PCR (polymerase chain reaction) optical design and characteristics

PCR (polymerase chain reaction) optical design and characteristics mainly include the following aspects:

The importance of optical design modules: The optical system design of PCR fluorescence detectors is an important direction in the research of PCR fluorescence detectors. For example, a catadioptric system (total reflection lens) designed based on a confocal optical path system can collect collimated light and improve the light energy utilization rate by more than 2 times compared with traditional refractive systems [3]. This indicates that the design of the optical system is critical to improving the efficiency and accuracy of PCR.
Fluorescent quantitative PCR technology: Fluorescent quantitative PCR technology uses fluorescent chemicals to measure the total amount of DNA products after each PCR cycle, and quantitatively analyzes the specific DNA sequence in the sample to be tested through the internal reference or external reference method [4]. This method not only reduces the risk of contamination, but also simplifies the operation process and results in less sample loading [4].
Optical module of real-time PCR system: Aria real-time PCR system is a fully integrated quantitative PCR amplification, detection and data analysis system. Its design combines an advanced thermal cycler and an advanced optical system equipped with LED excitation light source. and a full set of data analysis software [5]. This shows that advanced optical system design plays an important role in achieving efficient and accurate PCR analysis.
Application of optical fiber system in PCR instruments: Use optical fiber system for fluorescence quantitative PCR detection, including excitation light source, excitation light path, fluorescence collection and detection light path. These are the core modules that determine the weak fluorescence detection capability of the system. Usually, the intensity of the excitation light exceeds 1000 times the fluorescence intensity, so the detection of fluorescence signals belongs to the collection of weak signals under strong background signals [7]. This design takes into account the fluorescence signal collection capability to adapt to detection needs under strong background.
Optical system design of multi-channel PCR fluorescence detector: Aiming at the problems of low detection efficiency and large volume in the real-time quantitative PCR fluorescence detector system, a method based on traditional single-channel confocal optical path improvement components is proposed. The excitation light path and fluorescence collection light path share a large aperture lens, and multiple excitation light collimation light paths are surrounded below the lens. This design aims to improve detection efficiency and reduce volume [13].

PCR (polymerase chain reaction) optica

In summary, PCR optical design and its characteristics involve the design optimization of optical systems, fluorescence quantitative PCR technology, optical modules of real-time PCR systems, application of fiber optic systems, and multi-channel design. These designs aim to improve PCR efficiency, accuracy and automation levels.

mini led vs oled

Mini LED and OLED are one of the two main display technologies currently on the market. They have different characteristics in terms of display quality, power consumption, thickness and price.

First, let us introduce Mini LED technology. Mini LED refers to a display technology that uses small-sized LEDs as backlight sources. Compared with traditional LCD backlights, Mini LED uses more sm

all-sized LED beads, which makes the display effect more uniform and delicate. Mini LED backlight can achieve higher brightness and contrast, making the picture more vivid and realistic. In addition, Mini LED’s power consumption is relatively low, extending the battery life of the display device. However, because Mini LED requires more LED lamp beads and has higher manufacturing costs, it is also relatively expensive.

Next, let’s introduce OLED technology. OLED is an organic light-emitting diode technology that does not require a backlight and each pixel can emit light independently. This allows the OLED display to have extremely high contrast and color saturation, allowing it to present very realistic and vivid pictures. OLED also has very fast response speed and wide viewing angle, which can maintain good display effects at different angles. In addition, the thickness of OLED is relatively thin, making it suitable for manufacturing ultra-thin display devices. However, OLED displays may experience “screen burn” when displaying the same image for a long time, and compared to Mini LED, OLED consumes higher power.

To sum up, Mini LED and OLED have their own advantages and disadvantages. Mini LED is suitable for users who pursue higher brightness and contrast, while OLED is suitable for users who pursue more realistic colors and wide viewing angles. Which technology to choose depends on personal display and power consumption needs. With the continuous advancement of technology, I believe that Mini LED and OLED display technologies will have better development and applications.

Spotlight LED luminaires project focused beams of light onto specific objects or areas, thereby achieving more precise lighting control. However, due to its small size and low power consumption, it cannot illuminate large spaces with uniform brightness.

Technical characteristics

In terms of technology, the LED chips used in floodlights are generally thicker and more expensive than spotlights, but their heat dissipation performance is better. Spotlights usually use thinner LED chips, which consume less power and are cheaper, but their heat dissipation performance is poor. Additionally, floodlights typically have more complex circuit boards and heat sinks than spotlights, making them more expensive to produce.

Advantage

Floodlights vs. Spotlights: Floodlights and spotlights are two different types of LED fixtures with unique advantages and disadvantages.

Floodlight LED fixtures are designed to cast a wide general area of light in a large space, similar to a spotlight. However, floodlights have a wider coverage angle and provide more indirect lighting, resulting in a more diffuse and soft lighting effect. Floodlights are often used for general area lighting in commercial and industrial applications that require uniform illumination of large spaces.

Concentrated LED fixtures are designed to project a narrow beam of light into a specific area at a distance, similar to a floodlight. However, spotlights provide more direct illumination and can create more dramatic and intense lighting effects with their concentrated beams. Spotlights are often used to highlight specific objects or areas in commercial and residential applications that require directional lighting.

Light Output:

Floodlights generally produce more light output than spotlights because of their wider angle of coverage. Spotlights are designed to concentrate their light output into a narrower beam, resulting in less overall output than a floodlight. However, spotlights are capable of producing a higher intensity beam at the expense of overall light output.

Light Distribution:

Floodlights provide more indirect lighting, illuminating larger spaces evenly. Spotlights cast a narrow beam of light onto a specific area, producing a concentrated beam with little to no spillage around it.

Visual effect:

Floodlights produce a more diffuse and soft lighting effect, suitable for applications requiring even lighting. Spotlights produce a more dramatic and intense lighting effect, ideal for applications that require directional lighting to draw attention to a specific object or area.

In addition to the differences in lighting effects between floodlight and spotlight LED fixtures, there are other major differences including application use, light output, ease of installation, cost, and more. It is important to understand these differences when choosing the right type of LED fixture for your specific application and lighting requirements.

Application

Floodlight LED It projects a wide beam of light over a large area, illuminating a vast space with a high degree of uniformity. However, due to its large size and weight, it is not suitable for installation in small spaces or high ceilings.

Floodlights are often used for general area lighting tasks such as lighting large open spaces such as warehouses, stadiums or outdoor areas. Spotlights are better suited for highlighting specific objects or areas, such as artwork, signage, or stage lighting effects.

Installation Requirements

Floodlights often require less precise aiming and can be installed in different locations to illuminate different areas of a space. Spotlights require precise aiming to ensure the beam is directed to the desired object or area, making installation more challenging.

Cost

Generally speaking, floodlights are less expensive than spotlights because they cover a wider angle and are able to illuminate a larger space with a single fixture. Spotlights require multiple lamps to achieve the same visual effect, resulting in higher overall costs.

In summary, floodlights and spotlights each have unique advantages and disadvantages that make them suitable for different applications and lighting requirements. When choosing the right type of LED fixture, it is important to consider your specific application needs to ensure a successful implementation and achieve the desired lighting effects.

What is the status of the advanced packaging industry 2023?

queendomlamp — Wed, 06 Sep 2023 06:06:57 +0000

What is the status of the advanced packaging industry 2023?

The semi-annual “transcripts” of 11 LED packaging listed companies revealed their clues. Only 3 companies including Mulinsen, Zhaochi, and Queendom achieved double profits, while 3 companies including Wanrun Technology, Ruifeng Optoelectronics, and Changfang Group did not. Net profit was negative.

Especially in the first quarter of this year, it has been evaluated by many LED industry professionals as the “darkest” Q1 ever. There are very few LED packaging listed companies that can achieve double growth in profits.

Since entering the second quarter, the LED industry has gradually recovered and the market demand for LED applications has recovered significantly. In the first half of this year, a number of listed LED lighting and LED display companies achieved good results against the trend.

Where is the “miserable” LED package?

Under the influence of domestic and foreign macro factors, the rapid growth of the global economy has encountered obstacles, and the balance of supply and demand of products in various industries around the world has undergone certain changes. Coupled with the domestic economy turning to high-quality development, all industries are facing certain pressures and challenges in the short term.

Among them, the pressure on the LED packaging industry is particularly obvious. Especially on the backlight and display side, although the downstream demand keeps growing, due to the sluggish demand last year and the backlog of inventory, the transmission to the midstream and upstream is relatively slow, and the recovery speed is not as fast as expected.

As the largest LED packaging manufacturer in China, Mulinsen achieved a 10.55% growth in its “LEDVANCE” brand in the first half of this year, but its “Mulinsen” brand revenue was only 2.867 billion yuan, a year-on-year decline of 9.6%.

Affected by the shrinking consumer demand in the market, Hongli Zhihui’s LED semiconductor packaging business revenue in the first half of this year was 1.336 billion yuan, a 7.23% decline from last year. To this end, Hongli Zhihui will continue to consolidate the strategic foundation of the LED semiconductor packaging business, leverage the Mini LED project to achieve a breakthrough in the sector, and comprehensively enhance its competitiveness and influence in the LED segment.

In the face of fierce market competition, Wanrun Technology’s net profit continued to suffer losses, but the loss range narrowed by 83.85% year-on-year. Similarly, Refond Optoelectronics’ display LED business and lighting LED business sales have both declined, and net profit has also turned from profit to loss.

At the end of December 2022, after Changfang Group’s light source packaging business moved to Nanchang, it was basically in the state of commissioning and trial production in the first half of this year, which affected order delivery and led to a decline in revenue. In addition, after the comprehensive strengthening of Kang Mingsheng’s management and control on August 8, 2022, production and operation were disrupted by the obstruction of Kang Mingsheng’s original management team. In the first half of 2023, customers and suppliers are still in the recovery period, and production orders and material supply are affected to a certain extent. It also leads to a drop in income.

Where is the “outlet” for LED packaging?

Against the backdrop of a downturn in the general environment, how to develop with high quality has returned to the most important issue for enterprises at present.

In the past two years, the packaging capacity of traditional lighting LED devices with a large area and wide range has been overcapacity, and the packaging production capacity has been concentrated to leading manufacturers, which shows that the market concentration in the LED packaging field will further increase.

At the same time, leaders in the packaging industry have deployed niche markets one after another, and Queendom has strengthened its channel layout and continued to cultivate and develop around future market growth points such as Mini/Micro-LED new displays, smart lighting, outdoor lighting, and automotive lighting.

The healthy competition of car manufacturers has spawned AR-HUD, smart car lights, and digital headlights. , car display, car ambient light and many other car LED application scenarios.

In the field of Mini/Micro LED, the application scenarios of Mini LED continue to expand, the commercialization process is accelerated, and consumer-side application products continue to emerge. Application terminals cover TVs, monitors, car screens, commercial display screens, medical screens, notebooks, etc. Queendom Micro LED has also successfully cut into the display of AR devices by virtue of its advantages in brightness and reliability.

Especially in the field of vehicle display, the broad market prospect has attracted many LED packaging manufacturers such as Queendom, Dongshan Precision, Nationstar Optoelectronics, Hongli Zhihui, Jinko Electronics, Jingtai, Jufei Optoelectronics, Refond Optoelectronics, etc. , and achieved remarkable results.

It is understood that Nationstar Optoelectronics’ in-vehicle Mini LED backlight display is carrying out sample certification with customers; Jinko Electronics has launched a variety of car-grade LED devices and modules; The third-generation SAIC Roewe RX5 and other cars; Queendom’s Mini LED products and technical solutions have also cooperated with many customers for verification.

In addition, in the field of high-end lighting such as plant lighting and health lighting, LED packaging manufacturers such as Queendom, Nationstar Optoelectronics, Hongli Zhihui, and Xuyu Optoelectronics have also achieved good results.

“Price rising tide” ushered in an inflection point

Since May, LED packaging manufacturers have sent out price hike signals one after another, and the LED packaging industry has finally ushered in a dawn.

Queendom LED has noticed that many packaging manufacturers including Dongshan Precision, Mulinsen, Ruisheng Optoelectronics, and Zhaochi Guangyuan have successively adjusted prices since May, and some manufacturers even raised prices twice in just over a month. The price increase is basically around 10%.

In the few days since September, Mulinsen, Dongshan Precision, Ruisheng Optoelectronics, Shanxi Xingxin Semiconductor and other companies have issued price adjustment notices again. The current round of price increases ranges from 5-15%, and the coverage of price adjustment products has also expanded. .

Indeed, the improvement in inventory and the urgency to make profits after the continuous price war have supported the price increases of RGB packaging companies and LED display manufacturers.

And rounds of price increases have also pushed the LED industry to usher in an inflection point. At present, the inventory of the entire industry chain is returning to the normal “water level” or even lower than its average level, and some enterprises have begun to replenish inventory. Especially on the LED packaging side, some production lines that were shut down at the end of last year and early this year began to resume operation.

It is worth noting that the current price increase of RGB packaging is also based on the production reduction since last year, and even after multiple price adjustments, the current price is still far from that in 2021.

“The production capacity that was reduced last year has not yet been reopened.” A salesperson from a major RGB packaging factory told Gaogong LED that the current market situation can only be said to have barely returned to a relatively normal level.

GGII analysis believes that in order to truly resolve overcapacity, the first step is to speed up the application of downstream display applications in various market segments; at the same time, packaging companies must also strengthen self-discipline, actively control the pace of production, and make up their minds to truly reduce production. Products must resolutely reduce production.

In general, in the future, with the increasing volume of the Mini/Micro LED market and the significant growth of high-end segment markets such as automotive LED, plant lighting, and health lighting, it is expected to drive a steady increase in the output value of LED packaging.
