[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 6 The present invention provides an interchangeable module lighting fixture as follows: A luminaire with interchangeable modular lighting mainly includes a luminaire main unit 100 and an optical module 200. The luminaire main unit 100 consists of a lamp housing and a driving power supply 140 disposed within the lamp housing. The lamp housing further includes a lamp holder 110 and a lamp cover 120 that engages with the lamp holder 110. On the inner side of the lamp holder 110 facing the lamp cover 120, a standardized module interface is provided, which includes at least one set of electrical connection terminals.

[0022] The optical module 200 is an independent unit integrating a light source and optical components. The light source is specifically an LED board, and the optical components include lenses or reflectors. The optical module 200 is equipped with a connector that matches the module interface. During installation, the optical module 200 is aligned with the mounting position within the lamp holder 110, aligning its connector with the terminals of the module interface, and then secured to the lamp holder 110 using screws or by pressing the lamp cover 120. In this way, the optical module 200 achieves both mechanical connection and electrical connection with the luminaire main unit 100.

[0023] When a change in lighting effect is needed, such as switching from street lighting to plaza lighting, simply open the lamp cover 120, remove the original optical module 200, and replace it with another optical module 200 that has a different light distribution curve, such as a different spot shape and beam angle. This allows a single lighting platform to adapt to various lighting scenarios by replacing different optical modules 200, achieving versatility and flexibility.

[0024] Furthermore, the luminaire main unit 100 is not directly fixed, but is mounted on a base 400 via a rotating fixing structure. The base 400 is used to fix it to the lamp post 130 or the mounting surface. The rotating fixing structure includes a turntable connected to the bottom of the luminaire main unit 100, and a bearing seat connected to the base 400 and allowing the turntable to rotate thereon.

[0025] During use, installers can manually rotate the entire luminaire main unit 100, allowing it to rotate around its vertical axis in the horizontal plane, thus precisely adjusting the luminaire's illumination direction. Once the predetermined angle is reached, tightening the set screws on the side of the bearing housing locks the turntable using friction, preventing it from rotating on its own. This angle adjustment function, combined with the module interchangeability function, allows the luminaire to flexibly adapt to site requirements after installation, further enhancing its practicality. Specifically, when an asymmetrical optical module 200 is installed, the illumination area can be adjusted by rotating the luminaire.

[0026] Furthermore, a lamp post 130 with an open lower end is fixedly connected to the bottom of the lamp main unit 100. A fixing post protrudes upward on the base 400. During installation, the lower end of the lamp post 130 is fitted onto the fixing post, allowing the lamp post 130 to rotate around the fixing post.

[0027] To achieve angle fixation, multiple threaded holes are evenly spaced along the circumference on the side wall of the lamp post 130. The outer circumferential wall of the fixing post is a smooth cylindrical surface. Locking screws 300 corresponding to the number of threaded holes are provided. When angle adjustment is needed, all locking screws 300 are loosened, allowing free rotation of the lamp post 130 and the lamp holder 100 above it. Once the angle is adjusted, all locking screws 300 are tightened inwards until their tips firmly press against the outer circumferential wall of the fixing post. The frictional force generated by the large positive pressure of the screws effectively prevents relative rotation between the lamp post 130 and the fixing post, achieving a secure angle fixation. This structure is simple to manufacture, inexpensive, and provides strong and reliable locking force.

[0028] Furthermore, a female connector is fixedly installed on the lamp holder 110 of the luminaire main unit 100, which is connected to the output terminal of the drive power supply 140 via a wire. Correspondingly, a male connector that matches the aforementioned female connector is installed on the back of each optical module 200, which is connected to the light source inside the module via a wire.

[0029] When the optical module 200 is installed into the lamp holder 110, the male connector precisely inserts into the female connector, enabling circuit continuity. This plug-in connection method makes replacing the optical module 200 as simple and quick as changing a household appliance plug, forming the basis for rapid interchangeability.

[0030] Furthermore, based on the electrical connection, a quick mechanical locking device is needed to secure the optical module 200. The first option is a magnetic structure: a strong magnet is embedded at a specific position on the mounting surface of the lamp holder 110, and a metal sheet or a reverse magnet is embedded at a corresponding position on the base 400 of the optical module 200, relying on magnetic attraction for fixation. The second option is a knob screw: a through hole is made on the side of the lamp holder 110, and a screw with a large hand-tightening knob is installed; rotating the knob tightens the top of the screw against the side of the optical module 200 for fixation. The third option is a snap-fit ​​structure: elastic hooks are designed on both sides of the optical module 200, and slots are designed on the inner wall of the lamp holder 110; during installation, pressing down on the module causes the hooks to slide into the slots and lock. These devices are all designed to allow locking and unlocking without tools or with only simple manual operation.

[0031] Furthermore, to prevent wide-beam modules suitable for main roads from being mistakenly installed in locations requiring pedestrian street light-cutting modules, or vice versa, this embodiment incorporates a keyway structure on the module interface to prevent mis-insertion. Specifically, a raised positioning key is designed on the plastic housing of the female connector of the luminaire host 100; while a positioning groove matching the shape and position of the positioning key is formed on the housing of the male connector of the optical module 200.

[0032] The male connector can only be successfully inserted into the female connector when the positioning slot on an optical module 200 is perfectly aligned with the positioning key on the main unit. If an incorrect type of module is attempted to be installed, whose positioning slot is in a different position, the positioning key will physically block the insertion, thus effectively preventing misinsertion and ensuring the accuracy of the lighting design.

[0033] Furthermore, the driver power supply 140 within the lighting unit 100 is an intelligent driver circuit. Each optical module 200's male connector integrates either a specific identification resistor or a small chip storing the module type code. When an optical module 200 is connected, the intelligent driver circuit reads the resistance value of the identification resistor or the code within the chip to determine whether the currently connected module is a "wide beam module" or an "asymmetric cutoff module," etc.

[0034] The drive circuit then automatically queries its built-in database to retrieve the optimal operating current and power parameters that match the module type, and drives the light source accordingly. For example, a wide-beam module may require higher power to meet illuminance requirements, while a cut-off module may operate at slightly lower power to extend its lifespan and save energy. This achieves plug-and-play intelligent power management.

[0035] Furthermore, the optical module 200 comes in at least two types. The first type is a wide-beam symmetrical light distribution module suitable for main road lighting. Its optical system is designed to produce a wide and uniformly symmetrical light spot in both the longitudinal and transverse directions of the road, ensuring uniform overall brightness of the road surface. The second type is an asymmetric cut-off light distribution module suitable for pedestrian streets, sidewalks, and other areas. Its optical system is specially designed to precisely project most of the light onto the area requiring illumination, such as the road surface, while strictly limiting spillage light towards pedestrians' lines of sight and residential windows, effectively avoiding glare interference. Users can choose the appropriate module from these two or more types for installation based on their actual application scenario.

[0036] Furthermore, the lamp housing of the lamp main unit 100 is composed of a lamp holder 110 and a lamp cover 120. After the optical module 200 is installed, gaps of several millimeters are reserved between its top and the inner wall of the lamp cover 120, and between its bottom and the inner wall of the lamp holder 110, forming heat dissipation gaps. These gaps constitute channels for natural air convection, which helps to dissipate the heat generated by the optical module 200 during operation into the surrounding air in a timely manner, avoiding heat accumulation that could lead to light decay or damage.

[0037] Specifically, to ensure that the heat dissipation interval can be formed stably and consistently, in this embodiment, two support frames are provided on the mounting plane of the optical module 200. The optical module 200 is fixed to the support frames with fixing screws. In other embodiments, three triangularly distributed raised pads 111 are provided on the mounting plane of the lamp holder 110 used to support the optical module 200. These pads 111 can be bosses integrally formed with the lamp holder 110, or they can be heat-resistant silicone pads installed later. The optical module 200 is placed on these three pads 111, thereby naturally forming a predetermined heat dissipation channel between its bottom and the mounting plane of the lamp holder 110. This design ensures both the stability of the support and optimizes the heat dissipation effect.

[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
