It should be noted that since the installation cylinder is directly bonded setting with the radiating sleeve of the cooling mechanism,
Merely by fixing the radiating sleeve of the installation cylinder and the cooling mechanism by the fastener, it is more difficult to setting
The LED lamp bead for being placed in the installation cylinder plays a protective role, for example, working as the entirety of the front end type LED radiating lamp
When structure is by external impacts, the radiating sleeve of the cooling mechanism and the installation cylinder can generate covibration, i.e. institute
Stating installation cylinder will appear seismism, the contact position of the radiating sleeve of the especially described cooling mechanism and the installation cylinder
Place is set, opposite effect power will be respectively generated, and then the vibration problems of the installation cylinder can be aggravated, is easy to justify the installation
The LED lamp bead installed on cylinder causes related vibration, or even can shake bad LED lamp bead, and the especially described LED lamp bead is as accurate electricity
Subcomponent, it is necessary to buffer protection measure be carried out to the LED lamp bead, the LED lamp bead is applied with buffering the installation cylinder
The active force or vibration force added is based on this to resist external impacts caused by front end type LED radiating lamp described in outer bound pair, needs
The cushion performance of the installation cylinder is improved, to reduce the installation cylinder and the cooling mechanism in the front end type LED
Resonance problem when radiating lamp is by external impacts for playing buffer function, and then can preferably protect the LED light
Pearl.Therefore, it is necessary to the cushion performance of the installation cylinder be improved, preferably to protect the LED lamp bead, and it also requires really
The installation cylinder is protected normally to radiate and/or heating conduction.
In order to improve the cushion performance of the installation cylinder, preferably to protect the LED lamp bead, and it also requires ensuring
The installation cylinder normally radiates and/or heating conduction, for example, the installation cylinder of an embodiment, including successively fold
The heat dissipation film layer set, heat transfer film layer and buffering film layer are added, for example, the heat dissipation film layer, the heat transfer film layer and the buffering
Film layer all has ring structure, and three forms the installation cylinder after being sequentially overlapped fitting.For example, the cooling mechanism with it is described
Film layer fitting is buffered, the LED lamp bead is set in the buffering film layer, and the heat that the LED lamp bead generates is transferred directly to
In the buffering film layer, in the heat transfer to the buffering film layer that the LED lamp bead generates heat, at this point, heat scatters and disappears
There are two paths, one of them is, the buffering film layer is dissipated in the heat transfer to the cooling mechanism of a part by described
Heat engine structure carries out the heat of the part lost；The other is in order to improve heat dissipation effect, the buffering film layer is by another part
Heat transfer to the heat transfer film layer on, and directly by the heat transfer film layer quickly and in time will be in the buffering film layer
In heat transfer to the heat dissipation film layer, the heat of this part is carried out lost by the heat dissipation film layer.That is, described dissipate
Heat engine structure primarily serves the rapid cooling effect of front end heat dissipation type, and the installation cylinder carries out the auxiliary heat dissipation effect of holohedral form,
In such manner, it is possible to further increase the integral heat sink effect of the front end type LED radiating lamp, it can satisfy the big lamps and lanterns of calorific value
Demand.
It is further preferred that on the one hand the buffering film layer plays conductive force, for issue the lamp bead
Heat is transferred to respectively in the cooling mechanism and the heat transfer film layer；On the other hand, it is also used to play buffer function, it can
The active force that the radiating sleeve from the cooling mechanism applies the installation cylinder is absorbed, to reduce the installation cylinder
Strenuous vibration, and then preferably the LED lamp bead is protected, to extend the service life of the LED lamp bead.
In order to improve the cushion performance of the installation cylinder, preferably to protect the LED lamp bead, and it also requires ensuring
The installation cylinder normally radiates and/or heating conduction, for example, referring to Fig. 10, installation cylinder 100 includes buffering film layer
130, film layer 140 of conducting heat and heat dissipation film layer 150, the LED lamp bead are set to side of the buffering film layer 130 far from heat transfer film layer 140
The radiating sleeve in face, the cooling mechanism is bonded with buffering film layer 250 far from the side of heat transfer film layer 240.
In order to enable the heat dissipation film layer, the heat transfer film layer and the buffering film layer are more stepped up in combination between each other
It is close, for example, the side of the heat dissipation film layer towards the heat transfer film layer is provided with multiple first engaging portions, the heat transfer film layer court
Multiple first embedding slots are offered to the side of the heat dissipation film layer, each engaging portion corresponds described embedding embedded at one
It sets in slot, and the inner sidewall of the lateral wall of first engaging portion and first embedding slot is in close contact, the heat transfer film layer
The side of the buffering film layer is provided with multiple second engaging portions, the film layer that buffers is towards the side of the heat transfer film layer
Multiple second embedding slots are offered, each second engaging portion corresponds in second embedding slot, in this way,
It can be improved the bite force and contact area between each, and then enable to the heat dissipation film layer, the heat transfer film layer and institute
It is even closer in combination between each other to state buffering film layer.
It is appreciated that the heat dissipation film layer as directly with the structure sheaf that is directly contacted of film layer that conducts heat, therefore,
The heat dissipation performance for first ensuring the heat dissipation film layer is had to, so that the heat dissipation film layer can be quickly and in time by the biography
Heat that hotting mask layer is transmitted to carries out quickly and in time lost, i.e., the described heat dissipation film layer must have preferable thermal diffusivity
Can, to share the thermic load for bearing the heat that the cooling mechanism generates the LED lamp bead, and on this basis, also need
The heat dissipation film layer is set to have both certain cushion performance, it is whole to play for cooperating the heat transfer film layer and the buffering film layer
The effect of body damping, preferably to protect the LED lamp bead.
For example, in the installation cylinder of the front end type LED radiating lamp of an embodiment, the heat dissipation film layer packet
