[0027] Some embodiments will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Most eye-protection lamps in related technologies emit light directly downwards. Uneven light distribution can easily cause uneven light emission across the entire lamp surface, resulting in glare and severe light that can easily damage the eyes.

[0029] In view of this, this application provides a lamp that diffuses spatial light more widely and softly, effectively reducing glare.

[0030] First, please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides a lamp 100, including a lamp frame 11, a support member 12, a first light source 13, a light diffusion module 14, and a second light source 15.

[0031] The two sides of the lamp frame 11 are connected, making the lamp frame 11 roughly ring-shaped. For example, in one embodiment of this application, the lamp frame 11 may be roughly a square ring.

[0032] The support member 12 is fixedly disposed within the lamp frame 11. The support member 12 may be an elastic material. For example, in some embodiments, the support member 12 may be a support foam.

[0033] The first light source 13 is disposed on one side of the support member 12, and the light-emitting surface of the first light source 13 faces the side away from the support member 12.

[0034] The light-diffusing module 14 is located on the side of the support member 12 away from the first light source 13. The second light source 15 is attached to the inner side of the lamp frame 11 near the light-diffusing module 14, and the second light source 15 emits light through the light-diffusing module 14 to the side away from the support member 12.

[0035] The light-diffusing module 14 is used to convert the light emitted from the second light source 15 into more uniform illumination light. For example, in some embodiments, the light-diffusing module 14 may include a reflective paper 141, a light guide plate 142, a diffusion film 143, and a prism plate 144 stacked sequentially, with the reflective paper 141 disposed on the side of the support member 12 away from the first light source 13. Understandably, in other embodiments, the light-diffusing module 14 may also include other optical components, and this application does not limit the type, number, or placement of the optical components included in the light-diffusing module 14.

[0036] In some embodiments, the first light source 13 and the second light source 15 may include LED light strips, and this application does not limit the number of light strips included in the first light source 13 and the second light source 15. Furthermore, the first light source 13 and the second light source 15 may each employ light sources with different color temperatures to create different lighting atmospheres. This application does not impose any limitations on this.

[0037] In summary, the luminaire 100 provided in this application reduces glare caused by direct light emission by placing the second light source 15 inside the lamp frame 11. Furthermore, the second light source 15 is configured to emit light evenly through the light-diffusing module 14, while the first light source 13 diffusely reflects light upwards, thus achieving uniform illumination of the luminaire 100. Additionally, this application further reduces the probability of the first light source 13 damaging the light-diffusing module 14 by providing a support member 12 between the first light source 13 and the light-diffusing module 14.

[0038] Please refer to it again. Figure 2 In some embodiments, the luminaire 100 further includes a heat sink 16 disposed between the support member 12 and the first light source 13. The heat sink 16 is used to dissipate the heat emitted by the first light source 13.

[0039] Please see Figure 3 and Figure 4 In some embodiments, the heat sink 16 may include a first heat sink 161 and a second heat sink 162 stacked together. Please continue reading. Figure 5 The first heat sink 161 is positioned close to the support member 12. A receiving groove 163 is formed on the surface of the second heat sink 162 to receive the first light source 13. Thus, the first light source 13 can contact both the first heat sink 161 and the second heat sink 162, thereby improving heat dissipation efficiency. The first heat sink 161 and the second heat sink 162 are concentrically arranged. Furthermore, the first distance from the edge of the second heat sink 162 to its center is greater than the second distance from the edge of the first heat sink 161 to its center. In other words, the projected area of ​​the second heat sink 162 in the direction perpendicular to the surface of the support member 12 covers the projected area of ​​the first heat sink 161 in the same direction.

[0040] Please refer to it again. Figure 4 In some embodiments, the lamp frame 11 includes a first blocking portion 111. One end of the first blocking portion 111 is connected to the inner wall of the lamp frame 11, and the other end of the first blocking portion 111 faces the center of the lamp frame 11. The first blocking portion 111 is used to support the light-diffusing module 14, the support member 12, and the heat sink 16. In this way, the light-diffusing module 14, the support member 12, and the heat sink 16 can be installed on the lamp frame 11.

[0041] Furthermore, the lamp frame 11 also includes a second blocking portion 112 and a third blocking portion 113. One end of the second blocking portion 112 is connected to the surface of the first blocking portion 111, and the other end of the second blocking portion 112 is connected to one end of the third blocking portion 113. The other end of the third blocking portion 113 is connected to the inner wall of the lamp frame 11. The receiving space formed by the first blocking portion 111 and the second blocking portion 112 is used to receive the light diffusion module 14, the support member 12, and the first heat sink 161, and the second light source 15 is attached to the side of the second blocking portion 112 facing the light diffusion module 14. The third blocking portion 113 and the inner wall of the lamp frame 11 form a locking groove 114. The locking groove 114 is used to engage with the edge of the second heat sink 162, thereby realizing the installation of the heat sink 16 on the lamp frame 11.

[0042] Please see Figure 5 In some embodiments, the luminaire 100 further includes a light-transmitting plate 17. The light-transmitting plate 17 is fixedly disposed on the side of the first light source 13 away from the support member 12. Understandably, the light emitted from the first light source 13 can pass through the light-transmitting plate 17, and the light-transmitting plate 17 also serves as a dustproof function. In some embodiments, the second heat sink 162 is further provided with a receiving groove 164. Thus, the edge of the light-transmitting plate 17 can slide into the receiving groove 164, so that the light-transmitting plate 17 is mounted on the heat sink 16 and covers the first light source 13.

[0043] Please refer to it again. Figure 1 In some embodiments, the luminaire 100 further includes a pressure plate 18. The pressure plate 18 is fixed above the light-transmitting plate 17, and the pressure plate 18 has fastening holes (not shown in the figure). Fasteners (such as screws) pass through the fastening holes to fix the pressure plate 18, the light-transmitting plate 17 and the heat sink 16 together.

[0044] Please continue reading. Figure 6 In some embodiments, the luminaire 100 further includes an adapter 19. The first light source 13 and the second light source 15 are electrically connected to external devices via the adapter 19. In some embodiments, the adapter 19 is provided with at least one of a radar 191 and a light sensor 192. The radar 191 is used to emit electromagnetic waves and receive the returned electromagnetic waves to detect objects around the luminaire 100. The light sensor 192 is used to collect brightness data of the environment in which the luminaire 100 is located, and the brightness data is used to adjust the brightness of the first light source 13 and / or the second light source 15.

[0045] In some embodiments, the luminaire 100 further includes a lamp post 20, a control circuit 21, and a base 22. Understandably, the lamp frame 11, support member 12, first light source 13, light diffusion module 14, second light source 15, heat sink 16, light-transmitting plate 17, pressure plate 18, and adapter 19 form a lamp head assembly. The lamp head assembly is connected to one end of the lamp post 20 via the adapter 19, and the other end of the lamp post 20 is connected to the base 30, thus enabling the luminaire 100 to be stably placed on a plane.

[0046] The control circuit 21 is at least partially disposed in the lamp post 20, and is electrically connected to the first light source 13 and the second light source 15. The control circuit 21 is used to control the operation of the first light source 13 and / or the second light source 15. Specifically, the control circuit 21 can receive data collected by the radar 191 and / or the light sensor 192, and control the lighting, extinguishing, brightness, and color temperature of the first light source 13 and the second light source 15 according to a preset program stored in the processor or memory.

[0047] Understandably, in other embodiments, the control circuit 21 may also be disposed in the lamp frame 11, and the lamp fixture 100 may also include a suspension wire assembly (not shown in the figure). Thus, the lamp head assembly can be mounted to a ceiling or other location via the suspension wire assembly without the need for the adapter 19, lamp post 20, and base 22. This application does not limit the specific installation method of the lamp fixture 100.

[0048] Please continue reading. Figure 7 In some embodiments, the control circuit 21 further includes a touch panel 211, and the touch panel 211 is provided with a plurality of touch switches. The lamp 100 can respond to the user's operation of the touch switches to realize the corresponding control of the first light source 13 and / or the second light source 15.

[0049] For example, the touch panel 211 may be equipped with a knob 2111, a display unit 2114, a first touch switch 2112, a second touch switch 2113, a third touch switch 2115, a fourth touch switch 2116, and a fifth touch switch 2117. The knob 2111, the first touch switch 2112, the second touch switch 2113, the third touch switch 2115, the fourth touch switch 2116, and the fifth touch switch 2117 can each respond to user operations and perform corresponding functions.

[0050] For example, when the user briefly presses the knob 2111 while the lamp 100 is off, the control circuit 21 controls the lamp 100 to resume the operating mode it was in before the lamp 100 was turned off, and controls the first light source 13 and the second light source 15 to maintain the brightness they were in before the lamp 100 was turned off. When the user briefly presses the knob 2111 again while the lamp 100 is on, the control circuit 21 turns off the lamp 100. When the user rotates the knob 2111 in a first direction (e.g., clockwise), the brightness of the first light source 13 and / or the second light source 15 can be increased; when the user rotates the knob 2111 in a second direction (e.g., counterclockwise), the brightness of the first light source 13 and / or the second light source 15 can be decreased. The surface of the knob 2111 is also provided with a display unit 2114 for displaying text and / or patterns to remind the user of the current brightness and / or operating mode of the lamp 100.

[0051] In some embodiments, the control circuit 21 further includes a communication unit, such as a Near Field Communication (NFC) unit. After the lamp 100 is turned on, when the user touches the first touch switch 2112, the control circuit 21 can communicate with the target device through the communication unit to receive corresponding control commands and control the lamp 100 to operate according to the corresponding control commands. The target device can be, for example, a mobile phone, a tablet computer, or a smart home control panel, etc., and this application does not limit the specific type of the target device.

[0052] After the lamp 100 is turned on, when the user briefly presses the second touch switch 2113, the control circuit 21 controls the first light source 13 to light up and controls the second light source 15 to turn off. At this time, the lamp 100 switches to home mode. In home mode, only the first light source 13 of the lamp 100 emits light, so as to reduce glare by diffuse reflection in the space where the lamp 100 is located. In home mode, when the user presses and holds the second touch switch 2113, the control circuit 21 can switch to a preset home mode according to the duration of the user's touch on the second touch switch 2113, so that the first light source 13 switches to the corresponding brightness. The preset home mode may include, for example, a natural light mode for eye protection, a relaxation mode, a soothing sleep aid mode, and a home light formula mode. Understandably, the brightness and / or color temperature of the first light source 13 may be different in different preset home modes.

[0053] After the lamp 100 is activated, when the user briefly presses the third touch switch 2115, the control circuit 21 controls the first light source 13 and the second light source 15 to illuminate. At this time, the lamp 100 switches to learning mode. In learning mode, the first light source 13 and the second light source 15 of the lamp 100 emit light simultaneously, which can meet the user's learning needs and supplement the ambient light. In learning mode, when the user presses and holds the third touch switch 2115, the control circuit 21 can switch to a preset learning mode according to the duration of the user's touch on the third touch switch 2115, so that the first light source 13 and the second light source 15 switch to the corresponding brightness. The preset learning mode may include, for example, reading and writing mode, screen viewing mode, drawing mode, learning light recipe mode, etc. Understandably, the brightness and color temperature of the first light source 13 and the second light source 15 may be different in different preset learning modes.

[0054] After the lamp 100 is activated, when the user presses the fourth touch switch 2116, the lamp 100 enters the human body sensing mode. At this time, the control circuit 21 acquires electromagnetic wave data collected by the radar 191 to detect whether there is anyone near the lamp 100, and controls the first light source 13 and the second light source 15 to work based on the detection results. For example, when the control circuit 21 detects someone within a first preset distance (e.g., 2.8 meters to 4 meters from the lamp 100), the control circuit 21 controls the first light source 13 to light up, causing the first light source 13 to diffuse and thus spread the light emitted by the first light source 13 throughout the room. When the control circuit 21 detects someone within a second preset distance (e.g., 1.6 meters from the lamp 100), the control circuit 21 controls the first light source 13 and the second light source 15 to light up. When the control circuit 21 detects that there is no one within the first and second distances for a preset duration, the control circuit 21 controls the first light source 13 and the second light source 15 to turn off, thereby achieving energy saving. When the user presses the fourth touch switch 2116 again, the lamp 100 exits the human body sensing mode.

[0055] After the lamp 100 is turned on, when the user presses the fifth touch switch 2117, the lamp 100 enters adaptive mode. At this time, the control circuit 21 acquires the brightness data collected by the light sensor 192 and stores the current brightness data. When a change in ambient light is detected, the control circuit 21 controls the brightness and color temperature of the first light source 13 and / or the second light source 15, so that the lamp 100 maintains a relatively stable brightness, thereby reducing glare. When the user presses the fifth touch switch 2117 again, the lamp 100 exits adaptive mode.

[0056] In some embodiments, the lamp post 20 is further provided with a power module to supply power to the lamp 100. The power module may include a voltage conversion circuit and / or a rechargeable battery, etc.

[0057] Furthermore, the above figures are merely illustrative of the processes included in the method according to exemplary embodiments of this application, and are not intended to be limiting.

[0058] This application is not limited to the specific embodiments described above. Those skilled in the art will readily understand that many alternative solutions exist for the test fixture without departing from the principles and scope of this application.
