Description

A single-ended tungsten-halogen lamp mounting structure

The utility model relates to the technical field of tungsten-halogen lamps, in particular to a single-end tungsten-halogen lamp mounting structure.

The existing 220V single-ended tungsten-halogen lamp adopts two structures, one is "M" type structure, as shown in Figure 1 and Figure 2, it adopts a threaded tail structure, the filament 1 is divided into five sections, glass beads There are two electrode molybdenum wires 3 and four supporting molybdenum wires 2 on the 4, and the four supporting molybdenum wires 2 and the two electrode molybdenum wires 3 are symmetrically located on both sides of the X-axis of the glass bead. The supporting molybdenum wire 2 needs to be selected with a larger diameter, and its structure is complicated, so it can only be operated manually, and mechanized production cannot be realized. When the lamp is ignited vertically downward, the slight drooping of the filament is easy to cause accumulation and lead to short life. One is a concentrating single-ended halogen tungsten bulb, as shown in Figure 3 and Figure 4, which is composed of a bulb 5, a filament 6, a glass bead 7, a molybdenum foil 8, and a molybdenum foot 9, and the filament is perpendicular to the axis of the glass bulb. On the plane, because its structure limits the length of the filament, it is difficult to shape the filament, and because the tops of several supporting molybdenum wires are on the same plane, the distance between the molybdenum wires is small, and it is difficult to realize mechanized production.

The purpose of the utility model is to provide a new single-end halogen tungsten lamp mounting structure with long service life and easy mechanized operation.

The purpose of this utility model is achieved in this way: a single-ended tungsten-halogen lamp mounting structure, including a glass bead, two electrode molybdenum wires passing through the glass bead, a filament and its supporting molybdenum wire, two molybdenum wires inlaid on the glass bead One support molybdenum wire and two electrode molybdenum wires are insulated from each other, one end of the filament is clamped at the top of one electrode molybdenum wire, and then passed through the top of the two support molybdenum wires and fixed on the top of the other electrode molybdenum wire, the filament is in a three-section structure The two electrode molybdenum wires and the two supporting molybdenum wires are oblique to both sides of the glass bead X-axis respectively, and the included angles α ₁ and α ₂ between the electrode molybdenum wire and the glass bead X-axis are both 0°～160°, and the supporting The included angles β ₁ and β ₂ between the molybdenum wire and the X-axis of the glass bead are both 0°～60°; the height difference between the highest point of the electrode molybdenum wire and the highest point of the support molybdenum wire in the X-axis is not less than 1.5mm. In order to facilitate the forming of the hook when the machine is stretched, a supporting molybdenum wire with a smaller diameter is selected, generally φ0.10～φ0.35mm. In order to suppress flashing and tripping in the lamp, the two electrode molybdenum wires are respectively located outside the two supporting molybdenum wires, so that the distance between the poles of the lamp reaches the maximum value in the bulb.

The utility model has the advantages of:

(1) When the lamp is ignited vertically downward, the filament will not be short-lived due to accumulation and short circuit caused by slight drooping.

(2) This kind of stretching structure makes the distance between the two electrodes reach the maximum value in the bulb, which effectively suppresses the instantaneous flashing and tripping of the lamp, and also greatly reduces the probability of frying the lamp.

(3) The structure is simple, and the distance between the molybdenum wires is large, which is convenient for machine stretching, saves labor and reduces costs. Due to the compact and reasonable structure, it is short and delicate after being made into a light bulb, and can be put into a cold reflector cup.

Referring to Fig. 5-Fig. 7, the single-ended tungsten-halogen lamp mounting structure of one embodiment of the present invention consists of glass beads 10, two supporting molybdenum wires 12, 13 with a diameter of φ0.16mm, and two electrode molybdenum wires 11 , 14 and filament 16 are formed. Machine tensioning can be used: the ends of the electrode molybdenum wires 11 and 14 on the glass beads 10 are flattened by mechanical stamping, and then one half of the flattened part is bent at an angle of 180°, and one end of the filament 16 is clamped on the flattened On the end of the electrode molybdenum wire 11, bend the ends of two supporting molybdenum wires 12, 13 into a closed circle, and the filament 16 passes through the circle of supporting molybdenum wires 12, 13, and finally the tail of the filament 16 is clamped in the flattened Another electrode molybdenum wire 14 upper end of bending. Manual stretching can also be used, that is, the conventional way of threading the filament tail is adopted at the filament tail.

The two electrode molybdenum wires 11, 14 and the two supporting molybdenum wires 12, 13 are respectively oblique to the two sides of the X-axis of the glass bead. As can be seen from Figure 5, the distance between the ends of two supporting molybdenum wires 12 and 13 is A, the distance between the ends of one supporting molybdenum wire 11 and the end of the same side electrode molybdenum wire 13 is B, and the values of A and B can be determined according to the length of the filament and the glass.
