Reflective LED lamp is better than traditional halogen tungsten lamp

The testing results show that the optical efficiency index most reflective self ballasted LED light than in the past has been greatly improved, reached a level of about 60lm/W, compared with the traditional halogen reflector lamps, increased by about 3 times, two lamp lumen maintenance light in 4000 hours when the difference is not big, but there are obvious the difference rate of change trend of maintaining lamp lumen maintenance, light flux rate has exhibited significant difference at 6000 hours.

The reflection type self ballasted LED lamp uses LED as the light source, which is mainly used to replace the traditional halogen lamp. Compared with the halogen reflector lamp, the light efficiency of the reflection type self ballasted LED lamp is greatly improved. The reflection type self ballasted LED lamp, the national development and Reform Commission, Ministry of housing and urban rural construction, Ministry of transport, three ministries in August 30, 2010 released the change ring [2010]2082 file, launched a semiconductor lighting application demonstration project, including covering the reflection of self ballasted lamp LED 20 semiconductor indoor lighting project; China Quality Certification Center in December 2010 officially released CQC3129-2010 "reflective self ballasted technology standard" LED "certification and CQC31-465137-2010 energy-saving lamp reflective self ballasted LED lamp energy saving certification rules", launched for reflection type energy-saving certification self ballasted lamp LED. By the national electric light source quality supervision and Inspection Center (Beijing) and so on the drafting of the development of the "reflection of the self ballasted LED lamp performance requirements" and "reflection of the self ballasted LED lamp performance test method" two national standards have been submitted for approval. LED lighting products technical status quo and prospects for the development and application based on the consideration of the national electric light source quality supervision and Inspection Center (Beijing) research on detection and evaluation has long been committed to LED lighting products including a reflective self ballasted LED lamp, the following will be for reflection type self ballasted LED lamp described from the light effect, luminous flux to maintain the rate and temperature characteristics of several aspects.

Optical efficiency index increased significantly

The light effect is one of the important indexes to evaluate the performance and energy saving effect. The testing results show that the optical efficiency index most reflective self ballasted LED light than in the past has been greatly improved, reached a level of about 60lm/W, compared with the traditional halogen reflector lamps, increased by about 3 times, lighting design and reasonable application will reflect the energy saving effect of the corresponding. On the other hand, it should be noted that the light effect and the initial color parameters of the lamp are only part of the parameters that represent the initial performance of the lamp, and the performance of the lamp can not be evaluated comprehensively.

Under this condition, as a kind of lighting products with LED light source, the maintenance performance of light flux and color parameters is also an important indicator. The test results showed that two kinds of lamp lumen maintenance light in 4000 hours or less, but there are obvious differences in rate trends to maintain the lamp lumen maintenance, light flux rate has exhibited significant difference at 6000 hours. The performance indicators and the performance of the lamp will directly affect the service life of the lamp, therefore, in the performance evaluation of the lamp, the light of the lamp and the color of the long-term maintenance of indicators to be taken seriously.

Attention should be paid to heat dissipation design of compact products

Temperature is another important factor affecting LED lighting products, the reflection type self ballasted LED lamp with the small size of the compact LED lighting products especially, and the lamp installation environment is easy to improve the ignition temperature of the lamp working environment, which may affect the performance of the lamp. In order to evaluate the influence of the ambient temperature on the performance of the reflected self ballasted LED lamp, a variety of lamp samples should be collected for testing. According to monitoring of the lamp shell temperature results in different light environment temperature: different light samples affected by the thermal structure design and other factors, there are some differences between the shell temperature of the lamp (maximum lamp shell temperature difference of 8 degrees Celsius), lamp shell temperature and the ambient temperature is basically linear light.

Comparison of different ignition temperatures of lamp shell temperature and light parameter test results are visible, along with the change of ignition temperature, the lamp light parameters showed different trends, should be considered in the light of the performance evaluation and the corresponding application of lighting design to do. But it should be noted that there is no direct relationship between the temperature of the lamp shell and the optical parameters of the lamp.

The performance evaluation index of reflection type self ballasted LED lamp comprises a plurality of initial characteristics, maintain the temperature characteristics, including luminous flux, luminous efficiency, light intensity and other optical center parameters and chromaticity characteristics of lamp lamp performance influenced by the selection of parts performance, it is also influenced by the overall structure design of the lamp. In the performance evaluation and the use of lighting design, should take into account the various factors to ensure the good application effect of the lamp.
