Abstract

The utility model discloses an illuminating device and a mated lamp base, relating to an electric light source. The technical proposal of the utility model is an illuminating device comprising a transparent casing; two or more groups of illuminating devices are arranged in the transparent casing; and the mated lamp base comprises an outer interface and a contact terminal; a shift switch is arranged between the outer interface and the contact terminal; one end of the shift switch contacts the outer interface, and the other end contacts the contact terminal; the quantity of the contact terminal correspond to the number of the terminals of the illuminating device. The utility model has the beneficial effects of simple structure low cost and long service life.

Description

A kind of luminaire and supporting lamp holder

Technical field

The utility model relates to a kind of electric light source.

Background technology

At present, the luminaire that people use as incandescent lamp etc., generally comprises transparent outer cover and luminous element.Common structure is, one group of luminous element (filament) is arranged in the transparent outer cover, and the luminaire of this single group luminous element, major defect are that useful life is short.After filament damaged, whole luminaire was promptly scrapped.Next is, the power of this luminaire itself is nonadjustable, and its power adjustments is to realize by dimmer additional on the circuit.Like this, both increase cost, and also can produce harmful electromagnetic interference.

The utility model content

Technical problem to be solved in the utility model is exactly the shortcoming at above-mentioned prior art, and a kind of luminaire and supporting lamp holder with multi-group light-emitting body is provided.

The utility model solves its technical problem, and the technical scheme of employing is that a kind of luminaire comprises transparent outer cover, is provided with 2 groups or 2 groups of above luminous elements in the described transparent outer cover; Supporting lamp holder comprises outer line interface and contact, is provided with diverter switch between line interface and the contact outside; Described diverter switch one end contacts with outer line interface, and the other end contacts with contact; Described contact quantity is corresponding with the luminous element exit.

The beneficial effects of the utility model are, and are simple in structure, with low cost.The luminaire long service life, and have dimming function.

Description of drawings

Fig. 1 is the luminaire schematic diagram of embodiment 1;

Fig. 2 is the circuit diagram of embodiment 1;

Fig. 3 is the luminaire schematic diagram of embodiment 2;

Fig. 4 is the circuit diagram of embodiment 2.

Each component part numbers is among the figure: 11---transparent outer cover, 12---luminous element, 1,2,3,4,5,6---being respectively the exit of each luminous element, 7---public exit of luminous element, L1, L2, L3---represent three groups of luminous elements respectively, 10---diverter switch.

Embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.

The technical solution of the utility model is that a kind of luminaire comprises transparent outer cover 11, is provided with 2 groups or 2 groups of above luminous elements 12 in the described transparent outer cover 11; Every group of luminous element 12 has a pair of exit; Preferred scheme is that described luminous element 12 has a public exit 7; Every group of luminous element 12 power are identical or different; The supporting lamp holder of above-mentioned luminaire comprises outer line interface and contact, is provided with diverter switch 10 outside between line interface and the contact; Described diverter switch 10 1 ends contact with outer line interface, and the other end contacts with contact; The quantity of described contact is corresponding with the luminous element exit; Above-mentioned lamp holder is a bayonet cap; The structure of another kind of supporting lamp holder comprises outer line interface and contact, and described lamp holder is a bayonet cap; Described contact position is corresponding with luminous element exit and bayonet socket position.

Embodiment 1

Referring to Fig. 1.The luminaire that this is routine is provided with L1, L2, three groups of luminous elements 12 of L3 in transparent outer cover 11, every group of luminous element has a pair of exit to be respectively 1,2,3,4,5,6., the power of every group of luminous element has nothing in common with each other, and is respectively 60W, 40W and 25W.This luminaire and supporting lamp holder user mode circuit diagram are seen Fig. 2, and L1 lights when diverter switch 10 is connected 1,2 ends, and luminaire is 60W; L2 lights when diverter switch 10 is connected 3,4 ends, and luminaire is 40W; L3 lights when diverter switch 10 is connected 5,6 ends, and luminaire is 25W.Promptly this luminaire has dimming function.

If the power of above-mentioned three groups of luminous elements is identical,, can reach 3 times of common bulb its useful life though this moment, luminaire did not have dimming function.

Embodiment 2

Referring to Fig. 3, Fig. 4.The luminaire that this is routine, because three groups of luminous elements have a public exit 7, whole luminaire and matched lamp header structure are simpler.Diverter switch 10 adopts the single contact switch.L1 lights when diverter switch 10 is connected 1 end, and L2 lights when connecting 3 ends, and L3 lights when connecting 5 ends.

Supporting lamp holder of the present utility model also can be without diverter switch.Adopt the exit of contact position and luminous element 12 and bayonet socket position corresponding bayonet cap mutually, by the angle of change lamp holder and luminaire, the conversion luminous element is connected with contact, lights selected luminous element.Also can reach effect same as the previously described embodiments.

Adopt the beneficial effect of luminaire of the present utility model and supporting lamp holder to be: simple in structure, with low cost, the luminaire long service life, and have dimming function.
