Why Are Driverless LED High Bay Lights So Cheap?

Buy Driverless LED High Bay Lights

Light emitting diodes (LEDs) have gained popularity in the lighting technology due to their many uses. For a continued operation of an LED light, it needs to be fitted with a driver, and this is why many traditional LEDs needed a driver that was used in controlling the electrical current so that it could supply clean DC power to it. The driver acts as a current within a specific range such that it is high enough to power the LED but also low enough to prevent any permanent damage.

These drivers, however, come with their own shortfalls, and that is why driverless high bay lights were invented. You might be wondering what driverless LED lighting means. The driverless LEDs use a high voltage circuit that comes with regulating and changing chips that help alter the quantities of LEDs in a string within an electrical cable cycle to ensure the LED’s string voltage matches the electric cable voltage.

This new technology adopts the high-quality USA IC on board in order to replace the usual driver. With a driverless product, which has no electrolytic capacitor, you increase the lifespan. It is unlike the regular product that comes with a driver.

These LEDs have a semiconductor that emits light. Unlike the traditional bulbs that rely on vacuum or gas released light, LEDs get their light from solid matter, making them be classified as solid-state lighting (SSL) kind. Applying a high voltage that is enough to the semiconducting material makes electrons to move pass and go through holes releasing photons.

What is a COB LED?

Chip on board (COB) products are gaining popularity in the market and might even take the entire industry by storm. What a COB LED means is that a LED chip diode is built directly on the circuit board. This is usually done by the manufacturer. Since there are fewer components in the LED chip, the thermal conductivity gets directed at the circuit board, leading to 25% less heat emission from the chip. With less heat comes lower failure rates and higher efficiency.

Since the chip is put directly on the circuit board, there is no need for soldering. When there is less welding, there exist fewer chances of failure. There is no need for PC lenses and any other traditional LED packaging parts, which in turn, increase the light visibility range while reducing light loss from lenses. With all these factors, the LED chip can last longer.

COB LEDs come as an integrated package that has less spacing between the chips and a wider surface that can be covered by the COB LED’s light beam while producing minimal glare. Also, CRI gets increased by the wider beam angle.

Innovative Circuitry

The first versions of driverless LEDs worked through a circuit where the AC line gets converted to DC. It then goes through a series of LEDs. This leads to a flash of white light getting released by the circuit at a frequency of 120 flashes every second. The result is a light quality similar to that emitted by a fluorescent tube that is stabilised by magnets.

A switching system was introduced to improve this design. When you place a switch for every LED in a parallel circuit to the first one, this allows you to change the number of LEDs that are in the series easily. Various systems that operate this switch mechanism have been developed with some replacing the simple resistor with a current-controlled resistor or even a circuit that has a current limiter.

This circuit arrangement comes with one downside; the high voltage switches needed for the switching mechanism can be very expensive. Also, the IC controllers used are quite costly. The LED current obtained from this segmented switching system circuit is like a succession of half sine waves. Its input current resembles a sine wave. Due to this, the circuit shows a high ratio of real power to apparent power and also a very low total harmonic distortion.

The output resembles a half sine wave, meaning that a frequency of 120 Hz the flicker nears 100%. Generally, this flicker is less noticeable than that experienced in the first circuit as there is always a given level of LED current that is flowing. This means there are always some LEDs that are switched on.

Products that Have Driverless LED

All small LEDs have drivers as they are simply a cheap way of controlling power. However, the solar lights used in homes are driverless. There are various reasons why these fail constantly with the main one being overworked or poor batteries. Another issue is failed circuitry.

The first products that went driverless and still maintained the ability to produce high-quality light are the T8 bulbs. These are a replacement of the previous 4-inch long CFLs that are common in most homes and business premises all around the world. The fluorescent T8 bulbs produce UV/IR high-level light. However, LEDs contain no UV light; this makes them safer than the CFL T8s. These LEDs emit no light in the non-visible light spectrum, making them less harmful to your health. One of the biggest causes for faded fabric and signage colour is UV/IR light. It also contributes to eye strain and eye fatigue, which is why LED light has become so popular.

Various bulbs like T8, T5 and T12 are rapidly getting replaced by LEDs. Another great thing about LED is the fact that it is way cheaper than these previously used bulbs. This makes going driverless the most desirable option.

How it will affect the LED bulbs

For consumers, they can expect smaller and cheaper LED bulbs and light fixtures, and although the quality of the driverless LEDs is high, there will be no real difference to be experienced.

These lights should not end up like cheap solar lights as this will only mean failure coupled with numerous negative reviews and feedback regarding LEDs. Consumers will also benefit by having to pay less for light bulbs as well as other LED light fixtures.

What is Flicker and How Is It Connected to LEDs?

Flicker refers to the rapid fluctuation of light intensity from a source. A light source like the sun gives steady light. However, some artificial lights will give off a fluctuating light, which can lead to various problems.

An LED will illuminate without a flicker provided that a constant current is provided when the power is a direct current (DC). Since an alternating current changes form constantly, it will cause the LED light to flicker. To get over this problem, a driver is installed. Of course, if the rate of flicker is very high, the light will seem to be constant as the human eye cannot detect it. At lower levels, the of-on oscillations of light could interfere with photography and even cause migraines and headaches.

An LED driver regulates the current that reaches the LED light so that the fluctuations caused by changes in temperature and alternating current are eliminated or diminished. The driver helps the LED last longer since it controls the damage that high temperature could cause it. It also enables the light to remain at a constant level of brightness. By ensuring that the current that gets to the LED is constant, it protects the LED from getting damaged by fluctuations in power.

Getting Rid of the Flicker

The most recent driverless design for high bay LED lights eliminates the flicker completely by using a smart reworking of its circuit architecture. The new system holds the LED current near constant, making the output current to experience only 1.5 ms pause two times per power line cycle. This gives the capacitors enough time to recharge.

As this circuit arrangement will result in a frequency of more than 600 hertz, it makes the flicker too rapid to be detected by the human eye or for the brain to even perceive it. The result is light that appears flicker-free to every person, thus eliminating any potential deleterious effects. Unlike all the previous designs, this driverless new architecture does not include pricey power switch chips or any IC driver chips.

How This New Architecture Works in Detail

To better understand how the new driverless circuit architecture works, it is better to start by following its current path direct from the power source. When the voltage increases at the left side of the power source, two capacitors get to receive a displacement current; a current then gets sent via one of the LED arrays, and then back to the power source.

After the input voltage gets to a certain threshold level, it makes an extra current to flow through another LED array, one of the resistors and one of the diodes. So, the first thing that happens is the displacement current flowing via the LED arrays, which is then followed later by a galvanic current.

As the input voltage increases, it makes a third capacitor to be charged up until it reaches its maximum level through another of the diodes. Through this means, two of all the capacitors start to operate in an alternating mode; one gets recharged while the other one discharges. When the potential difference of the input power source goes above or below nought, the completely charged capacitor can then deliver a full output current instantly. As the displacement current begins to go low heading towards the middle of the half cycle, the galvanic current then starts to increase, maintaining the LED current for a longer time. The final output is a reasonable and more stable output current that goes for a long period.

Advantages of the New LED Driverless Technology

With the LED driver removed, it creates a lot of space for innovation and creativity. Now, LED products can be made in whichever shape; be it circular, square, rectangular and many others. They can also be made in any shape without ruining their performance. The result is a simpler design, flatter and more compact. The flat shape means that these LEDs can go to great lengths and still get controlled by just one switch.

These driverless LED high bay lights are easier to move around, and their manufacture costs are also reduced, unlike their previous counterparts. They are also cheaper and require little maintenance. This translates to saving more money by either replacing the lights or the energy bills.
The previous imitates of LED high bay lights came with high flicker rates, which made them unsuitable for most common uses like office lighting or illuminating a mechanics workplace. So, the introduction of a lighting technology that has no detectable flicker makes it okay to install high bay LED lights in the same contexts.

The process of installing driverless high bay LED lights is easier and quicker as compared to the previous type of lights. These driverless solutions weigh less and come with simpler and straightforward fitting. This means you get to save on labour costs.

The absence of drivers reduces the maintenance costs. This is due to the fact that drivers tend to break down and require replacement, which can be a complicated process that needs trained personnel and equipment. All this amounts to a huge amount of money. This also creates the inconvenience of either closing your business premises as the repairs take place or having to spend endless hours as you supervise the ongoing work. Using driverless technology will eliminate all these inconveniences.

Driver on board version: the DOB version is more stable and reliable due to the following reason. It uses smart IC to control the current of the LED products. This means that it doesn’t use a transformer or capacitor at all, unlike the constant current driver. Also, DOB uses solid components, which is unlike the liquid ones used in the previous versions that are likely to explode and have a shorter lifespan.

The IC has a special function, which is to set a security overheat protection. When the chip temperature gets over the safe level, the IC automatically lowers the power of the product to allow it to cool down and takes it back to safe level. This helps protect the product.
While it is not possible to dim previous LED designs, driverless LEDs can easily be dimmed to give a more adaptable and personalised lighting solution. This is because different environments require varying levels of lighting under dissimilar circumstances. The option of dimming lights is ideal mostly for those with eye problems that can get aggravated by bright lights.

Energy savings: high bay LED lighting has high energy efficiency, unlike other lighting types. This is because these lights tend to consume less power and you can even save up to 80% on your electrical bills as compared to when using other alternatives. When you combine this lighting with smart sensors, you will be able to save even more.

Another advantage is that they are long-lasting and cool. Driverless LED lights can last you up to 10 times longer than the common fluorescent alternatives, and they also don’t produce any heat when turned on. This brings in two more advantages; it makes them safer, and you also get to save on cooling costs. You will not have the need for air conditioning while using these lights.

They are very durable to a point where they are damage-proof, which again lowers maintenance costs. Also, they don’t bust easily. When turned on, they go easy on your eyes as they turn immediately, giving you instant light. You can easily turn them on and off.
Any LED lighting tends to distribute light evenly unlike others, and these are no exception. You are bound to notice an 8% increase in your lighting uniformity when using driverless high bay LED lighting. Another great feature is that, compared to fluorescent and CFL lights, they have lesser light distortion and very little static buildup.
