Abstract
An electronic circuit is equipped with a lid-shaped heat sink made from aluminum sheet. Components are held in contact with the wall of the heat sink by means of lugs connected to the heat sink. The lugs are formed by bending U-shaped parts of the aluminum sheet out of the plane of the aluminum sheet.
Claims9
An electric circuit comprising
- a printed circuit board,
- a component provided on the printed circuit board,
- a heat sink secured to the printed circuit board and provided with a wall, which is in thermal contact with the component, and with a lug for pressing the component against the wall of the heat sink,
- characterized in that the lug is formed by moving a part of the heat sink with respect to the remaining part of the heat sink in such a manner that an opening adjoining the lug is formed in the heat sink.
An electric circuit as claimed in any one of the preceding claims, wherein the lug is U-shaped.
An electric circuit as claimed in any one of the preceding claims, wherein a wedge is arranged between the component and the lug.
An electric circuit as claimed in any one of the preceding claims, wherein the heat sink is made of a metal, preferably aluminum.
An electric circuit as claimed in any one of the preceding claims, wherein the electric circuit comprises a number of components and an equal number of lugs, each component being in thermal contact with the wall of the heat sink, and each component being pressed against the wall of the heat sink by a lug, and each lug being formed by moving a part of the heat sink with respect to the remaining part of the heat sink in such a way that an opening is formed in the heat sink, which opening adjoins the lug and the surface area of which is equal to that of the lug.
An electric circuit as claimed in any one of the preceding claims, wherein the electric circuit comprises an electronic ballast for energizing a lamp.
