All other operations are exactly the same as those for Integrating Sphere; please refer to Section 5.2.

6. 테스트

6.1 Integrating Sphere Test

6.1.1 Calibration Verification

Refer to Section 5.1 to determine whether recalibration is necessary.

6.1.2 샘플 설치

When the stage is mounted at the bottom, the sample’s light-emitting surface should face upward; when the stage is mounted at the top, the light-emitting surface should face downward—it must not face to the side. Use the crosshairs as a reference to adjust the sample’s position so that its light-emitting surface is exactly in the center of Integrating Sphere. Secure it firmly with screws or clamps to prevent it from falling during testing.

If the sample is an E27 light bulb, it can be mounted directly onto the stage or mounted onto the stage using an E27 adapter; no power cord is required. See Figure 6-1.

그림 6-1

If the sample is a linear light fixture, a linear light fixture clamp may be installed and used, as shown in Figure 6-2.

그림 6-2

For other samples, place them directly on the stage or secure them with screws; the stage is equipped with M6 screw holes. Ensure that they do not fall off; see Figure 6-3.

그림 6-3

Connect the power cord to the two POWER terminals on the stage; the two SENSE terminals do not need to be connected. If using a DC-powered lamp, be sure to connect the positive and negative terminals correctly.

After installation, turn off the crosshair laser and Integrating Sphere. If your device includes two Integrating Sphere, make Integrating Sphere are turned off at the same time.

6.1.3 Cabinet Power Switching

If the sample is powered by DC, set the AC/DC switch on the cabinet to the DC position; if the sample is powered by AC, set the AC/DC switch on the cabinet to the AC position.

6.1.4 Verification of the Self-Absorption Coefficient

Integrating Sphere testing relies on diffuse reflection from the Sphere’s walls to take measurements. Therefore, if the sample is a relatively large luminaire, “self-absorption” may occur—that is, some of the diffuse reflected light is absorbed by the luminaire itself—which can cause deviations in the test results. Bare light sources and small luminaires can be tested directly; for larger luminaires, an Auxiliary Lamp must be used for correction, as shown in Figure 6-4.

번호	주의 사항
①	Click “Self-Absorption Coefficient”
②	For bare light sources or small luminaires, select “Do not use an auxiliary light for correction,” which corresponds to a correction factor of 1. For larger luminaires, select the appropriate correction factor from the drop-down list. If no correction factor has been generated for this sample previously, you will need to use an auxiliary light to generate a new correction factor; please refer to Chapter 8.
③	After selecting the correct auxiliary light correction factor, click “OK” to exit this page.

그림 6-4

Note: Even if the software or computer is shut down, the software will still use the last self-absorption coefficient by default the next time it is opened. Therefore, you must verify that you are using the correct self-absorption coefficient before each test.

6.1.5 Verification of Power Parameters via Software Navigation

8. Generation of the Self-Absorption Coefficient (Use of an Auxiliary Light)

8.1 Scenarios for Using Auxiliary Lights

For larger luminaires, the issue of self-absorption may arise. If a correction factor for the auxiliary light has not been generated previously, you must first generate the correction factor using the auxiliary light before conducting the test. Self-absorption is related to the luminaire’s housing dimensions, shape, color, and other factors; therefore, the self-absorption coefficient varies for different luminaires.

Note: The darker the color of the luminaire and the larger its size, the more severe the “self-absorption” issue becomes. Users can gain practical experience regarding whether to apply an auxiliary light correction factor. For example, for certain small luminaires, if the correction factor obtained after applying the auxiliary light correction factor is 1.02, this indicates that the luminous flux test result will increase by 2% after applying the correction factor; For example, for certain large luminaires, if the correction factor obtained after applying the auxiliary light correction is 1.13, this indicates that the luminous flux test result will increase by 13% after applying the correction factor.

8.2 Installation and Wiring of Auxiliary Lights

① Remove the plug from the opposite side of Integrating Sphere large Integrating Sphere to prepare for installing the auxiliary light fixture; see Figure 8-1.

그림 8-1
