Therefore, a plurality of limiting protrusions 110 are arranged at intervals along the length direction of the mounting opening 103 on the side of the bottom of the mounting opening 103, so that the lampshade 200 is limited by the limiting protrusions 110.

In addition, the limiting boss 109 is provided with a positioning hole 111 with an opening pointing to the mounting hole 103, correspondingly, when the lampshade 200 is clamped in the mounting hole 103, a positioning protrusion 202 capable of being inserted into the positioning hole 111 is arranged on the part of the lampshade 200 corresponding to the positioning hole 111, and the mounting direction of the lampshade 200 can be identified through the matching of the positioning hole 111 and the positioning protrusion 202, so that the foolproof effect is achieved, and the mounting efficiency of the lampshade 200 is ensured. For the positioning protrusion 202, it may be cylindrical, prismatic, spherical, square, or boss-shaped, etc.

Referring to fig. 11, when the lamp housing 200 is installed, the positioning hole 111 at the bottom of the installation opening 103 of the housing 100 and the positioning protrusion 202 on the lamp housing 200 are first used as the foolproof identification distinguishing direction; then the lamp cover 200 is tilted so that the first side 203 of the lamp cover 200 is aligned with the first sidewall 120, thereby inserting the first protrusions 201 into the catching grooves 104; then, the second side 204 of the lampshade 200 is pressed into the light-emitting channel 101, so that the lampshade 200 is slightly deformed, and the second rib 205 on the second side 204 is clamped between the positioning surface 119 and the limiting protrusion 110, thereby completing the installation of the lampshade 200. In the mounting process, since the lamp cover 200 is deformed by pressing the lamp cover 200 from the width direction of the lamp cover 200, the housing 100 is less stressed and does not deform by damage.

Because the lamp shade 200 is clamped and fixed in the mounting opening 103 of the shell 100, the internal space of the lamp shell 100 is not occupied, the volume of the lamp can be reduced, and the attractiveness of the lamp can be improved. Moreover, the lamp shade 200 is clamped in the mounting opening 103 through the matching of the first convex rib 201 and the clamping groove 104 and the matching of the positioning surface 119, the limiting protrusion 110 and the second convex rib 205, so that the lamp shell 100 has enough structural strength, the lamp shell 100 is prevented from being damaged when the lamp shade 200 is clamped, and compared with the mode that the lamp shade 200 is mounted from the inside to the outside of the lamp, the lamp shell 100 is simple in structure, simple in mold, low in cost and high in structural strength; meanwhile, the part of the lampshade 200, which is just opposite to the light outlet channel 101, is not provided with a shielding part, so that a light outlet area of the lamp can be prevented from generating a local dark area, and the lampshade 200 is fixed in the existing mode of adopting a buckle and dispensing, so that a shading point exists.

Meanwhile, a part of the light emitted from the light-emitting side is directly emitted through the light-emitting channel 101 and passes through the lampshade 200, and the other part of the light is reflected to the light-emitting channel 101 through the light-reflecting side wall 108 and emitted; the dark area appears in the play light zone of avoiding lamps and lanterns for the light homoenergetic that the luminescent light sent can jet out, and the area of lamp shade 200 has all obtained effective utilization.

The embodiment further provides a lamp, which comprises the lampshade 200 mounting structure and the lampshade 200, wherein the lampshade 200 is clamped in the mounting opening 103; the lampshade 200 is provided with a first side 203 and a second side 204 which are opposite, the first side 203 is in clamping fit with the clamping groove 104, and the second side 204 is simultaneously supported by the positioning surface 119 and the limiting protrusion 110, so that the lampshade 200 is installed on the shell 100, the lampshade 200 does not occupy the inner space of the shell 100, the equidistant volume is reduced, and the attractiveness of the lamp is improved; moreover, the lamp shade 200 is clamped by the clamping surface extending along the mounting hole 103, so that the lamp shell 100 has enough structural strength, the lamp shell 100 is prevented from being damaged when the lamp shade 200 is clamped, and the lamp shell 100 has the advantages of simple structure, simple mold and low cost; meanwhile, the part of the lampshade 200, which is just opposite to the light outlet channel 101, is not provided with a shielding part, so that a local dark area in a light outlet area of the lamp can be prevented, and the attractiveness and the lighting performance of the lamp can be improved.

It should be understood that the light fixture also includes a light-emitting lamp, which may be a tungsten lamp, an incandescent lamp, or an LED, and in order to meet the energy-saving and environmental-friendly concept, most light fixtures used for illumination use employ LED lamps. The light emitting lamp can be directly installed in the housing 100 by only making the light emitting part of the light emitting lamp directly face the lamp hole 102 or inserting the light emitting part in the lamp hole 102; referring to fig. 8, for LED lamps requiring the use of a PCB board 117, the LED lamp is typically soldered to the PCB, and the PCB is then fixedly attached to the housing 100 on the opposite side of the light exit sidewall 107 such that the LED lamp is embedded within the lamp hole 102.

For a lamp powered by an external power source, the housing 100 is provided with a power line hole through which a power line passes, and a power switch of the lamp may be disposed on the housing 100 and may be disposed outside the housing 100.
