The Energy-saving and Environmental Protection of LED Tri-proof Luminaires Have Made Great Contributions to the Processing Industry
The three-proof lamps made of PC material are better material style, even if they are stepped on by foot, they will not break, and they are very durable. However, the transparency of this material is not as good as that of ABS lamps. The lamp made of ABS material is very brittle and crackable, but the transparency of this material is very good and bright. PMMA materials are cheaper, but less ...

Effect of window type, size and orientation on the total energy demand for a building in Indian climatic conditions
Windows in a building allow daylight to enter a building space but simultaneously they also result in heat gains and losses affecting energy balance. This requires an optimisation of window area from the point of view of total energy demand viz., for lighting and cooling/heating. This paper is devoted to this kind of study for Indian climatic conditions, which are characterised by six climatic ...

Energy Saving Lamps Don't Need to Use Liquid Mercury!
While mercury in various solid and liquid forms has to be used to make all fluorescent lights (including energy saving light bulbs - or CFLs) work properly, the mercury does not have to be used in its most dangerous liquid form. It can work just as well in a solid amalgam form combined with other elements. Using amalgam based CFLs is much safer, and environmentally friendlier. Megaman - ...

Light Emitting Theory of LED Tri-proof Luminaires
Luminescent diodes, commonly known as LEDs. The light emitting diode is just a tiny light bulb. But unlike the common incandescent bulbs, the LEDs have no filaments and are not particularly hot. They emit light only by the movement of electrons in semiconductor materials. Because the LED will burn out without filament, it will live longer. And the small plastic light bulb of the light emitting ...

En'lightening' energy use: the co-evolution of household lighting practices
Compact Fluorescent Light Bulbs (CFLs) are a well-developed, readily available technology that could deliver substantial energy savings in the residential sector. Due to this, lighting is usually a preferred target for household energy-saving campaigns and policies. However, the energy used to light homes continues to rise. In order to explore the reasons behind this increase, this paper examines ...

A Comparison between LED and HPS
For the longest time possible the lights in use have been HPS (High Pressure Sodium). These have been used in households and even commercial settings. They are not costly but they have a very short lifespan of about 2,000 hours. Some don’t seem to mind the lifespan of these bulbs because their price is not high so replacing them frequently does not seem like much of a cost. Doing a ...

Smart operation of air-conditioning (A/C) and lighting systems for national load management
In the countries of Arabian Peninsula, demand for electric power, primarily controlled by the air-conditioning (A/C) and generally peaking at 15:00 h, is currently growing well over 5% annually. Adaptations of smart operation of A/C and lighting systems in government and institutional buildings that commonly function between 07:00 h and 14:00 h has been evaluated as a technique for national load ...

The Cost-Benefit of Solar Street Light Installations
It’s a counter-intuitive thing, sometimes, to spend money in order to save it. We’re just like you; if we see an ad on television that promises you’ll save more if you spend more, our inner skeptic kicks in and we start to wonder if we need to spend money in the first place. It’s a little different when it comes to a city project that needs lighting–unless city ...
