Problems solved by technology

[0015] However, recently, it is not uncommon to see large panels with a size exceeding 2000mm as a liquid crystal panel as a workpiece, and the length of the discharge lamp used to process the panel is of course required to be longer
Therefore, even if the above-mentioned device with a cooling structure is adopted, the handling of the long discharge lamp will become extremely complicated, and it will be extremely difficult to allow the discharge lamp to enter and exit the cooling jacket.

Embodiment Construction

[0065] In the ultraviolet irradiation device 10, the housing 11 has a pair of outer walls 12a and 12b, and the opening and closing part 13 is formed on only one of the outer walls 12a depending on the working environment in many cases.

[0066] Inside the housing 11, a cooling pipe 14 made of a translucent member such as quartz glass is provided. Although only one cooling pipe 14 is shown in the figure, it is generally provided with a plurality of cooling pipes 14 .

[0067] The cooling pipe 14 is supported by inner walls 16a, 16b suspended from the top 15 of the housing 11 . Further, cooling air passages 17 a and 17 b are formed between the inner wall 16 and the outer wall 12 .

[0068] The discharge lamp 20 having a base is supported by being inserted into the cooling pipe 14, and is cooled by air flowing through the cooling air flow path 17a→cooling pipe 14→cooling air flow path 17b.

[0069] figure 2 A discharge lamp 20 having a base according to the present invention is...

Abstract

The invention discloses a discharge lamp with a pedestal and an ultraviolet ray irradiation apparatus and in particular to a luminous tube which is internally provided with dielectric of gas for discharging. A pair of electrodes are oppositely disposed outside the luminous tube. The discharge lamp with a pedestal of an electricity supply mechanism for the electrodes is arranged at one end of the luminous tube. The invention aims to provide an inner construction which allows an easy and smooth insertion of a long-shaped discharge lamp into a cooling pipe of an ultraviolet ray irradiation apparatus. The pedestal is mounted at a non-electricity supply side end of the luminous tube which is opposite to the side end of the electricity supply mechanism, and is provided with a guiding mechanism which slides and guides along the luminous tube.

Description

technical field [0001] The present invention relates to a discharge lamp with a base and an ultraviolet irradiation device using the discharge lamp with a base, especially for the manufacture of liquid crystal substrates such as televisions and monitors, especially for the use of liquid crystal materials containing photosensitive materials Discharge lamps and ultraviolet irradiation devices with bases for liquid crystal manufacturing. Background technique [0002] In a liquid crystal display device, by utilizing the refractive index anisotropy of the liquid crystal, a voltage is applied to the liquid crystal to change the orientation of the axis of the refractive index anisotropy, thereby controlling the brightness of light transmitted through the liquid crystal panel. In such a liquid crystal display device, it is very important to control the alignment of liquid crystal molecules in a state where no voltage is applied to the liquid crystal. [0003] Recently, in the produ...
