Abstract
The utility model technically aims to providing an LED bulb lamp with good heat-conducting structure, which has low cost, simple structure, extremely good heat dissipation effect and long service life. The LED bulb lamp comprises a lamp holder, wherein the lamp holder is connected with a plastic cement casing; an annular heat dissipation member is arranged in the plastic cement casing; the annular heat dissipation member is connected with a light source plate; the light source plate is provided with an LED light-emitting wafer and a PCB circuit; the PCB circuit is connected with a power supply; and the light source plate is provided with a lampshade. The LED bulb can dissipate heat emitted by the LED during work into the atmosphere, thereby regulating the normal working temperature and prolonging the service life of the LED bulb. The LED bulb is applicable to daily illumination.
Description
Technical field
The utility model relates to a kind of LED lamp, in particular, relates to a kind of LED bulb lamp with good heat conductive structure.
Background technology
Traditional bulb, it is luminous all to adopt the high drive tungsten filament, and both consumed power produced great amount of heat again.Unsatisfactory aspect energy-saving and emission-reduction.And the energy that LED emits surplus through carrier generation load causes photo emissions; Directly send the light of white or other colors; Can rational Application arrive the LED lighting, under the background of current global energy shortage, energy-conservation LED causes the sight that whole world people pay close attention to.The large-power LED light bead that currently marketed LED bulb lamp generally uses is used as light source, adopts metal shell to conduct the heat of lamp pearl.Exist short technological deficiency of heat conductivility difference and service life, the technological deficiency that the LED bulb lamp exists in the prior art, those skilled in the art's technical problem anxious to be solved now.
Summary of the invention
The technical purpose of the utility model is to overcome in the prior art, and the LED bulb lamp exists the technical problem of heat dispersion difference, provides a kind of with low cost, and is simple in structure and radiating effect is splendid, the LED bulb lamp with good heat conductive structure of long service life.
For realizing above technical purpose, the technical scheme of the utility model is
LED bulb lamp with good heat conductive structure; Include lamp holder, said lamp holder is connected with plastic shell, is provided with annular radiating piece in the said plastic shell; Be connected with light source board on the said annular radiating piece; Light source board is provided with LED luminescent wafer and PCB circuit, and said PCB circuit connects power supply, and said light source board is provided with lampshade.
Further, said plastic shell is provided with diathermanous hole.
Further, said annular radiating piece is provided with fin.
In the application of the utility model; Be provided with power circuit in lamp holder and the plastic casing,, be provided with annular radiating piece in the plastic casing for PCB circuit on the light source board and the power supply of LED luminescent wafer; The annular radiating piece directly contacts with light source board; The heat that the LED luminescent wafer is sent in time dispels the heat through annular radiating piece, through the diathermanous hole on the plastic shell, is dispersed in the atmosphere again; The annular radiating piece adopts the metal crimp foundry goods to make.
The useful technique effect of the utility model is: through above-mentioned structure, the heat that the utility model can be splendid is sent when LED is worked is dispersed in the atmosphere, has regulated the normal working temperature of LED, has prolonged the working life of LED bulb lamp.
