The linear LED power supply or the linear LED driver is in high demand in the lighting industry. The increased demand is because of the low production costs and simple architecture. Furthermore, linear drivers have descriptions like the constant voltage power supply and the LED ultra-thin strip power supply. If you want to buy a linear LED driver, you must know everything about it. Below is all you need to know of the linear LED drivers.

Linear LED power supply definition

The Linear power supply is a driver that uses non-switching and linear methods to regulate power on LEDs. It uses linear regulators to control DC voltage. The regulators consist of an operation amplifier, internal reference voltage, pass transistor, feedback voltage-divider, and an output capacitor.

The error or operation amplifier ensures that the output voltage is at the necessary value. It regulates the power switch and monitors the feedback voltage divider to ensure optimal output voltage.

 

The linear regulators’ dropout voltage is minimum. Any voltage below the minimum can cause the power supply to stop working.

The drivers are popular in the lighting sector because of their small circuit size, low noise production, simpler architecture, and minimal part count. Most manufacturers use the linear driver’s technology to lower the LED power supply cost.

Linear LED power supply design specifications

1. Manufacturers make the linear LED power supply using a few components

The linear drivers are very cheap compared to the switch-mode drivers. The main reason for it is that manufacturers make them using few parts. The few components ensure that the power supply is not bulky.

2. The input and output power ratio is the same

The linear LED power supply has both the input and output power in the same range. The power supply maintains efficiency by ensuring that the linear regulator’s dropout voltage is minimum. The quiescent current of low power devices should also be minimal to ensure efficiency. Thus, the linear power supply operates best where the input and output power level is equivalent.

3. It relies on its housing for insulation

The LED drivers use the insulation performance present on their housing to ensure safety. It means that the housing is accountable for limiting heat transfer. The LED driver usually has a breakdown path with high voltage throughout the control circuitry. Its housing helps with the insulation issue. But the critical point is that it is always essential for linear drivers not to run extremely high voltage.

4. Has low noise

Manufacturers make the linear LED driver with low noise in mind. It is one of the quietest drivers present in the market. The main reason for the low noise production is the lack of high-frequency switching. The low noise feature ensures that it is perfect for regions that need low ripple, excellent transient response, and low electromagnetic emissions.

Conclusion

The linear LED power supply popularity is on a constant rise. The main attributing factor is that it is very affordable. Furthermore, the low noise present ensures it is perfect for environs that need silence. The simple design also makes its demand to be high.

The iPhone 13 series is official, but as it’s already shaping up to be a modest update over last year’s iPhone 12 family, rumors are beginning to pile up at an alarming rate regarding the much more interesting iPhone 14 that’s slated for 2022. Indeed, we seem to be hearing more and more enticing bits of rumors and news about next year’s iPhone than the one that arrived in September 2021. That’s interesting, to say the least.

So, what have we been hearing, exactly? As mentioned, quite a lot, but it’s important to say that due to the unofficial status of the iPhone 13 and the iPhone 14, it’s possible that some early rumors and leaks have referred to the wrong iPhone generation. However, with the iPhone 13 release date nearing, the chance of Apple surprising us with a totally unexpected feature or design choice grows less and less probable.

Apple iPhone 14 Release date

Apple is one of the more predictable tech companies, in a sense that it has pretty concrete announcement and release time frames. No matter what happens, we always expect iPhones to be unveiled in September and released on the market shortly after, in a week or two’s time. This is why we expect the iPhone 14 to be announced and released in mid-September 2022, which is the usual iPhone announcement period for Apple. Of course, something unexpected could theoretically change that timeframe, but the chances are low – the iPhone 14 release date is in September 2022.

iPhone 14 Price

Let’s get the obvious out of the way — we don’t really expect any surprises with the pricing of the future iPhone 14-series. Although it’s too early to expect anything particular about the iPhone 14 pricing, chances are it wouldn’t differ that much from the iPhone 13-series. Thus, the iPhone 14-series could have the following price tags once they launch:

• iPhone 14: $799+
• iPhone 14: Pro $999+
• iPhone 14: Pro Max $1,099+

It’s important to say that the iPhone 14 Pro max could potentially get a lot more expensive due to an upcoming camera overhaul that could very well increase the costs. Of course, given the timeline, we could very well be off by a certain amount here or there, but generally, we don’t expect a colossal spike in prices for the iPhone 14 series, though if we see such a price hike, it would most certainly be for the Pro models.

Apple iPhone 14 Design

The general design of the iPhone 14 is expected to remain mostly the same: similar frame shape with equally impressive rear camera bump. It doesn’t seem as we’re going to see a smaller rear camera bump as on the Galaxy S22 Ultra.

As per some early rumors, some iPhone 14 representatives could actually feature a titanium frame, unlike the stainless steel one that’s found on the current lineup. According to JP Morgan Chase investors, The Pro models from the iPhone 14 series will be the first iPhones to have titanium alloy chassis. The latest iPhone models are currently made from stainless steel and aluminum. The titanium alloy material is used for the case of some Apple Watch Series 6 models.
Potentially representing the second major iPhone redesign since the iPhone X was introduced in 2017, the next-generation iPhone 14 looks set to bid adieu to the controversial notch and hello to a floating cutout, similar to the ones found on recent Samsung flagships. The latter houses what seems to be the front-facing camera, signaling that Apple isn’t quite ready to adopt the under-screen camera technology that Samsung included on the Galaxy Z Fold 3 as recently as last month.

The under-display camera technology, or at least its iteration at the moment, relies on covering the hole, needed for the selfie camera, with another tiny display. Its resolution and pixel density are quite different from the main one, resulting in a patch that’s easily visible with the naked eye. Face ID could also benefit from this tech in the future, but the Pro models will likely get this feature first.

Either way, if Apple moves forward with this design, it’d arguably stand out less than its current Pro models. The Android world is full of punch hole camera smartphones, so Apple might find itself relying on its brand recognition more than ever to stand out from the crowd. It would just be a bit harder to go “Look, that’s an Apple iPhone!”. A hole punch cutout for Face ID doesn’t have the same ring to it.

In addition to the changes up front, Apple is reportedly planning several design tweaks on the rear and sides. For one, the stainless steel frame that Pro users have become accustomed to is reportedly being switched out for a titanium construction. Surely, that wouldn’t be on just about any iPhone out there, but most probably remain an exclusive version of the Pro models. Who knows, it could be just the design element to differentiate the lucrative 1TB storage option from all other iPhones.

Much like the iPhone 4, which was released in 2010, the iPhone 14 Pro Max model could use circular volume buttons on the side. The rear glass, which is once again glossy and sits on top of the Apple logo, is expected to extend over the sides a little and sit on top of the antenna bands too, another iPhone 4-like design choice. Regardless, the iPhone 14 lineup will likely score small design updates here and there.

Projectors are divided into different types with regard to their technology. The three well-known types of projectors that users will find on the market are:

• DLP projector
• LCD projector
• LED projector

We present these three types below.

The abbreviation DLP stands for “Digital Light Processing”. Most DLP projectors are equipped with a color wheel and a chip that contains numerous tiny mirrors. The devices can display lower contrasts than LCD projectors. Further advantages of a DLP projector: They are very bright and have very good response times. Compared to LCD projectors, DLP projectors are less sensitive to dust and do not have to be serviced as often.

The disadvantages: DLP projectors are more expensive and often louder than LCD devices during operation. Their color fastness is lower. When watching movies with the best projectors, a rainbow effect can occur in some cases. The primary colors flash within the video, especially in scenes that are very high in contrast. Not many people perceive this effect and not all of them find it disturbing.

LCD is the abbreviation for “Liquid Crystal Display”. The lamp of an LCD projector produces light that is split into the colors green, blue, and red by a dichroic mirror. The light is then brought together again in a prism by three LC displays (red, green, and blue). In it, the images from the different shades of color are superimposed and projected onto the wall as a color image. Today, LCD projectors are also called 3LCD projectors to indicate the three LCDs in different colors in the projector.

Most LCD projectors are smaller than DLP projectors, have a lower weight, cost less, and have a higher colorfastness. In addition, the devices sharply delimit the pixels from one another. In this way, users can easily recognize and read graphics or text.

The disadvantage is that a so-called fly screen effect occurs with some LCD projectors. The individual pixels can be seen in the images. The effect occurs only rarely today and especially in models in the lower price range with a low resolution. Another disadvantage is the LCD memory effect. The image is burned in when a user leaves the projector for a very long time on an image. This can cause ghosting. Screen savers, which keep the picture constantly moving, can help against this. LCD projectors offer lower black levels and are more susceptible to dust and are more expensive to maintain.

The LED projector

With an LED projector, the image projection is technically the same as with a DLP or LCD projector. The devices are equipped with LED projectors instead of a UHP lamp. This makes them more environmentally friendly, lasts longer, and uses less energy. In addition, less heat is generated when using an LED projector. The rule of thumb is: LED video projectors are usually quieter. Other advantages: They are lighter and more compact. Most LED projectors are weaker and have a lower luminosity than DLP or LCD projectors with UHP lamps and have a lower contrast ratio and a smaller projection area.

There are also other display technologies, such as LCoS. This is the abbreviation for “Liquid Crystal on Silicon”. This refers to a technology that has special panels to create images in projectors. They are similar to LC displays, but they work reflective. Projectors with LCoS have a sharp image and high contrast. However, the image quality deteriorates over time. In addition, dragging occurs here, so that the dragging effects are also one of the disadvantages. The best-known LCoS variant is SXRD from Sony.

Which projector is suitable for which purpose?

If you want to buy a projector, you should ideally orientate yourself towards the intended use. In the following paragraphs we show three common areas of application for projectors and explain which device is suitable for the respective purpose:
