Embodiment Construction

[0016] Depend on Figure 1 ~ Figure 2 As shown, the present invention includes a ring-shaped lamp housing 1, a lampshade 4, a power controller 7 and a group of high-power LED3, and the high-power LED3 is fixed on a side plane of the ring-shaped lamp housing 1, and is surrounded by the lampshade 4 to form a ring type light source. The high-power LED 3 is electrically connected with the power controller 7 . The shape of the ring-shaped lamp housing 1 can also be selected from various specifications such as square shape and rectangular shape, so as to meet the requirements of different powers and different lighting angles required by different venues. The ring-shaped lamp housing and heat sink are made of aluminum with good thermal conductivity.

[0017] The packaging shape of high-power LED3 is generally square, polygonal, and long-strip. In square and rectangular lamp housings, long-strip high-power LED3 or long-strip and other shapes of high-power LED3 can be used in combina...

Abstract

A high power LED ceiling lamp for ordinary illumination comprises a circular lamp housing, a lampshade, a power controller and a group of high power LEDs, wherein the LEDS are fixed on one side of the circular lamp housing and surrounded by the lampshade to form a circular light source; a radiating fin is fixed on the back of the circular lamp housing equipped with the high power LED, a plurality of radiating holes are arranged around the outside of the circular lamp housing, and blowholes are positioned around the inside of the housing; the power controller and a sensor are arranged inside the housing of the power source , and the housing of the power source is fixed on the inner ring center of the circular lamp housing, and isolated from the inner ring with air to prevent the heat of the circular lamp housing from heating up the electrolytic capacitor in the power controller, thus the service life of the controller can be prolonged. The circular lamp housing and the radiating fin of the invention both adopt aluminum material with favorable thermal conduction property, and can employ a plurality of manufacturing processes such as pressing, die-casting, extrusion and the like, thus the structure is compact, the cost is lowered, and can meet the requirements of the high power semiconductor lighting luminaire such as ceiling lamp, sunken light, hanging light, etc.

Description

technical field [0001] The invention relates to a semiconductor lighting fixture, in particular to a high-power LED ceiling lamp which isolates a power supply controller from the inner side of a ring-shaped lamp shell with air. Background technique [0002] Semiconductor electric light source is a kind of electric light source without filament. It is a light-emitting device that directly converts electrical energy into light energy. It is called a light-emitting diode, also known as a semiconductor lamp, and is referred to as LED in English. Semiconductor lighting is considered to be a new energy-saving light source for lighting in the 21st century. LED not only saves energy, but also has the characteristics of long life, small size, safety, environmental protection, maintenance-free, and easy control. LEDs can already replace traditional light sources in many places, especially the emergence of high-power LEDs, which has accelerated the speed at which LEDs replace traditio...
