The aging of led high voltage lamp strips should be a very important process in the test process, but it is often overlooked in many companies, can be properly effectively aging. The subsequent analysis of the LED itself includes all parameters such as brightness wavelength. Will be uncertain. Overcurrent impact aging is also a kind of aging method often used by manufacturers. Usually this type of aging is performed using a constant current source with adjustable frequency, adjustable current adjustable duty cycle, in order to judge the quality expectations of the LED in a short time life.

Ordinary led high-voltage lamp strips can be cut in different groups according to customer requirements. However, some customers will require a single LED strip to make a cutting position, which is also unreasonable. Because then it is equivalent to a parallel circuit, there is no guarantee for the service life of the LED strip. For full-color light strips, you can choose between 3 lights a light cut, 6 lights a cut. Each has a certain power supply standard difference, which is 5V power supply, 12V power supply, 24V power supply, some people in the industry also call this product low-voltage magic light bar.

    The led high-voltage lamp strip is mainly installed in the light trough to create a large area of light-emitting ceiling wall surface, which shapes the effect of washing the wall. It is precisely because of its large light exposure range that once a problem occurs, it will affect a wide range of light shadow effects. When we choose the LED light strip, we must brighten our eyes choose carefully. For good quality LED lamp beads, the brightness between the lamp beads the lamp beads is consistent, the light is uniform, the brightness of the head tail of the lamp belt must be the same. The light color of the light strip should also be consistent. Use white paper close to the light emitting surface of the light strip observe directly with your eyes. If the lamp has a uniform luminous effect, it is necessary to choose a good color rendering when buying, the color rendering index Ra> 80 is a requirement that a professional LED strip must meet.
