The invention has the beneficial effect that influence on other components in the ballast by heat emitted by the heating components is minimized.
Description
Technical field
The present invention relates to a kind of structure of electric ballast.
Background technology
Now electric ballast is little with its volume, and the efficiency height become the favorite of energy-saving field, but heat dissipation problem is one of its technological difficulties;
In HID lamp when work, produce a large amount of heats, causes temperature in the light fixture about 60 degree, and electric ballast is installed under the environment of high temperature like this, and heat radiation becomes technological difficulties, the characteristic of the electrochemical capacitor of electric ballast inside be temperature more the high life short more;
The rectifier bridge of electric ballast inside, high-power MOS tube (or triode), switching diode etc. all are the bigger components and parts of caloric value, if the untimely above original paper heat radiation or the bad words of dispelling the heat of giving, to be difficult to guarantee each original paper long-term stable operation, also just can not guarantee the resistance to overturning of ballast.
Summary of the invention
The structure that the purpose of this invention is to provide a kind of electric ballast.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of structure of electric ballast, it is characterized in that: the little components and parts of caloric value are assemblied in the top of wiring board, the components and parts that caloric value is bigger are mounted on the bottom of wiring board, the wiring board that assembles is inverted the inner face of the upper sectional material that is assemblied in the ballast shell, the components and parts that caloric value is bigger fit tightly the inner face at the upper sectional material of ballast shell, refill the lower sectional material of joining the ballast shell, it is as a whole that the last lower sectional material of ballast shell relies on ballast shell left plate to be connected with ballast shell right plate, and the ballast installing hole has on the left side plate of ballast shell.
Described ballast shell is mainly by two blocks of aluminium section bars and two blocks of " L " shape side plates are formed up and down; The ballast mounting hole site that is positioned at the ballast bottom is arranged on the minor face of " L " shape side plate.
The upper sectional material thickness of described ballast shell is installed the heat radiation grid greater than the lower sectional material of ballast shell in the top and the both sides of ballast.
The invention has the beneficial effects as follows:
1, heater members is placed between the inner plane and wiring board of upper sectional material (1), the heat of heater members can more directly be conducted and because the buffer action of circuit, make heat that heater members sends out to other components and parts of ballast inside influence drop to minimum.
2, because that the heat radiation grid of ballast top section bar can be done is darker, radiating surface is bigger; Secondly because the top air flow property is better, so utilize ballast upper sectional material (1) the radiator effect of deciding better.
3, because heat transmits in the ballast inner space characteristic of come-up is arranged, thus pyrotoxin is placed the ballast top, less to the thermal impact of ballast internal components.
4, because the shell of ballast all adopts the aluminium alloy manufacturing, so effectiveness is better.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1: be the electric ballast outside drawing;
Fig. 2: the end view drawing of aluminium section bar up and down that is the electronic ballast shell;
Fig. 3: be the circuit board structure schematic diagram;
Fig. 4: the assembling schematic diagram that is wiring board and aluminium section bar shell.
Among the figure: 1. the upper sectional material of ballast shell, 2. lower sectional material, 3. ballast shell left plate, 4. ballast shell right plate, 5. little components and parts of most of caloric value on the ballast circuit plate, 6. wiring board, components and parts that 7. the fraction caloric value is bigger on the ballast circuit plate, the 8. ballast installing hole of ballast shell.
Embodiment
Most preferred embodiment:
1, the shell of electric ballast:
Shell is by the upper sectional material 1 of ballast shell, the lower sectional material 2 of ballast shell, ballast shell left plate 3 and 4 four main parts of ballast shell right plate, and auxilliary materials such as waterproof terminal and ground wire terminal, sealing gasket, screw are formed.
Three faces of the last lower sectional material of ballast shell except that the installed surface of ballast bottom all increase radiating surface by the heat radiation grid, and upper sectional material is as main heat sink section bar, so thickness is thicker; So lower sectional material is considered the product cost factor thinner thickness because of non-main heat sink section bar.
2, the main circuit board of electric ballast:
The less original papers of caloric value such as electric capacity, resistance, diode are installed in the top layer of wiring board.The bigger components and parts of caloric value such as high-power MOS tube (or triode), rectifier bridge, switching diode are mounted on the wiring board bottom.
The bottom of wiring board is the radiating surface benchmark with the heater members of the highest (the thickest), and highly the mode of Bu Zu employing pad insulation cushion is proofreaied and correct, make the wiring board bottom all the heating original papers radiating surface on same level height.
3, assembling:
As shown in Figure 4: the components and parts 5 that caloric value is little are assemblied in the top of wiring board 6, and the components and parts 7 that caloric value is bigger are mounted on the bottom of wiring board 6.Again the wiring board that assembles is inverted the inner face of the upper sectional material 1 that is assemblied in the ballast shell, that is: make the bigger components and parts of caloric value 7 fit tightly inner face at the upper sectional material 1 of ballast shell, refill the lower sectional material 2 of joining the ballast shell, the last lower sectional material of ballast shell, rely on ballast shell left plate 3 to be connected as a whole with ballast shell right plate 4, ballast installing hole 8 exists, and has on the left side plate of ballast shell, with installing and fixing ballast.
