Therefore, the panel light 1 can achieve high structural stability, and the safety of the panel light 1 is greatly improved.

The plurality of vertical wings 116 are disposed on the ring portion 114 and surround the opening 111 such that the plurality of vertical wings 116 surround the diffusion plate 14. In the present embodiment, the plurality of vertical fins 116 extend away from the opening 111, and an angle between the extending direction D1 of the plurality of vertical fins 116 and the diffusion plate 14 may be more than 90 °. In another embodiment, the extending direction D1 of the vertical wings 116 may have an included angle less than 90 ° with the diffusion plate 14.

A plurality of vertical wings 116 are disposed on the annular portion 114 and surround the opening 111. The light sources 13 are provided in the light source grooves 113. The diffusion plate 14 is disposed on the chassis 11 and covers the opening 111, and a plurality of vertical wings 116 surround the diffusion plate 14. Therefore, the panel light 1 is designed in a borderless structure, so that the cost of the panel light 1 can be greatly reduced, and the application range of the panel light 1 can be wider to meet the practical application requirements.

In addition, as previously described, the chassis 11 of the panel light 1 has a plurality of vertical wings 116. The plurality of vertical wing portions 116 are disposed on the annular portion 114 and surround the opening 111, so that the gap between the chassis 11 and the diffusion plate 14 can be effectively shielded. The above-mentioned structural design of the plurality of vertical wings 116 can effectively cover the gap between the chassis 11 and the diffusion plate 14, so that the appearance of the panel light 1 can be effectively optimized without adopting a frame. Thus, the panel light 1 can meet the needs of different users.

In addition, the chassis 11 and the diffusion plate 114 of the panel light 1 can be made of metal, which can greatly improve the heat dissipation effect of the panel light 1, so that the power of the panel light 1 is not limited by the heat dissipation effect.

Of course, the present embodiment is merely for illustrating the scope of the present invention, and equivalent modifications or variations of the borderless panel light with external sensor according to the present embodiment are still included in the scope of the present invention.

Please refer to fig. 4, which is a cross-sectional view of a borderless panel light with an external sensor according to an embodiment of the present invention. As shown, the chassis 11 further includes a collar portion 117 that may be disposed between the opening 111 and the annular portion 114. The convex ring portion 117 may apply an abutment force to the edge of the diffusion plate 14 to press against the edge of the diffusion plate 14, so that the diffusion plate 14 protrudes in a direction away from the opening 111 to form an arc-shaped surface. In this way, the light diffusing effect of the diffusing plate 14 having the arc-shaped surface can be effectively enhanced, so that the overall light emitting effect of the panel light 1 can be improved. In addition, the above-mentioned convex ring portion 117 can eliminate the gap between the chassis 11 and the diffusion plate 14, and make the diffusion plate 14 more stably fixed on the chassis 11, so as to prevent foreign matters (mosquitoes, dust or water) from entering the interior of the panel light 1. Therefore, the panel lamp 1 can achieve high reliability to improve the service life of the panel lamp 1. In addition, the luminous effect of the panel light 1 can be greatly optimized.

Referring to fig. 5, a second partial enlarged view of a borderless panel lamp with an external sensor according to an embodiment of the invention is shown. As shown, the annular portion 114 has a plurality of receiving grooves 1141. Each of the accommodating grooves 1141 has a hole H1 and protrudes in a direction away from the diffusion plate 14. Thus, each of the accommodating grooves 1141 may have an accommodating space. The hanging plates 115 correspond to the receiving grooves 1141, respectively. Each hanging plate 115 includes a plate body P1 and a hook P2 connected to each other. The plate body P1 of the hanging plate 115 is disposed in the corresponding accommodating groove 1141, and the hook P2 of the hanging plate 115 passes through the hole H1 of the corresponding accommodating groove 1141.

Therefore, after the plate body P1 of each hanging plate 115 is disposed in the corresponding receiving groove 1141 and the diffusion plate 14 is fixed on the ring portion 114 by the plurality of fixing members Fx, the plate body P1 of each hanging plate 115 may be limited in the space between the corresponding receiving groove 1141 and the diffusion plate 14.

By the above structural design, the hanging plates 115 can be fixed in the plurality of receiving slots 1141 without fixing members. In this way, the complexity of the manufacturing process of the panel light 1 can be effectively reduced, so that the cost of the panel light 1 is further reduced.

Referring to fig. 6, a bottom view of a chassis of a borderless panel light with an external sensor according to an embodiment of the invention is shown. As shown, the power source slot 112 and the light source slots 113 may be disposed at the bottom of the chassis 11. The light source slots 113 may be evenly distributed at the bottom of the chassis 11 and parallel to each other. The power source slot 112 may be disposed at two adjacent light source slots 113 and disposed at the center of the bottom of the chassis 11. The power module 12 is adhered to the power slot 112 by adhesive. In the present embodiment, the power module 12 may be elongated.

The power supply groove 112 and the light source grooves 113 are configured to ensure that the light sources 13 and the power supply module 12 are mounted on the chassis correctly. The built-in strip power module 12 can further beautify the appearance of the panel light 1, and ensure that the power module 12 does not affect the operation of the plurality of light sources 13.

As described above, the panel lamp 1 includes the chassis 11, the plurality of light sources 13, and the diffusion plate 14. The chassis 11 has an opening 111, a plurality of light source slots 113, an annular portion 114, and a plurality of vertical wings 116. The plurality of light source grooves 113 are provided at the bottom of the chassis 11. The annular portion 114 is provided at the periphery of the chassis 11. A plurality of vertical wings 116 are disposed on the annular portion 114 and surround the opening 111. The light sources 13 are provided in the light source grooves 113. The diffusion plate 14 is disposed on the chassis 11 and covers the opening 111, and a plurality of vertical wings 116 surround the diffusion plate 14. Therefore, the panel light 1 is designed in a borderless structure, so that the cost of the panel light 1 can be greatly reduced, and the application range of the panel light 1 can be wider to meet the practical application requirements.

Similarly, the plurality of vertical wing portions 116 are disposed on the annular portion 114 and surround the opening 111, so that the gap between the chassis 11 and the diffusion plate 14 can be effectively shielded. The above-mentioned structural design of the plurality of vertical wings 116 can effectively cover the gap between the chassis 11 and the diffusion plate 114, so that the appearance of the panel light 1 can be effectively optimized without adopting a frame. Thus, the panel light 1 can meet the needs of different users.

The chassis 11 of the panel light 1 further comprises a collar portion 117 arranged between the opening 111 and the annular portion 114. The convex ring portion 117 presses against the diffusion plate 14, so that the diffusion plate 14 protrudes away from the opening 111 to form an arc surface, thereby improving the illumination effect of the panel light 1. In addition, the above-mentioned convex ring portion 117 can eliminate the gap between the chassis 11 and the diffusion plate 14, and make the diffusion plate 14 more stably fixed on the chassis 11, so as to prevent foreign matters from entering the interior of the panel light 1. Therefore, the panel light 1 can achieve high reliability, and the service life and the light emitting effect of the panel light 1 can be improved.

Please refer to fig. 7, which is a perspective view of a borderless panel light with an external sensor according to another embodiment of the present invention, and please refer to fig. 2. As shown in the figure, unlike the foregoing embodiment, the panel light 1 of the present embodiment further includes a sensor expansion module 15 and a sensor 16. The sensor expansion module 15 is disposed in the chassis 11 and connected to the power module 12 (shown in fig. 2). The sensor 16 is disposed on the diffusion plate 14 and connected to the sensor expansion module 15. In this embodiment, the sensor 16 may be an infrared sensor (PRI sensor). In an embodiment, the sensor 16 may be a microwave sensor, a light sensor, or other similar component. In one embodiment, the sensor expansion module 15 may include signal conversion circuitry that may convert the sensed signal into an electrical signal to control the power module 12. The circuit structure and function of the sensor expansion module 15 should be well known to those skilled in the art, and thus will not be described in detail herein.

Please refer to fig. 8 and 9, which are a first enlarged partial view and a second enlarged partial view of a borderless panel lamp with an external sensor according to another embodiment of the present invention. As shown, the diffusion plate 14 has a sensor interface SP, which is connected to the sensor expansion module 15, and the sensor 16 is detachably inserted into the sensor interface SP. In this embodiment, the sensor interface SP may be a three-wire interface. The sensor interface SP is a hollow cylindrical structure with a central core, and may include a first pole X1, a second pole X2, a third pole X3, a plastic isolation region PZ, and a threaded region SZ. The cylinder body of the hollow cylinder structure is a first pole X1, the annular part of the top surface of the hollow cylinder structure is a second pole X2, and the central core wire of the hollow cylinder structure is a third pole X3. The plastic isolation region PZ is disposed between the first pole X1 and the second pole X2 to isolate the first pole X1 from the second pole X2, and the threaded region SZ is disposed at the bottom of the first pole X1. The first pole X1 may be an anode, the second pole X2 may be a cathode, the third pole X3 may be a signal line, and the functions of the first pole X1, the second pole X2 and the third pole X3 may be changed according to actual needs, which is not limited in the present invention. The connection terminals of the sensor 16 have a structure corresponding to the three-wire interface described above.

Through the structural design of the three-wire interface, a user can install the sensor 16 or replace the sensor 16 quickly and conveniently by himself without assistance of technicians.

In addition, the cylindrical integration structure of the three-wire interface integrates the first pole X1 and the second pole X2 with a hollow cylinder body, and a central core wire arranged in the center of the hollow cylinder body is used as the third pole X3, so that the first pole X1, the second pole X2 and the third pole X3 are properly integrated in the cylindrical integration structure. Therefore, the cylindrical integrated structure has a foolproof function, so as to ensure that a user can correctly install the sensor 16.

In addition, the three-wire interface structure has provided the first pole X1, the second pole X2 and the third pole X3, which can be the positive pole, the negative pole and the signal line, respectively, so the signal line does not need to be shared with the positive pole and the negative pole (the signal line of the conventional 3.5 earphone interface needs to be shared with the positive pole and the negative pole).

Furthermore, the three-wire interface structure has a threaded region SZ, so that the sensor 16 is not easy to fall off, and the stability of the overall structure is improved. In another embodiment, the sensor interface SP may also be a USB interface or other various existing interfaces.

Through the above-mentioned external sensor design, the sensor 16 can be detachably mounted on the diffusion plate 14 and connected with the sensor expansion module 15, without requiring an additional sensor base. Therefore, the external sensor design can greatly reduce the complexity and cost of the sensor 16, and can meet the practical application requirements.

The diffusion plate 14 has a sensor interface SP, and the sensor interface SP is connected to the sensor expansion module, and the sensor 16 is inserted into the sensor interface SP. Therefore, with the hot plug design described above, a user can install or replace the sensor 16 by himself without the assistance of a technician. Therefore, the panel light 1 is more convenient to use.

It should be noted that the sensor of the existing panel light needs to be installed on the frame of the panel light. However, the above-described installation often requires a technician to make sure that the sensor is functioning properly, which adds to the complexity and cost of the installation. Since the sensor needs to be mounted on the bezel of the panel light, an additional mounting of the sensor mount is required and the wire connection is typically required through the structure of the panel light. In addition, this mounting is also susceptible to limitations of the structure of the panel light, resulting in further increases in complexity and cost of the mounting. In contrast, according to an embodiment of the present invention, a panel light includes a chassis, a plurality of light sources, a diffusion plate, a power module, a sensor expansion module, and a sensor. The chassis has an opening. The plurality of light sources are arranged in the chassis. The diffusion plate is arranged on the chassis and covers the opening, and the diffusion plate is surrounded by a plurality of vertical wing parts. The power module is arranged in the chassis and is electrically connected with the plurality of light sources. The sensor expansion module is arranged in the chassis and is connected with the power supply module. The sensor is arranged on the diffusion plate and connected with the sensor expansion module. Through the design of the external sensor, the sensor can be detachably arranged on the diffusion plate and is connected with the sensor expansion module, and an additional sensor base is not needed. Therefore, the design of the external sensor can greatly reduce the complexity and cost of the sensor installation, and can meet the requirements of practical application.
