Lighting as a Design Tool

LEDRecessedDownlight

Great lighting should be your first consideration for creating a spectacular space. It is a design element that is often overlooked, but lighting can make a big difference in the overall feel of the room. The right lighting not only illuminates great design, but it also becomes a part of it.


Add Space Without Renovating

The right lighting can transform a space without changing anything else about the room's design. For example, by simply adding more light, you can make a room seem larger. Why? Because humans naturally associate darkness with being closed in. Adding light will make the room feel larger because the colors in the room will be brighter.

Change the Feel of a Room

Light not only changes the size of the room -- it also transforms the feeling of the space. Darkness can feel gloomy or depressing. Adding more light to a room can also make it feel cozier and more aesthetically pleasing.

Light Alters Colors

The light quality coming from your fixtures also makes a big difference. Average lighting can cast a yellow glow around your room, changing the decor colors you worked so hard to pick out. Using high-CRI lighting such as P-tec's Ultra-Thin LED Recessed Downlight produces white light that keeps your colors looking the way you intended.

Remove Distractions

Though adding more light is a great design idea, changing the type of lighting you use can also boost the aesthetics of the room. For example, an ugly chandelier that dips down in the center of the room can be a design distraction. It is much better to go with lighting features that blend into the design of the room.

The right choice of lighting can also leave your space more streamlined. For instance, instead of using lamps or other lighting features that take up space, you could choose an Ultra-Thin LED Recessed Downlight that isn't intrusive to the design of your space.

The next time you decide a room needs a change, consider simply changing the lighting. You can make your room seem larger, cozier, or more elegant just by choosing the right lighting.

Advances in Color Rendering for LCD Displays

At a time when LCD screen sizes seem to be struggling to set a reasonable minimum, maturing technologies are providing much better color depth for greater realism. For a long time, the "True Color" standard has been 24-bit with 256 shades each of red, green, and blue, producing about 16 million distinct shades. The RGB color picker in Photoshop defaults to this format.

The eye can distinguish a much greater range than this, and in 2008 Hewlett-Packard introduced its 30-bit DreamColor LCD display, developed with DreamWorks, that could show more than a billion tints. It was expensive, and used primarily in graphics and video studios. The newest version of this monitor is the z27x LED, which is dramatically lower in cost and may appeal to a wider audience.

The effect of this great increase is primarily apparent in the shadows, transparencies and gradients that come with very high resolution images and videos. With graphics chips as powerful as they have become, such added realism can be viewed without flicker or artifacts, as long as sufficient bandwidth is there to stream the file.

There is a new format coming for TV: Ultra HD 4K, which supports 32-bit color and  a native resolution of 3840 x 2160 pixels. This is the standard for movies these days, meant to be seen in theaters from special high-definition projectors. The transition of this standard to your personal screen depends on sufficient bandwidth for streaming or broadcasting, and would require technology to upsample the 24-bit BluRay DVD to the higher resolution. But the technology is certainly ready for the hardware right now, whether or not you can provide the signal.

On the smaller end of the scale, thinner and flexible LCD screens seem to be making a commercial presence, resulting in thinner screens that may even fold or roll up. These are being developed for portable devices and the issue of resolution would seem to be moot, except that truly tiny, high-res screens that can cast an image directly on the retina of the eye may have an important place in the immediate future. LCD displays are getting larger and smaller at the same time, and there is a wide range of intermediate sizes—between mini tablets and desktop computer monitors—that continue to reap the benefits of the developing technology.

So the immediate future will be rich in colorful images as these new technologies are brought together.

What Are Light Emitting Diodes (LEDs) and How Do They Work?

Chances are, you see light emitting diodes (LEDs) every day. They are used to illuminate all kinds of public spaces, displays, technology screens (you might be reading this through one right now) and they are put to myriad uses in daily life. But have you ever wondered how they actually work to emit light? Here is an overview of the science behind LEDs.

P-tec LED Diagram.jpg

How Do LEDs Produce Light?

Unlike a standard (incandescent) bulb, an LED doesn't have a filament inside of it. Instead, it uses a semiconductor that is coated with a material to make it conduct electricity, which then produces light. Typical LED lights use silicon crystals, which are semiconductors that have a stable electron bond. The coating destabilizes that electron bond and allows the crystals to conduct electricity. Negative electrons then flow into what are called holes in P-type (positively charged) material, emitting light as they do so. The current of electricity flows between the anode and cathode of the LED light and its battery.

What Determines the Color of an LED?

The color of an LED is determined by the material used in the semiconductor chip, the wavelength of the light and the band gap (the state in the semiconductor where no electrons can exist). While many use silicon, other materials are more common in colored LED lights. The wavelength is highest for infrared LEDs and gets progressively lower as you look at colors moving down the rainbow spectrum from red to violet, with white and pink having a broader spectrum of wavelengths. Aluminium gallium arsenide (AlGaAs) is used for infrared and red LEDs. Gallium arsenide phosphide (GaAsP) is used in red, orange, and green LEDs. Aluminium gallium indium phosphide (AlGaInP) and Gallium(III) phosphide (GaP)  are used in red, orange, yellow, and green colors. Indium gallium nitride (InGaN) is used for pure green, blue, and violet.

This is just a brief overview of how LEDs work. They are more sustainable than standard lights and are found in a variety of brightnesses, from the kind seen on holiday decorations to ones that light up entire billboards. 

Researchers Show Low Temperature Deposition Of GaN For TFTs

compoundsemiconductor.net is reporting on a study that shows the possibility making flexible substrates by using Gallium Nitrate (GaN), instead of the usual amorphous Si.

Researchers at the Bilkent University in Turkey have grown GaN thin film transistors (TFT) with a thermal budget below 250 degC. The study, they say, demonstrates the possibility of using low-temperature atomic layer deposition (ALD)-grown GaN layers to make stable flexible/transparent TFT devices.

TFTs, usually based on amorphous Si (a-Si), are the driving elements of liquid crystal display technology. However, due to low carrier mobility in a-Si, high fabrication thermal budget, and strong absorption of visible light, a-Si is not suitable for flexible and transparent electronics applications. Transparent metal oxides, in particular ZnO, have been proposed instead but stability remains an important problem.

Understanding the Difference between Projected Capacitive Touch and Resistive Touch Panels

As the mobile computing sector experiences an explosion in growth, understanding the touchscreen technology that drives user interfacing is more important than ever. After decades of development, both projected capacitive touch (PCT) panels and resistive touch panels (RTP) are capable of providing precise, reliable input solutions for manufacturers, readily available through P-tec’s products.

What is Projected Capacitive Touch?

PCT technology operates by laying one or more grids of conductive transparent material over glass or another insulator. The grid allows the formation of an electrostatic field that can then be used to track input. When a finger or conductive object comes in contact with the field, it disrupts the electrostatic charge. That disruption is then tracked along X and Y coordinates to determine the point of input. Panels like P-tec’s TFT LCD Display Modules can harness this input to allow precision control of the on-screen interface.

PCT technology can overcome the limitations of prior Capacitive Touch solutions in that it can register input from an object with poor conductance, allowing use with a gloved finger or passive stylus. While it offers higher input resolution than RTP alternatives, it can still suffer from ghosting or muddled tracking if dust or moisture gathers on the panel.

What is Resistive Touch?

RTP technology utilizes two separate layers of conductive material separated by a gap to sense user input. An electric charge is applied to one layer so that pressing on the panel brings the two layers into contact, transferring that charge between them. The point of conductance is then measured along X and Y coordinates to establish the contact location and determine input.

Resistive touch solutions are often cheaper to construct than capacitive alternatives, but can be prone to damage, as the top conductive layer requires a degree of vulnerable flexibility to operate. While RT panels provide relatively poor input resolution, innovations in the technology allow RTP modules like those available at P-tec to overcome this limitation through software and controller advances. They allow more precise control and even multi-touch capabilities. Additionally, the pressure-sensitive nature of the technology allows input from many sources, regardless of their conductive properties.

The Future, Now

As liquid crystal displays become prevalent in devices of every shape and size, the future for PCT and RTP technology at P-tec is promising. Touchscreen input is fueling a paradigm-shifting burst of innovation in electronics design, and it seems increasingly likely that the average consumer will come to rely on these screens in every aspect of their lives in very short order.

Improving the Quality of Office or Commercial Space by Switching to LED T8 Linear Lamps

LEDT8TubesinWarehouse
LEDT8LampsinOffice

Gone are the days that lighting only served the purpose of illumination. With the onset of contemporary lighting solutions such as LED T8 Tubes, spaces transform into art forms, and commercial space transforms into signature institutional identifiers. With the creative use of P-tec’s LED tubes, one has access to high color-rendering index solutions (in some cases greater than 90CRI). This gives all object the true rendering of their natural color. This is especially effective indoors in areas where natural light does not reach.

Switching to LED T8 Lamps is Easier Than You Think

Switching to LED lamps need not be a tedious process, especially in terms of replacing fluorescent lamps. For instance, the relative ease of switching to LED T8 lighting comes from the fact that our T8 linear lamps fit into most conventional linear tube fixtures. Moreover, P-tec offers select T8s that do not require ballast removal or rewiring. Simply pop them into place and forget about them for years to come.

LED T8s Consume Less

Conventionally, LED lighting products feature very low energy consumption. This, however, does not jeopardize the luminous intensity output from the tubes. Our energy-efficient LED T8 lamps are available in color temperature ranges from 2700 upwards, and luminous intensities that match or beat their fluorescent counterparts.

Eliminate Maintenance and Relamping

Virtually no maintenance costs and the exceptionally long lifetime of LEDs make them a truly revolutionary form of lighting. For instance, P-tec’s linear LED T8 lamps feature lifetimes of about 50,000 hours. This not only adds to the economic appeal, it also guarantees service for a long time and eliminates the need for relamping.

We've got a new look!

Our hope is to capture and convey the nature of light as it shifts colors and moves through space. 

We've designed several versions ready to be downloaded and used in various designs and applications. Please visit our branding guidelines page to learn how you can download and implement our new logo. 

Additionally, we ask that you or another relevant party at your company immediately swap out the old P-tec logo on your website with this new one. It will be important for us to convey a single visual identity online and we'll need your help to do so.

6 Reasons LED T8 Tubes are better than fluorescent tubes

LEDT8vsFluorescents.png

In just a few years, LED T8 Lamps have come a long way. Nowadays, brightness, quality of light, and durability of LED lighting products meet or exceed the standards set by traditional light sources like fluorescent or halogen. LEDs don't stop there, however. In many key areas, LED lighting products like our T8 lamp are the clear choice for a variety of lighting needs. Here are our six favorite:

 

1. LED T8 Lamps contain no mercury or other harmful toxins

Fluorescent T8s contain toxins like mercury which make them a pain to dispose of. This alone makes fluorescent tubes environmentally unfriendly and incredibly dangerous if handled improperly. LED T8s eliminate this problem altogether. They're easy to dispose of (after years of continuous life, of course) and they contain no harmful toxins. 

2. LED T8 Lamps last for years

By switching to LED T8 Lamps, you're effectively eliminating your need to worry about lighting for years to come. Our T8s are rated for 50,000 hours of continuous life (at which point lumen output reaches 70% of initial output).  

3. LED T8s are rugged and durable

Gone are the days where light tubes and light bulbs shatter when you drop them. LED lighting products like our T8s are built to last. Drop them, smash them, do what you gotta do, chances are, they'll still work just fine.  

4. LED T8  Tubes are highly energy-efficient

If your goal is to be as green as possible, LEDs are a great start. LEDs are roughly 80% more efficient than incandescent lights and up to 50% more efficient than fluorescent lights. This means that switching to LED lights can drastically drop your monthly energy usage. Who doesn't like saving money? 

5. LED T8 Tubes reach full brightness instantly

Are you tired of waiting for fluorescent tubes to "warm up"? LED T8s reach full brightness instantly without the buzzing, humming, and flickering that you're used to with fluorescent lights.  

6. LEDs operate well in a wide variety of environments

Whether you need to illuminate your office or a refrigeration unit, LED T8s work great. With an operating temperature of -40ºC to +85ºC, LED T8s will give you great performance in some of the world's most demanding lighting applications.
