In general, LED lighting is said to have a long life, but in fact, the life of catalog values could not be guaranteed. This is because the problem of heat generated from the LED chip causes various problems such as a decrease in the life of the chip itself, deterioration of the resin due to heat, and a failure from a crack due to the heat cycle.
We solved these thermal problems with the new heat dissipation material “ACM-a” and “Heat Bridge Structure”.
These two new technologies have made it possible to quickly transfer the heat of the LED to the heat sink, ensuring the LED's inherent long life.
Kandenko adopted this new technology for LED lighting equipment for high ceilings, and received the Encouragement Prize from the “JFCA FAIR 2015” sponsored by the Nippon Electric Construction Industry Association.
This material has also been adopted in factories with severe conditions, such as factories that have melting furnaces and high temperatures near the ceiling, and factories with constant vibration caused by presses.

●Featured Properties

• Excellent thermal conductivity and diffusivity
  → Excellent exhaust heat and long life of LED chip
• Thermal expansion coefficient equal to LED chip
  → No trouble due to solder cracks

●Description

・From the W results, an extremely heat-resistant LED substrate was realized.
#1 1. ACM-a, a new material with excellent heat dissipation was adopted.
#2 2. Adopted a new technology heat bridge structure.
・From a careful CFD simulation, an aluminum chassis and an aluminum radiation fin with a structure that has excellent exhaust heat was realized.
・Improved the luminous efficiency by devising the arrangement of the LED chip, achieving an equipment efficiency of 110 (lm / W) or more and a weight of 4.0 (kg).
・Achieved the same floor illumination with 1/4 the power of a 400 W mercury lamp.

This LED lighting is for high ceilings, which adopted the new heat dissipation material ACM-a developed by our company for LED modules. ACM-a has solved the "thermal problem" which is a major obstacle for the spread of LED lighting.

●Technology:Composite

Solar Powered White LED Street Light is an outdoor lighting system that realizes the elimination of the need for dead bulb replacement work or an external power supply, by combining solar panels, storage batteries and white LED lighting.
It turns on automatically after sunset and turns off automatically after a set time.
For normal use, it lights up at an energy saving luminance, and brightens at a rated luminance for about 15 seconds when a body is detected by the detection sensor.

A feature of ACM-i manufactured by our company as a material to replace graphite jigs is that it is easier to handle than graphite.
Features such as less dust generation, possible to plate, and a higher strength than graphite, significantly eliminate graphite handling defects.
In addition, there is the benefit that being light weight, dimensional error does not occur even if heat is applied because the thermal expansion coefficient is lower than SUS etc.

●Featured Properties

• Low coefficient of thermal expansion, less likely to cause dimensional errors
• Less dust generation than alternative graphite alone
• Ni-P plating is possible, which is difficult for graphite

●Description

ACM-a has better thermal conductivity than graphite and higher emissivity than metals such as aluminum, so it has a high ability to release heat from the fins into the air, making it an ideal heat sink structure.
It is also has a low coefficient of thermal expansion and is less likely to cause dimensional errors, so dust generation is minimal, making the material extremely easy to process.

●Description

The materials used in robot hands and XY tables in the past were mainly iron alloys and aluminum alloys, and in particular those that require high Young's modulus included alumina sintered products.
Iron alloys have a relatively high Young's modulus, but they have a large specific gravity, so the inertia force works to move at a high speed, which places a burden on the position accuracy and the motor.
Aluminum alloy is lightweight, but its Young's modulus is small, and vibration occurs at high-speed movement, resulting in poor position accuracy.
Therefore, sintered alumina products have come to be widely used because of their high Young's modulus and relatively low specific gravity.
However, sintered alumina products are extremely difficult-to-process materials, require high mechanical costs, and are extremely delicate materials that are easily broken.

In order to solve the above problems, we have developed a composite of Al + 9Al 2 O 52 B 2 O 3 and an aluminum alloy (A Al + 9 Al 2 O 52 B 2 O 3).
A Al + 9Al2O52B2O3 is an excellent alternative to existing materials because it has a high Young's modulus, a low specific gravity, and is easy to process.

●Featured Properties

• Lightweight compared to cast iron / High Young's modulus
• Excellent machinability
