What's happening with LED lighting

I recently attended the International Light Fair in the Philadelphia Convention Center (nice and close for me this year). This is "the" show for every manufacturer throughout the world to showcase their products, and showcase they did. Everywhere I looked were companies presenting LED (light emitting diode) products. It quickly became obvious that this super technology is here and now - poised to be used for every lighting device you can name.
LED's have come a long way since their first development in the 1960's. They were used in various indicator applications, such as automobile dashboard indicators and light switching devices. They differ from traditional light sources in the way they produce light. They are comprised of layers of semi-conducting materials coating a minute chip, which produces light when an electrical current flows through it. The specific color emitted depends on the materials used to make the diode. Light color tones or hues are measured on a Kelvin temperature scale. When a warm tone white light is desired (as we are used to seeing with incandescent lighting), the color temperature is about
2700 K (Kelvin), and is a good choice for most residential use. But if the light needs to be a bit more crisp or halogen-like, a 3000 K bulb would be more preferable.
But, is every lighting device right for LED's? LED's have some unique characteristics. First of all, they emit light hemispherically (straight out), whereas our traditional light sources - incandescent and compact fluorescent (CFL's) - emit light spherically (in all directions). Therefore, LED's are generally more efficient and waste less light. Second, they are impervious to vibration and usually do not need glass enclosures; nor do they get hot, so they won't burn your fingers either. And, traditional light sources burn out sooner when switched on and off frequently, while LED's are unaffected by rapid cycling or dimming features. They also come on at full brightness, unlike CFL's, which have a delay prior to attaining optimal light output and are not reliably dimmable.
They consistently last between 35,000 and 50,000 hours (5 years) if they are left on full time. In comparison, this is ten times longer than a halogen bulb. And if we compared it to a life of 1000 hours for a 75-watt incandescent bulb, or a CFL, which typically lasts 8,000 to 10,000 hours, we see quite a difference in bulb life. However, LED bulb life decreases in higher operating temperatures. LED's do not burn out, they decrease slowly in lighting efficiency. They are already versatile and efficient for small sources, such as under cabinet lighting, stair nosing, pathway and step lights, and where great focus is needed, such as spot lighting. They are not the right choice in all areas yet, such as large open spaces or where the light source is an object such as chandeliers.
LED's are not yet at their peak of lighting efficiency and output. They are advancing quickly however. While LED bulbs are still significantly more costly to purchase and have not perfectly transitioned into all needs, like all new technology, the prices are rapidly dropping with increased research and production. And the real cost when comparing LED bulb life spans to incandescent bulbs is favorable. LED bulbs are also mercury-free, unlike CFL's, making them a greener and safer choice for everyone.

Led lamps to include modern lighting?

Today is understood by modern lighting something else. It is time for a new light sources such as LED lamps can be, to move into residential areas and industrial buildings.

Farewell to the light bulbThe light bulb is adopted gradually from the different versions.Your one must be thankful, because it is an essential element of that progress and modernization enabled. Without artificial light, no modern life would be possible.But the incandescent has had its day, it is no longer contemporary. It produces more heat than light, and requires too much energy.To replace other bulbs, LED bulbs are mainly in the wings to the light bulb.What is LED lighting?With the LED light is absorbed not only a new light, is not only a new lamp in the known version screwed.Led lights are there for some time. They are already successful as Led headlights and LED flashlights used as a vehicle for car and bike lighting, medical and many other areas.With the departure of the bulb, the LED lighting is approaching the main use of lighting, illumination of the living rooms, offices, factories and workshops or street lighting.So far, the small energy-saving LEDs were too weak.Yet united in one lamp or combined with other LED lamps, they have the potential for living room lamp with the characteristics of a modern lamp.What is modern LED lighting?Modern LED lighting is not only the classic Led lamp with the E27 and other versions.These include power rails with LED spots, LED light tubes or Led aluminum strips, LED tealights, like Led recessed floor lights, LED headlight and LED pool lights.Modern LED lighting provides an almost inexhaustible variety of light sources with which we illuminate homes, workplaces and outdoor areas such as garden seats and efficiently.What qualities must a modern lamp today?Modern lamps must be energy efficient. The most important thing is the low energy requirements, as indicated by the LED lamps exemplary.Up to 90% can be saved compared to the incandescent lamps with LED.Then there is the long life of LED lights that help save resources and avoid waste.LED lamps do not require mercury, they may also be designated as an environmentally friendly lamp.Modern lighting means today is not just a clever design. A modern lighting such as LED lamp is characterized mainly by their energy efficiency.

LED Lights MCOB technology COB Technology

As we know, most of COB encapsulation technologies, including the one of Japan, are based on the encapsulation of the aluminum base, which assemble some chips to be encapsulated on the aluminum base. This is what we call the COB technology. The substrate of the aluminum is copper foil, which can only well conduct electric but it can’t process optical processing very well. MCOB technology, quite distinct from the traditional technology, puts the chips in the optical cups according to optics. It aims to make not only one cup, but many cups. It derives from a simple principle, i.e., the light of LED is from the chip itself, which means we need many angles to let out more light. The light efficiency can be improved if we have more light exits. In any cases, the light efficiency of low power’s chips can be at least 15% higher than high power’s chips. The reason is that the chips of high power are bigger and they only have four light exits. However, we can have as many as sixteen small chips on a board and 4*16 light exits. For this reason, MCOB is not only a cup, the purpose of many cups in MCOB is higher lighting efficiency. Just because of many cups, comparing with the ordinary COB tech, products adopting MCOB tech have much higher lighting efficiency.

COB LED Light Technology - Chip on Board LEDs

Chip on Board ( COB ) LED Lighting technology

The greatest power densities on the smallest space are often the basis for unique selling points of various products on the market. These criteria can be realized by the ( Chip on Board ) COB LEDs technology (Chip On Board). Direct contacting of the semiconductors (LEDs) on PCBs allows for optimal thermal management, high packaging density and thus long-lasting and high-performance COB LED modules.

( Chip on Board ) COB LED Light technology

With this technology, the LED chips are in the form of a semiconductor chip, which is neither encased nor connected. The semiconductor chip is described as a "Die". This LED chip is processed by means of a special procedure which is called "Die Bonding". Here the individual chips are placed on the PCB and using the Wire Bonding method, connected to the contact surface of the PCB, which are described as "Pads". Gold wires in the micrometer range are used for contacting. TheCOB LED light technology allows for virtually limitless freedom of scope for the PCBs and thus serves as the basis for totally unique LED solutions.
