Description

  The present invention relates to a light emitting device.

In recent years, there has been proposed a lighting device that converts electric power generated by a power generation device such as a solar power generation module or a wind power generation device provided by itself into light and emits the light (see Patent Documents 1 to 3).
According to such an illuminating device, since the electric power generated by itself is converted into light, it can be used as an independent illuminating device that does not require an external power source such as a commercial power source. In addition, in such a lighting device, power generation is performed using clean natural energy, so that it is expected to be an environmentally friendly future-type lighting device.

However, as is well known, at present, it is difficult to obtain a large amount of electric power by using solar power or wind. For this reason, it is difficult to emit light with sufficient luminance for a long time as a lighting device.
From now on, technological advancement will improve the power generation efficiency of power generation using sunlight and wind, but at present, the situation described above is preventing the spread of stand-alone lighting devices. Absent.
In addition, no proposal has been made to use light generated by electric power generated using clean natural energy such as solar power generation modules and wind power generators for light other than illumination light. Also hinders the spread of stand-alone lighting devices.

  The present invention has been made in view of the above-described problems, and an object thereof is to promote the spread of a light-emitting device that converts electric power generated by itself into light.

By adopting such a configuration, the phosphorescent paint or the fluorescent paint is applied to the windmill portion which is a moving object. For this reason, since it is more conspicuous with respect to a human eye, it becomes possible to call a human attention more.

Further, as the third means, in the first or second means, a configuration is adopted in which the light converting means is a display unit.
By adopting such a configuration, light generated by converting electric power can be used as display light for display instead of illumination light.

As a fourth means, in the first or second means, when the fluorescent paint is applied, a light emitting lamp that emits near ultraviolet rays toward the fluorescent paint is used as the light converting means. Is adopted.
By adopting such a configuration, electric power is converted into near ultraviolet rays, and the near ultraviolet rays are emitted toward the fluorescent paint. Since the fluorescent paint emits vivid colors when irradiated with ultraviolet rays, it is possible to attract more attention from humans.

As a fifth means, any one of the first to fourth means adopts a configuration in which a photovoltaic power generation module is provided as the power generation means.
By adopting such a configuration, it is possible to use the power generated in the solar power generation module.

  According to the light emitting device of the present invention, since the phosphorescent paint or fluorescent paint that is conspicuous to the human eye is applied, even if the power generation amount of the power generation means is small, it is possible to alert the human attention. . Therefore, it becomes possible to use a stand-alone light-emitting device other than the lighting device, for example, and to promote the spread of the light-emitting device that converts the power generated by itself into light.
