A pointed arch lamp is a type of gas discharge lamp that uses a pointed arch in its construction. This type of lamp is often used in the illumination of historical or architectural buildings, but also in some modern lighting applications, for example, for artistic or aesthetic lighting effects. The name "pointed arch" refers to the lamp's shape, which resembles a pointed arch in architecture.
Features of a pointed arch lamp:
- Shape : The lamp has a characteristic pointed arch shape, which can be aesthetically appealing, especially in applications where the shape of the lamp plays a role, such as in decorative lighting.
- Gas discharge : Like many other gas discharge lamps, the ogival lamp operates using an electrical gas discharge process. Electricity is passed through a gas mixture (usually a combination of noble gases and mercury), resulting in the emission of light.
- Light Output : Arc lamps can produce a bright, clear light, similar to other gas discharge lamps, but with a unique aesthetic effect due to the shape.
Applications:
- Architectural Lighting : Pointed arch lamps are sometimes used in the lighting of historical or religious buildings, such as churches or cathedrals, to enhance the aesthetics of the architecture.
- Decorative Lighting : They can also be used for decorative purposes, for example in theatres or other events where lighting must be not only functional but also visually attractive.
- Outdoor Lighting : Some pointed arch lamps are used in gardens, parks or on street lighting to create a specific visual style.

In many cases, pointed arc lamps are a form of gas discharge lamp , such as mercury vapor lamps or high-pressure sodium lamps . However, they differ in shape and sometimes also in the type of gas mixture used. In some cases, they are designed to fit a specific architectural style .
In short, the pointed arch lamp is a unique and aesthetically interesting lighting option, mainly used in architectural and decorative applications, where the shape of the lamp is important in addition to the light output.
