An underwater directional light is provided. The directional light includes a lamp assembly, a tube assembly, and a printed circuit board assembly. The lamp assembly includes a housing and a lamp having a plurality of lighting elements. The tube assembly is coupled to the lamp and has a hollow interior. The printed circuit board assembly is mechanically coupled to the tube assembly and electrically coupled to the lamp.

An optical member includes a light source, a first substrate to be a light guide that guides emitted light from the light source, a variable layer in contact with a predetermined surface of the first substrate, and a second substrate facing the first substrate via the variable layer. When a refractive index of the first substrate is n1, a refractive index of the variable layer can be changed to n2 or n3 (where n2>n3), and n1, n2, and n3 satisfy a relationship of |n1−n2|<|n1−n3|.

An optical component has: a planar liquid layer; and one or more light sources arranged such that light is guided to the planar liquid layer; wherein the liquid layer is configured to guide light.

The present disclosure discloses a lamp for water mist in the shape of a flame, which includes a base, wherein a water tank is arranged on the top of the base, an ultrasonic atomizer is provided at the bottom of the water tank, an upwardly protruding component is centrally arranged at the bottom of the water tank, a plurality of supporting blocks are arranged at the bottom of the spacer plate near the through hole, and a baffle plate is arranged between the supporting blocks and the protruding component, a channel is formed between the spacer plate and the baffle plate, and a plurality of LED lights are provided on the top of the water tank, a housing is provided outside the water tank, the top part of the housing is provided with a top cover having a lamp hole.

A flower receptacle with a water lamp handicraft, including: a water lamp ornament, where the water lamp ornament includes a water lamp body and a top ornament, and the water lamp body is a hollow and a light-transmissive three-dimensional structure and holds a thick liquid inside, and the top ornament is mounted on the water lamp body; a fixing member, connected to the top ornament, and forming a customized three-dimensional model with the top ornament; and a flower receptacle base, having a tapered structure, mounted on the fixing member, and used for arranging flowers. In the present application, the fixing member and the top ornament are combined, to enable the fixing member and the water lamp ornament to form a unique three-dimensional model.

A water-globe decoration light-and-shadow pedestal structure includes a pedestal to which a water-globe decoration is attachable. The pedestal is provided, in an interior thereof, with light-emitting elements. The pedestal has a wall that is formed with at least one hollowed pattern. The water-globe decoration is of a light-transmitting three-dimensional configuration and has a sealed interior space that receives and holds therein a flowable liquid. Height differences of the light-emitting elements relative to the at least one hollowed pattern allows light to pass through the at least one hollowed pattern of the pedestal to project a shadow of the at least one hollowed pattern onto an object outside the pedestal, so as to generate a lighting and shadowing visual effect that is rich and shows variation of layering.

A resistance water lamp includes: a main body, made of plastic material, and being a transparent hollow three-dimensional type, low boiling point liquid filled in an inside thereof, and an accommodation tank, fixed to one side of the main body, an inside thereof provided with an electric control unit including at least one electric heater and power source, the electric heater positioned correspondingly to the side of the main body, and power thereof provided by the power source, the electric heater producing a thermistor effect and generating heat energy when the electric heater is energized, thereby driving the liquid inside the main body to generate relative flowing with the heat energy.

The present invention relates a solar-powered, floating, fountain lamp, comprising a light-emitting elements, a fountain housing, and a solar panel, and the fountain housing acts not only as a three-dimensional lampshade for a first light-emitting portion, but also as a floating portion of the fountain lamp, and the fountain housing is substantially formed by a saucer-shaped cabin and a cylindrical lower part that are integratedly connected to each other, in which the saucer-shaped cabin located in an axially upper part of the fountain housing has an outer peripheral surface that is smooth and curved, and the plurality of light-emitting elements each project a light beam in a different direction, and the light-emitting elements projecting the light beams outward the fountain housing form point light sources at a top of the fountain lamp, the point light sources on the top act as a second light-emitting portion, and the light-emitting elements projecting the light beams inward the fountain housing form the first light-emitting portion, and the first light-emitting portion provides uniform lighting through the three-dimensional lampshade formed by outer walls of the saucer-shaped cabin and of the cylindrical lower part that are smoothly connected.
