Low cost explosion-proof high pressure single end halogen decorative lamp
Conventional single-ended halogen bulb is generally composed of quartz tube, filament, glass bead holder supporting the filament, lead on the glass bead holder, molybdenum foil encapsulated in the glass, and lamp foot. This structure of halogen bulb, for semi-automatic clamping, exhaust design, if the vacuum degree in the manufacturing process does not meet the requirements, the lamp under the action of high temperature and high electric field, the bulb or parts of the dirty gas will produce an arc discharge between the bulb two leads, leading to infinite increase of current flowing through the outer molybdenum foil. When the current allowed to pass through molybdenum foil is 10-20A, under the action of instantaneous large current, molybdenum foil overload will produce high heat and burn. The melting point of molybdenum is 2620℃, and the glass encapsulating molybdenum foil will burst at 2620℃, causing the bulb explosion.
A low-cost explosion proof type high-voltage single-ended halogen lights, can prevent the explosion by instantaneous large current, assembled with a layer of glass shell, glass shell will halogen lamp bead shield on its isolation with the outside world, this design has high photosynthetic efficiency, safe and reliable, convenient installation, low cost advantages, the update products are ordinary incandescent bulbs.
The high-pressure single-ended halogen lights, including a main body structure, the main body including decorative glass shell and connected with decorative glass shell of lamp holder, decorative glass shell has a core column is installed inside, core column on sealing has two sets of extended upward godet, core column above through thread connection with halogen lamp bead, halogen lights, set up a filament and tungsten fulcrum, filament ends at the bottom of the welding molybdenum foils, The other end of the molybdenum foil is connected with a molybdenum pin, the bottom of the molybdenum pin is connected with a lamp foot, the lamp holder is embedded in the lamp holder electrically connected with the copper eye, the lamp holder is provided with a fuse electrically connected with the copper eye of the lamp holder.
