Description

Bulb

The utility model relates to bulb.

After the 1880's, Edison applied for first relevant electric light patent of night illumination, human backward 120 in the period of because prominent the flying into the step of science and technology, the various lighting apparatus that utilizes various physical principle exploitations to form is used for decorating night, and light has become primary condition indispensable among the human lives around here.The basic principle of bulb is can be to this resistance heating during through a resistance circuit when an electric current, and heating power is W=V ²/ R, wherein V is the voltage drop on the circuit, R then is the resistance of this circuit; Object has a characteristic, and to be object itself can send the radiant light of certain wave-length coverage with the temperature difference, as: human body sends black body radiation after infrared ray, the heating etc. under the room temperature; So if select the material of a certain material, pass to electric current it is heated to suitable temperature, as: tungsten filament be heated to about 3000 the degree, if chemical reaction does not at high temperature take place and changes its character in this material as yet, then this material can suitably send light wave, if this light wave drops on visible region, just can be used for as lighting apparatus.Shown in Figure 1 promptly is the structure chart of general modal bulb 10.

After adopting these lighting apparatus in a large number in the life; human gradually by experience accumulation in life; this simple illumination bulb is added protective device; can prolong the useful life of bulb on the one hand; more can avoid on the other hand because the unexpected injury that the carelessness that electrical equipment uses causes is used the excessive fire that causes etc. as electrical equipment.The bulb of improveing with safety device as shown in Figure 2.The fuse unit 25, one that the basic structure of these bulbs 20 comprises a heat filament 23, a protection is the insulation ball 24 (being generally glass material) of usefulness fixedly, and couple of conductor 22; More than device covers with a transparent outer cover 21; Bulb put in order for: two leads 22 stretch in the glass bulb, and shape is colluded in generally making foremost of two leads 22, and hook a heat filament 23 in the middle of two leads; Secondly, install a fuse 25 additional below filament 23, the main purpose of this fuse 25 is to be used for protective circuit, and when this bulb was used for a cluster of lamps, ornamental, when the some bulbs in a cluster of lamps, ornamental were damaged, remaining bulb also can continue shinny in the cluster of lamps, ornamental.Lead 22 is fixed on the insulation ball 24, afterwards, between heat filament 23 and insulation ball 24, is wound with a fuse 25, constitute the bulb 20 that generally has protective device.

In above-mentioned bulb 20; fuse 25 twines; use regular meeting that the loosening and ineffective problem of fuse takes place in daily life; if bulb needs usually to move (as: decorative lamp that uses on Christmas Day); then easier of vibrations make that the easier generation of fuse that is positioned in the bulb on the lead is loosening, cause loose contact.

Main purpose of the present utility model is to improve previous bulb, and a kind of more firm bulb of connection that can make between fuse and the lead is provided, and this bulb is more durable and can be shockproof.

The purpose of this utility model is achieved in that a kind of bulb, comprise that one is used for covering and fixedly shell, a light-emitting component of light-emitting component, this light-emitting component comprises: a pair of lead, that extends to this enclosure from this enclosure is in order to be fixed on this insulation ball to the centre of lead, and this insulation ball is positioned at this light bulb base top position; One is connected this to a heat filament on the lead and a fuse, and this heat filament is positioned at this insulation ball top, and this fuse is connected this top to lead, by a pair of collude to hook compress.

The utility model is owing to be connected the top of two pairs of leads with fuse, by a pair of collude to hook compress, make to be connected more firmly between fuse and the lead, can in the process of carrying, not become flexible because shake.

Relevant concrete structure of the present utility model describes in detail among the embodiment below.

Fig. 1 for existing not with the structure chart of the bulb of fuse.

Fig. 2 is the structure chart of the bulb of existing band fuse.

Fig. 3 has the structure chart of the bulb of protective device for the utility model.

As shown in Figure 3, the utility model comprises that a heat filament 33, a fuse 35, couple of conductor 32 and are used for fixing the insulation ball 34 of two leads, and the outside is covered by a shell 31.

Bulb of the present utility model has a shell 31, and this shell 31 can be glass or synthetic hard plastic material etc., is used for the element that bulb is luminous to wrap in wherein and fix it.Shell 31 can be general clear glass, also can be to be used for various water white transparency or the transparent hard plastic material translucent or that have color that decorative lamp is used.This shell 31 with the bulb encapsulating luminescent element therein, light-emitting component extends to the outside of shell 31 by couple of conductor 32, can be used for being connected on the power supply unit, and the power supply of the luminous needs of bulb is provided.Comprise one group of bulb light-emitting device in the inside of shell.In addition, this lead 32 is with general material commonly used, for example: the copper wire of plating magnesium is made.

The structure of this bulb light-emitting device is: couple of conductor 32, extend to shell 31 inside from shell 31 outsides, and definition lead 32 is the bottom of bulb with shell 31 junctions, and opposite, promptly be called the top at the other end of the lead 32 of shell 31 inside.Above near bottom position (about 20mm place), with two lead fixed and separate, cause short circuit to avoid the lead distortion to be in contact with one another by an insulation ball 34; This insulation ball material can be glass, pottery etc., and shape is gone back other shapes except that spherical.Extend to certain-length (distance of about 7mm) along lead 32 toward insulation ball 34 tops, connect a heat filament 33 between two leads, this heat filament 33 can be heated and emit beam after the power supply on logical.Extend to the top of lead 32 along past again heat filament 33 tops of lead 32, it is connected with a fuse 35 apart from the generally about 3.5mm of heat filament place; This fuse 35 is connected this top to lead, is hooked by a pair of colluding, and compresses this hook arrangement, to increase the fastness of this fuse 35; In addition, this fuse 35 is used for protective circuit, allows this bulb be useful in the cluster of lamps, ornamental, even some bulbs damages are arranged in the bulb, all the other normal bulbs can operate as normal.Must be noted that the above-mentioned size that provides be with general Christmas Day employed bulb sizes be example, be not inevitable length.

By such assembling, fuse 35 connects between two leads 32 can be more firm, can not become flexible because of vibrations in the process of carrying.
