Yesterday, Chen Daoman, the chief engineer of Kaikai Lighting Co., Ltd., looked at the ceramic liner on the enamel production line. After surface treatment, component assembly, and two-head sealing and exhausting, until the end of a complete lamp, his heart filled with joy: This batch of ceramic metal halide lamps went smoothly off the assembly line. “Kaikai Lighting†has developed a low-power ceramic metal halide lamp in 4 years and entered the stage of small batch production. This invention not only fills the domestic gap, but also breaks the monopoly pattern of foreign manufacturers in one fell swoop, and has become one of the few manufacturers in the world that can produce such lamps.
Previously, high-pressure sodium lamps and quartz metal lamps were commonly used in China. Both have advantages and disadvantages. High-pressure sodium lamps have poor color rendering. Quartz metal lamps are susceptible to reaction with metal halides due to quartz, and the color stability is not strong. Halogen lamps can overcome these two shortcomings at the same time, and combine their advantages in one: high luminous efficiency, good color rendering properties, and a certain life expectancy, the market prospects are promising. In foreign countries, the research and development of ceramic metal halide lamps began in the mid-1990s. Before the successful development of “Kai Kaiâ€, only foreign famous companies such as Philips, GE, Osram, and Panasonic could produce. Rely on imports.
In 2002, “Kaikai Lighting†began to raise various tasks for the development of ceramic metal halide lamps. After the lamp type was produced in 2004, the process conditions were continuously improved, the process equipment was increased, and various characteristic experiments were carried out. It was officially put into operation in July 2006. . Referring to foreign samples of similar products, the actual measurement shows that the performance of ceramic metal halide lamps produced by Kaikai has approached or reached the international advanced level.
The core technology of ceramic metal halide lamps lies in the manufacture of ceramic tubes - ceramic tubes. In order to successfully develop this part, the company has set up a factory in cooperation with Shenyang Glass Research Institute to develop and produce ceramic tubes. The ceramic tube shall be made into a translucent shape, a large intermediate shape, and a small irregular shape at both ends, and shall withstand the corrosion of the metal halide. Since halides are easily oxidized in air, both development and production processes must be carried out under near-vacuum conditions, with only one part per million of oxygen and water in the air. The electrode in the lamp is not simple to manufacture. It is necessary to use a delicate process to take out the extremely thin filament from the glass tube, and then solder and seal the electrode assembly. The material used for the electrode must be resistant to halide corrosion at high temperature. The operating temperature of this process is basically Above 4000 degrees Celsius.
The successful creation of “Kai Kai†made it quickly attract the market, and it only took 3 months to put into production, and the order was coming. According to reports, the company currently produces 800 ceramics per year with an annual output of more than 200,000 ceramic metal halide lamps. It is expected that 2 million production units will be produced next year. In the future, it will take 2-3 years to form an annual production capacity of 500. Ten thousand, sales revenue reached 400 million yuan.
