What is LED Corn bulb,why should we choose it?

Shenzhen Nuoguan Technology Co.,Ltd. was established in 2010,We are factory in Shenzhen China which have patent to produce LED Corn bulb.

Many customers do not know where to use LED corn bulb and what’s advantage to use it.

1.Why call the light LED corn bulb.

The chips connect the PCB make it’s looks like corn so we call it LED corn bulb.

2.What kind of LED socket does LED corn equipped with?

E40 E39 mogul base E27 Edison base E26 medium base available for ref.

3.How to install or replace traditional lamps?

Install in different direction to reached the lighting effect.

Long life: LED light source that some people call the long life lamps, which means the light never goes out. Solid cold light source, epoxy resin, light body and no loose parts, there is no filament light easy to burn, heat deposition, the light fades and other shortcomings, the service life up to 60000-100000 hours, 10 times longer than conventional light sources above.

Many changes: LED light source with red, green, blue trichromatic principle, under the control of computer technology to make three colors with 256 gray levels, and any mix, you can generate 256 × 256 × 256 = 16777216 colors to form a different light color combination of varied to achieve a variety of dynamic effects and variety of images, you can choose a variety of colors instead of ordinary incandescent light bulbs, higher brightness.

The environmental protection: environmental benefits of better, no ultraviolet and infrared spectra, neither heat nor radiation, glare small and recyclable waste, no pollution, no mercury elements, cold light source, safe touch, typical of the greenlighting.

High-tech tip: compared to the monotonous glow of traditional light sources, LED light source is low voltage microelectronic products, the successful integration of computer technology, network communication technology, image processing technology, embedded control technology, so it is also digital information products, semiconductor optoelectronic devices, “high point” technology, with online programming, unlimited upgrades, flexible features.

Disadvantages: led lamps Despite its many advantages, but in a very passive situation of any course, restricted its extensive high prices, making it difficult to into ordinary people’s homes, followed by heat lamps is currently a majorproblem, so let popularity led lamps reduce costs and solve the heat lamps is more critical.

Inadequate

The management of the reduced junction temperature of LEDs is a critical issue because it will affect many physical parameters such as light output, wave length and LED’s lifetime. The model used in this simulation consists of a metal core PCB attached with six chips(GaN on sapphire, Ag paste, cathode/anode, silicone encapsulant, mold frame) for 5W LED module. The MCPCB is composed of an aluminum base plate, a thin layer of dielectric, and a layer of copper. The temperature distribution of the developed LED module was simulated, and the thermal behavior within this 3-D model was investigated by using a commercial computational fluid dynamic code (Fluent 6.3). The results showed that the temperature variation along the vertical direction is more dominant than that in the circumferential direction due to the heat spreading effect of the copper layer. The ratio of heat dissipation through the each thermal path was calculated and compared for various input conditions. Several parameters that increase the junction temperature, such as the thermal conductivity and thickness of the dielectric layer and the encapsulate material, heat transfer coefficient and input power were also examined. Finally, a combination of designs for attenuating the junction temperature was proposed.

Description:
LED Fluorescent Bulbs, Clean, safe, higher efficiency, long-lasting LED lighting for easy, direct drop-in standard T5/T8/T10/T12 fluorescent tube replacement. LED Fluorescent Lights are the next generation solution to replace conventional fluorescent light. They feature higher efficiency, more reliability compared to the previous generation. They are well-suited for use anywhere, homes, offices, museums, galleries, shop windows, hotels, restaurants, meeting rooms, just like conventional fluorescent lights. With patented thermal control technology, and special designed aluminum housing, LED substantially achieves good thermal property and plays more stable performance and of course will last up to 50, 000 hours compared to 5, 000 hours from conventional fluorescent lights. LED adopts high efficient SMD LEDs, which makes them produce equivalent light intensity of 40 watts fluorescent lights at only 18 watts consumption (1.2m, 60LEDs). They can directly drop into existing T8 sockets, no need of ballast and starter. LED is patent pending product; While the original chip and phosphor coating adopted for LEDs are both patented.

"The government says that if every American home replaced one light bulb with a compact fluorescent light bulb, we could save enough energy to prevent greenhouse gases equal to the emissions of more than 800, 000 cars. Certainly great news, yet recycling burned-out CFL light bulbs poses a quandary for homeowners. " -The Dallas Morning News, April 17, 2008.

Upgrading your failure prone, environmentally hazardous fluorescent lighting system to solid state, LED technology is now as easy as replacing the bulb!

In Kim is a graduate student at the Chonbuk National University, Korea. He also works at a professional engineering company that is consulting for the CAE industry in the field of the CFD, especially in a chemical engineering and plant group. His research interests include the modeling and analysis for the thermal processing system.

Byng Joon Baek received his B.S. in Mechanical Engineering from Seoul National University, Korea, in 1979. He then received his M.S. and Ph.D. from Seoul National University, Korea, in 1981 and University of Missouri-rolla, USA in 1990, respectively. Dr. Baek is currently at the Division of Mechanical Engineering System, Chonbuk National University, Korea. His research interests include the modeling and analysis for the thermal/mass transfer for the efficient thermal processing system.

LED energy efficient environmentally friendly for people well-known, but the LED itself or there are some problems, LED lamp Corn Light is no exception.

Industry for heat from both sides of the the thermal conductivity (HeatConductivity) and cooling (Heatdissipation) has always been discussed. For the industry too much emphasis on the LED heat dissipation in the front-end approach to additional heat-conductive layer, the crown Chemicals Corp. vice president of research and development, Dr. Ye Shengwei, the fundamental solution is quite different from the general practice of the industry. Dr. Yip, import the following formula Thermal Resistance Rtotal is = Rl – s + Rs + Rs-a, the entire LED total thermal resistance of LED to the thermal resistance between the substrate Substrate (RL-s), for signing the substrate thermal resistance ( Rs) coupled to the substrate to the air side of the thermal resistance (Rs-a) the sum of the three.

MCPCB heat industry’s usual aluminum substrate, the bottom of the aluminum block and the upper copper foil group, in the middle fill thermal plastic (Adhesive). How to better solve the heat problem, this is a problem worthy of study.

To better solve the problem of heat dissipation, the development of corn lamp aluminum lamp body. Using aluminum lamp body, together with the aluminum plate. Can solve the heat problem, thereby increasing lamp life.

4.How many height suitable to install LED corn bulb?

Different Wattage install different distance.

5.How to distinguish bad and good quality LED corn bulb?
1)Material uses.
2)Whether have a good design for heat dissipation to enlarge lifespan.\

Nuoguan Corn bulb quality :

1)Meanwell power supply for high voltage,Rubycon capacitors for 20~120W Corn bulb.
2)Aluminum heatsink inside good for heat dissipation.
3)Whole in lamps base also good foe heat dissipation.
