Glue frame, multiple accommodating cavities 21 for being used to house LED are opened up on inside casing 2, each accommodating cavity 21 is arranged at intervals parallel and position
With the location matches of LED in spacing and lamp bar 1, the size of accommodating cavity 21 is more bigger than LED 11, between adjacent accommodating cavity 21
Form Great Wall position 212；Great Wall position 212 includes high Great Wall position 2121 and low Great Wall position 2122, high Great Wall position 2121 and low Great Wall position
2122 is arranged in a crossed manner, wherein arbitrary value, the height of low Great Wall position 2122 of the height of high Great Wall position 2121 between 0.9mm ~ 1.1mm
The arbitrary value spent between 0.4mm ~ 0.6mm, the height of high Great Wall position 2121 is arranged to 1mm, low Great Wall position in the present embodiment
2122 height is 0.5mm, so, low Great Wall position 2122 0.5mm lower than high Great Wall position 2121, so as to low Great Wall position 2122
Just it is above to have come out a space more.Lamp bar 1 is mutually bonded with inside casing 2 by heat-conducting glue 3, wherein in lamp bar 1 LED 11 it
Between position and inside casing on Great Wall position 212 be bonding location.
During work, the space on low Great Wall position 2122 is as heat abstractor, and LED distributes heat in itself when LED 11 lights
Amount, because the space on low Great Wall position 2122 is set, the heat that LED 11 distributes passes through thermal convection current heat transfer to interior low Great Wall
On position 2122 in the air in space, air transfers heat to inside casing 2 and is sent out mobile phone backlight eventually through the heat of inside casing 2 again to be dissipated
Outside heat structure.Due to the air receiver in space on low Great Wall position 2122 and the heat that LED 11 sends is cached, avoids LED
Itself being rapidly heated when lamp 11 is lighted causes longevity in life-span of LED 11 to influenceing even rapid failure.
Embodiment three
Accompanying drawing 5,6,7 and 8, a kind of mobile phone backlight cooling mechanism, including lamp bar 1 and inside casing 2 are referred to, the lamp bar 1 includes
FPCB plates and multiple LEDs 11, each LED 11 by two electrode weldings thereon corresponding to FPCB plates on pad, respectively
Individual LED can be realized by the circuit on FPCB plates to be connected with power supply and luminous.
In the present embodiment, inside casing 2 is the glue frame of plastic production, has been opened up on inside casing 2 multiple for housing the accommodating of LED
Chamber 21, each accommodating cavity 21 is arranged at intervals parallel and the location matches of position and spacing and LED in lamp bar 1, accommodating cavity 21
Size is more bigger than LED 11, and Great Wall position 212 is formed between adjacent accommodating cavity 21；The bottom of accommodating cavity 21 offers radiating groove
211, the depth of radiating groove 211 is between 0.1mm ~ 0.3mm, the depth 0.1mm of radiating groove 211, radiating groove 211 in the present embodiment
Length and the wide bottom than accommodating cavity 21 it is smaller；Great Wall position 212 includes high Great Wall position 2121 and low Great Wall position 2122, high Great Wall position
2121 and low Great Wall position 2122 it is arranged in a crossed manner, wherein arbitrary value of the height of high Great Wall position 2121 between 0.9mm ~ 1.1mm, low
Arbitrary value of the height of Great Wall position 2122 between 0.4mm ~ 0.6mm, the height of high Great Wall position 2121 is arranged in the present embodiment
1mm, the height of low Great Wall position 2122 is 0.5mm, so, low Great Wall position 2122 0.5mm lower than high Great Wall position 2121, so as to low
It is just above Great Wall position 2122 to have come out a space more.
Lamp bar 1 is mutually bonded with inside casing 2 by heat-conducting glue 3, wherein the position in lamp bar 1 between LED 11 and inside casing
On Great Wall position 212 be bonding location.
During work, the space on radiating groove 211 and low Great Wall position 2122 is as heat abstractor, LED when LED 11 lights
Itself distributes heat, and due to setting the space on radiating groove 211 and low Great Wall position 2122, the heat that LED 11 distributes passes through heat
Convection heat is delivered in the air in the space on radiating groove 211 and low Great Wall position 2122, and air transfers heat to interior again
Frame 2 is sent out outside mobile phone backlight radiator structure eventually through the heat of inside casing 2.Due on radiating groove 211 and low Great Wall position 2122
There is space, the air accommodated around LED is more, so as to preferably receive and cache the heat that LED 11 is sent, avoids
Itself being rapidly heated when LED 11 is lighted causes longevity in life-span of LED 11 to influenceing even rapid failure.
