1.Features of HLH-60
1)HLH-60 can be heated up to 850℃ in a band shape．
HLH-60 is the line-shaped heating unit using a rod-shaped halogen lamp.
Since parallel mirror width is 60 mm, parallel beam(focal length ∞), so it can be heated iin a band shape and heating time is short.
In the conventional parallel light parabolic mirror, the depth of the mirror became shallow, many light leaked to the surroundings, and it became the primary cause of obstacle.
Also, the proportion of the amount of beam that the parallel mirrors can control is low, and poor efficiency was also a drawback.
However, this HLH-60 has a beam recovery type deep reflective surface, which simultaneously realized reduction of leak beam and improvement of beam utilization rate.
Long-length heating is also possible, parallel mirror effective length can be made from 100 mm to 3000 mm.
In the case of plate heating, it is better to arrange many “HLH-35W/f∞”.
2)A perfect clean heating is realized, heating in a clean room or vacuum chamber is also possible.
The water-cooled type can be used by a vacuum chamber.
When it is placed in a vacuum chamber, there is gas emission which is slightly from inorganic glue in an early stage, so vacuum treatment is needed beforehand.

3.Focus and Line size of HLH-60
Since the parallel mirror is used, the width direction is almost uniform.
There is a gradient in the range of 70 mm from the left and right end faces, 140 mm in the center is uniformly heated.
Although the irradiation intensity is uniform as it is a rod-shaped lamp, since the heat escapes to the left and right peripheral parts, the temperature of the central part with less heat dissipation increases.
Reflector length of heating range + right end face 70 mm + left end face 70 mm is required.
(Example) When the heating range is 200 mm
Reflection mirror length of heating range 200 mm + right end surface 70 mm + left end surface 70 mm = 340 mm is required.
When emphasis is placed on the uniformity of the entire surface, a method of arranging a large number of HLH-35W/f∞ and heating the surface is suitable.
4.Temparature rising time of HLH-60
In infrared heating, the heating temperature changes depending on the infrared absorption rate of the object.
When it is irradiated for a long time, it becomes high temperature.
5.Voltage and lifetime of HLH-60
As shown in the above figure, if user lower it by 10% from the rated voltage, design life will be lengthens to 3 times.
If user lower it by 20% from the rated voltage, design life will be lengthens to 9 times.
