J2501型光具盘平行光源的设计,是沿用66年前的产品,只将光源筒的直径由100毫米增大到114毫米.原结构为封闭式,散热困难,极易损坏光源灯泡.以前产品的灯泡功率是15瓦,现行标准改为45瓦,灯泡功率的提高,原光源的设计缺点更加突出,有时甚至使灯泡后部接点的焊锡熔化,造成电路短路,为此我们进行了改进. The J2501 optical disk parallel light source design is based on the product of 66 years ago. It only increases the diameter of the light source tube from 100 mm to 114 mm. The original structure is closed, heat dissipation is difficult, and the light source bulb is easily damaged. The lamp power is 15 watts, the current standard is changed to 45 watts, the lamp power is increased, the original light source design flaws are even more prominent, and sometimes even the solder on the back of the lamp bulb melts, causing a short circuit. For this reason, we have made improvements.
