Judging whether a energy-saving lamp is good or bad, the professional suggests that it can be considered from the following aspects.
First, security. To judge whether an energy-saving lamp is safe, it is necessary to carefully observe six aspects in the hand: whether the combination of the lamp head (iron or copper, aluminum) and the plastic part is tight; whether the combination of the lamp tube and the plastic part of the lower case is firm; the upper shell plastic part Whether the clamping position of the lower shell plastic parts is tight, whether it can be detached at high temperature; whether the outer shell plastic parts adopt flame retardant and high temperature resistant (180 ° C) materials; whether the skeleton and circuit board in the electronic ballast circuit are made of flame retardant materials.
Generally, good energy-saving lamps and products use PBT flame-retardant and high-temperature resistant materials. ABS plastics are generally used. The plastics begin to deform at a normal temperature of about 90 °C, and the flame retardancy is not good, which is easy to cause fire.
Second, the service life. The average life expectancy of good energy-saving lamps is more than 5000 hours, and the average life of poor products is about 1000 hours.
An energy-saving lamp was dissected and found to consist of a tube and an electronic ballast. The life of a lamp has a very strong relationship with raw materials, manufacturing processes, manufacturing equipment, and quality control and assurance systems.
An ordinary type of energy-saving lamp electronic ballast consists 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, if the parameters are suitable. If the distribution is not good, the life of the electronic ballast will not be long. If the above two items are well done, if the process control is not good and the quality management is not well controlled, even if the above work is done well, it will be in vain.
Third, luminous flux, light decay and light efficiency. This is a three indicator that reflects whether an energy-saving lamp product has energy-saving effects.
