Abstract
The invention discloses a straight tube type chimney effect bulb lamp with a function of improving thermal convection. A plurality of hollow straight-tube-shaped chimney channels which is punched through in the up-down direction are formed in a radiator, and surround a base plate, heat generated by an LED light source module during working is transferred to the base plate at first, and then is transferred to the radiator from the base plate, cold air enters from a chimney channel inlet in the bottom of the radiator, takes away heat on the radiator along the chimney channels, continues moving upwards and is discharged from a chimney channel outlet in the top of the radiator, new cold air continues entering from a chimney channel inlet in the front side of the radiator so as to improve mobility of air surrounding the LED lamp, and smooth, quick and natural thermal convection is implemented. By the straight tube type chimney effect bulb lamp with the function of improving the thermal convection, the problem that air in a lamp body with a common chimney structure flows to generate eddy so that air circulation rate is reduced is avoided. Therefore, the straight tube type chimney effect bulb lamp has the advantages of good heat dissipation effect, simple and reasonable structure and high practicality.
