Light Emitting Diodes

(LED) is a semiconductor diode that emits incoherent narrow spectrum light when electrically biased in the forward direction of the p-n junction . This effect is a form of electroluminescence. Maki Solar’s lighting products use an array of high brightness Light Emitting Diodes (LED), as opposed to the traditional incandescent bulbs or fluorescent lamps to create light. Below we offer a brief discussion of the LED technology and the advantages and techno of our products.

1. Better efficiency light-emitting diode

Maki Solar has designed the Special increased efficiency lens to increase the efficiency. To design a more uniform and collimateding LED light, we use a geometrical relation to solve the optical path of ray tracing path. Then we trace and analyze the rays emitteding from the LED chip.

As illustrated above, the direction of the LED light passing through the lens is adjusted by a refractive lens. The use of this technology in our products is the reason why our warning light products perform better than competing articles.

2. Economy

Why Maki solar’s products use the LED to instead of traditional incandescent bulbs? Despite their initial high price, the use of LED lighting can offer significant cost savings over time, not only in terms of reduced energy consumption, but maintenance as well. Even in hostile conditions, the typical working life of an LED can be several tens of thousands of hours; most domestic bulb filaments expire after just a couple thousand hours; even compact fluorescent lamps come nowhere near the working life of LEDs. Finally LEDs do not suddenly burn out - they slowly fade over time, giving ample opportunity to plan for replacements (an event which will be rare –after several years, possibly even decades, of normal use). Even at the end of its working life, an LED will still give some light.

3. Colorful

The color of the light produced by an LED is dependent on the combination of crystal materials that comprise the silicon chip. Therefore, LEDs produce only one color needed for a particular application. Almost all the energy drawn by the LED is used to produce the intended color without the need for filters. Currently, LEDs are available in white, amber, red, green and blue output colors.

Solar Panels

Solar panel technology, also called "photovoltaic" technology or PV for short, is a solar power technology that uses solar cells or solar photovoltaic arrays to convert light from the sun directly into electricity. There are many different types of solar panels, such as single crystalline silicon, poly crystal and amorphous types. In the majority of Maki Solar products we use crystalline silicon solar panels because their transformation efficiency is relatively better than that of other kinds of solar panel. In this way we can also guarantee that all of our manufactured products have the optimum charging efficiency.

Strict Control of Solar Panel Sources

It is the case that the quality of most solar panels on the market has been uneven with great variation in their charging efficiency and price. It is for this reason that Maki Solar chooses solar panels only from reputable manufacturers who specialize in producing stable quality products that have gone through ISO9001 international certification. All our solar　panels have gone through the relevant authentification process. In addition they are all cut from larger panels that is to say that scraps or fragments are never used. We insist on these criteria so as to give our clients products first-rate efficiency products.

Zero Problem Quality Control

After the supplier of the materials has been selected further steps are taken to ensure that the finished products will have no problems. All Maki Solar stock material and every solar panel undergo another testing process (see the picture below). If we find any discrepancy from the original factory specifications the deficient item is immediately returned to the manufacturer. In this way we can ensure that all the solar panels in our products all conform to product specifications. Moreover after installation the solar panels undergo another testing process designed to guarantee that there has been no mistake at the time of installation that would result in the product being unable to operate. Therefore Maki Solar produced products have all undergone multiple inspections. The product efficiency is such that can always set one's mind at rest.

Solar Panel Testing Process

In our unceasing promotion of product efficiency not only does Maki Solar take great pains to choose the best solar panel source and then subject them to a rigorous quality control screening process, we have take further steps to enhance product efficiency. This is being done by trying to make advances in the technology. We are currently working in conjunction with the NCU (National Central University) photonics centre, one of the best photoelectronic research centers in Asia to take the research a step further. For example, very recently one research program directed at studying Solar Concentrators was recognized by the national SBIR program (United News). It was found that with the Solar Concentrator we not only can reduce the surface area of the solar panel but also cut the net cost and increase the transformation efficiency. At present, although there is still some limitation in the use of crystalline silicon solar panel technology, we at Maki Solar believe that in cooperation with the NCU Photonics Centre and in collaboration with the national agency, before long we should be able to solve this problem. Moreover the Solar Concentrator used together with the Ⅲ-Ⅴ compound solar panel can surmount any other thresholds. Solar energy productivity can be increases 2 to 3 times which means that using Maki solar products leads to faster charging and greater product usefulness.

Power Storage

Power Storage is a very important factor in solar powered illumination products. During the day-time the solar panel transforms the energy of the sun to electrical energy which in turn must be stored up for night-time use, at which point the energy storage device furnishes the energy needed for illumination. The effectiveness of the product depends on the effectiveness and usage life of the power storage device. This is the reason that Maki Solar is so absorbed in power storage research, and how to incorporate the latest research into our products. In addition we seek to promote product quality, to insure that all our products are of the incomparable quality.

Brief Battery Introduction

There are many different types of storage devices or batteries being used in solar products. At the present time the most commonly used types in the industry are the Ni-Cd (Nickel Cadmium), Ni-MH (Nickel Metal Hydride), and lithium batteries. Maki solar has taken great pains to test a variety of different options to really select the most appropriate storage device, in order to ensure that our products have the optimum efficiency and performance.

Battery Quality Control

Maki solar only selects batteries manufactured by ISO9001:2000 certified manufactured producers. Moreover prior to installation, we make sure that each and every battery passes our testing process (see picture below). If there is any problem with the battery of they do not meet the specified standards they are classified as substandard and sent back to the producer. In this way we can guarantee our product’s quality and safety for use. After installation of the batteries the effectiveness of the final product is again tested before it is shipped out. This meticulous monitoring process is what allows us to offer increased product quality and stability, and to build up customer trust in their reliability.

Maki Solar Power Storage Technologies

At present, the technology for lithium, nickel cadmium and nickel metal hydride batteries has already been well-developed, and they are in common use in many products as reliable energy storage devices. Problems connected with their design and net cost have been resolved. However our design engineers have focused on finding solutions to problems encountered in the use of lead batteries. The limitations of traditional batteries are ultimately related to the chemical reaction that occurs therein. Maki solar has made a breakthrough in this area. We have improved the technology to find ways to overcome usage life and temperature limitations as well as large electrical current requirements which also have a direct influence on usage life. Two years ago we started to study ultracapacitor technology and since then have begun to integrate this technology more and more into our products. Up to the present time these ultracapacitor products have already entered the market place in to most countries. Product quality has be stabilized and battery usage problems have successfully been overcome. Our ultracapcitor products have a usage life of 5-7 years, an increase 2-3 times that of the 2-3 year lifetime of traditional batteries. Not only has the battery life increased but this also saves on the manpower and cost needed to change the batteries.

The ultracapacitor advantages:

• Energy efficiency
• Environment-friendly (Low toxicity of materials used.)
• Virtually maintenance-free
• Operates reliably in harsh environments
• Working temperature (-20ºC to 60ºC)
• Wider storage temperature (-25ºC to 80ºC)
• Little degradation over hundreds of thousands of cycles.
• Long life－10000~1000000 recharging cycles, 7~10 years

Ultracapacitor

The Ultracapacitor is a futuristic rechargeable energy storage device.The charge is stored electro statically (i.e., physically) in polarized layers between an ionically conducting electrolyte and a conducting electrode. Moreover, the ultracapacitor ‘s physical properties allow it to store energy much faster, i.e., with more power, than a battery which must rely on time-consuming chemical reactions. Also, these physical properties mean vastly superior tolerance to repeated charging and discharging. Compared to traditional batteries, the ultracapacitor has one tenth the energy density of the former, but more than a thousand times longer cycle life.
