Description
上記目的を達成するために、本発明に係る照明装置は、
光源と前記光源を収納する第１筐体とを有する光源ユニットと、
前記光源を点灯させる点灯回路基板と前記点灯回路基板を収納する第２筐体とを有する点灯回路ユニットと、
長尺であり剛性が予め設定された基準剛性以上であり、長手方向の一端部が前記第１筐体に連結され長手方向の他端部が前記第２筐体に連結された連結部材と、を備え、
前記連結部材は、前記第１筐体に連結された前記一端部を基点として旋回自在であり、
前記第２筐体は、前記連結部材の他端部に回転自在に取り付けられている。
In order to achieve the above object, a lighting device according to the present invention includes:
A light source unit having a light source and a first housing for housing the light source;
A lighting circuit unit having a lighting circuit board for lighting the light source and a second housing for housing the lighting circuit board;
A connecting member that is long and has a rigidity equal to or higher than a preset reference rigidity, one end in the longitudinal direction connected to the first housing, and the other end in the longitudinal direction connected to the second housing; With
The connecting member, Ri pivotable der the end portion connected to the first housing as the base point,
The second casing is rotatably attached to the other end of the connecting member .
本発明によれば、連結部材が、長尺であり長手方向の一端部が第１筐体に連結され長手方向の他端部が第２筐体に連結されており、連結部材が、その一端部を基点として旋回自在である。また、第２筐体が、連結部材の他端部に回転自在に取り付けられている。これにより、第１筐体を造営材に設けられた貫通孔の内側に設置した状態で、連結部材をその一端部を基点として旋回させるとともに、第２筐体を回転させることにより、点灯回路ユニットの位置を変更することができる。従って、点灯回路ユニットのために確保すべきスペースの自由度が高くなるので、その分、照明装置の設置場所の自由度が高まる。また、連結部材が予め設定された基準剛性以上の剛性を有することにより、第１筐体と第２筐体との間の距離が連結部材の長さで定まる規定の距離以上に維持される。従って、連結部材の長さを、光源と点灯回路基板との間の距離が光源で発生した熱が点灯回路基板に影響しない長さ以上となるように設定することにより、光源で発生した熱の点灯回路基板への影響を抑制できる。 According to the present invention, the connecting member is long, one end portion in the longitudinal direction is connected to the first housing, the other end portion in the longitudinal direction is connected to the second housing, and the connecting member has one end thereof. It can turn freely from the base. Moreover, the 2nd housing | casing is rotatably attached to the other end part of the connection member. As a result, the lighting circuit unit is rotated by rotating the second casing while rotating the connecting member with the one end as a base point in a state where the first casing is installed inside the through hole provided in the construction material. The position of can be changed. Accordingly, the degree of freedom of the space to be secured for the lighting circuit unit is increased, and accordingly, the degree of freedom of the installation location of the lighting device is increased. In addition, since the connecting member has a rigidity equal to or higher than a preset reference rigidity, the distance between the first housing and the second housing is maintained at a predetermined distance or more determined by the length of the connecting member. Therefore, by setting the length of the connecting member so that the distance between the light source and the lighting circuit board is not less than the length that does not affect the lighting circuit board, the heat generated by the light source can be reduced. The influence on the lighting circuit board can be suppressed.
