Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lighting, and in particular relates to a lighting lamp. Background Art
[0002] For electrical cabinets, especially large distribution cabinets or control cabinets, since the internal space of the electrical cabinet is relatively large and the ambient light environment where the electrical cabinet is installed is relatively dim, in order to ensure that personnel can clearly see the equipment and lines inside the cabinet when operating or repairing the cabinet, and avoid operating errors or safety hazards caused by insufficient light, it is required to be installed in the electrical cabinet.
[0003] However, existing lighting fixtures for electrical cabinets generally lack battery life and require a continuous power supply. The input power for these types of lighting fixtures is typically 110V or 220V AC, but typical industrial electricity is 380V AC. To meet the lighting's power needs, an additional transformer is required, significantly increasing costs. For high-voltage, high-current distribution cabinets or control cabinets, to ensure operator safety, it is generally required that the power supply inside the cabinet be disconnected after the cabinet door is opened. This disconnects the power supply to the lighting fixture, preventing it from providing illumination and resulting in poor compatibility across different scenarios. The need for an additional uninterruptible power supply for the lighting fixture significantly increases costs. Furthermore, conventional lighting fixtures cannot be adjusted for brightness, making them incompatible across different scenarios. To ensure the desired brightness, a brighter fixture is required, which can waste energy and cause discomfort to the eyes. Utility Model Content

The dimming module is powered by the charge / discharge module or the lithium battery pack and is used to adjust the brightness of the lamp beads on the lamp board.
[0006] Furthermore, an external switch is connected to the circuit connecting the dimming module and the lamp board, so as to form an interlocking control of the lamp beads on the lamp board.
[0007] Furthermore, an automatic / manual switch is provided on the circuit connecting the dimming module and the light board, and the external switch is connected in series to the circuit connecting the automatic end of the automatic / manual switch and the light board.

After the charge / discharge module detects the power of the lithium battery pack, the power of the lithium battery pack is displayed through the power indicator light. After the charge / discharge module detects the charge / discharge status of the lithium battery pack, it is displayed through the charge / discharge indicator light.
[0009] Furthermore, a power switch is provided on the circuit connecting the rectifier module to the external power supply.
[0010] Furthermore, the shell includes a mounting base, a lampshade and two end covers, the two end covers are correspondingly arranged at both ends of the mounting base, the lampshade is arranged on the mounting base and located between the two end covers, the lamp panel is arranged on the mounting base and located inside the lampshade, the rectifier module, charge / discharge module and dimming module are arranged in one of the end covers, and the lithium battery pack is arranged in the other end cover.

[0025] like Figures 1-8As shown, the present invention provides a lighting lamp comprising a housing, a lamp board 4, a rectifier module 5, a charge / discharge module 6, a dimming module 7, and a lithium battery pack. The lamp board 4 is specifically an LED lamp board, and its lamp beads 401 are LED lamp beads. A PCB connector is installed at one end of the lamp board 4 to facilitate the connection of electrical wires. The lamp board 4, rectifier module 5, charge / discharge module 6, dimming module 7, and lithium battery pack 8 are electrically connected and are all disposed within the housing. The rectifier module 5 is used to connect to an external power source such as an industrial power supply and output 5V DC power to provide input power for the charge / discharge module 6. The rectifier module 5 accepts a wide voltage input range of 100V to 380V, covering most industrial power supply ranges, eliminating the need for a dedicated transformer for the lighting lamp power supply. The rectifier module 5 also has overload, short-circuit, and undervoltage protection functions. The charge / discharge module 6 outputs 5V DC power to provide charging power for the lithium battery pack 8. The lithium batteries in the lithium battery pack 8 are 18650 or other types. The dimming module 7 is powered by the charge / discharge module 6 or the lithium battery pack 8 and is used to adjust the brightness of the lamp beads 401 on the lamp board 4 .
[0026] Among them, the charge / discharge module 6 has a charging and discharging function. Under normal use, the dimming module 7 is powered by the lithium battery pack 8. When the input voltage of the charge / discharge module 6 is greater than or equal to a certain value (such as 4.5V), it switches to the input end of the charge / discharge module 6 to power the dimming module 7; and the charge / discharge module 6 also has overcharge and over-discharge protection, that is, when the charge / discharge module 6 detects that the battery pack voltage is a certain value (such as 4.2V±1%), it automatically stops charging the lithium battery pack 8. When the charge / discharge module 6 detects that the lithium battery pack 8 voltage is a certain value (such as 3.3V±1%), it automatically cuts off the external discharge of the lithium battery pack 8. The dimming module 7 has a dimming knob 701, which is a potentiometer-type dimming knob. The dimming module 7 uses PWM to infinitely adjust the brightness of the lamp beads 401 on the lamp board 4. Specifically, by rotating the dimming knob 701, the dimming module 7 receives the voltage signal of the dimming knob 701, and converts the dimming voltage signal linearly into a PWM duty cycle, and then outputs a 3.7V constant current source to adjust the brightness of the lamp beads 401 on the lamp board 4.
[0027] The lighting lamp provided by the present invention, based on the setting of the rectifier module 5, can accept a wide voltage input within a certain range, covering most industrial power supply ranges, eliminating the need for a transformer and reducing costs. During use, the brightness of the lamp beads 401 on the lamp board 4 can be adjusted by the dimming module 7, that is, the lighting brightness can be adjusted to meet the lighting needs of different light and dark environments, saving electricity and avoiding damage to the operator's eyes caused by excessive lighting. In addition, the lighting lamp comes with a lithium battery pack 8, and combined with the setting of the charge / discharge module 6, it can perform corresponding charge and discharge control and management of the lithium battery pack 8. In the case where the power supply in the high-voltage, high-current distribution cabinet or control cabinet is cut off after the cabinet door is opened, there is no need to set up and connect an uninterruptible power supply. After the external power supply is disconnected, it can directly rely on the built-in lithium battery pack 8 for power supply. It has high compatibility and can be applied to electrical cabinets with different electrical requirements and other scenarios.
[0028] In the present invention, an external switch 10 is connected to the circuit connecting the dimming module 7 and the lamp board 4. The external switch 10 is a limit switch of the electrical cabinet door, a human body sensing switch or other external control switch. The external switch 10 is used to control the on and off of the power supply of the lamp board 4, thereby realizing interlocking control of the external switch 10 and the on and off of the lamp beads 401 on the lamp board 4.
[0029] In one embodiment of the present invention, the interlocking control of the lighting of the lamp beads 401 is performed only through the aforementioned external switch 10.
[0030] In another embodiment of the present invention, an automatic / manual switch 9 is also included. Figure 8 As shown, the automatic / manual switching switch 9 is provided on the circuit connecting the dimming module 7 and the lamp board 4, and the aforementioned external switch 10 is specifically connected in series on the circuit connecting the automatic end of the automatic / manual switching switch 9 and the lamp board 4. When the automatic / manual switching switch 9 is switched to the automatic mode, the power on and off of the lamp board 4 is controlled by the external switch 10, thereby realizing the interlocking control of the external switch 10 on the lighting of the lamp beads 401 on the lamp board 4. When the automatic / manual switching switch 9 is switched to the manual mode, it is applicable to the situation where the lighting of the lamp beads 401 is not controlled by the external switch 10, such as when the on or off state of the electrical cabinet is not required to control the lighting of the lamp beads 401, or when the external switch 10 is damaged and cannot form an interlocking control normally to connect the lamp board 4 to the power supply. Based on the setting of the automatic / manual switching switch 9, more options can be provided for the use of the lighting lamp, further improving the convenience of the use of the lighting lamp.
[0031] The present invention also includes a battery indicator light 11 and a charge / discharge indicator light 12, both of which are electrically connected to the charge / discharge module 6. After the charge / discharge module 6 detects the battery level of the lithium battery pack 8, the battery level indicator 11 displays the battery level. After the charge / discharge module 6 detects the charge / discharge status of the lithium battery pack 8, the charge / discharge indicator light 12 displays the status. This allows personnel to easily check the battery level and charge / discharge status of the lithium battery pack 8.
[0032] There are two charge / discharge indicator lights 12, one for indicating the current charging state and the other for indicating the current discharging state. There are four power indicator lights 11 (D1-D4), which are arranged sequentially on the housing to display the power level of the lithium battery pack 8 at different stages, specifically using a five-level interval display. When the lithium battery pack 8 is in the discharging state, its power level is displayed by the four power indicator lights 11 as shown in Table 1 below:
[0033] Table 1
[0034]
[0035] When the lithium battery pack 8 is in charging state, the power level thereof is displayed by the four power indicator lights 11 as shown in Table 2 below:
[0036] Table 2
[0037]
[0038] A power switch 13 is provided on the circuit connecting the rectifier module 5 to the external power supply, and the input of the external power supply is turned on and off by the power switch 13. A power indicator light can be further provided on the circuit between the power switch 13 and the rectifier module 5, and whether the power supply is connected is indicated by the on and off of the power indicator light.
[0039] In this utility model, the housing includes a mounting base 1, a lampshade 2, and two end caps 3. The two end caps 3 are respectively arranged at both ends of the mounting base 1. The lampshade 2 is arranged on the mounting base 1 and located between the two end caps 3. The lamp board 4 is arranged on the mounting base 1 and located inside the lampshade 2. The rectifier module 5, the charge / discharge module 6, and the dimming module 7 are arranged in one of the end caps 3, and the lithium battery pack 8 is arranged in the other end cap 3. The internal space of the two end caps 3 can be fully utilized to install the corresponding modules. The overall modular design of the lighting lamp facilitates installation and subsequent maintenance.
[0040] like Figure 5 、 Figure 6As shown, the rectifier module 5, the charge / discharge module 6, and the dimming module 7 are spaced apart in the height direction of the end cover 3. Insulating columns 14 are fixedly provided between the rectifier module 5 and the charge / discharge module 6, and between the charge / discharge module 6 and the dimming module 7 to support and separate adjacent modules, thereby ensuring the compactness of the installation of the aforementioned modules inside the end cover 3 and avoiding interference between adjacent modules.
[0041] In the present invention, the automatic / manual switch 9, battery indicator light 11, charge / discharge indicator light 12, and dimming knob 701 of the dimming module 7 are specifically arranged on the end cover 3 where the rectifier module 5, charge / discharge module 6, and dimming module 7 are located. This shortens the wiring between the rectifier module 5, charge / discharge module 6, and dimming module 7. The power switch 13 and its power indicator light are arranged on the end cover 3 where the lithium battery pack 8 is located.
[0042] The mounting base 1 is provided with several fixing posts 101 for correspondingly fixing the lamp panel 4 and the two end caps 3. The lampshade 2 is made of highly light-transmitting PC material. Notches 102 are provided on both sides of the mounting base 1. The shapes of the two sides of the lampshade 2 match the shapes of the notches 102. The two sides of the lampshade 2 are correspondingly inserted into the notches 102 on both sides of the mounting base 1, and the two ends of the lampshade 2 are inserted into the two end caps 3. After the two end caps 3 are fixed to the mounting base 1, the two end caps 3 correspond to the two ends of the lampshade 2, thereby fixing the lampshade 2. This arrangement can eliminate the need for a fixing structure for the lampshade 2, which helps reduce the overall structural complexity of the lighting fixture and makes installation, disassembly, and maintenance easier.
