As shown in Figures 1 and 2, the LED light engine 100 includes a multi-pass vertical tensioning card interface and an LED light source module. The multi-pass vertical tensioning card interface is generally circular. The card interface includes: a base stacked on the LED light source module, at least two bayonet 101 on the base, an end face spring 102 on a concave plane in the base, and a power supply and a telecommunications at the center of the base Four concentric sockets 103.

Sectional view of the mounting and card interface mounts.

As shown in Figures 3 and 4, the card interface mount 200 is generally circular in shape and includes a circular outer cover including a circular bottom surface and a cylindrical side surface; formed in a circular outer cover At least two grooves T plane 201 on the inner side surface, each groove T plane has an opening at one end, the other end has a limiting protrusion 204; a four concentric plug 203 located at the center of the circular outer cover; And a face spring reed boss 202 formed in the circular outer casing and between the groove T plane and the four concentric plugs. The circular outer cover, the four concentric plugs, and the end reed mating bosses are the same mechanical center. In one embodiment, the card interface mount includes three groove T-planes with a central angle between the planes of the two T-planes being 120 degrees. In another embodiment, a retaining projection 205 is provided at the open end of each groove T plane for preventing the bayonet of the card interface from slipping out of the recess.

The card interface mount 200 has three correspondences with the structure of the card interface of the LED light engine in the mounting structure. They are: (1) the groove T plane 201, and (2) the end leaf reed docking station 202. And (3) power and telecommunications quad concentric plug 203.

When the LED light engine 100 including the card interface according to the present application is docked into position with the card interface mount 200, each of the bayonet ports 101 on the LED light engine card interface and each gap on the card interface mount are respectively One by one, the four concentric sockets 103, which are located at the center of the LED light engine card interface, are also docked with the four concentric plugs 203 at the center of the card interface mount. At this time, the operator's eye observation and the hand touch are simultaneously used, which is similar to the plug-in power supply of the household appliance in daily life. Once the bayonet 101 on the LED light engine card interface is in place and the center plug 203 and the center jack 103 are simultaneously aligned, the operator advances the LED light engine 100 toward the card interface mount 200 and stops propelling when reaching the bottom. When the card interface of the LED light engine is inserted into the card interface mount 200, the end surface reed 102 in the LED light engine card interface and the end surface reed in the card interface mount 200 are convexly coupled. The table 202 contacts and is reacted by the plane of the docking boss, and the operator feels that the end leaf spring 102 is pressed by the force. When the card interface of the LED light engine reaches the bottom of the card interface mount 200, the LED light engine is energized, with the LED array 105 illuminated. At this point, the operator can rotate the LED light engine to the left or right, for example, by 55 degrees to 70 degrees, so that the bayonet 101 on the LED light engine card interface is screwed into the groove on the card interface mount 200. The T-plane 201, until the bayonet 101 on the LED light engine card interface contacts the limit bump 204, the operator can release the hand. This installation operation can be done with one hand for a 4-inch LED light engine and more suitable for a larger LED light engine with both hands. When the external force is removed, the bayonet 101 on the LED light engine card interface is placed in the card interface mount 200 by the end leaf spring 102. As shown in Fig. 5, the end leaf spring 102 is pressed, and the bayonet 101 is in close contact with the groove T plane 201 of the card interface mount. The above is the entire process in which the LED light engine 100 is mounted to the card interface mount 200.

When the LED light engine 100 needs to be detached from the card interface mount 200, the operator can hold the LED light engine 100 with one hand or both hands, and place the LED light engine 100 along the axial direction of the card interface mount 200 with appropriate thrust. Squeezing toward the card interface mount 200, the end spring in the card interface mount is compressed, and the LED light engine is rotated to the right or left, for example, rotated 55 degrees to 70 degrees, and the card interface 101 is reached at the card interface installation. At the notch of the seat, the bayonet 101 is disengaged by the tension of the end face spring, so that the LED light engine 100 is removed from the card interface mount 200.

FIG. 6 shows a cross-sectional view and a side view of a four concentric plug 203 and a socket 103. As shown in FIG. 6, the four concentric plugs 203 comprise concentric four-turn cylindrical copper skin, wherein two layers of copper skin of the outer ring form a double path, and two layers of copper of the inner ring form another double path, thereby realizing LED Multiple channels of light engines. The plug 203 also includes mounting threads 602 for mounting to the card interface mount 200, and solder legs 603 for connection to external power and communication lines.

Further, the four concentric sockets 103 include two concentric annular accommodation spaces. The inner ring accommodating space is for accommodating two layers of copper skin of the inner ring of the plug 203, and the copper pin 604 and the elastic piece 605 in the inner ring accommodating space are respectively in contact with the two layers of copper skin of the inner ring of the plug 203. The outer ring receiving space is for receiving two layers of copper skin of the outer ring of the plug 203, and a pair of elastic pieces 605 in the outer ring receiving space are respectively in contact with the two layers of copper skin of the outer ring of the plug 203. The socket also has a solder fillet 606 for connection to an illumination, power supply, and/or control module in the LED light engine. In one embodiment, the outer diameter of the socket is 22.5 mm. The connection of the LED light engine to external power and communication lines is achieved by four concentric plugs and sockets.

The following is an analysis of the safety and reliability of the docking installation of the card light interface of the LED light engine and the card interface mount. Due to the bayonet 101 on the LED light engine card interface and the recess on the card interface mount and the four concentric receptacles 103 and plugs 203, their geometry and fit are based on the geometrical axis of the card interface mount As a reference, the mechanical movement of the four concentric receptacles 103 and the bayonet 101 is consistent, so that the electrical wiring is reliable. The pressure of the end leaf spring 102 allows the bayonet 101 to be securely and securely seated in the recess, such as a bayonet fit, even when mounted on a moving vehicle, the vehicle's vertical vibration or rotational inertia (because of rotational motion and vertical vibration or motion often It is impossible to separate the bayonet on the LED light engine card interface from the card interface mount.
