The Led E27 Lamp holder refers to the interface connected to the end of the electric light wire for installing the bulb. It should be used with caution. Electric light sources mainly use the naming method of lamp caps and lamp holders. What is the test method for Led E27 Lamp holder? Let's take a look together next.
Here is the content list:
Light decay and life test
Main light parameters of the E27 Lamp holder
E27 Lamp holder aging method Lamp holder aging is carried out in an environment where there is no forced ventilation and the temperature is controlled at 20℃-30℃. The lamps are erected in a normal installation posture, and they are connected according to the nominal rated voltage of the lamp or the maximum voltage of the nominal applicable voltage range. Power supply, the lamp works at full power. During the aging process, the lamps should be turned off no less than 2 times every 24h, each turn-off time should be 25-35min, and the interval time should be at least 30min. The number of samples is not less than 3 sets. During the test, the lamp shall not have any failure or burnout, otherwise, it will be unqualified.
E27 Lamp holder's luminous decay and life measurement method replaces the luminous flux method with the illuminance method. The horizontal illuminance value is measured at the center point at a distance of 2 meters from the lamp height and one point at a distance of 1 meter on the axis along the road. A total of 5 are measured. The point, compare with the initial value of each point and get the average maintenance rate value of 5 points. Between 2000-5000h, the average maintenance value is measured every 336h interval; if the lamp still meets the requirements at 5000h, the illuminance value of each point at 2000h is the initial illuminance value, and the measured illuminance value for every 336h interval is equal to the corresponding initial illuminance value at 2000h is compared and the average maintenance rate is obtained. From the average maintenance rate fitting curve of the above 10 points, the lifetime when the average maintenance rate is 75% plus 5000his the life of the E27 Lamp holder. Select one of the E27 Lamp holders, and measure the luminous flux at 0-2000h with the photometric distribution test method, and calculate the 2000h luminous flux maintenance rate as the calibration value. When measuring the illuminance, the ambient temperature should be controlled at 25℃±1℃ and stable for more than 3h.
The average color temperature and average color rendering index are measured with an integrated spectrum test system at an ambient temperature of 25℃±1℃, rated voltage, and rated frequency. The Led E27 Lamp holder sample is placed in the integrating sphere to avoid direct light from entering the test probe. The outer surface of the Led E27 Lamp holder should be pasted with a white cover film that does not significantly affect the color temperature test. Test after 1h ignition.
E27 Light Lamp holder's luminous efficiency and light distribution curve are measured with a photometric distribution test system at an ambient temperature of 25℃±1℃. First, test the luminous flux and light intensity distribution, light distribution curve, etc. of the E27 Light Lamp holder, and the ratio of the luminous flux of the E27 Light Lamp holder to the actual power consumption of the lamp.
