Description

Energy-saving lamp holder and lamp

The invention relates to the technical field of lighting fixtures, in particular to a split type energy-saving lamp holder and a lamp tube matched therewith. Background technique

The energy-saving lamps of the prior art generally adopt an integrated structure, and the circuit parts of the lamp tube and the energy-saving lamp as the light-emitting portion generally adopt an integrated structure, that is, each energy-saving lamp not only includes a lamp tube but also includes a circuit portion. Therefore, when the lamp is damaged and replaced, the energy-saving lamp not only replaces the lamp of the energy-saving lamp, but also replaces the circuit portion of the energy-saving lamp without damage. Since the life of the lamp of the energy-saving lamp is not very long and the replacement cycle is short, a large number of energy-saving lamp parts that are still usable are discarded every year, which not only has a terrible waste, but also a large amount of environmental pollution. . In addition, although the damage rate of the energy-saving lamp circuit portion is lower than that of the lamp tube, the accidental damage also requires the overall replacement of the energy-saving lamp, which wastes the intact energy-saving lamp tube. The Chinese patent document published on August 4, 2010 and published as CN101794703A discloses a split type energy-saving lamp, and an electrical connection point is added at the power receiving end of the lamp tube, and each electrical connection point is respectively connected with the filament in the lamp tube. Electrical connection of the lead wires; electrical connection points are also added in the lamp caps, and each electrical connection point is electrically connected to the output end of the circuit board in the lamp cap, and the position of the electrical connection point in the lamp cap corresponds to the electrical connection point on the lamp tube, The lamp tube is inserted into the lamp cap, and the corresponding contact between the respective connection points is realized, thereby realizing the power supply connection between the lamp tube and the lamp cap. This type of structure adopts the clamping method. When the time is long, the contact is prone to poor contact. In addition, the lamp tube lacks the corresponding heat dissipation device, and the heat generated by the lamp tube will seriously affect the normal operation of the circuit. jobs. A split type electronic energy-saving lamp comprising a lamp cap assembly and a lamp tube assembly is disclosed in the Chinese Patent Publication No. CN2919524, which is published on Jul. 4, 2007. The lamp cap assembly includes a lamp cap, a lamp holder and a card holder, and the lamp holder has a built-in base. There is an electronic rectifying plug-in board; the lamp tube assembly comprises a lamp tube and a lamp tube fixing seat; two flat-rotating arc card slots are arranged on the connecting end face of the lamp cap assembly, and two cylindrical head shapes are arranged on the connecting end face of the lamp tube assembly The lamp pin, the flat-rotating arc card slot is provided with an elastic contact piece for electrically connecting with the cylindrical head-shaped lamp pin, and at least two long arc-shaped card slots are arranged on the connecting end face of the lamp cap assembly, and the connecting end face of the lamp tube assembly The upper side is correspondingly provided with a T-shaped card pin matched with the long arc card slot, and the elastic contact piece is disposed on the electronic rectifying card board, and is in contact with the top end of the cylindrical head-shaped lamp pin to realize electrical connection. The split type energy-saving lamp of this structure is connected by the arc slot slot connection method, and the reliability of the contact part and the influence of the heat generated by the lamp tube on the circuit part are not solved, so the failure rate of the energy-saving lamp circuit is high, and the service life is high. Shorter. Disclosure of invention

The invention provides an energy-saving energy-saving lamp holder and a lamp tube for solving the problem that the integrated energy-saving lamp of the prior art wastes a large amount and seriously pollutes the environment.

The lamp post includes a spring seat and a spring and a spring sleeve disposed in the spring seat. The upper ends of the spring seat are respectively connected to the circuit board through wires. The energy-saving lamp with integrated structure is divided into two parts: a lamp holder and a lamp tube. The lamp holder is provided with a lamp socket cavity for arranging the energy-saving lamp circuit, and a lamp socket is arranged below the lamp socket cavity, and the lamp socket can be used for fastening the lamp In this way, when the lamp is badly damaged or damaged, we only need to replace the lamp, and the lamp holder can continue to be used. Similarly, when the circuit of the energy-saving lamp is damaged, we only need to replace the lamp holder, and the lamp can continue. It is used to effectively solve the waste and environmental pollution caused by the energy-saving lamp with integrated structure.

As a preferred structural form of the lamp holder, the upper end of the top cover of the energy-saving lamp lamp housing has a flat structure, and a power plug connector is arranged in the center, and the power plug connector is an external thread structure. The power plug connector here adopts a lamp cap structure of an ordinary incandescent lamp, preferably a screw connection structure or a plug structure, and the lamp socket of the energy-saving lamp can be directly connected to the lamp holder of the ordinary incandescent lamp.

As another structural form of the lamp holder, the upper end of the top cover on the energy-saving lamp lamp housing has a planar structure, and the center has a power inlet hole, and the edge of the planar structure is larger than the side wall of the lamp holder cavity to form an outward flange structure. The flanged structure is provided with a mounting hole. This is an energy-saving lamp holder structure that can be installed directly on the ceiling of a room. The purpose of the top cover is to facilitate the placement of the energy-saving lamp circuit in the socket cavity.
