Application of New Materials in LED Lights

In the LED field, cost and heat dissipation have always been two major problems that plague the development and popularization of LEDs. Discovering new raw materials to improve light efficiency and reduce costs has always been the direction of LED technology development. 

1. Plastic aluminum

After combining the advantages and disadvantages of plastic and aluminum heat dissipation, the LED-coated aluminum heat dissipation kit was developed and put on the market. This kind of heat dissipation material is wrapped with the outer plastic material, and the inner part is made of an aluminum heat-conducting material. The product has good performance, strong thermal conductivity, and controllable cost. In addition, the plastic itself is easier to process and shape, so the shape and style of the coated aluminum are rich, which meets the needs of different places.

Compared with aluminum, plastic aluminum heat dissipation has the advantages of high quality and low price, which reduces costs, meets market demand, meets the production needs of merchants, and increases profits. In addition, this material is easier to shape and build, so it can be recycled, cost savings, and environmental protection.

2. Magnesium alloy

The main element is aluminum, which is then mixed with a small amount of magnesium or other metal materials to increase its hardness. It has the characteristics of high thermal conductivity, high strength, low density, corrosion resistance, recyclability, good thermal conductivity, and resistance to electromagnetic radiation. The shell and heat dissipation module of the LED lamp is made of magnesium-aluminum alloy, which can quickly dissipate the heat generated by the LED lamp when it is working, and extend the service life of the lamp. The advantages of magnesium alloy used in LED lights are as follows:

(1) Good heat dissipation

Magnesium-aluminum alloy can effectively dissipate internal heat to the outside. Magnesium-aluminum alloy is used on the housing and heat dissipation components to make the electrical housing without heat dissipation holes.

(2) Lightweight

In order to achieve the purpose of environmental protection, energy-saving, and emission reduction, the lighting accessories made of magnesium-aluminum alloy profiles can not only effectively reduce the load-bearing and load, but also minimize additional damage.

(3) Better electromagnetic shielding performance

Applying it to LED lamps can effectively reduce the harm of electromagnetics to the human body and reduce the influence of electromagnetics on communication signals.

3.Graphene

Graphene is gradually replacing metal parts for thermally conductive parts of LED lamps, including lamp holders, heat sinks, and housings. Compared with metal materials, graphene has the characteristics of uniform heat dissipation, lightweight, and flexible design. Application to LED lamps can reduce system costs by 30%.

4. Two-dimensional semiconductor MX2 material

With unique lattice structure and characteristics, M is usually a transition metal element, and X is usually a chalcogen element. Quantitative transient absorption measurement shows that the charge transfer time of the heterojunction structure of MX2 material is less than 50 femtoseconds, which is equivalent to the fastest recording time of organic optoelectronic devices.
