Embodiment Construction
[0013] The present invention will be further elaborated below in conjunction with accompanying drawing:
[0014] Such as figure 1 , 2 Shown is an LED lighting lamp with a hollow channel radiator. The lighting lamp is composed of a lamp cap 1, a heat sink 2, and a lamp body 3 in sequence. The heat sink 2 is provided with a ring-shaped hollow cavity 21, and the hollow cavity 21 A lamp base opening 211 and a lamp body opening 212 are respectively provided on the outer side of the lamp base end and the bottom end of the lamp body end.
[0015] The heat sink 2 gradually increases in size toward the lamp body 3, the lamp body opening 212 is a ring-shaped fully open opening, and the lamp cap opening 211 is a long strip opening evenly distributed around the circle, so that the gas flow channel in the flow direction from The channel from the hollow cavity 21 to the lamp cap opening 211 and then to the outside first shrinks and then expands to form a Rafal nozzle effect and accelerate...

The invention relates to the technical field of lighting lamps, in particular to a light-emitting diode lighting lamp with a hollowed-out channel heat radiator. The lighting lamp disclosed by the invention comprises a heat-radiating seat which is provided with an annular hollowed-out cavity, wherein a lamp holder opening and a lamp body opening are respectively arranged at the outer side of a lamp holder end of the cavity and at a bottom end of a lamp body end of the cavity; during installation, the light-emitting diode lighting lamp is generally installed vertically, when a lamp body works, the heat of the lamp body is transmitted to the heat-radiating seat, air in the cavity is about to flow upwards under a heated condition and flows out upwards from the lamp holder opening of the lamp holder end, cold air is introduced in from the lamp body opening for compensation, thus, the lamp holder opening, the cavity and the lamp body opening constitute a circulating air flow channel so as to generate a chimney effect and form intense convection heat radiation for the heat-radiating seat; and the heat-radiating seat can be used for radiating heat in transmission, convection and radiation manners and has a good heat-radiating effect, so that the heat generated by the lamp body of the light-emitting diode lighting lamp is timely transmitted away and dispersed, the normal operation of the light-emitting diode lighting lamp is ensured, and the service life of the light-emitting diode lighting lamp is prolonged.
Description
technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to LED lighting lamps with hollow channel heat sinks. Background technique [0002] Lighting lamps, especially light-emitting diode lighting (LED lights), need heat dissipation treatment. A common light-emitting diode lighting lamp is composed of a lamp cap, a heat sink, and a lamp body in sequence; the lamp body is the source of heat, and the heat conduction heat sink of the lamp body On the top, the heat is conducted through the heat sink to ensure the normal operation of the LED lighting. Usually, the heat sink is solid and conducts heat with the working environment. The heat conduction is carried out by transfer, convection, and radiation. Generally, the ambient air flow in the space where the LED lighting lamp works is small, and the most important heat conduction of the heat sink is transfer and radiation. Mainly; but when the heat sink transfers heat to the air, th...
