Shockproof screw lamp holder and lamp provided with same

Abstract

The invention provides a shockproof screw lamp holder and a lamp provided with the same, conductive screw thread of the shockproof screw lamp holder is formed by bending a first elastic element, and a conductive contact in the shockproof screw lamp holder is arranged on a second elastic element which is axially arranged. The shockproof screw lamp holder adopts the first elastic element to make the conductive screw thread which is matched with a screw bulb and utilizes good elasticity of the first elastic element to achieve the damping effect, thus buffering the shock which is transmitted from the lamp holder to the bulb and avoiding the damage to the bulb owning to the shock; and simultaneously, as the conductive contact is arranged on the second elastic element which is axially arranged, the conductive contact is movably arranged, thus avoiding that a bulb contact is easy to separate from the conductive contact instantaneously in a shock environment when the conductive contact is rigidly fixed in the prior art, which causes the bulb to go out, and therefore, the screw lamp holder has good shockproof effect and can guarantee normal working of the lamp when being applied to the lamp.

Description

technical field [0001] The invention relates to the technical field of lighting, more specifically, to an anti-shock screw lamp holder and a lamp equipped with the anti-shock screw lamp holder. Background technique [0002] Lamps in the prior art, such as incandescent lamps, are generally composed of a lamp holder and a bulb, and the bulb is fixed on an external support surface through the lamp holder. The illuminant in the bulb is generally a tungsten wire, which is a thin wire formed by forging and drawing a tungsten rod. Due to the high hardness and brittleness of tungsten itself, when the tungsten wire passes through the current and reaches a certain temperature, it becomes more brittle after recrystallization, and it is easy to break under the condition of impact or vibration. [0003] When the external support surface vibrates, the light one will cause poor contact between the lamp holder and the bulb, causing the bulb to turn on and off, affecting the lighting; the s...

Problems solved by technology

[0003] When the external support surface vibrates, the light one will cause poor contact between the lamp holder and the bulb, causing the bulb to turn on and off, affecting the lighting; the severe one will transmit the vibration from the lamp holder to the bulb and cause the filament to break, causing the entire lamp to be damaged. damage
