APPLICATION NOTES
一．Heat dissipation
Because at present semiconductor light-emitting diode wafer technology restricting, LED
Photoelectricity change efficiency remains to be improved, especially high-power LED , is higher
because of it's power, have 60% the above electric energy to release to becoming a thermal energy (with
the development of semiconductor technology approximately, the photoelectricity conversion efficiency
meeting improves) gradually, be demanding a terminal when applying the high-power LED product the
customer right now, need to do a good job in heat dissipation, to ensure that the high-power LED product
works regularly.
My department submits suggestion about heat dissipation aspect according to product characteristic
property and long range aging test data experience, For your reference only.
1 The cooling fin demands.
Exterior and material quality: If the finished product seals off a request no highly, may aluminum product
or copper product cooling fin that convection , suggestion adopt to have fin movie happened directly with
the external world air environment.
2 Effective heat dissipation superficial areas:
I attend to 50-60 squares recommending the effective heat dissipation of cooling fin superficial
area sum ≥to 1 W high-power LED white light (colour is other basically identical) centimeter. 150 squares
recommending the effective heat dissipation of cooling fin superficial area sum ≥to 3 W products
centimeter, more, the high power looks at condition and test result increasing by ,
ensures that the cooling fin temperature does not exceed 60 to the full ~C
3 Connection methods:
The high-power LED base board and the cooling fin ensure that two contact surfaces neat , get in
touch with when linking up, please fine, for the union degree reinforcing two contact surfaces,
(3.0 W/m.k , heat conduction silicon greases suggesting that the base board bottom or the cooling
fin surface scribbles in LED applying a layer of heat conduction silicon grease heat conduction
silicon grease heat conduction modulus ≥) require that Tu applies homogeneously , closes just the
right amount again with screw pressure fixation.
二：Static electricity protects:
LED belongs to a semiconductor device , static electricity is face to face comparatively sensitive ,
especially with regard to white , green , blue, purple LED needs to do a good job in preventing static
electricity from coming into being and removing static electricity
1． Electrostatic creation:
①Friction: But part for again , be OK to produce static electricity after the object in the daily life, any
two being unlike material quality is contacted, produce electrostatic the most common method , be
the electricity rubbing a life. The material insulation is the better , the easier to rub the life electricity.
The object besides, being unlike matter any two kinds touches the queen parting for again , also can
