DeutscheJewelry showcase lighting, display cabinet lighting, cabinet lighting, wardrobe lighting, specialty store decorative lighting, light art lighting, advertising light box lighting and street lights, hotels, guesthouses, home villas decorative lighting, etc. led smd tube light by FPC circuit board , LED lights, high-quality silicone sleeves. Waterproof performance, safe and convenient to use low-voltage DC power supply, luminous colors are diverse, bright colors; outdoor use can resist UV aging, yellowing, high temperature resistance and other advantages. This product is widely used in building contour lights, entertainment venues quasi-decorative lighting, and advertising decoration Lighting field. The thermal resistance of the LED package has a decisive influence on the life of the LED chip, especially for the LED chip driven by high current. The cost and heat dissipation performance of the LED package product depends on the structure of the package bracket, and the package bracket is small in size and thin in thickness. , Development in the direction of good heat dissipation.
The heat dissipation problem must be considered when packaging more LED chips in a single SMD LED. The most important advantage of high-power SMD LEDs with high thermal conductivity metal-ceramic composite substrates is ultra-low thermal resistance. Viahay launched in January 2010 New surface mount white LED. Using PLCC-4 package, the optimized lead frame makes the thermal resistance as low as 300K/W, and the power dissipation is as high as 200mW, so that the device can use up to 50mA drive current, so that the brightness can reach Vishay's high-brightness sMDLED using PLCC-2 package. Twice "'. Ultra-low thermal resistance and high-power LED chip package is small and thin. It is more suitable for applications with small space. This feature brings great convenience to many applications. Compared with other LED chip packages In comparison, when it maintains the same junction temperature, the requirements for heat dissipation components are reduced, and when the same heat dissipation components are used, the junction temperature is reduced and the life of the LED package is prolonged.
