Description

Technical Field

[0001] The utility model relates to the technical field of lighting, and particularly relates to a lamp with a quick-press type and a flexible printed circuit board connection. Background Art

[0002] A lamp refers to an appliance that can transmit light, distribute, and change the light distribution of a light source, including all components required to fix and protect the light source except the light source itself, as well as the wiring accessories necessary for connecting to the power supply. There are many types of lamps, including but not limited to chandeliers, table lamps, wall lamps, ceiling lamps, downlights, spotlights, etc. Different types of lamps have different characteristics and uses, and can be selected according to different needs and scenarios. For example, chandeliers are suitable for installation in places with high ceilings such as living rooms and dining rooms, wall lamps are suitable for installation on walls such as bedrooms and corridors, ceiling lamps are suitable for installation in places with low ceilings such as bedrooms and living rooms, downlights are suitable for installation on the ceiling, and spotlights are suitable for accent lighting, etc. In addition, there is also an indispensable lamp in indoor lighting, that is, the cabinet lamp.

[0003] A cabinet lamp is a lamp installed inside a cabinet to provide lighting. It usually uses energy-saving light sources such as LEDs or fluorescent lamps, and can provide soft and uniform light to illuminate the inside of the cabinet, making it convenient for users to use when cooking, storing items, or looking for things. There are various installation methods for cabinet lamps, and one can choose built-in, external, inductive, or rechargeable types, etc. Among them, built-in cabinet lamps are usually installed inside the top plate or side plate of the cabinet, but traditional embedded cabinet lamps generally protrude outward when installed in flat recesses. Coupled with the need for a certain amount of space for wiring, the overall thickness of the lamp will be relatively thick, resulting in insufficient installation space. Forcibly installing the lamp will expose it outside the flat plate, thus affecting the overall beauty of the cabinet. In addition, the lamp generally has a 2-meter or a certain length of wire reserved. During installation, the wire may need to be cut short or lengthened according to the actual situation to connect with the power supply wire, which is inconvenient for installation and reduces the installation efficiency of workers; moreover, when the lamp needs to be replaced, the lamp and the wire need to be replaced simultaneously, which will incur a relatively high replacement cost. Summary of the Invention

[0004] The purpose of the utility model is to provide a lamp with a quick-press type and a flexible printed circuit board connection in view of the defects and deficiencies of the prior art and the above background art. The structure is simple and ingenious, which is extremely convenient for installing and replacing the light source, greatly improves the installation efficiency of workers, is more conducive to cost savings, the installation space required becomes thinner, the lamp is not exposed, making the inside of the cabinet more concise and beautiful, and enhancing the overall decorative effect.

[0005] To achieve the above object and solve the above problems, the technical solution adopted by the present utility model is: A lamp with a quick-press type and flexible printed circuit board connection, including a lamp body light source, a lamp holder, and a flexible printed circuit board.

The flexible printed circuit board is a printed circuit with multiple sets of positive and negative contacts made of a flexible insulating substrate. One end of it is electrically connected to the contact elastic sheet by pressing down and rotating the pressing piece of the lamp holder rear cover so that the positive and negative contacts of the flexible printed circuit board are tightly pressed, and the other end is connected to a wiring terminal or a power source.

[0006] After adopting the above structure, the present utility model realizes the quick-press type wiring of the lamp to connect to the power source by pressing and rotating the pressing piece of the lamp holder rear cover, so that the flexible printed circuit board printed with positive and negative contacts is tightly pressed and electrically connected to the contact elastic sheet. It is extremely convenient to install and replace the lamp, greatly improving the efficiency of workers installing the lamp. The present utility model uses a flexible printed circuit board to replace the original wire as a conductor. Multiple sets of positive and negative contacts are printed on the flexible printed circuit board, and the length can be intercepted according to actual needs. The lamp does not need to be pre-connected with wires, which is more conducive to cost saving, and also makes the installation space required for the lamp thinner. The lamp is not exposed, making the interior of the cabinet more concise and enhancing the overall beauty of the cabinet.

[0007] The present utility model can not only be used for lamps in cabinets, but also be applied to other lighting lamps such as ceiling lamps, downlights, and spotlights in different scenarios to achieve quick press-type wiring installation of the lamps.

The threaded column protruding from the lamp holder housing is installed with a positioning screw in the screw hole, with simple and fast operation and high installation efficiency.

[0010] Further, there are multiple protruding parts above the contact elastic sheet, and a pressing groove is reserved below the pressing piece.

[0011] After further adopting the above structure, a space for accommodating the deformation of the flexible printed circuit board is reserved in the pressing groove below the pressing piece of the present utility model. When the pressing piece presses the flexible printed circuit board, the convex part of the contact elastic piece presses against the positive and negative contacts of the flexible printed circuit board, and the flexible printed circuit board will undergo a certain deformation. The reserved space can prevent the convex part of the contact elastic piece from piercing through the flexible printed circuit board and avoid poor contact.

[0012] Further, the lamp body light source includes a lamp body face cover, a PCB aluminum lamp board, an aluminum heat sink, and a lamp body housing. The lamp body face cover is screwed and tightened with the lamp body housing. The PCB aluminum lamp board has electrode pins.
