Description

Technical Field

[0001] This invention relates to indicator lights, specifically indicator lights. Background Technology

[0002] Currently, indicator lights are divided into two types: anti-interference and non-anti-interference. When the user's environment is poor and electromagnetic interference is severe, even if the indicator light circuit is disconnected, an induced voltage will still be generated across the indicator light. Since indicator lights use LED light-emitting elements, the lighting voltage threshold is generally only 5V. As long as an induced voltage of more than 5V is generated, the non-anti-interference indicator light will light up slightly, which can mislead the user. Therefore, these users need to choose anti-interference indicator lights.

[0003] Compared to non-interference-resistant indicator lights, anti-interference indicator lights have an additional resistor connected in parallel in the internal circuit of the product. This can increase the indicator light's lighting voltage threshold, such as 20V, 30V, or 40V, thereby achieving the function of anti-interference.

[0004] However, some users are unaware whether their environment will generate induced voltage, and therefore choose non-interference-resistant products. Only after installation and use do they discover that the indicator light is lit due to induced voltage. In this case, they can only remove the non-interference-resistant indicator light and purchase and replace it with an interference-resistant one, which can easily lead to cost waste and also delays the selection of the appropriate light fixture. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an indicator light that can switch from a non-interference-resistant indicator light to an interference-resistant indicator light, thereby reducing the user's monetary cost.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an indicator light, comprising a housing, a light-emitting component disposed within the housing, a wiring component disposed within the housing, and the light-emitting component and the wiring component being electrically connected via a conductive element, characterized in that it further comprises an anti-interference accessory detachably mounted to the housing, the anti-interference accessory having a contact for connecting the conductive element, wherein when the anti-interference accessory is mounted on the housing, the contact and the conductive element cooperate to form a conductive contact, thereby electrically connecting the anti-interference accessory to the conductive element via the contact.

[0007] As a further improvement of the present invention, the conductive component includes two metal components, and the two metal components correspond to the positive and negative terminals or the neutral and live wires, respectively; the light-emitting component is electrically connected to the wiring component through the two metal components and obtains power through the wiring component; the anti-interference accessory has a contact component at the position corresponding to the two metal components, and when the anti-interference accessory is installed on the housing, the two contact components are in contact with the corresponding metal components to connect the anti-interference accessory in parallel to the light-emitting component.

[0008] As a further improvement of the present invention, the wiring assembly includes two terminals for connecting power lines, and two metal parts are formed by extending from the two terminals respectively.

[0009] As a further improvement of the present invention, the metal part is soldered to the circuit board of the light-emitting component or plugged in through a conductive socket.

[0010] As a further improvement of the present invention, the contact element has a clip structure and is used for inserting and clamping a metal part to form a conductive contact.

[0011] As a further improvement of the present invention, the contact is formed by bending a conductive metal sheet to form a clip structure, and one end of the clip structure corresponding to the anti-interference accessory is raised to form an opening for inserting a metal part. The opening is formed by the raised part of the clip structure to form a guide slope, so as to guide the metal part to be inserted into the clip structure and clamped.

[0012] As a further improvement of the present invention, the housing is also provided with a slot for a metal part to pass through, at least a portion of which is located in the slot, the slot being used to limit the swinging or deformation of the metal part or to position the metal part.

[0013] As a further improvement of the present invention, the width of a segment of the metal part corresponding to the wiring assembly is greater than the width of a segment of the metal part corresponding to the light-emitting assembly, and the position of the contact element corresponds to the position of the metal part with a larger width, and the position of the slot also corresponds to the position with a larger width.

[0014] As a further improvement of the present invention, the anti-interference accessory is detachably mounted on the side of the housing, and the side of the housing is provided with a window for mounting the anti-interference accessory, which is used to allow the contact to enter the interior of the housing; the shape of the window is adapted to the shape of the anti-interference accessory.

[0015] As a further improvement of the present invention, the latch is used to engage with the edge of the window to snap the anti-interference accessory onto the housing.

[0016] As a further improvement of the present invention, a notch is provided on the anti-interference accessory at the position corresponding to the buckle, the notch being used for buckle deformation; when the anti-interference accessory is installed by snapping it into the housing, the buckle is located inside the housing, and the notch is located outside the housing.

[0017] The beneficial effects of this invention are:

[0018] 1. This solution allows the indicator light itself to be used independently without anti-interference accessories, which can reduce the user's operating costs.

[0019] 2. The anti-interference accessories in this solution are detachable and can be installed on the housing. They can be installed retrofitted without removing and replacing the already installed indicator lights. This method is efficient and saves time.

[0020] 3. It has a flexible switching function, and can switch between anti-interference and non-anti-interference states.

[0021] 4. By using the conductive parts between the wiring assembly and the light-emitting assembly, the anti-interference accessory makes conductive contact with the conductive parts, and the anti-interference accessory is connected between the wiring assembly and the light-emitting assembly, thereby achieving the anti-interference function.

[0030] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0031] Reference Figure 1-7 As shown,

[0032] An indicator light includes a housing 1, a light-emitting component 2 disposed within the housing 1, a wiring component 3 disposed within the housing 1, the light-emitting component 2 and the wiring component 3 being electrically connected via a conductive element, and further includes an anti-interference accessory 5 detachably mounted to the housing 1. The anti-interference accessory 5 has a contact 51 for connecting to the conductive element. When the anti-interference accessory 5 is mounted on the housing 1, the contact 51 cooperates with the conductive element to form a conductive contact, so as to electrically connect the anti-interference accessory 5 to the conductive element via the contact 51.

[0033] Reference Figure 1 , 2 As shown in Figures 4 and 6, in this solution, the anti-interference accessory 5 is detachably connected to the housing 1. Therefore, it is not necessary to purchase the anti-interference accessory 5 at the beginning of the sale, which can reduce the procurement cost according to the needs. However, when the user purchases and uses the product, if the user finds that the environment itself is in an electromagnetic interference environment, the user can continue to purchase the anti-interference accessory 5. The anti-interference is achieved through the installation between the accessory and the housing 1, which avoids the problem of the indicator light illuminating misleadingly due to electromagnetic interference in the working environment.

[0034] When installing the anti-interference accessory 5 onto the housing 1, first align the contact 51 with the conductive component, then install the anti-interference accessory 5 onto the housing 1. With the installation of the anti-interference accessory 5, contact 51 and the conductive component can make contact and conduct electricity. The conductive component is used to connect the light-emitting component 2 and the wiring component 3, and can be a metal sheet, copper post, or wire. Contact 51 and the conductive component cooperate to make contact, achieving conductive contact. Then, the anti-interference accessory 5 is connected to the conductive component to achieve conductivity and provide anti-interference functionality.

[0035] Generally, the wiring assembly 3 and the light-emitting assembly 2 are located at a certain distance, and they are connected by a conductive component, i.e., electrically connected through a conductive element. This distance is generally quite long, so the conductive element also has a certain length. This solution is based on utilizing the length of this conductive element. The contact 51 of the aforementioned anti-interference accessory 5 is used to make contact with the conductive element, thereby achieving an electrical connection and connecting the anti-interference accessory 5 between the light-emitting assembly 2 and the wiring assembly 3. The most obvious feature of this solution is that the anti-interference accessory 5 cooperates with the conductive element between the light-emitting assembly 2 and the wiring assembly 3, and the two are connected to the light-emitting assembly 2 and the wiring assembly 3 through conductive contact.

[0036] In the preferred embodiment, the anti-interference accessory 5 is installed from the side of the housing 1, which makes it easier to make contact with the conductive parts. The wiring assembly 3 and the light-emitting assembly 2 are generally distributed at both ends of the housing 1. Therefore, installing it from the side makes it easier for the contact 51 on the anti-interference accessory 5 to make contact with the conductive parts.

[0037] In this solution, the anti-interference accessory 5 can be installed on the housing 1 and then detachably mounted on the housing 1 using screws.

[0038] This fixing method requires a through hole to be reserved on the housing 1 at the position for installing the anti-interference accessory 5, so that the screw can be screwed in. The screw can be tightened by using the through hole to install the anti-interference accessory 5 on the housing 1. Of course, the housing 1 needs to have a through hole or opening reserved so that the contact 51 can enter the interior of the housing 1 and make contact with the conductive part.

[0039] The contact 51 can be made of an elastic metal sheet. After contacting the conductive element, it deforms as the force of contact increases. This deformation allows the contact 51 to remain firmly attached to the conductive element, thus completing the conductive contact.

[0040] Reference Figure 2 , 3 As shown in Figures 4 and 5, in this scheme, the conductive component includes two metal parts 4, and the two metal parts 4 correspond to the positive and negative poles or the neutral and live wires, respectively; the light-emitting component 2 is electrically connected to the wiring component 3 through the two metal parts 4, and obtains power through the wiring component 3; the anti-interference accessory 5 has a contact part 51 at the position corresponding to the two metal parts 4. When the anti-interference accessory 5 is installed on the housing 1, the two contact parts 51 are in contact with the corresponding metal parts 4, so as to connect the anti-interference accessory 5 in parallel to the light-emitting component 2.

[0041] Two metal parts 4 are used for conducting electricity and can cooperate with the contact 51, respectively corresponding to the positive and negative terminals of the power supply or the neutral and live wires, to obtain power and supply power to the light-emitting component 2. The wiring component 3 is connected to the power supply. Correspondingly, there are also two contact parts 51, which allow the anti-interference accessory 5 to be connected in parallel on the light-emitting component 2.

[0042] It is worth mentioning that the anti-interference of the light-emitting component 2 is mainly achieved by incorporating a resistor. The anti-interference accessory 5 contains a resistor, and each end of the resistor is connected to a contact 51. The contact 51 makes conductive contact with the metal part 4, thereby connecting the resistor in parallel with the light-emitting component 2.

[0043] Reference Figure 1 , 3 As shown in Figures 5 and 6, in a preferred embodiment, the wiring assembly 3 includes two terminals 31 for connecting power lines, and two metal parts 4 are formed by extending from the two terminals 31 respectively.

[0044] The terminal block 31 is made of metal and is used to connect the power cord and establish a conductive connection between the power cord and the terminal block 31. It is typically secured with screws. In this design, the metal component 4 extends from the terminal block 31, meaning that the metal component 4 and the terminal block 31 are integrally formed from the same material. This design reduces the steps of connecting the metal component 4 to the terminal block 31; only the metal component 4 needs to be connected to the light-emitting component 2, increasing installation efficiency. (Refer to...) Figure 5 As shown.

[0045] The terminal block 31 is generally formed by cutting a metal plate. After the metal part 4 is formed, it only needs to be bent to be used to connect with the light-emitting component 2. Therefore, the entire indicator light has the advantage of high production efficiency to a certain extent.

[0046] First, it should be noted that the light-emitting component 2 is generally composed of a circuit board 21 and LED beads. The circuit board 21 is equipped with electronic components to work with the LED beads so that they can be safely lit.

[0047] Two connection methods between the metal part 4 and the light-emitting component 2 are also provided below:

[0048] 1. The metal part 4 is connected to the circuit board 21 of the light-emitting component 2 by soldering. The circuit board 21 has a reserved pin hole, through which the end of the metal part 4 is inserted and soldered to the circuit board 21.

[0049] 2. A socket, such as a female connector, is pre-soldered on the circuit board 21 of the light-emitting component 2 for pin insertion. When making an electrical connection between the metal part 4 and the circuit board 21, the metal part 4 can be inserted into the socket, and the metal part 4 can be fixed and electrically connected through this insertion method.

[0050] In addition, refer to Figure 2 , 3 As shown in Figures 5 and 7, in order to facilitate quick engagement between the metal part 4 and the contact part 51 and to make the conductive contact more stable, the contact part 51 has a clamp structure and is used for inserting and clamping the metal part 4 to form a conductive contact.

[0051] By using the contact element 51 with a clip structure, the contact element 51 and the metal part 4 can be clamped together, rather than just being held together by elasticity.

[0052] Based on the above structure, when the anti-interference accessory 5 is installed on the housing 1, the contact 51 is first aligned with the metal part 4, and then the anti-interference accessory 5 is installed on the housing 1. As the anti-interference accessory 5 approaches and is installed on the housing 1, the contact 51 will move toward the metal part 4, and the metal part 4 will enter the clamp structure and be clamped by the clamp structure.

[0053] In this design, the hardness of the metal part 4 is required to a certain extent, so a metal sheet or copper wire is preferred. Of course, the specific choice can be changed by those skilled in the art as needed.

[0054] Specific references Figure 5 and 7 As shown, the contact 51 is formed by bending a conductive metal sheet to form a clip structure, and the end of the clip structure corresponding to the anti-interference accessory 5 is raised to form an opening for inserting the metal part 4. The opening forms a guide slope 52 through the raised clip structure to guide the metal part 4 into the clip structure and clamp it.

[0055] The method of forming a clamp structure by bending the conductive metal part 4 is convenient and efficient. After bending the metal part 4, different angles can be formed by changing the degree of bending. The angle is controlled by changing the bending angle of one end of the clamp structure corresponding to the anti-interference accessory 5. The opening formed by the bending of this end guides the metal part 4 into the clamp structure and clamps it, making the fit between the metal part 4 and the clamp structure easier and thus increasing the ease of installation.

[0056] Since the clamp structure requires a certain force to open its opening, when the contact 51 and the metal part 4 are clamped together, a certain contact force is first required to allow the metal part 4 to open the opening of the clamp structure and to continuously allow the metal part 4 to enter the clamp structure so that the clamp structure can clamp the metal part 4.

[0057] For this purpose, the housing 1 is also provided with a slot 6 for the metal part 4 to pass through, at least a part of the metal part 4 is located in the slot 6, and the slot 6 is used to limit the swing or deformation of the metal part 4 or to position the metal part 4.

[0058] The slot 6 limits the movement of the metal part 4, providing support and reducing deformation. This ensures a more stable fit between the metal part 4 and the contact part 51, preventing bending due to pressure from the contact part 51, which could weaken the fit or even prevent clamping. The slot 6 also positions the metal part 4 stably along the path of the contact part 51, facilitating the clamping action between them.

[0059] In addition, refer to Figure 3 , 5 As shown in Figures 6 and 7, the width of a section of the metal part 4 corresponding to the wiring assembly 3 is greater than the width of a section of the metal part 4 corresponding to the light-emitting assembly 2, and the position of the contact 51 corresponds to the position with the larger width of the metal part 4, and the position of the slot 6 also corresponds to the position with the larger width.

[0060] The metal part 4 is wider at the position corresponding to the contact 51, providing higher strength and making it less prone to deformation. Although the section of the metal part 4 corresponding to the light-emitting component 2 is narrower, the slot 6 corresponds to the wider section, preventing deformation of the metal part 4 when pressed by the contact 51. This avoids the weaker strength of the narrower section of the metal part 4 affecting the fit between the contact 51 and the metal part 4. Furthermore, it saves material, and the narrower section facilitates connection to the circuit board 21 of the light-emitting component 2.

[0061] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
