Abstract

The utility model discloses a clamping light-emitting diode (LED) lamp, which comprises lamp beads and a lamp holder, wherein each lamp bead comprises a lamp bead bulb, an annular insulating plastic and an electrode plate; the lamp holder comprises a lamp cap, a lamp holder inner plate and a radiating shell; two sides of the annular insulating plastic are provided with arc steps; conductive plates are fixed on the arc steps; an epoxy resin insulating plate is arranged on the surface of the lamp holder inner plate; a circular clamping groove for mounting lamp beads is formed on the epoxy resin insulating plate; and a conductive compressed leaf spring which is butted with the conductive plate in a sliding mode is arranged on the inner surface of the clamping groove. According to the clamping LED lamp provided in the utility model, the connection mode of the traditional LED lamp is completely changed, the lamp beads are detachably separated from the power supply, the lamp beads can be directly detached and replaced, and the using cost of the LED lamp is greatly reduced; an aluminum substrate is optimized and emitted, the radiation is direct, and the radiating effect is good, so that the service life of the LED lamp is relatively prolonged; and moreover, the aluminum substrate is not used, and the production cost of the LED lamp is greatly reduced.

Description

A kind of plug-in LED lamp

Technical field

The utility model relates to a kind of plug-in LED lamp.

Background technology

Present existing LED illuminating lamp on the domestic and international market, its lamp pearl, power supply are holistic structure to lamp housing, because the lamp pearl of existing LED lamp all is employings lamp pearl positive and negative extremely are welded on the front of aluminium base; Aluminium base source of welding current lead; The reverse side of aluminium base coagulates slurry as silicone oil etc. through coated with thermally conductive and contacts with the lamp socket inner panel when the LED lamp is installed, this complex manufacturing technology, and as damaging then because of light emitting diode (LED) or a small components integral LED lamp promptly can not use; All scrap; And the cost of aluminium base accounts for sizable ratio in the whole LED lamp, thereby has caused the significant wastage of material, causes the price of LED lamp high all the time; Simultaneously; Because the efficient of LED lamp receives temperatures involved easily and sharply descend, more also to produce heat after the waste electric power, make temperature further rise; Form vicious circle easily; Also can shorten life-span of LED the electric power except that waste, therefore good heat radiation also has great motive force for applying of LED lamp, and existing LED lamp pearl adopts aluminium base to coagulate effect that slurry dispels the heat and not ideal enough as electric substrate and through the heat conduction that applies.

Summary of the invention

The purpose of the utility model promptly provide a kind of simple in structure, the lamp pearl can change, cost of manufacture is low, the plug-in LED lamp of perfect heat-dissipating.

The LED lamp of the utility model; Comprise LED lamp pearl and the lamp socket that is used for fixing the lamp pearl; Said lamp pearl comprises lamp bulb, is used for protecting the annular ambroin of lamp bulb and the electrode slice that is used to connect power supply of drawing from ambroin, and the bottom of said lamp bulb is provided with the base fin, and said lamp socket comprises lamp holder, lamp socket inner panel and heat-dissipating casing; Said annular ambroin both sides are provided with the arc step, are fixed with the conductive plate that is connected with electrode slice on the said arc step; Said lamp socket inner panel surface is provided with the epoxy resins insulation plate, and said epoxy resins insulation plate is provided with the circular draw-in groove that is used to install the lamp pearl, and said draw-in groove inner surface is provided with the conduction making leaf spring that slides mutually and dock with conductive plate, and said making leaf spring connects power lead.

Said base fin abuts on the lamp socket inner panel.

The beneficial effect of the utility model is:

1, changed the connected mode of traditional LED lamp fully; Change into LED illumination one split type; The lamp pearl detachably separates with power supply, has gone bad like the lamp pearl in daily life, directly pulls down more to renew the lamp pearl and get final product; And original lamp housing still can continue to use, and greatly reduces the use cost of LED lamp;

2, aluminium base has been omitted in optimization; The lamp pearl of the LED lamp of the utility model partly directly is connected with metal lamp holder inner panel and lamp heat-dissipating casing through the base fin; Make heat radiation more direct; Radiating effect is better, thereby has also prolonged the service life of LED lamp relatively, and does not use aluminium base also to greatly reduce the production cost of LED lamp.

The specific embodiment

Shown in Fig. 1-5; The LED lamp of the utility model; Comprise LED lamp pearl and the lamp socket that is used for fixing the lamp pearl; Wherein the lamp pearl comprises lamp bulb 1, is used for protecting the annular ambroin 2 of lamp bulb and from the electrode slice that is used to connect power supply that ambroin is drawn, is provided with base fin 4 in the bottom of lamp bulb 1, and the base fin abuts on the lamp socket inner panel 7; The lamp socket of this LED lamp comprises lamp holder 11, lamp socket inner panel 7 and heat-dissipating casing 10, and the both sides of annular ambroin 2 are provided with arc step 9, is fixed with the conductive plate 8 that is connected with electrode slice on this arc step; On lamp socket inner panel 7 surfaces, be provided with epoxy resins insulation plate 6, the epoxy resins insulation plate is provided with the circular draw-in groove 3 that is used to install the lamp pearl, and this draw-in groove inner surface is provided with the conduction making leaf spring 5 that slides mutually and dock with conductive plate 8, and this making leaf spring connects power lead.The utility model in use; Only need the lamp pearl is inserted circular draw-in groove and rotation can be connected to arc step 9 in the draw-in groove 3, at this moment, the conductive plate 8 on the arc step 9 promptly with draw-in groove in making leaf spring 5 be electrically connected; This moment, the LED lamp can normally use; In the time of need changing like the lamp pearl, only need to make it screw out draw-in groove the rotation of lamp pearl and can take out former lamp pearl, more renew the lamp pearl and get final product.The utility model has changed the connected mode of traditional LED lamp fully; Change into LED illumination one split type; The lamp pearl detachably separates with power supply, has gone bad like the lamp pearl in daily life, directly pulls down more to renew the lamp pearl and get final product; And original lamp housing still can continue to use, and greatly reduces the use cost of LED lamp; Aluminium base has been omitted in the utility model optimization; The lamp pearl of the LED lamp of the utility model partly directly is connected with metal lamp holder inner panel and lamp heat-dissipating casing through the base fin; Make heat radiation more direct; Radiating effect is better, thereby has also prolonged the service life of LED lamp relatively, and does not use aluminium base also to greatly reduce the production cost of LED lamp.
