There are four major factors affecting the life of LED exposed luminous word

With the rise of LED exposed luminous character in many cities, many people begin to pay attention to and discuss the real service life of LED exposed luminous character, and what are the reasons affecting the life of LED luminous character?

LED exposed luminous character is also called LED punching luminous character, which refers to the use of zinc plate, aluminum plate and other panels as the font substrate, through the substrate cutting, punching, paint, installation of LED light source and the font stroke assembly welding and formed by the luminous sign. What is the reason that will affect the life of LED words?

1. Improper installation of LED word

Normal manufacturers LED the service life of the theory of general for about 80000 hours, and now a lot of the actual installation of lighting or luminous word wiring is not professional, can appear uneven power, or power distribution is not uniform, wire used as a line or a finer, over the long term, the impact of the current to the LED lamp bead is bigger, makes the increasing of dead point and droop and uneven brightness.

2. The finished product of LED luminescent word should go through MOCVO growth epitaxial film, and then through a series of technological processes such as thinning, segmentation, solid crystal, welding line, package long baking, detection and color splitting to determine the service life of LED resin word; We often hear that leds have a lifetime of 100,000 hours; Not all leds last very long, and it's unlikely they won't break.

3, choose a poor LED lamp bead chip, color attenuation is very fast

The color that just installed good luminous word sends out is pure and bright, can use color to come down obviously less than a year, let font become red not red, green not green very ugly; The color is uneven and the color difference is obvious: the color difference is mainly shown in the large size luminous words made by pure white LED, which is not obvious in the assembly of a single light string, but obvious after the whole font is assembled.

4, part of the font stroke, the whole suddenly not bright or not bright: after a period of use of the luminous word, the local or the whole font light source began to flicker, sometimes bright, sometimes not bright, until completely not bright; Font output power is large, energy saving is not obvious.
