Our commonly used LED diffuse reflection light strip is mainly composed of three parts, 1. Using high thermal conductivity aviation aluminum substrate, the main component of LED diffuse reflection light strip acts as a bracket. 2. Use high-power 2835 lamp beads as the light source. 3. Add special PMMA optical lens. The combination of these three can produce a new type of backlight product with ultra-high brightness and larger emitting angle. This article mainly discusses the characteristics of high thermal conductivity aviation aluminum substrates.

LED diffuse reflection light bar aluminum substrate is a low-alloyed Al-Mg-Si series high-plastic alloy plate, which has good thermal conductivity, electrical insulation performance and mechanical processing performance. 4 Compared with the same thickness and the same line width, the aluminum substrate of the LED diffuse reflection light bar can carry a higher current, the withstand voltage of the aluminum substrate of the LED diffuse reflection light bar can reach 4500V, and the thermal conductivity is greater than 2.0. The characteristics of the aluminum substrate of the LED diffuse reflector light bar are as follows.

LED diffuse reflector strip aluminum substrate adopts surface mount technology (SMT);

The aluminum substrate of the LED diffuse reflection light strip is extremely effective in dealing with heat diffusion in the circuit design scheme;

The aluminum substrate of LED diffuse reflector can reduce the operating temperature of the product, improve the power density and reliability of the product, and prolong the service life of the product;

LED diffuse reflector strip aluminum substrate can reduce product volume and reduce hardware and assembly costs;

LED diffuse reflector strip aluminum substrate replaces fragile ceramic substrate for better mechanical durability.

LED diffuse reflector light strip aluminum substrate is a metal circuit board material, which is composed of copper foil, thermal insulation layer and metal substrate. Its structure is divided into three layers:

Circuit layer: equivalent to the copper clad laminate of ordinary PCB, the thickness of circuit copper foil is loz to 10oz.

Insulating layer: The insulating layer is a layer of thermally conductive insulating material with low thermal resistance. Thickness: 0.003" to 0.006" inch is the core technology of the aluminum substrate of LED diffuse reflector light bar, which has obtained UL certification. Base layer: It is a metal substrate, usually aluminum or copper. Aluminum base copper clad laminate and traditional epoxy glass cloth laminate, etc.

LED diffuse reflector strip aluminum substrate is suitable for surface mount SMT public art of power components. No radiator is needed, the volume is greatly reduced, the heat dissipation effect is excellent, and the insulation performance and mechanical performance are good.

The above is the introduction of the aluminum substrate of the LED diffuse light strip.
