We are one of the biggest Importer of UV Curing & Metal Halide Lamps. We got a variety of UV Lamps from 4” to 70” in power range of 200w/inch to 500w/inch.
Standard UV Curing Lamps : These lamps, also called mercury arc lamps, are the workhorse of the light curing industry. They combine cure efficiency with design versatility and moderate cost. An electrode type medium pressure lamp consists of three major components:
- A quartz glass sleeve
- Fill material, typically argon and precisely dosed amount of liquid mercury
- Electrodes sealed into the end of the quartz sleeve.
A high voltage is applied to the lamp across the electrode terminals. The voltage field ionizes the argon and produces heat to vaporize the mercury, which creates a pressure of about two atmospheres. This pressure is needed to maintain a balance between the required high intensity while maintaining the spectral output essentially in the UV region. The mercury vapor arc, which is created, exhibits the unique property of high emission of light in the ultraviolet region of the spectrum. In particular, intense emission occurs in the 240-270 nm and 350-380 nm areas, which is where typical UV photoinitiators absorb. This intense light beyond the violet region of the visible spectrum has sufficient energy to interact with photoinitiators and cause their fragmentation, which initiates polymerization. Some visible light and infrared radiation are also generated.
We import electrode type mercury vapor lamps in sizes ranging from a couple of inches to 135 inches in length and various power levels ranging from 100 Watts/inch to about 800 Watts/inch. The most popular lamps are in the 200-400 Watt/inch range. |
