Notes
  1. The import of electronic parts requires relevant certificates, such as: IC, capacitors, transistors, power supplies... and other electronic related parts (such as motherboards, power transformers), and we cannot assist you in importing.
  2. The seller does not provide return compensation and other responsibilities
  3. Batteries are considered dangerous goods under international shipping regulations and cannot be shipped.
  4. Please note: Sellers with a rating lower than 50 or an overall rating lower than 98% cannot provide compensation for non-arrival of goods. Please choose a reputable seller.
電流容量の大きな定電流ダイオードは見当たりません。

しかし、これはLi-ionバッテリー(3.7V)に特化した製品で、定電流値の可変設定およびPWM調光が可能なモジュールと高出力5W COB・LEDセットとなります。
 
【可変定電流モジュール・製品仕様】
IC: CN5711搭載
動作電圧範囲: 2.8V6V(Li-ion:3.7Vが標準設定)
オンチップパワーMOSFET
低ドロップアウト電圧: 0.37V @ 1.5A
LED電流: 最大1.5A
出力電流精度: ± 5%
チップ温度制御
LED電流保護
【可変定電流モジュール・動作仕様】
□ CEピン(チップイネーブル入力)
  High:動作モード(通常では、電源+に接続)
  Low:停止モード
  発振周波数2kHz以下でPWMによる調光が可能
□ LED電流設定
  ILED = 1800RISET (単位:A)
  (EX.) RISET=1.2KΩであればILED=1.5Aとなる
  本品はすでに1KΩが実装されており、ADJVRとシリーズとなります。
5W COBLED動作仕様】
LEDチップ: 30パラレル
動作例①: VF 3.2V IF 1.0A
動作例②: VF 3.3V IF 1.5A
5W COBLED考察】
動作例①と動作例②の明るさ比較は、大きな差異は見受けられませんでした。
また、発熱面を配慮すると動作例①をお薦めします。
LEDの特性上飽和領域では、僅かなVFの変化でIFが大きく変動します。
動作電流1A以上の場合は、電圧降下を配慮し20AWG以上の線材が理想です。
発光面積が大きく、単位面積当たりの発光電力が低くなり放熱設計が楽になる。
   (動作電流を1A以下にすると、ヒートシンクがほぼ不要となる。)
シビアな電流設定の場合は、ADJVR多回転ポテンションメーターへの換装をお薦めします。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.

※ Note: Photos provided to sellers should not contain any foreign-related information.
