Abstract
The utility model relates to an electro-optic conversion device, in particular to a novel soft start lamp bulb suitable for a railway signal. The lamp bulb consists of a lamp cap, a lamp housing, lamp filaments, a lamp filament combined supporting rack, and an adjusting cover. A soft starting device is connected in a lamp filament circuit in series, each lamp filament adopts a double spiral cylindrical shape, the main lamp filament and the auxiliary lamp filament are in the shape of a straight line and are mutually parallel, and the adjusting cover is a cylindrical whole shape formed by being pressed once. Compared with the prior art, the utility model has the advantages that the illuminant lightness is increased, the added signal displays the distance, the service life of the lamp bulb is improved, the replacement frequency of the lamp bulb is reduced, and the maintenance work load is reduced.
Description
The utility model relates to electro-optical conversioning device, particularly a kind of incandescent lamp bulb of using of railway signal lamp.
The present incandescent lamp bulb that uses, the bulb used of railway signal particularly, adopt the ordinary incandescent lamp bubble mostly, luminous efficiency is lower, owing to circuit debugging, turn-off more frequently, impulse current reaches tens of times of stationary value in the use, and the filament of bulb is fragile, directly affect the useful life of signal lamp, disturb normal transport.
Goal of the invention of the present utility model is to overcome the shortcoming and defect that prior art exists, and designs a kind of novel soft start bulb, requires both durable, prolongation bulb life, the brightness in the time of increasing bulb again and light.
Goal of the invention of the present utility model can be achieved through the following technical solutions: the soft start bulb partly is made of lamp holder, lamp housing, filament sectional shelf-unit, the adjustment nest of tables.Soft-start device of series connection in the circuit of bulb, filament adopts double helix garden cylindricality, the main linearly new arrangement architecture of shape and the in-line that is parallel to each other of filament of paying.
The utility model compared with the prior art, improved brightness of illumination greatly, strengthened signal display distance, because the soft-start device of series connection negative tempperature coefficient thermistor in heater chain, can limit the surge current when starting, the useful life of having improved bulb, the replacing number of times of minimizing bulb, reduce maintenance workload, help getting rid of interference driving.
Below in conjunction with accompanying drawing and most preferred embodiment the utility model is done description in further detail.
Accompanying drawing one is a soft start bulb overall structure schematic diagram.
Accompanying drawing two is adjusted the nested structure schematic diagram for the soft start bulb.
Among the figure, 1 is lamp holder, and 2 is soft-start device, and 3 for adjusting cover, and 4 is the filament sectional shelf-unit, and 5 is lamp housing, and 6 is the main filament contact, and 7 are the main filament lead-in wire.
Most preferred embodiment:
The soft start bulb is by lamp holder 1, lamp housing 5, and filament sectional shelf-unit 4 is adjusted cover more than 3 parts and constituted.Soft-start device 2 of series connection in the circuit of bulb, soft-start device 2 is to be made by negative temperature coefficient heat-sensitive resistance material, the surge current when starting in order to restriction.Connect moment at circuit power; exceed more than ten times surge current in the time of can producing than operate as normal in the circuit; and the initial resistance of negative tempperature coefficient thermistor is bigger; can suppress electric current excessive in the circuit is difficult for blowing with the protection filament; when circuit enters normal operating conditions; thermistor is owing to cause that by electric current the resistance body temperature rises, and resistance drops to very little, can not influence the operate as normal of circuit.Soft-start device can be connected with main filament, and one terminates on the main filament contact 6 of lamp holder 1, and the other end is connected on the main filament connecting line 7.
Filament adopts double helix garden column construction, the main linearly new arrangement architecture of shape and the in-line that is parallel to each other of filament of paying.
Above lamp holder 1, be provided with and adjust cover 3, in order to anchored filament sectional shelf-unit 4, lamp housing 5, the distance of fixing simultaneously and adjustment and lamp holder 1, the assurance filament is exactly on focus, and the light that bulb is sent reaches maximum range.Adjust the cover 3 garden post shapes that form for disposable compacting.Be connected between lamp holder 1 and lamp housing 5, thereby reach stably anchored filament sectional shelf-unit 4 and lamp housing 5, realize the distance of fixing reliably and adjustment and lamp holder 1.
Be filled with elements such as krypton, halogen, nitrogen in the lamp housing 5,, and make filament be difficult for evaporation, prolong the useful life of bulb with the luminous brightness of increase bulb.
Claims (2)
1. soft start bulb, form by lamp holder, lamp housing, filament, filament sectional shelf-unit, adjustment cover, it is characterized in that series connection one soft-start device (2) in the heater chain, filament (5) adopts double helix garden cylindricality, the main linearly shape and being parallel to each other of filament of paying is adjusted the whole shape of garden post that cover (3) forms for compacting once.
2. according to the described soft start bulb of claim, it is characterized in that soft-start device (2) is to be made by negative tempperature coefficient thermistor.
