Problems solved by technology

Of course, like all other LED lamps, the heat dissipation problem of LED chandeliers is also a key issue. The heat dissipation problem seriously affects the light efficiency and life of the LED light source. Many LED lamps now do not make full use of the effective area and the convection condition is not ideal. The temperature of the light source and power supply is too high, which affects the light efficiency and life of the LED, and also seriously affects the life of the power supply

Abstract

The invention relates to a light-emitting diode (LED) pendant lamp. The LED pendant lamp comprises LED components, a lamp cap part and a lamp cup, wherein the lamp cap part has an effect of heat dissipation; the LED components are arranged on the lamp cap part; the lamp cup is clamped with the lamp cap part; the upper opening of the lamp cup is provided with an annular shielding surface; the center hole of the annular shielding surface is fitted with the lower edge of the LED components to shield the LED components in the lamp cap; the annular shielding surface is provided with air vents; and the upper part of the lamp cap part is also provided with air vents, and the air vents and the air vents formed in the annular shielding surface form air convection up and down. According to the LED pendant lamp, the conventional die-casting shell having a heat conduction effect on a cover body of the pendant lamp is used for transverse thermal radiation, the upper side of the cover body and a joint between the lamp cup and the LED components are provided with the air vents, and the LED components integrated with power sources and light sources can form air convection in a vertical direction and can effectively dissipate heat, so that the service life of LED light sources is prolonged, and the luminous efficacy of the whole pendant lamp is improved.

Description

technical field [0001] The invention relates to a chandelier, in particular to an LED chandelier. Background technique [0002] LED light sources have the advantages of high light efficiency and environmental protection. Therefore, LED light sources are used in almost all types of lighting fixtures, such as chandeliers for home lighting. General household chandeliers have dual functions of decoration and lighting. LED chandeliers are energy-saving and have a long life, avoiding the trouble of often needing to replace bulbs, and are favored by more and more users. Of course, like all other LED lamps, the heat dissipation problem of LED chandeliers is also a key issue. The heat dissipation problem seriously affects the light efficiency and life of the LED light source. Many LED lamps now do not make full use of the effective area and the convection condition is not ideal. The temperature of the light source and power supply is too high, which affects the light efficiency and ...
