Technical Field

[0001] The utility model relates to the technical field of household and commercial lighting lamps, and in particular to a linear DOB lamp with full voltage input. Background Art

[0002] Downlights are a common home and commercial lighting equipment. As a type of downlight, built-in linear DOB downlights are powered by built-in linear DOB downlights. Compared with traditional external power downlights, built-in linear DOB downlights are small in size, simple in structure, easy to install, and suitable for use in various home and commercial places.

[0003] The above linear DOB downlight has a good lighting effect when in use, but there are still some problems: due to the change of power supply voltage and the different power supply voltages in different countries, its input power is unstable, thus affecting the lighting effect of the whole lamp. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a linear DOB lamp with full voltage input, using the installed linear power supply to detect changes in input voltage through an internal circuit, thereby ensuring that the power is stable under different voltages and achieving better lighting effects.

[0005] Another object of the utility model is to provide a linear DOB lamp with full voltage input. The top diffuser of the lamp body makes the light-emitting surface more uniform by adjusting the surface haze and the depth of the concave and convex. The internal groove interference fits the diffuser to eliminate the need for screw fixation, making it easy to install and produce.

[0006] In view of this, the utility model provides a linear DOB lamp with full voltage input, including a main body bottom shell, a face ring fixed at one end of the main body bottom shell, and a DOB lamp board arranged inside the main body bottom shell, the DOB lamp board is installed with LEDs and linear power supplies, the linear power supply is used to ensure stability under different voltages, the bottom of the DOB lamp board is fitted with an auxiliary heat dissipation structure located inside the main body bottom shell, a diffusion plate is clamped in the face ring, and a clip is arranged at one end of the main body bottom shell.

[0007] Preferably, a clip slot is provided on the main body bottom shell, the clip is clamped in the clip slot, and a clip card is provided on one side of the clip.

[0008] Preferably: a second mounting screw hole is provided on the DOB lamp board, a first mounting screw hole is provided inside the main body bottom shell, a fixing screw is installed on the DOB lamp board through the second mounting screw hole, and the fixing screw is matched and installed in the first mounting screw hole.

[0009] Preferably, a diffusion plate slot is provided on the inner wall of the face ring, and the diffusion plate is snap-connected in the diffusion plate slot.

[0010] Preferably, the diffusion plate comprises a PS haze plate and optical reflection dots, and the optical reflection dots are arranged on the end surface of the PS haze plate.

[0011] Preferably, the side surface of the main body bottom shell is provided with an oblique angle.

[0012] Preferably: the DOB lamp panel is electrically connected with a connecting wire that passes through the bottom shell of the main body.

[0013] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:

[0014] 1. The utility model is a linear DOB lamp with full voltage input. It uses the installed linear power supply to detect the change of input voltage through the internal circuit. When the input voltage is detected to be too high, the current flowing through the LED is reduced in time. When the input voltage is detected to be low, the current flowing through the LED is increased, thereby ensuring that the power is stable under different voltages, so that the lighting effect is better. At the same time, the full voltage input is suitable for use in any country with different power supply voltages in the world. The temperature on the DOB lamp board can be quickly dispersed by using the installed auxiliary heat dissipation structure. The linear power supply and the DOB lamp board are integrated, which saves the internal structure space, is easy to assemble, and effectively improves the production efficiency.

[0015] 2. The utility model is a linear DOB lamp with full voltage input. The diffuser plate on the top of the main body makes the light-emitting surface more uniform by adjusting the surface haze and the depth of the concave and convex. The internal groove interference clamping diffuser plate saves screw fixation, which effectively improves production efficiency.

[0016] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS
