Abstract

The utility model discloses an LED lamp which comprises a lamp bead and a lamp holder. The lamp bead comprises a lamp bead bubble, insulating plastics and anode and cathode fixing pins, wherein screw holes are arranged on the anode and cathode fixing pins, a nut is arranged on a lamp holder inner plate, an insulating layer is arranged between the nut and the lamp holder, the lower end of the nut is connected with a power guide line, and the anode and cathode fixing pins are connected to the lamp holder inner plate through nuts and screws. According to the LED lamp, a traditional LED lamp connection mode is changed completely, the lamp bead and a power source can be detachably separated; and if the lamp bead is broken in daily life, only the lamp bead is detached to be changed, an original lamp casing can be used continuously, and the usage cost of the LED lamp is reduced greatly. The LED lamp has the advantages that an aluminum substrate is optimized and omitted, the cooling is direct, the cooling effect is good, the service life of the LED lamp is relatively prolonged, and the production cost of the LED lamp is reduced greatly as the aluminum substrate is not used.

Description

A kind of LED lamp

Technical field

The utility model relates to a kind of 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 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 to protect the ambroin and the positive and negative electrode fixing feet that is used to be connected power supply of lamp bulb, and the bottom of said lamp bulb is provided with the base fin, and said lamp socket comprises lamp holder, heat-dissipating casing and lamp socket inner panel; It is characterized in that: said positive and negative electrode fixing feet is provided with screw hole; Said lamp socket inner panel is provided with nut, is provided with insulating barrier between nut and the lamp socket inner panel, and the lower end of said nut connects power lead; Said positive and negative electrode fixing feet is connected on the lamp socket inner panel through nut and screw.

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.
