d) The safety level of lamps can be divided into four types:
Category 0 lamps: Non-ground lamps, relying on basic insulation as a lamp to protect against electric shock, which means that the accessible conductive parts of the lamp are not connected to the protective conductors in the fixed line of the facility, and if the basic insulation fails, they have to rely on Environment.
Class I lamps: There are ground lamps. The protection of lamps against electric shock not only depends on the basic insulation, but also includes additional safety measures, that is, connecting the accessible conductive parts to the protective grounding conductor in the fixed line of the facility, making it easy to touch. The conductive parts are not charged in the event of a basic insulation failure.
Class II lamps: Earthless lamps, protection against electric shock not only by basic insulation, but also with additional safety measures, such as double insulation or reinforcement, but no protective grounding measures or rely on installation conditions.
Class III lamps: Protection against electric shock depends on the supply voltage being a safety extra-low voltage (ac voltage less than 50V rms) and will not generate lamps with higher SELV voltages.

4, reliability test:
a) Temperature rise test, which measures the temperature of a particular component when the lamp is operating at its maximum power consumption under a specific temperature environment. In addition to the test components required for testing, the drive IC, lamp housing, LED (lamp foot or LED heat sink), etc. Parts are fixed measuring points. The recording is repeated every 30 minutes until the measuring parts are kept at a constant temperature. The recording includes the energizing time, the temperature of the measuring part, and the ambient temperature at that time. The record table is shown in Schedule II.
b) The switch-electricity test is based on the normal working conditions of the lamp, which is one minute and one thirty seconds off as a switching cycle. The switch test is performed continuously for 100 times, and the working conditions of the lamps are recorded.
c) The vibration test is to put the lamp on the vibration table for 30 minutes to inspect whether the parts of the lamp are loose or fall off and whether the lamp can work normally.
d) In the reliability test, check the function of the luminaire according to the luminaire operating instructions.
