Abstract

The invention relates to an LED lamp with the convection heat dissipation function. The LED lamp comprises a metal tray and a lampshade. The top of the metal tray is sleeved with the lampshade, and the lampshade and the metal tray are sealed. The metal tray in the lampshade is sequentially provided with a lamp holder bridge type support, a ceramic lamp holder and an LED lamp from bottom to top. An LED lamp lower end air inlet is formed between the LED lamp and the ceramic lamp holder. A convection heat dissipater is movably arranged on the periphery of the LED lamp lower end air inlet. The convection heat dissipater is of a tubular structure with a downward opening, and the lower opening of the convection heat dissipater is located above the metal tray. A chimney-shaped heat tube is formed by the convection heat dissipater, the LED lamp lower end air inlet and an LED lamp inner cavity jointly. Independent dependence on metal conduction heat dissipation is avoided, heat dissipation is achieved by fully using air convection and the heat dissipation capacity of an existing material in the lamp, heat dissipation is reliable, a method is scientific, and implementation is convenient. The heat dissipation capacity can be greatly improved by additionally arranging the convection heat dissipater. Due to the fact that the existing material is adopted for heat dissipation, compared with an existing LED heat dissipater, consumed materials are greatly reduced, and cost is low.

Description

technical field [0001] The invention belongs to the field of lamps and relates to a street lamp, in particular to an LED lamp with a convection heat dissipation function. Background technique [0002] The heat dissipation problem of enclosed lamps has always restricted the application of high-power LED light sources in the field of street lamps. Existing radiators use metal conduction to transmit heat out of lamps, and metal conduction radiators are expensive and expensive. [0003] In order to dissipate heat from the lamps, the existing radiators for high-power LED lamps are designed integrally with the LED lamp and the tray, and metal heat-conducting materials are connected from the LED lamp to the outer bracket of the tray to dissipate heat by conduction. The heat dissipation capacity of this type of radiator is closely related to the cross-sectional size of the metal heat conductor. In order to achieve the heat dissipation effect, a large amount of metal materials must b...
