| 美标金卤灯和欧标金卤灯的镇流器不同，欧标金卤灯可用钠灯线路或汞灯线路，即可用电感镇流器加触发器；而美标金卤灯则应配置专用的CWA镇流器，即超前顶峰式（漏磁升压式）镇流器，否则将导致启动困难，降低光效，使色温不稳定，降低灯泡寿命。 The ballast of American standard metal halide lamp is different from that of European standard metal halide lamp. European standard metal halide lamp can use sodium lamp circuit or mercury lamp circuit, i.e. inductance ballast plus trigger; while American standard metal halide lamp should be equipped with special CWA ballast, i.e. advanced peak type (magnetic leakage boost type) ballast, otherwise it will lead to difficulty in starting up, reduce light efficiency and make it easier to operate. The color temperature is unstable, reducing the lamp life. 欧标金卤灯只要配上汞灯镇流器或高压钠灯镇流器加触发器及补偿电容器在我国220V 50Hz电网上可以可靠工作。欧标金卤灯根据启动脉冲峰值电压的不同，可分为两种启动脉冲幅值为0.6KV-1.5KV如HPI灯，另一种4.0KV-5.0KV如HQI-T金卤灯。美标金卤灯就不能用欧标金卤灯的电器配置，欧标金卤灯电路中灯获得的最低启动有效值电压（≤240V）不能满足美标金卤灯中灯对电器的要求，所以美标的金卤灯泡必须用CWA的点灯电路配置（镇流器为LC顶峰超前式漏磁升压镇流器，输出电压有效值和波形因子可以满足灯的要求），才能保证灯泡正常工作。 Euro-standard metal halide lamp can work reliably on 220V 50Hz power grid in China as long as it is equipped with mercury lamp ballast or high voltage sodium lamp ballast plus trigger and compensation capacitor. According to the difference of peak voltage of starting pulse, Eurostandard metal halide lamp can be divided into two kinds: 0.6KV-1.5KV, such as HPI lamp, and 4.0KV-5.0KV, such as HQI-T metal halide lamp. American standard metal halide lamp can not be equipped with European standard metal halide lamp. The minimum starting effective voltage (<240V) obtained by European standard metal halide lamp circuit can not meet the requirements of American standard metal halide lamp for electrical appliances. Therefore, American standard metal halide lamp must be equipped with CWA lighting circuit (ballast is LC peak leading magnetic leakage booster). Current, RMS of output voltage and waveform factor can meet the requirements of the lamp to ensure the normal operation of the lamp. 如上所述，许多金卤灯配套电器生产厂家和商家，因对各种类型的金卤灯性能不了解，及出于商业利益的需要，仅凭一些简单的试验（用几只灯泡和电器点点，灯泡能亮）就随便配置电器。这样将造就成许多不良后果。以市场上采用欧标电路电路点美标金卤灯为例，将会出现以下几个问题： As mentioned above, many manufacturers and businessmen of metal halide lamp matching electrical appliances, because they do not know the performance of various types of metal halide lamp, and because of the need of commercial interests, configure electrical appliances casually only by some simple tests (light with a few bulbs and electrical appliances, light bulbs). This will lead to many bad consequences. Taking the European standard circuit as the example, the following problems will appear: 1、容易烧坏灯泡 1. Burn the bulb easily. 因美标灯内管有触发极，当灯点到正常高亮度再断电后重新送电，因灯胆气压不能马上启动触发器产生的高压会将灯的触发极和主电极引线烧坏。 Because there is trigger pole in the inner tube of American standard lamp, when the lamp is lit to normal high brightness and then power off, the high voltage generated by the trigger can burn the trigger pole and the main electrode lead of the lamp because the gas pressure of the lamp can not start the trigger immediately. 2、启动困难，严重减短灯寿命 2, start difficulties, reduce the lamp life seriously. 因点灯电路不能满足灯启动的要求，所以有部分灯泡在开始或是灯的寿命期间不能正常启动，表现为灯内胆两电极之间始终在辉光放电，或是几分钟到十几分钟才能启动，象这样灯泡的寿命只有几天到几周，这种情况在灯的启动性能略差的批号中，或电网电压较低的情况下比较常见。 Because the lighting circuit can't satisfy the requirement of light starting, some bulbs can't start normally at the beginning or during the life of the lamp, which means that glow discharge always occurs between the two electrodes in the inner tank of the lamp, or it can only start in a few minutes to ten minutes, so the life of the lamp is only a few days to a few weeks, which is the case when the lamp is turned on. It is quite common for batch numbers with poor dynamic performance or low grid voltage. 3、对灯泡的功率、光效、色温影响较大 3, the power, light efficiency and color temperature of the bulb are greatly affected. 通过相关测试可得出，两种点灯电路功率、光效、色温变化量，在测试中可以看出此电路的变化量要比LC点灯电路大的多。所以说不合理的电器配置不仅损害了用户的利益，造成资源浪费，还影响节能推广应用。 Through relevant tests, it can be concluded that the changes of power, light efficiency and color temperature of the two lighting circuits are much larger than those of LC lighting circuits. Therefore, unreasonable electrical equipment configuration not only damages the interests of users, resulting in waste of resources, but also affects the promotion and application of energy conservation. 为什么会产生上述情况，除了商家、用户对各种金卤灯性能不够了解，灯生产厂家技术服务不到位外，还有一个重要原因就是商业利益和用户追求低价心理。在日常的使用中我们可以对比出用欧标电灯电路配美标灯泡，成套价格是比较低的，所以使的这种配置方式在国内被大量使用。用户追求低价、降低投资成本是无可非议，关键是灯电器厂家和商家要给用户提供价低质优的产品，保证灯能正常工作。 In addition to the lack of understanding of the performance of various metal halide lamps and the inadequate technical services of lamp manufacturers, there is also an important reason for the above-mentioned situation, which is the commercial interests and the psychology of users to pursue low prices. In daily use, we can compare the European standard lamp circuit with the American standard lamp. The price of the complete set is relatively low, so this configuration mode is widely used in China. It is indisputable for users to pursue low price and reduce investment cost. The key is that manufacturers and businessmen of lamp and electrical appliances should provide users with low price, high quality products to ensure that the lamp can work normally. |
