Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of projection lamp lens assemblies, and particularly relates to a lens assembly for a wall-mounted projection lamp. Background Art
[0002] Through the control of the built-in microchip, the projection lamp can be used without a controller in small-scale engineering applications, and can achieve dynamic effects such as gradual change, jump change, color flashing, random flashing, and gradual change alternation. It can also achieve effects such as chasing and scanning through DMX control; the lens is an optical element made of a transparent substance (such as glass, crystal, etc.). The lens can be used to install at the position where the projection lamp light source emits, and this can be called a lens projection lamp. The lens projection lamp is fixed and installed on the wall for outdoor or indoor use. When the projection lamp is turned on, it starts to heat up, and the air inside the lamp will expand. The air expansion will form pressure on the rubber ring, and the air will run out. Then, after the lamp is turned off, the air pressure inside will also decrease, so the outside air will press in. In addition to air coming in, water vapor will also come in, and then it will repeat like this when working again. The water inside the lamp may accumulate more and more. After using for a period of time, water vapor condensation is likely to occur in the lens assembly inside the projection lamp, forming a mist, which affects the use effect of the projection lamp. Therefore, it is necessary to design a new lens assembly for the wall-mounted projection lamp to change the above technical defects. Summary of the Utility Model

[0005] (2) Technical Solutions
[0006] To solve the above technical problems, the present utility model provides a lens assembly for a wall-mounted projection lamp. The lens assembly includes an aluminum mounting shell. A wire tube is installed through the outer surface of the aluminum mounting shell. An LED lamp is installed inside the aluminum mounting shell, and the wire of the LED lamp is installed into the interior of the wire tube. A lamp holder is installed inside the aluminum mounting shell by screws. A spotlight lens is installed inside the aluminum mounting shell. A positioning middle ring is arranged outside the spotlight lens, and a housing is arranged outside the positioning middle ring. A lens is installed inside the housing. Air holes are arranged on the outer surface of the lamp holder, and an air groove is arranged on the outer surface at the top of the spotlight lens. Two air tubes respectively penetrate and are installed on the outer surface of the aluminum mounting shell to a first drying chamber and a second drying chamber. Filter blocks are installed inside both the first drying chamber and the second drying chamber. Through holes are formed on one side surface of the first drying chamber and the second drying chamber close to each other. A sliding rod is slidably installed inside the through hole. Piston are installed at both ends of the sliding rod, and the two pistons are respectively slidably installed inside the first drying chamber and the second drying chamber.

The lamp holder is installed into the aluminum mounting shell by screws and pressed on the LED lamp for fixation. Then, the spotlight lens is placed inside the aluminum mounting shell. Next, the positioning middle ring is installed into the aluminum mounting shell by threading and presses and fixes the spotlight lens for installation. Under the action of the second positioning groove, the positioning strip and the first positioning groove, the lamp holder and the spotlight lens can be limited in position, preventing the lamp holder and the spotlight lens from shifting or tilting during installation, enabling the lamp holder and the spotlight lens to be quickly installed. Finally, the housing is sleeved outside the aluminum mounting shell and installed with screws. When there is moisture in the lens assembly inside the projection lamp, through the action of the air groove and the air holes, air can contact both above and below the spotlight lens. Hold the sliding rod and move the two pistons respectively inside the first drying chamber and the second drying chamber. When the two pistons respectively rise in the first drying chamber and the second drying chamber, the piston rising in the first drying chamber pushes the air in the first drying chamber to pass through the filter block for drying and dust removal and enter the aluminum mounting shell through the air tube, pushing the air flow inside the aluminum mounting shell. The piston rising in the second drying chamber causes a suction force to be generated in the second drying chamber, sucking the air inside the aluminum mounting shell into the second drying chamber through the air tube. The sucked air is subjected to drying and dust removal treatment through the filter block. By repeating the above steps, the air inside the aluminum mounting shell can be circulated for drying and dust removal treatment, drying and dust removing the air in contact with the spotlight lens inside the aluminum mounting shell, preventing water vapor condensation on the surface of the spotlight lens inside the aluminum mounting shell to form a mist, and ensuring the transparency, cleanliness and use effect of the spotlight lens.
[0008] Preferably, a pull rod is fixedly connected to the outer surface of the sliding rod, and anti-slip balls are installed on the outer surface of the pull rod. Through the setting of the pull rod, it is convenient to pull the sliding rod and avoid slipping when pulling the sliding rod.
[0009] Furthermore, a fin-type heat sink group is fixedly connected to the outer surface of the aluminum installation shell. Through the setting of the fin-type heat sink group, the heat dissipation effect of the aluminum installation shell is increased, and damage caused by high temperature during the use of the projection lamp is avoided.
[0010] Even further, a sealing ring is installed at one end of the positioning middle ring close to the outer shell. Through the setting of the sealing ring, when the outer shell is sleeved on the aluminum installation shell for installation, the sealing ring is in close contact with the lens, increasing the sealing and waterproof effect of the projection lamp.
