The test results showed that compared to the past most of the reflective self-ballasted LED Floodlight 80W luminous efficiency indicators improved significantly, reaching a level of 60lm / W, compared with traditional halogen reflector lamps, increase about three times two lamp lumen maintenance is little difference in the ignition 4000 hours lamp lumen maintenance there are significant differences in the rate of change in trend at 6000 hours, the lamp lumen maintenance rate showed significant differences.
Reflective self-ballasted LED lights to LED as light source, at this stage is mainly used to replace conventional halogen reflector lamps. Compared with the halogen reflector lamps, the luminous efficiency of reflective self-ballasted led driver 120w lights have a more substantial increase. For reflective self-ballasted LED lights, the National Development and Reform Commission, Housing and Urban-Rural Development Ministry, the Ministry of Transport ministries in the August 30, 2010 Development and Reform Office of Environmental and Resources  2082 document, launched a semiconductor lighting products, application and demonstration projects, including covering the reflective semiconductor 20 self-ballasted LED lights indoor lighting application projects; China Quality Certification Center has officially launched in December 2010 CQC3129-2010 "reflective self-ballasted LED lamp energy saving certified technical specifications and CQC31-465 137-2010 "reflective self-ballasted LED lights energy-saving certification rules, start a reflective self-ballasted LED lights energy-saving certification. Drafted by the National Electric Light Source Quality Supervision and Inspection Center (Beijing) to develop "reflective self-ballasted LED lamp performance requirements" and "reflective self-ballasted LED lamp performance test methods," the two national standards have also been submitted for approval. Based on the current situation and development of LED lighting products and application prospects of consideration, the National Electric Light Source Quality Supervision and Inspection Center (Beijing) has long been committed to reflective self-ballasted LED lights, including LED lighting products, testing and evaluation studies, the following will aspects of light efficiency, lumen maintenance and temperature characteristics described for reflective self-ballasted LED lights.
Luminous efficiency indicators significantly improved
The luminous efficiency is one of the important indicators for evaluation of lamp performance and energy saving effect. The test results showed that compared to the past most of the reflective self-ballasted LED lamp luminous efficiency indicators improved significantly, reaching a level of 60lm / W, compared with traditional halogen reflector lamps, increase about three times reasonable lighting design and application will reflect the energy saving effect. On the other hand, need to be aware of the effect of light and the initial color parameter is only part of the initial characterization of lamp performance parameters, and not a comprehensive assessment of the performance of the lamp.
Under these conditions, is also important to maintain performance as an LED Power Supply light source lighting products, light flux and color parameters assessment indicators. The test results show that the two lamp lumen maintenance in the ignition of 4000 hours or less, but the lamp lumen maintenance there are significant differences in the rate of change in trend to 6000 hours lamp lumen maintenance rate showed significant differences. Light of such performance indicators and performance will directly affect the life of the lamp, therefore, to evaluate performance of the lamp, the long-term maintenance of response to the lamp luminous flux and color index attach importance to.
Compact product should pay attention to thermal design
Temperature is another important factor for LED Flood light 10W lighting products, reflective self-ballasted LED lights this small volume compact LED lighting products, even more so, and this lamp installation environment is also easy to improve the light lighted the work of the ambient temperature, which may affect the use of the lamp performance. Ambient temperature for the assessment of ignition performance impact of reflective self-ballasted LED lights need to collect a variety of light samples for testing. Different ignition ambient temperature on the lamp housing temperature monitoring: a different light sample by the thermal structure design and other factors, the case temperature of the lamp there are certain differences (maximum lamp housing temperature difference of about 8 ℃), the lamp housing temperature a linear relationship between ambient temperature and fire.
Comparison of different ignite environment temperature under the light of the case temperature and optical parameters of the test results can be seen, with the changes in the lighted environment temperature of the optical parameters of change of the lamp showed different trends, should be in the right light conduct performance evaluation and the appropriate lighting applications designed to do full consideration. But should also be noted that no direct correspondence between the optical parameters of the lamp housing temperature and light, light performance will not be evaluated directly from the lamp housing and low temperature.
Reflective self-ballasted LED Spotlight 30W performance evaluation, including initial characteristics to maintain the characteristics, temperature characteristics, the specific luminous flux, luminous efficiency, the center of light intensity and other optical parameters and the chromaticity characteristics of the performance of the lamp by light the selected component performance constraints, while by the light of the overall structure of the design. Performance Evaluation and lighting design in the right light, you should consider various factors, in order to ensure good application effect of the light.
