- the spacer 103 is a member that supports the substrate 102 and is in mechanical contact with the housing 104 and the lid 105 as well. By adjusting the position of the spacer 103 , the optical axis of the light emitted by the LED 101 can be aligned with the opening of the optical path 113 and the optical axis of the optical component 112 . That is, the spacer 103 supports the substrate 102 and also serves as a member for aligning the optical axis.
- Light emitted by the LED 101 is combined by a combining device 111 and emitted toward an optical path 113 via an optical component 112 (for example, a lens or a slit). This light is output from an opening of an optical path 113 via an optical component 112 (for example, a lens, a slit, etc.).

- the constant temperature liquid may be, for example, a constant temperature liquid used in a constant temperature bath provided for maintaining the temperature of the sample in the automatic analyzer.

- ⁇ Embodiment 1 About the principle of the device> When the LED light source device 1 is powered on, the LED 101 emits light, and the temperature of the LED 101 (and its surrounding members) gradually rises over time. The amount of temperature rise (temperature rise rate) with respect to the elapsed time gradually decreases, and when the temperature reaches a certain level, the temperature stabilizes.
- the light intensity and wavelength of the light emitted by the LED 101 have temperature characteristics, and these fluctuate according to the temperature.
- the characteristics of emitted light must be stable. Therefore, it can be said that it is desirable to quickly stabilize the characteristics of the emitted light after the LED light source device 1 is powered on.
- the heat capacity of the substrate 102 and the heat capacity of the spacer 103 are reduced by minimizing the volume of the substrate 102 and the volume of the spacer 103 as much as possible.
- the substrate 102 and the spacer 103 are made of a material such as metal with high thermal conductivity (for example, aluminum).
- the heat from the LED 101 is efficiently propagated to the surrounding members such as the housing 104, so that the temperature of the LED 101 can be quickly increased to a stable state. Thereby, the light intensity and wavelength of the LED 101 can be quickly stabilized.
- the thermal conductivity of the substrate 102 and the thermal conductivity of the spacer 103 be higher than the thermal conductivity of the housing 104 and the thermal conductivity of the lid 105 .
- the thermal conductivity of the housing 104 and the thermal conductivity of the lid 105 can be, for example, 10 W/(m ⁇ k) or more and 50 W/(m ⁇ k) or less.
- the heat capacity of the housing 104 and the heat capacity of the lid 105 are increased by increasing the volume of the housing 104 and the volume of the lid 105 as much as possible.
- the housing 104 and the lid 105 are less susceptible to temperature fluctuation due to disturbance, so that temperature fluctuation after the operation of the LED 101 is stabilized can be suppressed.
- the temperature fluctuation due to disturbance can be suppressed to some extent by the thermal conductivity of the housing 104 and lid 105 respectively. That is, if the thermal conductivity of these members is small, even if the outside air temperature fluctuates, the propagation of the fluctuation to the inside of the device can be suppressed to some extent.
- the water channel for circulating the constant temperature liquid has a role as a temperature adjustment mechanism for adjusting the temperature of the LED light source device 1 .
- the temperature of the constant temperature liquid is set to a temperature higher than the ambient temperature of the LED light source device 1, for example. In this case, if you want to lower the temperature, you can reduce the amount of water and the amount of heat that propagates will decrease, so the temperature will naturally drop. There are advantages that are possible.
- the temperature control mechanism can also be configured by using an element capable of both heating and cooling to heat and cool the housing 104 and the lid 105 instead of or in combination with the water channel.
- an element capable of both heating and cooling to heat and cool the housing 104 and the lid 105 instead of or in combination with the water channel.
- a heater with a thermostat, a Peltier element, or the like.
- the constant temperature liquid may be shared with the constant temperature liquid circulation mechanism provided in the automatic analyzer to which the LED light source device 1 supplies light.
- An automated analyzer may have a constant temperature bath for maintaining a constant temperature of the sample, and a constant temperature liquid is circulated around the constant temperature bath to maintain the temperature of the constant temperature bath. In this case, by supplying the constant temperature liquid to the LED light source device 1, the LED light source device 1 does not need to have its own constant temperature liquid supply source, which is useful.
- the control of the constant temperature liquid flow rate, etc. may be entrusted to the automatic analyzer.
- the LED light source device 1 itself may have the flow rate control function by arranging a flow rate adjustment valve or the like inside the LED light source device 1 .
- a device such as a controller that gives control instructions may be incorporated inside the LED light source device 1 or may be configured as a device outside the LED light source device 1 .
- the optical path 113 has an opening through which the light emitted by the LED 101 passes. This opening allows air to flow in and out between the internal space of the LED light source device 1 and the outside air. Since such inflow and outflow of air causes temperature fluctuations in the internal space of the LED light source device 1, it is desirable to suppress such ingress and egress as much as possible. That is, it can be said that it is desirable to keep the aperture size of the optical path 113 to the minimum required for light emission.
- the cover 105 may be partially provided with a hole through which wiring for supplying power to the LED 101 is passed.
- the aperture size of the hole is smaller than the aperture size of the optical path 113 . That is, it is desirable that the ventilation capacity of the internal space of the LED light source device 1 is maximized by the opening size of the optical path 113 . As a result, heat exchange between the internal space and the outside air is minimized, so temperature fluctuations of the LED 101 can be suppressed.
- a ventilation hole is provided in addition to the opening of the optical path 113, it is desirable to seal the hole with a suitable sealing material or the like.
- the volume of the spacer 103 is affected by the size of other members, but in order to reduce the heat capacity of the spacer 103 as much as possible, the volume of the spacer 103 should be at least smaller than both the volume of the housing 104 and the volume of the lid 105. It is desirable to The same applies to the volume of substrate 102 .

- the heat generated from the LED 101 is quickly propagated, so that the light amount and wavelength when the LED 101 is powered on can be quickly stabilized.

As a result, it is possible to quickly stabilize the light amount and wavelength when the LED 101 is powered on.
- the housing 104 and the volume of the lid 105 are made as large as possible (for example, making them smaller than both the volume of the substrate 102 and the volume of the spacer 103), the housing 104 and the heat capacity of the lid 105 are increased. Thereby, it is possible to suppress the temperature fluctuation after the operation of the LED 101 is stabilized.

On the other hand, when the LED light source device 1 is used in a device such as an automatic analyzer that turns light on and off frequently, the effect of the configuration of the first embodiment is significantly exhibited.
- Embodiment 1 if the amount of heat generated from the LED 101 is relatively small, the temperature adjustment mechanism can be omitted.
- the housing 104 and the lid 105 already provided with a temperature control mechanism in a light source device using a light source that generates a relatively large amount of heat can also be used for the present invention. In this case, there is an advantage that most of the members other than the light source itself, such as the substrate 102 and the LED 101, can be diverted.

Abstract
Description
図1は、本発明の実施形態1に係るLED光源装置1の構造を説明する断面図である。LED光源装置1は、試料に含まれる物質の吸光度を測定することによりその物質を定量化する分析装置において、光源として用いられる。例えば血液試料に含まれる測定対象物質を、光照射によって測定する自動分析装置において、光源としてLED光源装置1を用いることができる。
LED光源装置1に対して電源が投入されると、LED101が発光するとともに、LED101(およびその周辺部材)の温度が時間経過にともなって次第に上昇する。経過時間に対する温度上昇量(温度上昇率)は次第に小さくなり、ある程度の温度に達すると温度は安定する。
恒温液を循環させる水路は、LED光源装置1の温度を調整する温度調整機構としての役割を有する。恒温液の温度は、例えばLED光源装置1の外気温度よりも高い温度に設定する。この場合は、温度を下げたければ水量を減らすことによって伝搬する熱量が低下して自然に温度が低下するので、冷却動作が可能な素子などを別途設ける必要がなく、簡便な構成によって温度調整が可能となる利点がある。
本実施形態1に係るLED光源装置1において、基板102の熱伝導率とスペーサ103の熱伝導率は、筐体104の熱伝導率と蓋105の熱伝導率いずれよりも高い。これにより、LED101からの発熱が速やかに伝搬するので、特にLED101に対して電源が投入されたときの光量や波長を、速やかに安定させることができる。
実施形態1において、LED101の動作が安定したか否かを判定するためには、例えばLED101が出射する光量の直近10分間における平均に対する分散が2%以内に収まっているか否かなどのような基準を用いることができる。同様の基準は、筐体104や蓋105などの部材の温度が安定しているか否かを判定するために用いることもできる。LED光源装置1の各部材の材料や体積などを設計する際には、このような基準の下で本発明の目的を達成することができるようにすればよい。
本発明は上記した実施形態に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施形態は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施形態の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施形態の構成に他の実施例の構成を加えることも可能である。また、各実施形態の構成の一部について、他の構成の追加・削除・置換をすることが可能である。
