first, small size

What's the difference between black crystal and liquid crystal, and LED display? Which is suitable for print advertising?

LED is basically a very small chip, which is encapsulated in epoxy resin.
so it is very small, very light.
second Low power consumption
the power consumption of LED is quite low.
generally speaking, the working voltage of LED is 2-3.6v.
the working current is 0.02-0.03a.
that is to say, its power consumption is no more than 0.1W.
3. Long service life
under appropriate current and voltage.
the service life of LED can reach 100000 hours.
4 Low heat
LED uses cold light-emitting technology.
the calorific value is much lower than that of ordinary lighting lamps.
v. environmental protection
LED is made of non-toxic materials.
unlike fluorescent lamps, Mercury will cause pollution, and LED can also be recycled.
VI Rugged and durable
LED is completely encapsulated in epoxy resin.
it is more robust than light bulb and fluorescent tube.
LED is more robust than light bulb and fluorescent tubeThere is no loose part in the lamp body.
these characteristics make led not easy to be damaged.
LED lamp
high energy saving: energy saving and pollution-free is environmental protection.
DC drive.
ultra low power consumption (single tube 0.03-0.06 w) electro-optic power conversion is close to 100%, The same lighting effect can save more than 80% energy than the traditional light source.

long life: LED light source is called long life lamp.
it means the lamp that never goes out.
solid cold light source.
there is no loose part in the lamp body, and there are no defects such as filament burning, heat deposition, light decay, etc. the service life can reach 60000 to 100000 hours, More than 10 times longer than the life of traditional light source.

changeable: LED light source can use the principle of red, green and blue three primary colors.
under the control of computer technology, three colors have 256 gray levels and can be mixed arbitrarily to produce 256 colors × two hundred and fifty-six × 256=16777216 colors, forming a variety of combinations of different light colors, realizing rich and colorful dynamic change effects and various images.

environmental protection: better environmental protection benefits.
there is no ultraviolet and infrared in the spectrum, neither heat nor radiation, small glare, recyclable waste, no pollution, no mercury, cold light source, safe touch, It is a typical green lighting source.

High Tech Tip: compared with the monotonous luminous effect of traditional light source.
LED light source is a low-voltage microelectronic product, which successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product. It is a "high tech tip" technology of semiconductor optoelectronic devices, with online programming, Unlimited upgrade,Flexible and changeable.
