Its main components include LED lamp beads (light source), PCB boards (circuit boards), drivers and protective devices (housings), etc. The design of this module enables it to provide efficient and energy-saving lighting solutions in different application scenarios. In addition, LED modules have differences in structure and electronics, and can be used to form lighting and decorative products through packaging, waterproofing and control systems, etc., and are one of the most widely used LED products. Existing lighting modules have the following main problems: (1) There is no internal cooling, which causes the circuit board to burn out, and (2) The focus cover is not cleaned regularly, resulting in poor light transmittance. Summary of the invention

[0003] The object of the present invention is to provide an LED lighting module with adjustable lighting angle to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an LED lighting module with adjustable lighting angle, comprising a shell, a condenser is installed in the shell, a cleaning plate is installed on one side of the condenser, a photoresistor plate and a brush plate are installed on the cleaning plate, a moving plate is installed on one side of the cleaning plate, a detection plate is installed on the other side of the condenser, a light source is installed on one side of the detection plate, a circuit board is installed on one side of the light source, a refrigeration plate is installed on one side of the circuit board, a coil is installed on the outer side of the detection plate and the refrigeration plate, and a sliding plate is installed on one side of the coil;

[0005] The brush plate cleans the condenser, the photoresistor plate detects the light intensity of the condenser, the detection plate detects the temperature of the circuit board and the light source, the refrigeration plate cools the circuit board and the light source, and the detection plate, refrigeration plate and coil cooperate to realize position detection.

[0006] The cleaning plate is composed of an inner sleeve and an outer sleeve, the inner sleeve and the outer sleeve are connected in a sliding and sealing manner by a spring and a sealing ring, the outer sleeve limits and supports the inner sleeve, the photoresistor plates are provided in multiple groups, the multiple groups of photoresistor plates are installed on the lower side of the inner sleeve and the outer sleeve, the brush plate is installed on the inner sleeve and the outer sleeve between two adjacent groups of photoresistor plates, the multiple groups of photoresistor plates are higher than the brush plate, a movable plate is rotatably installed on one side of the outer sleeve through a bearing, and a first spring is connected between the outer sleeve and the movable plate;

[0007] The outer shell at the lower side of the movable plate is provided with an annular groove, an annular shaft is arranged in the annular groove, the lower side of the movable plate and the annular shaft are slidably connected, an annular spring is connected between the movable plate and the annular shaft, and the annular spring is sleeved on the annular shaft; the annular groove and the annular shaft are adapted, the movable plate slides and limits in the annular groove, and the movable plate and the annular groove form a sliding sealing connection;

[0008] The multiple groups of photoresistor plates are composed of photosensitive materials and transparent covers. The photosensitive materials are electrically connected to the control system. The transparent covers cover the photoresistor materials. The photosensitive materials and the transparent covers are installed on the inner sleeve and the outer sleeve. The first spring is electrically connected to the control system. The transparent cover prevents external dust or impurities from contacting the photoresistor materials, and has the function of protecting the photoresistor materials.

[0009] After the lighting module works for the set time, dust is easily attached to the surface of the condenser, and regular cleaning is required. After the control system cuts off the power to the metal blocks on both sides, it connects the two ends of the coil to AC power. The two ends of the coil alternately generate positive magnetic fields and reverse magnetic fields. The positive magnetic field attracts the magnetic material on the sliding plate. The sliding plate moves downward under the attraction and stretches the spring. The volume of the chamber formed between the upper side of the sliding plate, the inner wall of the outer shell and the outer side of the inner shell becomes larger, and the external air enters the chamber through the air inlet and the one-way valve (the one-way valve in the air inlet). After that, the reverse magnetic field repels the magnetic material on the sliding plate. The sliding plate moves upward under the repulsive force and the spring tension. After the air pressure in the chamber increases, it is transported to the outer sleeve or the first chamber through the air outlet, the one-way valve (the one-way valve in the air outlet) and the pipeline. The air is extracted and pressurized by the positive magnetic field and the reverse magnetic field generated by the coil, and the structure is more compact. The control system can adjust the current size and frequency of the coil to adjust the pressurization frequency.

[0010] When pressurized air is delivered to the outer sleeve through the pipeline, the flow meter in the outer sleeve connecting pipeline feeds back data to the control system, and the control system opens the switch valve in the outer sleeve connecting pipeline. After the pressurized air enters the outer sleeve, it pushes the inner sleeve to move outward, and the inner sleeve stretches the spring (the spring connected between the inner sleeve and the outer sleeve) at the same time. The brush plate and the photoresistor plate on the lower side of the inner sleeve follow and move outward, and the cleaning plate becomes longer as a whole. After the pressure sensor in the outer sleeve connecting pipeline detects that the outer sleeve and the inner sleeve are pressurized to the set pressure, it feeds back data to the control system, and the control system closes the switch valve in the outer sleeve connecting pipeline to ensure that the air in the outer sleeve and the inner sleeve will not leak. The set pressure is set in advance by the staff through the control system.

[0011] After the outer sleeve and the inner sleeve are pressurized to the set pressure, the control system controls the first spring to be energized. The first spring gradually contracts under the influence of the magnetic field generated by each turn to attract each other. The first spring pulls the outer sleeve to rotate a certain angle, and the outer sleeve drives the inner sleeve to rotate a certain angle synchronously, so that the photoresistor plate and the brush plate on the lower side of the inner sleeve and the outer sleeve rotate from the outside of the condenser to the top of the condenser.

[0012] When the photoresistor plate and the brush plate move to the top of the condenser, the photoresistor plate is affected by the light emitted by the condenser, causing the resistance value to change, and the current in the photosensitive material connection loop changes. The control system detects the loop current, obtains the light intensity on the lower side of the photoresistor plate by calculation, and feeds the data back to the control system. The control system controls the switch valve in the connecting pipe on one side of the annular groove to open, and the pressurized air enters the first chamber through the pipe. After entering the first chamber, the pressurized air pushes the moving plate to slide on the annular groove and the annular shaft, and the second chamber is exhausted to the outside of the shell through the pipe. The moving plate compresses the annular spring at the same time, and the moving plate is pressurized. The influence of the annular axis limits the motion trajectory to a circular ring. The moving plate drives the cleaning plate, the photoresistor plate and the brush plate to move along the circular motion trajectory from one end of the annular groove to the other end, so that the multiple groups of photoresistor plates on the lower sides of the inner sleeve and the outer sleeve successively detect the light intensity emitted from multiple positions of the condenser along the circular motion trajectory, and compare it with the set light intensity. While the moving plate moves, the pull rope in the pull rope sensor is lengthened, and the pull rope sensor feeds back the displacement data to the control system in real time. The light intensity detection of the condenser is realized through the cooperation of the pull rope sensor and multiple photoresistor plates, and then the control system determines whether cleaning is needed.

[0013] An inner shell is installed in the outer shell, the coil is installed on the outer side of the inner shell, sliding grooves are provided on both sides of the inner shell, the detection plate and the refrigeration plate are both slidably connected to the inner shell, the inner shell limits the detection plate and the refrigeration plate, metal blocks are provided on one side of the detection plate and the refrigeration plate, two groups of the metal blocks pass through the sliding grooves and are in sliding contact with the coil, the detection plate and the refrigeration plate are both connected to the output shaft of the electric cylinder, and the electric cylinders on both sides are installed on the inner shell; the coil and the two groups of metal blocks are electrically connected to the control system;

[0014] When the detection board or the refrigeration board detects or cools down the light source and the circuit board, the control system connects one end of the coil and the metal block (the metal block on the detection board or the refrigeration board) to the circuit. The current enters from the metal block, flows through the effective turns of the coil, and flows out from one end of the coil to the control system, forming a detection loop. The control system detects the current in the detection loop and calculates the position data of the metal block, that is, the position data of the detection board or the refrigeration board, through the control system. The control system controls the electric cylinder to drive the moving distance of the detection board or the refrigeration board through the position data. The effective turns refer to the number of turns from the metal block to one end of the coil.

[0015] The sliding plate is installed between the outer shell and the inner shell, the sliding plate is located above the detection plate, the sliding plate is connected to the outer shell and the inner shell through a sliding seal, a spring is connected between the sliding plate and the outer shell, a magnetic material is provided on the side of the sliding plate close to the coil, and a magnetic shielding material is provided on the side of the sliding plate away from the coil.

[0016] Telescopic plates A are installed on both sides of the movable plate, and telescopic plates B are installed on both sides of the metal blocks on the detection plate and the refrigeration plate. The telescopic plates A on both sides block the annular groove to prevent the air in the annular groove from leaking out, and the telescopic plates B on both sides block the sliding groove. Both the telescopic plates A and B are telescopic structures;

[0017] The telescopic plate A connects the movable plate and the outer shell, and the telescopic plate B connects the metal blocks on the detection plate and the refrigeration plate to the inner shell respectively. The telescopic plate A stretches or contracts following the movement of the movable plate to ensure the shielding of the annular groove, and the telescopic plate B stretches and contracts following the movement of the detection plate and the refrigeration plate to ensure the sealing of the circuit board and the light source, etc.

[0018] The staff installs the outer shell by adjusting the mounting holes and bolts on the plate, presses the start button on the control panel, and the control system turns on the light source. The light emitted by the light source is converged by the condenser and then emitted through the condenser to realize the lighting function of the lighting module.

[0019] When the lighting module is working normally, the electric cylinder on the upper side drives the detection plate to move downward, so that the detection plate is close to the light source and the circuit board. The heat generated by the circuit board and the light source during long-term operation is conducted to the hot end of the detection plate, and current is generated between the hot end and the cold end and transmitted to the control system. The control system first detects the current and then calculates the temperature around the light source and the circuit board. After that, the control system rectifies and transforms the current for cooling the cooling end. When the control system detects that the current generated by the hot end and the cold end is small, the control system directly supplies power to the cooling end.

[0020] After the control system obtains the temperature data of the light source and the circuit board, it compares the measured temperature data with the set temperature data. If the detected temperature data is greater than the set temperature data, the control system drives the detection plate to move upward through the upper electric cylinder so that the hot end on the detection plate is not close to the light source and the circuit board. After that, the control system controls the lower electric cylinder to drive the cooling plate to move upward so that the cooling plate is close to the light source and the circuit board. The control system connects the two semiconductors on the cooling plate to the circuit to cool the light source and the circuit board. If the detected temperature data is less than the set temperature data, the detection board continues to generate current through the hot end and the cold end and transmits it to the control system. The set temperature data is set in advance by the staff through the control panel.

[0021] An air inlet and an air outlet are provided on the housing near the sliding plate, the air inlet is located on one side of the air outlet, the air inlet is communicated with the external atmosphere, a first chamber is formed between one side of the moving plate, the lower side of the telescopic plate A and the inner wall of the annular groove, a second chamber is formed between the other side of the moving plate, the lower side of the telescopic plate A and the inner wall of the annular groove, the air outlet is respectively connected to the outer sleeve and the inside of the first chamber through a plurality of pipes, and the second chamber is communicated with the external atmosphere through the pipe;

[0023] A plurality of hot plates are installed on the detection plate, and a plurality of cold plates are installed on the inner walls of the inner sleeve and the outer sleeve, and the plurality of hot plates and cold plates correspond to each other one by one;

[0024] The hot plate, cold plate and refrigeration plate are all provided with semiconductors of two different materials and a metal plate, one end of the semiconductors of two different materials is connected to the metal plate, the two semiconductors on the hot plate and the two semiconductors on the cold plate are connected by wires, one of which is electrically connected to the control system, and the two semiconductors on the refrigeration plate are electrically connected to the control system through wires;

[0026] The brush plates are slidably mounted on the inner sleeve and the outer sleeve by springs, and isolation membranes are connected between the inner sleeve and the outer sleeve on all sides of the multiple groups of brush plates. The isolation membranes prevent the air in the inner sleeve and the outer sleeve from leaking through the gap on one side of the brush plates, and the isolation membranes are made of flexible material.

A worker can fix and install the shell by passing a bolt through the mounting hole, and can also adjust the angle of the shell through the mounting hole, thereby achieving adjustment of the lighting angle.

[0029] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0030] 1. Clean the condenser regularly to ensure that the condenser has good light transmittance. The resistance value of the photoresistor plate changes due to the influence of the light emitted by the condenser, and the current in the photosensitive material connection loop changes. The control system detects the loop current, calculates the light intensity on the lower side of the photoresistor plate, and feeds the data back to the control system. The moving plate is affected by the annular axis and limits the movement trajectory to a circular ring. The moving plate drives the cleaning plate, the photoresistor plate and the brush plate to move along the circular motion trajectory from one end of the annular groove to the other end, so that the multiple groups of photoresistor plates on the lower side of the inner sleeve and the outer sleeve detect the light intensity of the light emitted from multiple positions of the condenser in turn along the circular motion trajectory, and compare it with the set light intensity. The light intensity detection of the condenser is realized through the cooperation of the pull rope sensor and multiple photoresistor plates, and then the control system determines whether cleaning is needed.

[0031] 2. Monitor the working temperature of the light source and circuit board in real time to ensure the safe use of the lighting module. After measuring the temperature data of the light source and circuit board, compare the measured temperature data with the set temperature data. If the detected temperature data is greater than the set temperature data, the control system drives the detection plate upward through the upper electric cylinder to make the hot end on the detection plate not close to the light source and circuit board. The control system controls the lower electric cylinder to drive the cooling plate upward to make the cooling plate close to the light source and circuit board. The control system connects the two semiconductors on the cooling plate to the circuit to cool the light source and circuit board. If the detected temperature data is less than the set temperature data, the detection board continues to generate current through the hot end and the cold end and transmits it to the control system. The control system can obtain the temperature data of the light source and circuit board and then judge the status to ensure the safe use of the lighting module.

[0032] 3. Cool down the circuit board and light source to extend its service life. The heat generated by the circuit board and light source working for a long time is transferred to the hot end of the detection board. Current is generated between the hot end and the cold end and transmitted to the control system. The control system first detects the current and then calculates the temperature around the light source and the circuit board. After that, the control system rectifies and transforms the current for cooling at the cooling end, which cools the circuit board and light source. BRIEF DESCRIPTION OF THE DRAWINGS

After that, the control system rectifies and transforms the current for cooling the cooling end.

[0055] After the control system obtains the temperature data of the light source 17 and the circuit board 16, it compares the measured temperature data with the set temperature data. If the detected temperature data is greater than the set temperature data, the control system drives the detection plate 3 to move upward through the upper electric cylinder 25, so that the hot end on the detection plate 3 is not close to the light source 17 and the circuit board 16. After that, the control system controls the lower electric cylinder 25 to drive the refrigeration plate 31 to move upward, so that the refrigeration plate 31 is close to the light source 17 and the circuit board 16. The control system connects the two semiconductors on the refrigeration plate 31 to the circuit to cool the light source 17 and the circuit board 16. If the detected temperature data is less than the set temperature data, the detection board 3 continues to generate current through the hot end and the cold end and transmits it to the control system. The set temperature data is set in advance by the staff through the control panel.

[0056] After the lighting module has been working for a set time, dust is easily attached to the surface of the condenser 12, and regular cleaning is required. After the control system cuts off the power to the metal blocks 24 on both sides, the two ends of the coil 15 are connected to the alternating current. The two ends of the coil 15 alternately generate a positive magnetic field and a reverse magnetic field. The positive magnetic field attracts the magnetic material on the sliding plate 14. The sliding plate 14 moves downward under the action of the attraction and stretches the spring. The volume of the chamber formed between the upper side of the sliding plate 14, the inner wall of the outer shell 11 and the outer side of the inner shell 111 becomes larger, and the external air passes through the inlet. The air port 19 and the one-way valve enter the chamber, and then the reverse magnetic field and the magnetic material on the sliding plate 14 repel each other. The sliding plate 14 moves upward under the action of the repulsive force and the spring tension. The air pressure in the chamber increases and is transported to the outer sleeve or the first chamber 27 through the air outlet 191, the one-way valve and the pipeline. The positive and reverse magnetic fields generated by the coil 15 are used to extract and pressurize the air, and the structure is more compact. The control system can adjust the current and frequency of the coil 15 to adjust the frequency of pressurization.

[0057] When pressurized air is delivered to the outer sleeve through the pipeline, the flow meter in the outer sleeve connecting pipeline feeds back data to the control system, and the control system opens the switch valve in the outer sleeve connecting pipeline. After the pressurized air enters the outer sleeve, it pushes the inner sleeve to move outward. At the same time, the inner sleeve stretches the spring, and the brush plate 132 and the photoresistor plate 131 on the lower side of the inner sleeve follow and move outward. The cleaning plate 13 becomes longer as a whole. After the pressure sensor in the outer sleeve connecting pipeline detects that the inside of the outer sleeve is pressurized to the set pressure, it feeds back data to the control system, and the control system closes the switch valve in the outer sleeve connecting pipeline to ensure that the air in the outer sleeve and the inner sleeve will not leak. The set pressure is set in advance by the staff through the control system.

[0058] After the inner part of the outer sleeve and the inner sleeve is pressurized to the set pressure, the control system controls the first spring 23 to be energized, and each turn of the first spring 23 generates a mutually attractive magnetic field. Each turn of the first spring 23 gradually contracts under the action of the mutually attractive magnetic field, and the first spring 23 pulls the outer sleeve to rotate a certain angle, and the outer sleeve drives the inner sleeve to rotate a certain angle synchronously, so that the photoresistor plate 131 and the brush plate 132 on the lower side of the inner sleeve and the outer sleeve are rotated from the outside of the condenser 12 to the top of the condenser 12.

[0059] When the photoresistor plate 131 and the brush plate 132 move to the top of the condenser 12, the photoresistor plate 131 is affected by the light emitted by the condenser 12, causing the resistance value to change, and the current in the photosensitive material connection loop changes. The control system detects the loop current, and obtains the light intensity on the lower side of the photoresistor plate 131 by calculation, and feeds the data back to the control system. The control system controls the switch valve in the connecting pipe on one side of the annular groove 18 to open, and the pressurized air enters the first chamber 27 through the pipe. After entering the first chamber 27, the pressurized air pushes the moving plate 22 to slide on the annular groove 18 and the annular shaft 21, and the second chamber 28 is exhausted to the outside of the housing 11 through the pipe. The moving plate 22 compresses the annular spring 211 at the same time, and the moving plate 22 moves to the outer surface of the housing 11. The movable plate 22 is affected by the annular shaft 21 and limits its motion trajectory to a circular ring. The movable plate 22 drives the cleaning plate 13, the photoresistor plate 131 and the brush plate 132 to move along the circular motion trajectory from one end of the annular groove 18 to the other end, so that the multiple groups of photoresistor plates 131 on the lower side of the inner sleeve and the outer sleeve detect the light intensity of the light emitted from multiple positions of the condenser 12 in turn along the circular motion trajectory, and compare it with the set light intensity. When the movable plate 22 moves, the pull rope in the pull rope sensor is lengthened, and the pull rope sensor feeds back the displacement data to the control system in real time. The light intensity detection of the condenser 12 is realized through the cooperation of the pull rope sensor and multiple photoresistor plates 131, and then the control system determines whether cleaning is needed.

[0060] When multiple photoresistor plates 131 detect the condenser 12, when the light intensity detected by the photoresistor plate 131 is lower than the set light intensity, the control system determines that there is dust on the condenser 12 at that position and needs to be cleaned, and the pull-rope sensor (the pull-rope of the pull-rope sensor is positioned through the outer shell 11) feeds back the position data of the movable plate 22 and the photoresistor plate 131 to the control system. When the light intensity detected by the photoresistor plate 131 is the same as the set light intensity, the control system determines that the condenser 12 at that position does not need to be cleaned, and the pull-rope sensor feeds back the data to the control system, and the control system then obtains the position of the condenser 12 that needs to be cleaned and the position that does not need to be cleaned.

[0061] After the control system obtains the data of the position of the condenser 12 that needs to be cleaned and the position that does not need to be cleaned, the control system opens the pressure relief valve of the first chamber 27, so that the pressure of the first chamber 27 is reduced after the air is discharged, and the annular spring 211 is released. The annular spring 211 pushes the movable plate 22 to move reversely to prepare for cleaning the condenser 12, that is, the forward movement of the cleaning plate 13 is to detect the light intensity of the condenser 12, and the reverse movement of the cleaning plate 13 is to clean the condenser 12.

[0062] When the moving plate 22 moves in the reverse direction, the control system opens the switch valve in the connecting pipe of the cleaning plate 13 according to the data of the pull-wire sensor, and the pressurized air further enters the outer sleeve, so that the pressure in the outer sleeve and the inner sleeve increases to exceed the set pressure. At this time, the inner sleeve cannot move outward after moving to the outermost side of the outer sleeve, and the pressurized air pushes the brush plate 132 to move downward and contact the condenser 12. The brush plate 132 compresses the spring on the lower side. The brush plate 132 moves in the reverse direction with the moving plate 22 and cleans the dusty position of the condenser 12. When the brush plate 132 moves to a position that does not need to be cleaned, the pull-wire sensor feeds back the data to the control system. The control system uses the pressure sensor in the connecting pipe of the outer sleeve and releases the pressure inside the outer sleeve and the inner sleeve to the set pressure through the pressure relief valve on the inner sleeve. The spring pushes the brush plate 132 in the reverse direction so that it does not contact the condenser 12. The switch valve in the connecting pipe of the outer sleeve, the pressure relief valve on the inner sleeve and the pressure sensor in the connecting pipe of the outer sleeve cooperate with each other to realize the control of whether the brush plate 132 cleans the condenser 12.
