Luminous character introduction:

Luminous character is a kind of luminous character which is made by the light source of the light emitting tube. LED  luminous characters with its beautiful day, bright night, energy saving,  durable many advantages have been on the market, with the trend of rapid popularity.

Profit cost:

The profits from luminescence are considerable. If you do not need the word light, do the general word,  only sell the word shell can also. The gloss of the single hand-made word shell is also good-looking and bright than the  acrylic word carved by the machine. Compared with acrylic plastic characters,  the brightness of the same light source is more than double. It will not fade in 5 years,  and it is not afraid of wind and rain for maintenance-free design,  and its life is greatly improved. Compared with neon words,  the power consumption of about 20 watts per square is only about one-tenth of that of neon words. Ten times longer life!

Q&A

LED light characters in the use of 5 common problems and solutions

1, LED short service life:  the theoretical service life of LED produced by regular manufacturers is generally about 80,000 hours. And a lot of light-emitting words do not use enough a year began to frequently replace the LED module,  to customers and advertising manufacturers have brought a lot of trouble and economic losses.

The solution:

Purchase a qualified LED single lamp particle produced by a regular manufacturer (need to have the quality parameter  description provided by the manufacturer),  and make your own module. Do not buy a single LED bulb or a made module cheaply in the electronics market. If you need  to buy a module, you should see how many resistors are installed on the module,  and do not use a module that installs a resistor. The resistance plays a current limiting role in the module and is easy  to heat up. After long continuous use, once the resistor burns out,  the module will not light up. LED lights don't usually break. Do not throw away the module,  just replace a resistor with the same resistance value can be used normally. This can save money for the production  unit. In order to reduce trouble and save money, choose a module with two resistors installed. In addition,  it is necessary to understand the production facilities of the supplier making the module to see if they use anti-static  facilities when making the module. If there is no additional anti-static facilities,  even if the resistance is not burned out in use, the LED lamp is easily damaged by breakdown.

2, the color decay is very fast:  the color of the newly installed luminous word is pure and bright,  and the color can be obviously dimmed in less than a year. Make the font red is not red,  green is not green is very ugly.

The solution:

The safe use current of LED lights is generally 20 mA, more than this value, although the brightness will increase,  but the color attenuation will be significantly accelerated. Therefore, when buying the assembled LED module,  be sure to test its output current value. Brightness below 20 mA is not enough,  more than 22 mA affects the life of the LED, so that the color decay is accelerated.

3, the color is uneven, the color difference is obvious:  mainly manifested in the pure white LED production of larger luminous characters. In the assembly of a single module  performance is not obvious, the entire font assembly is complete, the color difference is obvious,  the entire literal like a map, a white, a blue, a yellow.

The solution:

White LED lights before leaving the factory must go through the spectral separation (not through the spectral separation  of the LED some of the light emitted pure white, some blue, some yellow),  the spectral separation instrument is expensive, the general small factory does not have this kind of equipment,  so the production of white light is generally to the big factory for spectral separation,  because it is not their own factory products,  the spectral separation will not be that N carefully. Some small factories simply do not divide the color. They usually  attract customers at low prices. So in the purchase of white LED do not blindly greedy cheap,  must buy the same manufacturer, the same batch,  the same color LED light tube single particle lamp or module to make the same batch of light word.

4, part of the font stroke, the whole suddenly not bright or when the light is not bright:  the luminous word in use for a period of time after the local or the whole font light source began to blink,  bright when not bright,  until not bright. Most of the light-emitting modules sold on the market are connected using plug wires. In this way,  the advertising manufacturer can install the light module easily and quickly. However,  there are also some new problems,  because the connector is easily oxidized by the moisture in the air during a long time of use,  resulting in poor contact, so that the partial or all circuits are instantly powered off or powered off, resultin
