Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically to a lighting fixture. Background Technology

[0002] In related technologies, ceiling lights are the main lighting fixtures in homes. With the improvement of living standards, families have higher and higher requirements for the overall thickness of the lamps. The thinner the lamp body, the less space and ceiling height it occupies, and the better the aesthetics. However, most ceiling lights with ambient lighting on the market at present are relatively thick direct-light emission solutions. Utility Model Content

[0003] The present invention aims to at least solve or improve the technical problem of excessive thickness of lamps in the prior art.

[0004] Therefore, some embodiments of this utility model propose a lamp.

[0005] In view of the above, according to some embodiments of the present invention, the present invention proposes a lamp, comprising: a frame; a first light source assembly disposed on the inner sidewall of the frame; a light guide assembly disposed on the frame and disposed opposite to the first light source assembly; a back plate disposed on the frame and separated from the light guide assembly; and a driver disposed between the light guide assembly and the back plate, wherein the driver and the first light source assembly are electrically connected; wherein the first light source assembly includes a circuit, at least a portion of which is located on the side of the light guide assembly facing the driver.

[0006] The lamp proposed in this utility model includes a frame, a first light source assembly, a light guide assembly, a back plate, and a driver. The first light source assembly, the light guide assembly, and the back plate are disposed on the frame, which forms a ring structure. The first light source assembly is disposed on the inner side wall of the frame. The light guide assembly and the back plate are disposed approximately parallel to each other and opposite to each other. The driver is disposed between the light guide assembly and the back plate and is electrically connected to the first light source assembly. Thus, the driver can drive the first light source assembly to emit light, and the light guide assembly guides the light emitted by the first light source assembly, thereby realizing the illumination of the lamp. Furthermore, the back plate can enclose the frame to protect the components inside the frame and can also provide a certain reflective effect, thereby improving the brightness of the lamp.

[0007] The first light source component includes a circuit, at least a portion of which is located on the side of the light guide component facing the driver. This allows at least a portion of the circuit to be placed within the space of the driver. Since the driver itself is always present, placing at least a portion of the circuit on the side of the light guide component facing the driver does not increase the thickness of the luminaire. Furthermore, this arrangement reduces the thickness of the circuit below the light guide component, thereby reducing the overall thickness of the luminaire.

[0008] In some embodiments, the circuit may optionally include an LED bead line forming a path, a first line, a wire, and a second line, the first line being located on the side of the LED bead line facing the back panel, and at least a portion of the second line being located on the side of the LED bead line facing the back panel. In the case where the second line is present between the LED bead line and the first line, the LED bead line is connected to the first line via a wire, the wire crossing the second line.

[0009] In this embodiment, the circuit includes an LED bead circuit, a first circuit, a wire, and a second circuit. The LED bead circuit, the first circuit, the wire, and the second circuit form a circuit and are electrically connected to the driver. The driver can drive the first light source component.

[0010] Furthermore, the first line is located on the side of the LED bead line facing the back panel, and at least part of the second line is located on the side of the LED bead line facing the back panel. With the second line between the LED bead line and the first line, the LED bead line is connected to the first line through a wire, and the wire passes over the second line, thereby reducing the line of the LED bead line facing away from the back panel. This helps to reduce the size of the first light source assembly along the direction from the light guide assembly to the back panel, thereby achieving the purpose of reducing the thickness of the lamp.

[0011] In some embodiments, the number of LED chip circuits may be at least one, the number of second circuits may be one, and the LED chip circuits, the first circuit, the wires and the second circuit form a path.

[0012] In this embodiment, there are one or more LED chip circuits and one second circuit. The LED chip circuit, the first circuit, the wire, and the second circuit form a path. That is, all the LED chip circuits form a path through the same first and second circuits, thereby ensuring that the second circuit is not arranged on the side of the LED chip circuit away from the back plate. This reduces the size of the first light source assembly along the direction from the light guide assembly to the back plate, thereby achieving the purpose of reducing the thickness of the lamp.

[0013] In some embodiments, the number of LED bead circuits may be multiple, the number of second circuits may be multiple, and the LED bead circuits, first circuits, wires and second circuits form multiple pathways.

[0014] In this embodiment, there are multiple LED bead circuits and multiple second circuits. The LED bead circuits, first circuits, wires, and second circuits form multiple paths. That is, all LED bead circuits are connected through the same first circuit and different second circuits, thereby realizing the arrangement of multiple LED bead circuits and the arrangement of LED bead circuits with different color temperatures in the lamp, thus improving the functionality of the lamp.

[0015] In some embodiments, the luminaire may optionally further include a second light source assembly disposed on the side of the frame opposite to the first light source assembly, the second light source assembly being electrically connected to the driver.

[0016] In this embodiment, the luminaire also includes a second light source component disposed on the frame. The second light source component is located on the outside of the frame, that is, on the side of the frame away from the first light source component. The second light source component is electrically connected to a driver, which can drive the second light source component to emit light, thereby increasing the number of light sources in the luminaire, providing multiple light emission modes, and increasing the functionality of the luminaire.

[0017] In some embodiments, optionally, the outer side of the frame has a receiving cavity, and the second light source assembly is disposed within the receiving cavity.

[0018] In this embodiment, the outer side of the frame has a receiving cavity, and the second light source assembly is disposed in the receiving cavity, thereby protecting the second light source assembly with the frame and reducing the space occupied by the lamp.

[0019] In some embodiments, the frame may optionally include: a frame body on which the first light source assembly, the light guide assembly, and the back plate are all disposed; and a first protruding edge located at one end of the frame body, the first protruding edge being disposed side by side with the back plate, the first protruding edge protruding from the back plate.

[0020] In this embodiment, the frame includes a frame body and a first protruding edge. The first light source assembly, the light guide assembly, and the back plate are all disposed on the frame body. The first protruding edge is disposed at one end of the frame body. The first protruding edge and the back plate are arranged side by side. Furthermore, the first protruding edge protrudes beyond the back plate, that is, the back plate is lower than the end of the first protruding edge, thereby achieving a frame body fits the mounting surface and reducing the installation gap of the lamp.

[0021] In some embodiments, the luminaire may optionally further include a fastener for securing the backplate to the frame, wherein a first protrusion protrudes from the fastener.

[0022] In this embodiment, the lamp also includes a fastener for fixing the back plate. The fastener passes through the back plate and is fixed to the frame, thereby fixing the back plate and the frame. Furthermore, the first protrusion protrudes from the fastener, that is, the fastener is lower than the end of the first protrusion, thereby making the frame fit the mounting surface and reducing the installation gap of the lamp.

[0023] In some embodiments, the frame may optionally include a second protruding edge disposed on the inner side of the frame, and the light guide assembly is mounted on the second protruding edge.

[0024] In this embodiment, the frame also includes a second protruding edge disposed on the inner side of the frame, and the light guide assembly is mounted on the second protruding edge, thereby reducing the installation difficulty of the lamp and facilitating the assembly of the lamp.

[0025] In some embodiments, the luminaire may optionally include a support member disposed between the light guide assembly and the backplate.

[0026] In this embodiment, the luminaire also includes a support member disposed between the light guide assembly and the back plate, thereby supporting the light guide assembly and the back plate and ensuring the stability of the light guide assembly.

Detailed Implementation

[0038] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] The following reference Figures 1 to 7 To describe a lamp 100 provided according to some embodiments of the present invention.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, according to some embodiments of the present invention, the present invention provides a lamp 100, which can be a ceiling lamp, wall lamp, table lamp, or floor lamp, etc.

[0042] The luminaire 100 includes a frame 110, a first light source assembly 120, a light guide assembly 140, a back plate 150, and a driver 160. The first light source assembly 120, the light guide assembly 140, and the back plate 150 are disposed on the frame 110. The driver 160 is located inside the frame 110 and between the light guide assembly 140 and the back plate 150.

[0043] The frame 112 has a ring-shaped structure. The inner side of the frame 112 is used to install the first light source assembly 120, the light guide assembly 140, the back plate 150, and the driver 160. The first light source assembly 120 is disposed on the inner sidewall 1122 of the frame 112, which is also a ring-shaped structure. The first light source assembly 120 can be a ring-shaped structure or a plate-shaped structure. Multiple plate-shaped first light source assemblies 120 are disposed alternately on the inner sidewall 1122. For example, two first light source assemblies 120 are disposed opposite each other on both sides of the inner sidewall 1122. The first light source assembly 120 can cover the entire inner sidewall 1122 or it can not cover the entire inner sidewall 1122, that is, it covers part of the inner sidewall 1122.

[0044] Optionally, the dimensions of the first light source assembly 120 and the inner sidewall 1122 can be the same along the direction from the back plate 150 to the light guide, thereby helping to reduce the thickness of the frame 110.

[0045] Alternatively, the back panel 150 can block the entire inner space of the frame 110, or it can cover part of the inner space.

[0046] The first light source assembly 120 includes a circuit 122, at least a portion of which is located on the side of the light guide assembly 140 facing the driver 160.

[0047] The lamp 100 provided by this utility model includes a frame 110, a first light source assembly 120, a light guide assembly 140, a back plate 150, and a driver 160. The first light source assembly 120, the light guide assembly 140, and the back plate 150 are disposed on the frame 110, which forms a ring structure. The first light source assembly 120 is disposed on the inner sidewall 1122 of the frame 110. The light guide assembly 140 and the back plate 150 are arranged substantially parallel to each other. The driver 160 is disposed between the light guide assembly 140 and the back plate 150. The driver 160 is electrically connected to the first light source assembly 120, so that the driver 160 can drive the first light source assembly 120 to emit light. The light guide assembly 140 guides the light emitted by the first light source assembly 120, thereby realizing the illumination of the lamp 100. In addition, the back plate 150 can close the frame 112 to protect the components inside the frame 112, and can also play a certain reflective role, thereby improving the brightness of the lamp 100.

[0048] The first light source assembly 120 includes a circuit 122, at least a portion of which is located on the side of the light guide assembly 140 facing the driver 160. This utilizes the space of the driver 160 to place at least a portion of the circuit 122. Since the driver 160 is inherently present, placing at least a portion of the circuit 122 on the side of the light guide assembly 140 facing the driver 160 does not increase the thickness of the lamp 100. Furthermore, this arrangement reduces the thickness of the circuit 122 below the light guide assembly 140, thereby reducing the overall thickness of the lamp 100.

[0049] In related technologies, the LEDs are usually placed on the side of the light guide plate facing the driver, resulting in the stacking of the light guide plate, driver, and LEDs, which leads to a thicker luminaire.

[0050] like Figure 4As shown, in some embodiments, optionally, circuit 122 includes LED chip circuit 124, first circuit 126, wire 128, and second circuit 130. The number of LED chip circuits 124 and second circuits 130 can be at least one. LED chip circuit 124, first circuit 126, wire 128, and second circuit 130 form at least one path. The first circuit 126 is located on the side of LED chip circuit 124 facing the backplate 150, and at least a portion of the second circuit 130 is located on the side of LED chip circuit 124 facing the backplate 150. When the second circuit 130 is present between LED chip circuit 124 and first circuit 126, LED chip circuit 124 is connected to the first circuit 126 via wire 128, which crosses the second circuit 130. One of the first circuit 126 and the second circuit 130 is a positive terminal, and the other is a negative terminal.

[0051] In this embodiment, the circuit 122 includes an LED bead circuit 124, a first circuit 126, a wire 128, and a second circuit 130. The LED bead circuit 124, the first circuit 126, the wire 128, and the second circuit 130 form a circuit and are electrically connected to the driver 160. The driver 160 can drive the first light source assembly 120.

[0052] Furthermore, the first line 126 is located on the side of the lamp bead line 124 facing the back plate 150, and at least a portion of the second line 130 is located on the side of the lamp bead line 124 facing the back plate 150. With the second line 130 between the lamp bead line 124 and the first line 126, the lamp bead line 124 is connected to the first line 126 by a wire 128. The wire 128 crosses the second line 130, thereby reducing the line of the lamp bead line 124 on the side away from the back plate 150. This is beneficial for reducing the size of the first light source assembly 120 along the direction from the light guide assembly 140 to the back plate 150, thereby achieving the purpose of reducing the thickness of the lamp 100.

[0053] In this process, the space on the side of the LED bead circuit 124 facing the back plate 150 depends on the thickness of the driver 160, while the space on the side of the LED bead circuit 124 away from the back plate 150 depends on the routing of the circuit 122 on the side of the LED bead circuit 124 away from the back plate 150. The fewer the routing of the circuit 122 on the side of the LED bead circuit 124 away from the back plate 150, the smaller the size of the entire first light source assembly 120. The first light source assembly 120 uses wires 128 to arrange the first line 126 on the side of the LED bead circuit 124 facing the back plate 150. Since the space occupied by the driver 160 is significantly larger than the space on the side of the LED bead circuit 124 away from the back plate 150, the wires 128 are also located above the LED bead circuit 124. Through the above wiring arrangement, the number of LED bead circuits on the side of the LED bead circuit 124 away from the back plate 150 is reduced, thereby reducing the thickness of the first light source assembly 120, the thickness of the frame 110, and the thickness of the lamp 100.

[0054] The LED circuit 124 includes at least one light-emitting diode, which is connected in series.

[0055] The first light source assembly 120 also includes a lamp board 132, and the circuit 122 is disposed on the lamp board 132. That is, the lamp bead circuit 124, the first circuit 126, the wire 128 and the second circuit 130 are all disposed on the lamp board 132.

[0056] like Figure 4 As shown, in some embodiments, optionally, the number of LED bead lines 124 is at least one, and the number of second lines 130 is one. The LED bead lines 124, the first line 126, the wire 128, and the second line 130 form a path. One of the first line 126 and the second line 130 is a positive line, and the other is a negative line. The first line 126 is located above the LED bead lines 124, and at least a portion of the second line 130 is located above the LED bead lines 124. One LED bead line 124 is directly connected to the first line 126 and directly connected to the second line 130. This allows other LED bead lines 124 to have a second line 130 between them and the first line 126. Furthermore, other LED bead lines 124 are connected to the first line 126 via the wire 128, and other LED bead lines 124 are directly connected to the second line 130. The wire 128 can cross the second line 130 to connect to the first line 126.

[0057] In this embodiment, there are one or more LED bead lines 124 and one second line 130. The LED bead lines 124, the first line 126, the wire 128, and the second line 130 form a path. That is, all the LED bead lines 124 form a path through the same first line 126 and second line 130, thereby ensuring that the second line 130 is not arranged on the side of the LED bead lines 124 away from the back plate 150, thereby reducing the size of the first light source assembly 120 along the direction from the light guide assembly 140 to the back plate 150, thereby achieving the purpose of reducing the thickness of the lamp 100.

[0058] Among them, multiple LED bead circuits 124 are connected in parallel.

[0059] like Figure 5As shown, in some embodiments, optionally, there are multiple LED bead lines 124 and multiple second lines 130, forming multiple pathways with the LED bead lines 124, first lines 126, wires 128, and second lines 130. The LED bead lines 124 can be divided into multiple groups, and there are multiple second lines 130. A group of LED bead lines 124 connects to the same second line 130, and different groups of LED bead lines 124 connect to different second lines 130. Each group of LED bead lines 124 can have different characteristics, such as light intensity, color temperature, or power.

[0060] In this embodiment, there are multiple LED bead circuits 124 and multiple second circuits 130. The LED bead circuits 124, the first circuit 126, the wires 128, and the second circuits 130 form multiple paths. That is, all the LED bead circuits 124 are connected through the same first circuit 126 and different second circuits 130, thereby realizing the arrangement of multiple LED bead circuits 124 and the arrangement of LED bead circuits 124 with different color temperatures within the lamp 100, thus improving the functionality of the lamp 100.

[0061] Among them, multiple LED bead circuits 124 are connected in parallel.

[0062] Taking the first line 126 as the positive line and the second line 130 as the negative line as an example, there is one first line 126 and two second lines 130, namely the second line 130A and the second line 130B. The LED bead lines 124 are divided into two groups, namely LED bead lines 124A and LED bead lines 124B. The first line 126 and the second line 130A are located above the LED bead lines 124, and the second line 130B is located below the LED bead lines 124. One LED bead line 124A is directly connected to the first line 126 and directly connected to the second line 130. This allows the other LED bead lines 124 to have the second line 130A between them and the first line 126. Furthermore, the other LED bead lines 124A are connected to the first line 126 by the wire 128, and the other LED bead lines 124 are directly connected to the second line 130A. The wire 128 can cross the second line 130A to connect to the first line 126. One LED circuit 124B is directly connected to the first circuit 126 and directly connected to the second circuit 130B. However, other LED circuits 124B and the first circuit 126 are connected by a second circuit 130A. Furthermore, other LED circuits 124B are connected to the first circuit 126 via a wire 128. Other LED circuits 124B are directly connected to the second circuit 130B. The wire 128 can cross the second circuit 130A and connect to the first circuit 126.

[0063] like Figure 3 , Figure 6 and Figure 7As shown, in some embodiments, the luminaire 100 may optionally include a second light source assembly 170 disposed on a frame 110, the second light source assembly 170 being disposed on the side of the frame 110 opposite to the first light source assembly 120, and the second light source assembly 170 being electrically connected to the driver 160.

[0064] In this embodiment, the lamp 100 further includes a second light source assembly 170 disposed on the frame 110. The second light source assembly 170 is located on the outside of the frame 110, that is, on the side of the frame 110 away from the first light source assembly 120. The second light source assembly 170 is electrically connected to the driver 160, and the driver 160 can drive the second light source assembly 170 to emit light, thereby increasing the number of light sources in the lamp 100, providing multiple light emission modes, and increasing the functionality of the lamp 100.

[0065] The second light source component 170 can be a ring structure or at least one plate structure. The second light source component 170 can cover the entire frame 110 or not cover the entire frame 110, that is, it can cover part of the frame 110.

[0066] The second light source component 170 can be a light strip, a light bulb, or a light bead, etc.

[0067] like Figure 6 As shown, in some embodiments, optionally, the outer side of the frame 110 has a receiving cavity 118, and the second light source assembly 170 is disposed in the receiving cavity 118.

[0068] In this embodiment, the outer side of the frame 110 has a receiving cavity 118, and the second light source assembly 170 is disposed in the receiving cavity 118, thereby protecting the second light source assembly 170 with the frame 110 and reducing the space occupied by the lamp 100.

[0069] The receiving cavity 118 can be a ring-shaped structure or a strip-shaped structure. The number of strip-shaped receiving cavities 118 can be one or more. The receiving cavity 118 can be distributed with a full circle of border 110 or not distributed with a full circle of border 110, that is, distributed with a partial border 110.

[0070] like Figure 1 As shown, in some embodiments, the second light source assembly 170 optionally surrounds the frame 110.

[0071] In this embodiment, the second light source component 170 has a ring-shaped structure and surrounds the frame 110, thereby ensuring the light emission effect of the second light source component 170.

[0072] That is, the second light source component 170 is a ring structure that surrounds the entire frame 110.

[0073] like Figure 3and Figure 6 As shown, in some embodiments, optionally, the frame 110 includes a frame 112 and a first protruding edge 114 disposed on the frame 112. The first light source assembly 120, the light guide assembly 140 and the back plate 150 are all disposed on the frame 112. The first protruding edge 114 is located at one end of the frame 112. The first protruding edge 114 and the back plate 150 are arranged side by side, and the first protruding edge 114 protrudes from the back plate 150.

[0074] In this embodiment, the frame 110 includes a frame body 112 and a first protruding edge 114. The first light source assembly 120, the light guide assembly 140, and the back plate 150 are all disposed on the frame body 112. The first protruding edge 114 is disposed at one end of the frame body 112. The first protruding edge 114 and the back plate 150 are arranged side by side. Furthermore, the first protruding edge 114 protrudes beyond the back plate 150, that is, the back plate 150 is lower than the end of the first protruding edge 114, thereby enabling the frame 110 to fit against the mounting surface and reducing the installation gap of the lamp 100.

[0075] The first protruding edge 114 is an annular structure and is disposed at one end of the frame 112. At least a portion of the back plate 150 is disposed at the end of the frame 112 having the first protruding edge 114, and the first protruding edge 114 surrounds the outer side of the back plate 150.

[0076] like Figure 3 and Figure 6 As shown, in some embodiments, optionally, the lamp 100 further includes a fastener 180 for fixing the back plate 150 and the frame 110. The fastener 180 passes through the back plate 150 and is fixedly connected to the frame 110. A first protruding edge 114 protrudes from the fastener 180.

[0077] In this embodiment, the lamp 100 also includes a fixing member 180 for fixing the back plate 150. The fixing member 180 passes through the back plate 150 and is fixed to the frame 110, thereby fixing the back plate 150 and the frame 110. Furthermore, the first protruding edge 114 protrudes from the fixing member 180, that is, the fixing member 180 is lower than the end of the first protruding edge 114, thereby making the frame 110 fit against the mounting surface and reducing the installation gap of the lamp 100.

[0078] The first protruding edge 114 is an annular structure and is disposed at one end of the frame 112. At least a portion of the fastener 180 is disposed at the end of the frame 112 having the first protruding edge 114, and the first protruding edge 114 surrounds the outside of the fastener 180.

[0079] The fastener 180 can be a screw, rivet, or clip, and the number of fasteners 180 can be one or more.

[0080] like Figure 3 and Figure 6As shown, in some embodiments, optionally, the frame 110 also includes a second protruding edge 116 disposed on the frame 112, the second protruding edge 116 being disposed on the inner side of the frame 112, and the light guide assembly 140 being mounted on the second protruding edge 116.

[0081] In this embodiment, the frame 110 also includes a second protruding edge 116 disposed inside the frame 112, and the light guide assembly 140 is mounted on the second protruding edge 116, thereby reducing the installation difficulty of the lamp 100 and facilitating the assembly of the lamp 100.

[0082] The second convex edge 116 can be a ring structure or at least one strip structure.

[0083] like Figure 3 As shown, in some embodiments, the luminaire 100 may optionally include a support 190 disposed between the light guide assembly 140 and the back plate 150.

[0084] In this embodiment, the lamp 100 also includes a support member 190 disposed between the light guide assembly 140 and the back plate 150, thereby supporting the light guide assembly 140 and the back plate 150 and ensuring the stability of the light guide assembly 140. The support member 190 can press the light guide assembly 140 and the first light source assembly 120 onto the frame 110.

[0085] Among them, the support component 190 can be a support pad, support foam, support plastic or support rubber, etc.

[0086] In some embodiments, the driver 160 may be a non-isolated driver, thereby reducing costs.

[0087] like Figures 1 to 7As shown, the lamp 100 provided by this utility model includes a frame 110, a light guide assembly 140, a driver 160, a first light source assembly 120, a back plate 150, and a support member 190. The frame 110 has an annular structure, and a cavity is formed on the inner side of the frame 110. The cavity is used to install the first light source assembly 120 and the light guide assembly 140. The first light source assembly 120 is installed between the light guide assembly 140 and the inner sidewall 1122 of the frame 110. The back plate 150 is fixed to the frame 110 by a fastener 180. A support member 190 is also provided between the back plate 150 and the light guide assembly 140 to press the light guide assembly 140 and the first light source assembly 120 into the cavity. The first light source assembly 120 includes a circuit 122 and a lamp board 132. The circuit 122 includes a lamp bead circuit 124, which includes a light-emitting diode. The circuit 122 also includes a wire 128. Since the space above the lamp bead circuit 124 depends on the thickness of the driver 160, and the space below the lamp bead circuit 124 depends on the arrangement of the wiring below, the fewer the wiring below the lamp bead circuit 124, the thinner the first light source assembly 120. The lamp bead circuit of the circuit 122 arranges the first line 126 above the lamp bead circuit 124 through the wire 128. Since the driver 160 is obviously larger than the space below the lamp bead circuit 124, the wire 128 is also arranged above the lamp bead circuit 124.

[0088] The first light source assembly 120 can be a single color temperature, or a dual color temperature or more color temperatures. The number of LEDs connected in series and in parallel is determined by the voltage of the LED circuit 124, the number of LED circuits 124, and the output voltage of the driver 160.

[0089] like Figure 4 As shown, the first light source component 120 has a single color temperature trace, and no trace is needed below the LED bead circuit 124. At this time, the thickness of the first light source component 120 can be minimized. The trace on the LED bead circuit 124 is a single color temperature trace. The circuit 122 uses three parallel LED bead circuits 124. Each LED bead circuit 124 includes four light-emitting diodes. Assuming that the voltage of the light-emitting diode is 36V and the power is 1W, then the output voltage of the driver 160 is 144V and the maximum power is 12W.

[0090] like Figure 5As shown, the first light source component 120 has two color temperature traces. There are two traces above the LED circuit 124. In this configuration, the first light source component 120 for both color temperatures is at its thinnest. Each color temperature circuit 122 uses three parallel LED circuits 124, and each LED circuit 124 includes four LEDs. Assuming the LED voltage is 36V and the power is 1W, the driver 160 output voltage is 144V, with a maximum power of 24W. The above two embodiments demonstrate the narrowest possible design for the first light source component 120 under different schemes. The number of LEDs does not affect the thickness of the first light source component 120.

[0091] The frame 110 can be configured with a receiving cavity 118 as needed. A second light source assembly 170 can be housed within the receiving cavity 118, thereby increasing the spatial luminous effect of the lamp 100. Both the first light source assembly 120 and the second light source assembly 170 are electrically connected to the driver 160. The driver 160 drives the first light source assembly 120 and the second light source assembly 170, thereby illuminating them. The first protruding edge 114 of the frame 110 is higher than the back plate 150 and the fixing member 180, allowing the edge of the lamp to be flush with the top after installation. The driver 160 is a non-isolated driver, making it more cost-effective.

[0092] The driver 160 is a non-isolated driver. The driver 160 is installed between the back plate 150 and the light guide assembly 140 to drive the first light source assembly 120 and / or the second light source assembly 170, making the lamp 100 more aesthetically pleasing and flat.

[0093] The back plate 150 is locked to the frame 110 by the fastener 180. A support 190 is provided between the back plate 150 and the light guide assembly 140 to press the light guide assembly 140 and the first light source assembly 120 onto the frame 110.

[0094] The first light source assembly 120 includes a circuit 122 and a lamp board 132. The circuit 122 includes a lamp bead circuit 124, which includes at least one light-emitting diode. The circuit 122 also includes a wire 128, through which the wiring is arranged above the light-emitting diode, making the first light source assembly 120 narrower and the lamp 100 thinner.

[0095] The first light source component 120 can be a single color temperature, or a dual color temperature or more color temperatures. The number of LEDs connected in series and in parallel depends on the voltage of the LEDs, the number of LEDs, and the output voltage of the driver 160. The scheme is highly variable, which helps to diversify the types of lamps 100.

[0096] The frame 110 can be equipped with a receiving cavity 118 as needed, and a second light source component 170 can be installed in the receiving cavity 118 to increase the spatial light-emitting effect of the product.

[0097] The first protruding edge 114 of the frame 110 is higher than the back plate 150 and the fastener 180, which allows the lamp 100 to be mounted on the top after installation.
