Round radiator for LED courtyard lamp

Abstract

The invention discloses a round radiator for an LED courtyard lamp. The round radiator comprises a round radiator body, a groove-shaped light-reflection cup, a basin-shaped light-reflection cup, a power box, an LED driver board, an LED aluminum substrate, a plug and a connecting frame and is characterized in that fork-shaped rib pieces and fins are arranged on and around the groove-shaped light-reflection cup of the round radiator, the outer sides of the fork-shaped rib pieces and fins are connected with an annular heat-dissipation band and form a ventilation opening, a convex rib piece arranged at the center of the groove-shaped light-reflection cup and the plug are fixed through bolts, and an air inlet-outlet hole is formed in the center of the plug. The round radiator has the advantages that the fork-shaped rib pieces and fins are directly connected to the annular heat-dissipation band, and the heat radiation and dissipation effect is improved. An air inlet is formed in the plug, so that air convection for heat dissipation of the round radiator is promoted, and the 'heat island effect' of the center of the high-power lamp is eliminated. Various sensors, such as a sound-sensitive sensor, a photo-sensitive sensor, an infrared sensor and an optical-communication sensor, can be arranged on the plug. The round radiator is suitable for ceiling lamps, plant lamps, industrial mining lamps, suspended lamps and other courtyard lamps assembled in indoor tall and big space and used for general illumination, and intelligent illumination lamps can be achieved.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to a circular radiator for an LED patio light. Background technique [0002] In recent years, under the background of rising concerns about global energy shortage, energy conservation is an important issue we face. LED lamps have entered the interior from the outside, from landscape lighting, road lighting, to interior decoration lighting of civil buildings, commercial lighting and industrial lighting. The application of LED lighting products is attracting the attention of the world, and the scope of application is getting wider and wider. As a new type of green lighting product, LED is the future development trend. [0003] LED lighting fixtures in the prior art have a big heat dissipation problem. LED has high requirements on heat dissipation technology. When the heat sink is not effective, the temperature of the LED light chip will rise sharply, which will quic...

AI Technical Summary

Problems solved by technology

[0004] The driving power of the existing LED lamps is installed in the radiator, and the heat insulation structural measures are not taken, which causes the heat of the LED driving power itself to increase, and the service life of the power is reduced.

At the same time, the heat of the driving power affects the increase of the temperature rise of the radiator, resulting in high temperature of the LED and serious light decay.
