LED lamp with long irradiation distance

Abstract

The invention discloses an LED lamp with long irradiation distance. The LED lamp with long irradiation distance comprises an LED lamp tube and a shell, wherein the shell is provided with an installation hole; the LED lamp tube is positioned in the shell and is connected with one end of the shell. The LED lamp with long irradiation distance is characterized in that the inner wall of the shell is provided with a semi-spherical light reflection cup; the inner wall, far away from one end of the LED lamp tube, of the shell is provided with a circular light reflection sheet. The applied lamp has long irradiation distance.

Description

technical field

[0001] The invention relates to the field of lighting devices, in particular to an LED lamp with long irradiation distance. Background technique

[0002] Light-emitting diodes, referred to as LEDs, can convert electrical energy into light energy. LED is called the fourth-generation light source. LED lighting technology has made great progress. The improvement of epitaxial technology has greatly reduced the cost of LED chips. LED has inherent excellent qualities, such as high luminous efficiency and brightness. As a new type of high-efficiency solid light source, LED lamps are the most promising green lighting source in the 21st century. LED lighting sources have been widely used in landscape lighting, street lighting, large-screen display, backlight and other fields.

[0003] At present, most of the high-power LED lamps are wide, and the light is distributed in the form of a single reflector, and the LED bulb is set at the bottom of the reflector. Part of ...
