Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture with an emergency detection module that is easy to install. Background Technology

[0002] Lighting fixtures, especially tri-proof lights, are generally equipped with emergency modules. These modules are typically used to provide emergency lighting during power outages, such as emergency exit lights and emergency evacuation indicator lights. These emergency modules usually integrate emergency testing components for self-testing, and the way these components are secured directly affects the overall stability, maintenance efficiency, and lifespan of the lighting fixture. A similar disclosure is made in Chinese utility model patent application CN202323507963.4 (authorization announcement number: CN221402946U) entitled "Lighting Fixtures".

[0003] Currently, the commonly used fixing methods for emergency module test components mostly employ screw fastening or snap-fit ​​connections. However, in practical applications, these traditional methods have been found to have systemic defects, urgently requiring improvement through structural innovation. Screw-fixing installation requires specialized tools such as electric drills, demanding high operator skills and proving inefficient in confined spaces or at heights. Secondly, repeated disassembly and reassembly can easily lead to thread stripping, especially on soft shell materials such as aluminum alloys, where repeated disassembly and reassembly increases the probability of failure. Furthermore, emergency test components often require frequent triggering, and stress concentration points created by screw fixing may cause micro-cracks in the plastic shell, posing a risk of structural failure over long-term use. Snap-fit ​​fixing, theoretically simplifying the operation process, also has certain shortcomings in practical application. Snap-fit ​​structures are generally made of engineering plastics, and after a certain number of opening and closing operations, their elastic modulus decreases significantly, leading to a reduction in clamping force.

[0004] Therefore, the installation structure of the existing emergency detection module for lighting fixtures needs further improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lamp that, in view of the current state of the prior art, has an emergency detection module that can be quickly disassembled and assembled, and is reliable and durable.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a lamp, comprising:

[0007] Lamp housing;

[0008] A support plate is disposed inside the lamp housing, and an emergency module and a switch test assembly electrically connected to the emergency module are provided on the support plate;

[0009] The switch test assembly includes a switch test body and a test button and a test indicator light on the switch test body. The switch test body is connected to the emergency module via a conductive wire. The switch test body is detachably mounted on the carrier plate by magnetic adsorption.

[0010] The switch test unit of the lighting fixture is connected to the emergency module via a conductive wire and is movable relative to the emergency module. Furthermore, the switch test unit is detachably mounted on the carrier plate via magnetic adsorption. This magnetic fixing method eliminates the need for traditional screws or clips, enabling the test component to be used immediately upon attachment. During installation, simply bring the switch test component close to the carrier plate for automatic adsorption and positioning; disassembly is straightforward, significantly reducing manual operation complexity. Compared to traditional methods, this effectively reduces disassembly and assembly time, making it particularly suitable for emergency lighting fixtures requiring frequent maintenance.

[0011] To further ensure the secure installation of the switch test body, a mounting hole extending from the front to the back of the support plate is provided. The switch test body is confined within the mounting hole. An annular step portion is also defined on the switch test body, which abuts against the outer periphery of the mounting hole. The annular step portion and the outer periphery of the mounting hole are magnetically attracted to each other. The mounting hole allows the switch test body to be confined by its outer contour. Combined with the magnetic attraction, this effectively ensures the secure installation of the switch test body.

[0012] As an improvement, a magnetic element is provided on one of the outer periphery of the annular step portion and the mounting hole, while a magnetically conductive portion is provided or constructed to be attracted by the magnetic element on the other. The aforementioned magnetically conductive portion can be understood as an independent component additionally provided on the outer periphery of the annular step portion or the mounting hole, such as a metal element or magnet that can be attracted. Alternatively, it can be understood that the corresponding area of ​​the outer periphery of the annular step portion or the mounting hole itself can be attracted by the magnetic element, meaning that its material itself is capable of being attracted by the magnetic element.

[0013] To further ensure the reliability of the switch test body being installed magnetically, the mounting hole is a strip-shaped hole, and mounting grooves are provided on the annular stepped portion in the area opposite to the left and right sides of the mounting hole. The magnetic components are provided in both mounting grooves, and the left and right sides of the mounting hole are correspondingly configured as the magnetic conductive portion.

[0014] To facilitate operators in checking whether the indicator light is flashing or lit when performing functional tests on the emergency module, the end of the switch test body that passes through the mounting hole and is visible on the front of the carrier plate is designated as the first end, and the other end opposite to the first end is designated as the second end. The test indicator light is located at the first end of the switch test body, and the test button is located at the second end of the switch test body.

[0015] As an improvement, the switch test body includes a fixed shell and an energized module disposed inside the fixed shell. The mounting slot is formed on the fixed shell. The test button and the test indicator light are both electrically connected to the energized module. The test button has a trigger part that protrudes outside the fixed shell.

[0016] To facilitate the installation of components such as the power-on module on the switch test body, the fixed housing includes a housing body with an opening at the top and a cover that is detachably installed at the opening at the top of the housing body. The trigger part of the test button is exposed through the cover.

[0017] To simplify the detachable connection structure between the shell body and the cover, the cover and the shell body are connected by a snap-fit ​​mechanism. It is conceivable that the cover and the shell body could also be connected by screws, adhesive, knob locking, or magnetic attachment.

[0018] Compared with existing technologies, the advantages of this utility model are as follows: The switch test body of the lamp is connected to the emergency module via a conductive wire, thus allowing it to move relative to the emergency module. Furthermore, the switch test body is detachably mounted on the carrier plate via magnetic adsorption. This magnetic fixing method eliminates the need for traditional screw fastening or clip structures, enabling the test component to be "plug and play." During installation, simply bringing the switch test component close to the carrier plate allows for automatic adsorption and positioning; disassembly is straightforward, significantly reducing the complexity of manual operation. Compared to traditional methods, it effectively reduces disassembly and assembly time, making it particularly suitable for emergency lighting scenarios requiring frequent maintenance.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0025] See Figures 1-4 A preferred embodiment of the lamp fixture of this utility model is shown. The lamp fixture includes a lamp housing 10, a support plate 20, an emergency module 22, and a switch testing assembly. The support plate 20 can be fixed to the inside of the lamp housing 10 by screws or a snap-fit ​​structure. The emergency module 22 can also be installed on the top surface (i.e., the back) of the support plate 20 by screws or a snap-fit ​​structure. The switch testing assembly is detachably fixed to the support plate 20 by magnetic attraction. The support plate 20 is also provided with a driving module and a light source (such as an LED light strip). The lamp housing 10 includes an upper housing 11 with an open bottom and a lampshade 12 installed at the bottom opening of the upper housing 11. The light source 21 on the support plate 20 generally faces the lampshade 12, that is, the light-emitting surface is arranged downwards. The arrangement and operation of the driving module and the light source 21 are existing technologies and will not be described in detail here.

[0026] See Figure 2 The switch testing assembly includes a switch testing body 30, which is connected to the emergency module 22 via a conductive wire 36 and is movable relative to the emergency module 22. The main inventive point of this embodiment is that the switch testing body 30 is detachably fixed to the carrier plate 20 via magnetic attraction. The switch testing body 30 includes a fixing shell 31, a test indicator light 37, a test button 34, and a power-on module 33. The test indicator light 37 and the test button 34 are integrated into the aforementioned power-on module 33 and are electrically connected to it. The power-on module 33 is located inside the fixing shell 31. The fixing shell 31 can be injection molded from engineering plastic. The fixing shell 31 includes a shell body 311 and a cover 312. The top of the shell body 311 is open, and the cover 312 is connected to the shell body 311 via a snap-fit ​​structure. The snap-fit ​​structure includes elastic hooks on the side wall of the shell body 311 and a slot on the inside of the cover 312. Pressing the cover 312 allows for quick assembly and disassembly, facilitating the maintenance of the power-on module 33.

[0027] See Figure 3 and Figure 4 The support plate 20 has mounting holes 200, which are strip-shaped holes that penetrate from the front to the back of the support plate 20. The left and right edges of the mounting holes 200 can be made of a magnetically conductive material. The switch test body 30 (mainly on the side wall of the housing body 311) has an annular stepped portion 313. Two mounting grooves 3130 are symmetrically opened on the left and right sides of the annular stepped portion 313. Each mounting groove 3130 is fitted with a magnetic component 32, which can be a magnet, such as a neodymium iron boron magnet, and can be fixed by adhesive. During installation, the switch test body 30 is confined in the mounting holes 200, and the annular stepped portion 313 on the switch test body 30 abuts against the outer periphery of the mounting holes 200 and is magnetically attracted to each other. The magnetically conductive outer periphery of the mounting holes 200 and the magnetic component 32 are attracted to each other, achieving a secure fixation of the switch test assembly. During disassembly, a suitable pulling force or pushing force can be applied to separate the components. The mounting holes 200 on the support plate 20 allow the switch test body 30 to be limited by the outer contour of the mounting holes 200. In addition, the magnetic adsorption method can effectively ensure the secure installation of the switch test body 30.

[0028] See Figure 4 After the switch test body 30 is installed in place, the end of the switch test body 30 that passes through the mounting hole 200 and is visible on the front of the support plate 20 is designated as the first end 301 (i.e., the bottom of the housing body 311), and the other end opposite to the first end 301 is designated as the second end 302, which is the location of the cover 312 at the opening of the housing body 311. A test indicator light 37 is located at the first end 301 of the switch test body 30, while a test button 34 is located at the second end 302 of the switch test body 30. The test button 34 has a trigger portion 341 that protrudes outside the cover 312 of the fixed housing 31. During testing, the test button 34 is located at the top for easy pressing by the operator, while the test indicator light 37 is located at the first end 301, facing the lampshade 12. When performing functional tests on the emergency module 22, it is possible to visually observe whether the indicator light 37 is flashing or illuminated.

[0029] The switch test body 30 of the lighting fixture is connected to the emergency module 22 via conductive wire 36 and is movable relative to the emergency module 22. Furthermore, the switch test body 30 is detachably mounted on the carrier plate 20 via magnetic attraction. This magnetic fixing method eliminates the need for traditional screws or clips, enabling "plug-and-play" application of the test component. During installation, simply bringing the switch test component close to the carrier plate allows for automatic adsorption and positioning; disassembly is straightforward, significantly reducing manual operation complexity. Compared to traditional methods, this effectively reduces disassembly and assembly time, making it particularly suitable for emergency lighting fixtures requiring frequent maintenance. On the other hand, the magnetic fixing method overcomes the limitations of traditional physical structures. By adjusting the magnet arrangement, it can adapt to different carrier plate specifications, improving compatibility. Simultaneously, standardized magnetic modules enable cross-product line universality, reducing mold development costs.

[0030] The disassembly, assembly, and use process of the lamp switch test assembly in this embodiment is as follows:

[0031] Align the annular stepped portion 313 of the switch test body 30 with the mounting hole 200. Once in place, the magnetic component 32 on the switch test body 30 automatically adheres to the magnetic edge of the mounting hole 200, completing the positioning. For disassembly, apply appropriate force vertically to the switch test body 30; the switch test body 30 separates from the support plate 20. Tool-free operation is required, making it suitable for maintenance at heights or in confined spaces. During testing, press the trigger portion 341 of the test button 34; the emergency module 22 initiates a self-test program, and the test indicator light 37 illuminates or flashes according to the test results.

[0032] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, the mounting positions of the magnetic part and the magnetic component 32 can be interchanged. That is, magnets are embedded in the edge of the mounting holes 200 of the carrier plate 20, while the annular step portion 313 of the switch test assembly uses a magnetic part that can be attracted by a magnet, such as being made of magnetically conductive stainless steel. Alternatively, multiple standardized mounting holes 200 are provided on the carrier plate 20 and arranged in a corresponding array. The position of the magnetic component 32 of the switch test assembly is designed to be adjustable. Therefore, when multiple test assemblies need to be installed in the same lamp, their positions can be flexibly adjusted. Furthermore, it is compatible with carrier plates of different lamp models, enabling the magnetic module to be used across product lines.
