LED lighting device with speaker function, method of extracting light and sound from LED lighting device with speaker function

摘要

A frame member (3) is attached to the opening of the outer light reflection plate (11). The frame member (3) includes an inner frame portion (3b) and an outer frame portion (3a) disposed around the inner frame portion (3b). A light extraction portion (5) is formed between the outer frame portion (3a) and the inner frame portion (3b). The inner frame part (3b) is composed of another extracting part (7) for extracting acoustic vibration and light. The space (9c) of another take-out part (7) is opened toward the outside of the LED lighting device (1) with the sound intake (9b) on the internal space side where the sound source (17) is arranged. It has a sound outlet (9a) formed at the top of the inner frame (3b) at both ends. The sound inlet (9b) and the sound outlet (9a) are formed to be separated from each other by a predetermined distance, and the inner frame (3b) has a sound inlet (9b) and a sound outlet (9a). Are connected to each other to form a continuous space (9c).
