A runway-embedded flash lighting device includes, a body configured for embedding in a runway, a ceiling member with a flash emission window, a bottom cover member, a light guide member disposed in the flash emission window, and two or more flash emission windows. The light guide member is disposed in each of the flash emission windows and an inner surface of the ceiling member is provided with a site to be disposed with a LED flash light source below the flash emission window. The LED flash light source includes, an LED module, a frame-shaped attaching plate; and a lens member. The lens member is attached to a hollow portion in a frame of the frame-shaped attaching plate, and is configured to allow an emission surface of the flash emitted from the LED module to have a uniform illuminance distribution.

A projection device for ambient decoration may include a first light-emitting assembly comprising at least one first incoherent light source, a reflective medium, and a first driving device. The first light-emitting assembly may further include a mount recessed internally to define a placing groove adapted to the reflective medium, a first through-hole and a placing recess on one side of the first through-hole arranged at a bottom of the placing groove, a fixing column arranged in a center of the placing recess, and a second through-hole arranged at a bottom of the reflective medium. The first driving device may be coupled to the reflective medium, the fixing column may pass through the second through-hole into the reflective medium, and the at least one first incoherent light source may be connected to the fixing column.

An LED projection lamp includes a light-emitting assembly and a main body. The light-emitting assembly at least includes a light source for generating light, and a rotating body disposed on a light path of the light for enabling the light to present a first effect. The main body includes an accommodating cavity for accommodating the light-emitting assembly. The main body includes a lens and a light-transmitting sheet, the lens emits a light having the first effect, and the light-transmitting sheet emits the light. A light-blocking member is disposed on an outer portion of the light-transmitting sheet, a light-transmitting hole is defined on the light-blocking member, and the light-transmitting holes enables the light to present a second effect.

A space projection lamp includes the convex lens, an uneven reflective plate, motor, light source, integrated main control and power input. The bottom surface of the uneven reflective plate is fixedly connected with the output shaft of the motor. The convex lens and the light source are respectively arranged on both sides of the uneven reflective plate. The light emitted by the light source passes through the convex lens after being reflected by the uneven reflective plate. When the light source irradiates the uneven reflective plate from the side, the reflection is projected out through the imaging of convex lens, forming a layered light effect. When the motor rotates with uneven reflective plate, it will form a multi-level dream light effect.
