Keywords: energy saving lamp failure rate life
I. Overview
In the practical application of energy-saving lamps, there will be two problems such as the length of ignition time of Qihui and the amount of damage during the ignition process. The energy-saving lamp Qihui ignition application time - the life, the number of damage - is the failure rate.
Failure rate and life are two interrelated physical quantities that characterize energy-saving lamps and their technical quality. The two physical quantities, failure rate and lifetime, are both related and independent. In the lighting industry and users, the two are often confused or equivalent due to lack of scientific and correct understanding.
Second, the life of energy-saving lamps
Lifetime: It is a physical quantity that characterizes the light source and can reliably start the ignition time in the actual use of the space environment and the power grid environment. Usually measured in hours (h).
The concept of life has three in the lighting industry.
Qihui igniting life: refers to the time when the light source is ignited from Qihui to extinction. The end user usually understands the life of the light source in this way.
Average life expectancy: refers to the weighted average time of a batch of light sources, from ignition to extinction. The average life expectancy is usually used for sampling and evaluation, the life of a certain source of a certain type of product, a certain type of light source.
Effective life: refers to the time from the ignition of the ignition to the decay of the luminous flux to a specified value. Here, the meaning of "a certain prescribed value" is that the luminous flux is attenuated to several tens of percent of the initial value, that is, X%.
At this stage, the "a certain value" of the effective life of the light source is defined. The general rule is that the luminous flux is attenuated to fifty percent (50%) of the initial value.
Therefore, the effective life of the light source is defined as: the light source is ignited from the ignition to the attenuation of the luminous flux to fifty percent (50%) of the initial value, that is, it is recognized as the end of life.
Third, the technical factors affecting the life of energy-saving lamps
The end of the life of the energy-saving lamp is because the effective performance of the electronic components and devices constituting the energy-saving lamp is exhausted, or the effective performance of the fluorescent material (such as phosphor) is exhausted.
The speed at which electronic components, devices, and fluorescent tubes are depleted of effective performance. Subject to the following four technical factors:
One is: the technical quality of fluorescent powder, electronic powder, and luminescent gas used in fluorescent tubes, and the technical level of production technology.
The second is: the technical quality level of the electronic element, the technical parameters of the device, the reliability level, and the technical level of the production process for the electronic element and device screening.
The third is: the technological advancement of electronic ballast technology, technical quality and other technical factors. For example, AC-DC-AC (AC-DC-AC) conversion frequency has a high impact on the life of energy-saving lamps. The high conversion frequency is excellent, low and bad.
The fourth is: the matching of technical parameters between the fluorescent tube and the electronic ballast. The matching is reasonable, and the technical quality of the energy-saving lamp is excellent and the service life is long.
At present, according to the technical quality level of fluorescent lamps in China, and the technical quality level of electronic components and devices. The energy-saving lamp with excellent technical quality is the ignition life of the whole lamp, which should be 15,000 hours - more than 20,000 hours.
Fourth, the failure rate of energy-saving lamps
The failure rate is a physical quantity that characterizes the energy-saving lamp. In a certain period of time, due to the technical factors such as the electronic components of the energy-saving lamp, the technical quality of the fluorescent tube, and the technical performance of the whole lamp, the energy-saving lamp cannot ignite the quantity. .
Measuring the failure rate of an energy-saving lamp is usually described by the percentage (%).
The failure rate of energy-saving lamps is subject to the technical factors of the following three aspects.
First: the energy-saving lamp production enterprise, the technical strength of scientific research and development;
The second is: energy-saving lamp production enterprises, production technology level;
The third is: the technical quality of electronic components, devices and fluorescent tubes used by energy-saving lamps manufacturers.
At this stage, the energy-saving lamp failure rate. The differences between various production companies and products are relatively large. The failure rate of energy-saving lamps with excellent technical quality is within 5%, which should be a reasonable range.
However, some of the inferior energy-saving lamps on the market, especially the energy-saving lamps produced by means of copying PCB boards. The failure rate is as high as 20-30%, and even more than 50%. What is even more is "Week Light" and "Half Moon Light".
V. Method for identifying failure rate and life of energy-saving lamps
To truly identify the failure rate and life of energy-saving lamps, it is not possible to do a test in the laboratory. Rather, it is necessary to pass the actual application of the space environment and the grid environment to verify the quality of the energy-saving lamp failure rate and life.
In the actual purchase, the most direct identification method:
1. Identify the wide voltage withstand of the energy-saving lamp: Connect the energy-saving lamp to the auto-coupler, and place the energy-saving lamp in three voltage states of 180V, 220V and 260V, respectively, and ignite for 24 hours. Take a look at whether the energy-saving lamp Qihui ignition is stable and reliable.
2. Identify the adaptability of the energy-saving lamp to the application environment: put the energy-saving lamp in the application space of -15 ° C - 10 50 ° C, respectively, in the three voltage states of 180V, 220V, 260V, each ignited for 24 hours. Take a look at whether the energy-saving lamp Qihui ignition is stable and reliable.
3. Understand the application cases of energy-saving lamps and visit them to understand the application:
Pay special attention to the cases that have been applied.
(1) Is there a practical example of a power grid environment where voltage drops are severe and harmonics are severe? Such as high-power AC, DC resistance welding machine production workshop; high-current AC welding machine production workshop; steel company rolling mill workshop.
(2) There are practical examples of applications in high temperature and high humidity environments, such as steelmaking foundry, rubber molding workshop, oil extraction workshop, food production workshop, etc.
Conclusion
1. Failure rate and life are two interrelated physical quantities that characterize energy-saving lamps and their technical quality. The energy-saving lamp Qihui ignition application time - the life, the number of damage - is the failure rate.
2. At present, according to the technical quality level of fluorescent lamps in China, and the technical quality level of electronic components and devices. The energy-saving lamp with excellent technical quality is the ignition life of the whole lamp, which should be 15,000 hours - more than 20,000 hours.
3. At present, the failure rate of energy-saving lamps with excellent technical quality is within 5%, which should be a reasonable range.
4, to truly identify the failure rate and life of energy-saving lamps, is not done in the laboratory to do a test. Rather, it is necessary to pass the actual application of the space environment and the grid environment to verify the quality of the energy-saving lamp failure rate and life.
