Description

Technical Field

[0001] This disclosure relates to an optical flat panel lamp, and more particularly to a multi-purpose optical flat panel lamp. Background Technology

[0002] Lighting equipment is an indispensable tool in daily life. Most existing lighting equipment uses traditional light bulbs or tubes as its light source. Among these, the most common are fluorescent tubes, tungsten filament bulbs, and halogen bulbs. Because these light sources consume a large amount of electrical energy to emit light, lighting equipment using light-emitting diodes (LEDs) as the light source has become increasingly popular in recent years. Compared with traditional light sources, LED light sources have advantages such as longer lifespan, lower power consumption, shock resistance, and higher brightness.

[0003] Flat panel lights can use LEDs as the light source. Conventionally, flat panel lights are installed in buildings using recessed or suspended methods on the ceiling. However, flat panel lights can only provide illumination of a specific color temperature in a specific direction, thus failing to cater to various usage scenarios (such as reading lighting, ambient lighting, and medical examination lighting). Therefore, how to overcome the shortcomings of conventional flat panel lights and thereby increase the lighting range, color temperature range, and application scenarios is a research topic that those skilled in the art wish to develop. Utility Model Content

[0004] According to some embodiments disclosed herein, an optical flat panel light includes a front frame, a linear lamp assembly, and a motor. The front frame has a side opening. The linear lamp assembly is located in the side opening of the front frame. The motor is connected to the linear lamp assembly.

[0005] In some embodiments, the aforementioned front frame also has a central opening, and the optical flat panel lamp further includes a flat panel lamp assembly. The flat panel lamp assembly is located in the central opening of the front frame.

[0006] In some embodiments, the aforementioned optical flat panel light also includes another linear light group and another motor. The other linear light group is located in an opening on the other side of the front frame. The central opening is located between the two side openings, and the flat panel light group is located between the two linear light groups. The other motor is connected to the other linear light group.

[0007] In some embodiments, the area of ​​the central opening of the front frame is larger than the area of ​​each of the two side openings, and the area of ​​the flat panel light group is larger than the area of ​​each of the two linear light groups.

[0008] In some implementations, the width of the aforementioned flat panel light group is greater than the width of each of the two linear light groups.

[0009] In some embodiments, the aforementioned flat panel light assembly includes a base shell, a plurality of light strips, and a diffuser plate. The base shell is located on the front frame. The light strips are located within the base shell, one of which has a color temperature of 2000K, and the other of which has a color temperature of 5700K. The diffuser plate covers the base shell and the light strips.

[0010] In some embodiments, the aforementioned flat panel light assembly also includes a wireless receiver controller. The wireless receiver controller is electrically connected to the light strip, the two-wire light assembly, and the two motors.

[0011] In some embodiments, one of the two linear lamp groups includes a plurality of first light-emitting diodes, and the other of the two linear lamp groups includes a plurality of second light-emitting diodes, wherein the color temperature of the first light-emitting diodes is different from that of the second light-emitting diodes.

[0012] In some embodiments, the color temperature of the first light-emitting diode is in the range of 1900K to 2100K, and the color temperature of the second light-emitting diode is in the range of 3900K to 4100K.

[0013] In some embodiments, the aforementioned optical flat panel light further includes a first bracket, a second bracket, and a rotating shaft. The first bracket is located on the front frame and adjacent to one end of one of the two linear lamp groups. One of the two motors is located on the first bracket. The rotating shaft of the motor passes through the first bracket and connects to that end of the two linear lamp groups. The second bracket is located on the front frame and adjacent to the other end of the two linear lamp groups. The rotating shaft passes through the second bracket and connects to the other end of the two linear lamp groups.

[0014] In the above-disclosed embodiment, since the front frame has a central opening and two side openings, and the flat panel light group is located in the central opening of the front frame, while the two linear light groups are located in the side openings of the front frame respectively, the flat panel light group is positioned between the two linear light groups. Furthermore, since the optical flat panel light has a motor connected to the linear light groups, the illumination direction of the linear light groups can be adjusted by rotating the linear light groups with the motor. In use, the flat panel light group of the optical flat panel light can be used for ambient lighting, while the two linear light groups can be used for reading lighting and medical examination lighting, respectively.

[0054] Figure 1 A plan view of an optical flat panel lamp 100 according to an embodiment of the present disclosure is shown. Figure 2 Draw Figure 1 A plan view of the front frame 110. See also... Figure 1and Figure 2 The optical flat panel light 100 includes a front frame 110, a flat panel light assembly 120, and two linear light assemblies 130a and 130b (i.e., linear light assembly 130a and another linear light assembly 130b). The front frame 110 has a central opening 112 and two side openings 114 and 116 (i.e., side opening 114 and another side opening 116), with the central opening 112 located between the two side openings 114 and 116. For example, the side opening 114 is located to the left of the central opening 112, and the side opening 116 is located to the right of the central opening 112. The front frame 110 is configured to be recessed into the ceiling to serve as a support for the flat panel light assembly 120 and the two linear light assemblies 130a and 130b. The flat panel light assembly 120 is located in the central opening 112 of the front frame 110. Linear light group 130a is located in the side opening 114 of the front frame 110, and linear light group 130b is located in the side opening 116 of the front frame 110. Thus, linear light group 130a is located to the left of the flat panel light group 120, and linear light group 130b is located to the right of the flat panel light group 120. In other words, the flat panel light group 120 is located between the two linear light groups 130a and 130b. Furthermore, the area of ​​the flat panel light group 120 is larger than the area of ​​either of the two linear light groups 130a or 130b; the larger area of ​​the flat panel light group 120 is beneficial for ambient lighting.

[0055] In this embodiment, the area of ​​the central opening 112 of the front frame 110 is larger than the area of ​​each of the two side openings 114 and 116. In addition, the width W1 of the flat panel light group 120 is larger than the width W2 of each of the two linear light groups 130a and 130b.

[0056] Figure 3 Draw Figure 1 A three-dimensional diagram of the optical flat panel lamp 100. See also... Figure 1 and Figure 3 The optical flat panel light 100 includes two motors 140a and 140b (i.e., motor 140a and another motor 140b). Motor 140a is connected to a linear lamp group 130a, and motor 140b is connected to the linear lamp group 130b. With this design, motor 140a can drive the linear lamp group 130a to rotate in direction D1 or direction D2, and motor 140b can drive the linear lamp group 130b to rotate in direction D1 or direction D2, allowing the user to conveniently and independently adjust the illumination direction of the linear lamp groups 130a and 130b. In another embodiment, the optical flat panel light 100 may have only a single motor 140a (or 140b) and a single linear lamp group 130a (or 130b).

[0057] Specifically, since the front frame 110 has a central opening 112 and two side openings 114 and 116, and the flat panel light group 120 is located in the central opening 112 of the front frame 110, while the two linear light groups 130a and 130b are located in the side openings 114 and 116 of the front frame 110 respectively, the flat panel light group 120 is positioned between the two linear light groups 130a and 130b. Furthermore, since the optical flat panel light 100 has motors 140a and 140b, and the motors 140a and 140b are connected to the linear light groups 130a and 130b respectively, the illumination direction of the linear light groups 130a and 130b can be adjusted by rotating the linear light groups 130a and 130b using the motors 140a and 140b. In use, the flat panel light group 120 of the optical flat panel light 100 can be used for ambient lighting, while the two linear light groups 130a and 130b can be used for reading lighting and medical examination lighting, respectively.

[0058] Figure 4 Draw Figure 3 Another view of the optical flat panel light 100, omitting the housing of the linear light assembly 130a. The optical flat panel light 100 also includes a first bracket 152 and a second bracket 154. The first bracket 152 and the second bracket 154 may be L-shaped. The first bracket 152 is located on the front frame 110 and adjacent to one end of the linear light assembly 130a. The motor 140a is located on the first bracket 152, for example, fixed to the vertical portion of the first bracket 152. The shaft 142 of the motor 140a can pass through the first bracket 152 and connect to the end of the linear light assembly 130a adjacent to the motor 140a. The second bracket 154 is located on the front frame 110 and adjacent to the other end of the linear light assembly 130a (i.e., the end away from the motor 140a). Another shaft 156 can pass through the second bracket 154 and connect to the end of the linear light assembly 130a away from the motor 140a. When in use, the rotating shaft 142 of the linear lamp assembly 130a can drive the linear lamp assembly 130a to rotate, and the other rotating shaft 156 can rotate with the linear lamp assembly 130a.

[0059] Furthermore, the configuration of motor 140b, linear lamp group 130b, first bracket 152 and second bracket 154 is the same as the configuration of motor 140a, linear lamp group 130a, first bracket 152 and second bracket 154 mentioned above, and will not be repeated.

[0060] Figure 5 Draw Figure 3 The bottom view of the diffuser plate 122 of the optical flat panel lamp 100 (omitted) is shown. See also... Figure 3 and Figure 5The flat panel light assembly 120 includes a base shell 124, multiple light strips 126, and a diffuser plate 122. The base shell 124 is located on the front frame 110. The light strips 126 are located within the base shell 124. The diffuser plate 122 covers the base shell 124 and the light strips 126. In this embodiment, at least one of the light strips 126 has a color temperature of 2000K, and at least another light strip 126 has a color temperature of 5700K, representing a dual-color temperature, full-spectrum design. With this configuration, the flat panel light assembly 120 can emit cool white light close to daylight quality, which can suppress melatonin during the day, improve daily focus, and is suitable for everyday ambient lighting.

[0061] Furthermore, the linear lamp assembly 130a includes a plurality of first light-emitting diodes (LEDs) 132a, and the linear lamp assembly 130b includes a plurality of second light-emitting diodes (LEDs) 132b. The first LEDs 132a and second LEDs 132b are respectively the LEDs of the linear lamp assembly 130a and the linear lamp assembly 130b, and can be housed within the aluminum extruded housing of the linear lamp assembly 130a. In this embodiment, the color temperature of the first LEDs 132a is different from that of the second LEDs 132b. The color temperature of the first LEDs 132a can be in the range of 1900K to 2100K, for example, 2000K. The color temperature of the second LEDs 132b can be in the range of 3900K to 4100K, for example, 4000K. With this configuration, the linear lamp assembly 130a can emit warm white light that eliminates the 490nm wavelength band (i.e., 490nm blue light wavelength loss), does not suppress melatonin at night, helps with relaxation and sleep, and is suitable for nighttime reading lighting. The 130b linear lamp assembly emits enhanced neutral white light in the 490nm band (i.e., 490nm blue light wavelength gain), providing the most focused light to the human body, keeping them alert and energetic, and is suitable for medical examination lighting.

[0062] The flat panel light assembly 120 also includes a wireless receiver controller 160. The wireless receiver controller 160 is electrically connected to the light strips 126, linear light groups 130a and 130b, and motors 140a and 140b of the flat panel light assembly 120. The wireless receiver controller 160 can receive wireless remote control signals over a long distance to selectively switch the flat panel light assembly 120 and the linear light groups 130a and 130b on and off. It can also dim the flat panel light assembly 120 and control the motors 140a and 140b to adjust the lighting direction of the linear light groups 130a and 130b.

Figure 1 and Figure 6A The 130a linear lamp emits warm white light that eliminates the 490nm wavelength (i.e., 490nm blue light wavelength reduction), does not suppress melatonin at night, helps relax and sleep, and is suitable for nighttime reading lighting.

[0066] Figures 7A to 7C Draw Figure 1 The optical flat panel light 100 in different usage scenarios. (See attached image) Figure 7A When user 200 needs reading lighting, the linear light group 130a can be turned on to emit warm white light that eliminates the 490nm wavelength, without suppressing melatonin, thus aiding relaxation. The flat panel light group 120 and the linear light group 130b can be turned off. See also... Figure 7B When user 200 needs ambient lighting, the flat panel light group 120 can be turned on to emit cool white light close to daylight quality, suppressing melatonin and improving daily concentration. Linear light groups 130a and 130b can be turned off. See also... Figure 7C When user 200 requires medical examination lighting, the linear light group 130b can be turned on to emit enhanced neutral white light in the 490nm wavelength band, providing the most focused light to maintain alertness and vitality. The flat panel light group 120 and the linear light group 130a can be turned off.

[0067] Figure 8 Draw Figure 1 A cross-sectional view of the diffuser plate 122 of the flat panel lamp assembly 120. The outward-facing surface of the diffuser plate 122 has a coating, such as a photocatalytic layer 123. Light L1 is the light provided by the flat panel lamp assembly 120, and light L2 is ambient light (such as light from other light sources or sunlight). When dirt 210 adheres to the photocatalytic layer 123 and is irradiated by light L1 and L2, the dirt 210 can be oxidized and decomposed (as shown in the two dirt particles 210 on the right). In addition, because the photocatalytic layer 123 is highly hydrophilic, the water film 220 used for cleaning easily adheres to the photocatalytic layer 123 and penetrates into the contact surface of the dirt 210, thereby making it easier for the dirt 210 to detach from the diffuser plate 122 (as shown in the four dirt particles 210 on the left).
