A lamp includes a mounting part configured to be capable of being mounted on a fixture, a lamp part, and two locking parts arranged on the lamp part. The mounting part includes two locking portions and each of the two locking portions have two first fastening elements arranged on two opposite ends thereof. Each of the locking part defines two slot assemblies corresponding to the first fastening elements. Each of the slot assemblies comprises a first slot, a second slot communicates with the first slot, and a third slot adjacent to the second slot. The lamp part is configured to be capable of moving between a first position where the first fastening elements are received in the first slots and a second position where the first fastening elements are received in the second slots while the ends of the first fastening elements enters the third slots.

The invention provides a lighting device (100) configured to provide lighting device light (101), the lighting device (100) comprising a solid state light source (10) configured to provide blue light (11) having a peak wavelength (λ.sub.PWL) selected from the range of 430-455 nm, a first luminescent material (210) configured to convert part of the blue light (11) into first luminescent material light (211) and a second luminescent material (220) configured to convert part of one or more of the blue light (11) and the first luminescent material light (211) into second luminescent material light (221), wherein the solid state light source (10), the first luminescent material (210), and the second luminescent material (220) are selected to provide at a first setting of the lighting device (100) white lighting device light (101) having a CRI of at least 90, a R.sub.9 value of at least 70, and a R.sub.50 value of at maximum 465 nm, wherein the R.sub.50 value is defined as a first wavelength (λ.sub.50) in a spectral distribution of the white lighting device light (101) at the first setting, wherein the first wavelength (λ.sub.50) is a wavelength closest to the peak wavelength (λ.sub.PWL) but at a longer wavelength than the peak wavelength (λ.sub.PWL) of the blue light (11) where the peak intensity (I.sub.50) is 50% of the intensity (I.sub.PWL) at the peak wavelength (λ.sub.PWL).

A luminaire control device for use with a municipal light pole. The device is plugged into a standard dimming receptacle and includes a universal power supply for converting AC power received in any of the common municipal distribution voltages to a uniform DC output usable by small electronic components of an accompanying control system. The universal power supply and control system are configured to fit within the form factor required by applicable standards. The control system includes program logic to control the luminaire by sending control signals via the dimming receptacle. These signals may be sent using one, two, or more control channels as defined by the standard, and may control a single luminaire or multiple luminaires via the different channels. The device may further include a wireless transceiver to facilitate remote access and control of the light, allowing a municipal light pole to be retrofitted as an IoT device.

Unique securement devices, usable for example as tripod feet, each feature a bistable spring band encapsulated in an outer skin with a set of optionally magnetic embedments discretely spaced along the band, and a coupler at one end for attachment to a tripod leg or other component. Unique ball and socket joints employ both a snap fit and a secondary retention mechanism to reliably secure together various components, including said securement devices and tripod legs. One joint includes an externally convex and internally concave ball coupler for optional mating with either a larger socket coupler or smaller ball. One joint includes a stabilization sleeve for angularly locking the ball and socket joint. An elongated support, usable as a tripod leg for example, features threaded connection ports usable to either directly mount threaded third-party componentry, or to receive a threaded ball coupler by which socket-equipped componentry can be indirectly attached.

An electric candle device that resembles a real was candle includes an outer shell with an uneven edge around the top of the outer shell. The device includes one or more light emitting elements positioned within a cavity inside the outer shell and that emit beams at a non-zero angle with respect to a longitudinal axis of the electric lighting device to provide illumination from within the cavity in an upward direction and reaching above the top surface after passing through the opening. An optical element is positioned to receive light from the one or more light emitting elements and to direct the received light toward the top surface. The optical element has a focal point to change one or both of a size and direction of the light received prior to projecting the light in the direction of the top surface.
