隨著LED發光效能(流明/瓦)的持續（xù）改善和價格不斷下降，LED正在驅動一些新的照明應用。今天，高亮度LED在一些適合通用照明的（de）應用中正變得越來越普遍，如閃光燈，園林/景（jǐng）觀照明和小型閱讀燈。
專業室內照明產品，像畫像燈（dēng）光照明等（děng）也開始結合（hé）無（wú）線、電池供電、高光通量LED燈具（jù）。LED在（zài）室（shì）內照明係統的優勢是照明裝置可以很容易地安裝在牆上無需任何昂貴的布線。 LED的也越來越（yuè）多地被考慮（lǜ）其他各種專業照明應用，如外科手術燈，機器視覺，軍事照明及演唱會的燈光。
在許多情況下， LED在現有（yǒu）的（de）應用中開始取代熒光燈（dēng）和白熾燈。這是因（yīn）為LED隻從裝置的前端發光（guāng），因此一個60-70 lm /W的LED燈可以媲美傳統的100 lm /W全方位熒（yíng）光燈。
主流（liú）的通用照明包括企業照明和消費者的家庭照明。高（gāo）光通量的LED最終的潛在市場是針對數十億美元的室內和室外的家庭以（yǐ）及企業通用照明市場開發（fā）具有成本（běn）效益的白（bái）光（guāng）照明解決方案。
根（gēn）據iSuppli統計，2006年全球通（tōng）用照明燈具市場達到約170美元億元。此外，2006年全球照明配件市場約在30億美元左右。
通用照明市場固態照明的潛在優勢有：
減少能源消耗：各種研究機構的研究都和美國（guó）能源部指出的（de）一（yī）樣，住宅照明占（zhàn）到全球能耗的25%到30%之間。LED是比現有的白熾燈和熒光燈更高效的照明解決方案，並且在燈（dēng）泡的整（zhěng）個（gè）壽命期節省大量的（de）能源。據估計，用LED燈代替100萬隻白熾（chì）燈可節（jiē）約230kmW/h或每年約2500萬美元（yuán）(以單價（jià）0.11/kwh計（jì）算)。 更高的可靠性：LED比其他光源更可靠，LED燈泡壽命是（shì）白熾燈泡（pào）的40倍。相比緊湊型熒光（guāng）燈(CFL)不含有汙染的（de）汞。 更高的設計靈活性。
不（bú）過，為了成功地打入主流市場，例如住宅和企（qǐ）業的通（tōng）用照明應用，LED必（bì）須在成本和性（xìng）能的基礎上與現有的白熾燈和熒光燈（dēng）照明技（jì）術競爭。目前（qián），LED燈（dēng）前期成本以流（liú）明1美元計算大大高於大多數通用照明用的常規燈（dēng）。 iSuppli估計，目前LED燈泡作為通用照明的初步費用至少是熒光燈的25倍。為了成功進入這一市場，需要在功率轉換（huàn）效率、顏色指數和光輸出和（hé）成本比（bǐ）例（lì）(采用$/lm計算)等（děng）方麵（miàn）進（jìn）行改善。
With LED luminous efficiency (lumens / watt) continued to improve and prices continue to decline, LED is driving some new lighting applications. Today, high brightness LEDs are becoming more common in applications suitable for general lighting, such as flash, landscape / landscape lighting and small reading lights.
Professional indoor lighting products, such as portrait lighting also began to combine wireless, battery-powered, high luminous flux LED lamps. The advantage of LED in an indoor lighting system is that the lighting device can be easily installed on the wall without any expensive wiring. LEDs are also increasingly being considered for a variety of other professional lighting applications such as surgical lights, machine vision, military lighting and concert lighting.
In many cases, LEDs have begun to replace fluorescent and incandescent lamps in existing applications. This is because the LED only from the front of the device light, so a 60-70 lm / W LED lights can be comparable to the traditional 100 lm / W full range of fluorescent lamps.
Mainstream general lighting includes corporate lighting and consumer home lighting. The final potential market for high luminous flux LEDs is a cost-effective white lighting solution for billions of dollars of indoor and outdoor homes as well as enterprise general lighting markets.
According to iSuppli statistics, in 2006 the global general lighting market reached about 170 billion yuan. In addition, the global lighting accessories market in 2006 about 30 billion US dollars.
General lighting market, the potential advantages of solid-state lighting are:
Reduce energy consumption: Various research institutions and research are pointed out by the US Department of Energy, residential lighting accounts for 25% to 30% of global energy consumption. LEDs are more efficient lighting solutions than existing incandescent and fluorescent lamps, and save a lot of energy throughout the life of the lamp. It is estimated that the use of LED lights instead of 1 million incandescent lamps can save 230kmW / h or about 25 million US dollars per year (priced at 0.11 / kwh). Higher reliability: LED is more reliable than other light sources, LED bulb life is 40 times the incandescent bulb. Compared to compact fluorescent lamps (CFL) does not contain contaminated mercury. Higher design flexibility.
However, in order to successfully enter the mainstream market, such as residential and corporate general lighting applications, LED must be based on cost and performance with existing incandescent and fluorescent lighting technology competition. At present, the pre-cost of LED lights to lumens 1 US dollars is much higher than most of the general lighting with conventional lights. ISuppli estimates that the current cost of LED bulbs as general lighting is at least 25 times that of fluorescent lamps. In order to successfully enter this market, the need for power conversion efficiency, color index and light output and cost ratio (using $ / lm calculation) and other aspects of improvement.
