Abstract
The invention provides a light-emitting diode (LED) outdoor lighting lamp driving power supply working in a low-temperature environment and belongs to the technical field of a lighting lamp driving power supply. The input end of a driving power module is connected with an external circuit; a first control switch is connected between the driving power module and the external circuit in series; a plurality of heating resistors are connected in series and are arranged at the periphery of the driving power module; the plurality of heating resistors connected in series are connected with the external circuit; and a second control switch is connected between the heating resistors and the external circuit in series. In the conventional driving power module, a resistor group with high heating characteristic is distributed at the periphery of an electronic device which becomes invalid easily in the low-temperature environment to form a series loop, so that normal operation of the driving power module is guaranteed. If the using environment is severe, the driving power module generate heat which is not enough to maintain the internal environment temperature to be above the normal operation temperature point of the device, an auxiliary heating circuit starts again and auxiliarily heats the electronic device, and normal operation of the electronic device is guaranteed.
Description
Technical field
The present invention relates to the LED outdoor lighting lamp driving power source of working in a kind of low temperature environment, belong to illuminating lamp driving power technical field.
Background technology
Along with the continuous development of country's " semiconductor lighting engineering " and deepening continuously of " energy-saving and emission-reduction ", " low-carbon economy ", light efficiency surpasses the great power LED of 100lm/W generally to be admitted as the development trend of road lighting and outdoor lighting.But the LED outdoor lighting has certain particularity under cold ground applied environment; Wherein relatively distinct issues be LED outdoor lighting light fixture driving power to the north of the mahjong city be that (ambient temperature can reach subzero 30 degrees centigrade) usually lost efficacy in the cold environment of representative, cause lighting to start unusually.This problem has had a strong impact on the promotion and application of LED outdoor lighting lamp.
Reliability and job stability when the driving power of existing LED outdoor lighting structure is not considered device at low-temperature condition in the parts selection process of design phase; Characteristic generation significant change under the part key components and parts low temperature environment; Cause the drive unit can't cold-starting or normal operation, the concrete reason of initiating failure mainly contains following several respects:
(1) switching tube of realizing invert function all can reduce in the density and the activity of cryogenic conditions download stream, and therefore the start-up point of overload protection also can reduce.
(2) electrochemical capacitor electrolyte freezes at low temperatures, loses capacity effect (only there is ionic polarization at this moment in the ion in the solution), no load capacity.
(3) the light lotus root device of part type can't operate as normal under low-temperature condition.
(4) input prevents the thermistor of surge current, and resistance becomes big (be normal temperature 3～5 times) at low temperatures, also can cause low temperature normally to start.
Select the better device of temperature characterisitic can alleviate above problem to a certain extent, but can improve the cost of drive unit.In addition, when ambient temperature was more harsh, this method still can not guarantee the operate as normal of driving power.
Summary of the invention
The objective of the invention is in cold environment, usually to lose efficacy, cause lighting to start unusual problem, and then the LED outdoor lighting of working in a kind of low temperature environment lamp driving power source is provided for the driving power that solves existing LED outdoor lighting light fixture.
The objective of the invention is to realize through following technical scheme:
The LED outdoor lighting lamp driving power source of working in a kind of low temperature environment; Comprise: driving power module, external circuits, first control switch, second control switch and some heating resistors; The input of said driving power module is connected with external circuits; Be serially connected with first control switch between driving power module and the external circuits; Some heating resistors be connected in series and be arranged on the driving power module around, the some heating resistors that are connected in series are connected with external circuits, are serially connected with second control switch between heating resistor and the external circuits.
The present invention has the following advantages: distributing around the electronic device that the present invention is prone in low temperature environment, lose efficacy in existing driving power module has the resistance crowd of better heat generation characteristic and forms series loop.Guarantee driving power module operate as normal.Like environment for use when comparatively abominable, driving power module self heat production still is not enough to keep interior environment temperature and puts when above in the device normal working temperature, and the assistant heating circuit will start once more, and electronic device is carried out assistant heating, guarantee its operate as normal.
Description of drawings
Fig. 1 is the structural representation of the LED outdoor lighting lamp driving power source of working in a kind of low temperature environment of the present invention.
Reference numeral 1 among the figure is a power output end.
Embodiment
To combine accompanying drawing that the present invention is done further detailed description below: present embodiment provided detailed execution mode, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.
As shown in Figure 1; The LED outdoor lighting lamp driving power source of working in the related a kind of low temperature environment of present embodiment; Comprise: driving power module 2, external circuits 3, first control switch 4, second control switch 5 and some heating resistors 7; The input of said driving power module 2 is connected with external circuits 3, is serially connected with first control switch 4 between driving power module 2 and the external circuits 3, some heating resistors 7 be connected in series and be arranged on driving power module 2 around; The some heating resistors 7 that are connected in series are connected with external circuits 3, are serially connected with second control switch 5 between heating resistor 7 and the external circuits 3.
