light output angle and the stronger the light control ability. The present invention can achieve the purpose of changing the light distribution type of the lamp by controlling the light output angle of the lamp. For example, anti-glare rings of different heights can be assembled to achieve the conversion of the lamp between the cut-off light type and the half-cut-off light type to meet the needs of more working environments.

[0119] In this embodiment, the lens assembly further includes a reflector 4, which is arranged between the lens 2 and the light-emitting assembly; the reflector 4 is annular, arranged around the LED light source 9 and covering the light source pressure plate 8 and the electrical board 5. In this embodiment, the reflector 4 is arranged to shield the light source pressure plate 8 and the electrical board 5, which has a certain aesthetic effect.

[0120] In this embodiment, the lens assembly further includes a sealing ring 3, which is tightly pressed between the lens 2 and the heat sink 10 to achieve a sealing effect, thereby achieving the waterproof and dustproof function of the light-emitting assembly.

[0121] In this embodiment, combined with Figure 2-3 A plurality of heat dissipation fins are arranged on the back of the radiator 10, and transverse convection holes 1005 are arranged at the connection between the heat dissipation fins and the radiator 10. Vertical convection holes 1004 that penetrate the radiator 10 are also arranged at positions corresponding to the transverse convection holes 1005 on the radiator 10, and the vertical convection holes 1004 are connected with the transverse convection holes 1005.

[0122] In this embodiment, through the corresponding transverse convection holes and longitudinal convection holes are arranged at the positions below the heat sink. The cold air passes through the vertical convection holes and the transverse convection holes in sequence and then directly flows through the surface of the heat sink fins, so that the cold air is in full contact with the heat sink fins and takes away the heat on the heat sink fins. The arrangement of the transverse convection holes and the longitudinal convection holes accelerates the convection of the air. Compared with the solution in the prior art that only dissipates heat through the surface of the heat sink fins, the present invention can take away more and faster heat from the heat sink ribs, thereby ensuring the reliability of the heat dissipation of the lamp and the stability of its operation.

[0123] Furthermore, the heat dissipation fins include a plurality of radial heat dissipation fins 1002 arranged circumferentially around the center of the back side of the radiator 10, and a circumferential heat dissipation fin 1003 connecting the outer ends of two adjacent radial heat dissipation fins 1002. In this embodiment, by jointly setting the radial heat dissipation fins 1002 and the circumferential heat dissipation fins 1003, on the one hand, the heat dissipation area is increased, and on the other hand, together with the vertical convection holes 1004 and the horizontal convection holes 1005, a chimney-type heat dissipation channel is formed, which is conducive to improving the heat dissipation effect. Of course, in other embodiments, the specific structural form of the heat dissipation fins can also be adjusted according to specific needs, which is not limited here.

[0124] Furthermore, the transverse convection holes 1005 are arranged at the connection between the circumferential heat dissipation fins 1003 and the radiator 10. The cold air moving upward in the vertical convection holes is divided into two parts after passing through the transverse convection holes, flowing through the outer side of the circumferential heat dissipation fins 1003 and the inner side of the circumferential heat dissipation fins 1003 respectively, so that the cold air is fully in contact with the heat dissipation fins, thereby improving the heat dissipation efficiency. The outer side of the heat dissipation fins and the inner wall of the rear cover 5 form a circular chimney-type heat dissipation channel, and the air flowing through the outer side of the heat dissipation fins is accelerated and flows through quickly. The air flowing through the inner side of the heat dissipation fins also takes away the heat on the radial heat dissipation fins 1002, making the heat dissipation more sufficient.

[0125] In this embodiment, the LED module further includes a rear cover 13, and the LED module is installed at the target position through the rear cover.

[0126] Specifically, the rear cover 13 includes a rear cover bottom and a surrounding wall arranged around the rear cover bottom, and the LED module is installed on the mounting hole 1302 on the rear cover bottom through a connecting piece. The connecting piece can be a structure such as a screw. After the LED module is connected to the rear cover 13 by inserting the electrical connector 12 into the electrical hole 1001, it can only ensure that the module will not fall off due to gravity, but does not achieve the locking function. The LED module in this embodiment further achieves locking and fixing of the LED module through the setting of the connecting piece.

[0127] In this embodiment, the electrical connector 12 is also fixedly mounted on the bottom of the rear cover by means of screws or other structures.

[0128] In this embodiment, the distances between the two electrical holes 1001 and the center of the back side of the heat sink 10 are not equal.

[0129] Specifically, refer to Fig.10 , the distances "x" and "y" between the two electrical connectors A and B fixed on the back cover 13 and the center of the back cover are different, that is, x≠y; the distances "u" and "v" between the two electrical holes A and B on the radiator 10 and the center of the module are different, that is, u≠v; but the distance "x" between the electrical connector A and the center of the back cover is equal to the distance "u" between the electrical hole A on the radiator and the center of the module, that is, x=u; the distance "y" between the electrical connector B and the center of the back cover is equal to the distance "v" between the electrical hole B on the radiator and the center of the module, that is, y=v.

[0130] Furthermore, four positioning feet 1304 are provided on the wall of the rear cover 13, and matching positioning notches 1006 are provided at corresponding positions on the back of the radiator 10.

[0131] When the LED module is assembled with the back cover 13, the positioning pins 1304 on the back cover 13 cooperate with the positioning notches 1006 on the heat sink 10 to ensure that the two are assembled concentrically without deflection or twisting. When the electrical hole A on the LED module is assembled with the electrical connector A in opposite directions, because the distance between the two from the center is the same u=x, the electrical connector A can be smoothly inserted into the electrical hole A on the module, and the module can be assembled with the back cover. When the electrical hole A on the LED module is assembled with the electrical connector B in opposite directions, because the distance between the two from the center is different u≠y, the electrical connector B cannot be inserted into the electrical hole A on the module, and the LED module cannot be assembled with the back cover.

[0132] From the above, it can be seen that the assembly between the LED module and the back cover 13 is mainly achieved by the different distances between the electrical connectors and the electrical holes on both sides to achieve the anti-fool effect. When the distance between the center and the size of the two is consistent, the assembly is smooth, and when the distance between the center and the size of the two is inconsistent, the assembly cannot be performed.

[0133] This foolproof structure is completed by using the existing functional structure of the LED module and the back cover, without adding any extra structure. The functions of the foolproof structure are: ① The module will not malfunction due to reverse installation of the LED module; ② The assembly efficiency is improved during module production and assembly; ③ When repairing the lamp, the maintenance personnel do not need to identify the module assembly direction, and only the module with the correct direction can be assembled.

[0134] Those skilled in the art will appreciate that the present invention can be implemented in many other specific forms without departing from the spirit or scope of the present invention. Although embodiments of the present invention have been described, it should be understood that the present invention should not be limited to these embodiments, and those skilled in the art can make changes and modifications within the spirit and scope of the present invention as defined by the appended claims.
