The present invention relates to a lighting device for plant cultivation, and more specifically, to a lighting device for plant cultivation on which a substrate on which a plurality of LEDs or discharge tubes (fluorescent lights) are installed can be easily installed on a ceiling panel with just one installation process of the lighting panel. .

In general, technology using LED lighting as a light source for plant cultivation has been widely used in plant cultivation factories in recent years.

Typically, plants grow by chloroplasts synthesizing carbohydrates such as starch from carbon dioxide gas and water using the power of sunlight. Photosynthesis, which converts light energy into chemical energy in plants, is an important part of plant growth.

Therefore, conventionally, many types of lighting devices for plant cultivation that irradiate light necessary for photosynthesis to plants have been known and used so that plants can be grown in indoor spaces where sunlight does not enter.

Accordingly, first of all, as an example of a conventional lighting device for plant cultivation, “multipurpose lighting device for plant cultivation” (hereinafter referred to as “conventional lighting device for plant cultivation”) of Republic of Korea Patent Registration No. 1313913 is known.

A conventional plant cultivation lighting device includes a body, a heating part provided below the body to emit heat to the plants, and a light emitting part provided below the heating part to emit light to the plants.
