4. Inspection instructions:

  ⒈Electrical parameters:

  ⑴DC powered lamps controlled by external power supply: voltage and current measured by voltage and ammeter. [Note: To measure current, you need to measure the current of a single LED lamp and a single color and record it]

  ⑵ AC lamps with built-in power control: use a digital power meter to measure the voltage, current, power, power factor and other parameters of the lamp.

   (3) Class I lamps must be tested for dielectric strength, leakage current, and insulation resistance. The electric strength is the breakdown phenomenon of 220V terminal and 1500V, 1MIN. Leakage current≤1.0MA. Insulation resistance ≥ 2MΩ.

        Night light detection

  ⑷The safety level of lamps can be divided into four types:

   Class 0 lamps: non-ground wire lamps, relying on basic insulation as protection lamps against electric shock. This means that the accessible conductive parts of the luminaire are not connected to the protective conductor in the fixed line of the facility, and in case the basic insulation fails, it has to rely on the environment.

Class I lamps: lamps with a ground wire. The electric shock protection of lamps not only relies on basic insulation, but also includes additional safety measures, that is, connect easily accessible conductive parts to the protective grounding conductor in the fixed line of the facility to make it easy to reach The conductive parts in the basic insulation will not be charged in case of failure of the basic insulation.

   Class II lamps: non-ground wire lamps, anti-shock protection not only depends on basic insulation, but also has additional safety measures, such as double insulation or reinforcement, but there is no protective grounding measure or depending on installation conditions.

   Class III lamps: Anti-shock protection depends on the power supply voltage being a safe and extra-low voltage (the effective value of AC voltage is less than 50V), and it will not produce lamps with a voltage higher than SELV.

  ⒉Optical performance parameters:

  ⑴Light intensity <CD>: Light intensity distribution curve, iso-light intensity curve, and light intensity distribution data table can all be measured with a Goniophotometer.

  ⑵Luminous flux <LM>: The total luminous flux and effective luminous flux are subject to the test data of the spectrum analysis system. The area luminous flux table and the ring-belt luminous flux table can be measured with a Goniophotometer.

   (3) Illuminance <LUX>: Illuminance distribution and iso-illuminance curve can be measured with a Goniophotometer.

  ⑷Color temperature <K>: It can be measured with a spectrum analysis system.

  ⒊Structure appearance:

  ⒋Reliability test:

⑴Temperature rise experiment, measure the temperature of specific components when the lamp is working with great power in a specific temperature environment. In addition to the components to be tested according to the inspection requirements, the driver IC, lamp housing, LED (lamp pin or LED heat sink) and other components It is a fixed measuring point. Record every 30 minutes until the temperature of each measuring component is constant. The recording includes the power-on time, the temperature of the measuring component, and the ambient temperature at the time.

  ⑵The electrical switch experiment is under the normal working conditions of the lamp, turn on for 1 minute and turn off for 30 seconds as a switching cycle, according to which the switch experiment is performed 100 times continuously, and the working condition of the lamp is recorded.

   (3) The vibration test is to place the lamp on a vibrating table and shake for 30 minutes to check whether the parts of the lamp are loose or fall off, and whether the lamp can work normally.

  ⑷In the reliability test, check the function items of the lamp according to the lamp instruction.
