Description
Technical field
The present invention relates to the LED lighting field, particularly relate to a kind of LED driving power.
Background technology
The outdoor driving power of existing LED is for accomplishing more than the IP65; All adopt the mode of embedding, the embedding filler mainly contains the filling of epoxy resin solid or the silica gel software is filled, and can produce heat energy during owing to power work; Cause the inner components and parts of power supply to produce thermal expansion; Because each device coefficient of expansion is different, device can produce mutual extrusion when expanding, thereby influences the reliability of power supply; Because solid or software filler heat conductivility are all bad, cause the heat of power supply apparatus effectively not distribute, thereby the life-span that influences device are the life-span of power supply; Because solid or software filler are bad because of its flowability when embedding, when embedding, produce the space easily, thereby influence water resistance, and be difficult to repair after the embedding inefficacy.
Summary of the invention
First technical problem to be solved by this invention is: provide a kind of with waterproof and the heat dissipating method of liquid as filler; When this method has solved power work effectively; The heat that device produces is effectively taken to outside the power source body, has reduced the temperature rise of power supply, has prolonged power source life; Avoided because thermal expansion to the extruding that components and parts produce, has improved the reliability of power supply; Help power supply embedding operation, when power-fail, be easy to reprocess, filler is recyclable during maintenance utilizes again, thereby has reduced cost.
Second technical problem to be solved by this invention is: a kind of method of regulating volume after the power supply thermal expansion is provided; When this method has solved power work effectively; Because the Volume Changes that the hot caused thermal expansion that device produces brings; Make the power supply internal and external pressure balance, thereby significantly improved the waterproof ability of power supply.In order to solve above-mentioned technical problem; The present invention proposes a kind of LED driving power waterproof and heat radiation structure device; Comprise power shell, be useful on the cavity that the power circuit components and parts are set in the power shell, the end of power shell is provided with the foot rest of its port of sealing; And being filled with the insulating heat-conductive filling liquid in the said cavity, the said power circuit components and parts that are arranged in the cavity are immersed in this insulating heat-conductive filling liquid; The sealed at both ends of said power shell is provided with the Seal Oil diaphragm in the foot rest inboard, the flexible resilient material of the material of Seal Oil diaphragm for stretching; Oily diaphragm cavity is arranged on the Seal Oil diaphragm; On foot rest, be provided with oily diaphragm spiracle, oily diaphragm spiracle makes oily diaphragm cavity and power supply exterior, and Seal Oil diaphragm and foot rest are formed breathing bag; When breathing bag presented breathing state, its volume can change.Preferably: said Seal Oil diaphragm fuses with the sealing ring of the port of the power shell that is used to seal the foot rest place.Preferably: outwards protrude the centre of said foot rest, and said oily diaphragm spiracle is located at the centre of foot rest.Preferably: the port of said power shell is provided with the screw position, and said foot rest is fixed on the power shell through screw.Preferably: axial strip projected parts thing is arranged on the surface of said power shell.Preferably: the said outer casing of power supply hollow cylinder that is square.
The invention provides outdoor driving power waterproof of a kind of LED and heat radiation structure device; This constructional device comprises: the airtight power supply main body that outer casing of power supply, O-ring seal, Seal Oil diaphragm, insulating heat-conductive filling liquid, power supply PCB support, power supply COB (power supply appliance circuit) and fastening foot rest etc. are formed; The power supply main body closely links to each other shared Seal Oil diaphragm with breathing bag that can breathing.The heat that produces during power work brings to the power shell surface radiating by the insulating heat-conductive filling liquid, and is regulated because the power supply body volume of expanding with heat and contract with cold and causing by the breathing bag that can collapse.The power circuit components and parts are immersed in the insulating heat-conductive filling liquid, the heat that produces when taking away components and parts work more easily.The insulating heat-conductive filling liquid produces extruding at the Shi Buhui that expands with heat and contract with cold to the power circuit components and parts.Breathing bag volume when breathing can change.During breathing and the power supply exterior, the balance external and internal pressure.The power supply main body links to each other in the power shell inner tight with breathing bag that can breathing, and volume breathing is opposed complementary each other.
The present invention provides the breathing bag constructional device that a kind of LED driving power can breathing, and this constructional device comprises: the Seal Oil diaphragm has the fastening foot rest of oily diaphragm spiracle, and breathing bag that can breathing closely links to each other shared Seal Oil diaphragm with the power supply main body.
Preferably: said insulating heat-conductive filling liquid and utilization thereof.
Preferably: said Seal Oil diaphragm, process by flexible resilient material, fusing with sealing ring becomes the hollow utricule that can stretch.
Preferably: the said fastening foot rest that has oily diaphragm spiracle, with the Seal Oil diaphragm form can breathing breathing bag, oily diaphragm spiracle and power supply exterior satisfy the Volume Changes of power supply main body, hollow balloon and balance power supply external and internal pressure.
Preferably: said breathing bag and power supply main body that can breathing, both closely link to each other, the constructional device of shared Seal Oil diaphragm.
Beneficial effect of the present invention is following:
Compare prior art, the LED driving power discharges water and heat radiation structure device, and the heat dissipation problem when having solved power work has effectively reduced the temperature rise of power supply, has prolonged power source life; Avoided because thermal expansion to the extruding that components and parts produce, has improved the reliability of power supply; Embedding operation when being easy to power supply production, maintenance difficult after the solution embedding, and the recyclable utilization again of filler, thus reduced cost.
