What is Lighting Design Lumens (LDL)
Lighting design lumens(LDL) is the number of lumens emitted by a light source after it has been in operation for 2,000 hours. Lumens are a unit of luminous flux, which measures the overall light output of a luminous source. In lighting design, understanding the LDL is crucial for determining the expected light output and achieving the desired level of illumination in a space.
The LDL value takes into account various factors, including lumen depreciation and maintenance procedures. Lumen depreciation is the decrease in lumen output of a light source over time. Each lamp type has a unique lumen depreciation curve, which depicts the pattern of decreasing light output. By considering the initial rated output of lumens and the anticipated minimum rated output based on the re-lamping program, the lamp lumen depreciation factor (LLD) can be calculated. This factor is used in illumination calculations to relate the initial rated output to the anticipated minimum rated output, accounting for the expected decrease in light output due to factors such as lamp depreciation and maintenance procedures.

자주 묻는 질문
What Type of Lighting Is Best
Currently, the most durable lighting option available in the market is LED (light-emitting diode) bulbs. These bulbs are designed to fit standard light sockets and are highly energy-efficient. Despite having a lower wattage than incandescent bulbs, LED bulbs produce the same amount of light output while consuming less energy.
What Are the Three Elements of Lighting Design
The three primary components of lighting design for interiors include ambient lighting, task lighting, and accent lighting. These elements can be combined to enhance the aesthetics of your space.
럭스(Lux)와 루멘(Lumens) 중 어느 것이 더 적합한가요?
제곱미터당 1루멘은 1럭스와 동일합니다. 이 측정 단위를 통해 가시광선의 전체적인 “양'과 표면에 도달하는 조도의 강도를 수량화할 수 있습니다. 럭스는 광선의 인지적 밝기를 판별하는 효과적인 수단을 제공하므로 흔히 사용됩니다.
