Description

Technical Field

[0001] The present invention relates to the field of panel lights, and in particular to a modular panel light. Background Art

[0002] At present, panel lights have aesthetic effects such as simplicity and comfort in appearance. They are often used in various scenes that require long-term lighting, such as shopping malls, banks, hospitals, etc. They can not only form decorative structures such as ceilings, but also play a role in lighting.

[0003] The existing panel lights include a shell, a back panel and several PCB light boards. The shell is fixedly installed on one side of the back panel, the several PCB light boards are located between the shell and the back panel, and the several PCB light boards are fixedly installed on the back panel at intervals. The light boards are connected by wires; the PCB light board consists of a PCB board and four groups of SMD LED lamp beads and lenses.

[0004] Regarding the above-mentioned related technologies, when a group or a single LED lamp bead is damaged after being used for a period of time, the entire PCB lamp board needs to be replaced, which results in high maintenance costs. Summary of the invention

[0005] In order to reduce maintenance costs, the present application provides a modular panel light.

[0006] The present application provides a modular panel light, which adopts the following technical solution:

[0007] A modular panel light comprises a back plate and a shell installed on one side of the back plate, the shell being provided with a plurality of rows of mounting grooves, a PCB strip being fixedly installed at a position of the back plate corresponding to each row of the mounting grooves; a light-emitting module being installed in each mounting groove corresponding to the shell, the light-emitting module comprising a mounting shell detachably installed on the shell, a PCB board installed on the mounting shell, and a plurality of lamp beads electrically connected to the PCB board, the PCB board being electrically connected to the PCB strip.

[0008] By adopting the above technical solution, when a certain lamp bead is damaged, the mounting shell of the corresponding single light-emitting module is directly detached from the outer shell, and the PCB board and the PCB strip are disconnected, and the single light-emitting module can be removed and replaced. This structure does not need to replace all the light-emitting modules in the entire row of mounting slots, thereby reducing maintenance costs.

[0009] Preferably, the PCB strip is provided with elastic terminals at positions corresponding to the installation slots, and the elastic terminals are inserted into the installation slots; the PCB board is provided with a power-carrying electrode on one side facing the elastic terminal, and the elastic terminal abuts against the power-carrying electrode.

[0010] By adopting the above technical solution, when the light-emitting module is installed into the installation groove, the elastic terminal abuts against the powered motor, thereby achieving electrical connection between the PCB board and the PCB strip, forming a contact electrical connection without the need for wiring, making the installation of a single light-emitting module easier and improving the efficiency of disassembly and assembly.

[0011] Preferably, an elastic buckle is provided on one side of the mounting shell near the bottom of the mounting slot, and a through hole is provided on the shell at a position corresponding to the elastic buckle, and the elastic buckle is passed through the shell through the through hole and buckled on the PCB strip; an operating hole for pushing the elastic buckle to unlock is provided on the back panel at a position corresponding to the elastic buckle.

[0012] By adopting the above technical solution, when installing a single light-emitting module, the elastic buckle passes through the shell through the through hole and then buckles on the PCB strip; when the light-emitting module needs to be removed, it is only necessary to unlock it by operating the elastic buckle through the operating hole; during this process, there is no need to remove the shell or the back panel, which greatly improves the overall disassembly and assembly efficiency.

[0013] Preferably, the elastic buckle includes a connecting rod and a locking block, the PCB strip is provided with a locking hole, and the operating hole is provided at a position corresponding to the locking hole; one end of the connecting rod is elastically connected to the mounting shell, and the other end of the connecting rod is simultaneously penetrated through the shell, the PCB strip and the back plate through the through hole, the locking hole and the operating hole; the locking block is arranged at the connecting rod corresponding to the locking hole, and the locking block is locked to the side of the PCB strip away from the shell.

[0014] By adopting the above technical solution, when installing a single light-emitting module, the connecting rod is aligned with the through hole and inserted, and then the operator first moves the connecting rod through the operating hole to deform it, and when the locking block reaches the side of the PCB bar away from the shell, the connecting rod is released, so that the locking block can be locked on the side of the PCB bar away from the shell; at this time, the connecting rod also passes through the back plate, so when the light-emitting module needs to be disassembled later, the operator only needs to move the connecting rod on one side of the back plate to unlock it; the above structure is easy to operate and highly practical.

[0015] Preferably, a guide surface is provided on a side of the positioning block away from the PCB strip.

[0016] By adopting the above technical solution, when installing the light-emitting module, the operator only needs to press the light-emitting module, and abut the hole wall of the locking hole through the guide surface to drive the connecting rod to deform spontaneously, and finally complete the locking block to the side of the PCB strip away from the outer shell; this structure can further improve the installation efficiency of the light-emitting module.

[0017] Preferably, each of the mounting shells is provided with a pair of the elastic buckles, and the positioning blocks of the same pair of the elastic buckles are arranged to be away from each other.

[0018] By adopting the above technical solution, not only can the installation of a single light-emitting module be made more stable, but the locking blocks of the same pair of elastic buckles are designed to be arranged away from each other, so that when the operator disassembles the light-emitting module, the two connecting rods of the same pair of elastic buckles can be simultaneously pushed towards each other with two fingers to complete the unlocking, thereby improving the convenience of disassembly.

[0019] Preferably, the mounting shell is provided with a lens corresponding to each lamp bead position.

[0020] By adopting the above technical solution, the lamp beads can be protected without affecting the lighting of the lamp beads.

[0021] Preferably, a plurality of grooves are provided on a side of the back plate away from the housing.

[0022] By adopting the above technical solution, the overall strength of the panel light can be improved.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When a certain lamp bead is damaged, the installation shell of the corresponding single light-emitting module is directly removed from the outer shell, and the PCB board and the PCB strip are disconnected, and the single light-emitting module can be removed and replaced. This structure does not need to replace all the light-emitting modules in the entire row of installation slots, thereby reducing maintenance costs;

[0025] 2. The operator only needs to put the light-emitting module into the installation slot and press the light-emitting module until the elastic buckle is buckled to the PCB strip to complete the installation of a single light-emitting module; the two connecting rods of the same pair of elastic buckles can be simultaneously moved towards each other with two fingers to complete the unlocking; there is no need to remove the back panel and the shell, which is easy to operate.
