Abstract

The utility model relates to an underwater color electric discharge lamp and sealing assemblies thereof. The utility model is characterized in that an electric discharge tube of the underwater lamp is provided with a starting electrode; a resistor is connected in series between a positive pole and the starting electrode; special sealing structures are respectively adopted in an electric discharge ballast and an electric discharge trigger; the hot vulcanization process forming integration is adopted at the connecting position of cables and each seal assembly. The utility model has the characteristics of quick underwater lamp start-up, reliable assembly seal and convenient detaching and changing. The utility model is suitable for the decorative illumination of various natural and artificial water view spots. Because having the characteristic of quick start-up, the utility model is suitable to be matched with a musical fountain.

Description

Underwater colour electric discharge lamp and sealing assemblage thereof

The utility model relates to colored discharge lamp and water-stop assembly thereof under water.

Halide gas discharge lamp is used for having the light efficiency height under water, far firing range, bright characteristics, start difficulty but exist simultaneously, match appliance seals the problem that difficulty is installed in water, if will be such as ballast, triggers etc. are installed on the bank, because described assembly is too far away from lamp, under voltage situation on the low side, start difficulty more.Though exist in the prior art and the sealing ballast of lamp adapted under water, because trigger is a consumable accessory, being sealed with ballast changes and reseals difficulty.

The purpose of this utility model is to provide a kind of startup fast, and sealing is reliable, changes colored easily discharge lamp and underwater sealing assembly thereof under water.

Above-mentioned purpose of the present utility model is to realize by such technical scheme: promptly the utility model comprises discharge lamp and guard shield thereof, ballast, trigger and stube cable, wherein discharge lamp comprises discharge tube and bracing frame thereof, be coated with the reflecting layer at discharge lamp glass bulb inwall, cable is connected with discharge lamp by sealing rubber cover; Feature of the present utility model is: described discharge tube is the halogen gas discharge tube with starting electrode, between its anode and starting electrode, be serially connected with resistance, the ballast of discharge lamp is positioned at seal box, add the dividing plate that is stamped cable-through hole on it, and be installed with the Seal of Cables serum cap, between described dividing plate and lid, be filled with epoxy resin layer; The trigger of discharge lamp is positioned at sealing drum, and its lead-out wire port is plugged with and penetrates the Seal of Cables rubber stopper, and is provided with the hold-down mechanism of rubber stopper; Stube cable and described caulking gum lid, or sealing rubber plug, or caulking gum is enclosed within the sealing integral body that the junction is the hot vulcanization process shaping.

Said structure of the present utility model can further specify by accompanying drawing:

The utility model has following accompanying drawing:

Accompanying drawing 1 is the structural representation of the utility model discharge lamp,

Accompanying drawing 2 is the cut-away view of the utility model discharge lamp sealing ballast,

Accompanying drawing 3 is the schematic diagram of the utility model discharge lamp sealing trigger.

Referring to accompanying drawing: the halogen gas discharge tube 2 that has starting electrode 4 among Fig. 1 is fixing by support 10, glass bulb inwall tool reflecting layer (21), can make the light source orientation projection, resistance 5 is connected between the anode and starting electrode of discharge tube, the ballast of discharge lamp is by seal box 13, dividing plate 14, caulking gum lid 11 and epoxy resin layer 12 sealings; The trigger of discharge lamp is by sealing drum 18, sealing rubber plug 8 sealings, wherein sealing drum outlet port has internal taper, plug 8 has external taper, pressing plate 17, stud 15 and nut 16 are formed the hold-down mechanism of plug, pressing plate is positioned at the plug outside, by stud and nut the plug push-tight is fastened between two pressing plates.Stube cable 7 is the sealing integral body 6 that hot vulcanization process is shaped in the junction with described seal.

The utility model is owing to the effect with above-mentioned its generation of structure is conspicuous, one, owing to adopted the discharge tube of tape starting electrode to make light source, when open-circuit voltage just has been added on negative electrode and the anode, because the existence of starting electrode, make the rapid Discharge illuminating of fluorescent tube, because the existence of resistance, the discharge back starts extremely ineffective; Its two, can make ballast and trigger with the discharge lamp adapted have good sealing, guarantee their long-term works under water, break down and also be convenient to change.
