Description

Technical Field

[0001] The invention belongs to the technical field of LED wall washer lamps, and in particular relates to an energy-saving LED wall washer lamp with an external moisture-proof and dust-discharging structure. Background Art

[0002] LED wall washer is a kind of lamp widely used in architectural lighting, landscape lighting and other fields. The LED light source emits light under the action of electric current, which is focused and scattered by the optical lens to form a specific beam angle, which is irradiated on the wall of the building or other objects to produce a wall washing effect. In order to achieve the effect of moisture resistance and heat dissipation, LED wall washer usually has heat dissipation fins outside the closed lamp shell for heat dissipation. For example, a LED wall washer is proposed in patent announcement number CN104019435B.

[0003] During the use of existing LED wall washers, the LED light source and other heating elements will generate heat. This heat is first transferred to the heat dissipation fins in contact with the heating elements through heat conduction. However, the heat dissipation fins mainly rely on heat convection and heat radiation to dissipate heat. Some LED wall washers installed close to the ground have relatively poor air circulation in the environment, and their heat dissipation efficiency will be significantly reduced under high temperature conditions in summer. It is difficult to discharge a large amount of heat in time by relying solely on the heat dissipation fins on the surface of the outer shell. If a heat dissipation port is opened on the surface of the lamp shell, external dust and moisture can easily enter the interior of the LED wall washer, which can easily cause a short circuit in the internal circuit of the LED wall washer, thereby affecting the service life of its internal components.

When the LED wall washer lamp has been working for a long time and there is a lot of dust attached to the surface of the dustproof net 6, the dust on the surface of the dustproof net 6 can be automatically cleaned, and when the external humidity is high, the dustproof net 6 will also be heated to a higher temperature to dry the dust attached to the surface of the dustproof net 6, reduce the adhesion of the dust, facilitate the cleaning of the dust on the surface of the dustproof net 6, and do not require external heating equipment to heat the dustproof net 6, thereby reducing the energy consumption of the LED wall washer lamp.

[0021] The air inlet end of the air pump 12 is fixedly connected to a U-shaped tube 44 , the right end of the U-shaped tube 44 is arranged downward, and is fixedly connected to a dust cover 45 , which can prevent rainwater from entering the air inlet end of the air pump 12 .

[0022] The lower side wall of the mounting frame 8 is fixedly connected to two adjustment frames 46, a mounting seat 47 is rotatably connected inside the adjustment frame 46, and the side wall of the adjustment frame 46 is threadedly connected to a positioning bolt 48. After the LED wall washer light is installed, the placement angle of the LED wall washer light can be adjusted according to the usage requirements of the scene, thereby improving the convenience of using the LED wall washer light.

[0023] A brush plate 49 is fixedly connected to the front side wall of the rubber sealing plate 34 . The side of the brush plate 49 with bristles is arranged toward the housing 1 , so that the dust on the surface of the dustproof net 6 can be cleaned while blocking the heat dissipation port 5 .

[0024] The operating principle of the present invention is now described as follows: the LED wall washer lamp is placed at a set position, and the mounting seat 47 is fixed by bolts, and then the placement angle of the LED wall washer lamp is adjusted, and then the positioning bolts 48 on the left and right sides are rotated, and the adjustment frame 46 and the mounting seat 47 are fixed by the positioning bolts 48, so as to fix the mounting frame 8 and the housing 1, and then the placement angle of the LED wall washer lamp is adjusted; When the LED wall washer lamp is in normal working state, the elastic rod 132 will drive the heat conducting plate 131 to contact the heat conducting seat 7, and the heat generated by the heating end of the LED light source assembly 3 will be transferred to the heat conducting plate 131 and the heat dissipation fins 14 through the heat conducting seat 7, and the heat can be discharged to the outside through the heat dissipation fins 14 (the side wall of the mounting frame 8 is provided with multiple openings, which does not affect the normal discharge of heat), and the external airflow can enter the housing 1 through the heat dissipation port 5, thereby accelerating the heat discharge of the LED wall washer lamp; When the humidity sensor 10 detects that the humidity of the outside world reaches the set threshold value (the relative humidity of the air is between 60%-70%, which will pose a potential threat to electronic components), the humidity sensor 10 will transmit an electrical signal to the PLC controller 11. After receiving the electrical signal, the PLC controller 11 first controls the air pump 12 and the first control valve 22 to work for a set time. The air pump 12 transports the external air into the annular tube 171 through the air supply pipe 172, and transports the gas to the elastic airbags 16 on both sides through the annular tube 171, so that the elastic airbags 16 are inflated. The lower end of the elastic airbag 16 squeezes the heat conducting plate 131 downward, and drives multiple heat sink fins 14 to move downward together through the heat conducting plate 131. When the heat sink fins 14 move to the bottom, the gas in the annular tube 171 will continue to increase, and the gas on the inner wall of the annular tube 171 will be discharged through the pressure pipe 18 and the pressure valve 19 under the action of the larger air pressure, thereby making the heat conducting plate 131 and the heat sink 131 The fins 14 are separated from the heat-conducting seat 7, and the heat-conducting seat 7 has a small surface area and weak heat dissipation performance, thereby reducing the heat dissipation efficiency of the LED wall washer lamp. The heat can only be discharged through the heat dissipation port 5 and the shell 1. The heat will be transferred to the dust-proof net 6 by heat conduction of the shell 1 and heat radiation of the air, so that the heat of the dust-proof net 6 is relatively high. The dust attached to the surface of the dust-proof net 6 due to moisture will become loose, which is convenient for subsequent cleaning. When the external air passes through the dust-proof net 6 and enters the shell 1, the contact area between the dust-proof net 6 and the air is large, and the moisture in the air can be processed to achieve the purpose of moisture resistance. When the external moisture is lower than 60% of the relative humidity of the air, the humidity sensor 10 will control the regulating valve 21 to open to the set time through the PLC controller 11, so that the gas inside the ring pipe 171 is discharged through the vent pipe 20, and the heat-conducting plate 131 and the heat-dissipating fins 14 will move upward under the elastic force of the elastic rod 132, and re-contact with the heat-conducting seat 7, thereby improving the heat dissipation performance of the shell 1. When the humidity sensor 10 detects that the relative humidity in the air exceeds 70%, the humidity sensor 10 will control the air pump 12 and the electric control valve 31 to work through the PLC controller 11. The air pump 12 transports the external gas to the air cylinder 251 on the right through the vertical pipe 30. The vertical pipe 30 is located behind the piston plate 252 and can transport the gas to the rear side of the piston plate 252. The two air cylinders 251 are connected through the ventilation pipe 27. The gas can be transported to the rear side of the left piston plate 252 through the ventilation pipe 27. The piston plate 252 will drive the cross bar 32 to move forward under the action of atmospheric pressure. The cross bar 32 drives the rubber sealing plate 34 and the brush plate 49 to move forward together through the short rod 33. The brush plate 49 can clean the dust on the surface of the dustproof net 6 during the forward movement. The piston plate 252 moves forward. During the movement, the push switch 26 will be driven to squeeze the front inner wall of the air cylinder 251, and the push switch 26 will control the air pump 12 to stop working through the PLC controller 11, so that the piston plate 252 stops moving. At this time, the rubber sealing plates 34 on both sides will completely block the heat dissipation port 5 to prevent external moisture from entering the shell 1. Since the external temperature is low due to the high humidity, the heat dissipation fins 14 can achieve good cooling ability. When the humidity sensor 10 detects that the relative humidity of the external air is less than 60%, the humidity sensor 10 will control the solenoid valve 29 to open, so that the gas in the air cylinder 251 is discharged through the vent pipe 28. Under the action of the spring tension, the piston plate 252 will drive the rubber sealing plate 34 to move backward to the initial position, open the heat dissipation port 5, and continue to achieve the purpose of heat dissipation. When the temperature sensor 9 detects that the outdoor temperature is higher than 35 degrees Celsius, it indicates that the outdoor temperature is high. It is difficult to reduce the temperature by relying solely on the heat dissipation capacity of the LED wall washer lamp itself. The temperature sensor 9 will control the air pump 12 and the second control valve 24 to continue to work through the PLC controller 11 (at this time, the air pump 12 works at a higher power. When the humidity sensor 10 controls the air pump 12 to work through the PLC controller 11, the air pump 12 works at a lower power). The air pump 12 delivers outdoor air to the housing 1 through the air delivery pipe 172 and the air blowing pipe 23, so that the heat under the lamp panel 2 is quickly discharged through the heat dissipation port 5. In normal conditions, the air pump 12 will not work, thereby saving energy consumption. When the temperature sensor 9 controls the air pump 12 through the PLC controller 11 to transport external air to the bottom of the lamp board 2 with a large power, when the outside of the dustproof net 6 is covered with a lot of dust, the permeability of the dustproof net 6 will become poor, and the discharge speed of the gas through the heat dissipation port 5 will decrease, while the working efficiency of the air pump 12 remains unchanged at this time, thereby increasing the air pressure in the space below the lamp board 2 (the lamp board 2 divides the interior of the shell 1 into two spaces, and the two spaces are isolated from each other), and the detection tube 351 is connected to the space below the lamp board 2 through the short tube 36. When the air pressure in the space below the lamp board 2 increases, a part of the gas will enter the bottom of the piston seat 352 through the short tube 36 under the action of atmospheric pressure, thereby increasing the air pressure in the space below the piston seat 352, and the piston seat 352 will It will overcome the elastic force of the upper spring to drive the trigger block 38 and the trigger plate 39 to contact. The trigger block 38 is electrically connected to the external power supply, and the trigger plate 39 is electrically connected to the PLC controller 11. When the trigger block 38 and the trigger plate 39 are in contact, an electrical signal will be transmitted to the PLC controller 11. After receiving the electrical signal, the PLC controller 11 will indicate that the surface of the dustproof net 6 is covered with a lot of dust. The PLC controller 11 will control the micro motor 40 to work. The micro motor 40 drives the ball 43 to rotate through the turntable 41 and the connecting rope 42. The ball 43 will continuously knock on the dustproof net 6 during the rotation process, so that the dust on the surface of the dustproof net 6 will be shaken off. The shaken off dust will be discharged from the dustproof net 6 under the action of the airflow, thereby ensuring the ventilation efficiency of the dustproof net 6.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
