It is linear side by side to spend direction, the linear light source being made of the linear a plurality of light-emitting elements 10 side by side is set as ultraviolet lighting and is shot to death
The light source of bacterium device 1.
In addition, container 11 preferably at one end have opening portion, the closed construction of lid which can be opened and closed.
Using the lid that can be opened and closed, thus for example, when the coolant liquid 12 in container 11 is reduced because of volatilization, can be supplemented from opening portion
Coolant liquid.
In addition, lid used in container 11 is preferably locally having for gas to pass through and is hardly passing through coolant liquid
The components such as multiple aperture plasma membrane.In this case, for example, the gases such as coolant liquid 12, air in container 11 are because of light-emitting component 10
Fever and when producing expansion, external dissipation of the gas that pressure can be made to increase to container 11.
In the example depicted in figure 1, the seal cap 14 that can be dismounted relative to the opening portion of container 11 is used as lid,
Seal cap 14 is through with the power supply line 15 for supplying power supply to light-emitting component 10 via circuit board 13.

It is penetrated for the light issued from light-emitting component 10, there is the pyroconductivity of the pyroconductivity (0.0241W/ (mK)) higher than air.
As the coolant liquid 12 having the quality that, such as it is able to use fluorine class torpescence liquid, silicone oil.
Silicone oil, perfluoropolyether fluorine class torpescence liquid (for example, Galden (registered trademark) of Solvay corporation) supply
UV-A, UV-B UV light permeability.In addition, the fluorine class torpescence liquid with fluorine carbon (PFC) construction is (for example, 3M corporation
Fluorinert (registered trademark)) also for UV-C UV light permeability.Therefore, the light-emitting component for generating UV-C ultraviolet light is being used
In the case that 10 are used as light source, it is able to use the fluorine class torpescence liquid with fluorine carbon construction, the material as coolant liquid 12.
Coolant liquid 12 is directly contacted with light-emitting component 10, and the heat of light-emitting component 10 can be made efficiently to dissipate to coolant liquid 12
Ease.On the other hand, coolant liquid 12 has electrical insulating property, therefore there is no the worries that short circuit is generated in light-emitting component 10.In addition, cold

Every function, therefore can prevent light-emitting component 10, circuit board 13 from corroding equivalent damage as caused by outside air.
When ultraviolet light sterilizing unit 1 acts, the temperature of the coolant liquid 12 of the surrounding of light-emitting component 10 rises and court
Direction is mobile on vertical, and the convection current of coolant liquid 12 is thus caused in container 11.Coolant liquid 12 is automatically followed in container 11
Ring, thus heat dissipation effect is bigger.
Prepare the LED patch for installing 5 generation UV-A as light-emitting component 10 on circuit board 13, and is soaked in
The ultraviolet light sterilizing unit 1 of Fluorinert as coolant liquid 12, if confirmed to send out LED patch by the present inventor
Light, then the temperature on the surface of LED patch rises to 56 DEG C and is saturated.In addition, the temperature of Fluorinert rises to 40 from 22 DEG C
DEG C and be saturated.On the other hand, if sending out LED patch without using Fluorinert (in the state that LED patch is covered by air)
Light, then the temperature on the surface of LED patch rises to 124 DEG C.This is indicate ultraviolet light sterilizing unit 1 real by coolant liquid 12
One example of the cooling effect of existing light-emitting component 10.
In order to more improve the cooling effect of light-emitting component 10, coolant liquid 12 also may include dispersing agent, the dispersing agent
Pyroconductivity is higher than coolant liquid 12, has electrical insulating property, relative to 10 torpescence of light-emitting component.As such dispersing agent, energy
Enough using glass microballoon, nano silica etc..Dispersing agent is preferably penetrated for the light issued from light-emitting component 10.In addition, having
The dispersing agent of the diameter shorter than the wavelength of the light of light-emitting component generation, due to not reflecting the light of the generation of light-emitting component 10, so excellent
Choosing.
In addition, thus the amount of the coolant liquid 12 in solution 11 is reduced, therefore can be reduced by container 11 using dispersing agent
The displacement of coolant liquid 12 caused by pressure change when installing the lid of seal cap 14 etc. additional.
In addition, coolant liquid 12 also may include fluorophor, quantum dot.The light issued from light-emitting component 10 is ultraviolet light, because
This directly can not visually confirm that ultraviolet light sterilizing unit 1 is that (light-emitting component 10 is luminance to action state such case
Such case), but the situation can visually be confirmed by fluorophor, shining for quantum dot.
