Abstract
A LED lamp radiating structure for efficient transmission, on a heat dissipation base plate, a light source support is connected with a fixed loop order, Radiating substrate through which two or more than two connecting lugs and a light source bracket trapezoidal plug-in connection, the connection bumps into trapezoidal barb structure or inverted card structure, the fixing ring is sleeved on the outer edge of the light source bracket, and the heat dissipation baseplate is connected. The utility model increases the biography area of dissipation, and it is more even to pass the heat dissipation, has ensured to pass radiating quality and quantity, has effectively solved the problem that both expand with heat and contract with cold and exist, has effectively avoided lamps and lanterns to pass the influence that heat dissipation mechanism does not receive any environment or external force factor, makes lamps and lanterns under any circumstance work and can both reach all-round protection, with the normal life-span of guaranteeing that lamps and lanterns use.
Description
Technical field
The utility model relates to the radiator structure of light fixture, refer to especially a kind of by guaranteeing thermal balance and increase to pass area of dissipation, with the structure of the purpose of the high efficiency and heat radiation that reaches the LED light fixture.
Background technology
At present, though generally the LED light fixture of Shi Yonging is energy-efficient, all exist owing to the radiating effect difference causes the problem that shortens its service life.The biography cooling mechanism of existing light fixture mostly is: pass radiating surface and be the plane, allow heat abstractor and led light source connect into the biography radiator structure by screw locking or bonding way, the flatness of the biography radiating surface of this class formation is difficult to guarantee, to such an extent as to the uniformity that influence heat is transmitted is inconsistent; The biography area of dissipation is not enough, to such an extent as to heat conduction amount is not good enough, thereby influences radiating effect; The temperature difference under light fixture work and the off working state up to 100 ° about, cause the phenomenon that the light fixture all material all can be expanded with heat and contract with cold and influence normal performance of light source and duty, to such an extent as to occur that the light source gold thread is broken, light source surface silica gel gets loose, passes great number of issues such as heat radiation contact-making surface minimizing; Have a strong impact on the normal biography heat sinking function of light fixture; The bulk life time of light fixture shortens.
Summary of the invention
For addressing the above problem, the utility model provides a kind of assurance thermal balance and increases contact area, realizes the efficient heat radiation that passes, with the biography radiator structure of the LED light fixture that guarantees light fixture normal service life.
For achieving the above object, the technical solution adopted in the utility model is: on heat-radiating substrate, light source bracket and retainer ring are linked in sequence, described heat-radiating substrate is connected with trapezoidal plug-in unit on the light source bracket by two or more the connection projection on it, this connection projection is the card structure that falls of trapezoidal overhead structure or other shapes, described Fixing shrink ring is connected to the light source bracket outer rim, and is connected in heat-radiating substrate.
The connection projection of described heat-radiating substrate is regular distribution thereon, and this connects the projection space and forms draw-in groove, and the distribution area that connects projection matches with the contact area of light source bracket, and there is threading via hole at the center of heat-radiating substrate.
The trapezoidal plug-in unit of described light source bracket is distributed in the relevant position of heat-radiating substrate draw-in groove, leaves connecting groove in the middle of light source bracket.
The described retainer ring side that is connected with heat-radiating substrate has protruding pin, and it is plugged on the locating hole of heat-radiating substrate by this protruding pin.
The beneficial effects of the utility model are: connect the intercalation design between projection and trapezoidal plug-in unit, and connection projection distribution area matches with the contact area of light source bracket, make heat-radiating substrate and light source bracket fit tightly, guarantee the balance that hot biography is loose and increased the biography area of dissipation, it is more even to pass heat radiation, ensure the quality and quantity that passes heat radiation, efficiently solved the problem that both expand with heat and contract with cold and exist; In light source bracket outer rim socket retainer ring; effectively avoided light fixture to pass the influence that cooling mechanism is not subjected to any environment or external force factor; the biography thermal diffusivity of retainer ring itself in addition; realized the efficient biography heat radiation of this structure; light fixture is under any circumstance worked to reach omnibearing protection, with the ordinary life that guarantees that light fixture uses.
