Description

Technical Field

[0001] The invention relates to the field of sensors, in particular to a device for studying the spatial distribution of infrared LED thermal radiation intensity. Background Art

[0002] Existing infrared meters are used to measure infrared light intensity, but cannot solve the infrared distribution situation.

[0003] There are also visible light devices, but the measurement cost is expensive, such as visible spectrophotometers, which are expensive to manufacture, and devices for measuring ultraviolet and infrared are even rarer, so the cost is too high. There are also distributed photometers, which can measure the light intensity distribution curve and light intensity data of lamps, but they cannot measure the spatial distribution of light intensity radiation. Moreover, they are expensive to manufacture, have too complex a structure, and require a special system to assist in processing data. Moreover, the detector as the light source is not easy to replace, and the supporting system software needs to be replaced, which has a high cost, and the device is complex and the operation is more complicated.

[0004] In addition, there are infrared thermal radiation imagers, but they can only perform imaging analysis on one side of an object, and cannot achieve imaging in different directions in space.

[0005] For example, in the field of welding wire processing, when using thermal radiation processing, the distribution law of thermal radiation is not taken into consideration when solving the heat dissipation problem caused by thermal radiation. Therefore, reasonable angles or distances are not used for thermal processing, resulting in energy loss, reduced efficiency, device loss, etc. Summary of the invention

[0006] The present application is made based on the fact that the above-mentioned existing technology cannot realize low-cost measurement of the spatial distribution of infrared LED thermal radiators, which can overcome multiple shortcomings of the above-mentioned background technology and realize more functions.

[0007] The present invention provides a device for measuring the spatial distribution of infrared LED thermal radiation bodies, and also provides a method for using the device for measuring the spatial distribution of infrared LED thermal radiation intensity bodies. The infrared LED thermal radiation distribution is measured from two aspects: distance and angle. The entire device is modular and has strong compatibility. The angle surface of the detector and the surface where the detection light source is located can realize double rotation to achieve the effect of measuring the spatial distribution of the body, and the detection distance can also be changed freely. Finally, the computer software is used to process the data to summarize the spatial distribution of the infrared LED thermal radiation intensity body.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a device for measuring the spatial distribution of infrared LED thermal radiation intensity, which is divided into an angle measuring component, a distance measuring component, a thermal radiation intensity measuring component and an infrared light source component.

[0009] Furthermore, the angle measuring component is composed of two length measuring components spliced ​​together at one end, and an electronic angle reading component is further installed.

[0010] The above-mentioned distance measuring component is a pulley track installed on the basis of the above-mentioned length measuring component. Furthermore, there is a pulley trolley above the track for holding the thermal radiation intensity measuring component. Furthermore, the trolley can move freely along the track and can also read specific distance data through the length measuring component.

[0011] Furthermore, the above-mentioned thermal radiation intensity measuring component is a thermal radiation intensity measuring instrument.

[0012] Furthermore, the infrared light source component is an ordinary LED board, and the temperature of the active area is relatively high, about more than 100 degrees Celsius, which belongs to black body radiation and radiates infrared rays outward. Furthermore, a heat sink is attached to the back side with a material with good thermal conductivity to prevent the LED temperature from being too high and causing damage to electronic devices. In addition, the entire component can rotate freely, which is convenient for measuring the distribution of infrared LED thermal radiation in space. Furthermore, as a detection light source, this component has the advantage of being easy to replace, which is convenient for measuring the spatial distribution of different bands.

[0013] A smooth horizontal plate is placed under all the above components to ensure that the entire device is absolutely level.

[0014] The beneficial effect of the present invention is that, by using this device for measuring the spatial distribution of the infrared LED thermal radiation intensity, it is possible to find a suitable angle and distance from the perspective of spatial distribution on the basis of the existing infrared LED thermal radiation technology, thereby maximizing the efficiency of thermal radiation and greatly reducing the measurement of infrared LEDs, thereby ensuring the infrared LED thermal radiation technology.

Obviously, the described implementation is only a part of the implementation of the present invention, not all the implementations. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please refer to the attached Figure 1 Oblique view, Figure 2 Right side view, the present invention provides a technical solution: comprising: a bracket (1), an infrared light source (2), an angle measuring component (3), an infrared thermal radiation intensity measuring component (4), a fixing component (5), a pulley trolley (6), a pulley track (7), and a light shield (8);

[0021] The bracket (1) can be made by 3D resin printing, has a convex shape, and has a platform extending from the front end for accommodating the infrared light source (2).

[0022] The infrared light source (2) can be connected to a transformer to measure the distribution of thermal radiation under different light intensities by changing the power, can rotate freely to measure the spatial distribution of thermal radiation, and the entire detection light source can also be replaced with an infrared LED light source of different bands at will; in addition, a heat sink can be glued to the back of this component with a material having good thermal conductivity. The infrared light source (2) is placed in the center of the platform at the front end of the bracket (1).

[0023] The angle measuring component (3) is an angle ruler with an angle range of 0-360°. The vertex of the angle measuring component (3) coincides with the center of the infrared light source (2) and is located directly below it.

[0024] The infrared heat radiation intensity measuring component (4) is an infrared heat radiation intensity measuring instrument. The infrared heat radiation intensity measuring component (4) is placed on a platform above the pulley trolley (6).

[0025] The pulley trolley (6) can be made by 3D resin printing, and has a pulley embedded in the bottom that can perfectly fit on the pulley track (7) and can move freely on the track, and the upper part is a platform for holding the infrared thermal radiation intensity measuring component (4). The pulley track (7) uses a track that can be freely moved by the pulley trolley.

[0026] The bracket (1) and the pulley trolley (6) have the same height and are both greater than the height of the angle measuring component (3). The fixing component (5) is three rectangular strips, which can be made by 3D resin printing and can be freely pasted on the platform above the pulley trolley (6). It is used to fix the position of the infrared thermal radiation intensity measuring component (4) on the platform above the pulley trolley (6).

[0027] The light shield (8) can isolate all external light sources including natural light, thus ensuring that the detection light source is not affected during measurement.

[0028] Working principle: When using the component for measuring the distribution of infrared LED thermal radiation intensity, first place the infrared LED light source to be measured at the exact center of the platform extending from the front end of the bracket (1), place the vertex of the angle measuring component (3) exactly below the center of the infrared LED light source and turn on the angle measurement switch, then place the infrared thermal radiation intensity measuring component (4) on the platform of the pulley trolley (6) and fix its position with the rectangular resin strip of the fixing component (5) so that the detection head of the measuring component is aligned with the exact center of the LED, then clamp the pulley trolley (6) on the pulley track (7), turn on the switch of the infrared thermal radiation intensity measuring component (4), install the light shield (8), and complete the assembly of the device.

[0029] Keep the position of the LED light source unchanged, the angle measuring component (3) on the non-track side remains stationary, and the other track side rotates, the position of the trolley on the track remains unchanged, and the reading of the infrared thermal radiation intensity is recorded accordingly according to the reading of the angle change, and a set of data is completed. Next, change the position of the trolley on the track, and record the value of the infrared thermal radiation intensity changing with the angle at different distances according to the distance change, complete the recording and integration of a series of data, and finally complete the distribution of thermal radiation when the LED light source is in a plane.

[0030] Then, the center of the LED light source is kept unchanged, the LED light source is rotated, and the above operation is repeated, and finally the thermal radiation distribution of the LED light source when it is in different planes can be obtained.
