Abstract

The invention discloses a light-emitting diode (LED) lamp with a screw base. The LED lamp comprises a lens, an LED aluminum base plate, a heat radiating body, a plastic base, a driving power supply and a lamp base, wherein the neck part of the heat radiating body is provided with an integrated heat-conducting plate; the lens and the LED aluminum base plate are arranged in a cup-shaped cavity of the heat radiating body and are fixed by a check ring; the bottom of the heat radiating body is connected with the plastic base to form a sealed cavity; the driving power supply is arranged in the sealed cavity; the bottom of the plastic base is connected with the lamp base and is provided with a bayonet; and a wiring groove is formed under the bayonet. Compared with the prior art, the invention has the advantages that: the LED lamp with the screw base can obviously reduce poor contact in the LED lamp, effectively prevent that an LED is off-center and crushed by a lens cup cover adherend after heat radiating adhesive is coated on the LED aluminum base plate, and effectively avoid that positive and negative leads are wound and power leads are broken when the plastic base is rotatably matched with the heat radiating body; and as the base is made from poly butylenes terephthalate (PBT) plastic, the plastic base of the LED lamp is difficult to burn out.

Description

Band screw socket LED lamp

Technical field

The invention belongs to the LED technical field, especially relate to a kind of band screw socket LED lamp.

Background technology

Continuous development and maturation along with the LED technology; The performance indications of LED increase substantially day by day; Make LED obtain using widely at lighting field; LED compare with the energy-saving lighting lamp of general photo-voltaic power supply adapted have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage, people it be described as 21 century replace fluorescent lamps and incandescent lamp the 4th generation lighting source.

Existing LED light fixture is of a great variety, but the service life of LED light fixture is generally shorter, mainly contains several reasons and causes; At first be exactly that the LED lamp is under long-time user mode; The energy that it produced can not in time be discharged, and makes the burning out of plastic feet of LED lamp to cause the inner loose contact of LED lamp; Secondly it is disconnected that power lead positive negative conductor when plastic feet cooperates with the radiator rotation twines strand easily; Moreover be exactly that the LED aluminium base is stamped after the thermal paste LED off-centre and passed through the mirror cup cover adherend easily and crush; But not relevant at present prior art solves these problems, therefore is necessary to improve.

Summary of the invention

The objective of the invention is provides a kind of obvious minimizing the band screw socket LED lamp of the inner contact of LED lamp condition of poor to occur for the deficiency that solves above-mentioned prior art.

To achieve these goals, the band screw socket LED lamp that the present invention designed comprises lens, reflector, LED aluminium base, radiator, plastic feet, driving power and lamp holder; The radiator neck is provided with the heat-conducting plate of integral type; Lens, reflector and LED aluminium base are located in the cup die cavity of radiator and fix through back-up ring, and the bottom and the plastic feet of radiator are connected to form cavity, and driving power is located in the cavity; The bottom of plastic feet is connected with lamp holder; The bottom of said plastic feet is provided with bayonet socket, is provided with the unwrapping wire groove below the bayonet socket, and the unwrapping wire groove can realize that lead contacts with the multiple spot of lamp holder; Contact is all arranged inside and outside the lamp holder, and obviously the inner contact of LED lamp condition of poor appears in minimizing.

In order to prevent effectively that the LED aluminium base from stamping after the thermal paste that LED is eccentric to be passed through the mirror cup cover adherend and crush, said heat-conducting plate is provided with locating slot, and the LED aluminium base is located on the locating slot.

Break in order effectively to avoid power lead positive negative conductor when plastic feet cooperates with the radiator rotation to twine strand, said heat-conducting plate and radiator inwall junction are provided with the screw thread eccentric orfice.

For the plastic feet that makes LED lamp easy burn-out not, said plastic feet material is the PBT plastics.

The band screw socket LED lamp that the present invention obtains is compared the advantage that is had with prior art and is: the present invention can obviously reduce and occurs that the LED lamp is inner to contact condition of poor, and the bottom of plastic feet is provided with bayonet socket, is provided with the unwrapping wire groove below the bayonet socket; The locating slot that heat-conducting plate is provided with, LED aluminium base are located at and can prevent effectively on the locating slot that the LED aluminium base from stamping after the thermal paste that LED is eccentric to be passed through the mirror cup cover adherend and crush; Heat-conducting plate is provided with the screw thread eccentric orfice with radiator inwall junction and can effectively avoids power lead positive negative conductor winding strand when plastic feet cooperates with the radiator rotation disconnected; Submount material is the PBT plastics, and the plastic feet that makes the LED lamp is easy burn-out not.
