Utilization of thermally conductive composites

Technology

LED indoor lighting fixtures using thermally conductive composite materials

The primary purpose of public lighting is to illuminate objects or spaces that would otherwise be indistinct and dark at night.

Patent No. 10-1447248

By adding graphite or aluminum powder or silicon carbide powder with excellent thermal conductivity to the epoxy resin and compounding it, an epoxy composite material with excellent thermal conductivity is manufactured and applied to the interface between the LED PCB and the heat sink to greatly improve the heat dissipation performance of LED luminaires.

The temperature of the LED element can be kept relatively low
Advantages in LED element deterioration, lifespan, and optical properties
Polymer composite grease (1~2W/mK) with heat conduction efficiency that is about twice higher than
that of conventional grease products (~1W/mK)

The heat generation of LED lighting is divided into two-stage mechanism of heat conduction, which transfers the heat generated from the LED element to the heat sink, and the heat radiation mechanism, which conducts the heat accumulated in the heat sink to the atmosphere.

Step 1 : Heat generated from the LED element is transferred to the heat sink, and heat transfer material is inserted.

Step 2 : Maximize the specific surface area or install a forced convection system where the heat accumulated in the heat sink is radiated to the atmosphere

Heat dissipation improvement technology for LED lighting devices using polymer composite materials
(composite material manufacturing technology)

Minimize air gap between LED module and heatsink
Improved vertical/horizontal thermal conductivity by using complex
inorganic fillers
Applicable without limitation to the shape of the LED Module
LED device thermal stress reduction technology
It is possible to improve the heat dissipation characteristics without
changing the design of the LED luminaire.

Thermal Conductivity of Composite Materials (Epoxy/Expanded Graphite)

Thermal conductivity can be improved by developing the optimal composition
ratio of graphite and inorganic composite thermal conductive filler.

This technology is a world-class advanced technology that has a higher
thermal emissivity by more than 20% compared to similar technologies
