Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp with a replaceable light source component. Background Art

[0002] Existing lamps generally include a lamp socket and a light source component. The light source component such as a lamp tube or a light bulb is installed on a wall or the like through the lamp socket, and then an external power supply is connected to use. The light source components of some lamps are fixedly installed on the lamp socket. When the light source component is damaged, the entire lamp needs to be discarded, resulting in waste. In response to this, some manufacturers detachably install the light source component on the lamp socket. When the light source component is damaged, only the light source component needs to be removed from the lamp socket for replacement, and the lamp socket can continue to be used, reducing waste.

[0003] It can be understood that when in use, the light source component is powered on. When replacing the light source component, it is necessary to ensure that the lamp is in a powered-off state. If the construction worker forgets to cut off the power and disassembles and installs the light source component while it is powered on, it is easy to cause an electric shock accident, bringing great risks to the personal safety of the construction worker. Summary of the Utility Model

[0038] Refer to Figure 1 、 Figure 2 and Figure 3 According to

[0039] In this embodiment, the lamp with a replaceable light source component includes a base 200, a circuit structure, a lamp shade 100, and a light source component. Among them, the base 200 is provided with a light-emitting cavity and a wiring cavity, the light-emitting cavity is communicated with the wiring cavity, the light-emitting cavity is used for installing the light source component, and the wiring cavity is used for arranging the circuit structure. The light-emitting cavity has a light-emitting opening, the lamp shade 100 is made of an insulating and light-transmitting material, the lamp shade 100 is detachably connected to the seat body 210, when the lamp shade 100 is connected to the seat body 210, the lamp shade 100 can cover the light-emitting opening, the lamp shade 100 plays a protective role for the light source component, improving the safety of the light source component during use, and the light emitted by the light source component located in the light-emitting cavity can shine out through the lamp shade 100 to achieve the lighting effect.

[0040] It should be noted that the circuit structure of this embodiment includes two power connection pieces 500, two conductive pieces 110 are connected to the lamp shade 100, and two power connection parts are provided on the light source component. When the lamp shade 100 is connected to the base 200, the two conductive pieces 110 are respectively in contact with the two power connection parts of the light source component, and the power connection pieces 500 extend from the light-emitting cavity to the wiring cavity, so that the two conductive pieces 110 are respectively connected to the two power connection pieces 500 of the circuit structure. Refer toFigure 4 and Figure 6 。

[0041] It can be understood that through the two conductive sheets 110 connected to the lampshade 100, the two power connection parts of the light source component can be respectively connected and conduct electricity with the two conductive sheets 500 in the circuit structure, so that the light source component is electrically connected to the circuit structure, and the circuit structure supplies power to the light source component, enabling the light source component to be used normally.

[0042] When the lampshade 100 is detached from the base 200, the conductive sheet 110 is disconnected from the power connection part of the light source component and the conductive sheet 500 of the circuit structure, so that the power connection part of the light source component is disconnected from the conductive sheet 500 of the circuit structure, and the circuit structure does not supply power to the light source component. When the light source component needs to be replaced, the lampshade 100 needs to be separated from the base 200 first to open the light-emitting cavity to take out the light source component. Therefore, when the construction personnel come into contact with the light source component, the light source component is already in a power-off state, thus avoiding the occurrence of electric shock accidents and improving the safety of installation and maintenance.

[0043] In this embodiment, the front side, rear side, and upper side of the light-emitting cavity are all light-emitting openings. The range of light irradiation of the light source component is larger, and it can increase the surface area of the lampshade 100, which is more conducive to the construction personnel to disassemble the lampshade 100 from the base 200.

[0044] In this embodiment, referring to Figure 4 and Figure 5 , two first hooks 120 are respectively arranged at the left and right ends of the lampshade 100. The two first hooks 120 on the same side of the lampshade 100 are arranged front and back. The left and right side walls of the light-emitting cavity are respectively provided with upward-opening slots 211, and second hooks 212 are respectively arranged on the front and rear slot walls of the slots 211. When the lampshade 100 covers the light-emitting opening from top to bottom, the two first hooks 120 at the left end of the lampshade 100 enter the slots 211 on the left side wall of the light-emitting cavity and are engaged with the second hooks 212 of the slots 211; the two first hooks 120 at the right end of the lampshade 100 enter the slots 211 on the right side wall of the light-emitting cavity and are engaged with the second hooks 212 of the slots 211. Through the above steps, the connection between the lampshade 100 and the base 200 can be realized. When the lampshade 100 needs to be detached from the base 200, an upward pulling force is applied to the lampshade 100 to separate the first hook 120 from the second hook 212 and disengage from the slot 211, and the disassembly of the lampshade 100 can be realized.

[0045] In this embodiment, the hook portions of the first hooks 120 on the same side of the lamp cover 100 face each other, and the upper and lower surfaces of the hook portions are both inclined surfaces; the hook portions of the second hooks 212 in the same card slot 211 of the light-emitting cavity face each other, and the upper and lower surfaces of the hook portions are both inclined surfaces. During clamping, the first hook 120 is located between the two second hooks 212 in the same card slot 211. When the lamp cover 100 is pushed downward, the lower surface of the hook portion of the first hook 120 contacts the upper surface of the hook portion of the second hook 212, and the second hook 212 can push the hook portions of the two first hooks 120 on the same side of the lamp cover 100 to approach each other, so that the first hook 120 can more easily enter between the two second hooks 212 in the same card slot 211 until the hook portion of the first hook 120 reaches the lower side of the hook portion of the second hook 212. When disassembling the lamp cover 100, when the lamp cover 100 is pulled upward, the upper surface of the hook portion of the first hook 120 contacts the lower surface of the hook portion of the second hook 212, and the second hook 212 can push the hook portions of the two first hooks 120 on the same side of the lamp cover 100 to approach each other, so that the first hook 120 can more easily escape between the two second hooks 212 in the same card slot 211.

[0046] In this embodiment, referring to Figure 6 , each conductive sheet 110 is respectively provided with two power connection pins 113, and the power connection pins 113 extend downward. Each connection sheet 500 is respectively provided with a power connection groove 510, and the opposite two groove walls of the power connection groove 510 are elastic sheets 520. When the lamp cover 100 is installed on the base 200, the power connection pins 113 are inserted downward into the power connection groove 510, and the two opposite groove walls of the power connection groove 510 clamp the power connection pins 113, so as to improve the connection stability between the conductive sheet 110 and the connection sheet 500, ensure stable power connection during power use, and enable the light source component to be used normally.

[0047] In this embodiment, both the conductive sheet 110 and the connection sheet 500 are made of copper material, which has good electrical conductivity, low cost, and good ductility. It can be understood that the conductive sheet 110 and the connection sheet 500 can also be made of other conductive materials, such as other metal materials like silver and aluminum.

[0048] In some embodiments, the light source component is a lamp board 300, such as an LED board. The lamp board 300 includes structures such as lamp beads and a substrate. The substrate is plate-shaped, and the lamp beads are arranged towards the light-emitting port. After the lamp beads are powered on, they can emit light. It can be understood that the lamp board 300 is generally designed by the manufacturer according to the user's needs. Since it is not a standard part, the lamp boards 300 produced by different manufacturers may be different, and the positions of the power connection parts on the lamp board 300 may be different. It can be understood that the conductive sheet 110 connected to the lamp shade 100 needs to correspond to the position of the power connection part on the lamp board 300. When the lamp board 300 is damaged, the user needs to select a lamp board 300 of the corresponding model from the original manufacturer for replacement. However, when the corresponding lamp board 300 is out of production or out of stock, etc., it is difficult for the user to find a suitable lamp board 300 for replacement, and they can only discard the entire lamp with a replaceable light source component, resulting in waste.

[0049] In some embodiments, the light source component is a lamp tube 400. The main body of the lamp tube 400 is cylindrical, and the power connection parts of the lamp tube 400 are arranged at the left and right ends. It can be understood that the lamp tube 400 is a standard part, which is designed according to the standard size. When replacing, it can be replaced according to the corresponding size, and it is easy for the user to find a suitable lamp tube 400 for replacement. However, the light efficiency of the lamp tube 400 is single, and the aesthetics is not as good as that of the lamp board 300 designed according to the user's needs.

[0050] In this embodiment, both the lamp tube 400 and the lamp board 300 can be used as light source components. A first pin 111 and a second pin 112 are respectively arranged on each conductive sheet 110. Among them, the first pin 111 is used to connect the power connection part of the lamp tube 400, and the second pin 112 is used to connect the power connection part of the lamp board 300, which can realize the replacement and use between standard parts and non-standard parts. Among them, Figure 2 FIG. is a schematic diagram of using the lamp board 300 as a light source component, Figure 3 FIG. is a schematic diagram of using the lamp tube 400 as a light source component.

[0051] It can be understood that since the conductive sheet 110 in this embodiment is not only provided with the second pin 112 for connecting the lamp board 300, but also provided with the first pin 111 for connecting the lamp tube 400, the conductive sheet 110 on the lamp shade 100 can not only be electrically connected to the lamp board 300, but also be electrically connected to the lamp tube 400. When the user can find a suitable lamp board 300 for replacement, use the appropriate lamp board 300 for replacement to meet the rich light efficiency requirements; and when the user fails to find a suitable lamp board 300 for replacement, the standard-sized lamp tube 400 can be used instead. Other performance-good components of the lamp with a replaceable light source component do not need to be discarded. After replacing the lamp board 300 of the lamp with a replaceable light source component with the lamp tube 400, it can still continue to play the role of lighting.

[0052] In some embodiments, the circuit structure further includes a driving module 700 and a socket 800. The power connection piece 500 is electrically connected to the driving module 700, and the socket 800 is electrically connected to the power connection piece 500. It can be understood that the lamp board 300 generally uses a base voltage and requires the driving module 700 to drive it; the lamp tube 400 is generally powered by a standard voltage.

[0053] In this embodiment, the socket 800 is a small European standard socket 800 with a voltage standard of 220V, which is generally used when the lamp tube 400 is used as a light source component.

[0054] In some embodiments, the circuit structure further includes a microswitch 242. The power connection piece 500 and the driving module 700 are electrically connected through the microswitch 242, and the power connection piece 500 and the socket 800 are also electrically connected through the microswitch 242. When the microswitch 242 is in the first state, the driving module 700 is electrically connected to the power connection piece 500, while the socket 800 is disconnected from the power connection piece 500; when the microswitch 242 is in the second state, the driving module 700 is disconnected from the power connection piece 500, while the socket 800 is electrically connected to the power connection piece 500.

[0055] It can be understood that the microswitch 242 is a contact mechanism with a small contact interval and a quick-acting mechanism, which performs a switching action with a specified stroke and a specified force, is covered with a housing, and has a driving rod on the outside. Inside the microswitch 242, there are fixed contacts respectively connected to the socket 800 and the driving module 700, and there is an actuating reed that can move. When an external force acts on the driving rod, the driving rod transmits the force to the internal actuating reed. When the actuating reed displaces to the critical point, an instantaneous action occurs, causing the moving contact at the end of the actuating reed to quickly connect with the fixed contact connected to the driving module 700 and quickly disconnect from the fixed contact connected to the socket 800, that is, in the first state, so that the driving module 700 is connected to the power connection piece 500, and the socket 800 is disconnected from the power connection piece 500. When the external force is removed, the acting force of the driving rod on the actuating reed disappears, and the moving contact at the end of the actuating reed quickly disconnects from the fixed contact connected to the driving module 700 and quickly connects to the fixed contact connected to the socket 800, that is, in the second state, so that the driving module 700 is disconnected from the power connection piece 500, and the socket 800 is electrically connected to the power connection piece 500.

[0056] In this embodiment, when the lamp board 300 is used as the light source component, the lamp board 300 contacts above the driving rod of the microswitch 242, and the second pin 112 presses above the lamp board 300, causing the lamp board 300 to press down the driving rod of the microswitch 242, so that the microswitch 242 is in the first state. The driving module 700 is electrically connected to the power connection piece 500, and the socket 800 is disconnected from the power connection piece 500. When the lamp tube 400 is used as the light source component, the lamp tube 400 is separated from the driving rod of the microswitch 242, so that the microswitch 242 is in the second state. The driving module 700 is powered off from the power connection piece 500, and the socket 800 is powered on to the power connection piece 500.

[0057] It can be understood that with such a setting, when replacing the lamp board 300 and the lamp tube 400, when installing the lamp tube 400, the circuit for driving the lamp board 300 is automatically disconnected, and the circuit for driving the lamp tube 400 is automatically turned on; when installing the lamp board 300, the circuit for driving the lamp board 300 is automatically turned on, and the circuit for driving the lamp tube 400 is automatically disconnected. The entire replacement process is simpler and faster, without the need to additionally modify the circuit structure for wiring, achieving plug-and-play.

[0058] In this embodiment, four microswitches 242 are provided. It can be understood that the microswitch 242 is an existing electrical component in the art, and those skilled in the art should be clear about its structure and principle.

[0059] In some embodiments, the circuit structure further includes a terminal block 600, and the terminal block 600 is used to realize the wiring of each electrical component of the circuit structure.

[0060] It can be understood that the setting of the terminal block 600 can more conveniently connect the wiring of components such as the driving module 700, the power connection piece 500, and the microswitch 242, so as to achieve the effect of electrical connection, which is more conducive to production and processing. Before the product leaves the factory, the electrical connection of electrical components such as the driving module 700, the power connection piece 500, and the microswitch 242 has been completed in advance through the terminal block 600, and there is no need to re-wire during use. When electrical components such as the driving module 700 and the microswitch 242 are damaged, the damaged electrical components can be detached from the circuit structure through the terminal block 600, which can more conveniently repair and replace the electrical components.

[0061] In this embodiment, third hooks 213 are respectively provided on the front and rear groove walls of the card slots 211 at the left and right end faces of the light-emitting cavity.
