Protecting competition in markets is considered a central task of the state within market economies because competition is essential for promoting innovation, efficiency, and consumer choice. When competition is allowed to thrive, it drives businesses to constantly improve their products and services in order to attract customers, leading to better quality and lower prices for consumers. Additionally, competition helps prevent the concentration of economic power in the hands of a few dominant firms, which can lead to market distortions and reduced consumer welfare. Therefore, the state plays a crucial role in enforcing antitrust laws and regulations to ensure fair competition and prevent the abuse of market power. **

Point-shaped light sources are typically used in applications where a concentrated beam of light is needed, such as flashlights, spotlights, or streetlights. On the other hand, area-shaped light sources are used in applications where a more diffused and widespread illumination is required, such as in ceiling lights, wall sconces, or ambient lighting fixtures.
