Abstract
Disclosed is an illuminating bulb of waterproof bulb series, comprising a bulb holder (1), a filament and filament frame (2), a glass tube (3), a glass outer tube (4), an air layer (5) and an aerating tube (6). The advantage of the utility model is that first, compared with the common bulb, the utility model has a long life span in the environment of rain dripping and dampness. Second, even if the glass tube is blown out, for the glass outer tube is thick, the utility model can bear a larger destructive power, and the glass outer tube is still intact, which can prevent the insecure hidden troubles led by bulb blowing out.
Description
The utility model relates to a kind of illuminator lamp bubble, belongs to low-voltage electrical apparatus.
The kind and the purposes of bulb are various.With regard to illuminating bulb, the illuminating lamp of (1) open-air (open air), when raining, the drench that drenched with rain unavoidably has a strong impact on the useful life of bulb, and causes the bulb explosion easily.Now the way that adopts is bulb the higher authorities lampshade to be installed, to avoid rainwater directly dripping to bulb.If a kind of bulb of design even suffer rainwater dripping, can not influence useful life yet, can not cause the bulb explosion, have practical significance.(2) down-hole, humidity, the bulb rapid wear is explosive, shortens greatly the useful life of bulb on the one hand, and the bulb explosion may be ignited inflammable and explosive substances on the other hand, causes dangerous situation even the condition of a disaster.If a kind of bulb of design, moistureproof damp proof excellent performance, its practical significance is bigger.
The purpose of the utility model designs just releases a kind of lighting bulb---Water-proof lamp bulb that uses under the like environment such as above-mentioned that is suitable for.
For this reason, the technical solution of the utility model is: steep the certain spacing of being separated by between the outer bubble of glass envelope and glass, formation air layer outside the glass envelope of original bulb adds cover glass.Glass breather pipe of break-through on the bubble outside glass allows the atmosphere outside the outer bubble of air layer and glass communicate, and makes the inside and outside layer air pressure of the outer bubble of glass equal.The thickness of the outer bubble of glass is greater than the thickness of glass envelope.
The Water-proof lamp bulb advantage that the utility model is released is outstanding, and the one, at rainwater in the dripping or wet environment, than prolonging in useful life of common bulb; The 2nd, even the glass envelope explosion because the outer bubble of glass is thicker, can be born bigger destructive power, the outer bubble of glass is still intact, can prevent the bulb explosion and the hidden danger that causes.
Fig. 1 is the utility model structural representation.As shown in the figure, the utility model by lamp holder (1), filament and filament frame (2), glass envelope (3), glass steep (4), air layer (5) outward, breather pipe (6) is formed.Lamp holder (1) is shape of threads or socket shape.Filament and filament frame (2) are positioned at glass envelope (3), and the top of filament and filament frame (2) is fixedly installed in the lamp holder (1).On lamp holder (1), be furnished with the joint of filament and power supply.Glass envelope (3) is fastening being tightly connected with lamp holder (1).Glass steeps (4) outward and adds and be enclosed within outside the glass envelope (3), and glass envelope (3) and glass steep outward and is air layer (5) between (4), and glass steeps the upper end of (4) and the lower end of lamp holder (1) and the upper end of glass envelope (3) outward and is fixedly linked together.Breather pipe (6) passes glass and steeps (4) outward and steep (4) outward with glass and be linked to be integral body, and air layer (5) is communicated with atmosphere.
Breather pipe (6) is made of glass.
Glass steeps the thickness of the thickness of (4) greater than glass envelope (3) outward, selects for use the bigger glass material of intensity to make.
Claims (3)
1, Water-proof lamp bulb, by lamp holder (1), filament and filament frame (2), glass envelope (3), glass steeps (4) outward, air layer (5), breather pipe (6) is formed, lamp holder (1) is shape of threads or socket shape, filament and filament frame (2) are positioned at glass envelope (3), the top of filament and filament frame (2) is fixedly installed in lamp and closes in (1), on lamp holder (1), be furnished with the joint of filament and power supply, glass envelope (3) is fastening being tightly connected with lamp holder (1), it is characterized in that glass steeps (4) outward and adds and be enclosed within outside the glass envelope (3), glass envelope (3) and glass steep outward and are air layer (5) between (4), glass steeps the upper end of (4) and the lower end of lamp holder (1) and the upper surface phasing of glass envelope (3) outward and connects together, breather pipe (6) passes glass and steeps (4) outward and steep (4) outward with glass and be linked to be integral body, makes air layer 5) communicate with atmosphere.
2, the Water-proof lamp bulb of narrating according to claim 1 is characterized in that glass steeps the thickness of the thickness of (4) greater than glass envelope (3) outward.
3, the Water-proof lamp bulb of narrating according to claim 1 is characterized in that breather pipe (6) makes of glass.
