Description
Technical field
The present invention relates to a kind of radiator, and in particular to a kind of radiator of LED light.
Background technology
LED is a kind of semiconductor that can convert electrical energy into visible ray, its energy consumption is only the 1/l0 of incandescent lamp, common section
Can lamp 1/40 LED light in addition to there are environmental protection and energy saving, also with long lifespan, light efficiency is high, radiationless many advantages, such as.
Therefore, upgraded products of the LED as next generation's illumination, is the new industry with great potential.
The application of LED is constantly subjected to the puzzlement of heat dissipation problem, and heat dissipation problem seriously affects light efficiency and the longevity of LED light source
Life, the heat dissipation of LED light will generally rely on radiator, and traditional radiator is typically all the cylindrical shape closed, and outside can be distributed one
A little fins, although having reached basic heat dissipation purpose, radiator close so that radiator inner air can not in time with outside
The air circulation on boundary, just causes radiating efficiency low, causes LED light source and power source temperature excessive, so as to influence the light efficiency of LED
And the service life, and in order to make radiator effect become more preferable, existing radiator can also open up heat emission hole on the outer wall, and heat emission hole is set
That counts is too big, and radiator has not had the effect of dust and moisture again, and heat emission hole designs too small, though play to LED light
The effect of dust and moisture, but what the heat of LED light generation still can not be unobstructed distributes, and also heat emission hole is too small, the time
One length, it is easy to can be blocked by dust, cause heat emission hole not reach the purpose of heat dissipation, this certainly will also influence the use of LED light
Service life.
The content of the invention
The invention is intended to a kind of good heat dissipation effect is provided and can dust and moisture LED light radiator.
The radiator of LED light in this programme, including heat dissipating housing, heat dissipating housing include heat dissipation outer cover and are located at heat dissipation outer cover
The homonymy of interior heat dissipation inner cover, heat dissipation outer cover and the inner cover that radiates is equipped with two opposite ventilating openings, it is characterised in that heat dissipation outer cover
Expander is equipped between heat dissipation inner cover, expander is equipped with the contiguous block for being closed in ventilating opening, connection close to the side of ventilating opening
Through hole is provided with close to the side of expander on block, the first elastic component is connected between contiguous block and heat dissipation outer cover, radiates on outer cover
Equipped with power module, heat dissipation inner cover is equipped with connects electric block with what power module coordinated, connects electric block and is connected with fan, fan is located in heat dissipation
Cover inner side, expander are equipped with conducting block close to the side of power module, the second elastic component are connected between conducting block and heat dissipation outer cover.
The technical principle of this programme and have the beneficial effect that：When lamp is not turned on, the temperature of lamp is room temperature, and expander will not be swollen
Bulging deformation, contiguous block still close two ventilating openings, and the dust of air will not be entered in heat dissipating housing, played daily
Dust-proof effect, conducting block can also keep in situ, not with power module and connecing electric block and being connected.
When needing to use lamp, lamp is opened, the temperature of lamp constantly raises；When temperature is not high, expander still will not be swollen
Bulging deformation, contiguous block still close two ventilating openings, and conducting block can also keep in situ, not with power module and connecing electric block and connecting
Logical, heat dissipating housing ensures that the heat dissipation of lamp.
When temperature continues for raising, when temperature becomes very high, expander will by deformation affected by temperature, expander
It is drivingly connected block to move to the direction away from expander, the first elastic component will be compressed, and the through hole on contiguous block will lead to two
Air port communicates, and inside the heat sink hot-air is in contact circulation with cool exterior air, make the heat of inside the heat sink be more easy to flow to it is scattered
Heat cover is exterior, so as to improve heat dissipation effect；Expander dilatancy can also drive conducting block to be transported to the direction away from expander
Dynamic, the second elastic component will be compressed, and conducting block will be with power module and connecing electric block joint, and connecing electric block will power on, fan
It will start to rotate, fan starts to dry, and hot wind will flow to the outside of heat dissipating housing by ventilating opening and through hole, so as to improve heat
The speed of outflow is measured, also further increases heat dissipation effect.
When lamp is closed, the constant temperature of lamp reduces, and expander will restore to the original state, and ventilating opening will be closed, conducting block
Will be with power module and connecing electric block and separating, fan will shut down, and hot-air, process of the lamp in cooling will have been retained in heat dissipating housing
In, it will not be contacted for a long time with cold air, play moisture-proof effect.
Further, expander is rubber block, rubber block can expanded by heating, after temperature is reduced to room temperature, and return to original state
It can play the role of being drivingly connected block and conducting block.
Further, the position of fan and two ventilating openings is located along the same line, this setting, can make hot wind directly from ventilation
Mouth outflow, during which will not be subject to the obstruction of heat dissipating housing and reduce wind speed, maintain radiating rate so that heat dissipation effect is more preferable.
Further, the first elastic component and the second elastic component are spring, and spring is a kind of machinery for utilizing elasticity come work
Part, part deforms upon under external force made of elastic material, restores to the original state again after removing external force, is connected to connection
Spring on block, can promote connection block reset when expander restores to the original state；The spring being connected on conducting block, can expand
When body restores to the original state, conductive block reset is promoted.
Further, radiate and be installed with fixed block between outer cover and heat dissipation inner cover, the first elastic component and the second elastic component with
Fixed block is connected, and fixed block can be such that the first elastic component and the second elastic component is easily fixed, and reduce the first elastic component and the second bullet
Property the fixed difficulty of part connection.
