LED is called the fourth-generation illumination source and it’s green light source. It has the characteristics of energy saving, environmental protection, long life and small size. It can be widely used in various fields such as indication, display, decoration, backlight, general illumination and urban night scene. Some economically developed countries in the world have launched a fierce technical competition around the development of LEDs. The United States has invested $500 million since 2000 to implement the National Semiconductor Lighting Program. The European Union also announced the launch of a similar “Rainbow Program” in July 2000.

Under the support of the “863” program, the Ministry of Science and Technology of China first proposed the development of semiconductor lighting plans in June 2003. Over the years, LED lighting has been valued by the state and various levels of government for its energy saving and environmental protection advantages. Various localities have introduced relevant policies and measures to accelerate the development of LED lamps; mass consumers are also eager for this new environmentally friendly lighting products. However, due to the high cost of technology and promotion, the LED lighting products that make thousands of consumers look forward to it have been unattainable, and have not been able to unveil their mysterious aristocratic veil!

With our company’s technology development and production costs decrease, the situation of LED lighting is changed. MIC LED lighting products with good quality and low price will bring revolutionary impact to the world lighting industry and bring bright gospel to the consumers!

High energy saving: MIC LED corn light is environmentally friendly without pollution. It can save more than 80% energy than traditional light sources.

Long life: Some people call it a long-life lamp, which means a lamp that never goes out. The service life can reach 50,000 to 100,000 hours, which is 10 times longer than the traditional light source.

Multi-variable: LED light source uses the principle of red, green and blue. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, which can produce 256×256×256=16777216 colors to form different light colors. The combination of changes, colorful and dynamic effects and a variety of images, you can also choose a variety of colors instead of ordinary tungsten light bulbs, higher brightness.

Environmental protection: better environmental protection, no ultraviolet and infrared rays in the spectrum, no heat, no radiation, small glare, and waste can be recycled, no pollution, no mercury, cold light source, safe touch, typical green Lighting source.

High-tech tip: Compared with the monotonous lighting effect of traditional light sources, LED light source is a low-voltage microelectronic product, which successfully combines computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product. Semiconductor optoelectronic device “high-tech” technology, with online programming, unlimited upgrades, flexible and changeable features.


LEDs are well known for their energy efficiency and environmental protection, but LEDs still have some problems, and LED light corn lamps are no exception.

People discuss heat dissipation from both heat conduction (Heat Conductivity) and heat dissipation (Heat dissipation). The MCPCB heat-dissipating aluminum substrate that is commonly used in the industry consists of a bottom aluminum block and an upper copper foil group, and an intermediate heat-filled adhesive (Adhesive). How to better solve the heat problem is still a problem worth studying.

In order to better solve the problem of heat dissipation, MIC LED corn lamp with an all-aluminum lamp body was developed. The aluminum body is used as a lamp body, and an aluminum substrate is added, together with a fan to dissipate heat. It can solve the heat dissipation problem well and increase the life of the lamp.

How to choose LED corn light?

The light source

LED light source (also known as LED lamp bead) has domestic lamp beads and imported lamp beads (including US chips, Japanese chips, German chips, etc.), but China’s lamp beads are the best value-cost rate. When asking the manufacturer what kind of lamp bead to use, it must be made clear, because the lamp bead is different, the price difference is very large. The price of imported LED lamp beads is relatively expensive. It is generally used by customers in the production. If the customer does not require it, the lamp bead in Taiwan is generally used. The price is good. However, there are manufacturers of bad companies who use garbage balls to defraud customers for profit.

At present, many small packaging factories in China do not have color classifier, which leads to different color of the lamp bead. So it is difficult to guarantee the quality

Workmanship process of LED corn light

Under normal circumstances, it is fully automatic machine processing, exquisite workmanship, good-looking appearance. If the work is not good, it is artificially, which proves that the company is not strong.

Housing material of LED corn light

Generally, the corn lamp will use aluminum lamp body and plastic lamp holder. Aluminum not only looks beautiful and smooth, has no roughness, and has good heat dissipation performance.

Brightness of LED corn bulb

Different brightness, different price. Therefore, customers must know clearly what kind of brightness they need,which help them accurately locate their products, then manufacturers can give you accurate prices.

Finally, the customer is reminded not to blindly pursue low-cost LED lamps. The low-quality LED lamps are not as long as the traditional lamps and not bright enough, so they lose the high brightness and long life of the LED lamps.

How far is LED lighting from us?

Energy and the environment are major challenge for humans in the 21st century, so green energy conservation has become the focus of the world. Taking lighting as an example, its power consumption accounts for about 20% of the total, which greatly reduces lighting power consumption as an important way to save energy. With its energy-efficient features, LEDs have achieved unprecedented opportunities in the field of lighting.

LED light-emitting diodes, also known as light-emitting diodes (LEDs), are semiconductor light-emitting devices that convert electrical energy into light energy and are solid-state light sources. It uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, carriers in the semiconductor recombine, releasing excess energy and causing photon emission to generate visible light. Compared with conventional vacuum incandescent bulbs, semiconductor LED light sources have unparalleled advantages. The working life of semiconductor LED is extremely long, more than 10 times that of traditional lighting equipment, which effectively reduces the cost; it has low power consumption, high luminous efficiency and energy saving, and is a suitable candidate for future energy strategy; LED light source is small in size and weight Light and adaptable, it provides great flexibility for design and application; since white light high-power LED light source is a solid bulb, it does not need to be packaged in vacuum glass, so it is resistant to impact and collision; LED light source is still a pollution-free Mercury source.

Especially with the improvement of LED chip technology, the reduction of price and the maturity of related drive circuits, the application of LED light source in the field of illumination becomes possible. Under the circumstance of global energy shortage, some developed countries and regions in the world have implemented plans to promote the development of the LED industry. The United States, Japan and other countries and Taiwan have predicted the LED lighting efficiency. 55% of the US incandescent lamps and fluorescent lamps have been replaced by LEDs, which can save 35 billion US dollars in electricity bills annually and reduce 725 million tons of carbon dioxide emissions per year. The replacement of 100% of incandescent lamps in Japan into LEDs can reduce the power generation of 1 or 2 nuclear power stations and save more than 1 billion liters of crude oil per year. In Taiwan, 25% of incandescent lamps and 100% fluorescent lamps are replaced by LEDs, saving 11 billion kWh per year.

In the context of global energy shortages and increasing environmental protection requirements, LED lighting technology has significant advantages such as high brightness, long service life, energy saving, and environmental protection. With the rapid development of LED technology, LEDs have become the common lighting source. The closer it comes, it will become a new lighting revolution in the history of human lighting following incandescent and fluorescent lamps.
