Description

Lighting device
Technical field
The present invention relates to lighting device, this lighting device bends to a plurality of stages with installing component, makes to point to a plurality of different directions from the light that is installed in a plurality of light-emitting device modules on the installing component.
Background technology
For example in the lighting device that patent documentation 1 is put down in writing, be provided with: light-emitting device module with light-emitting component, be used to install the installing component of a plurality of light-emitting device modules, and the support component that is used to support installing component, installing component bends to a plurality of stages, makes to point to a plurality of different directions from the light that is installed in a plurality of light-emitting device modules on the installing component.
And in this lighting device, a light-emitting device module is made of a plurality of white light-emitting diodes and a planographic substrate.And, five light-emitting device modules are installed with respect to the installing component that bends to five stages.And the installing component that five light-emitting device modules are installed is by supporting units support.Installing component bends to five stages on left and right directions.
Therefore, bending to along left and right directions in the installing component in five stages, be installed in the key light axis and the formed angle maximum of horizontal plane of the light-emitting device module on the installing component middle body, the key light axis and the formed angle of horizontal plane that are installed in the light-emitting device module on the part of installing component right side are second largest, are installed in installing component more the key light axis and the formed angle minimum of horizontal plane of the light-emitting device module on the part of right side.
And, bending to along left and right directions in the installing component in five stages, be installed in the key light axis and the horizontal plane shape angulation maximum of the light-emitting device module on the installing component middle body, the key light axis and the formed angle of horizontal plane that are installed in the light-emitting device module on the installing component left part are second largest, are installed in installing component more the key light axis and the formed angle minimum of horizontal plane of the light-emitting device module on the left part.
As a result, point to five directions, to the left and right directions wide-angle irradiation of lighting device from the light that is installed in five light-emitting device modules on the installing component.
Therefore, for example be provided with under the situation of above-mentioned lighting device in the roadside, the light of self-emission device module is to the travel direction wide-angle irradiation of road in the future.
, in the lighting device that patent documentation 1 is put down in writing, installing component is bent upwards at right and left, but not crooked on fore-and-aft direction.
In this lighting device, because installing component is bent upwards at right and left, thereby be installed in the key light axis of the right side of installing component or the light-emitting device module on the left part and the formed angle of horizontal plane less than key light axis that is installed in the light-emitting device module on the installing component middle body and the formed angle of horizontal plane, yet, thereby be installed in the light-emitting device module on the installing component middle body and be positioned at wherein the key light axis and the key light axis almost parallel that is positioned at the white light-emitting diode of bottom side of the white light-emitting diode of front because installing component is not crooked on fore-and-aft direction.
As a result, can be from the light of light-emitting device module to the left and right directions wide-angle irradiation of lighting device, however can not be to the fore-and-aft direction wide-angle irradiation of lighting device.
Therefore, when illuminating near the position of lighting device in will be, just the position away from lighting device can not be illuminated, on the other hand the front side of lighting device, when illuminating away from the position of lighting device in will be, just the position near lighting device can not be illuminated the front side of lighting device.
In detail, for example be arranged under the situation in roadside at above-mentioned lighting device, the light of self-emission device module is to the lane direction wide-angle irradiation of road in the future, as a result, can only will illuminate near the road surface of the position of lighting device or away from the arbitrary road surface in the road surface of the position of lighting device in the lane direction of road.
