LED lighting is in the early stages of explosive growth
Although we often see new LED applications every once in a while, LED general lighting applications seem to be perfect. Of course, there is room for improvement in terms of brightness and efficiency, but in terms of the big picture, is LED really the highest level in addition to commercial and special effect lighting? Jordon Papanier, marketing manager at LEDtronics, said there should be no fundamental design breakthroughs in the foreseeable future. Before we can have a common LED indoor bulb that meets the standard A19 bulb package size, the wattage required per lumen still needs further improvement. He said. On the other hand, IreneSignorino, director of marketing for the lighting and automotive products division at Microsemi, is optimistic. She said: In general, the LED lighting market is undoubtedly still in the cultivation stage. Although there are some special LED applications that are already in the mature stage of industry analysts, most LED lighting markets are still a market full of many open possibilities. We still have a lot of work to do before the LEDs reach their highest level. Most LED bulbs today offer consumers a similar experience to incandescent lamps in terms of luminous flux and color quality, and consume much less power. This is enough to cause consumers to be interested in LED lighting. However, there is still room for improvement. Peter DiMaso, director of strategic marketing for TI's Lighting Power Products Division, said. In addition to simple light bulb replacement, key design breakthroughs in LED bulbs include cost-effective ways to add communication and intelligence features such as smart in-position detection, color adjustment, remote control, and wireless or wired access via the Internet. Technology, etc. DiMaso said. Therefore, we have not reached the highest level of development in the field of LED solid-state lighting (SSL), and there is still room for improvement and innovation. When people mention SSL, they always think of LEDs and are just a single component. Makarand Chipalkatti, senior director of solid-state lighting and emerging markets at Osram Sylvania, pointed out. In the total LED lighting system, there is still a lot of work to be done, including optical, architectural integration, power distribution, control and communication, and the most critical is the human factor. To understand that the lighting system is not just a light bulb, the key is light output. . Chipalkatti reminded. We are in the early stages of the explosive growth of LED general lighting, and Tony Carrella, president of Tranxon Technologies and Lighting Control, said that LED consumer products are continuously improving, that is, lumens per watt, CRI (staining index), cost and direct replacement will be very May become the most active area. SSL development barriers LED lighting is more efficient, so it can reduce electricity bills. Since LEDs have a long life, they are cheaper to operate over a long period of time. SSL can achieve the brightness of traditional incandescent and cold cathode fluorescent (CCF) illumination, even higher, and can be dimmed. So, what are the biggest obstacles for most consumers to turn to full LED lighting? Almost everyone agrees that cost is the biggest obstacle to the popularity of SSL. LED lighting is not cheap. The main obstacle for most consumers is price. Heather Goldsmith, global marketing communications manager at FutureLightingSolutions, believes that consumers are reluctant to spend $20 to $30 on LED lights in the case of traditional light bulbs for a few dollars. Even with high electricity bills, most consumers are reluctant to make initial cost investments in LED lighting. In addition to price, there are other factors that are hindering the development of SSL technology. The biggest obstacle for most consumers is undoubtedly the price. Mike Kretzmer, new business development manager at ERGLighting, said, however, that there is a lack of standardization and doubts about the quality of early products. Even more terrible is the fact that LEDs are electronic products, and lighting has always been in the electrical field, which creates considerable educational barriers between the design of lamps and the purchase of lamps. The main problem is always the fact that any LED bulb replacement is inevitably much more expensive than a replacement bulb. Peter B. Green, LED division manager of International Rectifier, said. Other impediments relate to light source performance compared to light bulbs, including dimming capability, color temperature, or whiteness of LED emission, relative illuminance of the bulb, and whether light is efficiently and evenly distributed, and does not produce darkness. Zone or strange pattern. He pointed out. The barrier to LED popularity that is often mentioned is the price. Consumers also have a discarding mentality, and they want to buy better light sources at the same price as incandescent lamps and CFLs (compact fluorescent lamps). Matt Reynolds, application engineer for the National Semiconductor Corporation's SSL business unit, said. Consumers have a hard time understanding the benefits of SSL and longevity. In general, they still don't understand what LED lighting can offer. Reynolds adds that cultivating public awareness and ensuring that we don't fall into the CFL trap (an unreliable and poor source of light) will be key, and evidence of reliability and good returns needs to be demonstrated. In addition to cost, Optek's visible LED product engineer Daniel Jacobs offers other possible sources of obstacles. Knowledge can also be said to be a bit of a hindrance because consumers are generally not familiar with SSL technology. He pointed out that the feeling of error is also a problem. Cheap and low-performance products have entered the market and have damaged the reputation of LEDs. For example, LED traffic lights are one of the most significant LED applications, but reliability is very poor. Summarizing the views of LED manufacturers, the biggest obstacles to SSL are price, consumer awareness and education, and evidence of reliability. If a solution to these problems is under development, then when can we see LEDs being widely used? LED lighting has been around for a long time, and how can we promote SSL into every home? Maybe a little bit of strong government support, like the Federal Communications Commission’s mandate to promote digital TV to the public? When can LEDs be used as the main source of light? My feeling is that without the government's enforcement or promotion, the popularity of SSL lighting will be very slow, and it may take 10 to 20 years to reach full replacement. BrettShriver, director of sales at GlobalLighting Technologies, said.
