Abstract
The utility model discloses an LED driving device, and aims to provide an LED driving device with small volume, favorable protectiveness and high heat dissipation. The LED driving device provided by the utility model comprises an external box and a circuit board mounted therein; a metallic drawer-type panel, a cover plate and a lateral panel are fixedly mounted to form the external box; a through hole capable of accommodating a transformer is formed in the middle of the circuit board; and black glue is filled between the circuit board and the external box, thus the circuit board and the external box are completely sealed to form a whole.
Description
Technical field:
The utility model relates to a kind of LED drive unit, particularly relates to the LED drive unit that a kind of volume is little, protectiveness good, thermal diffusivity is high.
Background technology:
Near harshness, LED can directly connect the electric main of 220V unlike common incandescent lamp bulb to the LED device to the requirement of driving power, and LED is 2～3 volts a low voltage drive, must design a voltage conversion circuit.The luminous efficiency of LED can descend along with the rising of LED temperature, so the heat radiation of LED is extremely important.
Transformer in the present LED drive unit on the market is directly installed on the circuit board, and occupation space is bigger, causes the thickness of whole LED drive unit to increase greatly; The outer box of LED drive unit generally adopts plastic material, though whole device is become lightly, can also reduce the cost, and the protectiveness of drive unit is bad, and outer box is easy to damage, thereby causes the circuit board of outer box the inside impaired; The circuit board of LED drive unit the inside generally is to be fixed in the outer box through screw, though simple to operate, save material, thermal diffusivity is bad, makes the luminous efficiency of LED descend along with the rising of temperature.Up to the present, also there is not the LED drive unit that a kind of protectiveness is good, thermal diffusivity is high and outer box is thin on the market.
The utility model content:
The purpose of the utility model is to overcome the deficiency of prior art, and the LED that a kind of protectiveness is good, thermal diffusivity is high and volume is little is provided drive unit.
In order to solve the technical problem of above-mentioned existence; The utility model adopts following technical proposals: the utility model LED drive unit comprises outer box and the circuit board that is installed in the outer box, and described outer box is made up of through the screw fixed installation drawer type panel, cover plate and the side panel of metal material; Offer the through hole that to place transformer in the middle of the described circuit board.
Furthermore, in the technique scheme, irritating between said circuit board and the outer box has black glue, and circuit board and outer box are sealed fully, forms an integral body.
Furthermore, in the technique scheme, described drawer type panel cooperates assembling to constitute by left panel, right panel, middle panel and base plate.
Furthermore, in the technique scheme, said left/right panel upper end all is provided with high outside and low outside half groove that is stairstepping, and wherein, the degree of depth of half groove and the thickness of cover plate are consistent.
Furthermore, in the technique scheme, described cover plate and half groove part corresponding with it are respectively arranged with supporting side screw hole; Side panel and half groove part corresponding with it are respectively arranged with the supporting hole of tightening up a screw.
Furthermore, in the technique scheme, it is characterized in that described side panel and middle panel are offered circular left and right wire guide respectively.
The utility model LED drive unit has following beneficial effect compared with prior art:
1, the circuit board in the utility model LED drive unit is provided with through hole, and components and parts are installed in the through hole, greatly reduces the thickness of outer box, thereby makes whole device become thinner, and volume is littler.
2, protectiveness is good: the utility model adopts the outer box of metal, can protect outer box well; Outer box contacts through pouring into black glue with the circuit board of the inside fully, forms an integral body, circuit board is completely fixed the box the inside outside, so that the better protection circuit board.
3, thermal diffusivity is good: because black glue thermal conductivity is strong; To deceive glue and pour between outer box and the circuit board, circuit board and outer box are sealed fully, both form an integral body; The heat that components and parts produce can directly be transferred to the outer box of metal through black glue, and the components and parts on the circuit board can be dispelled the heat soon.

Embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
Among Fig. 1, the utility model LED drive unit comprises outer box 1 and the circuit board 2 that is installed in the outer box 1, and the drawer type panel 11 of metal material, cover plate 12 and side panel 13 constitute outer box 1 through the screw fixed installation; Circuit board 2 is installed in the outer box 1, will deceive glue and pour between circuit board 2 and the outer box 1, and circuit board 2 and outer box 1 are sealed fully, and both form an integral body, so that can better protection circuit board 2; Because black glue thermal conductivity is strong, the heat that components and parts produce can directly be transferred to the outer box 1 of metal through black glue, and the components and parts on the circuit board 2 can be dispelled the heat soon.
Among Fig. 2; Circuit board 2 is tabula rasas of not placing any components and parts, and mid portion has been offered a through hole 21 that is slightly larger than transformer 6 sizes, and this through hole 21 is used to place transformer 6; Circuit board 2 is stuck in the middle of the transformer 6; Thereby reduced the thickness of transformer 6 on circuit board 2 greatly, made that the whole LED drive unit is thinner, volume is littler.
Among Fig. 3, left panel 111, right panel 112 upper ends all are to be arranged to high outside and low outside half groove 3 that is stairstepping, and the degree of depth of this half groove 3 equates with the thickness of cover plate 12, not only be convenient to be placed on cover plate 12 on half groove 3, and joining place is smooth.Side panel 13 and middle panel 113 are offered the left wire guide 71 and right wire guide 72 of a circle respectively, so that external wire.
Certainly; The above is merely an embodiment of the utility model; Be not to limit the utility model practical range; Everyly utilize the through hole offered in the circuit board to place components and parts to reduce whole device thickness, box is inner outside fills black glue or other glue all belongs to the novel scope of this experiment with the LED drive unit of doing thermolysis and protective effect.
