An LED (light emitting diode) includes a base, two spaced electrodes and a thermal conductivity layer. The base has a top surface. The two electrodes and the thermal conductivity layer are located on the top surface of the base. The thermal conductivity layer is attached to the top surface and located beside and between the electrodes. The two electrodes are electrically insulated from each other, and electrically insulated from the thermal conductivity layer. A light emitting chip is electrically connected to the two electrodes. The electrodes and the thermal conductivity layer are on different levels.

An exemplary lamp cover for covering a light source includes a connecting member, mounting members, first covering members, and a second covering member. The mounting members are integrally formed with the connecting member as a single piece. The first covering members are detachably mounted on the connecting member and alternated with the mounting members. The second covering member is capable of being mounted on the connecting member to replace one of the first covering members to change a shape of a light field of light emitted from the light source and through the lamp cover.

An illumination apparatus comprises at least two illumination apparatus modules arranged abreast and a connecting element. Each illumination apparatus module includes a cover, a case, and an elastic fastener. A supporting portion is mounted on the case supporting the cover. The sidewall of the case has a first hole, and the supporting portion has a second hole. The elastic fastener is mounted on the second hole. The supporting portion supports the cover and fixes the cover on the case. The connecting element passing through the first holes of the two adjacent sidewalls of two illumination apparatus modules fixes and connects the two illumination apparatus modules together. By the first holes and the connecting element corresponding to the first holes, each illumination apparatus module combines mutually. The elastic fastener fixes the cover and the case together.
