Description
Technical field
The present invention relates to lighting field, more particularly to a kind of LED of service life length.
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 LED of service life length,
The LED has more preferably radiating effect.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of LED of service life length, including lampshade, the lampshade have inner chamber, and the inner chamber is set
LED light source component is equipped with, the LED light source component includes substrate and some LED lamp beads, the base
Plate is fixed on the inner chamber, and the inner chamber is divided into the heat dissipation cavity on top and the reflection cavity of bottom, institute
Stating LED lamp bead and being arranged on the substrate and offered on the side of the reflection cavity, the substrate is used for
The intercommunicating pore of the heat dissipation cavity and the reflection cavity is connected, the reflection cavity has light-emitting window, the light extraction
It is provided with mouthful on light-passing board, the light-passing board and offers air admission hole, is offered on the lampshade for inciting somebody to action
The venthole that the heat dissipation cavity is in communication with the outside.
Dust-proof air ventilation net is provided with the air admission hole and the venthole.
The substrate clamping is fixed in the lampshade.
The light-passing board is sealingly disposed in the light-emitting window.
The substrate is aluminium base.
The beneficial effects of the present invention are：1st, by substrate by the inner chamber of lampshade be divided into the heat dissipation cavity on top with
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 hair
Light time, light is outwardly projected by the reflex of reflector through the light-passing board at light-emitting window, is realized
The illumination of LED；The heat that LED lamp bead is sent is conducted to heat dissipation cavity through substrate, and heat is in heat dissipation cavity
Rapid diffusion, and being conducted using the inwall of heat dissipation cavity as conducting surface to lampshade, in outwardly being spread on lampshade,
Heat excessively will not be concentrated on around LED lamp bead, significantly reduce shadow of the heat to LED lamp bead
Ring, extend the service life of LED lamp bead.Also, substrate is removed in above-mentioned structure setting, heat dissipation cavity
Inwall in addition is conducting surface, conducting surface is had wider array of conduction surface, beneficial to the heat in heat dissipation cavity
Amount is rapidly transferred to lampshade, the effect of further heat radiation.2nd, by above-mentioned structure setting, successively
The heat dissipation channel of LED is made up of air admission hole, reflection cavity, intercommunicating pore, heat dissipation cavity and venthole；When
When LED is illuminated, extraneous cold air is flowed into heat dissipation channel from air admission hole, and the heat in heat dissipation channel is empty
Gas from venthole outflow, forms the convection current of air, the heat in LED is followed pair of air
The extraneous diffusion of flow direction；Also, the air of convection current can be by the lower section (reflection cavity) of substrate, through substrate
(intercommunicating pore) and the top (heat dissipation cavity) by substrate, realizes the comprehensive radiating inside and outside substrate,
Effective substrate cooling system is formed, promptly the heat on substrate is taken away, LED is had more preferably
Radiating effect.3rd, when air admission hole and intercommunicating pore longitudinally stagger certain position, the sky flowed into from air admission hole
Gas can be stopped by substrate, and in being flowed in reflection cavity, effectively enhance air in reflection cavity
Mobility, it is ensured that air can take away heat.Similarly, when intercommunicating pore and venthole longitudinally stagger necessarily
During position, it can be stopped from intercommunicating pore leaked-in air by lampshade, and in being flowed in heat dissipation cavity, effectively
Ground enhances air in the mobility in heat dissipation cavity, it is ensured that air can take away heat.
Brief description of the drawings
Fig. 1 is the schematic diagram of the LED of the present invention.
Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further：
Reference picture 1, a kind of LED of service life length, including lampshade 1, the lampshade 1 have inner chamber
11, the inner chamber 11 is provided with LED light source component 2, and the LED light source component 2 includes substrate 21
And some LED lamp beads 22, the substrate 21 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 21 is offered on the side of the reflection cavity 112, the substrate 21 for connecting described dissipate
The intercommunicating pore 23 of hot chamber 111 and the reflection cavity 112, the reflection cavity 112 has light-emitting window 113,
It is provided with the light-emitting window 113 on light-passing board 3, the light-passing board 3 and offers air admission hole 31, it is described
The venthole 12 for the heat dissipation cavity 111 to be in communication with the outside is offered on lampshade 1.
The 1st, the inner chamber of lampshade is divided into the heat dissipation cavity on top and the reflection cavity of bottom, and LED by substrate
Lamp bead is arranged on substrate close to the side of reflection cavity, and when LED lamp bead is luminous, light passes through reflector
Reflex, is outwardly projected through the light-passing board at light-emitting window, realizes the illumination of LED；LED lamp bead
The heat sent is conducted to heat dissipation cavity through substrate, and heat in heat dissipation cavity in spreading rapidly, and with heat dissipation cavity
Inwall conducted as conducting surface to lampshade, in outwardly being spread on lampshade, heat is not excessively concentrated
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 conduction
Face, makes conducting surface have wider array of conduction surface, and lampshade is rapidly transferred to beneficial to the heat in heat dissipation cavity,
The effect of further heat radiation.
2nd, by above-mentioned structure setting, successively by air admission hole, reflection cavity, intercommunicating pore, heat dissipation cavity and
