Description

Technical Field

[0001] This utility model relates to the field of glass lens technology, and in particular to an optical glass lens. Background Technology

[0002] A lens is an optical element made of a transparent material with a surface that is part of a sphere. A lens is composed of several lenses and plays an important role in fields such as astronomy, military, transportation, medicine, and art. Optical glass can be used to manufacture lenses, prisms, mirrors, and windows in optical instruments. Components made of optical glass are key elements in optical instruments and are widely used in equipment such as streetlights.

[0003] Based on the streetlight's lighting requirements, determine the lens type, specifications, and performance parameters. Consider the streetlight's power, luminous efficacy, color temperature, and other requirements, select appropriate lens materials and designs, and purchase compliant lenses from reliable suppliers. Ensure the lens's quality, performance, and safety meet relevant standards and regulations. Before installation, inspect the lens to ensure its surface is free of scratches, stains, or other damage. Check the lens's light transmittance, focusing effect, and other optical properties to ensure they meet requirements. Install the lens onto the streetlight's lamp head according to the streetlight's assembly requirements, ensuring a tight fit without looseness or gaps. Use appropriate fixing methods, such as screws or clips, to securely fix the lens to the lamp head, ensuring the lens is not damaged or deformed during installation. After installation, debug and calibrate the streetlight, adjusting the lens's angle and position according to actual conditions to achieve the best lighting effect.

[0004] However, lenses in existing equipment are often directly exposed to the outside without necessary protection. Therefore, during transportation, installation or use, lenses are easily impacted by external objects, resulting in surface damage or breakage. Furthermore, without protection, the lens surface is easily exposed to hard objects such as dust and sand, which can cause scratches. These scratches not only affect the aesthetics of the lens but may also reduce its light transmission performance and focusing effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This solves the problem of existing lenses lacking protection and being easily scratched by dust and sand, avoiding damage or breakage of the lens surface and improving the service life of the equipment.

[0007] (II) Technical Solution

[0008] In view of the above-mentioned problems with lens protection, this utility model is proposed.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an optical glass lens, including a mounting ring, a lens slidably connected to the inner wall of the mounting ring, a protective cover slidably connected to the outer wall of the lens, two mounting cylinders that are mirror-distributed and engage with the inner wall of the mounting ring fixedly connected to the bottom end of the protective cover, a push rod slidably connected to the inner wall of the mounting cylinder, two sliding grooves that are mirror-distributed opened on the inner wall of the mounting ring, a slider slidably connected to the inner wall of the sliding groove, an exhaust fan fixedly installed on the inner wall of the mounting ring, and a heat-absorbing material installed on the inner wall of the mounting ring.

[0010] In a preferred embodiment of the optical glass lens of this utility model, the inner wall of the mounting ring is provided with a mounting groove that facilitates the sliding connection of the mounting cylinder, the inner wall of the mounting groove is slidably connected to a mounting block that is fixedly connected to the bottom end of the lens, the inner wall of the push rod is provided with a moving groove, and the inner wall of the moving groove is slidably connected to a rectangular plate that is fixedly connected to the outer wall of the push rod.

[0011] In a preferred embodiment of the optical glass lens of this utility model, a plurality of uniformly distributed first springs are connected between the outer wall of the rectangular plate and the inner wall of the moving groove; a trapezoidal block is slidably connected to the outer wall of the push rod and slidably connected to the inner wall of the mounting ring; and two mirror-distributed connecting plates are fixedly connected to the outer wall of the trapezoidal block.

[0012] In a preferred embodiment of the optical glass lens of this utility model, a second spring is connected between the outer wall of the connecting plate and the inner wall of the mounting cylinder, a groove is provided on the outer wall of the push rod to facilitate the sliding of the trapezoidal block, a push block is slidably connected to the inner wall of the mounting cylinder, and the bottom end of the push block is fixedly connected to the top end of the slider.

[0013] In a preferred embodiment of the optical glass lens of this utility model, the outer wall of the mounting block is fixedly connected to a connecting block that is slidably connected to the outer wall of the cylinder and to the slider; the outer wall of the exhaust fan is fixedly connected to a mounting bracket that is fixedly connected to the inner wall of the mounting ring; and the inner wall of the mounting ring is fixedly mounted with two filter plates that are distributed in a mirror image.

[0014] As a preferred embodiment of the optical glass lens of this utility model, wherein:

[0015] The beneficial effects of this utility model are as follows: the inner wall of the mounting ring is provided with an air duct that facilitates the installation of the exhaust fan, the inner wall of the air duct is fixedly connected with a heat dissipation plate, the inner wall of the air duct is fixedly connected with a rectangular cylinder that is slidably connected to the outer wall of the heat-absorbing material, and the inner wall of the air duct is fixedly connected with an intake fan.

[0016] 1. After pressing the push rod, insert the mounting cylinder into the inner wall of the mounting groove of the mounting ring. After releasing the push rod, the push rod pushes the trapezoidal block to engage with the inner wall of the mounting ring. The operation is simple and convenient. The protective cover prevents external impacts from directly contacting and damaging the lens, extends the service life of the equipment, reduces maintenance and replacement costs caused by accidental damage, and blocks dust, moisture and other contaminants from entering the equipment, thereby keeping the equipment clean and dry and enabling the equipment to work normally in various harsh environments.

[0017] 2. By combining the intake and exhaust fans, a reasonable airflow is formed inside the mounting ring for heat dissipation. When the temperature is too high, the heat-absorbing material inside the mounting ring melts, improving heat dissipation efficiency. Combined with the use of a heat sink, the heat convection effect is enhanced, further improving heat dissipation performance. This prevents lens material deformation, optical performance degradation, or even direct damage to the lens, ensuring that the street light maintains a stable lighting effect in harsh environments.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an optical glass lens, including a mounting ring 1. A lens 4 is slidably connected to the inner wall of the mounting ring 1, and a protective cover 2 is slidably connected to the outer wall of the lens 4. The protective cover 2 is used to protect the lens 4. Two mounting cylinders 5, which are mirror-distributed and engage with the inner wall of the mounting ring 1, are fixedly connected to the bottom end of the protective cover 2. A push rod 10 is slidably connected to the inner wall of the mounting cylinder 5. A circular plate is provided at the top end of the push rod 10 to engage with a trapezoidal block 20. Two sliding grooves 14, which are mirror-distributed, are opened on the inner wall of the mounting ring 1. A slider 11 is slidably connected to the inner wall of the sliding grooves 14. An exhaust fan 7 is fixedly installed on the inner wall of the mounting ring 1. The exhaust fan 7 is used to dissipate heat in the mounting grooves. A heat-absorbing material 6, which is graphene material, is installed on the inner wall of the mounting ring 1 and is wrapped in a soft material.

[0028] The inner wall of the mounting ring 1 is provided with a mounting groove that facilitates the sliding connection of the mounting cylinder 5. The inner wall of the mounting groove is slidably connected to a mounting block 3 that is fixedly connected to the bottom of the lens 4. The inner wall of the push rod 10 is provided with a moving groove. The inner wall of the moving groove is slidably connected to a rectangular plate 18 that is fixedly connected to the outer wall of the push rod 10.

[0029] Multiple evenly distributed first springs 19 are connected between the outer wall of the rectangular plate 18 and the inner wall of the moving groove. The first springs 19 are used to push the push rod 10. The outer wall of the push rod 10 is slidably connected to a trapezoidal block 20 that is slidably connected to the inner wall of the mounting ring 1. The trapezoidal block 20 is used to engage the mounting ring 1. The outer wall of the trapezoidal block 20 is fixedly connected to two mirror-distributed connecting plates 21.

[0030] A second spring 22 is connected between the outer wall of the connecting plate 21 and the inner wall of the mounting cylinder 5. The second spring 22 is used to push the trapezoidal block 20. The outer wall of the push rod 10 is provided with a slot to facilitate the sliding of the trapezoidal block 20. The slot is used to engage the trapezoidal block 20. A push block 13 is slidably connected to the inner wall of the mounting cylinder 5. The bottom end of the push block 13 is fixedly connected to the top end of the slider 11.

[0031] During use, when installing the protective cover 2, after squeezing the push rod 10, the mounting cylinder 5 is inserted into the mounting slot. The mounting cylinder 5 moves along the push block 13. After releasing the push rod 10, the first spring 19 is released. The first spring 19 drives the push rod 10 to reset through the rectangular plate 18. At the same time, the trapezoidal block 20, which is stuck on the inner wall of the slot, is subjected to force. Since the force-bearing surface of the trapezoidal block 20 is inclined, the trapezoidal block 20 squeezes the second spring 22 through the connecting plate 21. The trapezoidal block 20 is forced to engage with the inner wall of the mounting ring 1. When the protective cover 2 needs to be replaced, squeezing the push rod 10 squeezes the first spring 19 through the rectangular plate 18. The first spring 19 is forced to move the slot through the trapezoidal block 20. The second spring 22 is released and pushes the trapezoidal block 20 away from the inner wall of the mounting ring 1 through the connecting plate 21. The trapezoidal block 20 is forced to enter the inner wall of the slot, moving the protective cover 2 along the push block 13 away from the outer wall of the mounting ring 1.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the outer wall of the mounting block 3 is fixedly connected to a connecting block 9 that is slidably connected to the outer wall of the cylinder 12 and to the slider 11. The outer wall of the connecting block 9 is provided with a through hole to facilitate the sliding of the slider 11. The outer wall of the exhaust fan 7 is fixedly connected to a mounting bracket that is fixedly connected to the inner wall of the mounting ring 1. The inner wall of the mounting ring 1 is fixedly installed with two filter plates 8 that are distributed in a mirror image. The filter plates 8 are used to block dust from entering the mounting groove.

[0034] The inner wall of the mounting ring 1 is provided with an air duct to facilitate the installation of the exhaust fan 7. A heat sink 16 is fixedly connected to the inner wall of the air duct. The heat sink 16 transfers heat from the heat source to the heat sink 16 through heat conduction, and then the heat is dissipated by the exhaust fan 7. A rectangular cylinder 17 is fixedly connected to the inner wall of the air duct and is slidably connected to the outer wall of the heat-absorbing material 6. The outer wall of the rectangular cylinder 17 is provided with multiple through holes to facilitate heat conduction. An intake fan 15 is fixedly connected to the inner wall of the air duct. The intake fan 15 is used to cooperate with the exhaust fan 7 to form a good airflow.

[0035] During use, the micro motor inside the mounting ring 1 provides power, and the intake fan 15 draws air from outside the mounting ring 1 through the filter plate 8 into the air duct. When the LED light source is working, electrons and holes undergo radiative recombination near the PN junction, producing electroluminescence. Not all input electrical energy can be converted into light energy; most of the energy is converted into heat energy in the form of non-radiative recombination. The heat is conducted to the surface of the heat sink 16, while the exhaust fan 7 expels the heat from the outer wall of the heat sink 16 to the outer wall of the mounting ring 1. When the heat inside the mounting ring 1 is too high, the heat-absorbing material 6 absorbs the heat and liquefies, improving the internal heat dissipation effect. When the heat in the mounting groove decreases, the heat-absorbing material 6 solidifies again, thus completing the operation.

[0036] The remaining structure is the same as that in Example 1.
