The word LED, which is the acronym for Light Emitting Diode, is a passive optoelectronic component characterized by its versatility, taking on many forms and being integrated into many optical elements, from screens to light bulbs and even photographic flashes.

One of its best features is its low energy consumption, as well as its longer lifespan, its durability that perfectly withstands almost any type of vibration, in addition to low heat emission.

One hertz is one cycle per second, meaning repeating cycle as an event. For example, hertz is applied physics measuring the number of times for a second wave (either acoustic or electromagnetic) is repeated or can be applied, among other uses, to ocean waves that reach the Beach vibrations per second or a solid. The quantity that measures the frequency hertz is called,in this regard, the inverse of the period. One hertz is an oscillation frequency of suffering a particle over a period of one second.

VDC would be the abbreviation for Volt Direct Current which translated would volts direct current. The idea of ??this type is unidirectional current to the load. Direct current is normally produced by batteries, thermocouples, solar cells and a dynamo electric machine type. The direct current can flow in conductors such as wires, but may also flow through semiconductors, insulators ...

VAC would be the abbreviation of Volt Altern Current which would be translated Volts of alternating current. The difference between VDC is that its sinusoidal oscillation achieving a more efficient energy transmission.

The alternating current is the energy that we receive in our homes, it is generated in the power plants by means of alternators.

The intensity of this type of current varies with time, and changes direction 50 times throughsecond (50hz). The generated voltage changes in the form of sine wave so it is not constant.

The COB Led (chip on board) is a plate (A) with a concentration of LEDs in the form of matrix (B) covered with a special silicone.
This type of led due to its design and installation allow to dissipate in a more efficient way the heat generated by the lighting.
It must be taken into account that the heat is generated in the opposite direction to the light and a low dissipation will cause the led to work in less optimal conditions.thus, its useful life.

Thanks to this design the Led COB is designed to work for long hours.
Its beam of light is multidirectional, so it is a type of diffuse light without dazzling at a point, achieving up to 160 º opening light and have a superior performance to the type of LED SMD.

Its manufacturing cost is 20% lower than an SMD led and its technology offers a reproducible indexchromatic ion (CRI) much higher, getting a better appreciation of colors.

In short, the COB LEDs can produce more lumens using much less energy than the rest of the LED technologies.
