Lighting is a thoughtful application of lighting source to get visibility and accomplish a specific task during the darkness by providing desirable illumination. In present context, there are numerous light sources and lighting technologies. But, with the advancement of technologies, traditional lighting technique is being gradually replaced by efficient lighting system with specific purpose and application. This study presents current status of lighting technologies, applications, challenges, policies and impacts in Nepalese scenario. This study also presents some statistic outcome, drawn from a survey of 250 sample size including different five target group. From this study, it is found that the people and government are moving toward the efficient and clean lighting technologies from traditional one. These activities on the implementation of efficient lighting technologies help the people in different sectors, such as education, health, security, economy etc., and in the improvement of living standard.

In 2015, the ecological, economic and social necessity of increasing energy efficiency contributed to street lighting renewal in the Spanish municipality of Casarabonela. Considering fixed operating and maintenance costs, it was a significant, long term investment with high impact for the community. Technicians chose LED light sources after studying technical and economic proposals submitted. Measurements of light levels, energy consumption and costs were carried out before and after the renovation. Once the chosen proposal was implemented, follow up surveys from technicians, maintenance workers and final users were collected. This case study aims to describe steps taken in the process of luminaires replacement. It has been estimated savings, expected and actual together with the return period on investment. This case may well serve as a prototype for a subsequent multiple case study which aims to validate a list of indicators obtained in a previous research.

The term “window” in architecture usually stands for an opening in a wall or roof for penetration of natural light, sunrays and fresh air in premises. Recently, the requirement of contact with environment is added to this condition. It is especially relevant for residential buildings where rooms are considered residential if they have windows. The energy consumption of a building depends on sizes, form and location of windows. In winter, windows cause huge heat losses, in summer, on the other hand, large heat enters a building via the windows and is required to be removed by means of air conditioning. Moreover, windows are used for penetration of natural light in premises, which assists in saving of large amounts of power for artificial illumination. This article discusses partial solving the problem of the energy efficiency of residential buildings by determining the most efficient area of windows in terms of energy spending for compensation of heat losses via windows in winter, elimination of heat penetration through them in summer and energy losses for artificial lighting throughout the year. The analysis of the results of calculation of power consumption for residential premises in conditions of monsoon climate of the Russian Far East and Northern areas of China (PRC) is provided.

The progress in industrial and technological areas, which started with the Industrial Revolution, has deteriorated the ecological balance and depleted the natural resources. Sustainability, which initially seemed as a solution within this concept, became an important part of Interior Architecture as in disciplines related to design. The lighting systems of the offices that are the secondary living areas should be evaluated in terms of sustainability as well.
In this paper, the energy savings and loss of the artificial office lighting systems has been calculated according to the ASHRAE/IES standard 90.1Ц20078?1 which are included in the Leadership in Energy and Environmental Design (LEED) certificateТs lighting criteria [1]. The wattage of the artificial lighting systems has been calculated while the systems were in use. The results of these measurements have been compared with lighting wattage and thus the lighting energy savings and loss have been configured. The office has been comparatively analyzed according to LEED criteria.

An integrated sensor based daylight responsive light controller has been designed and developed. The developed cost-effective light controller performs on logical decision derived from output of integrated sensor circuit comprising of daylight sensor and occupancy sensor. The performance analysis has also been carried out to understand the actual operating condition of the system using different sensors to control lamp circuits in small indoor lighting applications. The sensitivity levels of the photo sensor (i.e. a Light Dependent Resistor or LDR) and the occupancy sensor (i.e. a Passive Infrared Sensor or PIR) circuits can be adjusted through in-built tuning facility in developed circuit after experimental measurement of the response characteristics of the both sensors. By monitoring the indoor lighting system with the developed controller, it is possible to reduce the usage of electrical energy during the absence of occupant in any room. It is also possible to vary lamp output according to the seasonal variation in daylight level by selecting different reference voltage level and to use minimum electrical energy by utilizing the available daylight. It is a low cost solution due to the advantage of components and the sensors in the market at low cost.

The article analyses the operational characteristics of 10W LED lamps with T8 bulb manufactured by ASD (Russia), Smartbuy (Taiwan), and VOLPE (PRC) and 18W FL with T8 bulb manufactured by PHILIPS (Poland) including the dependence of these lamps on the supply voltage. The results of measurements show that: a) the period of stabilisation of electric parameters and luminous flux of LED lamps does not cause discomfort of illumination unlike the said FL, the luminous flux of which at the moment of switching on is 70 % of the nominal value, which is reached after 13 minutes; b) with nominal voltage of supply network, the value of luminous flux of 10W ASD LED-T8R-STD LED lamp (Russia) is 6 % less than the declared one, and that of Smartbuy SBL-T8-10-64K-A (Taiwan) and VOLPE LED-T8-10W/DW/G13/FR/FIX/N (PRC) is even less; c) the general colour rendering index of all studied LED lamps is less than the declared one (72 instead of 80); d) the flicker index of all studied LED lamps does not exceed the declared value of 5 %; e) the characteristics of LED lamps almost do not depend on changes of the supply voltage within the range of ±10 %.
The recommendations regarding the application of the studied LED lamps are given.

Contemporary light engineering is ready to make its contribution in the development of new, automated and (in the nearest future) fully computerised production facilities based on application of artificial irradiation for technological purposes. It is referred to cultivation of plants using the photo-culture technology in multi-layer phytoinstallations with spectral characteristics and level of irradiation taking the species and tasks of cultivation into account. The major type of plants for these installations is lettuce cultures, consumption of which in Russia significantly lags behind the recommended values, especially during winter. The article reviews major specifications of LED-based irradiation devices and lighting systems based on them, used for cultivation of lettuce in automated multi-layer phytoinstallations in photo-culture environment. An example of such phytonstallations is the automatic research installation developed in S.I. Vavilov VNISI, which has no parallel in Russia. A principal distinction of the irradiation devices used in this installation is application of multi-component LED compositions based on white and colour elements allowing us to vary spectral characteristics in the PAR region within a wide range. Generally, the installation is notable for contemporary hardware and availability of computer control.
