Future LED bulb replacement market grows fastest

According to the latest analysis report from the market research firm StrategiesUnlimited, although the LED bulb replacement market in 2009 is still very small, it has now become the fastest growing application market. The CAGR (the compound annual growth rate) will reach 104.2% in the next four years. LED bulbs The replacement revenue will exceed the revenue of the LED architectural lighting market for the first time in 2011. In addition to these two major markets, the residential LED lighting market will continue to grow during the period from 2010 to 2014, and the CAGR will reach 71.8%. During this period, the growth rate of retail display, off-grid and outdoor LED lighting application market is also expected to exceed 40%.

Dr. Markus Klein, General Manager of Osram Solid-State Lighting Division, stated: “The growth momentum of the LED bulb replacement market is mainly driven by the lighting efficiency regulations implemented by countries around the world.”

With the successive implementation of global incandescent lamp banned regulations, existing incandescent lamps will be replaced with CFL energy-saving lamps or LED bulbs. Currently, the cost of LED chips is still high and the heat dissipation problem has not yet been completely resolved. Therefore, CFL energy-saving lamps have a large market growth space in the next five years, but with the continuous decrease in the manufacturing cost of LED chips and CFL energy-saving lamps. There are still environmental pollution problems, so LED bulbs will gradually become the mainstream of market demand after 5 years. At present, the replacement market for LED bulbs mainly includes: fluorescent lamps, spotlights, work lights, shelf lights, and downlights in homes, offices, and shops.

At present, the efficiency of LED lighting fixtures is generally only 70-85%. To improve this efficiency, there are only two methods. One is to increase the luminous efficiency of LED chips, and the Other is to increase the beam angle of LED chips. OSRAM has recently introduced the industry's first OSLON SSL150 with a new 150-degree beam angle. The wide beam angle feature reduces light loss for retroreflective systems, which means that LED lamps designed with the OSLON SSL150 can be made more efficient and simpler. . Dr. MarkusKlein pointed out: "At present, the beam angle of LED chips in the industry is usually only 120 degrees."

The uniform light distribution of the new OSLON SSL150 allows designers to better manage the light of external reflectors, especially when designing LED bulbs and downlights. In addition, the small size of the OSLON SSL150 simplifies the design of lamps and light sets and facilitates miniaturization.

Dr. MarkusKlein said: "The new OSLON SSL150 has a compact design, compact and compact, so even if they are densely arranged together will not produce a shadow effect. Take the reflector application as an example, the lamp efficiency can be increased by more than 5%. Reflector can also be achieved The miniaturized design, and the depth of installation of the luminaire itself, are also shallow. With these features, this LED offers a flexible design option for high-performance lighting solutions."

The OSLONSSL150 is also an excellent source of light for other applications such as diffuse lighting suspended from the ceiling and wide-area backlighting with no visible light spots. In addition, diffusers used for LED lamps/modification lamps that simulate incandescent and halogen lamps can also provide uniform light. Also, color mixing is easier than ever. If a group of OSLON SSL LEDs of different colors are used, the color mixing effect at the reflector level can be achieved, which is much simpler than the color mixing through the auxiliary lens.

From the technical data point of view, the new LED is also quite outstanding. The LED is based on a 1 square millimeter chip, which produces a typical brightness of 92 lumens (lm) at a working current of 350 mA, a color temperature of 3000 K, and a brightness of 156 lm at an operating current of 700 mA. It offers all white tones (2700-6500K) and different color versions. OSLONSSL150 is a new member of the OSLONSSL product family (the beam angle of other products in the series is 80 degrees), and the dimensions of 3mm×3mm fully comply with the characteristics of the product portfolio.
