Summary
Energy efficient Compact Fluorescent Lamps (CFLs) emit ultraviolet (UV) radiation, unlike Light Emitting Diodes (LEDs). This review compares UV emissions from energy-saving bulbs and their effects on skin, especially for those with light sensitivity.
Area of Science:
- Photobiology
- Dermatology
- Lighting Technology
Background:
- Energy-efficient lighting is increasingly adopted globally.
- Compact Fluorescent Lamps (CFLs) are common but emit ultraviolet (UV) radiation.
- Light Emitting Diodes (LEDs) offer an alternative with minimal UV output.
Purpose of the Study:
- To review available energy-efficient light sources.
- To compare UV emission levels of different lighting technologies.
- To assess the effects of UV radiation from these sources on skin.
Main Methods:
- Literature review of energy-efficient lighting technologies.
- Comparison of reported UV radiation levels.
- Analysis of dermatological effects on individuals with and without photodermatoses.
Main Results:
- CFLs exhibit notable UV emissions.
- LEDs demonstrate significantly lower UV emissions compared to CFLs.
- Potential risks associated with UV exposure from lighting are discussed for sensitive skin.
Conclusions:
- LEDs represent a safer alternative to CFLs regarding UV radiation exposure.
- Individuals with photodermatoses may be more susceptible to UV effects from lighting.
- Further research into long-term effects and specific UV outputs is warranted.

02:39Emission Spectra
65.1K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

01:20Atomic Emission Spectroscopy: Overview
3.0K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

5.6K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

1.6K
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules.

01:13Atomic Absorption Spectroscopy: Radiation and Light Sources
1.6K
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

01:24The Electromagnetic Spectrum
17.0K
Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...
