A lighting arrangement (100), comprising an optical element (110) in the form of a rod comprising a translucent material, wherein the optical element elongates along a first axis. A. The lighting arrangement further comprises at least one array (120) of light emitting diodes (130). LEDs, wherein each array of the at least one array of LEDs comprises at least two adjacently arranged rows (150) of LEDs. Each row of LEDs comprises sequentially arranged LEDs configured to emit light being of the same color in the row, the color being different to a color of the light configured to be emitted by the LEDs of any of the other rows. Each array of the at least one array of LEDs is arranged on an outer surface (160) of the optical element and arranged in a spiral shape around the optical element.

A layered simulated flame mechanism for use in an electric fireplace, the layered simulated flame mechanism comprising: two or more video display surfaces, spaced apart, and oriented in layers relative to each other by one or more of (i) different elevations, (ii) different orientations in a horizontal plane, or (iii) different orientations in a vertical plane, one or more dedicated video processors transmitting flame videos onto each of the display surfaces, generating a simulated flame on each of the video display surfaces, wherein the spacing and orientation of the two or more video display surfaces relative to each other creates a three-dimensional flame appearance.

A lighting device disclosed in an embodiment of this invention includes a reflective layer, a resin layer disposed on the reflective layer, a substrate disposed on the resin layer and including an electrode layer, a plurality of light emitting devices disposed between the resin layer and the substrate, and a light blocking layer disposed on the substrate, the electrode layer may include a first pattern region disposed adjacent to the light emitting device and a second pattern region disposed outside the first pattern region and having a pattern different in size from the first pattern region, and the light blocking pattern region may overlap in a vertical direction with the first pattern region.

A light bulb having an electro-optical device for displaying a dynamically moving fire flame. The electro-optical device can include a housing, wherein the housing is at least partially transparent and a plurality of photoemitters arranged and disposed within the housing in a grid or matrix configuration. In addition, the electro-optical device can include a controller in communication with the plurality of photoemitters, wherein the controller is configured to transmit a control signal to at least a first portion of the photoemitters in order to cause the display of the fire flame. Here, each of the plurality of photoemitters may include at least one layer of phosphor, wherein the at least one layer of phosphor is disposed within the housing. In addition, the plurality of photoemitters can each include at least one semiconductor photoemitter such as a light emitting diode (LED).
