Systems, apparatus, and methods related to recreational balls with illuminated surfaces are described herein. In some embodiments, an apparatus includes an air-tight object having an outer layer and an inner layer. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines an aperture. Additionally, a light module is configured to send light from an interior of the air-tight object through the aperture of the outer layer.

Disclosed is an inflatable soft box, which belongs to the technical field of photography and film and television. The present application compromises a flexible case. An inflatable nozzle is provided on the flexible case, and the inflatable nozzle is used to inflate or deflate the flexible case. A soft lamp is provided on the flexible case, and the soft lamp is used to illuminate the flexible case. The structure of the inflatable soft box of the present application is simple. By providing an inflation nozzle on the flexible case, the flexible case is inflated by the inflation nozzle when in use, and the flexible case is inflated; when not in use, the flexible case is deflated by the inflation nozzle, making it easy to carry or move, and convenient for users to use.

Disclosed is a lighting tower (100) with a Light Emitting Diode (LED) (106). The lighting tower (100) comprises a Base Unit (102), an inflatable balloon (104), a blower (108), and a stabilizing rod (114). The inflatable balloon (104) is coupled to the Base Unit (102). The LED array (106) coupled to a top end of the inflatable balloon (104) with inward facing of the LED (106) in the inflatable balloon (104). In one aspect, the blower (108) lifts up the inflatable balloon (104) with the LED array (106). In another aspect, the blower (108) simultaneously controls a temperature at a junction of the LED (106).

A low wattage balloon work light includes an illumination unit with a light-emitting diode (LED) light bank in the range of 30 watts to 300 watts, an inflatable balloon, and a power cord to power the low wattage balloon work light.

Systems, apparatus, and methods related to recreational balls with patterned illuminated surfaces are described herein. In some embodiments, an apparatus includes an air-tight object having an outer layer and an inner layer. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines an aperture. Additionally, a light module is configured to send light from an interior of the air-tight object through the aperture of the outer layer.

A screw type light-emitting device comprises a hollow mounting holder; a screw holder disposed over the mounting holder and threadedly connected with the same; a battery case disposed in the mounting holder and relatively fixed with the same; a battery pack removably disposed in the battery case 30; an LED light disposed at one end of the battery case and extending out of the mounting holder, wherein one of the electrodes of the LED light is electrically connected to the battery pack, and the other electrode extends to between the battery pack and the screw holder; both the LED light and the battery pack are mounted in the battery case, the battery case is mounted in the mounting holder, and the mounting holder is threadedly connected with the screw holder, and the LED light will emit light when the screw holder is rotated into a proper position.

An inflatable decorative system includes an inflatable hollow bag body provided with an inflation port and a line hole, a plurality of first fixing portions having perforations or hook portions and arranged on an inner wall of the bag body, and a light string system. At least an end portion extends out of the bag body from the line hole, and the remaining portions are arranged inside the bag body and fixed among the plurality of first fixing portions so that the light string system is unfolded into a preset shape in the bag body after the bag body is inflated. The light string system can be directly hung among the plurality of fixing portions, and can also be fixed among the plurality of fixing portions by a reinforcing strip or reinforcing line.

Lighting devices are described and may include a housing that includes one or more end walls and one or more side walls, the housing defining a chamber and a base. The lighting devices may include one or more of a solar panel, a rechargeable battery, a microprocessor, a wireless interface, and/or a plurality of lights, in communication with one another. The plurality of lights may be configured to emit light transverse to the one or more side walls, the lighting device also including a diffuser configured to diffuse and redirect light emitted by the plurality of lights into the chamber. The microprocessor may be configured to control at least one operating mode of the plurality of lights.
