<P>PROBLEM TO BE SOLVED: To provide a lighting device that has a heat dissipation element, at least one light-emitting module, and a speaker. <P>SOLUTION: The heat dissipation element 11 has: a first housing groove 111; a second housing groove 112; and a first passage 113 communicated with the first housing groove 111 and the second housing groove 112. The light-emitting module 12 is installed at the first housing groove 111 and stuck on the heat dissipation element 11. The speaker 13 has a thin film 19 and is installed in the second housing groove 112. When the speaker 13 emits sound, the thin film 19 is vibrated, so that a first air current which passes through the first passage 113 from the second housing groove 112 and flows to the first housing groove 111 is formed. The lighting device 1 promotes air in the first housing groove 111 to flow by vibration of the speaker 13, and furthermore, heat dissipation effect is improved. <P>COPYRIGHT: (C)2011,JPO&INPIT |
