Cold beam lamps redirect heat away from the light beam using a dichroic reflector, making them useful for illuminating heat-sensitive objects. However, they can be dangerous in some applications due to the potential fire hazard. LED lamps are a safer alternative and can produce cooler light. A cold beam lamp is a type of light […]
Daytime running lights (DRLs) are lights on vehicles that remain on during daylight hours to increase visibility. They are standard on many vehicles and required by law in some regions. Studies show they improve safety, but some have raised concerns about visibility for motorcyclists and potential hazards in substandard conditions. A daytime running light (DRL) […]
Safety lamps were developed for use in mines to provide lighting without causing explosions from flammable gases. Early lamps used flames, while modern lamps are electric and shielded to prevent sparking. They also act as alarms, with changes in the flame indicating dangerous gas levels. Today, miners use sensors for gas detection and wear safety […]
Mercury vapor lamps are HID lamps used for commercial and outdoor lighting. They produce bluish white light by introducing a mercury vapor electric current inside a sealed glass tube. They require a ballast and have an average life expectancy of over 24,000 hours. However, they have become less popular due to more efficient alternatives, and […]
The Davy lamp was invented in 1815 as a safe light source in coal mines. It also acted as a gas detector, but ironically led to more explosions. The Geordie lamp was introduced in 1816, causing debate over which was safer. Both had flaws, but the Davy lamp is still used today in modern coal […]
Carbide lamps burn acetylene and were originally designed for mining but are still used for caving and camping. They have two chambers connected with a valve that drips water into calcium carbide, generating acetylene that escapes through a nozzle. Safety risks include pressure buildup and overheating. The light produced is bright, white, and uniform, making […]
Carbide lamps burn acetylene gas and were originally designed for mining but are still used for caving and camping. They have two chambers connected by a valve that drips water into the lower chamber filled with calcium carbide, creating a chemical reaction that generates acetylene. Safety risks include pressure buildup and heat. The light produced […]
A modeling lamp, also known as a pilot light, is a light that illuminates when an electrical circuit is fed. It is used in various settings, including railway signaling and electronic devices, to indicate power or problems. Installing a modeling lamp is simple, and durable bulbs or LEDs are used to prevent unsafe conditions. A […]
A slit lamp exam is an eye exam that uses a low power microscope with a bright light source to examine the front and back of the eye. It can detect various eye disorders and is often used as part of a routine eye exam. A slit lamp exam is a type of eye exam. […]
Salt lamps are made from rock salt crystal and emit negative ions, which can improve air quality and provide relief from minor ailments. They can also generate a warm and relaxing light, and are believed to have various health benefits, including improving respiratory ailments, reducing stress and anxiety, and strengthening the immune system. A salt […]
Germicidal lamps use UV light to damage bacteria, viruses, and fungi, rendering them sterile or killing them. They are used in various settings and can be low or medium pressure. Precautions should be taken to avoid skin and eye damage, and lamps should be replaced annually. Combining control methods is most effective in preventing infection. […]
Choosing the right UV curing lamp can be challenging. It should have a long lifespan, dimming capabilities, and consistent exposure. A simple control device is necessary to prevent over-curing. An ultraviolet (UV) curing lamp is used by many manufacturers to cure or harden cured compounds, but finding the right UV curing lamp can be a […]
UV lamps emit ultraviolet light, which is used in terrariums for plants and reptiles, as a black light for entertainment, in tanning beds, and as a treatment tool for seasonal affective disorder. However, overexposure to UV rays can cause harm, including skin cancer. A UV lamp is a lamp specifically designed to emit light at […]
