Mini USB lamp)
, mini USB lamp is portable and convenient.
Mini USB lamp developed, of course, has its own advantages and disadvantages, the following her alone to explain for everybody!
Mini USB lamp advantages: 1, mini USB lamp light source directivity, on-demand lighting, as an emergency lamp is better;
2, mini USB lamp is small in size, the LED is basically a small chip is encapsulated in epoxy resin, and so it is very small, very light;
3, mini USB lamp illumination is enough, meet the demand of your general illumination;
4, mini USB LED lamp power consumption is low power consumption is quite low, the working voltage of the LED is generally 2 -
Working current zero.
It means that the electrical energy it consumes less than 0.
5, mini USB lamp of green environmental protection, high efficiency and energy saving, the LED is made from non-toxic material, unlike fluorescent mercury can cause pollution, LED can also be recycled at the same time;
6, mini USB lamp without uv and infrared light.
Strong and durable, the LED is fully encapsulated in epoxy resin, and it is strong than light bulbs and fluorescent tube.
No loose parts in the body, these characteristics make LED is not easy to damage;
7, mini USB lamp energy saving energy without pollution is environmental protection.
Dc drive, low power consumption,
Single pipe 0.
Electric power conversion is close to 100%, the same lighting effect than the traditional light source, energy saving more than 80%;
8, mini USB lamp long life: LED light source has called it longevity light, meaning never extinguished the lights.
Mini USB lamp faults: 1, the price is expensive, require constant current drive, bad heat treatment easy droop;
But you get what you pay for)
2, lighting intensity is small, not suitable for large area lighting;
3, millet usb lamp will also fever, need to heat;
4, infancy, landscape lighting, LED lighting is mainly applied in large environment, with eyes, is not suitable for high current is given priority to with test;
5, led lights will also be fever, need to heat dissipation.
Leds shall simply use light source;
It used to drive power supply, optical and thermal conductivity;
Small 6 LED lamp bead, loss of a few years later will slowly to change, easy to cause the whole lamp scrap.
