What is Multifaceted Reflector
A Multifaceted Reflector (MR) is a type of lamp that provides directional light with a controlled light distribution. Originally designed for use in 35mm slide projectors, MR lamps have found widespread use in various applications such as retail, hospitality, residential, museum, and landscape lighting.
The key feature of an MR lamp is its integrated pressed glass reflector, which plays a crucial role in controlling the direction and spread of light emitted by the lamp. The reflector is composed of facets and covered by a reflective coating, allowing it to gather light from the filament and create a concentrated beam of light. MR lamps are available in different beam angles, ranging from narrow spotlights to wide flood lamps, providing flexibility in lighting design.

In terms of reflector coating, there are two common types used in MR lamps. Some lamps use an aluminum coating, which reflects both infrared and visible radiation forward. Others use a dichroic coating, which selectively filters out heat while allowing visible light to pass through. It is important to note that dichroic lamps should only be used in fixtures that can dissipate the heat generated.

Furthermore, MR lamps are known for their compact size, allowing for smaller and more discreet fixtures compared to traditional incandescent reflector bulbs. They are often incorporated into various types of luminaires, including track heads, recessed downlights, and landscape spotlights.
常見問題
哪種反射器最常見
圓形反射板是最常使用的反射板類型。由於它們可以在被攝者的眼睛中營造出美麗的圓形眼神光，因此特別受人像攝影青睞。另一方面，矩形反射板則更適合需要較大光量的較大型被攝體。
可以在家中選用哪些類型的反射器
家居環境中可使用多種反射器，包括通常呈寬扁平狀且為銀色的反光板。不過，攝影師有時也會選擇白色或金色的反光板。若您打算購買反光板，可在相機專賣店或網上找到可折疊反光板。此外，您亦可利用紙板與鋁箔紙自行製作反光板。
什麼顏色的反光板效果最好
銀色反光板在反射光線方面最為高效，非常適合低光環境。它們亦非常適合增強高光和對比度。然而，由於光線較為刺眼，應避免在陽光直射下使用銀色反光板。
不同顏色的反射器代表甚麼意思
每種顏色的反射器都有其特定用途，指引相當明確。白色反射器沿著白色標線設置，而黃色反射器則沿著黃色標線設置。紅色反射器用於提醒駕駛者正在單向匝道上逆向行駛或切勿進入。
What Two Types of Reflector Are Found Most Commonly in Theatrical Lighting Fixtures
The two most commonly found types of reflectors in theatrical lighting fixtures are the beam projector and the parabolic reflector. The beam projector is responsible for directing the light into nearly parallel beams, while the parabolic reflector is positioned in front of the lamp to reflect the light back to the parabolic reflector, effectively reducing spill.
