　　購買防雨電源最關(guān)注什么?

　　The problem that customers care about most

　　在前期產(chǎn)品立項中，萊福德針對購買景觀亮化電源客戶最關(guān)心的問題進行了調(diào)研，發(fā)現(xiàn)大家雖表述各有不同但最終都落腳在了可靠性上�；仡^想想，也不難理解——景觀亮化電源常用于戶外的各項公共工程，如出現(xiàn)故障，需要現(xiàn)場搭梯子、腳手架、甚至封鎖路才能維修，不僅維護成本非常高昂，且將直接嚴重影響企業(yè)的名聲。

　　Rain-proof LED driver is often used for landscape lighting. In the new product preparation stage, a survey on the problem that customers do care about most when buying LED drivers used for landscape lighting was conducted by Lifud. And it is found out that the lifetime or reliability of the LED driver, which is closely linked with a company’s reputation is the most concerned problem.

　　哪些使用因素會影響防雨電源壽命及可靠性?

　　The factors that affect the lifetime and reliability of LED driver used for landscape lighting

　　①發(fā)熱散熱：電子產(chǎn)品的壽命在很大程度上取決于工作溫度，溫度越高壽命就越短，此時電源本身的發(fā)熱與散熱就極為重要了。而其中減少發(fā)熱為治本，加強散熱為治標，雙管齊下則為優(yōu)。

　　Heating and cooling: The lifetime of electronic products largely depends on its operating temperature. That is to say, the higher the temperature, the shorter the lifetime. Thus, it is necessary for us to reduce heat and at the same time strengthen heat dissipation in order to extend the lifetime of LED drivers. ②雨水潮氣：水就不用解釋了，易造成產(chǎn)品短路，電源直接失效;而潮氣同樣，當濕度達到一定程度(90%以上)，電源在該環(huán)境同樣容易造成短路失效。

　　Rain and moisture: It is well-known that water may cause drivers short circuit and even to be damaged. Likewise, when the humidity reaches more than 90%, the LED driver is also easy to be damaged due to short circuit. ③灰塵雜物：灰塵雜物的影響，除了由于擁有酸性、腐蝕性的霉菌和附著物會對電子器件表面造成損傷，還跟后面會講到的加強散熱常用的風扇有關(guān)-可能被固體雜物卡死造成電源失效。

　　Dust and debris: The acid and corrosive fungi or attachments carried by dust and debris not only can cause the surface of electronic devices to be broken, but the driver of the fan used for cooling to be damaged due to short circuit.

　　應(yīng)對以上影響常見防雨電源有哪幾類設(shè)計?

　　The common types of design on the LED driver used for landscape lighting to cope with the above problems

　　景觀亮化電源結(jié)構(gòu)上主要有兩種設(shè)計因素：灌膠、風扇。

　　There are two main design factors in the structure of the LED driver used for landscape lighting: gluing and Fan.

　　風扇冷卻

　　作用：通過強制通風給關(guān)鍵發(fā)熱器件加強散熱。

　　副作用：

　　①風機的使用會降低電源整體效率，提高產(chǎn)品發(fā)熱，且增加噪音。

　�、诠收下试龈�，運輸、跌落、灰塵雜質(zhì)、潮水……等都對風扇產(chǎn)生損害影響，一旦風扇故障，電源很快就會失效。

　　Fan cooling

　　Cooling: The heat dissipation (cooling) of key heating devices is enhanced by forced ventilation.Side effects:①The overall efficiency of the LED driver will be reduced by fan cooling. And also the use of fan will increase heating and noise.② The fan used for cooling is easy to be damaged by transportation, falling, dust and debris, tide and etc, which means the LED driver will be damaged subsequently.

　　自然冷卻(無風扇)

　　散熱：通過外殼自然散熱。副作用：由于沒有風機強制散熱，就要求產(chǎn)品本身發(fā)熱低、導熱好，對技術(shù)及工藝有更高的要求。如電路設(shè)計：效率越高，發(fā)熱越低。

　　Natural coolingCooling: It can be achieved naturally through the case of the LED driver.Side effects: The driver is required to have low heat, good heat conduction, better technology and process, such as circuit design: the higher the efficiency, the lower the heat.

　　半灌膠

　　作用：

　�、俜乐咕植繙囟冗^高。對元器件所產(chǎn)生的熱量進行傳導、散發(fā)，加強產(chǎn)品導熱散熱。

　�、谔岣叻莱毙阅�。部分元器件已被導熱膠覆蓋，能夠充分防潮。

　�、厶岣叻�(wěn)定性.導熱(絕緣)膠覆蓋了PCB及部分元器件，絕緣性能穩(wěn)定，且更加穩(wěn)固、牢靠，能夠充分抵抗沖擊、振動。

　　副作用：成本提高

　　Semi-gluingFunction: ①Prevent local temperature from being too high.This type of design is aimed to strengthen the thermal conductivity and heat dissipation of products by conducting and sending out the heat generated by components.②Improve humidity resistance.Part of components have been covered with thermal conductive adhesive, which can achieve humidity resistance.③Improve stability.Thermal conductive (insulation) adhesive covers PCB and part of components, which can fully resist impact and vibration owing to its stable insulation performance.Side effects: Higher cost 根據(jù)以上因素，景觀亮化電源結(jié)構(gòu)主要有以下兩種設(shè)計：①風扇冷卻常規(guī)防雨電源;②自然冷卻半灌膠防雨電源;

　　2 types of the LED driver used for landscape lighting come into being based on the above factors-natural cooling semi-glue rain-proof LED driver and fan cooling non-gluing LED driver.

　　設(shè)計性能比較

　　Comparison of these designs

　　注：以下僅在同一生產(chǎn)水平下對結(jié)構(gòu)設(shè)計進行比較，因為同樣的設(shè)計，不同廠家由于參數(shù)、工藝、元器件等不同，最終產(chǎn)品穩(wěn)定性也會有較大差異。

　　Note: The structural design is only compared under the same production level. Because different manufacturers have different parameters, processes and components for the same design. Thus the stability of the final product will be greatly different.

　　注：紅色字體為劣勢，綠色字體為優(yōu)勢�？偨Y(jié)：在相同生產(chǎn)工藝水平下自然冷卻半灌膠防雨電源更可靠。但由于沒有風機強制散熱，該結(jié)構(gòu)要求產(chǎn)品本身發(fā)熱低、導熱好，對企業(yè)技術(shù)及生產(chǎn)工藝有更高的要求。如電路設(shè)計要求能達到更高的效率(效率越高，發(fā)熱越低)。

　　Note: The red font is the disadvantage, and the green one is the advantage.Conclusion: the natural cooling semi-glue rain-proof LED driver is more reliable under the same production technology level.The driver itself is required to have low heat, good heat conduction and heat dissipation, which can be also regarded as higher requirements on the technology and process of enterprises. Such as circuit design: the higher the efficiency, the lower the heat.
