Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and more specifically, to a flat panel lamp. Background Technology

[0002] Currently, planar lights, with their uniform, soft, glare-free light and high energy efficiency, are widely used in modern mainstream lighting fixtures for office, commercial, industrial, home, and medical scenarios. Their comprehensive advantages in light quality, energy consumption control, and spatial adaptability make them the preferred solution for multi-scenario lighting.

[0003] However, the inventors recognized that in practical use, the planar light has the following drawbacks: In order to facilitate user use, the driver of the planar light is set on the lamp, which leads to an increase in the thickness of the planar light. In order to avoid the driver being exposed, a protective structure is set to protect the driver, which further increases the thickness of the planar light. With the increase in the thickness of the planar light, an additional mounting layer is required during the installation process, which makes it unsuitable for installation in environments with low ceilings, resulting in a decrease in the adaptability of the planar light to the space.

[0035] This application provides a planar lamp, the specific structure of which is as follows: Figure 2-10 As shown, the planar lamp includes: a first light-emitting part 10, a frame 30 and a driving part 40. The frame 30 surrounds the first light-emitting part 10. The first light-emitting part 10 has a first side 11. The plane where the top of the frame 30 is located is higher than the plane where the first side 11 is located to form a receiving space 31. The driving part 40 is disposed in the receiving space 31 to reduce the thickness of the planar lamp in the first direction Q.

[0036] In some embodiments, such as Figure 5 As shown, where Figure 5 yes Figure 4 In the cross-sectional view along the AA direction, the plane containing the top of the frame 30 is higher than the plane containing the first side 11 to form a receiving space 31. The drive unit 40 is disposed within the receiving space 31 to reduce the thickness of the flat lamp, allowing it to be installed in low-ceilinged spaces and minimizing its obtrusive appearance after installation. Simultaneously, the frame 30 protects the drive unit 40 within the receiving space 31, reducing the impact of dust, moisture, or accidental collisions on the electronic components within the drive unit 40. Figure 2 As shown, the driving part 40 and the first light-emitting part 10 are fitted together, eliminating the need for additional external wiring space, reducing wiring complexity during installation, and lowering the risk of wiring errors.

[0037] In some embodiments, such as Figure 1 As shown, if the top of the frame 30 is flat and there is no receiving space 31, then after the drive unit 40 is installed on the top, the thickness of the flat lamp in the first direction Q is the sum of the height of the drive unit 40 and the thickness of the frame 30. If the top of the frame 30 has a receiving space 31, then the thickness of the flat lamp in the first direction is the thickness of the frame 30. Therefore, it can be seen that the flat lamp provided by this application is thinner, more suitable for installation in low spaces, and more aesthetically pleasing after installation.

[0038] In some embodiments, the planar lamp further includes: a control switch 50, which is disposed on the drive unit 40 and electrically connected to the first light-emitting unit 10 via a wire. The drive unit 40 is provided with a wire-receiving groove 41 for accommodating the wire.

[0039] In some embodiments, such as Figure 3 As shown, the control switch 50 is mounted on the drive unit 40 to avoid increasing the thickness of the planar lamp due to the additional switch base of the control switch 50. Moreover, since the drive unit 40 is the core of power control and heating, the direct connection between the control switch 50 and the drive unit 40 can shorten the distance of the wire connection and save wire usage. The drive unit 40 is provided with a wire storage groove 41 to store the wire, preventing the wire from being squeezed and rubbed, and the wire will not be exposed, thereby preventing short circuits caused by damage to the outer insulation layer of the wire, thus increasing the safety of the planar lamp.

[0040] In some embodiments, such as Figure 3 As shown, the drive unit 40 is further provided with a housing 42, which has a first side wall 421, and there is an angle between the first side wall 421 and the first side 11. The control switch 50 is disposed on the first side wall 421. The angle between the first side wall 421 and the first side 11 means that the control switch 50 is disposed on the side wall. When the flat light is installed, the top of the frame 30 fits against the mounting wall, which can avoid positional interference between the control switch 50 and the mounting wall, and can also increase the fit between the flat light and the mounting wall, thus improving the installation effect of the flat light. If the control switch 50 is disposed on a plane parallel to the drive unit 40 and the first side 11, the thickness of the drive unit 40 in the first direction Q will be increased, which will cause the flat light to not fit completely against the mounting wall, affecting the installation effect of the flat light.

[0041] The driver unit 40 provides a stable power input to the planar lamp and regulates its operating status. The driver unit 40 includes a voltage conversion component, a voltage regulator circuit, and a control component. Household electricity is typically 220V AC, while planar lamps require DC power to operate. Therefore, the driver unit 40 incorporates a voltage conversion component to convert AC to DC. Since grid voltage may fluctuate due to peak electricity consumption or circuit failures, the driver unit maintains stable output voltage and current through its built-in voltage regulator circuit, preventing the planar lamp from burning out due to sudden voltage spikes or drops. The control component adjusts the brightness and color temperature of the planar lamp. By adjusting the voltage and current, the brightness of the planar lamp is adjusted to meet lighting needs under different conditions. When adjusting the color temperature, the power supply ratio of LED chips with different color temperatures is controlled to change the color of the light, thereby improving the practicality of the lamp.

[0042] In some embodiments, the planar lamp further includes a second light-emitting part 20, which is disposed around the first light-emitting part 10. The frame 30 is provided with a mounting groove 33, and the second light-emitting part 20 is disposed within the mounting groove 33. The first light-emitting part 10 serves as the main light source, providing central direct light, while the second light-emitting part 20 is distributed around the first light-emitting part 10 and can emit side light. The superposition of the two can improve the uniformity of the planar lamp's illumination. Moreover, the second light-emitting part 20 can emit light independently and can be used as a night light, facilitating users' nighttime activities.

[0043] In some embodiments, such as Figure 6 As shown, the frame 30 is provided with a mounting groove 33, and the second light-emitting part 20 is disposed in the mounting groove 33. The mounting groove 33 can protect the second light-emitting part 20, preventing the second light-emitting part 20 from being affected by dust, water vapor or external impact. At the same time, the second light-emitting part 20 is disposed in the mounting groove 33, which can limit the displacement of the second light-emitting part 20 and increase the reliability of the fixation of the second light-emitting part 20.

[0044] In some embodiments, the frame 30 further includes a cover plate 34, which is detachably mounted on the frame 30 to cover the mounting slot 33, such as... Figure 6 As shown, the cover plate 34 is detachably installed on the mounting groove 33 to cover the mounting groove 33, thereby protecting the second light-emitting part 20 inside the mounting groove 33 and preventing dust and moisture in the air from affecting the light-emitting effect of the second light-emitting part 20.

[0045] In some embodiments, the cover plate 34 is a light-transmitting diffuse reflection cover plate, and the cover plate 34 is made of PMMA frosted material, which makes the light emitted by the second light-emitting part 20 softer and improves the uniformity of light.

[0046] In some embodiments, a first stop 331 is provided on the side wall of the mounting groove 33, and a latching member 341 that cooperates with the first stop 331 is provided on the cover plate 34. The latching member 341 is engaged with the first stop 331 along the first direction Q; specifically, as Figure 7As shown, the mounting groove 33 has a pair of opposing sidewalls, and a first stop 331 is provided on the sidewall. The first stop 331 protrudes relative to the plane of the sidewall. The cover plate 34 has a pair of snap fasteners 341. When the cover plate 34 is set on the mounting groove 33 along the first direction Q, the snap fasteners 341 and the first stop 331 snap together, so that the cover plate 34 is detachably installed on the mounting groove 33. This not only facilitates disassembly and replacement during use, but also eliminates the need for fasteners for fixation. At the same time, during the use of the plane lamp, the temperature rises. If fasteners are used for fixation, the cover plate will deform due to the temperature rise, causing the fasteners to loosen. However, by using the snap fastener method for fixation, the snap fasteners 341 adapt to temperature changes through elastic deformation, maintain a tight state, and prevent the cover plate 34 from loosening.

[0047] In some embodiments, the extending direction of the first stop 331 is consistent with the extending direction of the mounting groove 33, and the length of the first stop 331 is consistent with the length of the mounting groove 33; or, the first stop 331 may be intermittently disposed on the side wall.

[0048] In some embodiments, the extending direction of the fastener 341 is consistent with the extending direction of the cover plate 34, and the length of the fastener 341 is consistent with the length of the cover plate 34; or, the fastener 341 is intermittently disposed on the cover plate 34.

[0049] In some embodiments, the second light-emitting part 20 is provided with a plurality of lamp beads 21, which are spaced apart along the extension direction of the mounting groove 33.

[0050] like Figure 6 As shown, the second light-emitting part 20 is provided with a plurality of lamp beads 21. The lamp beads 21 are arranged at intervals along the mounting groove 33 and are arranged in a single row to avoid the light of the lamp beads 21 overlapping. Moreover, while ensuring the lighting effect, the number of lamp beads 21 used can be reduced.

[0051] In some embodiments, when the flat light is installed on a wall, the first side of the first light-emitting part 10 is close to the wall, and the lamp beads 21 emit light towards the side of the flat light and the surface close to the wall, thereby forming a hidden light-emitting effect, making the flat light more aesthetically pleasing during use.

[0052] In some embodiments, the first light-emitting portion 10 further includes a mounting plate 13, at least a portion of which abuts against the first side 11, and the mounting plate 13 is detachably mounted on the frame 30, such as... Figure 5 and Figure 6As shown, the mounting plate 13 is fixed to the frame 30 along the first direction Q, so that the mounting plate 13 can provide surface contact support for the first light-emitting part 10, thereby increasing the stability of the first light-emitting part 10 and preventing the first light-emitting part 10 from loosening and shifting position when the flat lamp is installed in a vibrating environment. At the same time, it can also prevent dust from falling on the first side 11, so as to ensure the light-emitting effect of the first light-emitting part 10. Moreover, the mounting plate 13 is a one-piece plate with strong resistance to deformation. The frame 30 is a spliced ​​structure, and the mounting plate 13 is fixed to the frame 30 on all four sides by fasteners, which can also prevent the frame 30 from loosening and deforming, thereby increasing the stability of the frame 30.

[0053] In some embodiments, the frame 30 is provided with a first step 35, which surrounds the first light-emitting part 10, and the mounting plate 13 is provided with an extension 131, which is detachably connected to the first step 35 by fasteners, such as... Figure 6 As shown, the extension 131 fits against the first step 35 along the first direction Q and is fixed by fasteners, which facilitates disassembly during maintenance.

[0054] In some embodiments, the frame 30 is further provided with a second stop 36, the first light-emitting part 10 is provided with a second side 12, the first side 11 and the second side 12 are opposite sides, the second stop 36 abuts against the second side 12, and the second stop 36 cooperates with the mounting plate 13 to restrict the movement of the first light-emitting part 10 along the first direction Q.

[0055] In some embodiments, the first side 11 of the first light-emitting portion 10 abuts against the mounting plate 13, and the mounting plate 13 is fixed to the frame 30, such as... Figure 6 and Figure 9 As shown, the second stop 36 abuts against the second side 12 of the first light-emitting part 10, and the mounting plate 13 cooperates with the second stop 36 to fix the first light-emitting part 10 on the frame 30, thereby preventing the first light-emitting part 10 from loosening and falling off.

[0056] In some embodiments, such as Figure 6 , Figure 8 and Figure 10 As shown, the first light-emitting part 10 has a first side 11 and a second side 12 that are disposed opposite to each other. That is, after assembly, the first side 11 of the first light-emitting part 10 is attached to the mounting plate 13, and the second side 12 abuts against the second stop member 36.

[0057] In some embodiments, such as Figure 8 As shown, Figure 8 The light emission angle of the central LED bead 21 is α, the distance between two adjacent LED beads 21 is d, and the value of d can be 14mm. The thickness of the cover plate 34 along the first direction Q is 1mm.

[0058] It should be understood that if the problem of dark areas formed by LED beads 21 is reduced by increasing the thickness of cover plate 34, not only will the number of LED beads 21 need to be increased, but light decay will also increase, resulting in a reduction in the utilization rate of light emitted by the second light-emitting part 20. If the number of LED beads 21 is not changed while increasing the thickness of cover plate 34, the thickness of the flat lamp in the first direction needs to be increased. Then the flat lamp will be more prominent after installation, affecting the aesthetics of the installed lamp.

[0059] Therefore, based on the above analysis, this application sets the thickness of the cover plate 34 to 1mm, and the cover plate 34 can also be covered with a diffusion film with a thickness of 0.5mm. Without the need to add additional LED beads 21, the utilization rate of the light emitted by the LED beads 21 is improved, the dark area generated when the flat light is lit is reduced, the uniformity of brightness is improved, and the thickness of the flat light can also be reduced, resulting in a better visual effect after installation.

[0060] In some embodiments, actual testing showed that the proportion of dark areas was only 15%, a significant reduction, and the light decay was only 10%.

[0061] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
