Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp manufacturing technology, specifically relating to an explosion-proof reinforced structure for halogen lamps. Background Technology

[0002] Halogen lamps are high-efficiency incandescent lamps based on the halogen tungsten cycle principle. Their core structure includes a quartz glass shell, a tungsten filament, and halogen gas. When the filament is energized, it emits light at high temperatures. The evaporated tungsten combines with the halogen gas to form tungsten halide, which is then re-deposited on the filament surface through a cycle, thereby slowing down tungsten filament wear and improving luminous efficiency. Their compact size, high brightness, and color temperature stability make them widely used in automotive headlights, industrial lighting, and other fields.

[0003] The quartz glass shell of a halogen lamp is generally composed of a bulb and a bulb holder. The bulb is usually a cylindrical hollow structure, and the bulb holder is usually a flat and elongated square structure. The two are formed as a single piece in a molten state. The bulb and the bulb holder are connected by an arc-shaped transition. Because the stress is concentrated at the arc-shaped transition joint, when the vehicle is subjected to severe vibration or repeated thermal expansion and contraction, the arc-shaped transition joint is very prone to cracking, which not only affects the service life but also poses a safety hazard.

[0004] In view of the above, it is necessary to design an explosion-proof reinforced structure for halogen lamps that is simple in structure, easy to manufacture, and can effectively reduce the stress between the bulb and the bulb holder, thereby preventing breakage at the connection. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0005] The objective of this invention is to provide an explosion-proof reinforced structure for halogen lamps, which helps to improve the connection structure between the bulb and the bulb holder, thereby increasing the connection strength between the two and avoiding the problem of halogen lamps easily breaking under vibration and alternating hot and cold environments. This is beneficial to improving the service life and explosion-proof performance of halogen lamps.

[0006] The present invention achieves its objective as follows: An explosion-proof reinforced structure for a halogen lamp includes a bulb, a pair of molybdenum rods disposed within the bulb, and a filament disposed between the ends of the molybdenum rods and located within the bulb. A bulb holder is formed below the bulb, and a pair of molybdenum plates are disposed within the bulb holder. The lower ends of the molybdenum rods pass through the bulb holder and connect to the molybdenum plates. Each molybdenum plate is connected to a lamp foot extending out of the bulb holder. The invention is characterized in that: in a molten state, indentations are formed on the front and rear sides of the upper end of the bulb holder along the width direction; the material at the indentation locations is transferred into the bulb in a molten state; and the transferred material forms a pair of reinforcing ridges along the width direction on the inner side of the connection between the bulb and the bulb holder.

[0007] In a specific embodiment of this utility model, the bulb and bulb holder are made of quartz glass and are integrally formed in a molten state, with a pair of indentations and a pair of reinforcing protrusions also formed together.

[0008] In another specific embodiment of this utility model, a molybdenum rod support column is connected between the pair of molybdenum rods, and the molybdenum rod support column is located inside the bulb and near the middle of the molybdenum rods.

[0009] In another specific embodiment of this utility model, the light bulb has a cylindrical hollow structure, and the light bulb holder has a cuboid structure.

[0010] In another specific embodiment of this utility model, the molybdenum rod support column is made of quartz glass.

[0011] In another specific embodiment of this utility model, the lamp base is made of molybdenum rod material.

[0012] In a further specific embodiment of this utility model, the filament is a tungsten filament.

[0013] In a further specific embodiment of this utility model, the bulb is filled with a mixture of halogen gas and inert gas.

[0014] In yet another specific embodiment of this utility model, the halogen gas is one of iodine and bromine.

[0015] In yet another specific embodiment of this utility model, the inert gas is one of krypton, argon, and nitrogen.

[0016] The present invention has the following advantages due to the above-mentioned structure: the structure with indentations on the bulb holder and reinforcing ridges formed on the inner side of the connection between the bulb and the bulb holder effectively improves the connection strength between the two, avoids the problem of halogen lamps easily breaking under vibration and alternating hot and cold environments, and greatly improves the service life and explosion-proof performance of halogen lamps.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0020] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the concepts being described. Figure 1 The description of the location and state is intended to facilitate public understanding and should not be construed as a special limitation on the technical solution provided by this utility model.

[0021] Please see Figure 1 and combined Figure 2 This utility model relates to an explosion-proof reinforced structure for a halogen lamp, comprising a bulb 1, a pair of molybdenum rods 2 disposed within the bulb, and a filament 3 disposed between the ends of the molybdenum rods 2 and located within the bulb 1. A bulb holder 11 is formed below the bulb 1, and a pair of molybdenum sheets 5 are disposed within the bulb holder 11. The lower ends of the molybdenum rods 2 pass through the bulb holder 11 and connect to the molybdenum sheets 5. Each of the molybdenum sheets 5 has a lamp base 6 extending out of the bulb holder 11. The lamp base 6 is made of molybdenum rod material.

[0022] The technical innovation of this utility model is that: the front and rear sides of the upper end of the aforementioned bulb holder 11 are respectively pressed with an indentation 111 along the width direction in the molten state, and the material at the position of the aforementioned indentation 111 is transferred into the bulb 1 in the molten state. The transferred material forms a pair of reinforcing ridges 112 along the width direction on the inner side of the connection between the aforementioned bulb 1 and the bulb holder 11.

[0023] Furthermore, the aforementioned bulb 1 and bulb holder 11 are made of quartz glass and are integrally formed in a molten state, with a pair of indentations 111 and a pair of reinforcing protrusions 112 also formed together. The aforementioned bulb 1 has a cylindrical hollow structure, and the aforementioned bulb holder 11 has a cuboid structure. A molybdenum rod support column 4 connects the pair of aforementioned molybdenum rods 2, and the aforementioned molybdenum rod support column 4 is located inside the bulb 1 and near the center of the molybdenum rods 2. The aforementioned molybdenum rod support column 4 is made of quartz glass.

[0024] The aforementioned bulb 1 is filled with a mixture of halogen gas and inert gas. The halogen gas is one of iodine and bromine; in this embodiment, bromine is preferred. The inert gas is one of krypton, argon, and nitrogen; in this embodiment, nitrogen is preferred. The aforementioned filament 3 is a tungsten filament.

[0025] Please continue reading. Figure 1 and Figure 2During the integral forming process of the aforementioned bulb 1 and bulb holder 11, the material at the connection point is reduced due to the need for a curved surface transition, and stress is concentrated in the area with less material. In this technical solution, the aforementioned bulb holder 11 is a cuboid structure, and an indentation 111 is formed on its upper part. That is, the partial reduction of material does not affect the overall strength of the bulb holder 11. Then, the material on the bulb holder 11 is transferred to the bulb 1 through the aforementioned indentation 111 to the position at the connection between the bulb 1 and the bulb holder 11, forming the aforementioned reinforcing ridge 112. The reinforcing ridge 112 can reduce the stress at the connection between the bulb 1 and the bulb holder 11, thereby avoiding the problem of halogen lamps easily breaking under vibration and alternating hot and cold environments, and greatly improving the service life and explosion-proof performance of halogen lamps.

[0026] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
