Description

Technical Field

[0001] This utility model belongs to the field of infrared radiation detection technology, specifically an array-type infrared radiator. Background Technology

[0002] Infrared radiation detection technology serves as a key technological support for modern security monitoring, industrial non-destructive testing, and environmental monitoring. The performance of its core component, the infrared radiator, directly determines the accuracy and efficiency of the detection system. With the increasing demand for large-area, high-precision detection across various industries, traditional single infrared radiation sources are no longer sufficient to meet the uniform coverage requirements in large-scale scenarios. Array-type infrared radiators are gradually becoming the mainstream development direction. These devices must ensure uniform infrared light output while possessing long-term stable operation capabilities to adapt to the continuous operation needs in complex industrial environments and outdoor security areas. Therefore, extremely high requirements are placed on their structural stability, optical system coordination, and heat dissipation and protection design.

[0003] In practical applications, existing infrared radiators struggle to achieve uniform and stable infrared light coverage over large areas. This manifests in three main ways: First, devices with single light sources or non-standardized array layouts have limited coverage and uneven light distribution, easily leading to blind spots or localized over- or under-intensity radiation. Second, the installation and fixing structures of core components such as optical systems and infrared light sources are poorly designed, lacking stable positioning and fastening mechanisms. These components are susceptible to positional shifts due to external vibrations and temperature changes, resulting in altered optical paths and fluctuating radiation effects. Third, some devices lack optimized auxiliary structures for long-term operation, making optical components vulnerable to dust and moisture corrosion. Insufficient heat dissipation leads to performance degradation of the light source, further affecting the stability and continuity of infrared radiation, thus failing to meet the practical needs of large-area, high-precision detection.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] An array-type infrared radiator, such as Figure 1 as well as Figure 2 As shown, it includes a substrate 1 and infrared devices 4. The substrate 1 has an array of mounting cavities 3, and the infrared devices 4 are respectively disposed within the mounting cavities 3; Figure 3 As shown, the infrared device 4 includes an optical system 5, a light source support 6, and an infrared light source 7; as Figure 5 As shown, a mounting plate 10 is provided on the base 1 at the front side of the mounting cavity 3; as Figure 4 As shown, a rear mounting groove 12 is provided on the rear side of the mounting plate 10, and an outer extension 8 is provided on one side of the optical system 5. The outer extension 8 is fitted and connected in the rear mounting groove 12. The light source bracket 6 is used to press the outer extension 8 into the rear mounting groove 12, and the light source bracket 6 is screwed to the mounting plate 10. The infrared light source 7 is connected to the side of the light source bracket 6 away from the mounting plate 10, and one side of the infrared light source 7 extends into the optical system 5.

[0027] Specifically, when the infrared radiator operates, the infrared light source 7 is first powered on, and based on its own physical characteristics, it begins to generate infrared light. The infrared light source 7 can convert electrical energy and other forms of energy into infrared radiation energy, emitting infrared light outwards as the initial energy source for the entire infrared radiation output. Light rays entering the optical system 5 from the infrared light source 7 will propagate within the optical system 5. The optical system 5 is typically composed of optical elements such as lenses and mirrors, which can perform optical processing such as collimation and focusing on the light emitted from the infrared light source 7. For example, by adjusting the direction of light propagation and the degree of convergence and dispersion, the light is transmitted along a designed optical path to better achieve the subsequent radiation function, shaping the originally divergent light into a beam form that meets the application requirements.

[0028] Due to the array-style arrangement, multiple infrared devices 4 work together to achieve uniform and wide infrared light coverage over a large area. For example, in large-area security monitoring areas such as industrial parks, large warehouses, and nature reserves, by rationally arranging this array-style infrared radiators, it can be ensured that the entire monitoring area is effectively covered by infrared light, eliminating blind spots and greatly improving the detection and sensing system's ability to detect targets over large areas, thus ensuring the comprehensiveness and effectiveness of monitoring. The mounting cavity 3 on the base 1 provides a stable mounting position for the infrared devices 4, ensuring that the relative positions of each infrared device 4 in the array are accurate and fixed. The rear mounting groove 12 on the rear side of the mounting plate 10 is connected to the outer extension 8 of the optical system 5, and the outer extension 8 is pressed into the rear mounting groove 12 by the light source bracket 6. The light source bracket 6 is connected to the mounting plate 10 with screws. This connection and fixing method allows the optical system 5 and the entire infrared device 4 to be firmly mounted on the base 1. In this way, during the process of infrared light source 7 emitting light and light transmission in optical system 5, the entire device will not be affected by slight external vibrations or other factors, such as positional shifts or changes in the optical path, thus ensuring the stable and reliable operation of the infrared radiator and the continuous output of infrared radiation processed by optical system 5.

[0029] In a preferred embodiment, such as Figure 1 As shown, three infrared devices 4 are arrayed in both the horizontal and vertical directions of the substrate 1. The arrangement of three infrared devices 4 in each direction serves two purposes: firstly, it expands the infrared radiation coverage, ensuring a larger area can be effectively detected and sensed; secondly, it enhances the uniformity of infrared light distribution, enabling targets at different locations to be detected stably and clearly, thus improving the accuracy and comprehensiveness of the entire detection and sensing system.

[0030] In a preferred embodiment, such as Figure 1As shown, the sidewalls, top, bottom, and rear of the substrate 1 are provided with several ventilation holes. The ventilation holes in the sidewalls, top, bottom, and rear of the substrate 1 facilitate the dissipation of heat inside the device, preventing heat accumulation from prolonged operation from affecting the performance and service life of the infrared device 4, and ensuring stable and reliable operation of the device.

[0031] In a preferred embodiment, a cooling fan is provided on the top of the mounting cavity 3 on the substrate 1. The cooling fan on the top of the mounting cavity 3 on the substrate 1 can accelerate airflow, more efficiently dissipate heat from the inside of the device, further enhance the heat dissipation effect, ensure that the infrared device 4 operates in a suitable temperature environment, extend its service life and maintain stable performance.

[0032] In a preferred embodiment, the cooling fan is an adjustable-speed brushless DC fan. Using an adjustable-speed brushless DC fan allows for flexible adjustment of the speed according to the actual cooling needs of the device, precisely controlling the cooling intensity and providing efficient cooling under different operating conditions. It also offers advantages such as energy saving, low noise, and long lifespan, contributing to the stable operation of the device.

[0033] In a preferred embodiment, such as Figure 5 As shown, a front mounting groove 11 is provided on the front side of the mounting plate 10, and a window protection plate 2 is provided in the front mounting groove 11. The window protection plate 2 is connected to the mounting plate 10 with screws. The window protection plate 2 can protect the internal optical system 5 and other components, preventing external dust, moisture, foreign objects and other contaminants from entering and affecting their normal operation. The screw connection facilitates installation and disassembly, and makes maintenance and replacement operations convenient.

[0034] In a preferred embodiment, the window protection plate 2 is made of high-temperature resistant and highly transparent quartz glass. Using high-temperature resistant and highly transparent quartz glass to make the window protection plate 2 not only allows it to withstand the high temperatures generated during device operation, ensuring structural stability and preventing damage, but also guarantees high infrared light transmittance, not affecting the normal detection and sensing function of the infrared radiator, while also providing protection.

[0035] In a preferred embodiment, such as Figure 4 As shown, a clamping ring 9 is also provided in the rear mounting groove 12. The light source bracket 6 uses the clamping ring 9 to press the outer extension 8 into the rear mounting groove 12. The clamping ring 9 allows the light source bracket 6 to better press the outer extension 8 into the rear mounting groove 12, enhancing the stability of the connection and preventing the optical system 5 from loosening or shifting due to vibration or other factors. This ensures the structural stability of the entire infrared device 4 and, consequently, the normal operation of the infrared radiator.

[0036] In a preferred embodiment, the light source bracket 6 is made of high-strength aluminum alloy. The high-strength aluminum alloy material ensures the bracket's structural strength, firmly securing related components and maintaining the overall stability of the device, while also providing good heat dissipation to facilitate heat dissipation and ensure reliable operation of the device.
