Art: Giant Luminous Fish Made Of Discarded Plastic Bottles

Rio de Janeiro, Brazil, responsible for hosting this year's United Nations Conference on Sustainable Development (also known as "Rio +20"), they are specifically designed to Botafogo beach in the conference produced by the hundreds of discarded plastic bottles made ​​of three giant LED luminous fish .


There are websites statistics debris drifting in the sea there is 60-80% of plastic artists through the statue to remind people of the importance of recycling plastic bottles and discard plastic bottles (especially in the sea) would pose a risk to animal life, and to encourage people to rethink how to recycle resources to protect our environment.

The Advantages of LED Light In Energy Transformation

At present, more and more LED lamps have replaced traditional lighting, and use in display, advertising lighting, underwater lighting, architectural lighting, street lamps and other applications. The following are several commonly used lamps.

From the above table we can easily know that LED lamps are 1/10 power consume of incandescent lamp. Compare with fluorescent tubes, energy saving is also more than 50%, and completely avoid the mercury. LED lights are not only avoid increasingly serious energy crisis, but also for the purification of the ecological environment provides an important way. Therefore, the potential of LED energy saving lighting is enormous.

Nine Advantages of LED Strip

1. Pure colors: LED flexible strip or LED bulb adopt high brightness SMD LED as light-emitting element, hence, have the advantages of LED light-emitting element which is pure light color, soft, no glare. Either as decorative purposes, and can cater to lighting purposes.

2. Flexibility: LED strip light with very soft FPC as the substrate, can be bent without breaking, easy to shape, suitable for a variety of advertising and styling.

3. Small heat: LED Flexible Strip light-emitting element is a LED, the single LED power is low, typically 0.04 ~ 0.08W, so heat is not high, can be used as decorative lighting for aquarium without generating a lot of heat caused by rising water temperatures, affecting fish growth.

Five LED Driver Chip Debugging Techniques

1.      High temperature of chip
This is mainly for high-voltage of the built-in power modulator driver IC. If the current consumption of the IC is 2mA, 300V voltage is applied above the chip, the chip's power consumption is 0.6 W. It will certainly cause the high temperature above the chip. The maximum current of the driver chip is from drive power consumption of the MOS tube. So think about better heat sink.

2.      Power tube high temperature
Power consumption of the power tube is divided into two parts which are switching loss and conduction loss. Note that most of the occasion especially LED electric drive applications, switching damage is much larger than the conduction loss. So try to reduce the frequency, however, you need to know that when the frequency is reduced, in order to obtain the same load capacity, the peak current is bound to large or inductance becomes large, which are likely to cause the inductor into saturation region. If the inductor saturation current is large enough, you can consider the CCM (continuous current mode) to change into DCM (discontinuous current mode), so you need to add a load capacitance.
