“…As is denoted the lowest and highest UV emission were recorded in 45 ∘ and 90 ∘ angle, respectively. The similar results reported by Roisin et al and Safari et al concluded that CFLs radiate more horizontally (90 ∘ ) at the expense of the vertical intensity (0 ∘ ) [13,21].…”

Introduction.Replacing incandescent lamps with compact fluorescent lamps (CFLs), which are three to six times more efficient, is one of the easiest methods to achieve energy efficiency. The present study aimed to evaluate relationships between UV emissions radiated and illuminance CFLs.Material and Methods. This pilot study was conducted on 16 single envelope CFLs. The illuminance and UV irradiance of various types of CFLs are measured on a three-meter long optical bench, using a calibrated lux meter and UV meter, and measurement was done in 10, 25, 50, 100, 150, and 200 cm, in three angles, including 0°, 45°, and 90°, at the ages of 0, 100, and 2000 hours. Result. UVC irradiance was not observed at the distance of 10 cm in all of lamps. The lowest value of UVB irradiance was recorded in Pars Khazar lamp, while the highest value was recorded in Etehad lamps. UVR values measured at different times showed negligible differences; the highest asset value was detected in zero times. One way ANOVA indicated that relationships between UVA irradiance and illuminance were significant (P<0.05).Conclusion. UVB irradiance in most of the lamp in 10 and 25 cm was more than occupational exposure and UVA except for the fact that Pars Khazar 60 watts and Nama Noor 60 watts were less than occupational exposure.

“…In the present research, measurements of the spectral power distribution, absolute irradiance and illuminance to determine various parameters such as ultra violet irradiance (UVA), ratio of UVA irradiance to electrical power (h) and ratio of UVA power to luminous flux (K), for two groups of CFLs are studied to dedicate their performance and accompanied standard uncertainties are evaluated. UVA portion will be only concerned and the ratio of UV power to luminous flux is considered to be equal to the ratio of UV irradiance to illuminance [12,17].…”

“…This UV radiation then interacts with the chemicals on the inside of the bulb to generate light. Ideally, conversion of UV to visible light should be 100%; however, due to the defect in phosphor it contains trace amount of UV radiation [7][8][9][10][11][12]. To emphasis on use of energy saver CFLs, it is necessary to analyze the effect of radiation especially UV radiation on human health.…”

Abstract. During recent years, white compact fluorescent lamps (WCFLs) have played a key role in energy efficient campaigns worldwide. As the use of WCFLs becomes increasingly widespread so also increases the concerns relating to their mercury content and the associated hazards. While the risk associated with individual WCFLs is generally concerned negligible, the cumulative impact of millions of WCFLs does however becomes a more significant issue and could represent a potential risk to the environment. The present study aimed to focus on the most useable lamps in the Egyptian markets; white compact fluorescent lamps (WCFLs) and to evaluate relationships between UV emissions radiated and illuminance compact fluorescent lamps (WCFLs). Various parameters such as ultra violet irradiance (UVA), ratio of UVA irradiance to electrical power (h) and ratio of UVA power to luminous flux (K), for two groups of CFLs are studied to dedicate their performance. A set up based on NIS-Spectroradiometer ocean optics HR 2000 has been used for measuring the spectral power distribution white WCFLs with different Egyptian market. Second set up for NIS-UVA silicon detector for absolute irradiance measurements and relative spectral power distribution based on Spectroradiometer are used. The absolute irradiance in W/m 2 in UVA region of the lamps and their accompanied standard uncertainty are evaluated. Third set up based on NIS Luxmeter are used for measuring illuminance for these lamps. For all two groups under study, K parameter remains less than the safe limit for human health. Elios 32 watt WCFLs have smaller ratio (h) than Tiger 26 watt WCFLs. So, we recommended using Elios 32 watt WCFLs than Tiger 26 watt WCFLs at short distance in table lamps or other application and the distance more than 0.5 m. Uncertainty model includes all parameters accompanied with the measurements are calculated.

“…Many studies from world health organization approve that the compact fluorescent light bulb (CFL) produce electromagnetic pollution. These unsafe radiate products directly from light and distributed in all our bedroom, meeting room, and offices [1,2,3,4] the nearer your seat to the bulbs the greater your electromagnetic exposure. The electromagnetic radiation generated is not the same amount of energy, as the bulb power increases the radiation increases too, as shown in Figure 1.…”

The purpose of this work is to present new technology in acquiring energy from the compact fluorescent lamp (CFL) and store it in a super-capacitor to operate the emergency exit lights. Many studies show energy-efficient light bulbs may emit harmful radiation. This type of lamp emits high levels of radiation, causing migraine headaches, fatigue, and other health problems. The proposed system is based on the magnetic near-field coupling between the flat wound induction coil and the compact fluorescent lamp. CFL bulbs emit excessive dirty energy, the most of this energy will energize the super-capacitor and then in emergency lighting batteries through DC/DC step-up converter. So the proposed electronic device show a new technology to harvest the radiation generated by the bulb and charging batteries and secondly reduce the electromagnetic radiation inside a home, offices, and protect our children from radiation. The primary objective of the device is to reduce electromagnetic pollution at home and offices and regenerate energy from harmful radiation. The results are satisfactory and advantages of using technology to recycle electromagnet radiation to charge a battery, use at a critical time like an emergency light system. Besides, we can use it for many other applications. This purpose of this working is an extension of work initially presented in 2017 Ninth International Conference on Advanced Computational Intelligence (ICACI).
