LED strip lighting systems, also known as LED tapes or LED ribbon lights, have become increasingly popular due to their versatility and energy efficiency. These lighting solutions come in various forms, including flexible LED strips, rigid LED strips, Zhaga LED strips, backlight LED strips, flexible backlight LED strips, and power LED strips. In this article, we will delve into the different types of LED strip lighting systems, discussing their unique features, advantages, and potential applications.

Growing plants in closed and fully controlled environments, under artificial lighting is method of growing popularity. There is also increasing competition to have results at a low cost and as fast as possible, thus the lighting system plays a crucial role.

Below you will find a quick guide how to build the most efficient lighting system.

1) Research, research

Understand what spectrum and intensity of light your plants need.

2) Choose the right PPFD and light color for your plants

With the latest technology achievements, special or full spectrum white light LEDs are the most efficient and cost effective light sources for plant growth. With 3000K white color temperature you will have more pleasant looking plants while with 5000K you obtain faster growth.

With our Nichia 757 Rsp0a LEDs with white light for special spectrum for plant growth or full spectrum Nichia Optisolis CRI98 LEDs your plants will grow up to 50% more than conventional light, including standard white LEDs, a combination of red and blue LEDs or a fluorescent tube, for lower energy consumption.

Nichia, a pioneer in the world of phosphors and LEDs, has commercialized the H6 Series by combining its expertise in these fields with more than 50 years of experience in "LIGHT" and a focus on the "quality of light". By utilizing a unique red narrow band phosphor technology and optimizing the light spectrum, Nichia has achieved a breakthrough in LED technology, surpassing the trade-off between efficacy and Color Rendering Index (CRI). This innovation marks the beginning of a new era of LED adoption, with an emphasis on the quality of light. The Nichia H6 Series portfolio spans from Mid Power to COB and can be employed in diverse applications such as shops, offices, homes, and healthcare facilities.

Over the last decade, there has been a significant shift from fluorescent to LED light sources; however, striking the right balance between color quality and luminous efficacy has remained an ongoing challenge. The accelerated adoption of LED lighting in Japan was propelled by the power shortage that followed the Great East Japan earthquake in 2011. The focus then turned to energy efficiency and luminous efficacy to overcome the power crisis. At the time, the technology could not deliver the high levels of luminous efficacy and color rendering found in tricolor fluorescent lamps. 

The New EU Energy Label: Key Changes and Implications

The new energy labels apply to four product categories: fridges and freezers, dishwashers, washing machines, and television sets (and other external monitors). From September, they also apply to light bulbs and lamps with fixed light sources, including LED bulbs, LED strips, and LED fixtures.

The primary change in the new EU energy label is the return to a simpler A-G scale, replacing the previous A+, A++, and A+++ ratings, which had become increasingly common, particularly for LED lights. This change was implemented to ensure clarity for consumers and motivate businesses to innovate and develop more energy-efficient products, contributing to a reduction in greenhouse gas emissions.

The new A-G scale is stricter, with only a few products initially able to achieve the "A" rating. This approach leaves room for future advancements in energy efficiency. Consequently, the most energy-efficient products from the past will now typically receive "B", "C", or "D" ratings. The updated EU energy label for LED lights, compared to the old one, can be seen below:

White light is a combination of different wavelengths

To understand the CRI color rendering index, we need a brief explanation of how sunlight is perceived as white.

Glass prisms are an easy experiment to visualize the composition of sunlight. It shows white light is a combination of different wavelengths in the electromagnetic spectrum.

To have white light from an artificial source, a mix of different emitted wavelengths is required. However, a close analysis of the white light of artificial lighting shows that not all white light is the same.

LED backlighting is a popular and versatile lighting solution that can be used in various applications, from linear lighting fixtures to luminous ceilings and illuminated signs. Achieving the perfect balance of total luminous flux and individual LED visibility is crucial for successful implementation. This article delves into the essential aspects of selecting and positioning LEDs for backlighting applications, ensuring optimal performance while meeting project requirements.

Understanding the Basics of LED Backlighting

LED backlighting involves placing light-emitting diodes (LEDs) behind a diffuse cover to create uniform and visually appealing illumination. Common applications include:

1. Linear lighting fixtures: LED strips or tubes used for accent, task, or general lighting in residential or commercial spaces.
2. Luminous ceilings: Large, uniformly lit surfaces that create a sense of spaciousness and enhance the aesthetics of interiors.
3. Illuminated signs: LED backlighting is used to create vibrant and eye-catching signs for branding, advertising, or wayfinding.

The ABCs of energy efficiency

A lighting installation can be energy efficient in three ways:

A) The light is emitted with the lowest possible energy consumption.

B) The total light output of the installation is at an optimum, as defined by its purpose or the activities it needs to support.

C) The composition of the white light is on tune with the sensitivity of our eyes.

NICHIA, the world’s largest LED manufacturer and inventor of the high-brightness blue and white LED, has launched a high density UV-C LED that can help target the inactivation and sterilization of various bacteria and viruses. The new NCSU434B UV-C LED is only 3.5×3.5-mm and offers a high radiant flux of 62 mW operating from 350 mA. Nichia has also documented the germicidal efficacy.

The ultraviolet (UV) performance in the germicidal UV-C band (100–280 nm) has been documented to deactivate including SARs-CoV-2 virus that causes COVID-19. The LED is suitable for usage in water, near-surface, and air disinfection systems, and is commercially available immediately.

LED strips and modules used for lighting fixture use, in general, multiple LEDs.

As operating a single LED generates heat, more is generated when multiple LEDs are mounted on a PCB, due to the mutual effect. As such, in the case of LED strips or modules, the junction temperature (TJ) of each LED gets higher, compared to a single light source. This leads to the decrease in the LEDs lifetime and luminous flux.

For LED strips and modules, a better thermal management is required to minimize TJ and allow a longer lifetime of the installed products. For this purpose, the LED pitch, the PCB base material and the use of aluminum profile must be taken in consideration.

Linear LED light fixtures and LED tubes also feature a cover that protects the LEDs and diffuses the light. This cover is usually made of polycarbonate (a resin) and sometimes of glass. 

The cover has a certain light transmission rate that impacts the light's luminous flux and glare. If a cover has a high transmission rate, it will minimize the depreciation rate of the lamp’s luminous flux by reducing the light diffusion. However, the light of individual LED’s can be visible, increasing the glare effect.

Below, we present an evaluation of four covers to showcase light transmission and glare.
