[0031] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] A lamp structure for diffuse reflection light emission, comprising:

[0033] A reflector cup having a through mounting hole;

[0034] A heat dissipation component, at least a portion of which is disposed within the reflector cup through the mounting hole;

[0035] A light source assembly is disposed inside the reflector cup and along the side wall of the heat dissipation assembly.

[0036] As can be seen from the above description, the beneficial effects of this utility model are as follows: by setting mounting holes on the reflector, a part of the heat dissipation component can be set inside the reflector through the mounting holes, thereby enabling the light source component to be set along the side wall of the heat dissipation component, avoiding glare caused by direct light emission of the light source component, and making it easier to assemble the light source component and the heat dissipation component.

[0037] Furthermore, the heat dissipation assembly includes a horizontal mounting portion and a raised mounting portion; it also includes a drive plate, which is disposed on the horizontal mounting portion and has a through hole; the raised mounting portion passes through the through hole and the mounting hole, such that at least a portion of it is disposed inside the reflector cup.

[0038] As described above, by configuring the heat dissipation component to include a horizontal mounting part and a raised mounting part, and by providing avoidance holes on the driver board so that the driver board can be mounted on the horizontal mounting part, and by mounting the light source component through the raised mounting part, so that both the light source component and the driver board are mounted on the heat dissipation component, not only is the overall heat dissipation effect improved, but also the light source component and the driver board are made easier to connect and form an electrical connection.

[0039] Furthermore, a first positioning element is provided on the horizontal mounting part; a second positioning element adapted to the positioning element is provided on the drive plate.

[0040] As can be seen from the above description, by setting a first positioning member on the horizontal mounting part and a corresponding second positioning member on the drive board, the cooperation between the first positioning member and the second positioning member makes it easier to install the drive board on the heat dissipation assembly and improves the stability of the drive board.

[0041] Furthermore, the light source assembly includes a flexible light source plate; the protruding mounting portion is a column; and the flexible light source plate is disposed on the side of the protruding mounting portion.

[0042] As described above, the light source assembly uses a flexible light source plate and the protruding mounting part is set as a column, so that the flexible light source plate can fit the side of the protruding mounting part, making the light source assembly easier to install.

[0043] Furthermore, the protruding mounting portion is a cylinder; the light sources on the flexible light source plate are arranged at equal intervals.

[0044] As described above, by setting the protruding mounting part as a cylinder and setting the light sources on the flexible light source plate at equal intervals, the light can be evenly emitted onto the reflector cup, thus improving the light output effect.

[0045] Furthermore, it also includes a cover plate; the cover plate is disposed on the top of the protruding mounting portion and covers the protruding mounting portion.

[0046] As can be seen from the above description, by setting a cover plate on the top of the protruding mounting part, the light source component and heat dissipation component are shielded.

[0047] Furthermore, the inner side of the reflector cup is a diffuse reflective surface.

[0048] As described above, by setting the inner side of the reflector as a diffuse reflective surface, light can be emitted in a diffuse reflection manner, thus avoiding glare problems.

[0049] Furthermore, it also includes a transparent protective cover; the transparent protective cover is arranged around the light source of the light source assembly; and a refractive structure is provided on the side of the transparent protective cover away from the light source assembly.

[0050] As described above, by surrounding the light source of the light source assembly with a transparent protective cover, the light source on the light source assembly can be isolated from other components to prevent contact with charged light sources; and the addition of a refractive structure allows light to be better refracted to the reflector cup.

[0051] Furthermore, it also includes a housing; the housing is provided with a mounting groove; the reflector and the light source assembly are both disposed in the mounting groove; the groove opening plane of the mounting groove is not lower than the cup opening plane of the reflector.

[0052] As described above, by setting a mounting groove inside the housing and ensuring that the groove opening plane is not lower than the cup opening plane of the reflector, the housing effectively protects the reflector and the light source assembly.

[0053] Furthermore, a DIP switch is provided on the housing.

[0054] As described above, the lighting fixtures can be controlled by connecting the DIP switch to the circuit on the driver board.

[0055] Furthermore, the reflector is threadedly connected to the housing.

[0056] As can be seen from the above description, connecting the reflector cup to the housing via threads not only facilitates the connection between the reflector cup and the housing, but also improves the stability of the reflector cup.
