Abstract
The utility model relates to a signal lamp, which comprises a lamp cap and a glass housing, a core column and a filament are arranged in the glass housing, two guide wires are led out from the interior of the core column, the two ends of the filament are respectively connected with the two guide wires, a glass tube is arranged on the core column, and positioned between the two guide wires, a plurality of molybdenum wire hook groups are distributed in vertical direction of the glass tube, wherein the molybdenum wire hook group on a top layer comprises two molybdenum wire hooks which diagonally extend upwards, each molybdenum wire hook group on other layers comprises 2 molybdenum wire hooks positioned on an identical straight line, and the filament passes through the hook part of each molybdenum wire hook by one time along glass tube in a spiral encircling manner. The utility model adopts the technical proposal that the filament passes through each hook part by one time along glass tube in a spiral encircling manner, so that the stability of the filament is enhanced; and a light column with high lightness and high uniformity is formed, so that the visibility can be greatly improved.
Description
Technical field
The utility model relates to the signal lamp of a kind of luminous intensity height, uniformity height, good stability.
Background technology
Along with the development of World Economics, the application of signal lamp constantly increases, and the bulb that traditional signal lamp is furnished with different colours by ordinary lamps sends index signal, this class signal lamp ubiquity luminosity is low, the uniformity is not enough, poor stability, the shortcoming that the life-span is short; Therefore visibility is relatively poor, is not easy be it is found that, the accident that causes because of signal lamp constantly increases both at home and abroad, and the ship collision accident of especially colliding constantly increases, and has caused massive losses for people's life property.
Summary of the invention
The utility model provides a kind of luminous intensity height, uniformity height, stable high signal lamp at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of signal lamp, comprise lamp holder, glass bulb, be provided with stem stem, filament in the glass bulb, draw 2 seal wires in the described stem stem, the two ends of filament connect 2 seal wires, described stem stem is provided with glass-tube, glass-tube is located between 2 seal wires, on described glass-tube vertical direction, be distributed with several molybdenum wire hook groups, wherein the molybdenum wire hook group of top layer includes 2 molybdenum wire hooks that extend obliquely, each molybdenum wire hook group of all the other each layers all includes 2 molybdenum wire hooks that are on the same straight line, and filament once passes the hook portion of each molybdenum wire hook in the spiral surrounding mode along glass-tube.
As preferably, described molybdenum wire hook all is on the same plane.
As preferably, the number of described molybdenum wire hook group is 7.
For economical with materials, reduce cost, as preferably, described glass-tube is a hollow pipe.
According to the technical solution of the utility model, the hook portion that filament once passes each molybdenum wire hook along glass-tube in the spiral surrounding mode both can increase the stability of filament, had formed a luminosity height, light beam that the uniformity is high again, made visibility improve greatly.
Figure of description
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Embodiment: a kind of signal lamp, comprise lamp holder 1, glass bulb 2, be provided with stem stem 3, filament 4 in the glass bulb 2, draw 2 seal wires 5 in the described stem stem 2, the two ends of filament 4 connect 2 seal wires 5, and described stem stem 2 is provided with glass-tube 8, and glass-tube 8 is located between 2 seal wires 5.
On described glass-tube 8 vertical direction, be distributed with 7 molybdenum wire hook groups, wherein the molybdenum wire hook group of top layer includes 2 molybdenum wire hook 6s that extend obliquely, each molybdenum wire hook group of all the other each layers all includes 2 molybdenum wire hook 6b that are on the same straight line, and described molybdenum wire hook 6a, molybdenum wire hook 6b all are on the same plane.Filament 4 once passes the hook portion 7 of molybdenum wire hook 6a, molybdenum wire hook 6b in the spiral surrounding mode along glass-tube 8.
In order to save material, reduce cost, described glass-tube 8 is a hollow pipe.
