General lighting AC 50V or DC 120V or below LED lamp testing
[ 11-27-2024 ]
For LED lamps with AC 50V or DC 120V or below for general lighting, the detection methods mainly include the following aspects:
1. Electrical safety performance detection
Voltage resistance test: By applying a voltage higher than the rated voltage of the LED lamp, test whether its insulation performance is good to prevent the risk of electric shock.
Insulation resistance test: Measure the insulation resistance value of the LED lamp to ensure that it meets the specified safety standards.
Leakage current test: Detect whether there is abnormal leakage current when the LED lamp is working normally to ensure its electrical safety.
2. Light efficiency detection
Brightness test: Use a brightness meter to measure the brightness of the LED lamp and evaluate its lighting effect.
Luminous flux test: By measuring the luminous flux emitted by the LED lamp and combining its input power, the luminous efficiency (i.e. the ratio of light output to electrical power) is calculated to measure the energy-saving performance of the lamp.
Color temperature test: Use a color temperature meter to measure the color temperature of the LED lamp and evaluate its light color performance.
Luminous efficiency test: Calculate the luminous efficiency based on brightness and power to evaluate the energy efficiency of the LED lamp.
3. Color rendering test
Color rendering index test: It is carried out through the standard color sample irradiation experiment. The color rendering index (Ra) reflects the ability of light to restore the color of objects. The color rendering index of excellent LED lamps should be higher than 80.
4. Life evaluation
Accelerated aging test: By simulating the environment in which LED lamps work for a long time, the aging process is accelerated to evaluate the life of the lamp. This includes the light decay test of LEDs to ensure that the lamps maintain good performance within the design life period.
5. Temperature rise test
Surface temperature test: Check whether the surface temperature of LED lamps meets the standard requirements under normal working conditions to avoid safety hazards caused by overheating.
6. Other test items
Appearance inspection: Check whether the outer shell, lamp beads and other components of the LED lamp are intact and whether there is any physical damage.
Package form detection: Detect the packaging form of the LED lamp, such as SMD, COB, etc.
Lamp bead quantity detection: Detect the number of lamp beads of the LED lamp to evaluate its light intensity.
Drive mode detection: Detect the drive mode of the LED lamp, such as constant current drive, PWM drive, etc.
Protection level detection: Detect the protection level of LED lights to evaluate their waterproof and dustproof properties.
Radiant heat measurement: Measure the radiant heat of LED lights to evaluate their heat dissipation performance.
Mirror effect evaluation: Evaluate the mirror effect of LED lights, such as reflection efficiency.
Light color consistency detection: Detect the light color consistency of LED lights to evaluate their light uniformity.
Installation method detection: Detect the installation method of LED lights, such as hanging, wall mounting, etc.
Dimension measurement: Measure the size of LED lights to evaluate their applicability.
Explosion-proof level detection: Detect the explosion-proof level of LED lights to evaluate their applicable environment.
VII. Description of detection method
Voltage test: Use a digital multimeter to measure the working voltage of LED lights.
Current test: Use a digital multimeter to measure the working current of LED lights.
Power test: Use a power meter to measure the power of LED lights.
Fault detection: Use a fault detector to detect whether the LED light has a fault.
In summary, for LED lamps with AC 50V or DC 120V or below for general lighting, the testing methods cover electrical safety performance, light efficiency, color rendering, life, temperature rise and many other aspects. These testing methods ensure that the LED lamps meet the specified standards in terms of safety, performance and applicability.
