Abstract
The utility model discloses an LED lamp, comprising a metal lampshade. The utility model adopts the technical scheme that the lampshade is internally provided with a heat conductive plate that can transfer the heat to the lampshade, an Al-substrate circuit board is tightly stuck on the heat conductive plate, an LED bulb is arranged on the Al-substrate circuit board, and a conical lamp cup is arranged at the outer side of the LED bulb. The purpose of the utility model is to overcome the defects of the prior art and provide a durable LED lamp in which the circuit board is tightly stuck with the lampshade to transfer and radiate heat.
Description
[technical field]
The utility model relates to a kind of LED lamp.
[background technology]
LED is extensive use of, come into huge numbers of families, however the heat dissipation problem of LED lamp be not well solved all the time, existing LED Lamp cup all is a conical surface housing, can not heat conduction, be unfavorable for heat radiation, directly contacting, conduct heat between existing lampshade and circuit board and the LED bulb by air, radiating effect is poor, LED bulb and circuit board heat up easily, cause the LED lamp life-span to shorten, and can not durablely use.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art, provides a kind of circuit board and lampshade to be close to direct heat transfer heat radiation, the LED lamp of durable use.
The utility model is achieved through the following technical solutions:
A kind of LED lamp, comprise metal housing, it is characterized in that being provided with in the described outer cover and can conduct heat to the heat-conducting plate that dispels the heat on the outer cover, be glued with aluminium base circuit board on the described heat-conducting plate, described aluminium base circuit board is provided with the LED bulb, and the described LED bulb outside is provided with the taper Lamp cup.
Aforesaid LED lamp is characterized in that described taper Lamp cup is that the upper end is provided with solid light penetrating object, and the top of taper Lamp cup is provided with bulb hole, and described LED bulb stretches in the bulb hole.
Aforesaid LED lamp is characterized in that described outer cover comprises cover and following cover.
Aforesaid LED lamp is characterized in that the described outer cover outside is provided with fin.
Aforesaid LED lamp is characterized in that described outer cover cover mouth place is provided with the collar of holding the taper Lamp cup.
Aforesaid LED lamp is characterized in that described upward cover and forms between the cover down being provided with battery cavities, in the described battery cavities battery is housed.
Compared with prior art, the utility model has following advantage:
The utility model lampshade is provided with heat-conducting plate, the direct and heat-conducting plate applying conduction heat transfer of aluminium base, and good heat dissipation effect, solid taper printing opacity Lamp cup contacts with aluminium base and helps heat radiation, more helps guaranteeing better heat radiating effect.
