Description

Technical Field

[0001] The utility model relates to the technical field of LED drivers, in particular to an LED driver with wired signal transmission and overload warning protection functions. Background Art

[0002] An LED driver is an electronic device that regulates the power supply and drives the LED to illuminate or the LED module to operate normally. Due to the conduction characteristics of the LED PN junction, the voltage and current fluctuation range that it can adapt to is very narrow. A slight deviation may cause the LED to fail to light up or seriously reduce the luminous efficiency, shorten the service life or even burn out the chip. The current industrial frequency power supply and common battery power supply are not suitable for directly supplying LEDs. The LED driver is an electronic component that can drive the LED to operate at the optimal voltage or current state.

[0003] Many LED drivers currently on the market lack wired signal transmission and overload warning protection functions. All input / output ports are quick-plug ports. These LED drivers only have input and output ports, but no wired signal output. This requires wiring at the output port to connect to the control board. Furthermore, most LED drivers on the market use wiring for their input ports, which is cumbersome to install and not conducive to on-site installation. Furthermore, these LED drivers lack overload warning protection, making it difficult for many users to determine whether an LED fixture is overloaded, potentially damaging the LED driver or reducing its lifespan. Furthermore, wiring sensors to the LED driver is inconvenient. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-5As shown, the utility model provides a technical solution: an LED driver with wired signal transmission and overload warning protection functions, including an upper cover 1, a light guide 2, an LED driver module 3, an LED driver integrated control output quick wiring terminal 3-1, an LED driver non-integrated control output quick wiring terminal 3-2, an overload indicator light 3-3, a sensor series wiring terminal 3-4 between multiple LED drivers, an LED driver sensor wiring terminal 3-5, a quick plug female connector 3-6, a quick plug male connector 3-7, and a bottom cover 4. The bottom of the upper cover 1 is fixed with the bottom cover 4 by screws, and the top of the bottom cover 4 is snap-fitted with the LED driver module. 3. The LED driver integrated control output quick-connect terminal 3-1 is fixedly installed on the left side of the top of the LED driver module 3. The LED driver non-integrated control output quick-connect terminal 3-2 is fixedly installed on the rear side of the top of the LED driver module 3. The overload indicator light 3-3 is fixedly installed on the top of the LED driver module 3. The sensor series connection terminal 3-4 between multiple LED drivers and the LED driver sensor connection terminal 3-5 are fixedly installed on the front side of the top of the LED driver module 3 from left to right. The quick-connect female connector 3-6 and the quick-connect male connector 3-7 are fixedly installed on the right side of the top of the LED driver module 3 from back to front.

[0023] Specifically, the LED driver module 3 is electrically connected to the LED driver integrated control output quick wiring terminal 3-1, the LED driver non-integrated control output quick wiring terminal 3-2, the overload indicator light 3-3, the sensor series wiring terminal 3-4 between multiple LED drivers, the LED driver sensor wiring terminal 3-5, the quick plug female connector 3-6, and the quick plug male connector 3-7. The LED driver sensor wiring terminal 3-5 is electrically connected to the sensor. The sensor can be a human body sensor, a hand scan sensor, a touch sensor, a door control sensor, or a magnetic control sensor. The sensor series wiring terminal 3-4 between multiple LED drivers is used to connect multiple LED drivers to each other through sensor series wiring. The quick plug male connector 3-7 is connected to an external power cord. Multiple LED drivers are connected to each other by inserting male-female docking wiring into the quick plug female connector 3-6.

[0024] Specifically, a light guide 2 is fixed to the bottom of the upper cover 1 by screws. The light guide 2 covers the outside of the overload indicator light 3 - 3 , and the light of the overload indicator light 3 - 3 is emitted through the light guide 2 .

[0025] Specifically, the LED driver integrated control output quick connection terminal 3-1 is electrically connected to an external LED lamp.

[0026] Working principle: Figure 4As shown: After the LED driver output quick-connect terminal 3-1 is connected to the LED lamp, the LED driver input is connected to the mains power by plugging in the connection line 3-7. At this time, the lamp lights up as a regular LED driver. When the LED driver sensor terminal 3-5 is connected to the sensor, the lamp connected to the LED driver 3-1 is controlled by the sensor, and the lamp connected to the LED driver 3-3 is not controlled by the sensor.

[0027] like Figure 5 As shown: After the LED driver output quick-connect terminal 3-1 of LED driver A and LED driver B is connected to the LED lamp, and the LED driver sensor terminal 3-3 is connected to the sensor, the LED driver sensor terminal 3-4 of LED driver A is connected to the LED driver sensor terminal 3-4 of LED driver B through the sensor series line. At this time, when the output quick-connect terminal 3-1 of LED driver A and LED driver B is connected to the LED lamp, its on / off state is controlled by the sensor connected to LED driver A. No matter how many LED drivers are connected in series, the on / off state of the lamp is controlled by the sensor connected to LED driver A.

[0028] Regardless of whether the LED driver is connected to a sensor, when the LED driver output quick-connect terminal 3-1 is connected to the LED lamp, and the LED driver input terminal 3-7 is connected to the mains, when the LED lamp power is lower than the power that the LED driver can withstand, the overload indicator 3-2 will not light up or will light up green; when the LED lamp power is higher than the power that the LED driver can withstand, the overload indicator 3-3 will light up red to alert the user whether the LED lamp power exceeds the power that the LED driver can withstand. By lighting the overload indicator 3-3, the user can quickly identify whether the LED driver is overloaded.

[0029] In summary, the LED driver of this utility model has wired signal transmission and overload warning protection functions, and also has quick plug-in access to all input and output ports: through the wired signal output, it is convenient and quick to connect the sensor, and the lamp connected to the LED driver is controlled by the sensor, eliminating the trouble of connecting the lamp on the sensor control board; through the overload indicator light reminder, the user can quickly and easily identify whether the LED driver exceeds the power it carries, thereby avoiding damage to the LED driver due to overload or shortening the life of the LED driver.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
