A lamp structure contains: a lampshade, a transmission cap, and an illumination element. The lampshade is tubular and includes a first orifice and a second orifice which are defined on two ends of the lampshade respectively. The lampshade is opaque and includes a reflective face formed on an inner wall thereof. The transmission cap is tubular and is accommodated in the lampshade, and a gap is defined between the transmission cap and the reflective face. The illumination element is defined between the transmission cap and the reflective face of the lampshade. One part of lights penetrates through the transmission cap from the illumination element, another lights emit out of a front side of the lamp structure via the reflective face, the transmission cap and the first orifice, and the other lights illuminate out of a rear side of the lamp structure via the second orifice.

A portion of the light from the light emitted by a light-emitting element enters the entrance region, then, is reflected by the first reflective surface on the same side as this entrance region with respect to the optical axis serving as a boundary, and is caused to exit from the second reflective surface on this same side. Another portion of the light enters the entrance region, is reflected by the second reflective surface and the third reflective surface, in this order, on the same side as this entrance region with respect to the optical axis serving as the boundary, is then caused to exit from the connection surface on this same side, re-enters from the first reflective surface or the connection surface on the opposite side with respect to the optical axis, and is then caused to exit from the second reflective surface on this opposite side.

Various embodiments of the present invention provide a light emitting diode (LED) lighting fixture and methods of installing the same. In various embodiments, an LED lighting fixture may comprise: at least one socket comprising a socket opening; at least one LED positioned substantially within the socket opening; at least one shield member positioned adjacent the at least one socket such that the shield substantially encloses the socket opening; at least one decorative light shade; at least one cover comprising a neck portion having an internal surface, the internal surface defining a cover opening. The cover opening is configured to receive there-through at least a portion of a socket and substantially engage the socket. At least a portion of the cover is configured to substantially engage the decorative light shade. Also, at least a portion of the cover is configured to substantially enclose the LED and shield.

In order to be able to realistically display and imitate the presence of humans and/or animals in a building with simple, inexpensive means, it is provided that the intensity of the radiated light of at least one group of adjacent light sources is reduced relative to the intensity of the radiated light from light sources of the arrangement outside of the at least one group in order to imitate a shadow on a wall illuminated by the security device and further light sources are added to at least one group and/or light sources of the at least one group are removed from the same and the intensity of the radiated light of an added light source is reduced and the intensity of a remote light source is increased in order to imitate a movement of the shadow.

A strengthened glass cover for a light fixture includes a glass core layer, a first glass cladding layer fused to a first surface of the glass core layer, and a second glass cladding layer fused to a second surface of the glass core layer. A coefficient of thermal expansion (CTE) of the glass core layer is greater than a CTE of each of the first glass cladding layer and the second glass cladding layer, whereby the glass core layer is in tension and each of the first glass cladding layer and the second glass cladding layer is in compression. A light fixture includes a housing and the cover coupled to the housing.

A light emitting device (LED-Filament) comprises: a light-transmissive substrate; at least one blue LED chip mounted on the light-transmissive substrate, for instance mounted on a face thereof; and a photoluminescence material at least partially covering the at least one blue LED chip. The photoluminescence material comprises narrow-band red phosphor particles that generates light with a peak emission wavelength in a range of 600 nm to 640 nm and a full width at half maximum emission intensity of 50 nm to 60 nm. The light emitting device is characterized by CRI Ra greater than or equal to about 90. The narrow-band red phosphor particles can comprise at least one Group IIA/IIB selenide sulfide-based phosphor material such as for example CaSe.sub.1-x S.sub.x:Eu (CSS phosphor). The LED-filament can be incorporated in a lamp, with a yellow to green-emitting phosphor that generates light with a peak emission wavelength in a range of 520 nm to 570 nm, to provide light with a color temperature in a range of 1500 K to 4000 K or 1500 K to 6500 K and a General Color Rendering Index (CRI Ra) greater than or equal to about 90 and a CRI R9 greater than or equal to about 50.

An LED tube lamp includes a lamp tube, two end caps, an LED light strip, a power supply, and a reflective film. At least a portion of an inner surface of the lamp tube is formed with a rough surface, and the roughness of the rough surface is higher than that of the outer surface. Each of the two end caps is coupled to a respective end of the lamp tube by a gel. The LED light strip is disposed on an inner surface of the lamp tube with a plurality of LED light sources mounted on the LED light strip. The power supply is disposed at one or two of the end caps. The power supply is electrically connected to the plurality of LED light sources. The reflective film is disposed on the inner surface of the lamp tube.
