How to judge the quality of energy-saving lamps
1. The safety of energy-saving lamps
To judge whether an energy-saving lamp is safe, take it in your hand and carefully observe 6 aspects: whether the lamp holder (iron or copper, aluminum) and the plastic part are tightly combined; whether the lamp tube and the plastic part of the lower shell are firmly combined; the upper shell plastic part Whether the card position with the lower shell plastic part is fastened, high
Whether it can be detached under temperature; whether the shell plastic parts are made of flame-retardant and high-temperature resistant (180℃) materials; whether the skeleton and circuit board in the electronic ballast circuit are made of flame-retardant materials.
Second, the service life of energy-saving lamps
The average life of good energy-saving lamp products is more than 5000 hours, and the average life of poor products is about 1000 hours.
The electronic ballast of an ordinary energy-saving lamp is composed of about 30 components. If one of the components is damaged, the energy-saving lamp cannot be lit. If the components of an electronic ballast are very good, but if the parameters are suitable If the matching is not good, the life of the electronic ballast will not be long. If the above two items are done well, but if the process control is not good, and the quality management control is not good, the above effort will be wasted even if it is done well.
3. Luminous flux, luminous decay and luminous efficiency of energy-saving lamps
The color temperature is 2700K and 6400K, which is a better choice for lighting source. Luminous flux: the sum of the amount of light emitted by the light source per second: used to indicate the amount of light emitted by the lamp tube, that is, the amount of light emitted. The general symbol ф indicates that the unit is lumens (Lm).
Luminous efficiency and luminous flux requirements: less than 15W, luminous efficiency requirement ≥ 45LM/W; greater than or equal to 15W, luminous efficiency requirement ≥ 60LM/W. Color rendering index: ≥ 80; color temperature: small color temperature deviation, good consistency; dynamic time: less than or equal to 1 second.
