<p>A loudspeaker and an alarm with a luminous element are provided, which are improved based on the original loudspeaker and luminous element. The luminous element is an illuminating lamp, while a heat radiator is mounted near the illuminating lamp. Due to the addition of a heat radiator, a light source with a larger power could be selected as the luminous element, making the loudspeaker have the function of illumination so as to substitute the former illuminating lamp within the place. Also, employing an alarm made with the loudspeaker, using the bright light emitted by the illuminating lamp on each loudspeaker, it makes better for illumination, as well as making each illuminating lamp twinkle according to the direction pre-programmed, so as to achieve the purpose of directing a direction, and help people escape rapidly from a dangerous place. Further, in the case when the external power source is broken, by means of the built-in emergency power source, the loudspeaker and the illuminating lamp can still be ensured to work normally.</p> |
