3、 Detection range

This standard is applicable to the formulation of unified inspection items and inspection instructions for lamps produced by the company. This standard specifies the technical requirements, test methods, inspection rules, marking methods, packaging, transportation and storage conditions of LED lamps.

LED lamps refer to lighting lamps with LED as light-emitting device. Compared with traditional lamps with high-pressure sodium lamp and metal halide lamp as light source, they have the advantages of energy saving, environmental protection and long life.

4、 Inspection Description:

1. Reliability test:

a) Temperature rise test: measure the temperature of specific parts when the lamp is working at the maximum power consumption under a specific temperature environment. In addition to the parts to be tested according to the detection requirements, the driving IC, lamp shell, LED (lamp foot or LED heat sink) and other parts are fixed measurement points. Record every 30 minutes until all measuring parts are at constant temperature, including power on time, temperature of measuring parts and ambient temperature at that time. See attached Table II below for the record sheet.

b) Under the normal working conditions of the lamp, the switching power test is to open for 1 minute and close for 30 seconds as a switching cycle, carry out the switching test for 100 times continuously, and record the working conditions of the lamp.

c) The vibration test is to place the lamp on the shaking table and vibrate for 30 minutes to check whether all parts of the lamp are loose and fall off, and whether the lamp can work normally.

d) During the reliability test, the functional items of lamps shall be inspected according to the operation manual of lamps.

2. Electrical parameters:

a) DC power supply lamps controlled by external power supply: voltage and current measured by Voltmeter and ammeter.

(Note: to measure the current, it is necessary to measure the current of LED single lamp and single color, which is recorded in attached table 1)

b) AC powered lamps with built-in power control: measure the voltage, current, power, power factor and other parameters of lamps with digital power meter.

c) Class I lamps must be tested for electrical strength, leakage current and insulation resistance. The electrical strength is the breakdown phenomenon between 220V terminal and 1500V shell for 1min. Leakage current ≤ 1.0mA. Insulation resistance ≥ 2m Ω.

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

Class 0 lamps: lamps without ground wire, which rely on basic insulation as anti electric shock protection, which means that the accessible conductive parts of lamps are not connected to the protective conductor in the fixed line of the facility. In case of basic insulation failure, they have to rely on the environment.

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

Class II lamps: ground free lamps. The protection against electric shock is not only based on the basic insulation, but also has additional safety measures, such as double insulation or reinforcement, but there is no protective grounding measures or depends on the installation conditions.

Class III lamps: the protection against electric shock depends on the power supply voltage, which is a safe ultra-low voltage (the effective value of AC voltage is less than 50V), and will not produce lamps higher than SELV voltage.
