Reflow soldering must not be done more than twotimes. Do observe necessary precautions for handling a moisture-sensitive device, as stated in the following section.b. Recommended board reflow direction:(i) Leaded reflow soldering:(ii) Lead-free reflow soldering:c. Do not apply any pressure or force on the LED during reflow and after reflow when the LED is still hot.d. It is preferred that you use reflow soldering to solder the LED. Use hand soldering only for rework if unavoidable but must be strictly controlled to the following conditions:- Soldering iron tip temperature = 320 °C max.- Soldering duration = 3 sec max.- Number of cycles = 1 only- Power of soldering iron = 50 W max.e. Do not touch the LED body with a hot soldering iron except the soldering terminals as this may damage the LED.f. For de-soldering, it is recommended to use appropriate double head soldering iron. User is advised to confirm beforehand whether the functionality and performance of the LED is affected by hand soldering.TIMETIMET E M P E R A T U RE11PRECAUTIONARY NOTES1. Handling precautionsFor automated pick and place, Avago has tested nozzle size below made with urethane material to be working fine with this LED. However, due to the possibility of variations in other parameters such as pick and place machine maker/model and other settings of the ma-chine, customer is recommended to verify the nozzle selected.d. Control of assembled boards- If the PCB soldered with the LEDs is to be subjected to other high temperature processes, the PCB need to be stored in sealed MBB with desiccant or desiccator at <5%RH to ensure that all LEDs have not exceeded their floor life of 672 hours.e. Baking is required if:- The HIC indicator is not BROWN at 10% and is AZURE at 5%.- The LEDs are exposed to condition of >30°C / 60% RH at any time.- The LED floor life exceeded 672hrs.The recommended baking condition is: 60±5ºC for 20hrs. Baking should only be done once. f. Storage- The soldering terminals of these Avago LEDs are silver plated. If the LEDs are being exposed in ambient environment for too long, the silver plating might be oxidized and thus affecting its solderability performance. As such, unused LEDs must be kept in sealed MBB with desiccant or in desiccator at <5%RH.3. Application precautionsa. Drive current of the LED must not exceed the maximum allowable limit across temperature as stated in the datasheet. Constant current driving is recommended to ensure consistent performance.b. LED is not intended for reverse bias. Do use other appropriate components for such purpose. When driving the LED in matrix form, it is crucial to ensure that the reverse bias voltage is not exceeding the allowable limit of the LED.c. Avoid rapid change in ambient temperature especially in high humidity environment as this will cause condensation on the LED.d. If the LED is intended to be used in outdoor or harsh environment, the LED leads must be protected with suitable potting material against damages caused by rain water, oil, corrosive gases etc. It is recommended to have louver or shade to reduce direct sunlight on the LEDs.4. Eye safety precautionsLEDs may pose optical hazards when in operation. It is not advisable to view directly at operating LEDs as it may be harmful to the eyes. For safety reasons, use ap-propriate shielding or personal protective equipments.Note:1. Nozzle tip should touch the LED flange during pick and place.2. Outer dimensions of the nozzle should be able to fit into the carrier tape pocket.2. Handling of moisture-sensitive deviceThis product has a Moisture Sensitive Level 2a rating per JEDEC J-STD-020. Refer to Avago Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices, for additional details and a review of proper handling procedures.a. Before use- An unopened moisture barrier bag (MBB) can be stored at <40°C/90%RH for 12 months. If the actual shelf life has exceeded 12 months and the humidity Indicator Card (HIC) indicates that baking is not required, then it is safe to reflow the LEDs per the original MSL rating.- It is recommended that the MBB not be opened prior to assembly (e.g. for IQC). b. Control after opening the MBB- The humidity indicator card (HIC) shall be read immediately upon opening of MBB.- The LEDs must be kept at <30°C / 60%RH at all times and all high temperature related processes including soldering, curing or rework need to be completed within 672 hours.c. Control for unfinished reel- Unused LEDs must be stored in a sealed MBB with desiccant or desiccator at <5%RH.>3.5mmFor product information and a complete list of distributors, please go to our web site: Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies in the United States and other countries.Data subject to change.

LED MR16灯头的详细讲解
MR16（有時稱為MR-16）是一種由眾多製造商所製定的標準規格鹵素反射燈。
現今MR16型式的LED燈也可見到。
MR16燈經常用來代替緊湊型熒光燈或標準白熾燈泡的應用，包括住宅照明和零售照明。
MR16燈最初是被設計用於幻燈機。
他們適合於各種的應用場合，需要從低到中等強度的指向性照明，例如追蹤照明、凹天花板燈、枱燈、吊燈、燈具、景觀照明、零售展示照明和自行車頭燈。
命名由來MR16是一種命名編號，其中「MR」是代表多重反射罩(Multifaceted Reflector)。
16是代表前直徑的長度，為多少單位長的倍數，規定8個單位長為1英吋。
以MR16為例，前直徑是16個單位長，則前直徑是2英吋，即2x2.54cm =5.04cm，口徑約長5公分。
MR16 and MR11 (sometimes referred to as MR-16 or MR-11, rarely MR8 or MR-8) are standard formats for halogen multifaceted reflector light bulbs made by a variety of manufacturers. MR16-compatible LED lamps are also available. MR16 lamps are regularly used in place of standard incandescent light bulbs for applications including residential lighting and retail lighting, while MR11 ones are used in specialty applications. MR16 lamps were originally designed for use in slide projectors. They are well suited to a variety of applications that require directional lighting of low to medium intensity, such as track lighting, recessed ceiling lights(only if not dichroic[citation needed]), desk lamps, pendant fixtures, landscape lighting, retail display lighting and bicycle headlights[citation needed].DesignationMR16 is a coded designation in which MR stands for multifaceted reflector, and 16 is the number of eighths of an inch the front is in diameter. An MR16 is 2 inches (51 mm), an MR11 is 1.375 inches (35 mm).Halogen MR16 characteristicsDesign and constructionHalogen MR16 lamps consist of a halogen capsule (bulb) integrated with a pressed glass reflector. The reflector of an MR16 lamp is 2 inches (50mm) in diameter. The base conforms to bi-pin GU5.3 standard. The compact size of the MR16 allows for much smaller, more discreet fixtures than the incandescent reflector bulbs that pre-dated MR16s.The reflector controls the direction and spread of light cast from the lamp. MR16 lamps are available with different beam angles from narrow spot lights of as small as 7 degrees to wide flood lamps of 60 degrees."MR" refers to multifaceted reflector, indicating that this reflector is usually shaped with multiple small facets. This multifaceted reflector gives a soft edge to the area illuminated by the lamp. MR16 lamps are also available with smooth reflectors, resulting in a sharper fall-off to the illuminated area. "16" refers to the maximum diameter of the lamp in eighths of an inch, 16/8" or 2 inches (5 cm).Dichroic reflectorsIn less-expensive lamps, the reflector has an aluminium coating that reflects all light. In more-expensive lamps, the reflector commonly has a dichroic coating that reflects particular frequencies of the visible spectrum in the direction the lamp is facing, while not reflecting infrared light. By not reflecting infrared light (which produces heat), these lamps reduce the amount of heating of the subject upon which they are focused. The combination of the halogen light source and dichroic coating also means that these lamps provide a high color rendering index and a higher color temperature than standard incandescent bulbs. This makes them well suited to applications where color rendering is important, such as retail display lighting.IEC 60598 No Cool Beam symbolDichroic lamps, however must never be used in recessed lighting as they are a common ignitionsource for building fires.[citation needed] In some countries (e.g. UK, Australia), lamps suitable for use in recessed lighting can be identified by the IEC 60598 No Cool Beam symbol. OperationThe brightness of MR16 lamps can be adjusted when used with appropriate light fixtures and dimmers. However, the color temperature changes significantly when the lamp is dimmed.MR16 lamps produce significant heat, and care must be taken to avoid contact with skin or proximity to flammable materials when the lamp is on or has been on recently.Halogen MR16 lamps are typically more efficient than standard incandescent bulbs, but not nearly as efficient as fluorescent lamps or LED technology. MR16 lamps typically have a life expectancy of 1000 to 3000 hours.With both types of incandescent bulbs, useful life can be considerably shortened if their filaments experience mechanical shock or vibration. Using an electronic transformer with a 'soft start' feature can considerably extend life as it reduces the characteristically high inrush current which occurs shortly after switch-on. Additionally, it can be less strainful on the eyes, giving the pupils more time to react to a sudden increase in environmental lighting level.MR16 lamps, like all quartz-halogen lamps, produce substantial amounts of ultraviolet light. Usually, this must be filtered out. Also, the quartz capsule of the lamp sometimes ruptures ("explodes") upon failure of the lamp. For these two reasons, some MR16 lamps include a cover glass that serves as an integrated ultraviolet filter and explosion shield. MR16 lamps lacking this cover require the use of a fixture that incorporates an external piece of glass specifically designed to provide this protection.Compatible LED replacementsMain article: LED bulbLED MR11, 70 lm/W LED MR16MR16-compatible LED lamps are also available. They are similar in shape to halogen MR16 lamps, and can be used in most fixtures designed for MR16 lamps. The same is true of MR11-compatible LED lamps.Versions of the led lamps have been patented in the UK[citation needed]. Due to the low heat and power consumption, they have been produced from plastic, although this does not affect their efficiency. Their non-polarised AC/DC operation, with current limitation over a wide voltage range (11.5 ~ 18 volts as a standard 12 volt version), allows a wide range of usage.Average rated life, as quoted by manufacturers, is typically 30,000–50,000 hours depending on theproduct in question. This amounts to continuous operation for 1250–2080 days or approximately 24 hours per day, for three to six years.Fixtures designed for halogen MR16 or MR11 lamps that use electronic transformers may need to be retrofitted with LED-compatible transformers. This is because the standard electronic transformers have a minimum power-usage requirement in order to function. Some LED-lamps may be below this usage requirement. Fixtures that use magnetic transformers can generally be used with LED-lamps without modification.LED-lamps from some manufacturers incorporate full wave rectification circuitry into the 'bulb', so that either AC or DC can be used, whilst others require a DC supply and correct polarity.At this time, there are few standards for MR16 and MR11 compatible LED lamps. As such there is a wide variety of designs, varying significantly with regard to beam width, light colour, efficiency and luminous power.Unlike halogen MR16s, LED-lamps often do not have the multifaceted reflectors that give MR16s their precise beam width control. Some rely on the optics of the LED(s) to control the beam width. Some designs may have simple cut-off apertures that limit beam width, or even individual reflectors for each LED.As with other LED lamps available today, the quality and color temperature of the white light produced by such lamps varies. Many tend towards the blue end of the spectrum, being even "cooler"-coloured than fluorescent lighting. Because of this variability, some MR16 and MR11 compatible LED lamps will create significantly more natural looking light than others.The least efficient of these lamps produce about 26 lumens per watt (lm/W), which is similar to the efficiency of halogen MR16s. The most efficient of these lamps available today produce about 100 lm/W, which exceeds the efficiency of compact fluorescent lamps.In terms of total luminous power, such lamps range from being significantly less powerful than their halogen counterparts, to being comparable to the lower power halogen MR16s. The brightest available halogen MR16s are still slightly brighter than the brightest available LED versions.VariationsMR16 lamps most often operate at 12 volts, although they are also available in other voltages. The common 12-volt MR16 lamps therefore require a magnetic or electronic transformer (sometimes misnamed as a ballast) to convert the 120 or 240 volt mains voltage to the very low operating voltage required by the lamp. Note that although halogen MR16 lamps can usually operate on either AC or DC voltage, LED devices require DC voltage and as such will require a rectifier in the unit if AC is to be used.Certain MR16 lamps can operate directly on the mains voltage. These lamps typically use a GU10 turn-and-lock base, so they cannot be accidentally interchanged with low-voltage lamps. As such, they are often referred to as GU10 rather than MR16 lamps. Because of their use of much-finer wire, the filaments of lamps that operate directly from mains voltage are much more fragile than those used in low-voltage lamps.Low-voltage MR16 lamps almost always have ANSI standard GU5.3 two-pin bases. MR16 lamps with an integrated transformer are also available. These lamps have screw bases to fit standard medium-base Edison sockets.Smaller lamps are also manufactured in the less common MR11 and even less common MR8formats, which have reflectors that are 1⅜ inch (11/8" or 35 mm) and 1 inch (8/8" or 25 mm) in diameter, respectively. These smaller lamps appear very similar to MR16 lamps, also featuring similar multifaceted reflectors that are available in a variety of beam spreads. Their smaller size makes possible even smaller fixtures, but limits them to lower powers. MR11 and MR8 lamps have pins placed more closely together, preventing them from accidentally being interchanged with MR16 lamps.Feit Electric produces a compact fluorescent version that can replace an MR16, however this runs only a few watts, and scatters the small amount of light widely, thus is only suitable for limited applications.ANSI designationsA typical MR16 lampThe following ANSI standard codes are used to designate certain power and beam angle combinations for MR16 lamps. Many manufacturers use these standard codes for lamps matching these specifications:ESX: 20 watt, 10 degree beam (20MR16/10°)BAB: 20 watt, 35 degree beam (20MR16/35°)EXT: 50 watt, 15 degree beam (50MR16/15°)EXZ: 50 watt, 25 degree beam (50MR16/25°)EXN: 50 watt, 40 degree beam (50MR16/40°)FNV: 50 watt, 60 degree beam (50MR16/60°)FPA: 65 watt, 15 degree beam (65MR16/15°)FPC: 65 watt, 25 degree beam (65MR16/25°)FPB: 65 watt, 40 degree beam (65MR16/40°)EYF: 75 watt, 15 degree beam (75MR16/15°)EYJ: 75 watt, 25 degree beam (75MR16/25°)EYC: 75 watt, 40 degree beam (75MR16/40°)Note that MR16 lamps are available in many other power and beam combinations than those available above. For this reason, MR16 lamps are also often labeled according to beam spread abbreviations. Note that these while these abbreviations are commonly used, the angles associated with these abbreviations vary slightly from manufacturer to manufacturer. These are typical beam angles for these beam spread abbreviationsVNSP (very narrow spot): less than 8 degrees NSP (narrow spot): 8-15 degreesSP (spot): 8-20 degreesNFL (narrow flood): 24-30 degreesFL (flood): 35-40 degreesWFL (wide flood): 55-60 degreesVWFL (very wide flood): 60 degrees or more。

龙茂微电子开发成功
3×3W大功率MR16射灯
无论在商场或家庭中都广泛采用射灯，以用来照明特定的目标。
原来这种射灯是采用卤素灯，而且它采用了一种已经成为标准的mr16插座。
由于卤素灯的发光效率和白炽灯一样是很低的，寿命也只有2000小时左右，所以理当成为led所取代的对象。
在目前市场上最为流行的mr16型led射灯是3×1w的。
采用mr16的目的是为了便于取代原来的卤素灯，只要拔下插入就可以了。
然而通常卤素灯的功率为50w，最大功率的石英卤素灯可以达到100 w，而最小功率的12v卤素灯也在10w以上。
虽然卤素灯的发光效率很低，用3w的led来代替10w的卤素灯是没有问题的，然而想要用3w的led来代替50w或100w的卤素灯显然是不可能的。
现有的mr16的插座里往往有一个50w的电子变压器，如果只用3w的功率也有点浪费。
所以如果能够有10w左右的led射灯就能取代50w的卤素射灯，也能大大提高原来10w 卤素射灯的亮度。
为此，上海龙茂公司特地开发了一款3×3w的mr16大功率led射灯slm3316，它的外形照片如下图所示。
这个大功率led射灯采用了cree公司的高效3w的白色led。
其色温有两种，slm3316-cw为亮白色，色温在5,800k-6,300k左右，总流明数为450lm。
另一种为暖白色slm3316-w w，其色温在2,700k-2,900k，总流明数为400lm。
这种大功率led射灯的驱动采用了本公司生产的降压型恒流源slm2862j。
这种恒流驱动源可以在12v时驱动3个3w的led，在24v 时还可以驱动6个3w的led，不过因为这个射灯只有3个3瓦的led，所以有点大材小用。
由于这种3瓦led的正向电压在3.5v左右，三个串联以后将会达到10.5v。
所以在电源为1 2vac或dc时，led电流只能达到500ma左右。
而在24vac或dc时，就可以达到700ma。
整个射灯采用铝合金外壳，具有很好的散热性能，这也延长了led的寿命,减少了光衰的程度。
其射角为50度，可以很好地向目标聚光。
该射灯现已进入批量生产。
