Description

Technical Field

[0001] The present invention belongs to the technical field of lamps, and in particular relates to an outdoor projection wall lamp. Background Art

[0002] The projection wall lamp mainly consists of components such as a light source, a reflector, a lens, a pattern wheel, etc. The light source generates light, which is focused and shaped by the lens to make the light into parallel light or a light beam with a specific angle. When the light passes through the pattern wheel, the patterns or characters on the pattern wheel will block or transmit the light, thereby forming corresponding patterns, characters or images on the projection surface. For example, a pattern projection lamp proposed in Patent Publication No. CN108286676A.

[0003] After the projection wall lamp works for a long time, the projection wall lamp may have problems with the heat dissipation system due to reasons such as the blockage of the air inlet, resulting in abnormal temperature inside the projection wall lamp.

When the temperature inside the projection wall lamp is abnormally high for a long time, the pattern wheel made of this material will be deformed due to the abnormal temperature. And the user cannot repair the deformed pattern wheel in time. The deformed pattern wheel will cause changes in the shape, size and proportion of the pattern, and the projected pattern will no longer be the original designed appearance, and may be distorted, stretched, deformed, etc., seriously affecting the visual effect.

When the pattern wheel 37 inside the outdoor projection wall lamp is slightly deformed due to excessive temperature inside the lamp, this situation can be detected in time, and the slightly deformed pattern wheel 37 can be repaired, thus ensuring the projection effect of the projection wall lamp and eliminating the need for operators to disassemble the projection wall lamp for repair, improving the convenience of the operators' work; The insect repellent component 24 is arranged on the lower side wall of the lamp barrel 1 and is located on the right side of the heat dissipation frame 8 and is used to drive away flying insects near the lamp barrel 1.

[0022] The trimming plate assembly 16 includes a disc 161. The disc 161 is of a hollow structure. The same first telescopic tube 162 is fixedly connected between two discs 161. A heating box 17 is fixedly connected to the right side wall of the installation cylinder 101. An air pump 18 is fixedly connected to the upper side wall of the heating box 17.

A plurality of air outlet holes 23 are formed in the left and right side walls of the air outlet groove 22, and can heat and trim the deformed pattern wheel 37.

[0023] A regulating plate 30 is fixedly connected to the lower side wall of the installation cylinder 101. An adjusting frame 31 is arranged outside the regulating plate 30. Two rotating shafts 32 are rotatably connected to the inner wall of the adjusting frame 31. The opposite ends of the two rotating shafts 32 are fixedly connected to the regulating plate 30.

[0024] A laser generator 35 is fixedly connected to the side wall of the self-checking ring 141. A laser receiver 36 is fixedly connected to the right inner wall of the installation cylinder 101. The laser receiver 36 is electrically connected to the PLC controller 7, and can move the deformed pattern wheel 37 to a specified repair position.

[0025] The operating principle of the present invention is described as follows: When the pattern wheel 37 inside the outdoor projection wall lamp is deformed due to heat, the deformed pattern wheel 37 will pull or squeeze the surrounding annular thin-film pressure distribution sensor 15. When the annular thin-film pressure distribution sensor 15 detects a change in the pattern wheel 37, it will send an electrical signal to the PLC controller 7. After receiving this electrical signal, the PLC controller 7 will control the LED lamp beads 3 inside the projection wall lamp to stop emitting light, and control the corresponding laser generator 35 to work. Then, the PLC controller 7 controls the linear screw module 102 to work. The linear screw module 102 drives the three self-checking rings 141 to move downward together through the lifting seat 11, and the self-checking rings 141 also drive the laser generator 35 to move downward together. When the working laser generator 35 moves downward to the same horizontal plane as the laser receiver 36, the laser signal emitted by the laser generator 35 will be received by the laser receiver 36. After receiving this laser signal, the laser receiver 36 will control the linear screw module 102 to stop working through the PLC controller 7, so that the deformed pattern wheel 37 stays between the two discs 161. Then, the PLC controller 7 controls the air pump 18 and the heating wire 19 to work simultaneously. The air pump 18 conveys the gas heated by the heating wire 19 outside through the second telescopic tube 20 into the right disc 161 and discharges it through the air outlet holes 23, so as to heat the right side of the deformed pattern wheel 37. At the same time, part of the hot air will be conveyed to the left disc 161 through the first telescopic tube 162 and discharged through the air outlet holes 23 on the surface of the left disc 161, thereby heating the left side of the deformed pattern wheel 37. The heated gas will be discharged through the exhaust pipe 21 (a retaining net is provided in the exhaust pipe 21 to prevent impurities from entering the mounting cylinder 101). And during the heating process, the PLC controller 7 will also control the micro electric push rods 13 on the left and right sides to work. The micro electric push rods 13 on both sides will drive the discs 161 on the left and right sides to move towards the pattern wheel 37 and apply a constant extrusion force of 5N to the pattern wheel 37. Under the action of heating and extrusion, the deformed area of the pattern wheel 37 will return to its initial state. After 30 seconds of extrusion and heating work, the slightly deformed pattern wheel 37 will be restored. The PLC controller 7 will control the heating wire 19 to stop working, and the air pump 18 will blow the cooler air flow towards the pattern wheel 37 to cool and harden the pattern wheel 37, thus completing the repair of the heat-deformed pattern wheel 37; Then, the PLC controller 7 will also control the cleaning motor 281 to work. The cleaning motor 281 will drive the brush plate 29 to rotate through the rotating rod 282, and use the brush plate 29 to clean the dust attached to the surface of the dust-proof net 9, avoiding the problem of the wall lamp overheating due to the blockage of the air inlet; When the light emitted by the outdoor projection wall lamp attracts flying insects and the flying insects approach the wall lamp, they will be detected by the infrared sensor 27 on the surface of the wall lamp. After the infrared sensor 27 detects the presence of flying insects around, it will control the operation of the delivery pump 242 through the PLC controller 7. Moreover, when the infrared sensor 27 detects a relatively large number of flying insects around, the longer the time for which the delivery pump 242 is controlled to operate through the PLC controller 7, the delivery pump 242 will deliver the insect repellent stored inside the storage tank 241 (the insect repellent is peppermint essential oil, lemon eucalyptus oil, lavender essential oil, tea tree essential oil, etc., which is relatively safe for the human body) to the atomizing nozzle 25 for spraying to drive away the surrounding flying insects. And part of the insect repellent will be sprinkled on the surface of the heat dissipation rack 8, and the heat dissipated by the heat dissipation rack 8 can be used to spread the insect repellent to a farther range.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
