Description
Technical field
The present invention relates to lighting field, more particularly to a kind of radiator structure of LED.
Background technology
The problem of how effectively being radiated on LED, all annoyings the technology people in industry always
Member.Existing LED generally comprises and LED light source component is provided with lampshade, lampshade, LED light source group
Part includes substrate and some LED lamp beads, and substrate is close to the top of lampshade inwall, and LED lamp bead is then solid
It is scheduled on substrate.When LED lamp bead is luminous, the heat produced by LED lamp bead is conducted to lampshade through substrate,
Again the radiating of LED lamp bead is realized through lampshade to external diffusion.But because the top of substrate and lampshade inwall is tight
Patch, during heat conducts, more closer to the heat for being close to place, i.e., temperature is higher, so as to lead
Cause the temperature around LED lamp bead higher, influence the service life of LED lamp bead.
The content of the invention
In order to overcome above-mentioned technical problem, it is an object of the invention to provide a kind of radiator structure of LED,
The radiator structure has more preferably radiating effect.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of radiator structure of LED, including lampshade, the lampshade have inner chamber, and the inner chamber is set
There is LED light source component, the LED light source component includes substrate and some LED lamp beads, the substrate
The inner chamber is fixed on, and the inner chamber is divided into the heat dissipation cavity on top and the reflection cavity of bottom, it is described
LED lamp bead is arranged on the substrate close to the side of the reflection cavity.
The venthole for the heat dissipation cavity to be in communication with the outside is offered on the lampshade.
The substrate clamping is fixed in the lampshade.
The substrate is aluminium base.
The beneficial effects of the present invention are：By substrate by the inner chamber of lampshade be divided into top heat dissipation cavity and
The reflection cavity of bottom, and LED lamp bead is arranged on substrate close to the side of reflection cavity, when LED lamp bead is luminous
When, the effect of the reflected cover of light can be projected outwardly, realize the illumination of LED；LED lamp bead is sent out
The heat gone out is conducted to heat dissipation cavity through substrate, and heat in heat dissipation cavity in spreading rapidly, and with heat dissipation cavity
Inwall is conducted to lampshade as conducting surface, in outwardly being spread on lampshade, heat is not excessively concentrated on
Around LED lamp bead, influence of the heat to LED lamp bead is significantly reduced, LED lamp bead is extended
Service life.Also, the inwall in above-mentioned structure setting, heat dissipation cavity in addition to substrate is conducting surface,
Make conducting surface that there is wider array of conduction surface, be rapidly transferred to lampshade beneficial to the heat in heat dissipation cavity, enter one
Walk the effect of heat radiation.

21 and some LED lamp beads 22, the substrate 2 is fixed on the inner chamber 11, and by the inner chamber 11
It is divided into the heat dissipation cavity 111 on top and the reflection cavity 112 of bottom, the LED lamp bead 22 is arranged on described
Substrate 2 is close to the side of the reflection cavity 112.
The inner chamber 11 of lampshade 1 is divided into heat dissipation cavity 111 and the reflection of bottom on top by substrate 21
Chamber 112, and LED lamp bead 22 is arranged on substrate 21 close to the side of reflection cavity 112, works as LED lamp bead
22 it is luminous when, the effect of the reflected cover 112 of light can be projected outwardly, realize the illumination of LED；
The heat that LED lamp bead 22 is sent is conducted to heat dissipation cavity 111 through substrate 21, and heat is in heat dissipation cavity 111
Interior rapid diffusion, and conducted using the inwall of heat dissipation cavity 111 as conducting surface to lampshade 1, on lampshade 1
Outwardly spread, heat is not excessively concentrated on around LED lamp bead 22, significantly reduce heat
Influence to LED lamp bead 22, extends the service life of LED lamp bead 22.Also, above-mentioned structure
Set, the inwall in heat dissipation cavity 111 in addition to substrate 21 is conducting surface, has conducting surface wider array of
Conduction surface, lampshade 1 is rapidly transferred to beneficial to the heat in heat dissipation cavity 111, further heat radiation
Effect.Wherein, the clamping of substrate 21 is fixed in the lampshade 1；And the substrate 21 is aluminium base
Plate, with more preferably radiating effect.
As the preferred embodiments of the present invention, being offered on the lampshade 1 is used for the heat dissipation cavity 111
