Description

  The present invention relates to a kind of acoustic lighting device belonging to the field of lighting technology.

  Along with the development of multimedia in electronic products, mobile phones are combined with communications, networks, music, cameras, etc., and diversified multimedia products have become popular. Development of a product that combines sound and lighting has been carried out on the premise of the maturation and spread of applications of new light sources with high efficiency and long life.

  An object of the present invention is to create a condition for creating a sound effect with a widespread presence of home theater and a sense of realism by integrating sound and lighting in the design of attaching a sound device to a lighting fixture, and for the convenience of decoration and interior decoration. is there.

  The technical solution of the present invention uses a speaker having illumination as a light source and a sound source, combines a structure of a lighting device suitable for it, fuses optical technology and acoustic technology, and combines lighting requirements, energy saving requirements, and acoustic requirements into one. Provide an acoustic luminaire that is realized in the product and adapted for use in various places.

  The light emitter of the acoustic lighting device is installed under a spherical dustproof cover. The dust-proof cover is transparent to light and sealed, blocking the air before and after the cone with the speaker cone, thereby preventing short-circuit sound short-circuit. The surface of the dust cover is polished and vitrified or subjected to a pattern treatment so that the illuminant cannot be viewed directly. The dust cover is fixed to the cone, and is driven by a speaker coil, vibrates together with the speaker cone, and emits sound. The dust cover and speaker cone are also the sound source of the illuminated speaker.

  When the acoustic lighting device is used as a floor-mounted acoustic lighting device, the speaker with illumination is arranged upward and the light is irradiated from below to above. A sound / light separation device is installed at the top of the floor-mounted acoustic lighting fixture. The sound / light separation device includes a light guide plate and a spectroscopic sphere. The spectroscopic sphere is located on the top of the sound / light separation device. When using a sound / light separation device, mid- and high-range sounds diffuse around and light diffuses up to prevent glare. In order to enhance the bass, the floor-mounted acoustic luminaire housing is designed to provide an acoustic maze.

  A power converter, a light source driver, a power amplifier, various signal sources, and a processing module can be built in the acoustic lighting device.

  The acoustic lighting device designed according to the present invention has the following merits.

  1. The acoustic lighting device is characterized by the combination of sound and light, and it has a smaller space than conventional acoustic devices, and has expanded the usage environment that can accommodate the degree of freedom of installation.

  2. The design that diffuses to 360 ° around the acoustic lighting device improved the surround effect and expanded the audible range of the surround effect.

  3. The acoustic lighting device created a hardware condition for the popularization of digital surround sound systems.

  Embodiment 1

  1 to 8 show a floor-mounted acoustic lighting apparatus according to the present embodiment.

  The floor-mounted acoustic lighting apparatus according to the present embodiment includes a sound / light separation device 1, a speaker with illumination 5, a maze housing 9, a bottom box 15, and a stand 17.

  The sound / light separation device 1 of the present embodiment includes a spectroscopic sphere 2 and a light guide plate 3, and the light guide plate 3 has a polished glass treatment or a film attached to the surface. Therefore, the light is dispersed and glare is prevented. The screw 4 determines the distance between the light guide plates and fixes the sound / light separation device to the maze housing 9. The spectroscopic sphere 2 and the light guide plate 3 diffuse middle and high frequency sound around.

  The illuminated surface of the illuminated speaker 5 of the present embodiment is installed upward. The light emitter 6 in the illuminated speaker 5 is disposed under a spherical dust-proof cover 7 that is transparent to light and sealed. The spherical dust cover 7 is fixed to the cone 8 and vibrates together with the cone 8. The spherical dustproof cover 7 and cone 8 are the sound source of the illuminated speaker.

  The inner cross section of the maze housing 9 of the present embodiment is equally divided into five maze cavities. The respective maze cavities are connected to each other via the vent 11. The vent hole 11 at the center of the maze upper cover 12 serves as an entrance for low-frequency sound emitted from the back surface of the cone of the illuminated speaker. An illuminated speaker 5 and a sound absorbing material 13 are arranged in a space between the maze upper cover 12 and the chassis plate 10. The sound absorbing material 13 reduces the standing wave on the back surface of the cone. The vent 11 in the labyrinth bottom plate 14 is the exit of the labyrinth path and allows bass sound waves to flow through the bottom box 15.

  A plurality of holes 16 are provided in the side surface of the bottom box 15 of the present embodiment. The total area of the holes is approximately equal to the area of the maze vent. The hole 16 is a low-pitched sound outlet and at the same time prevents insects and foreign objects from entering the housing.

  The stand 17 according to the present embodiment is connected to the bottom box 15 and the maze housing 9 integrally using a connecting screw 18. Rubber feet 19 are provided on the stand 17 to prevent vibration.
