LED的設計目的是使其光線聚焦，無需使用外部反射器即可將其定向到特定位置，從而實現比傳統照明更高的應用效率。精心設計的LED照明系統能够更有效地將光傳送到所需位置。

結果 (英文) 1:

LED it is designed to focus light, without the use of an external reflector to be directed to a specific location, thereby achieving a higher application efficiency than traditional lighting. LED lighting system designed to more efficiently transmit light to a desired location.

結果 (英文) 2:

Leds are designed to focus their light and direct it to a specific location without the need for an external reflector, resulting in greater application efficiency than conventional lighting. Well-designed LED lighting systems deliver light more efficiently to the desired location.

結果 (英文) 3:

LED is designed to focus its light, and it can be oriented to a specific position without using an external reflector, so as to achieve higher application efficiency than traditional lighting. The well-designed LED lighting system can more effectively transmit light to the required location.
