What is a lamp with a cold beam?

Caching beam lamp is a type of light that is designed to redirect its heat from the light beam. These lamps can still generate as much waste heat as conventional lamps, but their designs allow them to bleed heat on the sides or by bulb. This is usually achieved by a dichroic reflector that can reflect visible light while allowing to pass through infrared light. This may result in a much cooler light beam that can be useful in applications in which the heat sensitive object must be illuminated.

Dichroic reflector works by reflecting one particular spectrum of light while allowing all other light to go through. Dichroic reflectors and filters are useful in different applications, from theater works and 3D films to jewelry. In the case of cold beam lights, they are designed to reflect the visible spectrum of light over the front of the lamp, while the invisible infrared light passes and leaves the rear of the lamp.

timely use for lamps of cold beam was in projectors. Since the light source in the sliding projector is usually very close to the sliding slip, the use of a cold beam can prevent the potential of damage to the slide. Most halogen lamps in many different applications now use dichroic technology. Lamps with this design can be found in residential and commercial applications. The light of the cold beam lamp is usually marked with cooler and whiter than the light of other lamps.

While lamps with a cold beam can be useful for situations where the heat sensitive object must be illuminated, they can be dangerous in some other uses. Many recessed luminaires may be a risk of fire when used with a lamp of a cold beam. This is because the infrared thermal energy that passes through the back of the lamp can be captured within the niche, to create high temperatures and pose a potential risk of fire. Although most haloguen lamps useDichroic reflectors, special bulbs for applications such as these are usually available as well.

alternative to the lamines of cold rays in applications for which they can be dangerous is the diode (LED) lamp emitting light. These bulbs can produce light that is even cooler than a halogen lamp and can be safely installed in recessed light applications. LED lamps are also usually available in different samples that correspond to different bulbs, including halogen lamps. They are usually much more expensive than their bulbs, but they can take much longer.
