Abstract

The utility model discloses a split-type explosion-proof energy-saving lamp. A ballast box is connected in series on a leading wire tube at the top part of an explosion-proof lamp cover; the front side of the box is a box cover fixed by screws; the box bottom is provided with a circuit board fixing hole. When the box is used, the core control component of the explosion-proof lamp-the ballast is inserted in the box. Because the ballast box and the lamp cover are split structure, only very small part of the heat of the lamp is passed to the ballast box. Thus, the main components can be ensured that the service life can not be shortened because of overheated working conditions.

Description

Split type explosion-proof electricity-saving lamp

The utility model relates to a kind of light fixture, especially split type explosion-proof electricity-saving lamp.

In existing explosion-proof lamp, have two kinds the most commonly used: a kind of for the explosion-proof type fluorescent lamp, another kind is the explosion-proof type incandescent lamp, no matter be that in above that is a kind of, be used for inflammable and explosive workplace because be, circuit and components and parts sealing, make flammable explosive gas directly not touch circuit and components and parts are indispensable, the technological means of being taked is that (fluorescence) lamp is arranged in the cloche, though doing the problem of sealing is so effectively solved, but the luminous produced simultaneously heat of lamp also is difficult for outwards scattering and disappearing, work under the overtemperature state to making light fixture, the ballast box of existing anti-explosion fluorescent lamp is exactly and the lampshade integrative-structure that components and parts can shorten the life-span because of overheated, have so not only influenced use but also have caused unnecessary loss.

The purpose of this utility model provides a kind of split type explosion-proof electricity-saving lamp, to reach lampshade and ballast box splits installation, effectively prevents to cause components and parts premature damage in lamp and the ballast box because of overtemperature.

Realize that the purpose of this utility model technical scheme is achieved in that the mode that adopts ballast box and Explosion-proof globe split to assemble reduces the heat that is delivered in the ballast box, components and parts trouble free service in so just can guard box, concrete structure is such, the ballast box casing that is rectangle, just and by a plurality of screw one case lids at the bottom of the case, there is the wiring board fixing hole the inside, the ballast box upper lateral part has the tapped fairlead of going up, and the following side is with externally threaded fairlead down to link to each other with Explosion-proof globe.

Owing to adopted above technical scheme, the heat that lamp is produced has only seldom, and a part passes to ballast box, can guarantee that the controlling parts in the ballast box is operated in the proper temperature environment, unlikely because of overheated operational environment causes the shortening in useful life, reduced unnecessary components and parts consumption.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the front view of the utility model one embodiment.

Ballast box 4 is rectangular box in Fig. 1, and the front is a case lid 5 that has certain thickness, shape and casing to match, and the case lid 5 among Fig. 1 is partly cut-away, and the wiring board fixing hole 6,1 that exposes on being positioned at the bottom of the case is an internal thread.It is semi-transparent less internal thread hole at the bottom of the case, and dotted line is drawn in letter in the drawings, and the wiring board of ballast can be fastened on the bottom of ballast by four Screws.4 four jiaos of ballast boxes and stage casing are provided with screwed hole 3, are used for firm case lid 5, and 4 fattens of case lid 5 and ballast box or airtight and watertight padding sealing can prevent from that fuel gas from scurrying into wherein to cause danger.Outside pars intermedia is provided with a tapped fairlead 2 of going up on the ballast box 4; be connected with the distribution pipe with it; establish one again at the following outside of ballast box 4 correspondences pars intermedia externally threaded lower draft tube 7 is arranged; make it to connect into a seal with Explosion-proof globe 8; electronic devices and components in the ballast box have obtained effective protection like this, and sealing property has also obtained good solution simultaneously.

Claims

1, a kind of split type explosion-proof electricity-saving lamp, it is made of lampshade, ballast box etc., it is characterized in that: ballast box (4) assembles with lampshade (8) split, and is connected by the following fairlead (7) in the outside under the ballast (4).

2, a kind of split type explosion-proof electricity-saving lamp according to claim 1 is characterized in that: ballast box (4) is gone up outside pars intermedia and is provided with a tapped fairlead (2) of going up, and the corresponding portion in the following outside is provided with one externally threaded fairlead (7) down.

3, a kind of split type explosion-proof electricity-saving lamp according to claim 1, its feature also is: four jiaos and stage casing at ballast box (4), be provided with screwed hole (3), be provided with semi-transparent internal thread hole (6) at the bottom of the case.
