Abstract

Disclosed is an acoustic light fitting, wherein the light source is composed of a spherical dust cover (7) of a speaker and a light-emitting body below the dust cover. The spherical dust cover is light permeable but not air permeable. The surface of the spherical dust cover has been sandblasted or textured and the light-emitting body is not visible. The spherical dust cover is fixedly mounted on a cone (8), and the dust cover and the cone together form a sound source. The resonance space required to improve the bass effects of music is formed by the box body carried in the light fitting itself or the space provided where the acoustic light fitting is mounted. The resonance space for bass in a floor acoustic light fitting is formed by a labyrinth box body (9) of the light fitting, and the top end of the box body is provided with an acousto-optical separator (1), dispersing mid- and high-range frequencies all around and dispersing light upwards, and preventing glare. The resonance space for bass in a ceiling acoustic light fitting is formed by a vent hole (11) at the back of the light fitting and a ceiling mounting space, light and sound waves being dispersed all around from the spherical dust cover and the cone.

The mature application of efficient and long-life new light sources creates a prerequisite for acousto-optic products. SUMMARY OF THE INVENTION

[0003] The object of the present invention is to design a self-contained luminaire that integrates sound and illumination for easy decoration and repair, while creating conditions for popularizing and promoting home theater and surround sound.

[0004] The technical solution of the present invention is to use a lamp with a light as a light source and a sound source, and cooperate with the corresponding lamp structure to integrate optical technology and acoustic technology, and implement lighting standards, energy saving standards and acoustic standards in one product. In the middle, it forms an acoustic luminaire suitable for different occasions.

[0005] The light source of the audio lamp is a ball of a speaker and a light cover of the dust cover and the dust cover. The sound source is a dust cover and paper fixedly mounted on the paper cone and vibrating with the paper cone.

The illuminator is built into the underside of the spherical dust cover. The dust cover is light-tight and airtight, and the air in front of and behind the paper cone is isolated from the paper cone to prevent short-circuiting of high-frequency sound waves. The surface of the spherical dust cover is sandblasted or embossed to prevent the illuminant from being exposed. The dust cover is fixed on the paper cone and is driven by the speaker voice coil to vibrate with the paper cone to generate sound waves.

[0006] In the application of the acoustic luminaire in the floor-standing audio luminaire, the 3⁄4 illuminator diffuses the medium-high frequency Lubo to the surrounding, diffuses the light upward, and prevents the glare. The illuminated speaker is mounted face up and the light is illuminated upwards. At the top of the floor-standing audio luminaire, a sound and light separator is specially designed. The acousto-optic separator consists of a light guide plate and a beam splitter. The beam splitter is located at the top of the acousto-optic separator;

Use the labyrinth box of the luminaire to assist and invert the low frequency sound waves

[0007] In the application of the ceiling luminaire, the sound illuminator uses the through hole structure behind the luminaire, and the person who installs the ceiling I'Hj is a low frequency sound wave. The illuminated speaker light is mounted face down. The front of the luminaire is accessible, and the light and sound waves spread out through the spherical dust cover. The reverse side of the luminaire is designed with a venting hole to communicate the reverse side of the audio light cone with the ceiling installation space of the ceiling sound fixture to create a large baffle effect and improve the bass effect of the ceiling sound fixture.

[0008] The audio luminaire can be internally integrated with a power converter, a light source driver, a power amplifier, and various signal sources or transmission modules. [0009] The audio lamp designed by the present invention has the following advantages:

[OOlOj l. The combination of sound and light of audio lamps reduces the ground installation space compared with the traditional audio, increases the air installation space, and expands the sound application environment and scope of use.

[001 1 ]2. The acoustic design of the acoustic luminaire that spreads 360 degrees around, improves and expands the optimal listening area for stereo and surround sound.

[0012J3. Audio lamps are the popularization and promotion of digital surround sound, creating more favorable hardware conditions. DRAWINGS
