[0022] Figure 1 This is a schematic diagram of the structure of this embodiment; only a portion of the columns are shown in the diagram.

[0023] Figure 2 This is a schematic diagram of the lamp elevation angle algorithm in this embodiment.

[0024] The components include: a reflector 1, a laser module 2, a vertical laser line 2a, a base 3, a scale plate 4, a column 5, and a lamp 6. Detailed Implementation

[0025] Example 1

[0026] like Figure 1 As shown, the non-contact elevation angle measurement system for a vertical approach luminaire provided in this embodiment includes a reflector 1, a laser module 2, a base 3, and a scale plate 4. The reflector 1 is fixedly installed on the outer wall of the vertical approach luminaire 6, with the mirror surface of the reflector 1 parallel to the light emission direction of the luminaire 6. The laser module 2 is positioned directly below the reflector 1, emitting a vertical laser line 2a upwards towards the reflector 1. The base 3 is placed on the ground, and its own adjustment structure maintains the laser module 2 in a horizontal working state. The scale plate 4 is horizontally arranged, and markings are set on its surface to visually identify the distance between the light spot and the vertical laser line 2a.

[0027] The vertical laser line 2a emitted from laser module 2 is reflected after hitting reflector 1, and the reflected beam is projected onto the surface of scale plate 4 to form a light spot. The elevation angle of lamp 6 satisfies the calculation formula: .in The angle between the lamp 6 and the reflector 1 relative to the horizontal direction is denoted as . This represents the height of the scale plate 4 along the vertical laser line 2a to the reflector 1. This represents the distance between the light spot on the scale plate 4 and the vertical laser line 2a.

[0028] The algorithm principle for the 6-angle elevation of the lamp is as follows: Figure 2 As shown, the known condition is: ∠COD = AO= AB= Let EO be the angle bisector of ∠AOB, EO⊥CO, AO⊥DO, and AB⊥AO. From the given conditions, we know that ∠COD + ∠DOE = ∠AOE + DOE = 90°, therefore ∠AOE = ∠COD = 90°. Furthermore, we can obtain ∠AOB = 2. Therefore, we can eventually obtain .

[0029] In this embodiment, the scale plate 4 adopts a fan-shaped structure. The corners of the fan-shaped scale plate 4 are rotatably mounted on the base 3, ensuring that regardless of its placement, the light spot can fall on the scale plate 4 by rotating it. The laser module 2 is a laser rangefinder, which is vertically mounted at the corner of the fan-shaped scale plate 4. Multiple concentric arcs are arranged on the surface of the scale plate 4 as distance markers, and the radius corresponding to each arc is the distance from that position to the vertical laser line 2a.

[0030] Base 3 is equipped with an automatically adjustable level, which can autonomously complete the leveling calibration.

[0031] The measurement system is additionally equipped with a communication module and a mobile terminal. The communication module and the laser rangefinder are electrically connected. The communication module transmits the data acquired by the laser module 2. The value is transmitted to the mobile terminal. The operator enters the value on the mobile terminal. The value is determined by the mobile terminal relying on its built-in computing program and the received data. The value calculation yields the 6-angle elevation of the lamp. .

[0032] The base of the upright approach light fixture 6's column 5 is equipped with an identification tag. Operators use a mobile phone to take a photo and obtain identification information through image recognition. The captured images simultaneously retain the identification mark of the lamp 6, facilitating subsequent data traceability.

[0033] This embodiment also provides a non-contact measurement method for the elevation angle of a vertical approach luminaire at 6 degrees. The measurement process is as follows:

[0034] S1. Complete the fixed assembly of reflector 1 on the vertical approach luminaire 6. Reflector 1 is a permanent fixed assembly. It can be installed when the luminaire 6 leaves the factory or when the elevation angle is measured for the first time. Once installed, it can be used permanently. Specifically, reflector 1 is fastened to the housing of vertical approach luminaire 6 to ensure that the light output direction of reflector 1 and luminaire 6 is parallel.

[0035] S2. Place the base 3 integrating the laser module 2 and the scale plate 4 directly below the reflector 1. The laser rangefinder emits a vertical laser line 2a upwards. At the same time, the base 3 has an automatic adjustable level to complete the horizontal adjustment. The position is calibrated with the help of the laser module 2. The plane position of the base 3 is adjusted to ensure that the vertical laser line 2a hits the preset area on the surface of the reflector 1.

[0036] S3, Laser rangefinder collects vertical height data in real time. The communication module transmits the data measured by laser module 2. The value is pushed to the mobile terminal. After being deflected by the reflector 1, the laser is projected onto the fan-shaped scale plate 4 to form a light spot. The operator uses a mobile phone to photograph the light spot area on the scale plate 4 and the identification mark at the bottom of the lamp 6 and the column 5. The mobile terminal recognizes the image information to obtain the distance. value;

[0037] S4. The mobile terminal automatically calculates the lamp's elevation angle according to the formula. And bind the elevation angle data with the corresponding vertical approach luminaire information;

[0038] S5. After completing one set of measurements, move the base 3 so that the laser illuminates other marked areas of the reflector 1. Repeat steps S2 to S4 at least twice to obtain at least three sets of elevation angles. Detected values;

[0039] S6, For multiple sets of elevation angles The arithmetic mean of the measured values ​​is used as the final result of the six elevation angle tests for this lighting fixture.

[0040] At least three areas of equal size are pre-marked on the surface of the reflector 1. When performing step S5 to change the position of the base 3 for retesting, after each adjustment, the vertical laser line 2a is controlled to be incident on different areas on the reflector 1 to eliminate measurement interference caused by local planar deviations of the reflector 1.

[0041] In this embodiment, all measurement data is linked to and stored with the identification of the luminaire 6, enabling full traceability through photographic evidence. The entire measurement process requires no contact with the light-emitting part of the luminaire 6, making it highly adaptable to different locations and simple to operate.

[0042] Example 2

[0043] The basic structure of this embodiment is consistent with that of Embodiment 1, except that: the scale plate 4 is a circular structure, and the circular scale plate 4 is horizontally placed above the base 3. Multiple concentric circles are arranged on the surface of the scale plate 4 as distance markers, and the radius of any concentric circle represents the distance from the circumference position to the vertical laser line 2a. The laser module 2 is a laser rangefinder, which is vertically fixed at the center of the circular scale plate 4.
