Abstract
The utility model discloses a novel cooling fin. The novel cooling fin and a fixed seat form a T-shaped structure; positioning holes and avoiding structures are formed in the fixed seat; the positioning holes are oval and the avoiding structures are grooves with one ends being opened. A cooling fin mechanism is changed to be in a movable type from a fixed type by means of changing the appearance structure of the cooling fin and adjusting the shape of the fixed holes; after an oval screw hole of the fixed seat of the cooling fin is assembled with a light guide plate, the relative spacing of an LED (light emitting diode) and the light guide plate is precisely controlled by means of adjusting the position of the cooling fin mechanism, and the variation of the spacing can be controlled within a range from +0.05mm to -0.05mm. The cooling fin has the advantages of being simple to operate and accurate in control.
Description
Technical field
The utility model relates to the fin field in the LED-backlit module, is specially a kind of heat radiating fin structure.
Background technology
In the LED-backlit module, LED changes whole optical energy and the module flat each point Energy distribution trend that can affect backlight module apart from the LGP spacing, the function of fin is mainly the fixed light bar and the heat that sends when LED is lighted is derived, and avoids excess Temperature to cause the functional issues such as LED damage.In the structure of fin, fin and holder are designed to " L " type structure at present, can't adjust position, cause the distance values of LED and LGP to be subjected to the impact of mechanisms' collocation tolerances such as base, LGP, fin, spacing variation meeting causes direct impact to module optics, the variation of module optics can cause the machine development difficulty to increase, the series of problems such as the bad scrappage increase of LGP optics.
The utility model content
In order to overcome the defect of above-mentioned prior art, it is a kind of simple in structure, easy to operate that the utility model provides, the Novel heat sink structure of being convenient to adjust.
The utility model is realized by following scheme, a kind of radiating fin, described fin elongated surfaces is provided with some ellipse locating holes, some avoiding structure holders are the tee T structure, it is characterized in that: described holder is provided with locating hole and avoiding structure, described locating hole is oval, and described avoiding structure is the groove of an end opening.
The utlity model has in sum following beneficial effect: owing to passing through to change the fin surface structure and adjust the fixing hole shape, with cooling rib arrangement by fixed change to movable, change to removable mechanism's part, can accurately control LED and LGP relative spacing by adjusting the cooling rib arrangement position after the assembling LGP, variation can be controlled in +/-0.05mm.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure top view;
Wherein: 1-fin, 2-locating hole, 3-avoiding structure
The specific embodiment
As shown in Figure 1-2, a kind of radiating fin, described fin elongated surfaces is provided with some ellipse locating holes, some avoiding structure holders are the tee T structure, it is characterized in that: described holder is provided with locating hole and avoiding structure, described locating hole is oval, and described avoiding structure is the groove of an end opening.
The utility model is to implement like this, by changing the fin surface structure and adjusting the fixing hole shape, with cooling rib arrangement by fixed change to movable, change to removable mechanism's part, can accurately control LED and LGP relative spacing by adjusting the cooling rib arrangement position after the assembling LGP, variation can be controlled in +/-0.05mm.For stablizing the optics of backlight module, the light that LED sends is transferred in LGP equably, can also add a thin slice between LED and LGP, the size of this thin slice can be determined with design load.The oval screw hole that arranges on fin, can, by adjusting fin,, near thin slice, then lock screw to LED., greater than the right, can increase the distance between LED and LGP as the optics left side of net-pont design, make the homogeneity of backlight module reach requirement, vice versa.Optics as the upper left corner is higher, can strengthen the distance between LED and LGP top, remains unchanged below, and vice versa.
It should be noted that finally: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in claim scope of the present utility model.
Claims (3)
