The heat radiating system of the LED light source has the advantages of being high in radiating efficiency, high-level in waterproof effect and dustproof effect, environment-friendly, long in service life and the like. Moreover, the installation is convenient, the materials are saved, the cost is lowered, and the universality is strong.
Description
Technical field
The utility model relates to a kind of cooling system of LED light source.
Background technology
The radiating mode of LED road-light light-source mainly contains at present: Natural Heat Convection, install the fan forced heat radiation additional, heat pipe and loop heat pipe heat radiation etc.All there is defect in these radiating modes: the fan cooling mode, and in circuit, without temperature control equipment, itself can produce heat, and, under the state of working long hours, can shorten its service life, not energy-conservation; The radiating effect of heat pipe is general, for high-power LED light source, can't meet radiating requirements; The fin radiating mode, it is limited because of surface area, effect or unsatisfactory, and also when the street lamp transformation is changed, whole road lamp cap replaces, and then changes a whole set of LED road lamp cap, so not only wastes material but also increases cost.
The utility model content
Technical problem to be solved in the utility model is to realize a kind of good heat dissipation effect, easy for installation, energy-saving material, the LED street lamp module group radiator of low cost of manufacture.
To achieve these goals, the technical solution adopted in the utility model is: a kind of LED light source cooling system, LED light source is fixed on one side, the aluminium base another side that aluminium base is provided with reflector and is fixed with aluminium radiator, is fixed with the fan to the aluminium radiator air blast on described aluminium base.
Described aluminium base is provided with temperature sensor, and described fan power supply input is provided with temperature controller, and described temperature sensor output temperature signal is to temperature controller.
Described aluminium base is provided with the high temperature breaker, the break-make of the driving power ac input end of described high temperature breaker control LED light source.
Described LED light source is in parallel and is formed by a plurality of lamp pearl strings, and described lamp pearl string is in series and is formed by a plurality of LED lamp pearls.
Between described aluminium base and aluminium radiator, and be equipped with the thermal conductive silicon glue-line between aluminium base and reflector.
The utility model has the advantage of that this LED light source cooling system has a radiating efficiency high, high-grade waterproof and dustproof effect, the advantage such as the environmental protection life-span is long, and also easy for installation, save material, reduce costs highly versatile.
The accompanying drawing explanation
Below the content of every width accompanying drawing expression in the utility model specification and the mark in figure are briefly described:
Fig. 1 is the cooling system exploded perspective view;
Fig. 2 is cooling system package assembly schematic diagram;
Fig. 3 is LED light source and cooling system circuit block diagram thereof;
Mark in above-mentioned figure is: 1, aluminium base; 2, LED lamp pearl; 3, aluminium radiator; 4, DC supply input; 5, screw; 6, fan, 7, temperature sensor; 8, high temperature breaker; 9, temperature controller; 10, driving power.
The specific embodiment
Referring to Fig. 1,2 known, LED light source is fixed on the one side that aluminium base 1 is provided with reflector, and aluminium base 1 another side is fixed with aluminium radiator 3, for improving radiating efficiency, between aluminium base 1 and aluminium radiator 3, and be equipped with the thermal conductive silicon glue-line between aluminium base 1 and reflector.Be fixed with the fan 6 to aluminium radiator 3 air blast on aluminium base 1, normally utilize the fixture of side to be gripped, be the state of fan 6 and aluminium base 1 clamping aluminium radiator 3.
Known referring to Fig. 3, LED light source is by driving power 10 power supplies, driving power 10 connects alternating current, temperature controller 9 seals in driving power 10 inlet wire L, electric current is through 6 power supplies of 9 pairs of fans of temperature controller, temperature sensor 7 and high temperature breaker 8 use heat conductive silica gels are close to the reflector surface of aluminium base 1, temperature sensor 7 output temperature signals are to temperature controller 9, high temperature breaker 8 is controlled the break-make of the driving power ac input end of LED light source, the work of fan 6 is attached to lip-deep temperature sensor 7 controls of reflector like this, in the time of can set temperature >=50 ℃, fan 6 work, otherwise stop, and make system possess overheat protection function by the lip-deep high temperature breaker 8 of reflector, during in temperature >=75 ℃, high temperature breaker 8 automatic disconnection driving power 10 power supplies, LED light source is not worked, now radiator fan 6 works on, LED light source has been protected in heat radiation effectively, reduced that LED lamp pearl 2 damages because of high temperature and the light decay problem has extended service life.
For further improving radiating effect, can use the small light pearl to replace the high-power lamp pearl, as shown in Figure 1, be fixed with lighting source in aluminium base 1 one side, another side is fixed on aluminium radiator 3 by the bolt 5 of surrounding, and for improving radiating efficiency, lighting source consists of some low-power LED lamp pearls 2, for example can adopt the 5050 LED lamp pearls that power is 0.2w, be in series and form lamp pearl string by least 20 LED lamp pearls 2 specifically, at least 4 lamp pearl strings formation lighting source that is in parallel, utilize and use 300 LED lamp pearls 2, every 60 LED lamp pearls, 2 series connection, and then five groups of lamp pearl connection in series-parallel form lighting source.Finally the DC supply input of lighting source 4 is connected and gets final product with the LED driving power 10 of appropriate power.LED lamp pearl 2 is welded on aluminium base 1, need to be at each LED lamp pearl 2 outer mounted lens after LED lamp pearl 2 is fixing, and lens are to be fixed on the aluminium base 1 of LED lamp pearl 2 both sides by glass cement.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
