Specific embodiment
Embodiment 1
Please refer to figure, in the embodiment of the present invention, a kind of radiating subassembly for LED illumination lamp, the shell including cylindrical structure
1, several are evenly distributed on the bottom of shell 1 through upper and lower heat-conducting block 5, the material of heat-conducting block 5 is copper, and heat-conducting block 5 is stretched
Entering into LED illumination lamp, heat is sent in shell 1, the bottom of shell 1, which is screwed, to be mounted in LED illumination lamp,
By 5 heat radiator of heat-conducting block, while radiating subassembly can be avoided and fall into dust in LED illumination lamp, keep lamp interior safety
Operation, prolongs the service life；It is uniformly provided with several side heat release holes 4 on the side wall of shell 1, internal hot-air is sent
Out, the air flowing in shell 1 is kept, is radiated.
Heat sink 2 there are two semicircular plate-form structure is set on the top of the shell 1, and two heat sinks 2 are horizontal right
The circle with 1 inner wall same size of shell is formed after neat, the top of shell 1 is covered, dust is avoided to enter in shell 1, is radiated
Plate 2 is arranged on shell 1 by the shaft 3 being rotatably installed on shell 1, makes 3 rotation around the shaft of heat sink 2, on the top of shell 1
Portion can outwardly open；It is fixedly installed in the cylinder-like structure coaxial with shell 1 on the center in the shell 1
Heart cylinder 6, the upper end of central tube 6 is concordant with 1 upper end of shell, and the free end of two heat sinks 2 is erected at the top of central tube 6
Portion, two heat sinks 2 keep in the horizontal direction, making two heat sinks 2 in same level when on central tube 6；Institute
It states and is equipped with one in central tube 6 full of the swelling gasbag 8 in central tube 6, under room temperature (20-25 DEG C) environment, the expansion gas
The top of capsule 8 is concordant with the top of central tube 6, after when gases are heated, they expand in swelling gasbag 8, pushes up swelling gasbag 8 upwards
It rises, 2 free end of heat sink complained to the higher authorities about an injustice and request fair settlement is jacked up, so that two heat sinks 2 be opened, convenient for radiating in shell 1.
It is provided with mutually matched seal groove 11 and sealing strip 12 on two heat sinks 2, is located at by sealing strip 12 close
Two heat sinks 2 are sealed in sealing groove 11, inside is avoided to enter dust, when seal groove 11 and the disengaging of sealing strip 12, make two to dissipate
The opening of hot plate 2 increases, and realizes heat dissipation；The distribution of specific seal groove 11 and sealing strip 12, on the heat sink 2 of the left and right sides
Sealing strip 12 or so is arranged alternately, and the distance between two adjacent sealing strips 12 are equal.
In this way, radiating subassembly, after being mounted on the top of LED illumination lamp, heat-conducting block 5 extend into the lampshade of LED illumination lamp
Heat derives interior, that inside is generated, are sent in shell 1, are radiated by the air flowed in shell 1, at this time component
In LED illumination lamp, it can prevent to influence to radiate using dust is fallen into LED illumination lamp for a long time, avoid LED illumination lamp
It is interior to enter dust, it is the more heat of accumulated inside when LED illumination lamp uses for a long time, internal temperature increases, and makes swelling gasbag 8
Interior air expansion, two 2 free ends of heat sink of upper end are jacked up, seal against each other after jack-up upwards using swelling gasbag 8
Seal groove 11 and sealing strip 12 separate, and seal groove 11 leaks out, and increases the area of the top heat dissipation of shell 1, improve internal sky
Flow of air is adjusted according to temperature self-adaptation and is radiated, and temperature is higher, and the expansion of swelling gasbag 8 is bigger, seal groove 11 and sealing strip 12
The degree of disengaging is bigger, and the area that seal groove 11 leaks out is also bigger, to improve heat dissipation effect.
