Summary of the invention
The utility model provides a kind of LED lamp with asymmetric cooling structure, and this lamp can the thermal conductance that led chip is sent more rapidly and efficiently go out, and the heat that will derive in time is dispersed in the ambient air environment.
In order to solve the problems of the technologies described above, the utility model proposes a kind of LED lamp with asymmetric cooling structure, comprise lamp body, lamp body comprises the radiator of circuit substrate, heat-conducting plate and LED lamp; The LED lamp is located on the circuit substrate, is heat-conducting plate below the circuit substrate, and the LED lamp is provided with lens; The fan and the semiconductor cooler that also comprise heat radiation;
A side of described radiator is the plane, fixedlys connected with described fan in this side; This radiator comprises heat radiating fin, and the slit of break-through radiator two relative side is arranged between the heat radiating fin, and the slit between the heat radiating fin faces radiator fan;
Described lens are the peanut shape lens, and the LED lamp is positioned at the minor axis eccentric position of described lens;
Be provided with groove between radiator and described heat-conducting plate, groove is positioned at position under the LED lamp, and the opening of groove is in the side of described lamp body; Described semiconductor cooler places groove to be embedded between radiator and the heat-conducting plate, and the cold of semiconductor cooler extremely is connected with heat-conducting plate, and thermoae end is connected with radiator.
Preferably: described fan and semiconductor refrigerating wafer have a common power connection.Can be suitable for the 12V power supply based on them, therefore can design same power connection to them.
Preferably: the power interface that on described lamp body, is provided with described power connection.
Preferably: described LED lamp is a white light, and white light excites gold-tinted fluorescent material to send by blue chip.
Preferably: described fan and radiator are fixed by screw, are equipped with screw hole on fan and radiator.
Beneficial effect is as follows:
Compared to existing technology, the utility model is on the circuit substrate at the LED lamp and the asymmetrical position of lens, has carried out the design of optimization cooling.This design has increased a groove between radiator and heat-conducting plate, mounting semiconductor refrigerator in this groove.Because this semiconductor cooler only is provided in a side of below the led chip, its individual area is little, and is therefore cheap controlled.It can arbitrarily take out from groove and can lay according to the heat radiation needs, has good replaceability, changes more convenient.Because light fixture of the present utility model has the direction deflection, therefore can be useful on the automobile, and be useful on some light fixture that the deflection illumination is provided, as pinup.
