[0026] Please see Figure 1-6 This utility model provides a technical solution: a narrow beam angle LED front and rear combined lens lamp, including a connecting plate 1, a sealing front and rear lens mechanism 2 and a stable heat dissipation connection mechanism 3. The sealing front and rear lens mechanism 2 is fixedly connected to the top of the connecting plate 1, and the stable heat dissipation connection mechanism 3 is threadedly connected to the bottom of the connecting plate 1. The sealing front and rear lens mechanism 2 includes a sealing connection component 21 and a front and rear lens component 22.

[0027] The following section will explain the specific setup and function of the sealing lens mechanism 2 and the stable heat dissipation connection mechanism 3.

[0028] In this embodiment: the sealing connection assembly 21 includes a sealing gasket 211, and the front and rear lens assembly 22 includes a front lens 221 and a rear lens 222.

[0029] A sealing gasket 211 is snapped onto the top of the connecting plate 1. The top of the sealing gasket 211 is threadedly connected to the lamp housing 212. The sealing gasket 211 is snapped into the gap between the connecting plate 1 and the lamp housing 212. Bolts 213 are threadedly connected to both sides of the sealing gasket 211 and the lamp housing 212. The lamp housing 212 is threadedly connected to the top of the connecting plate 1 by the bolts 213. The front lens 221 and the rear lens 222 are fixedly connected to the inside of the lamp housing 212.

[0030] The effects achieved by the above components are as follows: the sealing gasket 211 is snapped into the gap between the connecting plate 1 and the lamp housing 212, effectively filling the gap between the two and playing a good sealing role. It can prevent external dust, moisture and other impurities from entering the lamp and protect the internal components from corrosion. At the same time, the lamp housing 212 is threadedly connected to the connecting plate 1 by bolts 213, which not only achieves a stable assembly between the lamp housing 212 and the connecting plate 1 and enhances the connection strength of the overall structure, but also further compresses the sealing gasket 211 through the tightening force of the bolts 213, improving the sealing effect and ensuring that the sealing gasket 211 can play a long-lasting and reliable sealing role, ensuring the cleanliness and dryness of the internal environment of the lamp and extending the service life of the lamp.

[0031] Specifically, the front and rear lens assemblies 22 are snapped into the interior of the lamp housing 212. The front and rear lens assemblies 22 include a double-layer positioning plate 223 fixedly connected to the inner wall of the lamp housing 212. An adhesive layer 224 is fixedly connected to the top of the positioning plate 223. The front lens 221 and the rear lens 222 are fixedly connected to the top of the positioning plate 223 through the adhesive layer 224.

[0032] The effects achieved by the above components are as follows: the positioning plate 223 enables double-layer positioning and installation of the front lens 221 and the rear lens 222, improving the stability and accuracy of lens installation; the adhesive layer 224 further ensures that the lens is firmly connected to the positioning plate 223, preventing lens displacement due to vibration and other factors during use, ensuring the stability of the light refraction path, and thus maintaining the stability of the optical performance of the lamp.

[0033] Specifically, a groove 23 is provided on the top of the lamp housing 212, and the inside of the groove 23 is fixedly connected to the glass panel 24.

[0034] The effect achieved by the above components is as follows: the groove 23 provides installation space for the glass panel 24, and the glass panel 24 covers the top of the lamp housing 212, which can protect the internal front and rear lens components 22 and other structures, blocking dust, moisture and other impurities from entering, while ensuring that light can pass through smoothly. At the same time, the transparency of the glass panel 24 does not affect the lighting effect of the lamp.

[0035] Specifically, the sealing front and rear lens mechanism 2 includes a lamp holder 25 fixedly connected to the top of the connecting plate 1. Multiple LED beads 26 are fixedly connected to the top of the lamp holder 25 at intervals. A sealing layer 27 is fixedly connected to the outer surface of the LED beads 26. The LED beads 26 are sealed to the top of the lamp holder 25 through the sealing layer 27.

[0036] The effects achieved by the above components are as follows: the lamp holder 25 provides an installation base for the LED beads 26; the multiple LED beads 26 are spaced apart to achieve uniform lighting; the sealing layer 27 can effectively isolate the LED beads 26 from the external environment, prevent moisture, dust and other substances from damaging the LED beads 26, extend their service life, and at the same time ensure the stability of the LED beads 26 in operation.

[0037] Specifically, the stable heat dissipation connection mechanism 3 includes a heat sink 31 fixedly connected to the inner bottom wall of the connecting plate 1, the top of the heat sink 31 being threadedly connected to the bottom of the lamp holder 25, and a heat sink 32 being fixedly connected to the bottom of the heat sink 31.

[0038] The effect achieved by the above components is as follows: the heat sink 31 is connected to the lamp holder 25, which can quickly absorb the heat generated by the LED lamp beads when they are working, and then dissipate the heat into the air through the heat sink 32 at the bottom, increasing the heat dissipation area, improving the heat dissipation efficiency, and preventing the lamp from being affected by excessive temperature, thus reducing its performance and lifespan.

[0039] Specifically, the heat sink 31 is threaded to the two sides with limiting members 33, and the heat sink 31 is threaded to the bottom of the lamp holder 25 through the limiting members 33. The stable heat dissipation connection mechanism 3 includes a ventilation and dustproof mesh plate 34 threaded to the center of the bottom of the connecting plate 1.

[0040] The effects achieved by the above components are as follows: the limiting component 33 further strengthens the connection between the heat sink 31 and the lamp holder 25, preventing them from loosening during use and ensuring the stability of the heat dissipation path; the ventilation and dustproof mesh plate 34 allows air circulation and helps the heat sink 31 dissipate heat, while blocking external dust from entering the interior of the connecting plate 1, avoiding dust accumulation that affects the heat dissipation effect and the normal operation of the components.

[0041] Specifically, the stable heat dissipation connection mechanism 3 includes a shock-absorbing damper 35 threaded to the four corners of the bottom of the connecting plate 1. A shock-absorbing telescopic spring 36 is sleeved on the outer surface of the shock-absorbing damper 35. A connecting protective frame 37 is fixedly connected to the bottom of the shock-absorbing damper 35. A building connector 38 is threadedly connected to the bottom of the connecting protective frame 37.

[0042] The effects achieved by the above components are as follows: the shock absorber 35 and the shock absorber extension spring 36 work together to effectively absorb and buffer the vibration and impact of the lamp during installation and use, reduce the impact on internal components, and play a protective role; the connection between the protective frame 37 and the building connector 38 makes it easy to install the lamp stably on the building structure and ensure the overall stability of the lamp installation.

[0043] Working principle: The lamp is fixed to the building structure through the building connector 38. The shock absorber 35 and the shock absorber extension spring 36 play a shock absorption and buffering role during installation and use, protecting the overall structure.

[0044] The LED beads are installed on the lamp holder 25. The heat generated during operation is conducted to the heat sink 32 through the heat sink 31. The ventilation and dustproof mesh plate 34 ensures air circulation to promote heat dissipation. The front lens 221 and the rear lens 222 are fixed inside the lamp housing 212 by the positioning plate 223 and the adhesive layer 224 to refract the light emitted by the LED beads. The refracted light passes through the glass panel 24 to achieve illumination.

[0045] The sealing gasket 211 seals the connection between the connecting plate 1 and the lamp housing 212, the sealing layer 27 seals the LED beads, and the glass panel 24 covers the top of the lamp housing 212. The multiple sealing structures prevent impurities from entering the interior and affecting the operation of the components. The whole structure works together to achieve stable, efficient and durable lighting functions.
