LED lighting products photoelectric colour performance test method research

In recent years, with the continuous development of the led technology, high power semiconductor lighting devices in the in recent years obtained the rapid development, especially the white light power and efficacy constantly improve, led gradually entered the lighting field, caused a new lighting technology revolution. LED by different ways to arrange a combination and optical design, formed a variety of LED lighting products, and LED lighting products research, development in China is carried out in LED lighting products, the performance level also in gradually improve. In the correct test method under the premise of LED lighting products accurate measurement of photoelectric color performance parameters is scientific evaluation product performance and quality situation and the development trend of the foundation. LED lighting products in photoelectric colour performance testing present situation, the author in this paper centers in the test LED products work, the accumulation of LED lighting products colour performance of photoelectric detection method combing and summarized.

A, LED lighting products performance of the general evaluation

1. The classification of LED lighting products

At present, the LED lighting products mainly divided into LED lighting lamps and lanterns (for example: LED lamps and lanterns, LED light road for lamps and lanterns, embedded LED lamps and lanterns, LED tunnel lamps and lanterns, LED adornment lamps and lanterns, LED lamp) and traditional lighting source substitute LED lamp (for example: since ZhenLiu LED lamp, MR16, PAR lamp, fluorescent T8 / LED straight form T12, etc.). LED lighting lamps and lanterns is including based on LED components and matching drive, match light components, fixed and protection of the light emitting components components and instruments to the branch circuit components connect full lighting apparatus. LED lighting and can be divided into the integral LED lights and integral LED lamp two kinds......

B, the LED lighting products photoelectric colour performance test methods

Because at present about LED lighting products thermal characteristics of the characteristics and reliability, service life of the relevant standards are seminars and drafting, so this paper mainly discussed the LED lighting products photoelectric colour performance test methods. LED lighting lamps and lanterns below points and LED lights two series to discuss. View more......

C, Summarizes

LED lighting products photoelectric color performance parameters can be used to measure the distribution or integral system measurement indicates the ball, also can use collocation. Depending on the specific choice which method for measurement of the amount (color characteristic, light properties), product size and other request. Overall, equipped with auxiliary lights points for measuring the system integration LED lamp and the relatively small size of the characteristics and LED lamps and lanterns light color characteristic parameters. The advantages of the system integration test is a measure of fast, and you don't need to dark room. Distribution provide light intensity distribution photometric and total flux measurement method, it can measure the larger LED lighting products, of course, can also be used to measure the small size LED lighting products. Pay attention to test environment requirement, air flow may affect more sensitive to temperature measurement of LED lighting products. Using photometric method shall pay attention to the correct distribution nipped positioning. Installed in the distribution of high precision photometric spectrum radiometer don't through a mirror reflects the direct measurement of color space distribution. And integral ball, compared with photometric measure a fee time distribution. In the correct test method by reasonable choice premise, test methods to measure accurately LED lighting products color performance parameters, for photoelectric science evaluation LED lighting products performance quality situation and development trend data provide support.
