SMD LED Lights Versus COB LED Lights?

SMD means Surface Mounted Device and COB represent Chip On Board. Light emitting diode or LED for brief has come to be extremely preferred. The Surface Mounted Device (SMD) was first presented in 2008. Whereas, the COB LED technology has been available from 2010 in Guangzhou at the Canton Fair.

These SMD chips are of various shades such as Blue, Green and Red which assists create colorful lights. The COB LED lights are either ceramic or aluminum.

What is an SMD LED Light?
SMD lights use SMT technology which places the LED chip onto a PCB. The PCB board is constructed in a flat item, rectangular-shaped, and is what one said as an SMD. One can see a tiny black spot at the middle of the SMD if you look carefully in an SMD LED, it is the LED chip. The rear side of it has two steel points (cathode as well as anode) which are made use of for soldering with the circuit for the light.

The 5050 SMD has three steel points as there are 3 chips inside. The SMD Led has different kinds, namely 5730, 5630, 5050, 3030, 3014 as well as 2835. Each of these is named according to the dimensions of the LED implying it is based upon the width and also length. Prior to the COB was invented, the SMD 5050 and 3528 was made use of.

What is a COB LED?
The COB LED makes use of the brand-new encapsulation technology. As contrasted to the SMD 5050: 3 chips or the 3528: 1 chip, the COB LED has numerous chips on exact same printing circuit board (PCB). The PCB is on the substrate of the COB. The diode chips of the COB are arrayed in series/ or parallel which relies on the circuit. This substrate can either be ceramic or aluminum. If you are looking for a better thermal conductive efficiency, then the ceramic type is what you require as it will assure a much reduced LED working temperature.

The COB LED has 2 steel link points, the cathode as well as anode. The COB has a much better thermal conductivity as contrasted to the SMD, because of the truth that it places chips directly to the substrate that has a big heat radiation area. In order to have the COB dimension to be as small as possible, the circuit requires to be made to shorten the chip’s distance.

Conclusion
COB LEDs can be found in different shapes which make it less complicated for them to be utilized for different fittings. Whereas, SMD lights can only be made use of for limited fittings, there are many benefits of utilizing COB LED lights such as much better thermal conductivity and lower manufacturing failing rates because of the patent design.

Choosing between SMD and COB LED lights relies on your demands. Both of the lights are being made use of for various applications. When selecting between the two lights, first know about which fixture is being utilized for. LED lights have changed the entire illumination industry.

What is the distinction between solar power street lighting and conventional street lights?

The advancement in photovoltaic technology has changed the means we consider how lights are turned on. It has improved the conversion effectiveness of the solar panels significantly from a mere five percent in the 1940s to 20% lately. The photovoltaic panel market in the Middle East as well as many parts of the world is substantial deal.

Places like Dubai are changing the lighting design of the city and exactly how it is powered. Because of the different advantages of solar street lights, conventional road lights are being replaced. So what are the reasons behind the change? Let’s look at the differences between the two lights.

Different Types of Solar Road Lights
Typically, there are just two kinds of solar energy road lamps, namely grid-tied and off-grid. It is important to recognize the distinction between both types, in order to recognize the difference between solar powered street lights and conventional road lights. The grid connected solar road lamps are attached to an electrical power grid and will certainly be utilizing the electricity from the grid for back-up such as in case there are days when there don’t have enough sunshine.

On the other hand, off-grid solar road lamps aren’t linked to a power network and have their own tiny system. The solar energy is stored in the battery during the daytime and is utilized to power on the street light at night. Typically, they would have the ability to sustain for as much as three days when sufficient sunlight isn’t provided.

As a result, if you live in a location where there are cloudy days, then it would be much better to select a grid-tied solar street lamp.

Mounting and Design of the Solar Powered Street Lamps
If you need the best results for either type of solar powered street lamps, it would be crucial to consider specific engineering specifications such as the panel size, regional climate condition, battery bank, lux brightness, source of light watts, light posts distance, light beam angle and more.

Whereas, when comparing these parameters with traditional street lamps, it can be observed that these parameters are not looked at.

LED Technology
The advancement of LED technology mostly benefits solar road lights as they have actually been manufactured to give far better quality of light or an increased quantity of lumens. They also have a longer life expectancy. This indicates that the maintenance expenses would be substantially less for solar powered street lamps as contrasted to traditional road lamps.

LED lights directly send out which means that the reflecting cup wouldn’t be essential to buy. The traditional road lights just give off diffused light which needs a reflecting cup for far better reflection of light. One can even apply a lens to the LED light.

Moreover, LED lights usually offer you with the same quantity of illumination as filament bulbs but require much less energy. This means that solar powered street lamps call for a reduced amount of electricity to operate.

Environmental Friendly
The primary factor behind individuals changing to solar street lamps is because of the fact that they are environmental protection. For a much higher preliminary investment, the solar road lights have extra advantages that make the investment rewarding.
