While developing fluorescent lamps, people have not forgotten the improvement of incandescent lamps. In 1959, an American named Friedrich discovered that the iodine was filled in an incandescent lamp, and the tungsten atoms sublimated and attached to the wall of the lamp were sent back to the tungsten wire, which not only controlled the sublimation of the filament. Moreover, the temperature of the filament can be greatly increased, and light similar to sunlight can be emitted. The lamp thus produced is called a tungsten iodine lamp.

The iodine-tungsten lamp has the characteristics of high brightness and long life. A 1000 watt iodine-tungsten lamp is equivalent to the brightness of a 5000 watt ordinary bulb. With the deepening of the research, it has been found that some compounds of halogen elements can be better filled into incandescent lamps, for example, hydrogen bromide is charged into incandescent lamps, and bromo-tungsten lamps are made more than iodine-tungsten lamps. To be good, this produces a variety of tungsten halogen lamps. Tungsten halogen lamps are suitable for workshops, theaters, stage, studios, etc. When we saw TV reporters shooting TV news, they held a very bright light source in their hands, that is, tungsten halogen lamps. Its disadvantage is that the heat radiated is very large, and sometimes it can even be used to bake objects.

The utility model belongs to an iodine tungsten lamp holder. The utility model is mainly composed of a main lamp holder, a connecting member, a left and a right lamp holder, a reflector and a reflector fixing frame thereof, and corresponding notches for mounting the lamp tube are respectively arranged in the left and right lamp holders, in the notch A screw hole is arranged between the end of the lamp holder, and a screw for fixing the lamp tube is installed in the screw hole; and a terminal block and a terminal cover are provided at the other end of the lamp holder. The main advantages of the utility model are: safety, fast lamp replacement, fast heat dissipation of the lamp legs and reduction of parts.

Slacklines

A slack line/gibbon slackline is a thin piece of webbing, usually 1 to 2 inches wide, is stretched between two trees using a slackline ratchet.

The line is stretchy and unstable under your feet, so it is hard to walk on. It is a great way to improve balance.
