LED (light emitting diode) down lamp

Abstract

The invention discloses an LED (light emitting diode) down lamp, and relates to the field of lamps. The invention aims at providing the LED down lamp which is simple in structure, low in cost, simpleand convenient to operate. The LED down lamp comprises a heat dissipation component, a lampshade and a light control module, wherein the heat dissipation component comprises a heat dissipation barrel,a heat dissipation plate and a heat dissipation driving module; a connecting shaft is arranged on the heat dissipation driving module; the heat dissipation barrel and the heat dissipation plate are fixedly arranged on the connecting shaft; the connecting shaft is rotatably connected to the lampshade; and the lampshade, the light control module and the heat dissipation driving module are fixedly arranged.

Description

technical field [0001] The invention relates to the field of lamps, in particular to an LED downlight. Background technique [0002] LED downlight is a kind of downlight lighting fixture embedded in the ceiling. LED downlight is a directional lighting fixture, only its opposite side can receive light, the beam angle belongs to spotlight, the light is concentrated, and the contrast between light and dark is strong. [0003] In the existing downlights, the heat sinks connected to the lamp body are mostly ring-shaped internal and external closed structures, and the heat dissipation effect of the lamp body is poor, and the heat and air convection exchange effect is poor. Because the heat in the center is large and concentrated, the heat dissipation is often not timely. , the instantaneous temperature will exceed the upper temperature limit of the LED, which will cause the LED to fail. It is troublesome to replace the bulb of the downlight. Generally, the whole lamp is scrapped...

Problems solved by technology

[0003] In the existing downlights, the heat sinks connected to the lamp body are mostly ring-shaped internal and external closed structures, and the heat dissipation effect of the lamp body is poor, and the heat and air convection exchange effect is poor. Because the heat in the center is large and concentrated, the heat dissipation is often not timely. , the instantaneous temperature will exceed the upper temperature limit of the LED, which will cause the LED to fail

It is troublesome to replace the bulb of the downlight. Generally, the whole lamp is scrapped directly. The scrapping of the whole lamp will waste social energy and increase the cost of consumer expenditure, which in turn affects the production and sales of downlights.
