Problems solved by technology

[0005] But along with this elastic force, there will also be inevitable friction in the downlight, which will greatly affect the service life of the downlight, and the self-weight of the light-emitting module must be considered when choosing this spring
In addition, since the spring that controls the lifting of the light-emitting module in the housing is located on the back of the ceiling, it is difficult to adjust the rise and fall of the light-emitting module on the front of the ceiling when the downlight has been installed on the ceiling

Abstract

The invention relates to a light-emitting device (100) for being arranged on an assembling plate (A) provided with an assembling hole (3). The light-emitting device (100) comprises a shell (1) and a light-emitting module (2), wherein the light-emitting module (2) is arranged in the shell (1) and can move longitudinally relative to the shell (1); the shell (1) is arranged on a first side (S1) of the assembling plate (A). The light-emitting device (100) is characterized by further comprising an adjusting mechanism, wherein the adjusting mechanism comprises an operating piece (4) arranged on the second side (S2), which is opposite to the first side (S1), of the assembling plate (A), and a first adjusting component and a second adjusting component which are arranged on the shell (1) and the light-emitting module (2) respectively; the operating piece (4) interacts with the first adjusting component, and the first adjusting component interacts with the second adjusting component so as to at least allow the light-emitting module (2) to move longitudinally relative to the shell (1) via the assembling hole (3).

Description

technical field [0001] The invention relates to a lighting device, in particular a downlight, for mounting on a mounting plate, such as a ceiling. Background technique [0002] Downlight is a common lighting device widely used in offices, halls and auditoriums. Downlights are embedded into the roof or wall to ensure an aesthetic effect. [0003] In recent years, as the application of LED lights has become more and more extensive, LED light sources have also begun to be more and more applied to downlights. In order to meet the needs of various application occasions, the light-emitting module in the downlight is fixed in the light-emitting device in a liftable manner. Therefore, it can be adjusted so that the light emitting surface of the downlight and its assembly surface are on the same plane, so as to obtain the outgoing light perpendicular to the assembly surface. It is also possible to make the light-emitting module pivotally fixed in the downlight extend out of the mo...
