1. Declaring:In order to confirm if these LEDs are suitable for your application, pretest is necessary before using it. This product presentation does not guarantee not contravene any patent. Relate to imports and exports LED product legal liability should be responsible by customer, so please verify relevant provision about the LED product in your target market. We may change specifications from time to time in the interest of product development, without prior notification or public announcement. An agreement of formal product specifications is required prior to mass production.
2、物料確認(rèn)：投料的LED、BIN等級(jí)是否吻合，如VF、CIE BIN、亮度等是否屬同一等級(jí)，同一等級(jí)的應(yīng)在一起使用。若不是同一等級(jí)的LED應(yīng)用在同一物件上，應(yīng)先評(píng)估其適用性，（若不同VF投在一起可能會(huì)發(fā)生亮度上的差異，不同CIE BIN<或不同波長(zhǎng)的LED>投在一起可能會(huì)發(fā)生色差）。
2. Before use:We suggest that the same parameters products should be used together, such as BIN coordinate, VF and luminous flux etc. Feasibility should be checked before applying to product (different VF or CIE BIN would lead to brightness and color discrepancy) to see if workable.
3、包裝儲(chǔ)存：
3.1、真空包裝的儲(chǔ)存：建議SMD系列LED存放在內(nèi)置干燥劑的干燥柜中，儲(chǔ)存環(huán)境為溫度5~ 30℃，濕度≤50%，儲(chǔ)存時(shí)間不超三個(gè)月。
3.2、拆開包裝后的儲(chǔ)存和使用：
a.拆包裝前應(yīng)檢查包裝確保無漏氣，以及干燥劑無變色（正常顏色為藍(lán)色，變成紅色、粉紅色代表受潮）。

3.2. Storage & using after opening packaging:
a. Please check whether air slipped into packaging and drier had changed color before opening packaging(Normal color is blue while red or pink means damp.
b. After opening the packaging under the environment of ≤30℃/60%RH , LEDs should be used out in 72hours(Level 4)
c. Regarding the balance LEDs under the condition of 30℃/60%RH workshop, we should repack it within 2hours.The storage condition as per item 3.1.
3.3 You have to dehumidify all LEDs at 70℃ for more than 24 hours if do not meet requirement of item 3.1 & item 3.2.
3.4 LED is surface mounting material, it will cause cracking of the lead frame or encapsulation glue during high temperature reflow soldering if damped. Then affect the light efficiency and lead to lumen decrease, color change.
3.5 The pad of chip and lead frame are composed of copper alloy with Ag-plated. And the surface silver layer can be damaged easily by corrosive gas. So You have to keep all LEDs away from corrosive substance and environment to avoid color fade or bad welding which may result in failure of LED. Especially you have to keep all LEDs away from high temperature and high humidity environment
4. 熱沉:
4.1. LED應(yīng)用終端產(chǎn)品應(yīng)重點(diǎn)考慮散熱設(shè)計(jì)，LED功率溫升系數(shù)由LED在線路板中的排布密度、熱阻、和環(huán)境溫度來決定。設(shè)計(jì)時(shí)LED產(chǎn)生的熱量不超過其最大極限值（參考LED Tj結(jié)溫），和其他電子元器件一樣，有必要考慮避開發(fā)熱元件的設(shè)計(jì)，LED正負(fù)極引腳Ts溫度絕對(duì)不可超過85°！

4. Heat Sink:
4.1. Thermal design of the end product is of paramount importance. Please consider the heat generation of the LED when making the system design. The coefficient of temperature increase per input electric power is affected by the thermal resistance of the circuit board and density of LED placement on the board, as well as other components. It is necessary to avoid intense heat generation and operate within the maximum ratings given in this specification.
4.2. The operating current should be decided after considering the ambient maximum temperature of LEDs.
