A back panel for a lighting device includes a front panel holding portion, the front panel holding portion has a configuration capable of setting a size of a gap between a front panel held by the front panel holding portion and a panel main body to an arbitrary size.

Back panel for lighting device and lighting device

A lighting apparatus which provides an heat dissipation effect, high output and large light emitting area including: housing having rectangular cylindrical shape obtained by forming belt-like body including plurality of holding bodies in rectangular cylindrical shape and connecting end portions of belt-like body formed in rectangular cylindrical shape; and circuit board mounted on inner surface of the housing and including a light source. The circuit board includes: mounting portion mounted on inner surface of the housing and having a surface provided with the light source; and connecting portion which connects mounting portions adjacent to each other in peripheral direction of the housing and is bendable at a corner of adjacent inner surfaces of the housing, and rear surface of mounting portion contacts inner surface of the holding body. Therefore, it is possible to provide lighting apparatus which provides an excellent heat dissipation effect, high output and large light emitting area.

Lighting apparatus

Light emitting diode lamp

An optical unit is provided with an integral light condensing section and a light transmitting section. The light condensing section is in a shape of a parabolic body of rotation substantially widening from a proximal end toward a distal end with a concave section opening at a proximal end face to accommodate a light emitting element, a side circumferential face to reflect the light from the light emitting element inward and a distal end face to introduce the light from the light emitting element into the light transmitting section. The light transmitting section is a substantially cylindrical shape of a smaller diameter than the light condensing section, and comprises a proximal end face to introduce the light from the light condensing section, a side circumferential face to reflect the light introduced from the proximal end face inward and a distal end face to emit the light.
