Description

Plasma Lighting Device and System Thereof The present disclosure is an invention relating to a lighting device and system that emits light using the plasma state of a gas. Plasma lighting is a lighting technology that emits light by using electromagnetic waves to transform the gas inside a lamp into a plasma state. This method has the advantage of accurately representing the colors of objects by emitting light with a continuous spectrum similar to sunlight. Accordingly, it is widely used in environments where accurate color representation is required, such as exhibition halls and studios. Furthermore, plasma lighting generally offers advantages in terms of excellent energy efficiency, long lifespan, fast ignition, stable light output, eco-friendly characteristics, and low maintenance costs, and is expanding its scope of application as a versatile lighting source for large buildings, sports stadiums, factories, and public facilities. There are difficulties in implementing the configuration of components such as reflectors. Meanwhile, driven by consumer demand for mobility and ease of installation regarding plasma lighting, attempts to miniaturize and lighten plasma lighting are increasing. However, plasma lighting requires the configuration of reflectors to direct light, and it is not easy to maintain light dispersion efficiency while reducing the size and shape of the reflectors. Consequently, there are challenges in miniaturizing and lightening plasma lighting. Figure 1 conceptually illustrates a conventional plasma lighting system. FIG. 2 conceptually illustrates a plasma lighting system according to one embodiment of the present disclosure. FIG. 3 is a perspective view of a plasma illumination according to one embodiment of the present disclosure. Figure 4 is a cross-sectional view in direction A of the plasma illumination according to Figure 3. Figures 5 and 6 conceptually illustrate the transmission of electromagnetic waves into the interior of a bulb. FIGS. 7 to 9 conceptually illustrate various positional relationships of a bulb and an antenna according to an embodiment of the present disclosure. FIGS. 10 to 13 conceptually illustrate the shape of a second reflective surface that reflects light emitted from a bulb at the point in time of FIG. 4. Embodiments of the present disclosure are described below with reference to the attached drawings so that those skilled in the art (hereinafter, those skilled in the art) can easily implement them. The embodiments presented in the present disclosure are provided to enable those skilled in the art to use or implement the contents of the present disclosure. Accordingly, various modifications to the embodiments of the present disclosure will be apparent to those skilled in the art.

The term “or” as used in this disclosure is intended to mean an implicit “or” rather than an exclusive “or.” That is, unless otherwise specified in this disclosure or its meaning is unclear from the context, “X uses A or B” should be understood to mean one of the natural implicit substitutions. For example, unless otherwise specified in this disclosure or its meaning is unclear from the context, “X uses A or B” may be interpreted as X using A, X using B, or X using both A and B. The term “at least one of A or B” as used in the present disclosure should be interpreted as referring to A, B, and combinations of A and B.
