Description

Technical Field

[0001] This utility model relates to a lamp whose light output can be manually adjusted. Background Technology

[0002] In the current technology, desk lamps usually adjust their brightness through electronic control. Because of the energy-saving characteristics of LED lamps, LED lamps are often used as the light source. The dimming technology of LED lamps is mainly achieved through PWM (pulse width modulation) dimming, which requires the use of dedicated LED lamp beads and drivers. Therefore, the cost of accurately adjusting the brightness of desk lamps is high.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned drawback of high cost associated with adjusting brightness in existing desk lamps using LED beads as the light source, this invention provides a solution: a lamp with manually adjustable light output, comprising: a front shell, a rear shell, a light-emitting component, and a light-blocking plate. The rear shell is connected to the front shell, and the light-emitting component is installed between the front and rear shells. The front shell has a light-emitting hole for light emitted by the light-emitting component to pass through. The light-blocking plate is slidably connected to the front shell and is located between the light-emitting hole and the light-emitting component. A handle on the light-blocking plate is used to drive the light-blocking plate to slide, thereby adjusting the amount of light emitted by the light-emitting component from the light-emitting hole.

[0005] As described above, a light fixture with manually adjustable light output has an adjustment handle located on one side of a light-blocking plate. The front housing has a strip-shaped hole for avoiding the adjustment handle. The adjustment handle includes a toggle part and a connecting part. The connecting part connects the toggle part and the light-blocking plate. The width and thickness of the connecting part are both smaller than the width of the strip-shaped hole, and the thickness of the toggle part is smaller than the width of the strip-shaped hole.

[0006] As described above, in a light fixture with manually adjustable light output, the adjustment handle is located on the front side of the light-blocking plate, and the adjustment handle passes through the light-emitting hole and can slide within the light-emitting hole.

[0007] As described above, a lamp with manually adjustable light output has a front housing with guide strips that slide with the two sides of a light-blocking plate. The light-blocking plate has an arc-shaped protrusion. The guide strip has a first positioning protrusion that engages with the arc-shaped protrusion to position the light-blocking plate in its current position when the light-blocking plate is in a position that completely blocks the light-emitting hole.

[0008] As described above, a light fixture with manually adjustable light output has a second positioning protrusion on the guide strip. When the light-blocking plate is in a position that does not completely block the light-emitting hole, it cooperates with the arc-shaped protrusion to position the light-blocking plate in the current position.

[0009] As described above, a lamp with manually adjustable light output has a ring-shaped enclosure on its rear shell, and the light-emitting component is located inside the enclosure.

[0010] As described above, a light fixture with manually adjustable light output has a light-transmitting plate detachably connected to the enclosure, and a mounting cavity for installing light-emitting components is provided between the light-transmitting plate, the enclosure, and the rear shell.

[0011] The light-emitting component of the lamp described above, which allows for manual adjustment of light output, comprises: a PCB board electrically connected to a power source and LED beads connected to the PCB board.

[0012] The beneficial effects of this utility model are:

[0013] 1. The lamp with manually adjustable light output of this utility model has a light output hole on the front shell through which the light emitted by the light-emitting component can pass, and a light-blocking plate is set between the light output hole and the light-emitting component. By adjusting the relative position of the light-blocking plate with respect to the light output hole, the amount of light passing through the light output hole of the light-emitting component can be adjusted, thereby adjusting the brightness, or even closing the light output hole. It can conveniently and easily adjust the light output manually, and is also inexpensive.

[0014] 2. The adjustment handle is set on the front side of the light-blocking plate. The adjustment handle passes through the light-emitting hole and can slide inside the light-emitting hole. The movement of the adjustment handle is restricted by the left and right sides of the light-emitting hole, thereby restricting the movement range of the light-blocking plate. This can simplify the mold, reduce costs, and prevent the light emitted by the light-emitting component from leaking out of the strip hole. Attached Figure Description

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 8 As shown, this utility model has two embodiments, which will now be described separately.

[0025] Example 1:

[0026] like Figures 1 to 5 As shown, this embodiment of a lamp with manually adjustable light output includes: a front shell 1, a rear shell 2, a light-emitting component 3, and a light-blocking plate 4. The rear shell 2 is connected to the front shell 1, and the light-emitting component 3 is installed between the front shell 1 and the rear shell 2. The front shell 1 has a light-emitting hole 101 for the light emitted by the light-emitting component 3 to pass through. The light-blocking plate 4 is slidably connected to the front shell 1 and is located between the light-emitting hole 101 and the light-emitting component 3. The light-blocking plate 4 has an adjustment handle 41 for driving the light-blocking plate 4 to slide and thereby adjusting the amount of light emitted by the light-emitting component 3 through the light-emitting hole 101. The lamp with manually adjustable light output of this utility model has a light-emitting hole on the front shell for the light emitted by the light-emitting component to pass through, and a light-blocking plate is set between the light-emitting hole and the light-emitting component. By adjusting the relative position of the light-blocking plate with respect to the light-emitting hole, the amount of light passing through the light-emitting component through the light-emitting hole can be adjusted, thereby adjusting the brightness, or even closing the light-emitting hole. It can conveniently and easily adjust the light output manually, and is also inexpensive.

[0027] In this embodiment, the adjustment handle 41 is located on one side of the light-blocking plate 4. The front shell 1 has a strip-shaped hole 102 for avoiding the adjustment handle 41. The adjustment handle 41 includes a toggle part 411 and a connecting part 412. The connecting part 412 connects the toggle part 411 and the light-blocking plate 4. The width and thickness of the connecting part 412 are both smaller than the width of the strip-shaped hole 102, and the thickness of the toggle part 411 is both smaller than the width of the strip-shaped hole 102. During assembly, the toggle part is first inserted into the strip-shaped hole 102 and then rotated 90° to achieve assembly between the light-blocking plate and the front shell. This method has the advantages of simple structure and convenient use.

[0028] In this embodiment, the front shell 1 is provided with guide strips 11 that slide with the two sides of the light-blocking plate 4. The light-blocking plate 4 is provided with arc-shaped protrusions 42. The guide strips 11 are provided with a first positioning protrusion 111 that engages with the arc-shaped protrusions 42 to position the light-blocking plate 4 in its current position when it is in a position that completely blocks the light-emitting hole 101. The engagement of the first positioning protrusion 111 and the arc-shaped protrusions 42 can position the light-blocking plate 4 in a position that completely blocks the light-emitting hole 101, preventing the light-blocking plate from moving after it closes the light-emitting hole.

[0029] Similarly, the guide strip 11 is provided with a second positioning protrusion 112, which engages with the arc-shaped protrusion 42 to position the light-blocking plate 4 in its current position when it is in a position that does not completely block the light-emitting hole 101. The engagement of the second positioning protrusion 112 and the arc-shaped protrusion 42 can position the light-blocking plate 4 in a position that does not completely block the light-emitting hole 101, thus preventing the light-blocking plate from moving.

[0030] In this embodiment, a ring-shaped enclosure 21 is provided on the rear shell 2, and the light-emitting component 3 is located inside the enclosure 21. A light-transmitting plate 5 is detachably connected to the enclosure 21. An installation cavity 200 for installing the light-emitting component 3 is provided between the light-transmitting plate 5, the enclosure 21 and the rear shell 2, which facilitates assembly and allows light to leak.

[0031] In this embodiment, the light-emitting component 3 includes: a PCB board 31 electrically connected to a power source and LED beads 32 connected to the PCB board 31.

[0032] Example 2:

[0033] The difference between this embodiment and Embodiment 1 is that in this embodiment, the adjusting handle 41 is located on the front side of the light-blocking plate 4. The adjusting handle 41 passes through the light-emitting hole 101 and can slide within the light-emitting hole 101. The movement of the adjusting handle 41 is limited by the left and right sides of the light-emitting hole 101, thereby limiting the movement range of the light-blocking plate. The above design simplifies the mold, reduces costs, and ensures that the light emitted by the light-emitting component 3 does not leak from the strip hole 102.

[0034] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
