玻璃灯罩的好处：
The benefits of glass lampshade:
灯罩具有透光性好、高温无气体发挥、不泛黄、耐候性、透光率高、方便清洁、美观等优点，可选用内外涂、磨砂、真空镀膜、磨砂镀铝、静电喷涂、喷色等着色工艺。适宜室内装饰、照明用灯。现目前优质LED室内灯具均已采用玻璃灯罩。
The lampshade has the advantages of good transmittance, no gas at high temperature, no yellowing, weatherability, high transmittance, convenient cleaning and beautiful, and can be used for coloring technology such as internal and external coating, grinding, vacuum coating, abrasive and aluminizing, electrostatic spraying and color spraying. It is suitable for interior decoration and lighting for lighting. At present, the high-end LED indoor lighting has adopted glass lampshade.
缺点：容易破碎
Shortcomings: easy to break
玻璃灯罩的工艺流程：
The process flow of glass lampshade:
1、取料
1. Reclaimer
拿起预热好的吹管，深入1300度的坩埚炉，不贪多，不嫌少。恰到好处的一团热玻璃，随热依附吹管上，墨镜、头巾、全副武装，准备转动你的吹管，一遍又一遍。
Pick up the preheated tube and go deep into the crucible furnace of 1300 degrees. A good group of hot glass, along with the heat attached to the blowpipe, sunglasses, headscarves, armed, ready to turn your blowpipe, again and again.
2、成型
2, molding
将取到的料放进模具中，运气、透过铁管将气吹入玻璃，撑出。
Put the material into the mold, and blow the gas into the glass through the iron pipe.
3、磨边
3. Edge grinding
高品质的玻璃的边缘用手摸上去是不会割伤手的，当然因为这个工艺的增加，产品的价格也不一样了，因为这道工艺的损耗很大。
The edge of high quality glass will not cut the hand by hand, of course, because of the increase of this process, the price of the product is different, because the loss of this process is very great.
4、退火
4. Annealing
玻璃不能任其自然降温，因为它的表面受空气冷却而收缩时，内部却因保有热度而膨胀，急速冷却会导致压力不平而开裂。
