The present application discloses a light-emitting device for rotationally delivering liquid upward, which comprises: a motor, a first magnetic part, an inner chassis, a chamber shell, a second magnetic part, a rotating module, and a light-emitting assembly. Due to the cooperation, the rotating wheel blades and the rotating column blades, the rotating wheel blades can firstly stir the water flow at the bottom of the liquid chamber in a large area and at high efficiency, and then the rotating column blades cooperate to rotate and deliver the water flow upward stably and continuously to the top of the liquid chamber, so that the entire interior of the chamber is always filled with spirally rising water flow. Therefore, the entire dynamic projection effect of the lamp is better, the atmosphere effect is stronger, and the user experience is better.

The present disclosure provides a candle lamp (10). The candle lamp (10) comprises a lamp body (100), a wick (200), a base (310), and a power driver board (320). The wick (200) and the base (310) are disposed at opposite ends of the lamp body (100) along a longitudinal direction thereof. The power driver board (320), together with the base (310), is secured to a bottom portion of the lamp body (100). This configuration of the candle lamp (10) provides a stable connection, preventing unintended detachment of the base (310) and the power driver board (320) from the lamp body (100).

[Problem] To improve the degree of freedom of dramatization in which the afterimage effect of water droplets is utilized. [Solution] While water droplets W are intermittently produced by a water droplet production device 10, light is beamed onto the water droplets W along the travel path of the water droplets W by an illumination device 20. An illumination device with which it is possible, when each cycle by which light is beamed onto the water droplets W is split by time into a plurality of sections, to control the light emission state for each of the sections, is employed as the illumination device 20. It is thereby made possible to, e.g., cause a single droplet to shine in multiple colors or freely change the size or movement of afterimages of the water droplets viewed by a viewer.

A roof-mounted emergency beacon used to alert emergency responders and observers of the location of an emergency. The beacon is activated by a smoke alarm, burglar alarm, or medical emergency alarm. Upon activation, the beacon light flashes, and the beacon extends to increase visibility. The beacon illuminates different colors to indicate different types of emergencies. Upon deactivation, the beacon lowers to return to the stowed position.

A kit for removably attaching a string of lights to a roofline, the kit comprising: first magnets of a first magnetic force; screws configured to pass through apertures of corresponding first magnets to fasten the corresponding first magnets to respective points on the roofline; metal tabs configured to magnetically couple to the first magnets; rings configured to secure respective metal tabs to the string of lights; and a pole configured to hoist the string of lights to the roofline, wherein the pole includes a second magnet on a distal position on the pole that magnetically couples to the metal tab when raising the string of lights to the roofline, wherein the second magnet has a lower magnetic force than the first magnet.
