The price of lighting LED continues to rise

According to a report released by TrendForce, the overall price of LED products for lighting in the second quarter of 2021 will rise by 0.3~2.3%. It is estimated that the rising trend of the supply chain will drive the annual output value of LED for lighting to US$6.709 billion, an annual growth. The rate is 3.43%.

The price of lighting LED continues to rise

This wave of LED packaging products has increased categories, including indoor medium and low-power lighting LED products (under 1 watt, excluding 1 watt) for home and commercial use, such as 2835 LED, 3030 LED and 5630 LED, with a seasonal increase of 0.3~2.3 %, as well as outdoor high-power lighting LED products (above 1 watt) for outdoor and industrial use, such as ceramic substrate LEDs and 7070 LEDs, with a quarterly increase of 1.3~1.8%.

TrendForce’s analysis believes that the price increase is mainly due to the full recovery of the LED lighting market demand since the first quarter, and the high-end remained in the second quarter. In addition, the structural shortage of upstream LED chips caused by the epidemic is still unresolved. In order to avoid falling into the shortage situation last year, product manufacturers have increased their stocking efforts.

Looking at this wave of price increases from the perspective of the supply chain, due to the impact of the epidemic last year that caused the chips and related metal raw materials to rise, some lighting LED manufacturers are facing the pressure of upstream price increases, and they have increased their previous sales of low-priced lighting LED products. In order to maintain profit fundamentals.

Benefiting from the rapid growth in demand for human lighting, smart lighting, plant lighting, and special lighting (such as nuclear power plant lighting, pharmaceuticals, metal processing industry lighting), major lighting-level LED packaging manufacturers to include Samsung LED (Samsung LED), ams semiconductor and Osram (ams / OSRAM), CREE LED, Lumileds, Seoul Semiconductor (Seoul Semiconductor), MLS (MLS), Tiandian (Lightning), etc. have all grown significantly in revenue since the first quarter, and growth momentum is expected to continue to the second season.

On the whole, despite the pressure of rising prices of upstream raw materials, lighting LED manufacturers are still actively improving product performance, including luminous efficacy and color saturation, and successively launching related products that meet the new needs of the post-epidemic market to consolidate their own market share. And competitiveness, such as OSRAM and Lumileds launched lighting LED products created by the architectural atmosphere, and CREE LED products suitable for indoor planting and plant factories.

LED lighting promotes high energy efficiency

For residential and commercial lighting, we need a high-voltage alternating current (AC) power source to power our LEDs. But LED needs lower voltage and direct current (DC). In order to convert alternating current to direct current at the right voltage, we need appropriate drivers and other power management devices-these inevitably bring some inefficiencies, and we obviously want to minimize its impact on energy efficiency.

LED lighting promotes high energy efficiency

Depending on the current and color, the forward voltage of the LED may vary from less than 2 V to 4.5 V. Companies like ON Semiconductor has been the drivers of LED adoption, using their expertise in power management to develop the required devices to drive LEDs reliably and efficiently.

For example, ON Semiconductor’s NCL30082 is an LED driver (as shown in Figure 2), designed to use AC input power. It includes a pulse width modulation (PWM) current-mode controller that provides high energy efficiency, a new control method that reduces the number of external components required. The driver also supports LED dimming. ON Semiconductor also provides input bridge rectifiers and super junction MOSFETs to complete the power conversion circuit to drive LEDs.

Like LED drivers, lighting applications require other devices to create a complete system. This includes sensors, such as detecting the ambient light level so that the LED brightness can be adjusted automatically, or turning on the light when it detects someone in the office.

Another device required in some applications is an LED bypass shunt, such as ON Semiconductor’s NUD4700. This ensures that if one LED fails, the shunt allows current to flow around the failed LED, keeping the rest of the LED string lit.

Sweden IKEA grows lettuce in containers

Outside the IKEA stores in Malm? and Helsingborg, Sweden, there are containers, and IKEA is trying to grow lettuce inside. It is expected that these vegetables will be supplied to the nearby store restaurant soon.

Sweden IKEA grows lettuce in containers

For IKEA, this is a step towards environmental sustainability. Catarina Englund, Ingka Group, which manages IKEA’s near-global stores, said: “We need to find a better way to produce healthier food, use less land and water, and reduce food waste. ”

“Urban farming can focus on producing local, fresh ingredients while consuming less natural resources to meet the needs of neighboring areas, and thus has the potential to change the current food value chain.”

In each container, the hydroponic planting system can grow 4 layers of plants, up to about 3,600 lettuce plants. There is no soil, no pesticides or herbicides, and like other indoor farming systems, this system uses 90% less water than planting on the ground. The LED lights hanging above the plants use renewable energy to help the plants grow quickly.

In addition, the restaurant will also use food waste to transform it into nutrients needed for lettuce. Fredrik Olrog, co-founder and managing director of Bonbio, the supplier of IKEA’s indoor planting system, said: “The raw materials we use to fertilize are made from kitchen waste, and this is what makes us unique: we try to make the farm is in line with the spirit of circular economy.”

The hydroponic planting system can grow 4-layer plants. There is no soil, no pesticides or herbicides. The LED lights hanging above the plants use renewable energy to help plants grow quickly.

Bonbio’s parent company, OX2, is an enterprise that specializes in refining oil from food waste. In the process of oil production, by-products such as nitrogen and phosphorus are produced, which can provide important sources of nutrients for crops, and OX2 has also found a way to extract these nutrients as fertilizers. In other words, the food waste produced by the IKEA restaurant can be used to help more crops grow.

“Bonbio operates a completely closed loop system in two IKEA in Sweden-we did use the food waste from the IKEA restaurant to make IKEA’s own dishes grow better.” Olrog said.

Speaking of the cooperation with Bonbio, Englund said: “We will explore how to grow fresh, healthy and sustainable salad lettuce in vertical farms at a cost that is not higher than traditional cultivation to achieve self-sufficiency.”

Regarding why this indoor planting project started with leafy vegetables, Englund explained: “As far as the situation is concerned, it is easiest to grow vegetables with a short growth cycle and high yield per unit area, such as lettuce and cabbage.”

In Sweden, lettuce has long relied on foreign imports. The winter here is cold and gloomy, which makes this place an excellent place to test the system. Vegetables grown on the ground not only taste better, but also avoid emissions caused by transportation. In a one-year test, Ingka and Bonbio will study how much lettuce this system can produce and how the nutrients currently used affect the nutritional value of the end food.

Englund explained: “Our goal is to prove that the concept of vertical farms is feasible under the operation of IKEA, and to establish and optimize the implementation process.” In these two pilot stores, IKEA expects to supply this batch of lettuce to employee restaurants first. When the manufacturing process is more mature, it will be officially supplied to retail restaurants.

Although for IKEA, food only accounts for a very small part of the company’s overall carbon footprint, as a whole, as the whole company pays more and more attention to sustainable practices, such as moving towards a circular economy model, and recently trying to implement “furniture leasing”, working hard on ingredients is also part of the solution to carbon reduction.

Globally, more than 30% of emissions that affect the climate are related to food. In addition to adding vegetable balls, vegetable hot dogs and other vegetable-based meals to the store menus, IKEA is also committed to halving food waste. Their next step is to grow their own ingredients, and ultimately hope to make IKEA’s carbon reduction greater than its carbon emissions-that is, to promote to the realm of climate positive.
