Abstract

The invention discloses a vertical convector radiator and comprises a vertical convector radiating down lamp of the vertical convector radiator. The vertical convector radiator comprises light source installation parts and a plurality of heat radiating fins of which the lower ends are connected with the light source installation parts in a heat conducting mode, wherein the vertical convector radiator comprises a plurality of convection passageways which penetrates through and is vertical to the upper surface and the lower surface of the convector radiator. When the vertical convector radiator in the technical scheme adopted operates, the lower end of the heat dissipation rectangular fin continuously heats the neighbouring air and the air rises, simultaneously, the neighbouring cold air can continuously complement to generate convection, thus the vertical convector radiator of the specific implement method can form a higher air velocity field even under the passive voice radiating condition, full heat exchange is generated between the cold air and the heat dissipation rectangular fin surface of the vertical convector radiator, the heat is rapidly take away, thereby avoiding the generation of the heat island effect in the bottom of the radiator, and the heat dissipation capacity is greatly improved.

Description

Technical field

[0001] The invention relates to the technical field of lighting and heat dissipation, in particular to a vertical convection radiator and a vertical convection radiating downlight with the radiator. Background technique

[0002] In recent years, the technology of LED lighting has developed rapidly, and high-power LED lighting has entered the application stage, but the heat dissipation problem has always been one of the core problems of high-power LED lighting to be resolved.

[0003] As far as the light efficiency level of existing LEDs is concerned, 70% to 80% of the input electric energy will be converted into heat. Moreover, due to the small size of the LED chip, poor heat dissipation will cause the temperature of the LED chip to rise sharply, causing problems such as uneven thermal stress distribution, reduced chip luminous efficiency, and reduced phosphor lasing efficiency. In addition, poor heat dissipation will result in a higher temperature rise of the chip...
