Abstract

The invention discloses an LED lamp which can be used for the commercial illumination of offices, markets, subways, libraries, banks, hotels, and the like. The LED lamp comprises a hollow heat radiator (1) and a reflecting cup (2) which is adapted to an inner cavity of the heat radiator, wherein the bottom of the reflecting cup (2) is provided with a through hole (5); the bottom of the inner cavity of the heat radiator (1) is provided with a control circuit board (8); at least one LED light source (7) is arranged on the control circuit board; and the LED light source is positioned in the through hole (5) of the reflecting cup (2). According to the invention, as the LED light source for generating a heat source is directly connected with the heat radiator, the heat transfer path is shortened and the heat conduction efficiency is greatly improved, so that the temperature of the lamp is rapidly reduced to delay the light attenuation and prolong the service life.

Description

technical field [0001] The invention relates to lighting fixtures, in particular to an LED reflector lamp which can be used for commercial lighting in offices, shopping malls, subways, libraries, banks, hotels and the like. Background technique [0002] Due to the outstanding advantages of LED (Light Emitting Diode, light emitting diode), such as energy saving, environmental protection, long life, simple structure, and convenient shape, it has gradually replaced traditional high-voltage halogen lamps and is widely used in various lighting equipment. In actual production, one or several LEDs are installed on the light source panel located in the lamp housing as the light source to achieve the required brightness and power. The light emitted by the LED is refracted by the reflector set in the lamp housing and then projected out. The more LEDs you set, the brighter and more powerful your lamps will be. [0003] However, LED lamps generate a lot of heat when they work, and the ...
