②	Click to rotate the Gamma axis to the 0-degree position
③	Click, and the single-character laser begins to rotate on its own.

그림 31.4

Secure a sheet of white paper at the far end of the darkroom. Use a pen to trace the path of the red laser dot, creating a circular pattern of varying sizes, as shown by the black circular path in the figure below.

그림 31.5

Click the “Stop” button on the “Angle Control” interface to stop the straight-line laser from rotating. Then, depending on the actual situation, adjust the four small Allen screws shown in the figure below to align the straight-line laser spot exactly at the center of the circular path, as indicated by the red arrow in the figure above.

그림 31.6

Then restart the straight-line laser’s rotation, redraw the trajectory, and repeat the above steps until the trajectory of the straight-line laser dot forms a point (or the trajectory radius is small enough), rather than a circle. Then click the “Stop” button on the “Angle Control” interface to stop the straight-line laser from rotating. Once debugging is complete, all four small Allen screws on the single-line laser should be fully tightened.

Note: Once the single-line laser has been properly calibrated, it must remain attached to the Goniophotomoeter until the installation and calibration are complete before being removed.

5.1.2 Crosshair Laser Ready

십자선 레이저 장치와 삼각대를 찾으세요.

그림 32

십자선 레이저와 배터리를 분리하세요. 배터리를 십자선 레이저에 넣으세요. 전원 스위치는 기기 측면에 있습니다. 스위치를 "잠금 해제" 위치로 돌려 기기를 켜세요.

Note: The cross-line laser is self-leveling. If it is not self-leveled, an audible alarm will sound. This may be due to an uneven surface or an improperly set up tripod. Please ensure that the cross-line laser remains self-leveled at all times during use.

5.1.2 Steps for Horizontal Commissioning of the Host Machine

암실 도면에 따르면, 중심 높이는 다음과 같습니다. LSG-1800A goniophotomoeter is 1375 mm. Using a tripod, adjust the height of the horizontal laser beam from the crosshair laser to 1375 mm. At this height, the horizontal laser beam should pass through the center of all light-transmitting holes in the darkroom partition.

그림 34

주의: 회전 중 장비 손상을 방지하기 위해 고니오포토미터 위 또는 회전 범위 내에 어떠한 물체도 올려놓지 마십시오.

Click the continuous rotation button in any direction, and the Gamma axis of the Goniophotomoeter will begin to rotate continuously.

그림 36

At this point, observe the horizontal laser beams emitted by the single-line and cross-line lasers from the main axis of the Goniophotomoeter.

그림 37

Then, using an appropriate wrench, raise the goniophotomoeter and level it by adjusting the height of its four support legs. The final result of the calibration: regardless of the Gamma angle of the goniophotomoeter, its straight laser beam is perfectly aligned with the horizontal laser beam, as shown in the figure below.

그림 38

You’ll need plenty of patience to complete this step. Once the adjustment is complete, make sure all four legs of the main unit are firmly on the ground. Then click the “Stop” button on the software’s angle control interface to stop the Goniophotomoeter from rotating. Next, secure the four legs of the Goniophotomoeter by tightening the screws at the top of each leg. Once the position and level of the Goniophotomoeter main unit have been properly adjusted, do not move it again, as doing so will cause the test results to be inaccurate.

Note 2: Definition of the Gamma angle for a goniophotomoeter. The direction directly facing the photometer probe is defined as 0 degrees/360 degrees. When rotated clockwise, the angle value increases from 0 degrees to 360 degrees; when rotated counterclockwise, the angle value decreases from 360 degrees to 0 degrees. Since angle notation may vary, -90 degrees and 270 degrees correspond to the same position.

5.2.2 광도 측정 프로브 장착

Rotate the light sensor’s lens hood counterclockwise and remove it.

그림 41

The standard lamp packaging box contains a small mirror.

그림 42

그림 43

Remove the small reflector and attach it to the probe.

그림 44

At this point, the Gamma axis of the near-field photometer probe is still at the 0-degree position. Slightly move the probe base and adjust the screws at points ① and ② to adjust the probe’s height and orientation. Position the probe so that the straight laser beam coming from the main axis hits the exact center of the mirror, and ensure that the reflected beam returns along the same path.

그림 45

그런 다음 프로브 브래킷 받침대를 나사를 사용하여 바닥에 고정합니다.

그림 46

Once secured, you may need to make minor adjustments to the probe’s height and orientation so that the straight laser beam continues to hit the exact center of the reflector and the reflected beam returns along the same path. After calibration is complete, ensure that all screws are tightened. Then remove the reflector and reinstall the light probe’s light shield.

참고: 프로브의 위치와 방향을 설정한 후에는 변경하지 마십시오. 변경하면 테스트 데이터가 부정확해질 수 있습니다.

②	Click to rotate the Gamma axis to a 90-degree position, so that the main-axis laser beam is directly aligned with the position where the crosshair laser is installed.

그림 53

Secure the crosshair laser to the triangular mount we provide.

그림 54

Turn on the cross-hair laser and use the direction of the single-line laser to roughly determine the position of the cross-hair laser.

그림 55

Fine-Tune the Position of the Crosshair Laser: The centerline of the straight laser should be perfectly aligned with the centerline of the crosshair laser. You can verify and adjust the position using the following method. Place a sheet of white paper at the exit of the crosshair laser and at the exit of the single-line laser. If the centerline of the single-line laser aligns with the centerline of the crosshair laser at both locations, you can confirm that the position and orientation of the crosshair laser are correct.

그림 56

그림 57

Next, secure the cross-laser tripod to the wall with screws. Once secured, you can still loosen the screws if necessary to make slight adjustments to the cross-laser’s position horizontally and vertically, ensuring it remains correctly aligned. After calibration, all screws should be tightened securely.

그림 58

그런 다음 감마 축을 0도 위치로 되돌립니다. 십자형 레이저 빔이 반대쪽 벽에 투사됩니다. 이렇게 하면 영구적인 표시가 생성됩니다. 즉, 십자형 레이저 빔이 이 방향으로 투사되면 고니오포토미터의 수평 및 수직 중심 위치가 표시됩니다. 이 표시는 교정 및 테스트 모두에 필요합니다.

6.1.2 Calibration of the Standard Light Direction

번호	주의 사항
①	스탠드 조명의 높이를 조절하려면 여기 있는 나사를 풀어주세요.
②	There are three screws here that allow you to adjust the pitch of the standard lamp.

그림 64

The standard lamp should be adjusted so that the cross-shaped laser beam is directed at the center of the small mirror, and the horizontal and vertical laser beams reflected from the mirror coincide exactly with the original cross-shaped laser beam.

그림 65

Based on our experience, follow these steps for calibration: First, adjust the height of the standard lamp to the appropriate position. The vertical reflected laser can be calibrated by rotating the calibration target, while the horizontal reflected laser can be calibrated by adjusting the pitch of the standard lamp. After calibration, the center height of the standard lamp may change, requiring you to readjust its height. Continue the reflection adjustment until the cross-shaped laser beam is projected onto the center of the small mirror, and the reflected horizontal and vertical laser beams perfectly align with the original cross-shaped laser beam.

Once the standard lamp is properly aligned, carefully remove the small reflector, taking care not to alter the alignment of the standard lamp while doing so. Then turn off the cross-hair laser.

Note: The test distance is the distance from the center of the Goniophotomoeter to the surface of the photometric probe. The distance calculated by the software should be close to the actual distance; an error of 1% or less is considered normal. If the error is too large, please refer to Section 2.3.1 to verify that the darkroom is functioning properly, and refer to Chapter 5 to review the calibration steps.

After calibration is complete, you can turn off the standard lamp using the software. Since the standard lamp becomes quite hot during use, wait for it to cool down before placing it back in its packaging for safe storage. Remove the calibration rod and store it properly.

7. Preparations Before Testing

7.1 Lamp Selection and Aging

Select representative luminaires for testing that comply with national or corporate standards; new luminaires must undergo aging treatment (for LED luminaires, a 24-hour aging period is recommended);

Check that the light fixture has no visible damage, that the internal wiring is connected correctly, and clean any stains from the surface of the fixture.

7.2 Introduction to Test Mode

C-Gamma Mode: Suitable for most lighting fixtures, such as streetlights, downlights, panel lights, and plant grow lights.

8.1 조명 설치 및 켜기

8.1.1 Light Fixture Installation

We have two C-Gamma test fixtures; this procedure uses the cross-shaped fixture as an example.

번호	주의 사항
①	Large cross-shaped clamps are used for various types of lighting fixtures
②	E27 Fixture for Testing Globe Bulbs

그림 77

Attach the fixture to the Goniophotomoeter. Turn on the wall-mounted cross-line laser and verify that the cross-line laser is projected accurately onto the marks made on the opposite wall.

그림 78

On the angle control interface, select the near-field photometer probe. Rotate the Gamma axis 90 degrees so that the crosshair laser points directly at the center of the crosshair fixture. Mount the luminaire under test onto the crosshair fixture. Adjust the position of the luminaire so that the crosshair laser is centered on the light-emitting surface of the luminaire under test, and the light-emitting surface is parallel to the crosshair fixture.

그림 79

Then rotate the Gamma axis back to 0 degrees. Loosen this screw by turning it counterclockwise.

그림 80

That is, move the spindle so that the light-emitting surface of the fixture aligns with the vertical laser beam of the crosshair, and then tighten the screw clockwise.

그림 81

Caution is required when installing directional lighting fixtures. When the angle of the C-plane on the Goniophotomoeter is 0 degrees, the light pole should point straight upward in accordance with streetlight installation standards, as shown in the figure below.

그림 81.1

When the angle of the C-plane on the goniophotomoeter is 0 degrees, the strip light should be installed vertically in accordance with industry standards, as shown in the figure below.

그림 81.2

8.1.1 Turning on the Lights

Connect the power cord to the luminaire under test. The connection method for the power cord of the luminaire under test is the same as that for the standard luminaire; refer to Section 6.1.1.

Adjust the cabinet switch according to the parameters of the luminaire being tested.

번호	주의 사항
①	If the sample luminaire is powered by AC, switch to the AC direction; if it is powered by DC, switch to the DC direction.
②	Internal/External Sampling Switch for Electrical Parameters. External sampling uses a four-wire configuration and provides more accurate voltage readings. Unless otherwise specified, set this switch to “External Sampling”; no further adjustments are necessary.

If you select constant voltage, enter the sample’s rated voltage, and set the current to the DC power supply’s maximum output current. 참고: DC 전원 공급 장치 모델이 다음과 같은 경우 DC3010, its maximum output voltage is 30 V and its maximum output current is 10 A.

그림 84

The software offers two methods for turning the sample lights on and off, and users can choose between them.

번호	주의 사항
①	If you check the “Auto-On” and “Auto-Off” options, the software will automatically power on the sample according to the selected power source and the entered electrical parameters when the test begins, and will automatically cut off the sample’s power when the test ends.
②	If the “Auto On” and “Auto Off” options are not checked, you can also click this button. The software will power on the sample based on the selected power source and the entered electrical parameters. Clicking this button again will cut off the power to the sample.

그림 85

8.2 Preheating Parameter Settings

번호	주의 사항
①	If you check the “Preheat” box, the software will preheat the luminaire according to the specified preheat parameters when the test begins, and will automatically start the test once preheating is complete. "예열" 확인란을 선택하지 않으면 소프트웨어가 즉시 테스트를 시작합니다.
②	예열 매개변수 설정

그림 86

Click “Preheat Parameter Settings.”

번호	주의 사항
①	Warm-up Duration Setting: The purpose of the warm-up is to allow the light fixture to remain on for a period of time until its luminous and color parameters stabilize, after which testing begins automatically.
②	Sampling interval: The software will automatically take samples at the set interval throughout the entire warm-up period to obtain real-time data. We recommend setting this to 5 seconds or longer.
③	If checked, the test will automatically skip the remaining warm-up time and begin once the light fixture has stabilized; if unchecked, the test will begin only after the warm-up period has been completed according to the set duration.
④	조명기구의 정상 상태 정의. 값이 20과 0.5%로 설정된 경우, 지난 20분 동안 해당 매개변수의 변동이 0.5%를 초과하지 않으면 조명기구는 정상 상태에 있는 것으로 간주됩니다.
⑤	조명기구의 안정성을 판단하는 데 소프트웨어가 사용할 매개변수를 선택할 수 있습니다. 광학적 매개변수, 전기적 매개변수 등이 있습니다.
⑥	The software will save the change curves for the selected parameters during the warm-up period in the test report.
⑦	Once you’ve finished configuring the settings, click OK to save and exit.

그림 87

8.3 테스트 매개변수 구성 및 테스트 시작

Click “Start Test.”

그림 88

Go to the test parameter settings screen.

번호	주의 사항
①	Lighting fixture types—indoor lights, outdoor lights, or plant grow lights—these three types of lighting fixtures are subject to C-Gamma testing.
②	Select whether the light fixture is symmetrical. Unless there are specific requirements, select the first option, “asymmetrical,” regardless of whether the light fixture being tested is symmetrical or not (to obtain the actual data for the light fixture).
③	C-plane angle range: Select 0 to 180 degrees; no modification is needed. For data ranging from 180 to 360 degrees, the software will automatically convert it to C-plane angle intervals. For symmetrical luminaires, such as indoor lights, you can select a larger interval, such as 30 degrees; for asymmetrical luminaires, such as streetlights, you can select a smaller interval, such as 10 degrees. The smaller the angle interval, the higher the test accuracy, but the longer the testing time. If time permits, it is recommended to select a smaller angle interval.
④	Gamma plane angle range: If the sample’s light irradiation angle exceeds 180 degrees (e.g., incandescent bulbs), select -180 degrees to 180 degrees; if the sample’s light irradiation angle is less than 180 degrees (e.g., panel lights), you can select an angle interval for the Gamma plane ranging from -90 degrees to 90 degrees. Unless there are special requirements, selecting 1 degree is sufficient. The specific angle interval selected here has no effect on test speed.
⑤	If the system has multiple photometric probes, please select the one you want to use.
⑥	Fixed Range: If you are consistently measuring the same type of light fixture and the luminous intensity data does not vary significantly, you can check this box to save time. However, if you have ample time or frequently test light fixtures with different luminous intensities, we recommend leaving this box unchecked so that the photometer can automatically select the appropriate range for each light fixture.
⑦	To set the monitoring angle during lamp warm-up, simply set it to (0, 0).
⑧	Normalization refers to the decision of whether to apply a uniform value to the first row of data in the luminous intensity table of a test report; certain standards, such as the U. S. streetlight standard, may require you to perform a similar adjustment. There are three options: no normalization, normalization to the maximum value (which slightly increases the luminaire’s total luminous flux), and normalization to the average value (which leaves the luminous flux essentially unchanged).
⑨	If you need to remove all stray light outside a specific angle, check this option and then enter the desired angle . For example: If you check this option and enter 60, the data outside ±60 degrees of the luminaire’s gamma plane will automatically be set to 0.
⑩	Enter the number of light sources in the luminaire and the rated luminous flux of each light source. If you do not know this information, you may leave it blank; it will not affect the test results.
⑪	샘플의 발광 표면 치수를 입력하십시오. 실내 조명 기구의 경우, 소프트웨어는 휘도 한계 곡선, UGR 및 기타 매개변수를 계산하기 위해 이 데이터가 필요합니다.
⑫	Enter information about the sample luminaire
⑬	시험 환경(예: 암실)의 온도와 습도를 입력하십시오.
⑭	Click OK to proceed to the warm-up screen, or to the test screen.
