Taiwan LED Street Lighting Standard

In October 2006, the Taiwan region revised and announced CNS10779 road lighting standards. In March 2008, it revised and published the CNS9118 road lighting standard. The Taiwan Institute of Industrial Technology released the “LED Street Lighting Standard” in August 2008. draft). Taiwan’s LED street lamp standard draft has been applied to LED road lighting demonstration, not only to verify the performance of LED street lamp products, but also provide important reference for the amendment of the standard.

Taiwan LED Street Lighting Standard

The main contents of the draft standard for LED street lamps include the scope of application, measurement conditions, specifications and test methods.

(1) Scope of application:

This specification applies to LED street lamps, including power supplies, heat sinks, optical designs, and related mechanical structures.

(2) Measurement conditions

Measurement conditions include temperature (25±2°C), humidity (relative humidity 60±20%), steady state (tested after 60 minutes of lighting), power supply for test (variable range is ±0.5%) and precautions for light intensity measurement .

(3) Specifications

The main contents include insulation resistance, insulation withstand voltage test, dead point lighting, basic characteristics, voltage change rate, temperature cycle, switch test, durability test, humidity switch, surge protection, electromagnetic, dustproof and waterproof, wind tunnel test and vibration test.

Requirements in the basic characteristics: “LED street lamp power factor must be above 0.9, and its power factor test value must be above 95% of the label value, the total circuit power should be within the manufacturer’s label value within ± 110%, the input current harmonic distortion The values ??specified in Table 8 must not be exceeded and the total current harmonic distortion must not exceed 33%.”

What factors need to be considered before the factory lighting decides to use LED?

1. Check the current lighting device’s profile and lumen output. In most cases, installing an LED fixture that is similar to that of the previous fixture will shorten the installation time and speed up the return on investment.

What factors need to be considered before the factory lighting decides to use LED?

2. The number of lumens should be considered less. Compared with lamps using traditional technology, the optical performance of LED lamps tends to increase. In some applications, some fixtures require less lumens than existing fixtures to achieve the desired light level.

3. Understand the regulations. When replacing traditional fixtures, local regulations may require energy conservation and increased lighting control. In addition, many places offer incentives to offset some of the initial costs.

Rising demand for LED filament lamps in the US market in 2018

In recent years, the global lighting market has become increasingly fierce and product differentiation has become an inevitable trend. With the prohibition of the sale of incandescent lamps and the improvement of standardized production specifications of LED filament lamps in recent years, in many lighting fixtures, LED filament lamps have the advantages of their traditional incandescent lamp shapes, full-angle lighting, high color rendering, and high luminous efficacy. The past few years have attracted much attention.

Rising demand for LED filament lamps in the US market in 2018

The demand for filament lamps in the US market soared in 2018. Companies entered the field of filament lamps.

Data showed that in 2015, the global sales of filament lamps exceeded 70 million. In 2016, the global sales of filament lamps exceeded 200 million, and in 2017, the total market capacity of LED filament lamps was 4-5 billion. It is estimated that by 2020, global LED filament lamps will continue to maintain rapid growth.

According to the import trade data, from January to December of 2017, the total export value of LED filament lamps reached 38.13 million US dollars, of which the European market is more receptive to LED filament lamp products, ranking first in export value, up to 22.27 million US dollars, accounting for 58.42%. Followed by 29.44% in North America, 6.05% in Asia, 4.60% in Latin America, 1.24% in Oceania, and 0.25% in Africa.

The European Union plans to completely phase out halogen lamps by 2018 and boost the demand for LED filament lamps in the European market from 2016 to 2017. As the users begin to replace halogen lamps that will be phased out by 2020, the US market is expected to have LED filament lamps. The demand will soar in 2018.

LED bulb prices remain stable

In terms of global LED bulbs, prices remained stable in February 2018. The average retail price of LED bulbs replacing 40-watt incandescent bulbs fell slightly by 0.4% to US$6.3. The retail price of LED bulbs replacing 60-watt incandescent bulbs rose by 0.1% to US$7.5.

LED bulb prices remain stable

From the perspective of regions, prices in the European region have fallen in place of the 40-watt segment, with the German region decreasing by 1.5%. Prices of some early-staged LED filament lamps have dropped significantly. For example, a 4W 420lm filament lamp from Müller is priced at only The US dollar fell by more than 30% to US$2.7, while prices in the UK and Japan and South Korea also declined slightly. Conversely, prices in China and the United States increased slightly, and prices in China’s Taiwan region remained stable.

In lieu of the 60-watt segment, prices in the European region continued to decline, with the German region experiencing the largest drop, reaching 5.1%; the UK region’s prices fell by 0.3%, mainly due to the manufacturers’ low-cost promotions and the withdrawal of some high-priced products from the market; prices in Japan and the United States increased. Prices in other regions remained stable. It is noteworthy that European manufacturers continue to deepen the smart lighting market, such as the 9W 806lm smart light bulb introduced by OSRAM, including a controller, priced at $ 10.9.

Mini LED market is hot

Since the Micro LED has not been used by Apple on the new generation of iWatch, all aspects of its technology and applications have become more rational, and related manufacturers are also actively cooperating with the application.

Mini LED market is hot

At the same time, the Mini LED has gradually entered the reality. From top to bottom, manufacturers have followed suit. After last year’s trial, the major terminal application plants have basically completed the prototype design. From the exhibitions in recent years: Samsung, Lumens and other manufacturers have introduced Mini LED applications.

The market expects 18 years to be the beginning of the large-scale application of Mini LED.

Compared to current conventional applications, Mini LED does have its unique advantages:

For backlight applications, the Mini LED is generally a direct-down design that uses a large number of dense patches to achieve a smaller area of ??dimming. Compared to a traditional backlight design, the Mini LED can be implemented in a smaller light mixing distance. Good brightness uniformity, higher color contrast, and thus achieve ultra-thin, high color rendering, power saving of the end product.

At the same time, because of its design can be used with flexible substrates, with the curved surface of the LCD can also achieve a similar OLED surface display under the condition of ensuring quality, on the other hand, because the current OLED is self-luminous organic materials, in terms of reliability Mini LED It is also very advantageous; based on the mature LED industry chain, the cost of using Mini LED backlight is only about 60% of the same size OLED, which is very competitive in all aspects.

For display applications, the RGB Mini LED overcomes the defect of wire bonding and reliability of the positive-fit chip, and at the same time, it combines the advantages of the COB package to make it possible to further reduce the dot pitch of the display screen. The visual effect of the corresponding terminal product is greatly enhanced, and the viewing distance is also improved. Can be greatly reduced, so that indoor display can further replace the existing LCD market.

On the other hand, the use of RGB Mini LED with a flexible substrate can also achieve a high-quality display of the curved surface. With its self-luminous characteristics, it has a very broad market for some special modeling needs (such as automotive display).

As can be seen from the above, the Mini LED has a great advantage over other competitors in the current situation faced by the LED. Based on this, the various manufacturers are also researching, from the current situation, although the size of the chip and the chip is installed. The small pitch chips are similar but there are many differences.

Its technology has the following characteristics and difficulties:

Judging from the process route, the current Mini LED adopts the flip chip structure, mainly because the flip chip does not need to be wired, which is suitable for the needs of the ultra-small space, and it is also suitable for a variety of materials of the package substrate, and it is precisely because of this, The reliability is also obviously improved, and the maintenance cost of the use of the terminal products is reduced. Therefore, during the actual production process, the control of the flip-chip process is extremely important. At the same time, in the case of a small size, the flatness of the welding surface, the design of the electrode structure, and the ease of welding. The adaptability of the welding parameters and the latitude of the package are the difficulties and focuses of its design.

For the backlight application of Mini LED, due to the ultra-thin terminal requirements, combined with the cost and control difficulties, the chip can be achieved in a wider range of LED chip spacing to achieve a smaller light mixing distance, and then reduce the thickness of the whole machine, so how Implementing the light emission control of the chip and the consistency in the later use process are the key points.

For display applications using RGB Mini LEDs, the brightness concentration required for conventional small-pitch chips, the brightness consistency at low currents, and the low and consistent capacitance characteristics are eliminated. The use environment and post-maintenance require higher requirements for reliability. It is the red light chip that needs to carry out the substrate transfer during the process of manufacturing flip-chips. The overall process is more complicated, and the transfer technology, production yield control, and reliability during use are the key considerations.

Due to the small size of the Mini LED chip and the requirement for consistency of light color, the Mini LED is currently used in an all-in-ones mode. The operating efficiency is low. If the number of products is expected to increase with the market, the application needs to be in a single product. When working on a chip with more than one hundred kilowatts, the efficiency limit is more obvious. Therefore, how to cooperate with the application side and effectively improve the operating efficiency is also the current focus.

Tottenham Stadium will use LED lighting

A few days ago, Tottenham Hotspur of the English Premier League club decided to use LED lighting in its competition venues and venues. It is reported that the venue can accommodate 61,559 seats.

Tottenham Stadium will use LED lighting

LED goes into the Premier League: Tottenham Stadium will use LED lighting

The Spurs updated their latest information on the stadium’s roof structure on its official website.

“The roof was installed with 324 LED sports lights that provide flood lighting for the venue.”

However, the Spurs declined to disclose their LED lighting suppliers.

“Once all matters have been finalized, we will announce the lighting supplier in due course.” “Before this, we cannot disclose which one is.”

Last summer, the Spurs announced that Austrian LED lighting manufacturer Zumtobel is their lighting partner. The project is worth 850 million pounds (about 7.423 billion RMB). It focuses on the “fan experience” of digital lighting. . However, the project does not include site lighting.

At that time, the team did not even promise to use LED lighting. Although LED stadium lighting is emerging in many professional sports venues (such as Major League Baseball and NFL stadiums), stadium operators are sometimes opting to upgrade non-LED lighting systems. It is unclear whether Zumtobel won the bid for venue lighting.

The 324-inch LED luminaires will be mounted on 54 roof pillars, each with 6 inches. The roof is made up of glass panels that can be angled on the stands, but keep the playing field open.

The Spurs hope to open the stadium before the start of the 2018 season in August. A National Football League match between the Auckland Commando and the Seattle Seahawks will be held on October 14.

China’s low-cost LED products swept the Korean lighting market

According to a report from Korean media MoneyToday, recently the LED lighting industry and the Korean Photonics Industry Promotion Association (KAPID) reported that the Korean LED lighting market certified in 2015 was about 1 trillion won (approximately US$850 million). Over the years, the LED lighting market has maintained a growth rate of 10-15%, but now it is due to oversupply, and it has hit a low-price bloody battle.

China's low-cost LED products swept the Korean lighting market

At the beginning of 2015, the Korean Commission for Corporate Partnership excluded the LED lighting industry, which is suitable for small and medium-sized enterprises, in order to encourage large companies to invest in non-governmental LED lighting markets other than government procurement projects. Joint competition to stimulate the growth of the LED market.

However, the situation was unexpected. What emerged in the market was not the competition between South Korean SMEs but the low-priced products in China that gradually swept the market.

According to data from the Korea Optical Industry Promotion Association, LED lighting was still suitable for SMEs in 2013. The private market is about 500 billion won, of which 99% is estimated to be produced in China.

According to industry figures, in the government procurement market of 300 billion won, LED was still limited to the competitive area of ??small and medium-sized enterprises, and it can maintain 100% production in South Korea. However, in the private market, whether it is B2B or B2C, almost all of China’s LED products are in the world.

Recently, a report published by the Korea Consumer Protection Institute (KCA) also pointed out that according to sales volume and visibility, 17 out of the 19 LED lighting products in Korea are produced in China by OEM and ODM.

According to the analysis, although LED has been lifted from the suitable industry, South Korean companies are still eager to import low-priced land-based products, mainly because there is no confidence in the LED market. LED lighting industry sources said that large companies are competing to import low-priced Chinese products, mainly to make up for the loss of the LED lighting business unit before, to increase profitability.

However, with the growing threat of low prices in China, the phenomenon at this time is that more and more SMEs have abandoned self-development of LED modules. People in the industry believe that South Korean SMEs have not yet reached the mass production stage after self-developed model organizations. The decree specifying suitable industry species was lifted, leaving SMEs facing the need to compete with large companies for the low price of Chinese products imported, leading to SMEs’ ??competition. The industry has given up on the development of original technologies. It is unclear whether the Korean government’s LED lighting policy will change in the future.
