Embodiment Construction

[0034] like Figure 1-3 Shown is a preferred embodiment of the LED lamp 100 of the present invention. The LED lamp 100 includes a lamp housing 10 , a light-emitting module 20 disposed in the lamp housing 10 , a light-transmitting cover 30 and a fixing frame 40 .

[0035] like image 3 As shown, the cross section of the lamp housing 10 is a trapezoid, and the large end of the trapezoid section is an opening. The lamp housing 10 includes a mounting plate 11 and a side wall 12 extending obliquely from the edge of the mounting plate 11 . A bottom end forms a light exit window 15 . In this embodiment, the mounting plate 11 is a vertically long flat plate with two opposite long sides and two opposite short sides. The side wall 12 includes two side plates 120 which are respectively inclined downward and outward from the two long sides of the mounting plate 11 . The included angle between each side plate 120 and the mounting plate 11 is an obtuse angle, so that a trapezoidal rece...

Abstract

The invention relates to a light-emitting diode (LED) lamp. The lamp comprises a lamp shell and a light-emitting module, wherein the light-emitting module comprises at least one LED; the lamp shell comprises an installation plate and a side wall extending from the edge of the installation plate; an accommodating space is enclosed by the installation plate and the side wall; the light-emitting module is arranged in the accommodating space; and the end of the lamp shell, which is opposite to the installation plate, is provided with a light-emitting window. When the LED lamp works, light rays, which are positioned on the outermost side, in a light beam emitted by the LED are directly emitted outwards through the light-emitting window without being reflected by the side wall of the shell.

Description

technical field [0001] The present invention relates to a lighting device, in particular to a light-emitting diode lamp. Background technique [0002] As an efficient light source, light-emitting diodes have many advantages such as environmental protection, power saving, and long life. They have been widely used in various fields and have the potential to widely replace traditional light sources. [0003] At present, LED lamps for lighting often include a lamp housing and one or more light-emitting diodes disposed in the lamp housing. The lamp housing has a mounting plate for mounting the light emitting diodes and a side wall extending from the same edge of the mounting plate, and part of the light beams emitted by the light emitting diodes are reflected by the side wall of the lamp housing and then emitted outward. In this way, not only the light is lost due to reflection and the luminous flux is reduced, but also the light-emitting angle of the light-emitting diode lamp i...
