What are the commonly used lamp bases at present?

From the installation point of view, can be divided into bayonet and screw etc., from the material into bakelite, plastics, metals, ceramics and other materials, such as E27 is usually used lamp energy-saving lamp screw socket lamp holder is the most common, and fluorescent lamp is usually called the T8 lamp or T5 lamp and so on, according to the use some environmental protection class up to IP68 holder at the time of purchase, please according to the need to develop IP protection level corresponding to the lamp holder (waterproof socket), usually will use IEC (IEC) safety certification, classification of lamp holder:

E14, E27, E12, E26 and other E at the beginning is usually: screw mouth lamp holders, GU10 and other GU refers to the beginning of our daily bayonet type, GU: G said the lamp type is inserted, U said the lamp part of the U The number followed by the number indicates the center distance of the lamp hole (in millimeters "mm").

MR16, MR11 to MR at the beginning of the direct-type local lighting is a small spotlights commonly used in this lamp holder, usually small spotlights with two pins easy to install. MR16, GU10 is their lamp holder is different, PAR30, 38 is different in diameter, are the world's unified standards and names, they are lamp cups, spotlights of the name, each suitable for different ceiling lamp holder. MR16 in the lighting industry refers to the maximum diameter of 2 inches with a multi-faceted reflector lamps, MP11 is smaller than the MR16 lamps. MRMR: Multi-face Reflect, multi-faceted reflector (lamp cup), followed by the number of lamp cup diameter (unit is 1/8 inch), MR16 diameter=16×1/8=2 inches≈50mm

  PAR lights generally PAR30 PAR36 PAR46 PAR56, the volume is long and short, also known as downlight, light beam, used to illuminate the stage, dynamic color, etc., is the stage of the common lamps, because the power consumption is relatively large, and there are baked Feeling, and now gradually replaced by LED PAR lamp. AR111 / AR70 is aluminum cold reflective halogen spotlights E27, E14 refers to the ordinary screw cap lamp cap size, E27 is our usual incandescent lamp, E14 is smaller than it One, much larger than E27, and E40. G12 is a single-ended tubular metal halide bulb.

目前常用的灯头型号有哪些？

从安装方式来看，可以分为卡口、螺口等方式，从材料分为电木、塑料、金属、陶瓷等材料，通常用的灯座如E27是最普遍的节能灯螺口灯座，而配合日光灯的灯座通常称为T8灯座或T5灯座等等，另根据使用环境有的灯座防护级高达IP68，在选购时请根据需要制定相应的IP防护级灯座（防水等），通常用灯座会用到IEC（国际电工委员会标准）安全认证，灯座分类：

E14、E27、E12、E26等E开头通常为：螺口灯座，GU10等GU开头的指的为我们日常用的卡口式，GU：G表示灯头类型是插入式，U表示灯头部分呈现U字形，后面数字表示灯脚孔中心距（单位是毫米“MM”）。

MR16、MR11以MR开头的是直插式局部照明的小射灯常用这种灯座，通常小射灯有两个插针安装方便。MR16, GU10是他们的灯座不同，PAR30,38 是直径不同，都是世界统一的标准和名称，都是灯杯，射灯的叫法，各适合不同的天花灯的灯座。MR16 在照明行业里指最大外径为2英寸的带多面反射罩的灯具， MP11就是比MR16小一点的灯具,。MRMR：Multiface Reflect，多面反射（灯杯），后面数字表示灯杯口径（单位是1/8英寸），MR16的口径=16×1/8=2英寸≈50mm .

  PAR灯一般有PAR30 PAR36 PAR46 PAR56，体积有长有短，也叫筒灯，照射光束，用来照明舞台、动感换色等，是舞台上常见的灯具，因为耗电比较大，而且有烤的感觉，现在逐渐被LED PAR灯取代 　　AR111/AR70是铝质冷反光卤素射灯　　E27、E14是指的普通螺口灯头的灯头大小，E27就是我们平时用的白炽灯的灯头，E14就是比它小一号的，比E27大的还有E40。G12是一种单端的管形金属卤化物灯泡。

What is the difference between ceiling light and down light?

Ceiling light and down light are widely used in various interior projects, qianshenglight can provides you high quality ceiling light and down light, but their differents are below:

1, Different installation positions

The first difference between ceiling light and down light is installation position. Down light installation is usually installed or concealed in two ways, but no matter what way to install, it is generally located on the edge of the ceiling, this is a mosaic of the lamps, always hidden in the corner of the edge , The projection of the light, the direction down, you can mix with different bulbs, reflectors, shutters and other external components, to increase the projection effect of the downlight, occupy the space range is relatively small, belonging to the kind of contrast space atmosphere. But for ceiling light, most are used for indoor decoration, the most important is the use of LED ceiling light, and its decorative effect is the bedroom warm and romantic.

2, Different types

The second difference is the types. Strictly speak, ceiling light is a type of down light, and down lights are generally belong to the energy saving effect, ceiling lights are mainly used for decoration, but now it also can be used the new LED light source to increase the luminous efficiency of ceiling light, playing a role in energy conservation and environmental protection. Ceiling lights are mainly decorative stronger, down light is mainly played a role in the lighting, because the function and characteristic of different, so they will make changes in the use.

3. Different illuminant

The most difference between ceiling light and down light is the Luminous body. Why? Because the light source of the down light is LED light source, and the light bulb as a light carrier. But for ceiling light, the decorative effect of the ceiling is relatively strong, because its inside uses LEDs as a power light Of the carrier, this is the biggest difference between ceiling light and down light from structure. In fact, there are many differences between ceiling light and down light, but whether it is a ceiling light or down light, they are all the main furniture of the main home furnishings.

Issues related to LED street light inductance

 The LED street light market, the basic use of HID light source with flip flops and inductance ballast model. This model although existing energy efficiency is low and the strobe. However, the use of electronic drive circuit LED street lights, in the field when the use of lighting, the threat of its plasticity is an important aspect of the problem of lightning.

Because of the lightning in the air is a broad spectrum of radio waves, and the overhead LED street lamp power supply lines, can be very good to receive radio waves. Receiving two power lines from the same lightning radio waves, to drive circuit in terms of is belongs to the common mode interference signal, the common mode interference of up to hundreds of volts to thousands of volts, it is easy to breakdown driving circuit of EMC connected capacitor or smaller (shell) clearance, resulting in damage to the drive circuit.

Also due to China's power supply line three-phase four wire system with neutral line connected to the polarity of the power supply, so in two overhead power transmission line segments, the moment of radio waves in the induction lightning, due to the different of the two power cables on the instantaneous impedance for the two power cables between a difference mode interference voltage and the instantaneous differential mode interference voltage can also be reached hundreds of volts to 3000 many volts. This voltage tend to breakdown drive circuit in the power rectifier diode and the printed circuit board of different polarity electrode clearance, LED controller will also make damage to a driving circuit.

To solve this problem, the input of the driving circuit must be in the LED, and then the fast response of the voltage sensitive resistor is connected in order to ensure the discharge of the differential mode interference. Due to lightning induced interference is repeated many times, when the interference voltage is high, the varistor instantaneous guide through vent discharge current can be large, so the varistor should not only have rapid response ability, should also be equipped with instantaneous turn-on tens of AMPS discharge capacity and can not be damaged. In addition to the varistor, LED drive circuit of input should also combined with the protection of conduction interference (EMI), design composite LC network, so that the LC network can not only hinder internal EMI of power leakage, and obvious inhibitory effect on lightning interference signal.

And LED drive circuit at each point of the clearance should be maintained at more than 7mm, EMI protection grounding capacitance and driving circuit of insulation strength, should be reinforced insulation (4V+2750V) and so can the LED drive circuit has good resistance to differential mode and common mode of lightning induction.

How to choose LED strip lighting?

With the improvement of people's living environment requirements, to save power and long life LED strip lightswith known, become more and more families in the decoration of the new house the necessary choices, however, in the purchase of LED strip lights with time, You have to keep their eyes open, beware of traps and errors. Because the market is flooded with a lot of low-quality LED lights, but we can choose to go through the following methods:


1, see the solder.
A formal manufacturer with using SMT SMD technology, used in the production of solder paste and reflow process. Therefore, the LED strip lights with solder joint relatively smooth and not much amount of solder, solder joint is extended arc from FPC to LED at the electrode pad. The uniform version of the cottage LED strip lights with solder solder volume was a dot wrap welding feet, also will have varying degrees of tin tip appears, this is a typical phenomenon in the manual welding.

2, Looking FPC quality.
FPC points of Copper and copper rolling, Bonded Copper foil is projecting, and then look at the connection from the FPC pad see it. And rolled copper FPC is close and connected as a whole can be bent and will not appear pad off phenomenon. Bonded Copper pad will appear if bent too much off, maintenance temperature is too high will cause pad off.

3, See LED strip lights with the cleanliness of the surface.
If the LED lamp produced by SMT technology, the surface cleanliness is very good, can not see any impuritie and dirt. But if by hand welding process for the production of cottage version of LED lamp belt, the surface no matter how cleaning will residual traces of the cleaning of stains and, at the same time the surface of the FPC will have residual flux and tin slag.4, Look at packaging.
Regular LED strip lights will use anti-static packaging roll tray, usually 5 m or 10 m roll of a roll, and then out again with anti-static moisture-proof bag sealed. The cottage version of LED lights because of the cost savings, while the use of recycled roll tray, then there is no anti-static moisture-proof bags, look carefully roll tray can see the appearance of a label when clear traces and scratches.
5, Look at the label.
Regular LED strip lights with bags and roll above the disk will have a printed label instead of printing labels. The cottage version of the label is printed, as well as specifications and parameters are not unified.
