Description

A projection wall lamp

Technical Field

The present invention relates to the field of lighting technology, and more particularly to a projection wall lamp.

Background technique

The current projection wall lamps are usually installed on one wall, called the installation wall. When in use, the image of the wall lamp will be projected onto another wall or the ground, called the projected wall. This projection method requires a large space. During the projection process, the light needs to go through a certain route to reach the projected wall. When objects block the projection route, the projection effect is affected; and when people walk between the projection lamp and the projected wall, the light of the projection lamp can easily hurt people's eyes and cause dazzle.

Summary of the invention

In order to overcome the problem in the prior art that the projection lamp needs to be far away for projection, the present invention provides a projection wall lamp which can project images onto the installation wall, thereby avoiding the need for the image of the projection lamp to be projected from a long distance onto the projected wall.

In order to achieve the above-mentioned purpose, a technical solution is provided, namely, a projection wall lamp, comprising a front cover and a rear cover, wherein a projection accessory and a light exit hole located at the front end of the projection accessory are installed on the rear cover, and the opening direction of the light exit hole is toward the direction of the projection accessory; a light-emitting component is installed between the front cover and the rear cover, and the light of the light-emitting component is scattered through the light exit hole.

The light of the light emitting component is scattered to the outside through the light exit hole. The light propagates in a straight line, so the light is scattered in the direction of the projection accessory. Due to the obstruction of the projection accessory, the light projects the pattern of the projection accessory onto the wall where the projection wall lamp is installed.

Preferably, an inner bracket is installed on the front cover, and the light-emitting component is installed on the inner bracket. The inner bracket separates the light-emitting component and the front cover, avoiding the need to open a hole on the front cover to fix the light-emitting component, which affects the aesthetics, and can also reduce the heat dissipation to the front cover, causing deformation of the front cover and affecting the appearance.

Preferably, a projection accessory assembly seat is installed on the inner bracket, the projection accessory assembly seat is provided with a slot platform with a slot, and the rear cover is provided with a connecting port connected to the slot platform. The projection accessory is inserted into the slot through the connecting port to fix the projection accessory. At the same time, it is also convenient to replace the projection accessory, and the projection accessory can be quickly removed from the slot and replaced with the image to be projected.

Preferably, the inner bracket is provided with a mounting slot and a fixing block, the bottom surface of the slot platform abuts against the upper end surface of the fixing block, and the edge of the bottom surface of the slot platform is embedded in the mounting slot. The bottom surface of the slot platform abuts against the upper end surface of the fixing block, limiting the downward movement of the projection accessory assembly seat, and the edge of the bottom surface of the slot platform is embedded in the mounting slot, limiting the movement of the projection accessory assembly seat toward the front cover. When the front cover and the rear cover are closed, the movement of the projection accessory assembly seat toward the rear cover is limited.

More preferably, a fixing frame is provided on the communication port, and the slot platform extends into the fixing frame. The slot platform extends into the fixing frame, which again limits the movement of the projection accessory assembly seat in the left and right directions. Through the action of the limiting members at different positions, the projection accessory assembly seat can be fixed in the projection wall lamp without fasteners.

Preferably, a diffuser is provided at one end of the projection accessory assembly seat close to the light emitting component, and the diffuser separates the light exit hole and the light emitting component. The diffuser diffuses the light of the light emitting component to obtain a larger projection range. The diffuser is installed on the projection accessory assembly seat, which facilitates the installation and removal of the diffuser, and does not require installation by fasteners, and the structure is simpler.

Preferably, the projection accessory assembly seat is provided with an air-avoiding groove at one end close to the light-emitting component, and a card slot is provided on the side of the air-avoiding groove, and the diffuser is installed in the card slot. Light is incident on the diffuser through the air-avoiding groove, and the diffuser is installed through the card slot. When it needs to be disassembled and replaced, it can be directly taken out without the assistance of tools, and the use of fasteners on the diffuser is reduced to affect the heat dissipation of the diffuser.

Preferably, the inner bracket is connected to the front cover by snapping, the four end corners of the front cover are provided with claws, and the inner bracket is provided with corresponding claw grooves. The inner bracket is connected to the front cover by snapping, which facilitates the assembly and disassembly of the inner bracket.

Preferably, the rear cover includes a mounting and fixing portion and a projection accessory portion, the angle between the projection accessory portion and the mounting and fixing portion is an obtuse angle, the front cover fits the rear cover, and the bending angle of the front cover is consistent with the angle of the rear cover. The projection accessory portion is inclined inward, and the light outlet hole only needs a normal opening to face the direction of the projection accessory. The front cover and the rear cover can fit tightly together without light leakage.

Compared with the prior art, the beneficial effects are:

The present invention provides a light outlet at the front end of the projection accessory, and the light outlet direction of the light outlet is toward the projection accessory, so that the image of the projection accessory is projected on the wall where the projection wall lamp is installed, thereby reducing the projection space required by the projection wall lamp. The light outlet and the projection accessory, and the distance between the projection accessory and the wall are all behind the projection wall lamp, and the projection is not projected in other directions, so there will be no obstacles affecting the projection effect, and the projected light will also be added to people and hurt their eyes.
