If each light-emitting component 72 in the light source portion 7 is lit a lamp, then can produce heat from each light-emitting component 72.The heat that each light-emitting component 72 produces mainly is to conduct to as the installing plate 73 of radiating component from substrate 71 rear side and be released.In the case, installing plate 73 is to be positioned at than installation component 1 position and the mode exposed to the outside and setting more in the outer part, and therefore, extraneous gas plays a role easily and this installing plate 73 is cooled off, thus heat radiation with producing effect.
As mentioned above, according to present embodiment, installation component 1 side and light source portion body 2 sides are formed be electrically connected, thereby can guarantee security.In addition, can provide following lighting device, the electric wire of this lighting device can unexpectedly not expose, and can successfully carry out distribution and process.
Moreover, in said embodiment, used hinge structure as locking combining unit, also the light source portion body can be installed on the front surface side of installation component in mode to be opened/closed.And, for example also can anchor clamps be set on two limits in opposite directions of outside framework, maybe can make the light source portion body break away from installation component thereby the light source portion body can be installed on installation component.In the case, the front surface side of installation component also can open and close by the light source portion body.So, lock combining unit and can use various formations, be not defined in especially specific formation.
The utility model is not limited to the formation of described embodiment, in the scope of the aim that does not break away from utility model, can carry out various distortion.In addition, described embodiment is the embodiment that is prompted as an example, and the intention that limits of the scope of unmatchful utility model.
In said embodiment, following situation is illustrated, this situation refers to use the LGP that forms the quadrangle shape, and light-emitting area forms roughly quadrangle shape, but such as also LGP being formed hexagon or octagon etc., dispose accordingly light-emitting component with described each bar limit, and front baffle is formed toroidal, the rounded shape of the light-emitting area ground of LGP is exposed, thereby form the light-emitting area of toroidal.
In addition, described embodiment is suitable for the lighting device that throws light on LGP, but is not limited to this.Also applicable to the lighting device that does not use LGP.And, be suitable for using the light-emitting components such as LED as the situation of light source, but there is no special restriction.Also be suitable for using fluorescent lamp etc. as the situation of light-emitting component.
