The invention provides an LED (Light-emitting Diode) surface-mounted down lamp, wherein the tail cover is arranged at one end of the hollow shell in a covering mode, the radiator is installed in the hollow shell, the light-emitting mechanism is installed on the radiator, and the light guide ball and the reflecting cover are sequentially arranged on the light-emitting mechanism in a covering mode.The radiator is a radiating disc; cooling fins are arranged at the bottom of the cooling disc. The light-emitting mechanism is arranged in the middle of the upper end face of the heat dissipation disc. An annular boss is arranged on the inner side wall of the hollow shell, the radiator is connected to the annular boss in a clamped mode and fixed in the hollow shell through screws, a plurality of ventilation sets are evenly distributed on the peripheral wall of the tail cover, each ventilation set is symmetrically arranged along the center axis of the tail cover, and each ventilation set comprises a plurality of ventilation holes. The ventilation set can achieve convection, the gas flowing efficiency in the lamp body is improved, the heat dissipation efficiency is improved, and the servicelife of the lamp is prolonged.
Description
technical field [0001] The invention relates to a lighting tool, in particular to an LED surface-mounted downlight. Background technique [0002] LED surface-mounted downlight is a lighting fixture embedded in the ceiling or wall, which can increase the soft atmosphere of the space, create a warm feeling, and reduce the pressure of the space. In order to improve the beauty and safety, some radiators are located inside the lamp body. Since the LED lamp will generate a large amount of heat during operation, if the cooling effect of the cooling device is poor, it will affect the performance of the downlight and shorten the service life of the downlight. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficiencies in the prior art, and provide an LED surface-mounted downlight with good heat dissipation e...
