Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the disclosed aspects may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.

In the related art, venue lighting refers to lighting applied to places such as stadiums, exhibition halls, hallways of museums, channels, venues, toilets, dressing rooms, and the like. Particularly in scenes such as stadiums, it is necessary to have the illumination light source projected in a fixed area in order to ensure the illumination effect and experience of field personnel.

In the related art, the light is generally cut off by adding a light cutting plate on the upper side of the lamp, so that the light can be emitted into a designated area, but the light cutting plate is simply added, only partial light cutting can be simply performed, the light irradiation range cannot be accurately controlled, and the adjustment cannot be performed according to the non-use requirement.

For example, in a stadium scene, if only a light interception plate is simply added on the upper side of the lamp, only part of light on the edge of the upper side of the lamp can be intercepted, the rest of light still diffuses and scatters to the periphery, the lamp is projected in the stadium and cannot form a good light interception effect, and meanwhile, a viewer opposite to the lamp still receives interference of strong light, so that the experience is poor.

How to realize accurate adjustment of the light irradiation area is a problem to be discussed and solved currently.

In order to solve the above problems, the embodiments of the present application provide a lighting fixture, in which a light source is disposed in a light source chamber formed by enclosing a reflective plate with a light source module, a left light-interception plate, and a right light-interception plate, and then light emitted from the light source chamber is reflected to an upper light-interception plate, the light source module, the left light-interception plate, and the right light-interception plate by the reflective plate to form a light-emitting surface, and is emitted from the light-emitting surface; through the arrangement, the light source is arranged in the light source cavity, the light is reflected out through the reflecting plate, the light can be collected, the illumination intensity is ensured, meanwhile, the light can be prevented from being scattered to the periphery to cause overlarge light irradiation area and difficult to control, the light is intercepted through the upper light interception plate, the left light interception plate and the right light interception plate, the proportion of the light emitting surface to the lamp body of the lamp shade is controlled through the proportion of the height of the width lamp shade of the window of the light source module, so that the accurate light interception is realized, the clear light cut-off line can be formed in the light irradiation area projected by the lamp, the light emitted by the light source to the reflecting plate is reflected by combining the arrangement of the reflecting plate, the light compensation can be carried out on the illumination area far relative to the illumination lamp, the whole illumination of the illumination area is uniform, and the illumination effect is good; and the angle of the upper light interception plate is adjustable, and the control of the size of the lamplight irradiation area is realized by adjusting the upper light interception plate, so that the lamplight irradiation area can be accurately controlled, and the requirements under various scenes are met.

By way of example, taking a stadium as an example, by using the lighting lamp in this application, the light source module 100 emits light to the reflecting plate 250, the reflecting plate 250 emits the light source 120 from the light emitting surface formed by enclosing the light interception plate, the overall ratio of the light emitting area to the lampshade 200 is controlled by the size ratio of the window 131 of the light source module 100 and the lampshade 200, and the setting of the reflecting plate 250 is combined, so that the light emitted by the lamp can be accurately controlled in the target area to form a clear cut-off line, and the overall illumination is uniform. For example, the light projection area is accurately cut off to the front of the audience space opposite to the lighting fixture, and the cut-off range of the light projection can also be controlled by adjusting the angle of the upper cut-off plate 230. Since the light source 120 of the lighting fixture of the present application is not directly opposite to the light emitting surface, but is reflected by the reflecting plate 250, strong light influencing experience to the viewer facing the lighting fixture can be avoided.
