Abstract

The invention discloses an exposure lighting set and an exposure machine. The exposure lighting set comprises a tube-shaped light source, an inner water jacket, an outer water jacket and a tube-shaped light filter. The inner water jacket sleeves the tube-shaped light source. The outer water jacket sleeves the inner water jacket, thereby a space is formed between the inner and the outer water jackets. The tube-shaped light filter is disposed between the inner and the outer water jackets. The circumferential wall surface area of the tube-shaped light filter is larger than the product of the external diameter circumference and the external diameter length of the tube-shaped light filter. The invention has advantages of providing sufficient heat exchange area; facilitating the cooling system to quickly take away the heat of the tube-shaped light filter.

Description

technical field [0001] The present invention relates to an exposure machine, and in particular to an exposure lamp group. Background technique [0002] The existing ultraviolet exposure lamp group is generally composed of a lamp tube, an inner water jacket, an outer water jacket, and a circular tubular infrared cut-off filter (IR filter). When in use, the light emitted by the lamp will pass through the infrared cut filter, and the infrared cut filter will reflect or absorb the part of the infrared band in the light, so as to prevent the light in the infrared band from affecting the subsequent process, for example: causing unnecessary The temperature rises. [0003] Since the IR cut filter will reflect or absorb part of the infrared band of light, the temperature of the IR cut filter will increase significantly during use. Especially for high-power lamps, this temperature increase is even more pronounced. In order to avoid the high temperature from affecting the life of th...
