The present disclosure provides an artware with a water stirring function and a projection function. The artware includes a housing structure, a control circuit board including a switch, a magnetic rotating unit controlled by the control circuit board, and a projection unit controlled by the control circuit board. The control circuit board, the magnetic rotating unit, and the projection unit are arranged in the hosing structure.

There is disclosed a tubular lighting device (20) comprising: an elongated tubular member (2) with an elongated light exit window (3) having a central area (3a) and two peripheral areas (3b, 3c); a first end cap (4); a second end cap (5); and a plurality of LEDs (9). Light exiting from the central area (3a) has a maximum intensity in a main illumination direction (I) of the tubular lighting device (20), and light exiting from each 5 peripheral area (3b, 3c) has a maximum intensity in a direction which is inclined away from the main illumination direction (I) and towards the closest end cap (4, 5). Thereby, when the tubular lighting device (20) is mounted in a luminaire behind a light exit cover, the uniformity of the intensity distribution of the light falling on the light exit cover is increased. luminaire is also disclosed.

A lighting system having a transformer and a gripper. The lighting system has a lighting assembly having a light transmission element and an LED engaged and attached to the light transmission element. The light transmission element is made of a material that is transparent to light and which is lit by the LED. The lighting system has a suspension electrical wire electrically connected to the LED and extending from the gripper. The lighting assembly suspended from the gripper by way of the suspension electrical. The gripper holding the suspension electrical wire and attaching the suspension electrical wire to an object. The transformer provides power to the LED through the suspension electrical wire to which it is electrically connected by another electrical wire. A lighting assembly. A method for lighting

A lighting apparatus and method for making the same are presented. In some aspects the apparatus includes a plurality of LED light sources mounted to a metal circuit board in a housing of the apparatus. In other aspects a light-permissive potting compound is disposed in the space between the LEDs and circuit board and the housing of said apparatus so as to permit exit of light from said LEDs while providing mechanical protection for the circuit board and LEDs and removing heat generated from said LEDs.

An optical water curtain system includes a water supply portion, at least one water collecting portion, a physical rotor, a control module, and an LED light-emitting module and a rotation speed detecting module. The water supply portion is in fluid communication with the water collecting portion, and the water collecting portion has outlets through which water flows down to form a water curtain. The LED light-emitting module emits light to illuminate the water curtain. The physical rotor is located within the water curtain and rotatable under an impulse of a water flow from the water curtain. The rotation speed detecting module detects a rotation speed of the physical rotor and send data to the control module. The control module adjusts a frequency of a PWM signal driving the LED light-emitting module to switch a light-emitting effect of the LED light-emitting module according to the rotation speed of the physical rotor.
