A flashlight, including: a lens assembly having an adjusting lens; and a light source assembly provided at one side of the lens assembly, the light source assembly comprising a first light source, a second light source, an excitation element, and a light path adjusting element. Light emitted from the first light source irradiates the excitation element to generate first exciting light, and light emitted from the second light source irradiates the excitation element to generate second exciting light. The first exciting light and the second exciting light sequentially pass through the light path adjusting element and the adjusting lens and then are outputted in parallel. The flashlight can integrate the advantages of the first light source and the second light source, to provide the light source with excellent light emitting performance.

An underwater diving light with efficient waterproof performance includes a top cover, a bottom cover, a light-emitting assembly and a special-shaped light-transmitting seal. A first installation groove is formed in the top cover. A second installation groove is formed in the bottom cover. The special-shaped light-transmitting seal includes a light-transmitting waterproof part, a first installation part and a second installation part. The first installation part, the light-transmitting waterproof part and the second installation part are all annular and connected in sequence. The top cover and the bottom cover are movably connected to form a light housing. The light-emitting assembly is arranged in the light housing. The underwater diving light has the advantages of strong waterproof and moisture-proof performance, diversified luminous forms and a dazzling effect.

Provided is a fixture including a base; and a light guide, which is positioned on the base and is configured to receive light emitted from a light source in a first direction and guide the received light to be emitted in a second direction crossing the first direction.

A portable light may comprise: a light housing including a first housing and a light head that is pivotable relative to the first housing; one or more light sources including an illumination light source in the light head; an electrical switch for selectively energizing the one or more light sources; and a detector of the pivoted position of the light head relative to the first housing for energizing and/or de-energizing one or more of the light sources. Other features of the light may include: a rear facing light source that may have one or more light sources, or an elongated clip, or a pivotable elongated clip, or one or more accessories mountable to a clip, or a combination thereof.

A portable linear worklight for converting point light into a linear light source is disclosed. The portable linear worklight comprises a worklight body and a lens. A transparent light pipe is positioned between an upper reflector and a lower reflector inside the worklight body. The lower reflector holds the light pipe and reflects light back into the light pipe. A light emitting diode in a battery housing emits light into a light receiving end of the light pipe. The received light travels trough the light pipe and is emitted from a light emitting surface of the light pipe. The upper reflector reflects some of the light emitted from the light emitting surface and directs the light toward the lens and the light exits the worklight body.

A lighting device with improved optical performance and efficiency is provided. The lighting device includes a source of energy, a light source, a reflector and a holder. The reflector has a first open end, a second end, and a parabolic profile extending between the first open end and second end. The focus of the parabolic profile is located outside of the profile. The reflector may also be movable relative to the light source. The lighting device may include a circuit that delivers a pulsed or thermally compensated pulsed current to the light source. The light device may also include a heat sink housing.

A portable indirect lighting apparatus includes first and second support structures. Each support structure includes a respective longitudinal light source having a linear array of light-emitting diodes (LEDs). A respective longitudinal lens is positioned proximate to each linear array of LEDs to receive and redirect the light emitted by the LEDs. A flexible reflector extends between the first and second support structure. The reflector has at least one diffusedly reflective surface. The reflector is configurable to an operational configuration with the diffusedly reflective surface positioned to receive the light redirected by the first and second longitudinal lenses. The reflector is configurable to a transportable configuration with at least a portion of the reflector wrapped around at least one of the first and second support structures.

An electric working machine according to one aspect of the present disclosure includes a motor, a driving mechanism, a housing, a grip, a first light emitter, and a light guide. The first light emitter emits light. The light guide has a ring-shape. The light guide is extending along an outer circumference of the housing. The light guide includes a light entering surface receiving the light emitted from the first light emitter. While propagating the light entered from the light entering surface in the light guide, the light guide radiates the light from a surface of the light guide.
