Abstract
The invention discloses an outdoor light emitting diode (LED) driving power supply, which comprises an LED driving power supply module (2), wherein a power supply shell (1) is arranged outside the LED driving power supply module (2); in the power supply shell (1), solidified heat-conducting silicon rubber (8) is arranged between the LED driving power supply module (2) and the power supply shell (1); and the solidified heat-conducting silicon rubber (8) is adhered to the LED driving power supply module (2) and the power supply shell (1). Because the solidified heat-conducting silicon rubber (8) is arranged between the LED driving power supply module (2) and the power supply shell (1), the outdoor LED driving power supply has the advantages that: the invasion of water vapour and dust is prevented, and heat which is generated by the LED driving power supply module (2) can be conducted to a surface of the power supply shell (1) immediately, uniformly and quickly and transferred to air quickly, so the two key technical problems of radiation and water prevention of the outdoor LED driving power supply are solved, and the service life of the outdoor LED driving power supply is effectively prolonged.
Description
Affiliated technical field
The present invention relates to outdoor LED driving power technical field of structures, especially the waterproof of free-standing driving power such as LED street lamp, LED Tunnel Lamp, the safeguard structure technology of heat radiation.
Background technology
LED (light emitting diode) illumination becomes the mainstream technology of green energy conservation illumination at present just rapidly with advantages such as its light efficiency are good, energy consumption is low, the life-span is long.The large-scale redevelopment conventional road lamp that has just begun, the LED street lamp of Tunnel Lamp, LED Tunnel Lamp all use the outdoor type LED driving power, and the length of its working life is directly restricting the effect that green energy conservation is transformed.The power of most of outdoor type LED driving power is 60 to 300 watts, and inner to produce heat higher, uses out of doors for a long time in addition, is subjected to intrusion such as steam, dust easily and causes damage.Therefore heat radiation and waterproof are two importances of outdoor type LED driving power protection, also are the key factors that improves outdoor type LED driving power working life.
On February 24th, 2010, Chinese invention patent disclosed, that publication number is CN201414270 disclosed a kind of outdoor type LED lamp power supply, sealed lid of power supply driver and sealing strip are enclosed in the shell inner waterproofing, and rely on the radiating fin of case surface to dispel the heat, because the heat that power supply driver produces can't effectively be delivered to outer casing of power supply by adiabatic medium air, cause heat accumulation in the power shell, temperature to rise and the electronic devices and components working life is descended easily; On March 10th, 2010, Chinese invention patent disclosed, that publication number is CN201421049 disclosed LED road lamp power supply radiator structure, this patent adopts the heat radiation of thermal column structure, it is little also to have the heat conduction contact area, it is inhomogeneous to dispel the heat, thereby causes power supply driver subregion temperature too high and damage easily.
Summary of the invention
The objective of the invention is provides a kind of outdoor type LED driving power in order to overcome the deficiencies in the prior art, and it can improve outdoor type LED driving power radiating effect, reaches waterproof, protection against the tide, protection effect such as dustproof simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of outdoor type LED driving power, comprise LED driving power module, described LED driving power module is outside equipped with the outer casing of power supply with power supply lower port and power supply upper port, the power supply lower port of outer casing of power supply and power supply upper port are respectively arranged with power supply lower sealing cover and power supply top cover labyrinth, it is characterized in that in outer casing of power supply it being the heat-conducting silicon rubber that has solidified between the LED driving power module and outer casing of power supply, described heat-conducting silicon rubber and LED driving power module, outer casing of power supply are bonding.
Further, described heat-conducting silicon rubber thermal conductivity factor is 0.6～0.9W/ (mK), and liquid silastic viscosity is 6000～10000mPa.s before solidifying.
The invention has the beneficial effects as follows, the sealed lid of LED driving power module is enclosed in the outer casing of power supply, and fill outer casing of power supply inside with heat-conducting liquid silicon rubber, bonding after room temperature or the heating cure with LED driving power module, outer casing of power supply, prevent that steam, dust etc. from entering outdoor type LED driving power inside; Heat-conducting silicon rubber after solidifying in addition can conduct to the heat that LED driving power module produces evenly, fast the outer casing of power supply surface and transfer to rapidly in the air, solved effectively in the outer casing of power supply of prior art adiabatic medium air intercept conduct heat, thermal column conducts heat inhomogeneous and cause power supply in the too high and problem of damage of local temperature; Heat-conducting silicon rubber after solidifying in addition has good weather-proof stability, has improved outdoor type LED driving power working life.
