Description

Technical Field

[0001] The utility model relates to a driving power supply for an LED lamp, in particular to an LED driving power supply with expandable functions. Background Art

[0002] LED is a semiconductor device that can convert electrical energy into light energy. It is widely used in various lighting fixtures due to its high efficiency, low energy consumption and long life. These lamps have become indispensable lighting appliances in people's lives and work. Tri-proof lamps are a kind of lamps that use LED as light source. Since tri-proof lamps have the advantages of waterproof, dustproof and anti-corrosion, the environment in which tri-proof lamps are generally used is also relatively harsh. They are usually used in places with strong corrosion, high dust and high humidity.

[0003] Existing tri-proof lamps generally include a lamp holder, a lampshade, a light source board disposed between the lamp holder and the lampshade, a heat dissipation mechanism disposed between the light source board and the lamp holder, and a driving power module is installed on the side of the heat dissipation mechanism facing the light source board. For example, the Chinese utility model patent "A tri-proof lamp" with patent number ZL201720337741.8 (publication number CN206817233U), the Chinese utility model patent "A tri-proof lamp with a heat dissipation device" with patent number ZL202321891906.8 (publication number CN220379618U), and the Chinese utility model patent "A tri-proof lamp with a heat dissipation device" with patent number ZL202321522604.3 (publication number CN220017174U) all disclose a similar structure.

[0004] With the development of technology, the demand for tri-proof lamps has increased, such as dimming, power adjustment, or wireless intelligent driving. This requires the addition of different functional modules, and the terminals of various modules need to be connected to the driver power supply. However, the existing old tri-proof lamps have fixed driver power supply models. If you want to add functions, you need to replace the driver power supply. The old driver power supply does not have the corresponding port, and the latest multi-functional driver power supply is large in size and cannot be installed in the old tri-proof lamps. In other words, the old tri-proof lamps cannot be modified, and the entire lamp can only be replaced, which greatly increases the modification cost.

[0005] In summary, how to transform old tri-proof lamps into tri-proof lamps with extended functions is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a LED driving power supply with a reasonable structure and expandable functions in view of the above-mentioned existing technical status, which makes it possible for old three-proof lamps to be transformed into three-proof lamps with expanded functions.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: an LED driving power supply with expandable functions, including a base, an upper cover, and a circuit board, wherein the circuit board is fixed on the base, the upper cover is installed on the base and covers the circuit board, and the circuit board is provided with wiring terminals; it is characterized in that: at least one of the left and right ends of the circuit board passes through the upper cover from one side, and the circuit board passing through the upper cover is provided with only one functional interface for plugging in an external module.

Two interfaces with different functions can realize different extended functions according to needs, wherein the DIP functional interface can realize DIP power adjustment (>2 power levels) and DIP CCT (>2 CCT), and the auxiliary source functional interface can realize PWM dimming, 0 / 1-10V dimming, microwave sensing, NFC functions, etc.

[0009] Preferably, the DIP function interface and the auxiliary source function interface are both located on the same side of the circuit board and are arranged side by side. In this way, the expansion function modules are all on the same side, which is convenient for assembly. Of course, this does not mean that they cannot be placed on both sides.

[0010] As an improvement, the above-mentioned wiring terminals are arranged on the circuit board passing through the upper cover, so that the wiring terminals can be exposed outside the upper cover, which is more convenient for wiring.

[0011] Preferably, both left and right ends of the circuit board pass through the upper cover, and there are two wiring terminals. Two wiring terminals mean that wiring can be performed on both sides, which makes the operation more user-friendly.

[0012] Further improvement, the base and the upper cover are both formed by bending metal plates, the base has a bottom surface, a front lower side wall and a rear lower side wall located on the front and rear sides of the bottom and folded upward, and two fixing holes are respectively opened on the left and right sides of the bottom surface; the upper cover has a top surface, a front upper side wall and a rear upper side wall located on the front and rear sides of the top surface and folded downward, and a left upper side wall and a right lower side wall located on the left and right sides of the top surface, and a gap is formed between the left upper side wall and the right lower side wall and the bottom surface for the circuit board to pass through; the circuit board is restricted on the bottom surface of the base, and the front upper side wall and the front lower side wall, and the rear upper side wall and the rear lower side wall are connected together by snapping. The base and the upper cover are made of metal material to facilitate heat dissipation; the lower cover is in a U-shaped groove shape as a whole, has no left and right side walls, and has a strip-shaped installation groove, which is convenient for assembling the circuit board; the base and the upper cover are connected to each other by snapping through the front and rear side walls, and when assembling, only the upper cover needs to be buckled into the base from top to bottom to complete the installation, which is convenient to install.

[0013] In order to facilitate the mutual snapping of the upper cover and the base, the top of the front lower side wall has an inwardly arched front guide surface, and the front lower side wall is provided with a plurality of front snap holes spaced apart from each other on the left and right sides; the top of the rear lower side wall has an inwardly arched rear guide surface, and the rear lower side wall is provided with a plurality of rear snap holes spaced apart from each other on the left and right sides; the inner wall of the front upper side wall is stamped with a plurality of front snap points spaced apart from each other on the left and right sides, and the inner wall of the rear upper side wall is stamped with a plurality of rear snap points spaced apart from each other on the left and right sides; the outer wall surface of the front lower side wall is fitted with the inner wall surface of the front upper side wall, and the front snap points are correspondingly snapped into the front snap holes; the outer wall surface of the rear lower side wall is fitted with the inner wall surface of the rear upper side wall, and the rear snap points are correspondingly snapped into the rear snap holes. The setting of the guide surface makes it more convenient to snap the pressure cover onto the base from top to bottom, and the snapping process can squeeze the front and rear lower side walls, which is conducive to the snap points snapping into the snap holes, and the two lower side walls are located between the two upper side walls and covered by the top surface of the upper cover, so that the overall product is more integrated.

[0014] As an improvement, a plurality of raised support points are formed on the bottom surface, the circuit board is placed on the support points, and the circuit board is fixed to one of the support points by a screw. The support points suspend the circuit board to prevent the circuit board from being attached to the bottom surface of the base as a whole, thus protecting the circuit board and providing heat insulation.

[0015] Compared with the prior art, the advantages of the present invention are: at least one of the left and right ends of the circuit board passes through the upper cover from one side, and the circuit board passing through the upper cover is provided with only one functional interface for plugging in an external module. The corresponding external modules can be adapted according to the different needs of customers, and the installation is simple and the functions are diverse. It is suitable for use in lamps with many requirements and limited space. With the expansion function, the lamp materials can be reduced, and the cost can be reduced. Compared with the old driving power supply of the applicant, only the circuit board is improved, and the overall appearance and dimensions remain unchanged, which is conducive to the renewal of the products sold by the applicant.
