Detailed Description

For further understanding of the features and technical means, as well as the specific objects and functions of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. The description herein of the positional relationship of the components with respect to the upper, lower, inner, outer, etc. merely shows the relative relationship of the components in the state shown in the drawings, and does not represent an absolute limitation of the scope of the present invention.

Refer to fig. 1. A front-loading commercial lighting lamp with a replaceable light source comprises a bracket 1 and a lamp body 2 installed on the bracket 1. The support 1 comprises a frame 11 and a sleeve 12 arranged inside the frame 1. Frame 11 is used for fixing on the ceiling suspended ceiling, and for being fixed, 11 both sides of frame can set up torsional spring 13. Refer to fig. 2 and 3. The sleeve 12 is used for mounting the lamp bodies 2, the number of the sleeve 12 can be one or more than one, one or more lamp bodies 2 can be mounted on one support 1, and in order to mount the lamp bodies 2, the inner side surface of the upper end edge of the sleeve 12 is provided with a chamfer 14.

Refer to fig. 4 to 6. The lamp body 2 comprises a radiator 21, a cavity 20 is arranged in the radiator 21, an LED lamp bead 22 is arranged in the cavity 20, and a reflecting cup 23 sleeved on the periphery of the LED lamp bead 22 is arranged in the cavity. Two sides of the opening end of the cavity 20 of the heat sink 21 are respectively provided with a cantilever 211, and a fixing ring 25 matched with the sleeve 21 is fixed on the cantilever 211 by a screw 23. The fixed ring 25 can swing around the fixed point of the fixed ring and the cantilever 211 so as to adjust the emergent angle of the lamp light. One side of the upper end of the fixing ring 25 is provided with a circular arc-shaped abdicating notch 251, so that the length of the cantilever 211 can be shortened, and the product is more compact. Three spring pieces 26 are equally spaced around the side wall of the fixing ring 25, and arc-shaped salient points 261 facing the outside of the fixing ring 25 are arranged on the spring pieces 26. The fixing ring 25 penetrates into the sleeve 12 of the support 1, and the salient points 261 of the elastic sheets 26 on the fixing ring 25 are clamped on the upper end face of the sleeve 12, so that the lamp body 2 is fixed on the support 1. The inner side of the upper end face of the sleeve 12 is provided with a chamfer 121, so that the salient points 214 can be more smoothly clamped into and pulled out of the sleeve 12, and the lamp body 2 can be more conveniently assembled and disassembled. The elastic sheet 26 may be an independent component mounted on the outer side of the side wall of the fixing ring 25, or may be directly formed by processing the side wall of the fixing ring 25. The latter is preferred in the present invention, specifically, the fixing ring 25 is formed by injection molding of plastic, an inverted U-shaped slit 252 is formed on the side wall of the fixing ring 25, the half-surrounded portion of the slit 252 forms the spring plate 26, the upper end and both sides of the spring plate 26 are separated from the side wall of the fixing ring 25, the lower end of the spring plate 26 is connected with the side wall of the fixing ring 25, and the upper end of the spring plate 26 is provided with a circular arc-shaped protruding point 261. Thus, when the convex points 261 are pressed, the elastic pieces 26 can be bent toward the inside of the fixing ring 25.

The assembly and disassembly mode of the utility model is as follows: firstly, fixing a frame 11 of a bracket 1 on a ceiling, specifically fixing the frame 11 in a reserved mounting hole of the ceiling through a torsion spring 13, or directly fixing the frame 11 on the ceiling by adopting a screw; then the lamp body 2 is inserted into the sleeve 12 of the support 1 from the lower part, the spring sheet salient points 261 on the lamp body fixing ring 25 are extruded by the inner wall of the sleeve 12, the spring sheets 26 are bent towards the fixing ring 25, when the salient points 261 cross the upper end face of the sleeve 12, the spring sheets 26 are restored to the original state, and the salient points 261 are clamped on the edge of the upper end of the sleeve 12 to fix the lamp body 2 on the support 1; when the lamp body 2 is detached, the lamp body is directly pulled out towards the lower part of the bracket 1, the elastic sheet 26 is bent towards the inner part of the fixing ring 23, and the salient point 261 is separated from the upper end surface of the sleeve 12.

According to the utility model, due to the design that the support and the lamp body are separated, after the lamp body is damaged or the service life is exhausted, only the lamp body needs to be replaced, the support does not need to be replaced, the replacement cost of the lamp is low, and meanwhile, the lamp body is fixed by the elastic sheet, so that the lamp body is easier to disassemble and assemble.
