放射強度分布ならびに発散半角の測定方法
角度に応じた強度パターンを測定するため、LEDは発光強度が最大の軸に対して垂直な軸を中心に回転させます。 ゴニオ回転を得るためにはLEDを電動回転ステージのポストに取り付け、回転軸がLEDの発光面を通るようにしてください。 ステージは、KDC101などのDCサーボモータードライバによって制御し、LEDは半導体レーザードライバLD1255Rで駆動しています。 放射光はLEDから約300 mmの場所に設置したSiフォトディテクタDET36A2、またはゲルマニウム(Ge)フォトディテクタDET30B2で検出します。 LEDの中心が回転ステージCR1/M-Z7の中心上に配置されるようLEDマウントS05LEDMをレンズチューブSM05M10に埋め込んでいます。 迷光や散乱光がディテクタに当たらないよう、LEDよりもやや短いSM1レンズチューブをディテクタに取り付けています。 2つのアイリスSM1D12Cの開口部はLEDからディテクタの光路上に置かれています。 LEDに近いアイリスの開口径は10 mm、ディテクタに近いアイリスの開口径は3 mmです。
LEDが回転すると、光強度に比例するフォトダイオードディテクタの出力が各角度位置ごとにデータ収集カードによって記録されます。 LEDは+90°から-90°まで回転します。このとき0°は、強度が最大な軸がディテクタの軸に対して平行であるときとほぼ一致します。 出射光の発散半角はディテクタの最大出力の50%に相当する角度によって決まります。

Video Insight(How-to動画): LEDからの出力光をコリメートする方法
LEDやその他の寸法の大きなインコヒーレント光源からの光をコリメートするのは、意外にも難しい作業になる場合があります。エミッタのサイズ、コリメート用レンズの焦点距離と開口数(NA)など、それらのすべてがコリメートされたビームの特性に影響します。また、レンズが適切な位置にあることを見極めるのも難しい場合があります。この動画では、NAと焦点距離の異なる2つのレンズを使用して、いくつかのコリメート方法をデモンストレーションしています。そのほか、コリメートレンズによって生じるエミッタの像やその他の一般的なビームの特徴についてもご紹介します。
USB LEDの自作
こちらのページに掲載されている多くのLEDは、一時的な使用としてUSBポートから簡単に電源供給することができます。USBポートは、バッテリの充電やデータ転送などさまざまな用途に使用できます。一般的にはPCに付いていますが、それ以外の電子機器や壁面のコンセントにも多く見られるようになってきました。このタブではLEDへの電源供給を目的としたUSBポートの利用方法について順を追って説明しています。初めに、使用するLEDのスペックシートをよくお読みください。順方向電圧の典型値が5 V以上と記載されている場合、USBポートから電源供給することはできません(このことは下記で式2を用いて説明しています)。スペックシートは製品型番横の赤いアイコン()をクリックしてダウンロードいただけます。
使用例
当社のLED525Lを使用して、USBポートからの電源供給による連続照明装置を作成することができます。この装置には100 Ωの抵抗器を使用してください。この値の算出方法については下記の式3および4をご覧ください。

抵抗器の選択
USB>ポートは最大500 mA(状況によってはそれ以上も可能)の電流を提供できますが、ほとんどのLEDにとってこの電力は大きすぎます。そのため、LEDを直接USBケーブルに接続するとケーブルは数時間で焼損してしまいます。回路内でLEDの前に抵抗器を設置するとUSBポートからの電流を減少させてLEDを駆動させることができます。
用途に適した抵抗器を選択するために、まずはワイヤに電圧を与えるオームの法則から考えていきます。
V=IR (式1),
ここで、Vは電圧、Iは電流、Rは抵抗です。
この場合のVは電源からの出力電圧(Vs)とLEDの順方向電圧(Vf )の差となります(値については各LEDのスペックシートをご覧ください)。VfはLEDを点灯させるために必要な閾値とみなすことができます。この差を式1に置き換えると以下のようになります。
(Vs-Vf )=IR (式2).
Iは当社のLEDの駆動電流と一致します(値については各LEDのスペックシートをご覧ください)。Rを求める式を整理すると以下のようになります。
R=(Vs-Vf )/I (式3).
切り上げた値に最も近い抵抗器を選んでください。
LED525のスペックシートを見ると、最大DC順電流：30 mA、順方向電圧の典型値：3.0 Vaとなっています。最大電流よりも低い値でLEDを駆動し続けるため、20 mAの電流を設定します。USBポートには5 Vの電位があることがわかっているため、式3は次のようになります。
R=(Vs-Vf )/I = (5 V-3 V)/.02 A = 100 Ohm (式4).
100 Ωの抵抗は標準サイズであるため、切り上げる必要はありません。
複数のLEDへの電源供給
複数のLEDが必要な場合は、直列または並列に組み合わせることができます。直列に配置すると、LEDのVfが個数分倍増されるため、より大きなVs が必要となります。LEDにとっては並列に配置した方が有利です。この構成では、電源からより多くの電流が必要ですが、個々のVfはVs によって満たされます。ただし並列の構成では、安全のため各LEDが個別の抵抗器を付けておくことも非常に重要です。1つのLEDが故障した場合、残りのLEDは故障したLEDの電流も負担することになり、システム全体が焼損するおそれがあるからです。

(posted 2022-05-17 07:46:53.313) Hi! I have a hobby project—to measure/estimate human cone cell responses—in which I'd need to produce different combinations of visible light wavelengths (RGB only doesn't cut it) for observation with human eyes. Your LEDs in the visible light range (and light mixing rods etc) look potentially suitable, but since I'm new to optics, I thought I'd ask what you'd recommend for this use or if you'd even consider them safe for this kind of thing. The electronics side I believe I can handle.
Basically, I would want to control the (approximate) luminosity of the 10-or-so different wavelength LEDs, mix the light and present it to a human eye, either via an eyepiece or on some diffuse white surface, with the goal of finding different (known) spectra that produce the same perception. Obviously I'd be interested in rather small output powers. Also, do you think a light mixing rod is suitable for this? Or do you think one of your diffusers would be good enough? mdiekmann

(posted 2022-01-09 15:40:21.833) I am working on a team where we are developing a UV-based spectral sensor. We wish to make an addressable LED array to serve as a scanning UV source. The goal would be to make the array with LED devices that cover 250nm to 400nm with a wavelength separation of 10nm. Can Thorlabs work with us to produce such an array. This will be for a high volume medical application... initially we need to prototype the device... but eventually we would integrate this into a handheld measurement system, to be sold in quantities of 1000 to 100,000.
Please advise whether Thorlabs is able to provide such a device. Our company has experience in making commercial instrumentation... company name is Lightsense...based in Tucson, AZ.

3. Do you have the distribution figure before collimating for LED450L,the LED chip? So I can decide how the distribution is changing,or is it worth to sacrifice the LED power?
4. What's the best you can do to achive a much better collimated LED with such conpact package? Or should I say is it possible?
THANKS. nbayconich
(posted 2018-02-16 09:42:44.0) Thank you for contacting Thorlabs. The optical power is specified after the lens or window in these types of LED packages. We do not specify a collimating efficiency for use with an additional lens, the ability to collimate an LED will depend on the divergence and chip size of the LED however it is not possible to perfectly collimate an LED source in the same way a laser diode can be.
Please see our spec sheet located below for more information about the intensity distribution vs. angle below.
https://www.thorlabschina.cn/_sd.cfm?fileName=QTN015134-S01.pdf&partNumber=LED450L
If you use an AR coated lens to collimate this LED your loss in power should be reduced to a minimum. I recommend using one of the condenser aspheric lenses to collimate these LED's, and if the intensity distribution is not suitable for your application a diffused surface aspheric lens may be a better option.

I have some questions about LED2350P.
1)There is LED2350P Package TO-18(with Reflector) drawing on 3th page LED2350P datasheet. There is "window" on top LED2350P Package on the drawing. Word "window" is red color.
But we buy 2pieces of LED2350P without any window. Why there isn`t window on top our LED2350P? Now we place an order on 1 piece of LED2350P in firm Eurolase (in Russia). Can you make LED2350P with protective window for us? Is this window option?
2) You should correct and write warning in LED2350P datasheet: "LED2350P anod is connected to the LED2350P Package!"
3) We use LED2350P in such pulse mode regime: twidth=5uS, tperiod=0.5Sec, Ipulse=1A. LED2350P is mounted on heatsink. Can I use these pulse mode parameters for LED2350P? I can`t make twidth=1uS, as recommended in LED2350P datasheet.

(posted 2012-06-22 09:16:00.0) Response from Tim at Thorlabs: 5V will damage this diode. Please check the spec sheet for the forward voltage of this LED (~1.15V at 50mA). To use 5V you would need to include a resistor based on the desired current and forward voltage of the LED. With a forward voltage of 1.15V and 5V DC supply, you can see the series resistor needed to induce 50mA of current is just (5V-1.15V)/50mA. We recommend using a constant current source for these products. The bare LED has a half viewing angle of 15 degrees and the power is ~7.5mW. This is a divergent source and not very high power. However, care must always be taken when introducing optical elements into a beam path and any concerns of safety should be addressed with your laser safety officer. matt968

The LED341 is mid UV light emitting diode. It will emit light at approx 340nm (+/- 10nm) The window of the LED is a flat window and is not a lens. For your application the LED might proof best operation to involve a laser diode driver. You will have precise control over the light being emitted (power).
Im not sure how you want to use the emitting light. The light will diverge at about 15 degrees from the emitter. Typically such light would need to captured by collimation and focusing. But the type of optics required would depend on you use. abytas

LEDMT1Eの電気回路図
- T-1 3/4パッケージLED用USB電源供給マウント
- 51 Ωまたは62 Ωの電流制御抵抗内蔵
- SM05外ネジ
- LED電源モジュール用Micro-B - Type-A変換USBケーブルが付属
こちらのUSB電源駆動LEDマウントは、T-1 3/4パッケージのマウント無しLED用で電源供給とLED取付けソケットの両方が付いたコンパクトな筐体です。様々な電流要件に対応するため、51 Ωまたは62 Ωの電流制御抵抗付きのLEDマウントをご用意しております。モジュールは筐体背面のmicro-B USBポートからUSB電源、または付属のUSB-Micro-B USBケーブルにつないでPCより電源が供給されます。筐体にはSM05外ネジが付いており、ケージシステムやSM05ネジ付き部品が取り付けられます。
LEDを取り付ける際には、筐体に刻印されている長さを参考にリード線を切断してください(右の図をご覧ください)。LEDは、(+)にアノード、(-)にカソードを挿してください。LEDを取り付ける際に過度の力を加えると電極リード線が曲がる恐れがあります。
こちらの電源供給マウントは抵抗値と入力電圧が固定です。LEDに適したマウントを選ぶことでLEDへのダメージが最小限に抑えられます。一般的に抵抗値の低いマウントは順電流を増加させ、それに比例してLEDの光出力が増加します。しかし順電流がLEDの最大電流を超えると、LEDの恒久的なダメージの原因になる場合があります。LED使用時に推奨される最小抵抗値(R)は、下記の式を用いて求められます。
マウントの入力電圧(VI,Source)は5V、そして典型的な順電圧(VF,Typ) ならびに最大順電流(IF,Max)は、各LEDによります。これらの値についてはLEDの仕様をご覧ください。

LEDマウントLEDMFは、付属のアダプターリング(TO-18用はØ4.7 mmアダプタ、T-1 3/4用はØ5 mmアダプタ)の1つを使ってT-1 3/4やTO-18パッケージを保持する設計となっております。また、TO-18Rパッケージは直接保持することが可能です。LEDはマウント上部にあるキャップスクリュを2 mm六角レンチで締め付けることによって固定されます。L字型のマウントにはM4キャップスクリュが使用できるザグリ穴(貫通穴)があるので LEDMFをØ12 mmまたはØ12.7 mmポストに取り付けることができます。
LEDマウントS05LEDMにはSM05ネジ加工、S1LEDMにはSM1ネジ加工が施されています。 こちらは、付属のアダプターリングを用いて当社のTO-18、TO-39、TO-46、T-1 3/4パッケージを保持する設計となっております。外ネジ加工なので様々なSM05またはSM1ネジ対応オプトメカニクス部品に適用できます。
固定リングをマウントにねじ込む、またはマウントを他の部品に結合する際には当社のスパナレンチのご使用をお勧めいたします。 調整機能付きスパナレンチSPW801は、LEDの固定リングをマウントにねじ込む際やマウントを他の部品に結合する際に使用できます。 また右の表には各マウントに対応可能なスパナレンチが記載されています。
