Abstract
The utility model discloses an oil-cooled power supply for LED lamps, which relates to the field of lighting apparatuses for road traffic. The oil-cooled power supply for the LED lamp comprises an enclosed shell body filled with insulating cooling oil, an electronic component and a circuit board both fixed and immersed inside the shell body. A thermal expansion space is arranged between the cooling oil and the shell body, and an electronic component connecting wire is led out of the shell body. The oil-cooled power supply for LED lamps uses the liquid cooling oil (which can be transformer oil) with strong insulting property, good heat conducting effect and non-corrosive quality, and the liquid cooling oil is filled into the shell body of the power supply so as to lead the electronic component to work in liquid environment. The inside of the power supply is not filled with the transformer oil totally, and a specified space is available for thermal expansion and cool shrinking of the oil. The oil-cooled power supply for the LED lamp has the advantages that heat generated in this way can be transferred out of the shell body of the power supply in time to be dissipated by convective air. The oil-cooled power supply for the LED lamp has good heat dissipating effect, effectively prolongs service life of product, and reduces maintenance cost.
Description
Technical field
The utility model relates to the power supply architecture of high-power LED lamp, is used for the road traffic lighting field.
Background technology
The existing high-power LED lamp relevant with this new technique, be not subjected to the interference of circuit for the ease of light path, its power supply architecture and light-source structure branch usually are arranged, and two kinds of situations are generally arranged, and light source and power supply place in the lamp outer casing cavity together or light source is arranged on outside the lamp casing.The power supply of so independent setting is water-tight fully, but is unfavorable for heat radiation.Especially LED street lamp, the general efficient of using on the LED street lamp of large power supply means that the electric energy that has about 10% has changed into heat about 90% at present.And because the needs of structure and waterproof, power supply will have extraordinary sealing, and electronic component can not directly contact with outer casing of power supply, makes the inner heat that produces of power supply in time do not derived, to distribute like this.Cause the electronic component temperature of the inside to exceed tens degree than the temperature of shell.Make that like this failure rate of power supply is high.
The utility model content
The purpose of this utility model is to provide but power supply of the good oil cooling that is used for the LED light fixture of a kind of radiating effect.
The technical scheme that provides of the utility model is for achieving the above object, the oil cooling that is used for the LED light fixture is power supply but, it comprises the housing of a sealing, fill the insulation cold oil in its housing, submergence is mounted on electronic devices and components and the circuit board in the housing, the heat expansion space is set between cold oil and housing, and electronic devices and components connect lead and draw outside the housing.
Compare with existing LED lamp power, the utility model selects that a kind of insulation property are strong, good heat conduction effect, do not have corrosive liquid cooled oil, can be the transformer oil of specialty, liquid cooled oil is added in the power shell, make electronic devices and components be operated in liquid environment.Transformer oil is not exclusively solid with power supply, reserves the certain space fuel feeding and expands with heat and contract with cold.Advantage is that the heat that produces so just can in time export to the shell of power supply, is taken away by the air of convection current then.Has better heat radiating effect.
Below in conjunction with accompanying drawing the most preferred technical scheme of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation that is used for the cold oil power supply of LED light fixture.
Embodiment
In order to understand preferred version of the present utility model, make those skilled in the art can realize the utility model, see also Fig. 1.
The oil cooling that is used for the LED light fixture is power supply but, it comprises the housing 1 of sealing, fills insulation cold oil 2 in its housing 1, and submergence is mounted on electronic devices and components 3 and the circuit board 4 in the housing, 1 of cold oil 2 and housing are provided with heat expansion space 5, and electronic devices and components 3 connect lead and draw outside the housing 1.This novel power shell that relates to has good water-tight structure, enough prevents the leakage problem of cold oil.Also can further add waterproof constructions such as sealing ring.
The LED lamp power that the utility model provides; the profile of its light source module, size are not limited to foregoing description and illustrations openly limits, if the variation scheme of other external shape ought to be among this novel protected scope based on the scheme of power module inside filling cold oil.
Claims (1)
1. but power supply of an oil cooling that is used for the LED light fixture, it comprises the housing of a sealing, it is characterized in that: fill the insulation cold oil in its housing, submergence is mounted on electronic devices and components and the circuit board in the housing, the heat expansion space is set between cold oil and housing, and electronic devices and components connect lead and draw outside the housing.
