Description
Technical field
The present invention relates to the integral LED lamp heat radiation module that a kind of active heat removal and passive heat dissipation combine, more particularly to
Small, power is big and radiating element needed for being independently mounted on LED lamp module.
Background technology
At present, high-power LED lamps and lanterns need secure heat dissipation to design.Existing majority high-power LED lamp product is general
Using direct using the radiating mode passively to radiate, generally aluminum or aluminum alloy material is (using the quality of aluminium is relatively light, heat conduction
The characteristics of better performances) size according to required radiating element power, radiator of the assembling with respective volume and heat dissipation area,
It will need the device dress to radiate on a heat sink, heat exported from device by heat transfer and is gone.Such a mode, heat dissipation effect with
The heat dissipation area of radiator is related, and for the device that radiating surface is larger, heat transfer is than very fast.Therefore, powerful radiator body
Product can be larger, and product design also accordingly becomes larger.Not only unsightly, but also it is not easy to install and uses.Moreover, for radiating surface very little,
The device (such as COB LED components) that heat generating spot is concentrated, since contact area is small, heat is difficult quickly by the contact of radiator
Face is transmitted on radiator, even if the heat dissipation area of radiator is sufficiently large in such cases, heat dissipation effect is also undesirable, greatly
Influence heat dissipation performance and device lifetime.And hot pipe technique is used, the heat of radiator and heating device contact surface can be passed through
Heat pipe conducts rapidly, to achieve the purpose that heat dissipation.But it has the drawback that the heat pipe processing technology of good heat conductivity will
Ask higher, cost is also very high, is difficult to realize the long-life.
Utility model content
The utility model provides a kind of assembling radiating structure of LED light, is that it is that active heat removal and passive heat dissipation combine
Integral type, it not only has the characteristics that small, light-weight, perfect heat-dissipating, and convenient installation and replacement.The utility model
Technical solution is：By an active heat sink, a passive radiator and fixing device and heating device composition；Described consolidates
Determine device to be made of screw, upper mounted plate and support column；The heating device is installed on the heat sink of passive radiator；Institute
The passive radiator stated is made of heat sink and radiator shutter；The radiator shutter of the passive radiator is evenly spaced arrangement
Between upper mounted plate and heat sink, and the air outlet of active heat sink is faced, locked by screw and support column；The master
Dynamic radiator is installed on upper mounted plate；The air-flow of active heat sink blowout will be transmitted to heat on radiator blade and take away, with
Achieve the purpose that heat dissipation.
In addition, in order to limit, the active heat sink is MEMS vibration membrane structured heat sinks, the passive radiator
Section bar is stretched for fine aluminium or aluminum alloy material.
The utility model is using the effect acquired by above technical scheme：Using newest MEMS active heat removals technology,
Quickly the heat being transmitted on passive radiator can quickly be exported, MEMS active heat sinks are small, and power is small, adopt
With vibration membrane structure, vibrating membrane vibration is driven by electromagnetic starter, the air-flow of generation is ejected by pneumostome, passes through air
Convection current reaches heat dissipation effect.At the same time using the effect of traditional passive radiator be by heat transfer out come, rather than needs lean on
It radiates, so can reduce much relative to traditional heat sinks volume.In addition, the weight of large-power lamp is concentrated mainly on
On radiator, therefore the weight of whole lamp can also be much less, so that shape is more beautiful, and be easily installed；Due to heat dissipation
The volume of device is all smaller, and shape can need progress appearance design according to actual product, without being limited by volume and weight,
Product design and performance boost are more conducive to, improves the heat dissipation effect of lamps and lanterns, improves the service life of lamps and lanterns.
Brief description of the drawings
