What are the requirements for outdoor decorative light source heat sinks

In order to create an energy-saving and efficient smart lighting system, the use of MCUs and dimmable drivers for environmental sensing and high-efficiency dimming has become a prevailing design trend for LED Christmas Decoration Lights systems. In addition, the simulation of optics and heat dissipation is also It is an indispensable development link to ensure the reliability and safety of decorative lighting products. On the other hand, it is even more important to verify the feasibility of the product through the simulation process of optics and heat dissipation. This not only ensures product safety, but also accelerates the development schedule of the product during the simulation process and enhances market competitiveness. .

With the increasing popularity of decorative lights, the applications are becoming more and more diversified. Among them, the business opportunities of smart lighting systems are more anticipated by the industry. In order to create an LED smart lighting system, the introduction of MCU can realize functions such as automatic brightness adjustment, automatic color conversion, environmental sensing, and group system control, enriching the applicability of LED lanterns and improving energy efficiency. The investment in construction cost should be based on the size of the main body of the lighting building and the requirements of the investor as the starting point. If the construction cost is too large, it may daunt the unit that intends to implement the lighting and lead to abandoning the investment in the lighting. Therefore, the construction cost investment should be integrated first Consider, fully select famous products with good product quality, safety and reliability. Secondly, from the perspective of economy, reasonability and necessity, reasonably configure high-, medium-, and low-end price products, and make a comprehensive analysis of the materials and construction budget of the lighting plan, so that the overall effect is economical and beautiful.


Requirements for heat sinks of outdoor decorative lighting sources. Appearance and raw materials: If the sealing requirements of the product are not high, convection can occur directly with the outside air environment. It is more recommended to use finned aluminum or copper heat sinks. Outdoor decorative light source LED high-power connection method: When connecting the high-power LED substrate of the outdoor decorative lamp and the heat sink, please ensure that the touch surfaces on both sides are flat to make the combination of the two touch surfaces more suitable. It is recommended to be at the bottom of the outdoor decorative lamp substrate or heat dissipation A layer of thermal conductive silicone grease is applied to the surface of the chip. The thermal conductive silicone grease needs to be applied evenly and appropriately, and then fixed with screws.

Modeling lamp manufacturers about outdoor decorative lights 1W high-power LED white light (other colors are basically the same) heat sink is generally useful for heat dissipation and the total surface area is ≥50 square centimeters. Regarding 3W products, the recommended heat sink has an effective heat dissipation surface area of ​​≥150 square centimeters. A factor for higher-power visual modeling lamp manufacturers to choose holiday decorative lights can make energy-saving lamps or traditional tungsten filament lamps not very cost-saving. The cost of electricity is on the rise, there is an option to make the festival alive with holiday decoration lights and holiday lights. These lamps are not only cost-effective, but also brighter and more durable than traditional energy-saving lamps.
