At the same time, it also has a pluggable external module expansion interface in the socket, for example, it can be installed with microwave sensors, infrared sensors, light sensors, Bluetooth controllers, group controllers, WIFI controllers, Internet of Things controllers, smoke alarms, fire alarms, video monitors, air detectors, small emergency lighting modules, forced convection fan modules, etc. More practical functions can be achieved through secondary development of external modules.

[0076] The optical lens module C1-01 is a light distribution lens that integrates multiple lighting angle solutions. Its single lens part simultaneously includes two or more lighting angles, and each angle is equipped with a corresponding lighting LED (see the enlarged partial image B). The corresponding optical light distribution is achieved by controlling the DIP switch of the expansion socket to light up the LED at one angle or all LEDs at all angles (see DIP switch 3 - lighting angle adjustment in the enlarged partial image A).

[0077] The optical lens C1-02 is a light distribution lens integrated on an optical lens, which can change the light-emitting angle of the lamp.

[0078] The control signal input line C1-03 enables the lamp to be connected to an external control device for signal connection, and has the functions of controlling the switch, brightness, and dimming of the lamp, and reading the working status of the lamp.

[0079] The power input line C1-04 is connected to the mains power grid, and a switch, a protective device, etc. can be added to its front end, and the power supply of the lamp is transmitted from it.

[0080] The lamp body radiator C1-05 is the main assembly part of the lamp, which serves as the basic shell, heat dissipation, and external structure of the lamp.

[0081] The DIP switch 1 (Signal Mode) adjustment pin is connected to the control board inside the expansion socket. Adjusting the switch position controls the expansion socket's signal conversion mode (see the enlarged view of the detail - Figure A). Currently, there are multiple platforms for lighting control worldwide, including 0-10V control, DALI control, RS485, and other wired control methods. However, these signal modes are incompatible with each other. However, lamps equipped with expansion sockets are fully compatible with the current mainstream global control modes. Adjusting the DIP switch 1 (Signal Mode) to the appropriate position enables compatibility with the corresponding control signal. The expansion socket first receives external control signals, converts them, and then transmits control signals recognizable by the lamp for control purposes, such as turning the lamp on and off, adjusting the brightness, and reading the lamp's operating status.

[0082] The DIP code 2-light color adjustment, the code lead is connected to the control board inside the expansion socket, by toggling the code position, the light color of the lamp can be changed (see the partial - Figure A enlarged picture), when the code is in the 3000K gear, the 3000K LED is lit, when the code is in the 5000K gear, the 5000K LED is lit (see the partial - Figure B enlarged picture), when the code position is in the 4000K gear, the 3000K and 5000K LEDs are lit, when both LEDs are lit and the brightness is the same, a mixed midpoint color temperature of 400 will be generated. 0K, by adjusting the brightness difference of the two color temperature LEDs, a color temperature offset phenomenon will be generated, so that a variety of mixed color temperatures can be obtained. When the brightness of the 3000K LED is greater than the brightness of the 5000K LED, the mixed color temperature is less than the midpoint color temperature. On the contrary, when the brightness of the 5000K LED is greater than the brightness of the 3000K LED, the mixed color temperature is greater than the midpoint color temperature (see the color temperature mixing principle reference diagram). Based on this calculation, the full-range stepless color temperature adjustment of 3000~5000K can be obtained by brightness adjustment. Adding a brightness matching module to the interface can output any light matching ratio. The color temperatures shown are only for ease of understanding, and the maximum range can be 1~10000K. The shape of the LED shown can also be circular, oval, square, bar, or special-shaped. The placement of the LED can be horizontal splicing, vertical splicing, X-staggered, axis-surrounding, linear diffusion, etc. Under the condition of complying with the basic working logic of the present invention, color temperature adjustment can be achieved.

[0083] The DIP code 3-lighting angle adjustment, the code lead angle is connected to the control board inside the expansion socket, and the light emitting angle of the lamp can be changed by toggling the code position (see the partial-Figure A enlarged picture). When the code is in the 60-degree position, the LED under the 60-degree lens is lit, and when the code is in the 120-degree position, the LED under the 120-degree lens is lit (see the partial-Figure B enlarged picture). When the code position is in the 90-degree position, the LEDs under the 60-degree and 120-degree lenses are both lit. When the LEDs under the two lenses are both lit and the brightness is the same, a mixed midpoint angle of 90 degrees will be generated. By adjusting the brightness difference of the LEDs under the two lenses, an angle offset phenomenon will be generated, so that a variety of mixing angles can be obtained. When the brightness of the LED under the 60-degree lens is greater than the brightness of the LED under the 120-degree lens, the mixing angle is smaller than the midpoint angle. On the contrary, when the brightness of the LED under the 120-degree lens is greater than the brightness of the LED under the 60-degree lens, the mixing angle is greater than the midpoint angle (see the reference diagram of the angle mixing principle). Based on this calculation, a full-range infinite angle adjustment of 60 to 120 degrees can be obtained through brightness adjustment. By adding a brightness matching module to the interface, any light distribution ratio can be output. The column angles shown are only for ease of understanding, and the maximum range can be 0 to 360 degrees. The shape of the lens shown can also be circular, elliptical, square, strip, or special-shaped. The placement of the lens can be horizontal splicing, vertical splicing, X-staggered, axis surround, linear diffusion, etc. Under the condition of complying with the basic working logic of the present invention, angle adjustment can be achieved.

[0084] The DIP switch 4 - working power adjustment, its switch pin is connected to the control board inside the expansion socket. By turning the switch position, the output power of the lamp can be controlled (see the enlarged view of the local figure A). When the switch is at a specific power level, the expansion socket will output a corresponding dimming signal to the lamp, thereby controlling the brightness ratio of the lamp and achieving power adjustment. The power shown in the figure is only for ease of understanding. The maximum power debugging range can be any power between 0 and the maximum lamp power, and its dimming ratio is 0~100%.

[0085] The lighting lamp D1 is a round industrial lighting fixture.

[0086] The lens waterproof ring D1-01 is equivalent to the installation waterproof ring 02 of the extension socket A1, which evolves into a lens waterproof ring according to the shape of the optical lens.

[0087] The optical lens D1-02 is equivalent to the socket body 04 of the expansion socket A1. It is based on the basic structure requirements of the expansion socket and adds an optical structure to integrate the two.

[0088] The interface plug cover D1-03 is equivalent to the interface plug cover 10 of the expansion socket A1. As an independent detachable component, it can be used for plugging an independent expansion socket and can also be used for plugging an embedded interface.

[0089] The shielding plate D1-04 is equivalent to the shielding cover 07 of the expansion socket A1. As an independent detachable component, it can be used to shield the independent expansion socket and the embedded interface.

[0090] The light board module D1-05 is equivalent to the output main board 05 and the control main board 06 of the A1 extension socket. It completely transplants the circuit part of the independent socket to the light board module of the lamp, realizing an integrated light board module, reducing the trouble of wiring transmission, and further saving resource waste in the manufacturing process. It is beautiful, stable and reliable.
