조명시뮬레이션 소프트웨어는 크게 조명기구의 광학설계를 위한 소프트웨어와 조명계획안의 예측 및 평가를 위한 소프트웨어로 구분할 수 있으며, 그 사용이 점차 증가하고 있다. 조명기구의 광학설계를 위한 시뮬레이션 소프트웨어로는 Photopia 2.0이 대표적이며, 조명계획안의 적합성을 판단하기 위한 시뮬레이션 소프트웨어는 Lumen-micro 2000, Relux 2006, Lightscape 3.2와 AGI 32 등이 있다. 이러한 시뮬레이션 소프트웨어는 측정값과 시뮬레이션 결과값, 그리고 소프트웨어별 시뮬레이션 결과값이 상이하게 나오는 경우가 발생한다. 따라서 본 연구는 임의의 조명기구 측정 배광데이터와 Photopia 2.0의 시뮬레이션 배광데이터를 비교하고, 공간의 규모, 배광데이터, 마감재등의 같은 조건하에 Lumen-micro 2000, Relux 2006, Lightscape 3.2와 AGI 32의 시뮬레이션 결과를 비교하여 차이점의 원인에 분석하고자 한다.

Lighting simulation is becoming increasingly more important as a method for design and evaluation. There is a wide range of packages that provide the accuracy and the usability in lighting simulation. Relux developed by Relux Informatik AG, Switzerland, Relux offers users innovative and high-performance light planning software with open interfaces and simultaneous access to the latest product data from luminaire and lamp manufacturers. The goals of this report is to explore some of the lighting simulation issues relating to Relux. It is hoped that it will provide some background information that will enable a designer and engineer to make some informed judgements on the potential of the current state-of-the-art in computer prediction of lighting in buildings and how this may be used to assist in building design.

Nighttime construction is being adopted by many state DOT's as a way to mitigate the impact of construction operations on the traveling public. Although a number of states have developed standard specifications for nighttime lighting, these standards are usually in the form of generic requirement statements that only specify minimum illuminance levels. The lighting standards do not include specific ways to achieve this illuminance level such as lighting arrangements and configurations for various work zone plans and construction operations. This leaves confusion between the traffic engineers and the contractors and does not guarantee consistency in those plans, thus affecting productivity and safety (lighting conditions account for 18% to 28% of work zone accidents). The main objective of this study is to utilize three dimensional animation and lighting analysis software to study and model lighting conditions of a construction site. This is expected to increase the safety and productivity of construction operations by achieving consistency in work zone lighting schemes. A computerized model was developed, called Nitelite. Various lighting schemes can be studied using the software to provide for typical applications including lighting fixture's locations, luminance, mounting height, tilt angle, and fixture type. The results from the developed software tool were validated through comparisons with previous research conducted using field measurements.

LED lighting is used as artificial lighting for plant growth because it has high light efficiency and can radiate light of various wavelengths. In this paper, we have developed new structure LED lighting module to improve the performance of LED lighting for plant growth and proposed a lighting control system that can be controlled wirelessly. The proposed LED lighting module was fabricated using optical lens applied to tunnel light and simulated using Relux program. Results of simulation, we confirmed that the light distribution and average illuminance of the proposed lighting were improved. LED lighting control system was developed to wirelessly control R, G, B, W LED lighting according to plant type and growing season. Therefore, it is expected to provide the optimal lighting environment for plant growth and contribute to the improvement of farm productivity and convenience.

Architecture design has need of daylight prediction to utilize daylight efficiently. But it is difficult to predict the exact value of available daylight in buildings. Using various lighting simulation software is not difficulty, but we can find different results under the same conditions. The purpose of this paper is to compare simulation values from various software such as Lumen-micro 2000, Lightscape 3.2, and Relux 2006. The same space and parameters of daylight(location of space and window, date, time, and skylight condition) are considered to conduct various simulation conditions.

DMX-512 protocol is a lighting protocol which can control the various lighting fixtures by linking as networks. Recently many lighting fixtures corresponding to DMX-512 have been manufactured. The software which makes LED Control of lighting fixtures easy and simple, is proposed in this paper. The complicated interface and production method were improved and each mode was divided for simple production and reducing confusion of operator. The producing effects were confirmed by simulation results.

Available daylight in inside offers comfortable view environment, and psychological and physical advantages to people in a room. Architecture design has need of daylight prediction for reflection efficiently daylight. But it is difficult to predict the illuminance values in daylight system. Using various lighting simulation software is easy and simple, but we can find different results under the same conditions. This study compares with illuminance values from simulation (Lightscape 3.2, RELUX 2007, RADIANCE 3.9) and Mock-up experiment with the same space and parameter of daylight (location of space and window, date, time and sky condition).

Recently, BIPV system which is good enough for maintenance and functions with the shading system is being used. However BIPV system with the shading system is different from existing PV module because of using flexible PV module. Prior to the application of the BIPV system, the clearness index was calculated by Erbs et al.(1982) and analyzed for the amount of electric power generation of sky irradiance with measured data. To predict electric lighting energy savings in daylit space, electric lighting power savings with amount of PV module electric power generation was compared by using Relux 2010 software in this study.

The objective of the work was to evaluate the impact of lighting energy to cooling and heating consumption in medium scale office building, when currently installed fluorescent lights were replaced with various LED lighting fixtures. This evaluation comes from an integrated approach combining the proper indoor lighting environment and the thermal aspects of cooling & heating consumption in office building. These simulations were performed by coupling an appropriate luminaire analysis for energy consumption and a dynamic thermal simulation software (TRNSYS). To analyze comparative study of effects on the heating, cooling loads, and energy consumption of an LED lamp application, 2 types of LED lamp with low light power watt(LPW) 24W and high LPW 7.5W and a fluorescent lights(FL) with 37W are used respectively. Integrated building energy consumption decreased up to 3.2% when fluorescent lamps were replaced with LEDs. Thus, the high LPW of LED(7.5W) replaced with the same number of FL shows an effective energy saving and cost- effective luminary.
