Abstract
The utility model discloses a heat abstractor for an LED module, which comprises a case body for accommodating the LED module and the LED module formed by laminating in sequence a heat sink, a heat conducting film, a PCB plate and a veil; at least one double end stud is arranged between the case body and the heat sink, and a screwed hole is respectively arranged on two ends of the double end stud; and a through hole through which a screw passes is arranged at the position corresponding to the heat sink, the heat conducting film, the PCB plate and the veil. The LED module is fixed with the double end stud through a socket head cap screw in the front direction and is fixed with the double end stud through a retaining screw in the back direction of the case body. The heat abstractor for the LED module can be dismantled for maintenance from either the back or the front of the case body, and therefore, the maintenance work is simple and fast. At the same time, the heat abstractor has the advantages of convenient process and simple technology, thereby effectively improving production efficiency.
Description
Technical field
The utility model relates to led module, relates in particular to a kind of led module heat abstractor.
Background technology
Led board can send a large amount of heat energy when work, for avoiding the led board temperature too high, the most frequently used also is that most economical method is at the back side of led board dress a slice heat-dissipating aluminium plate.Present installation method is to adopt heat-dissipating aluminium plate to be crimped on self-clinching standoff, heat-dissipating aluminium plate and self-clinching standoff can't disassemble, pcb board in the led module is close to fixing by self-clinching standoff and heat-dissipating aluminium plate, heat-dissipating aluminium plate is to be embedded in the middle of the pcb board, can't take out.Objects such as the screw of led module by the casing back and casing are fixed.When needing repairing later on, can only can not accomplish to safeguard from the dismounting of casing back from the casing front.So significant limitation is arranged when safeguarding.
The utility model content
The utility model be to solve existing heat abstractor can not be from the problem of casing front demolition and maintenance, a kind of installation and maintenance of being convenient to are proposed, in all dismountable heat abstractor in casing front and back.
For solveing the technical problem, the technical scheme that the utility model proposes is: cancellation self-clinching standoff connected mode is provided with at least one studs between led module and casing.With screw with led module in the past direction and studs fix, with screw with casing from the rear to fixing with studs.Both can be when making maintenance from the front, demolition and maintenance led module from behind again.Specifically: a kind of led module heat abstractor comprises the casing that takes up led module; The led module that constitutes by the heating panel that laminates successively, heat conduction film, pcb board, face shield; Be provided with at least one studs between casing and heating panel, this studs two is provided with screwed hole; On heating panel, heat conduction film, pcb board, the corresponding position of face shield, have the through hole that passes through for screw.
It is cylinder that described studs leans on one of casing, and leaning on one of heating panel is the polygon cylinder, and the height of this polygon cylinder is slightly less than the thickness of heating panel; Through hole on the described heating panel is the polygon through hole that matches with described polygon cylinder body shape, so that the polygon cylinder inserts wherein.
Described polygon cylinder is cubic cylinder, and described polygon through hole is cubic through hole.
Described heating panel is provided with to vertically extending two reference columns in both sides at least, and one of this reference column is inserted in the described casing, and the other end is inserted in the described pcb board.
Described heating panel is a heat-dissipating aluminium plate.
Through hole on the described face shield is a counter sink.
The disclosed led module heat abstractor of the utility model both can be from the demolition and maintenance of casing back, also can be from the demolition and maintenance of casing front, make the maintenance work simple and fast that becomes.Simultaneously easy to process, technology is simple, effectively enhances productivity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
Fig. 1 is the heating panel of the utility model preferred embodiment;
Fig. 2 is the exploded perspective view of the utility model preferred embodiment;
Fig. 3 is the back attaching/detaching schematic diagram of the utility model preferred embodiment;
Fig. 4 is the front attaching/detaching schematic diagram of the utility model preferred embodiment.
Embodiment
Fig. 1 to Fig. 4 shows the utility model preferred embodiment, and as can be seen from Figure 2 the led module heat abstractor comprises the casing 1 that takes up led module; The led module 8 that constitutes by the heating panel 4 that laminates successively, heat conduction film, pcb board 5, face shield 7; Be provided with at least one studs 3 between casing and heating panel, this studs two is provided with screwed hole; On heating panel 4, heat conduction film, pcb board 5, face shield 7 corresponding positions, have the through hole that passes through for screw.It is cylinder that studs leans on one of casing, and leaning on one of heating panel is cubic cylinder, and the height of cubic cylinder is slightly less than the thickness of heating panel, and the through hole on the heating panel is cubic through hole, and the cubic cylinder of studs can insert wherein.Work as rotation screw, can prevent when fastening casing or led module that studs from following rotation, improve fastening efficient.
As can be seen from Figure 1 heating panel is provided with to vertically extending two reference columns 9 in both sides at least, and 9 one of reference columns are inserted in the described casing, and the other end is inserted in the described pcb board.Play the location, the effect of being convenient to install.
Heating panel in the preferred embodiment is a heat-dissipating aluminium plate.
Through hole on the face shield is a counter sink.Use countersunk head screw 6 when mounted, make the face shield surfacing.During installation with countersunk head screw 6 with led module in the past direction and studs fix, with fixed screw 2 with casing from the rear to fixing with studs.
What Fig. 3 showed is back attaching/detaching schematic diagram, when the rear portion of erecting bed has living space, in the time of can changing module at the casing rear portion, dismantles fixed screw behind casing, and the LED studs partly fastens on the whole module of LED.
What Fig. 4 showed is front attaching/detaching schematic diagram, when the rear portion of erecting bed does not have the space, in the time of can't changing module from the casing rear portion, can dismantle the countersunk head screw on the LED face shield.The LED studs then fastens on casing.Parts such as heat-dissipating aluminium plate, pcb board, face shield just can unload from the front of casing, to obtain replacing and maintenance.
Better embodiment of the present utility model has more than been described, but the those of skill in the art in the present technique field are to be understood that, these only illustrate, and can make numerous variations or modification to these execution modes, and not deviate from principle of the present utility model and essence.All fall within the scope of the utility model protection.
