| 1879年，爱迪生发明第一盏白炽灯（碳丝白炽灯），开始了人类第一次照明光源技术革命。白炽灯使用寿命短，光效低，但显色度高。 In 1879, Edison invented the first incandescent lamp (carbon filament incandescent lamp) and began the first technological revolution of lighting source. Incandescent lamp has short service life, low light efficiency, but high chroma. 第二代照明光源是卤素灯，所发出的光强度远远高出白炽灯，而能耗约降低三分之一。 The second generation lighting source is halogen lamp, which emits much higher light intensity than incandescent lamp and reduces energy consumption by about one third. 金卤灯因灯泡中填充了金属卤化物而得名，基本构造与发光原理大致与荧光灯管相似，不同之处在于弧光放电点灯，产生高热，金属卤化物升华成为蒸气，直接发出可见光，节能80％至90％，属第三代照明光源。 Metal halide lamp is named for filling metal halide in the bulb. Its basic structure and luminous principle are similar to fluorescent lamp tube. The difference is that arc discharge lamp generates high heat. Metal halide sublimates into vapor, emits visible light directly, saves 80% to 90% energy, and belongs to the third generation lighting source. 金卤灯是继白炽灯、卤素灯之后当今世界崛起的第三代绿色照明光源，以光效高、显色性好、使用寿命长等优势，不仅成为高档轿车、背投电视等光源的首选，还可广泛应用于军事、探险、水下作业、野外搜救等领域。与普通白炽灯相比，金卤灯节能效果惊人，市场空间巨大。目前，金卤灯在欧美发达国家发展势头迅猛，已有近40％的普及率。但我国去年80亿支灯泡产量中，金卤灯比例不到2％。由于功率越小，技术要求越高，目前国内50W以下的金卤灯生产尚属空白。 Metal halide lamp is the third generation green lighting source rising in the world after incandescent lamp and halogen lamp. With the advantages of high light efficiency, good color rendering and long service life, it not only becomes the first choice for high-end cars, back-projection TV and other light sources, but also can be widely used in military, exploration, underwater operation, field search and rescue and other fields. Compared with ordinary incandescent lamp, metal halide lamp has amazing energy-saving effect and huge market space. At present, metal halide lamps are developing rapidly in developed countries in Europe and the United States, with a penetration rate of nearly 40%. However, of the 8 billion bulbs produced in China last year, the proportion of metal halide lamps was less than 2%. Due to the lower power and higher technical requirements, the production of metal halide lamps under 50W is still blank in China. |
