A plant illumination device may include an elongate body comprising: a light propagating section, a light quenching section coupled to a first end of the light propagating section, and, optionally, a light conducting apex coupled to a second end of the light propagating section. In some embodiments, the light conducting apex acquires light which propagates to the light propagating section. The light propagating section may be positioned in proximity to a non-root portion of a plant and the light quenching section in proximity to a root system of the plant. In some embodiments, the light is prevented from reaching the root system of the plant by the light quenching section. In some embodiments, the light includes sunlight, green light, or red light.

A light emitting diode (LED) tube lamp configured to receive an external driving signal includes an LED module for emitting light, the LED module comprising an LED unit comprising an LED; a rectifying circuit for rectifying the external driving signal to produce a rectified signal, the rectifying circuit having a first output terminal and a second output terminal for outputting the rectified signal; a filtering circuit connected to the LED module, and configured to provide a filtered signal for the LED unit; and a protection circuit for providing protection for the LED tube lamp. The protection circuit includes a voltage divider comprising two elements connected in series between the first and second output terminals of the rectifying circuit, for producing a signal at a connection node between the two elements; and a control circuit coupled to the connection node between the two elements, for receiving, and detecting a state of, the signal at the connection node. The control circuit includes or is coupled to a switching circuit coupled to the rectifying circuit, and the switching circuit is configured to be triggered on or off by the detected state, upon the external driving signal being input to the LED tube lamp, to allow discontinuous current to flow through the LED unit.

One embodiment provides a system, including: a first end that screws into a light bulb socket; an internal light source; an electric insect control mechanism disposed around and proximate to the internal light source; and a visible light source disposed at an opposite end with respect to the first end. Other embodiments are described and claimed.

In an aspect, a toy figurine for displaying an animated light pattern includes a main body, a plurality of light-emitting elements inside, and a controller. The light-emitting elements, when unilluminated, are invisible to a user outside the main body, and, when illuminated, are invisible to the user but emit light that is visible through a window of the main body. The controller is programmed to: a) illuminate a first light-emitting element at a first element illumination rate so as to emit first light through the window, b) illuminate a second light-emitting element at a second element illumination rate so as to emit through the light-diffusive window, second light which overlaps with the first light, and c) after step b) has begun, deilluminate the first light-emitting element at a first selected deillumination rate, so as to generate an appearance of light that travels along the window.

Techniques for creating, configuring, and employing diffusion light devices are presented. Such light device(s) can comprise or be associated with a light management component (LMC) that can employ sensors to monitor environmental conditions in a defined area of people or vehicles, and a diffusion component that can diffuse or otherwise process light. At a least a portion of the diffusion component and/or a light component can be formed of a fabric that can emit light and/or diffuse light. LMC can enhance function of the light device to manage diffusion of light or perform other tasks to enhance user experience and safety and security of people or vehicles. Based on results of analyzing sensor data relating to the conditions, LMC can determine and facilitate implementing an adjustment(s) to a parameter(s) of the diffusion component or light component to achieve desired emission or diffusion of light.

A structural element, including a base portion and a connecting central pin, has its base portion formed hallow, and having an internal reinforcement in the shape of WOW or MOM, to connect these elements with an insertable central pin so that the cross-section of the pin corresponds to the shape of the chamber between the reinforcements, when the upper surface of the structural element has longitudinal grooves, and is made from a modified polymer or elastomeric material comprising India rubber mixtures. The foundation is monomer ethylene propylene diene or natural rubber or styrene-butadiene rubber and/or combinations of the natural rubber/styrene-butadiene rubber, or thermoplastic elastomers, whose base is monomer ethylene-propylene-diene or polypropylene/monomer ethylene-propylene-diene or polyvinylchloride, or thermoplastic vulcanizates, whose base is monomer ethylene-propylene-diene and polyethylene or natural and/or synthetic rubber, modified by polyethylene or polypropylene.

A zoom lamp includes a lamp body, a light emitting component, a movable ring, a lens, and a rotation ring. The lamp body defines a receiving groove. The movable ring includes a plurality of guiding posts protruding from an outer wall thereof and a plurality of resilient members. The lens is fixed to the movable ring. An external wall of the rotation ring is provided with a latching hook, the rotation ring defines a plurality of inclined grooves. When the rotating ring rotates, the guiding post is guided by the inclined groove to slide, thereby driving the lens to move adjacent to or away from the light emitting component.
