LED luminous word is to the LED exposed light (9mm exposed light) as a source of light advertising logo products, LED luminous word with its diverse colors, uniform bright luminous effect, efficient energy saving, easy to install and use by the majority of advertisers love, and quickly popularize. Sometimes LED words with a long time will appear color deviation, sometimes there will be a problem of brightness is not the same, the following shenzhen blue king optoelectronics co., LTD. Tell you what is the cause of these problems?
I. different models of LED exposed lights:
Different manufacturers of different models of lights, the use of luminous effect is different. So when in production of led lamp are all requires the use of unified batch of led lights to avoid this problem, sometimes the same factory also can produce certain difference of different batches, so choose the led manufacturer must choose the right brand, to avoid this very low-level mistakes, which yao when choosing led visible light (9 mm exposed lamp, for example) and understand which issues must be pay attention to? 1. Try to choose products with consistent LED exposed light source voltage, consistent color temperature band and consistent package batch number.
Ii. LED light leakage:
There are some leakage of electricity in some installed field lines or LED exposed light emitting word products, or the lines are not properly connected when making luminous words, or the joints are not welded properly. Thus require employees at the time of LED words make the line must be welded and the line check is good, the most important thing is make sure the power supply of electric parts and LED visible light into electricity to keep good contact, not loose, but also to do a good job of waterproof, don't let the connection part of LED light-emitting character have get wet in the rain.
Iii. Uneven arrangement of 9mm exposed light sources of LED words:
Make sure before production LED word spacing between good light and light, good luminous word power, matching the good foot drive power supply, sometimes with luminous word LED visible light lamp number is too much, while the power is not enough, can appear stroboscopic, brightness is not enough, the phenomenon such as color is not consistent, the arrangement of light density according to the requirements to operate, advertising company in the LED lamp production are specifications, different LED word production according to customer requirements to unified arrangement LED visible light source.
Iv. The transformer power of led words is too small:
To match the transformer according to the number of LED exposed lights used for each word, the main line of LED outdoor lighting must use high-quality national standard copper core line. 9 mm exposed exposed lamp lights and 12 mm power of all sorts of color lights are as follows: 9 mm visible light and visible light white light 0.12 W / 12 mm, 9 mm appear visible light yellow lights and 12 mm: 0.12 W/star, 9 mm exposed exposed lamp lights and 12 mm blu-ray: 0.12 W/star, 9 mm exposed exposed lamp red lights and 12 mm: 0.22 W/star, 9 mm exposed exposed lamp lights and 12 mm green: 0.22 W/star, 9 mm exposed exposed lamp lights and 12 mm pink light: 0.26w/piece, 9mm exposed light and 12mm exposed light orange light (exclusive for Vienna hotel) 0.26w/piece, 12mm full color exposed light: 0.3w/piece.
