The present invention relates to an illumination apparatus () comprising a light engine () and a first lampshade () for accommodating the light engine (), wherein the first lampshade () has a first expansion coefficient, wherein the illumination apparatus () further comprises a second lampshade () for accommodating the first lampshade (), wherein the second lampshade () has a second expansion coefficient smaller than the first expansion coefficient, and is configured such that the changes in size or shape of the first lampshade () can be restrained under a high temperature.

Illumination apparatus

Various embodiments may relate to a lamp holder of a lighting module, including a first housing and a second housing made from different materials, wherein the second housing includes a body part and an assembling part in thermal contact with each other, wherein the second housing is embedded integrally in the first housing and in thermal contact with the first housing, and the assembling part and the body part are installed together. In addition, various embodiments further relate to a method for manufacturing the lamp holder and an illuminating device having the lamp holder.

Lamp holder and manufacturing method thereof and illuminating device having the lamp holder

A lens for an illumination device, in a cross section, includes a bottom surface, and a first side surface and a second side surface which respectively extend inclinedly upwards from two sides of the bottom surface and converge. The bottom surface includes a supporting surface and an incident surface, the incident surface defining an accommodation cavity for accommodating a light source of the illumination device. The first side surface includes a first emergent surface and a first reflective surface, the second side surface includes a second emergent surface. A first part of light from the incident surface emerges from the first emergent surface, and a second part of light from the incident surface at least emerges from the second emergent surface after reflected by the first reflective surface, such that the emergent light is distributed at an angle of 360&#xb0;.

Lens and an illumination device having the lens

A lens may include a light incident surface, a first light emergent surface and side surfaces joining the light incident surface and the first light emergent surface. The light incident surface defines a space for accommodating light sources. The side surface includes at least one total-internal reflection surface and at least one second light emergent surface, a first part of light passing through the light incident surface is refracted by the first light emergent surface and emerges to generate first emergent light, a second part of light passing through the light incident surface is reflected by the total-internal reflection surfaces to the first light emergent surface and is refracted by the first light emergent surface and emerges to generate second light emergent light, and a third part of light passing through the light incident surface is refracted by the second light emergent surfaces and emerges to generate third emergent light.

Lens for LED illumination

Various embodiments may relate to a lens for a lighting assembly. The lens includes a bottom surface, a top surface and a side surface joining the bottom surface and the top surface.
