Lamp Heating Spot Heater HSH-60Heater that heats by condensing the light of the halogen lamp with a concave mirrorThe light output rises almost instantaneously, simple and accurate output control is possible with voltage controller. A medium is not required for heating as the heating is done with light, completely clean heating is possible at low cost. In addition, heating is possible in vacuum. Condensed light diameter: approximately ø0.236 in (6 mm) (combination of short-focus mirror and 150 W lamp) Heating temperature: Maximum approximately 2552 ºF (1400 ºC) (in case of short focal length mirror) This heater in the case of 150 W lamp can be lit continuously when used in the normal open atmosphere, but when used in a closed atmosphere or if a lamp of more than 150 W is used, then a water cooling unit (WCU-60) or air cooling or fan cooling units described below will have to be used.

The latest products do not have the fins shown in the photographs. Price PDF file for printing Option symbol /+WCU: water cooling unit /+VAC: Vacuum supported /+QFG: Quartz front glass Heat radiating fins had been provided for a part of the mirror in HSH-60, and will be discontinued once the stock is used up. → Even if heat radiating fins are not provided, the rise in temperature will be in the safe zone for the 150 W lamp. Also, the effect of the fin cannot be confirmed if forced air cooling is not provided, but the application of the forced air cooling is practically difficult. Since water cooling unit (WCU-60) has been kept ready as an option in case of overheating, heat radiating fins have been removed. The lamp base of the spot heaters above HSH-60 (see the figure below. Aluminum component that has been fixed after the lamp has been pre-focused) has been filled with magnesia powder. This is mainly expected to have a heat dissipation effect. The temperature of the lamp sealing portion will reduce by approximately 68ºF (20ºC) due to the filling of magnesia powder. → Temperature data Representative example of features HSH-60/f30/36v-450w |

Introduction to Various Types of Power Supply Units |
|
| The halogen lamp has a large inrush current and may not work with the normal power supply. The following is an introduction to supported types of power supply. The following general power supply can support normal usage. When high reliability and functionality is required in cases such as industrial applications, dedicated power supply must be used. | |

Irradiation distance and irradiation diameter The photograph below is of HSH-60/f30/24v-150w (Model with focal length of 1.18 in (30 mm) irradiating at a distance more than the irradiation distance. The condensed light is naturally the smallest when irradiation distance = focal length. The diameter when the condensed light is the smallest is mentioned as approximately ø0.196 in (5 mm) in the drawing, when models with f = 15 mm and f = 30 mm are compared, f = 30 mm is 20% higher and is approximately ø0.236 in (6 mm). The condensed light diameter will change depending on the lamp, the smaller the electric power, smaller will be the condensed light diameter. (Almost proportional to the square root of the power) → Reference“Physics of lamp heating” What does “Condensed light diameter” refer to in the field of lighting, the range in which the illumination is half the central illumination is called the irradiation range in general. However, in the field of lamp heating “Area in which the power density is half of the power density at the center” does not make much sense. Therefore, Fintech refers to “Condensed light diameter” as the “Area in which heating is possible to almost the same level as the center”. Measuring the diameter optically is a little difficult, and as a practical method of measurement, a burn mark is created on paper and the range burnt to nearly the same extent as the center is considered as “Irradiation diameter”. This method is not accurate but practical. This is the measurement data of the temperature distribution in the focal part measured using a thermocouple for reference. This is raw data and may be difficult to understand. Since temperature is proportional to the cube root of illuminance (light energy density), the sagging of the distribution peak has spread out. As can be seen in the photo below, the condensed light diameter is large even when the irradiation distance is closer or further than the focal length. A wider range can be irradiated using this property. However, an uniform irradiation cannot be obtained. When high accuracy light distribution is required, a mirror with special ability to control the light distribution is required instead of the simple elliptical mirror. However, getting a completely flat light distribution is very difficult due to factors such as non-uniformity of the filament and the focusing accuracy. → Reference“Optics of lamp heating”. |

 Irradiation at a distance of 0.59 in (15 mm) with a model of f = 15 |
The convergence of the model with focal length 0.59 in (15 mm) is better compared to the model with focal length 1.18 in (30 mm), and a smaller spot is obtained as shown in the photograph on the left side. Focal length 2.36 in (60 mm) and 4.13 in (105 mm) have also been prepared as standard products, but as shown in the following table, more the focal length larger will be the condensed diameter. Therefore, irradiation power density will weaken almost inversely proportional to the square of the irradiation diameter.

Connected with water cooling unit WCU-60 Almost not required with the 150 W lamp, but when used in harsh conditions cooling will be required. In addition, cooling is mandatory when class of 300 W or more is used. Air-cooled type is also available (described later) Information on cooling of halogen spot heaters Halogen spot heaters require forced cooling depending on the situation. In case of HSH-60, forced cooling is not required for continuous lighting up to 150 W However, some sort of forced cooling is required for continuous lighting with 300 W or 450 W. Cooling method can be selected from the 3 types of water cooling, air cooling and fan cooling. In case of water cooling, just attach the water cooling unit WCU-60 to the normal specification product. The required amount of cooling water is 0.013 gal/min (50 cc/min) for each 100 W of lamp power. Ensure a flow rate of approximately 0.039 gal/min (150 cc/min) in case of the 300 W lamp. Air cooling and fan cooling systems are as shown in the figure below. The air cooling system cools by passing air in pipes. The required air quantity is 3.96 gal/min (15 L/min) for each 100 W. Ensure an air flow of 11.88 gal/min (45 L/min) in case of the 110 W lamp. However, during high temperature heating when the distance from the work piece is less, increase the quantity of cooling air as heat will be reflected from the work piece. Criteria is that the body temperature must be 302ºF (150 ºC) or less. A DC fan is provided for fan cooling system in case of HSH-60. Use the fan by applying the prescribed voltage. Ensure proper polarity as it is a DC fan.  Air cooled halogen spot heater Cools by passing air in pipes. Required air quantity is 6.6 gal/min (25 L/min) for each 100 W  Fan cooled halogen spot heater Air cooling with the supplied fan. Cannot be used in vacuum and high-temperature atmosphere. |
