Heat lamps are devices that emit infrared radiation to provide warmth and comfort. They are commonly used in various settings, including homes, restaurants, and farms. These lamps can help keep food warm, provide heat for pets, or create a cozy atmosphere in outdoor spaces. Typically, heat lamps use incandescent bulbs or halogen bulbs to generate heat. They come in different designs, such as portable units or fixed installations. Heat lamps are often used in food service to keep dishes warm and in animal care to ensure the well-being of young or sick animals.
