灯与我们的生活密不可分。在我们的生活中,各种灯饰的出现给人们的生活带来了许多便利。在各类照明产品中,led灯珠和贴片这两种照明产品都吸引了消费者的目光。对于这两种不同的照明类型,它们之间的主要区别是什么?爱游戏ayxdota2

我们先来看看LED灯珠有哪些特点?LED灯珠的角度很小。光相对集中,射程远,但照射范围有限;而LED贴片的一般角度非常大。属于光相对散射,照射范围较广,但照射范围相对较短。LED灯珠用于放电发光,而LED贴片用于冷发光。

相比之下,SMD有什么优势?爱游戏ayxapp也是一种LED灯珠。普通的LED有两个或四个管脚,有些没有管脚形状的管脚,它们焊接在电路板的铜箔附近。选择灯珠的关键是考虑色温、显色指数、发光效率、发光衰减和电源质量。

它们之间有什么区别?LED灯珠有多种形式,主要是考虑到各种功耗形式而配制的。

The advantages and disadvantages of each  

For led lamp beads, what is its advantage? The shape of cob led lamp beads in LED lamps has undergone direct insertion and patching. With technological progress, it is logical that multiple LED light-emitting chips are highly integrated and directly packaged in On the substrate (integrated design of circuit and heat dissipation), a compact, high-power, ultra-high-power LED light-emitting element is formed, which is "COB".  

至于补丁,它的优点是什么?集成LED在市场上一般是COB光源的另一个名称,但实际上COB光源的特性还不能很清楚的描述。COB是指板上芯片,它直接将低功耗芯片封装在铝基板上,以快速散热。芯片面积小,散热效率高,驱动电流小。因此,它具有低热阻、高导热性和高散热性。与普通SMD相比,低功率光源具有亮度高、热阻低的特点。

If the light is on, it means that the lamp bead is basically functional. If it does not light up, exchange the red and black test leads, and test again. In order to avoid the cathode and anode of some lamp beads are opposite to the general ones. The lamp bead lights up to observe the color of the lamp bead and whether the color temperature meets the requirements. Whether the brightness is appropriate. Choose suitable lamp beads. Therefore, we found that both of them have their own advantages.  

总之,LED灯珠和贴片各有优势。当您有兴趣购买灯饰时,可以根据自己的选择购买不同款式、不同类型的产品。说起LED灯珠和贴片,它们的使用范围是不一样的。在这个时候,每个人都可以根据自己的需要进行选择。爱游戏ayxdota2
