Lamp Heating Spot Heater
HSH-30 and HSH-35

High temperature heating by condensing the light of the halogen lamp Very low-cost heating implemented with lamp heating spot heater Condensed light diameter is approximately 0.196 in (5 mm) with a focal length of 0.59 in (15 mm). Heats up to approximately 2372℉ (1300℃) depending on the object to be heated.
Takes approximately 5 seconds when used in soldering.
Heats with light. Perfect clean heating is possible as a heating medium is not required, and can also heat in vacuum.

HSH-30 HSH-35 is provided with the front glass


Gold-plated mirror specification with highly efficient mirror design and high reflectance HSH-35 is provided with a front protection glass made of quartz
Separated into mirror and lamp units, and the mirror and lamp units can be replaced independently

Model naming method HSH-30/f◻(-øA)/◻v-◻w/+ options HSH-35/f◻(-øA)/◻v-◻w/+ options * Completely condensing when (-øA) is omitted. The condensed light diameter in this case will be almost as given in the top right table.

* Specify the irradiation range øA to heat a wide range with a certain degree of distribution. In this case, custom specification is required.

However, even with the condensed model, a wider range can be heated by moving from the focal point. For example, if f = 0.472 in (12 mm) of the above right table is used at an irradiation distance of 1.18 in (30 mm), an area covered by ø1.18 in (30 mm) can be heated.


The following is the characteristic diagram when the most powerful 12 V - 110 W halogen lamp is combined with HSH-30/f15 mirror.
In case of 110 W lamp, the voltage is above 7 V when continuous current is passed, and forced cooling is required.

* * Generally, higher the intensity of the light source, smaller the spot diameter even with the same mirror, and a high temperature is obtained.

* * 2 types general specification product and clean specification product are available for the lamp unit (lamp fixed to the aluminum base) (both same price). General specification product is safer for normal use. The usage of adhesive has been reduced to the minimum in the clean specification product, and Teflon electric wire has been used to support the use in clean rooms and in vacuum. However, the body temperature is higher than the general specification product, and precautions have to be taken as the disadvantage of this lamp is that it is prone to problems when the heat resistant limit is exceed.

Introduction to Various 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, irradiation diameter, and heating temperature

The photograph below is of HSH-30/f15/24v-75w (Model with focal length of 0.59 in (15 mm) irradiating at a distance more than the irradiation distance. (Supply voltage was 4 V and power consumption was approximately 5 W when the photo was captured so that the screen does not get scorched.

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, the diameter is between ø0.157 in (4 mm) to ø0.196 in (5 mm) mm in actual practice. 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 rradiation diameter This method is not accurate but practical. In addition, the light distribution is calculated using optical design software available at Fintech, and in some cases, the range with 80% of the power density at center is considered as the condensed light diameter. The result of both the methods gives almost the same value.

Temperature distribution measurement value, illuminance distribution measurement value 1 and value 2 at the focal plane for reference. This is raw data and may be difficult to understand. Information on the temperature distribution, the peak of the distribution is sagging because temperature is almost proportional to the cube root of illuminance (light energy density).

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.

To ensure reliable high temperature heating, a little ingenuity is required along with the selection of the heater. Adopt Cavity heating method


Irradiation at a distance of 0.39 in (10 mm) with a model of f = 15

Irradiation at a distance of 0.59 in (15 mm) with a model of f = 15

Irradiation at a distance of 0.78 in (20 mm) with a model of f = 15

Irradiation at a distance of 0.78 in (20 mm) with a model of f = 15 The shadow at the lower portion is the shadow of the filament support.

Information on the temperature rise of the main body

The temperature of the main body increases by approximately 200 K even for 24 V - 75 W type when continuous current is passed at 24 V. The main body temperature will rise up to 446℉ (230℃) if the room temperature is assumed to be 86℉ (30℃). This exceeds the heat-resistant limit of this product and can be dangerous. The increase in temperature will be naturally higher with the 85 W and 110 W types.

When continuous current is passed, ensure that the temperature of the main body is maintained at 302℉ (150℃) or less by using one the following methods, blowing in air with force, connecting to a heat sink or to objects that can radiate heat easily, using the water cooling unit WCU-30, or the piped air cooling spot heater which will be described later.

When continuous current is not passed, or when used by reducing the voltage, heat dissipation measures may not be required. However, periodically check the main body temperature when the lamp is being used.

Information on cooling of halogen spot heaters

Halogen spot heaters require forced cooling depending on the situation. In case of HSH-30/35, forced cooling is not required for continuous lighting up to 50 W. However, some sort of forced cooling is required for continuous lighting above 60 W.

Cooling method can be selected from the two types; water cooling and air cooling. In case of water cooling, just attach the water cooling unit WCU-30 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 that the flow is 0.014 gal/min (55 cc/min) or more in case of the 110 W lamp --> Refer Fig 1 below Air cooling will be as in Fig 2 below. The air cooling system cools by passing air in pipes. The required air quantity is 6.60 gal/min (25 L/min) for each 100 W. Ensure air flow of 7.13 gal/min (27 L/min) in case of the 110 W lamp.


Example of water cooling unit installation The required amount of cooling water is 0.013 gal/min (50 cc/min) for each 100 W of lamp power.





Air cooled halogen spot heater example The required air quantity is 6.60 gal/min (25 L/min) for each 100 W.
5.28 gal/min (20 L/min) for 75 W lamp. 5.81 gal/min (22 L/min) for 85 W lamp. 7.39 gal/min (28 L/min) for 110 W lamp
