Mechanical strength,Torsional torque Perform the following torque test, the cap should be firmly bonded to the lamp body or the lamp used to precession or spin out the site: Lamp holder B22d ............................................................................................................ 3 N · m Lamp holder E27 ............................................................................................................... 3 N · m Torque should not be suddenly imposed, and should be gradually increased from zero to the specified value. Not used for bonding of the lamp is fixed, the lamp cap and the lamp allows a relative movement between, but should not exceed 10 °. Mechanical strength test, the lamps shall conform to the requirements of electric shock prevention (see Chapter 6). Cap temperature rise In accordance with the QB / T 2512 Measuring finished lamp cap temperature rise △ ts when its temperature during the start of the lamp, stability and stabilization period of time after shall not exceed the following values: B22d ................................................. .................. 125 K E27 ................................................. .................. 120 K The temperature rise and 60 W (maximum power) incandescent temperature rise the same as incandescent prevent overheating. Incandescent lamps heat resistance heat test source (HTS) lamps test. All tests shall be conducted using the rated voltage. If the lamp voltage range marked only should be used the average of the voltage range of the test, but the voltage range of the upper and lower limit values ​​of the difference between its average voltage should not exceed 2.5%. For a wide range of lamp voltage, the test is used when the highest value in its scope. Heat resistance Self-ballasted electrodeless fluorescent lamps shall have sufficient heat resistance. External shock light insulating member and the fixed member of the insulating member should be charged with sufficient heat resistance. Shown in Figure 4 using the ball pressure test apparatus to test its eligibility. Test shall be carried out in the heating chamber, the inside temperature should be lower than in Chapter 9 of the parts normal operating temperature 25 ℃ ± 5 ℃. For a fixed charging member is an insulating member must be at least 125 ℃, other components should be 80 ℃. The surface should be level tested components added together, the 5 mm diameter steel ball beat of 20 N on the surface of the test part. Prior to testing, the first test load and the support device in a heating chamber heating time sufficient to ensure that they reach a stable test temperature....

Lamp base Short, there are two scenarios: one, a different phase of the phase line collide, phase short circuit. 2, phase and ground (zero line) collide, shorted to ground. the current in the circuit from the power of the electrical device through the back end of the other end of the power the circuit. Chiang electrical circuit if for some reason cut off or is disconnected, the current can not flow in the circuit, the circuit does not form a loop, called circuit. Both ends of the power supply without any electrical equipment connected directly called shorted wire. Short circuit, the circuit will be very large current, called the short-circuit current. When a short circuit occurs, the short-circuit current may increase the lead to far exceed the allowable current limit, resulting in intense heat conductor, and even burned electrical equipment, causing a fire....

Lamp base is the end of the line connected to the lamp, the lamp used for the interface to be used with caution. The main use of electric light lamp holder naming method. The end cap is a light bulb is the light source and an external power supply connection part of the light source lamp electrical connection through the produce luminescence. Light body including lamp beads, light bulbs, fluorescent tubes, which also includes a straight tube and tube bending tubes. LED light source is mainly in the form of LED lights, light bulbs are generally incandescent, fluorescent, halogen, etc., mainly common fluorescent lamp. Most of the lamp cap form, because no head lamp beads, beads small lights connected together through another structure, the role of these structures is equivalent lamp, the specific form of the fixture design. The straight sides of the lamp plug cap where the role of representing. According to the material can be divided into: 1 bakelite lamp holder 2 ceramic lamp holder 3 Metal Base: divided into aluminum lamp, brass lamp 4 wooden lamp holder...

E26 specification called "Medium" (Medium porcelain lamp holder meaning). E26 and E27 have been designated as the IEC lamp holders standard. The lighting system of each country because the mains voltage vary, E26 mostly mains voltage of 100V ~ 120V countries used, E27 for the 220V ~ 240V multi-national use. So the market seen E26 bulbs are mostly fixed voltage of 100V ~ 120V; E27 mostly 220V ~ 240V, as well industrial machinery with safety bulb 36V,. E26 and E27 two kinds of outer diameter of the thread is close, the difference is different depths E thread valley, E26 relatively shallow. Another E27 base of the neck longer than the E26, so the two should match their specifications lamp holder. If E27 lamp screwed into the lamp holder E26, you will find a lot of neck exposed metal experience (likely to cause an electric shock). E27 In addition to China, in Europe, are also common. E26 in North America, Japan, more generic....
