Introduction
To maintain constant development, technicians have invested enormous effort and time into the inventions of multiple technical equipment. One of the typical instances is the UVA blacklights. They aim at emitting ultraviolet radiation as opposed to visible light during the observation of fluorescence of objects. With their various benefits generated, they have been applied in the creations of leak detection lamps, excitation light sources and lasers. Correspondingly, they have provided a drastic driving force in diverse applications, in particular, scientific research, crime scene investigation and art industry. To optimise their effectiveness, users should take several factors into consideration in advance of any operation.
Advantages of UVA blacklights
Considering the advanced technology engaged in the design of the UVA blacklights, they are equipped with a great intensity. The highest intensity can even be achieved with only 15 seconds. Additionally, their lifetimes are effectively enhanced. On the grounds that the environment which has to undergo observation can vary from a laboratory to the natural rough ground, a high durability is a determining factor. Furthermore, with a rechargeable battery provided, they are able to support 150 minutes of continuous operation. And more remarkably, concerning the safety problem, the UVA blacklights serve as the first choice. Since they do not carry any mercury or hazardous materials, no special cleaning is expected upon an accidental breaking. Thanks to the above advantages, the UVA blacklights are widely adopted in plentiful fields.
Factors to be considered before adoption
- UV Light Needs
Given the difficulties in measuring the brightness of a UVA blacklight emitted which is completely visible, technicians can quantify the light energy with a unit of ‘watt’. 1 watt of energy is adequate to cover a 100 square ft area, hence, the average efficiency of the UV light is 10%. Consequently, technicians should measure the size of the scanning and estimate the amount of energy needed for an optimal performance.
- Wavelengths
On account of the extended wavelengths of the UVA blacklights, the significance of deciding a suitable wavelength with reference of the circumstances is surging. Despite that the majority of UVA blacklightsrequire a narrow range of ultraviolet radiation which is approximately around 350 nanometres (nm). And usually, the peak can be achieved with a wavelength of 365 nm. However, loads of factors can influence the choice of wavelengths. For instance, with the reason that a positive relationship exists between the prices and wavelengths, technicians should strike a balance for economical purpose. On top of that, a longer wavelength will diminish the number of fluorescent effects. Evidently, technicians should refer to the photometric test reports to seek for the maximum performance under different blacklight applications.
- UV Light Fixtures
Owing to the requirements under changing situations and technological improvement, technicians have created a variety of UV light fixtures which carry the identical UVA blacklights. For example, the UV LED strip lights can be divided into 1-inch intervals, that can be installed in some constrained areas, specifically, display cabinets, illustrating a great flexibility of applications. Another similar device is the rigid UV LED light bars, which are more suitable for more permanent and robust installations, while the UV LED wall washers are designed to cover a wall surface with UV light. As the lamps can be adjusted into different angles, they can create a comprehensive coverage onto the vertical surfaces. Another interchangeable device is the UV LED flood lights, that specialise for a vast area. They are also applicable in the outdoor environment. To illustrate, a number of environmentalists will utilise the UV lights to investigate the landscaping features. Accordingly, the numerous devices are able to cater for varying scenarios, contributing to a larger effectiveness.
Conclusion
With the inherent advantages concluded, the UVA blacklights have become one of the game changers in today’s technology. Still, it is vital to evaluate a number of aspects to further uplift their value, which include the UV light needs, wavelengths and UV light fixtures. Equivalently, technicians should adopt different UV wavelengths and intensities according to the purposes. As a consequence, UVA blacklights are apparently generating countless possibilities in plenty of fields and have become the most famous choice of lights for laboratory researches and investigation in the globe.
