Description

Technical Field

[0001] This utility model relates to the field of lighting power supply technology, specifically to a color temperature adjustable power supply and lighting fixture with a quick-connect emergency power supply interface. Background Technology

[0002] Traditional lighting fixtures are gradually being replaced by LED lights, and all LED lights require an LED driver. As people's demands for LED lighting functionality increase, adjustable color temperature LED lights have emerged. These are achieved by adding a color temperature toggle switch between the LED driver and the light panel, allowing for quick adjustment of the LED light's color temperature. However, if the LED light needs to continue operating normally in the event of a power outage, an additional emergency power supply is required. Since the color temperature toggle switch can only function by being directly connected to the light panel, the process of installing an emergency power supply for existing adjustable color temperature LED lights is quite cumbersome. It requires first disconnecting the color temperature toggle switch from the LED driver, and then connecting the emergency power supply between the toggle switch and the LED driver. This not only consumes a significant amount of installation time but also increases the number of power wires inside the LED light, frequently leading to reversed polarity and rendering the light unusable, posing a significant safety hazard. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a color temperature adjustable power supply and lighting fixture with a quick-connect emergency power interface.

[0038] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0039] Example 1:

[0040] Reference Figures 1-3 , Figure 1 This is a schematic diagram of the color temperature adjustment power supply with a quick-connect emergency power interface in the embodiment. Figure 2 This is a schematic diagram of the structure of the first plug-in terminal piece in the embodiment. Figure 3 The circuit diagram of the color temperature adjusting power supply with quick-connect emergency power interface in this embodiment is shown. The color temperature adjusting power supply with quick-connect emergency power interface in this embodiment includes a power supply main body 1, a first plug-in terminal 2 and a color temperature adjusting component 3. The power supply main body 1 includes a circuit board 11 and a power module 12. The power module 12, the first plug-in terminal 2 and the color temperature adjusting component 3 are all integrated on the circuit board 11. The first plug-in terminal 2 is electrically connected to the power module 12 and the color temperature adjusting component 3 respectively. The color temperature adjusting component 3 is electrically connected to the lamp. The first plug-in terminal 2 has a first expansion plug interface 21.

[0041] In this embodiment, the color-temperature adjustable power supply with a quick-connect emergency power interface is used as a driver for the lamp panel in a lighting fixture. Through the color-temperature adjustment component 3, the color temperature of the lamp panel can be adjusted to meet the lighting needs of different scenarios. Furthermore, through the first expansion interface 21, this embodiment also has two usage states: a normal state and an expanded state. In the normal state, jumper blocks and other conductive components are plugged into the first expansion interface 21. At this time, the power module is electrically connected to the color-temperature adjustment component 3 through the conductive first connector 2, and the color-temperature adjustment component 3 is electrically connected to the lamp panel. Adjusting the color-temperature adjustment component 3 adjusts the color temperature of the lamp panel. In the expanded state, the emergency power supply is directly plugged into the first expansion interface 21. At this time, the emergency power supply is electrically connected to both the power module and the color-temperature adjustment component 3, thus quickly expanding into a lighting fixture driver power supply with adjustable color temperature and emergency power capabilities, broadening its application scenarios. More importantly, by integrating the power module 12, the first plug-in terminal 2, and the color temperature adjustment component 3 into the circuit board 11 to form an integrated drive power supply, the integration of the drive power supply structure is improved. At the same time, the emergency power supply can be directly plugged into the first expansion interface 21 to quickly expand into a lamp driver power supply with adjustable color temperature and emergency power supply. This greatly simplifies the steps of adding the emergency power supply to the lamp driver power supply, improves expansion and installation efficiency, eliminates the need to repeatedly plug and unplug the power cord, avoids the situation where the positive and negative terminals of the power cord are reversed, which may cause the lamp to be scrapped, and improves safety.

[0042] Reference Figure 4 , Figure 4This is a schematic diagram of the color temperature adjustment component with expansion terminals in the embodiment. Preferably, the first expansion interface 21 is provided with a positive input terminal 211, a negative input terminal 212, a positive output terminal 213, and a negative output terminal 214. The positive and negative terminals of the power module 12 are electrically connected to the positive input terminal 211 and the negative input terminal 212, respectively. The negative output terminal 214 is electrically connected to the input terminal of the color temperature adjustment component 3. The positive output terminal 213 and the output terminal of the color temperature adjustment component 3 are electrically connected to the lamp, respectively. In specific applications, the first expansion interface 21 in this embodiment is provided with four connection terminals, which are respectively connected to the positive input terminal 211, the negative input terminal 212, the positive output terminal 213, and the negative output terminal 214 on the circuit board 11, wherein the positive and negative terminals of the power module 12 are electrically connected to the positive input terminal 211 and the negative input terminal 212, respectively. The positive output terminal 213 is electrically connected to the positive terminal of the lamp board. In practical applications, the circuit board 11 is provided with an LED+ terminal, which is connected to the positive terminal of the lamp board via a power cord, thus electrically connecting the positive output terminal 213 to the positive terminal of the lamp board. The negative output terminal 214 is electrically connected to the input terminal of the color temperature adjustment component 3. In this embodiment, the color temperature adjustment component 3 is a color temperature toggle switch, specifically a three-position color temperature toggle switch with one input interface and two output interfaces. The negative output terminal 214 is connected to the input interface of the color temperature adjustment component 3. The circuit board 11 is also provided with an LEDW- terminal and an LEDC- terminal. The negative terminal of the lamp board is connected to the LEDW- terminal and the LEDC- terminal respectively via two power cords, thus electrically connecting the two output interfaces of the color temperature toggle switch to the negative terminal of the lamp board. In this way, the color temperature of the lamp board can be adjusted by toggling the color temperature toggle switch. Of course, in other embodiments, the connection terminals between the circuit board 11 and the lamp board can also be LEDW+, LEDC+, and LED-. The LEDW+ and LEDC+ terminals are connected to the positive terminal of the lamp board via two power lines, while the LED- terminal is connected to the negative terminal of the lamp board via a power line. The specific configuration can be determined according to actual application requirements, and will not be elaborated further here. Furthermore, in other embodiments, the color temperature adjustment component 3 can also be a four- or five-level color temperature toggle switch; the number of levels for the color temperature toggle switch is not limited here.

[0043] Reference Figure 5 , Figure 5The circuit diagram of the emergency power supply component in the embodiment is shown below. Preferably, the color temperature adjusting power supply with a quick-connect emergency power interface further includes an emergency power supply component 4. The emergency power supply component 4 is plugged into the first expansion interface 21 and is electrically connected to the power module 12 and the color temperature adjusting component 3, respectively. In specific applications, the emergency power supply component 4 includes an emergency power supply body 41 and an adapter 42. The adapter 42 is connected to the emergency power supply body 41 and has four docking terminals: LED-, LED+, controlgear-, and controlgear+. When the adapter 42 is plugged into the first expansion interface 21, the four docking terminals of the adapter 42 are respectively connected to the negative output terminal 214, the positive output terminal 213, the negative input terminal 212, and the positive input terminal 211. In this way, the emergency power supply body 41 can be directly and quickly installed onto the color temperature adjusting power supply with a quick-connect emergency power interface. Specifically, the emergency power supply body 41 is an existing LED emergency power supply.

[0044] Rereference Figure 2 and Figure 5 Preferably, the positive input terminal 211 and the positive output terminal 213 are arranged side by side and adjacent to each other, and the negative input terminal 212 and the negative output terminal 214 are arranged side by side and adjacent to each other. In specific applications, in this embodiment, the positive input terminal 211, the positive output terminal 213, the negative input terminal 212, and the negative output terminal 214 are arranged linearly in sequence. It can be understood that the four terminals of the adapter 42 are the controlgear+ terminal, the LED+ terminal, the controlgear- terminal, and the LED- terminal, arranged linearly in sequence.

[0045] Example 2:

[0046] Reference Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the first plug-in terminal and the conductive element in the embodiment. Figure 7The diagram below illustrates the structure of the jumper block in this embodiment. The difference between the color temperature adjusting power supply with a quick-connect emergency power interface in this embodiment and that in Embodiment 1 is that the first expansion interface 21 in this embodiment does not contain an emergency power supply component 4, but instead contains a conductive component 5. In practical applications, the color temperature adjusting power supply with a quick-connect emergency power interface further includes the conductive component 5, which is inserted into the first expansion interface 21, electrically connecting the positive input terminal 211 and the positive output terminal 213, and electrically connecting the negative input terminal 212 and the negative output terminal 214. It is understandable that by setting the conductive element 5, the positive input terminal 211 and the positive output terminal 213 are electrically connected, and the negative input terminal 212 and the negative output terminal 214 are electrically connected. In other words, the power module and the color temperature adjustment element 3 are electrically connected, which is equivalent to a driver power supply that can adjust the color temperature. The emergency power supply function is canceled, and the structure is simplified. Of course, when the emergency power supply function is needed, the conductive element 5 is pulled out from the first expansion interface 21, and the emergency power supply element 4 in Embodiment 1 is plugged into the first expansion interface 21 to quickly expand it into a lamp driver power supply with adjustable color temperature and emergency power supply.

[0047] Rereference Figure 7 Preferably, the conductive component 5 includes two jumper blocks 51, which are respectively plugged into the first expansion interface 21. One jumper block 51 is electrically connected to the positive input terminal 211 and the positive output terminal 213, and the other jumper block 51 is electrically connected to the negative input terminal 212 and the negative output terminal 214. By setting the jumper blocks 51, when no emergency power supply is plugged into the first expansion interface 21, plugging the jumper blocks 51 into the first expansion interface 21 will change the terminals in the first expansion interface 21 from the original disconnected state to the conductive state, so that the power module and the color temperature adjustment component 3 can be electrically connected. Specifically, the jumper block 51 includes an insulating sleeve 511 and a conductive piece 512 passing through the insulating sleeve 511. The two insulating sleeves 511 are respectively inserted into the first expansion interface 21. One conductive piece 512 is electrically connected to the positive input terminal 211 and the positive output terminal 213, and the other conductive piece 512 is electrically connected to the negative input terminal 212 and the negative output terminal 214. Furthermore, the two jumper blocks 51 can be integrally formed into one component, or they can be separated into two independent components.

[0048] Example 3:

[0049] Reference Figure 8 , Figure 8This is a schematic diagram of the color temperature adjusting power supply with a quick-connect emergency power interface in Embodiment 3. The difference between this embodiment and Embodiment 1 is that the latter includes a toggle switch 6, which is located on the circuit board 11 and acts on the first plug-in terminal 2. When the toggle switch 6 is toggled, it has an on / off state. In the on / off state, the positive input terminal 211 is connected to the positive output terminal 213, and the negative input terminal 212 is connected to the negative output terminal 214. In the off / off state, all connections between the positive input terminal 211, negative input terminal 212, positive output terminal 213, and negative output terminal 214 are disconnected. In practical applications, the toggle switch 6 is a toggle switch. It is understandable that the toggle switch is located near the first plug-in terminal 2. After the toggle switch is toggled, its conduction levers can move closer to or further away from the first plug-in terminal 2. That is, in the conducting state, one conduction lever contacts the positive input terminal 211 and the positive output terminal 213 respectively and makes them conductive, while the other conduction lever contacts the negative input terminal 212 and the negative output terminal 214 respectively and makes them conductive. In this way, the power module can still be electrically connected to the color temperature adjustment component 3 without plugging in the emergency power supply or the jumper block 51. That is, this embodiment saves the jumper block 51 component compared with embodiment two. In the disconnected state, the conduction levers are away from the positive input terminal 211, the negative input terminal 212, the positive output terminal 213, and the negative output terminal 214. At this time, the emergency power supply component 4 in embodiment one can be plugged into the first expansion interface 21 to expand it into a lamp driver power supply with adjustable color temperature and emergency power supply.

[0050] Example 4:

[0051] The lamp in this embodiment includes a lamp board, a lamp housing, and a color temperature adjusting power supply with a quick-connect emergency power interface as described in Embodiment 1. The positive terminal of the lamp board is connected to the LED+ terminal of the circuit board 11, and the negative terminal of the lamp board is connected to the LEDW- terminal and LEDC- terminal of the circuit board 11, respectively. Both the lamp board and the circuit board 11 are housed inside the lamp housing.

[0052] Example 5:

[0053] Reference Figures 9-11 , Figure 9 This is a schematic diagram of the color temperature adjustment power supply with a quick-connect emergency power supply interface in Embodiment 5. Figure 10 This is a circuit diagram of the color temperature adjustment power supply with a quick-connect emergency power interface in Example 5. Figure 11This is a circuit diagram of the emergency power supply in Embodiment 5. The difference between the color temperature adjusting power supply with quick-connect emergency power interface in this embodiment and Embodiment 1 is that the color temperature adjusting power supply with quick-connect emergency power interface in this embodiment also includes a second plug-in terminal 7. The second plug-in terminal 7 is integrated into the circuit board 11 and is electrically connected to the power module 12. The second plug-in terminal 7 has a second expansion interface 71. In specific applications, the number of adapters 42 of the emergency power supply 4 in this embodiment is two. One adapter 42 has four docking terminals: LED-, LED+, controlgear-, and controlgear+, which can be plugged into the first expansion interface 21. The other adapter 42 has an L in, LOUT, N, and SL in terminal. The second expansion interface 71 has four terminals corresponding to the other adapter 42. The plug-in connection method and principle between the other adapter 42 and the second expansion interface 71 are the same as those between the first adapter 42 and the first expansion interface 21, and will not be described again here. Of course, in other embodiments, the emergency power supply 4 can be omitted, and instead, the conductive element 5 can be plugged into the first expansion interface 21 and the second expansion interface 71 to become a driver power supply capable of adjusting color temperature. In specific applications, the emergency power supply 4 in this embodiment is an existing emergency power supply with a power failure detection function, which is equipped with a detection button. When the two adapters 42 of the emergency power supply 4 are plugged into the first expansion interface 21 and the second expansion interface 71 respectively, pressing the detection button will switch to using only the emergency power supply 4 to power the light board. If the light board lights up, it indicates that the emergency power supply 4 is functioning normally. In this way, the function of the emergency power supply 4 can be quickly tested. Compared with the first embodiment, the function of the emergency power supply 4 can be tested without cutting off the power, improving the efficiency of maintenance. At the same time, it can also meet the safety certification requirements of different countries and regions for emergency power supplies, thus broadening the application scenarios. Specifically, the integration onto the circuit board 11 described in this embodiment can be either direct or indirect. That is, the first plug-in terminal 2 and the second plug-in terminal 7 can be directly integrated onto the circuit board 11, or they can be connected by leading wires from the circuit board 11 using a power cable, facilitating the connection of the emergency power supply component 4. In other embodiments, the second expansion interface 71 may only have three terminals: L, L', and N, and the other adapter 42 may have correspondingly three terminals: L in, L OUT, and N. Further details are omitted here.

[0054] Example 6:

[0055] Reference Figures 12-14 , Figure 12This is a schematic diagram of the color temperature adjustment power supply with a quick-connect emergency power supply interface in Embodiment Six. Figure 13 This is a schematic diagram of the commutation switch component in Embodiment Six. Figure 14 This is a circuit diagram of the color temperature adjusting power supply with a quick-connect emergency power interface in Embodiment Six. The difference between this embodiment and Embodiment Five is that the latter includes a phase-switching switch 8, integrated on the circuit board 11, and electrically connected to the L-terminal of the second plug-in terminal 7. The phase-switching switch 8 allows selection of one of the three phase lines for connection, enabling power supply to be provided to any one phase line according to actual conditions, thus achieving phase switching. Specifically, the phase-switching switch 8 is a conventional three-phase phase-switching switch; the specific principle and switching process are not detailed here.

[0056] Example 7:

[0057] Reference Figure 15 , Figure 15 This is a circuit diagram of the color temperature adjusting power supply with a quick-connect emergency power interface in Embodiment 7. The difference between this embodiment and Embodiment 6 is that this embodiment includes two toggle switches 6. One toggle switch 6 (not shown) is located on the circuit board 11, close to the first plug-in terminal 2, and acts on the first plug-in terminal 2. The detailed principle is the same as in Embodiment 3, and will not be repeated here. The other toggle switch 6 is located on the circuit board 11, close to the second plug-in terminal 7, and acts on the second plug-in terminal 7. Toggling the other toggle switch 6 also has an on / off state. In the on state, the L and L' terminals of the second plug-in terminal 7 are connected. In the off state, the L and L' terminals of the second plug-in terminal 7 are disconnected. The specific principle is similar to that of one of the toggle switches 6, and will not be repeated here. In this way, without the need for an external emergency power supply 4, simply toggling the toggle switch 6 is enough to ensure electrical connection between the power module and the color temperature adjustment component 3, eliminating the need for the jumper block 51 and improving user convenience. Of course, in other embodiments, the toggle switch 6 can be omitted and the jumper block 51 can be used instead.

[0058] In summary, by setting the color temperature adjustment component 3, the color temperature of the lamp panel can be adjusted to meet the lighting needs of different scenarios. Furthermore, through the first expansion interface 21, this embodiment also has two usage states: a normal state and an expansion state. In the normal state, jumper blocks and other conductive components are plugged into the first expansion interface 21. At this time, the power module is electrically connected to the color temperature adjustment component 3 through the conductive first connector 2, and the color temperature adjustment component 3 is electrically connected to the lamp panel. Adjusting the color temperature adjustment component 3 allows for adjustment of the lamp panel's color temperature. In the expansion state, the emergency power supply is directly plugged into the first expansion interface 21. At this time, the emergency power supply is electrically connected to both the power module and the color temperature adjustment component 3, thus quickly expanding into a lamp driver power supply with adjustable color temperature and emergency power capabilities, broadening the application scenarios. More importantly, by integrating the power module 12, the first plug-in terminal 2, and the color temperature adjustment component 3 into the circuit board 11 to form an integrated drive power supply, the integration of the drive power supply structure is improved. At the same time, the emergency power supply can be directly plugged into the first expansion interface 21 to quickly expand into a lamp driver power supply with adjustable color temperature and emergency power supply. This greatly simplifies the steps of adding the emergency power supply to the lamp driver power supply, improves expansion and installation efficiency, eliminates the need to repeatedly plug and unplug the power cord, avoids the situation where the positive and negative terminals of the power cord are reversed, which may cause the lamp to be scrapped, and improves safety.
