Description

Technical Field

[0001] This utility model relates to the technical field of lighting equipment, and specifically to an adjustable lamp. Background Technology

[0002] Lighting equipment is used to provide light sources and lighting effects, such as lamps. Most conventional lamps have only one light source, and the light source only has two states: on and off. Moreover, its brightness and illumination range are fixed. However, different usage scenarios have different requirements for brightness and illumination range. Therefore, multiple light sources are set up to increase brightness and illumination range. However, multiple light sources also only have two states: all on and all off. So the brightness and illumination range are still fixed. Summary of the Invention

By rotating a knob, a signal is sent to a circuit board, which controls the number of light sources that are on and off, as well as the power of each light source, thereby adjusting the brightness and illumination range. Therefore, it can be applied to different usage scenarios, thus solving the problem that the brightness and illumination range of existing lamps are fixed.

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-5 As shown, an adjustable lamp includes a circuit board 1, on which a knob 2 and a lamp plate 3 are provided, and at least two light sources are provided on the lamp plate 3. The knob 2 and the lamp plate 3 are electrically connected to the circuit board 1. By rotating the knob 2, a signal is sent to the circuit board 1, thereby allowing the circuit board 1 to control the number of light sources that are on and off and the power supplied to each light source, thereby adjusting the brightness and illumination range.

[0032] Therefore, in actual use, by setting at least two light sources and adapting to the rotating knob 2, the rotating knob 2 can send a signal to the circuit board and allow the circuit board 3 to control the number of light sources on and off as well as the power supplied to the light sources, thereby adjusting the brightness and illumination range, thus making it suitable for different usage scenarios.

[0033] The number of light sources can be selected according to different usage scenarios. This utility model uses nine, that is, nine light sources are set on the light panel 3, and the nine light sources are light source one 31, light source two 32, light source three 33, light source four 34, light source five 35, light source six 36, light source seven 37, light source eight 38 and light source nine 39 respectively.

[0034] Meanwhile, the nine light sources are in three states: in state one, light source 5 (35) is on and the others are off; in state two, light sources 2 (32), 4 (34), 5 (35), 6 (36), and 8 (38) are on and the others are off; in state three, light sources 1 (31), 2 (32), 3 (33), 4 (34), 5 (35), 6 (36), 7 (37), 8 (38), and 9 (39) are all on.

[0035] Therefore, in actual use, the angle of rotation of knob 2 indicates which state to enter, and the number of light sources on and off is different in each state, resulting in different brightness and illumination range.

[0036] Secondly, in state one, light source 5 35 gradually brightens as knob 2 is rotated; in state two, light source 5 35 gradually dims as knob 2 is rotated, and light sources 2 32, 4 34, 6 36 and 8 38 gradually brighten as knob 2 is rotated; in state three, light source 5 35 first gradually dims and then gradually brightens as knob 2 is rotated, and light sources 2 32, 4 34, 6 36 and 8 38 first gradually dim and then gradually brighten as knob 2 is rotated, and light sources 1 31, 33, 7 37 and 9 39 gradually brighten as knob 2 is rotated.

[0037] This is because the total power changes as knob 2 is rotated; that is, the total power increases as knob 2 is rotated. Furthermore, in each state, the final state is that the power of each light source is the same, thus the brightness of each light source also changes, resulting in a more uniform brightness and preventing any light source from being too bright or too dim. Moreover, due to the increase in total power, the overall brightness also increases to some extent.

[0038] like Figures 1-5 As shown, other structures include: a housing 4, with a placement groove 41 at the bottom of the housing 4, and a circuit board 1 at the opening of the placement groove 41; and a lens 5 is provided on the housing 4 corresponding to the lamp board 3.

[0039] The structure of lens 5 is as follows: First, a groove 51 is provided at the bottom of lens 5 corresponding to lamp plate 3, and the bottom of groove 51 is a downward protruding arc surface. Therefore, in actual use, the downward protruding arc surface can concentrate the light and thus ensure the brightness.

[0040] Furthermore, the mounting structure of lens 5 is as follows: First, the bottom of lens 5 is connected to circuit board 1 via fasteners, wherein the fasteners are screws. Simultaneously, a mounting platform 42 is provided on the top of housing 4, and a through hole 43 is provided in the middle of the mounting platform 42. A protrusion 44 is provided on the inner wall of the through hole 43, and a corresponding locking groove 52 is provided on lens 5. Therefore, in actual use, the matching of the protrusion 44 and the locking groove 52 achieves connection while also serving a limiting function.

[0041] like Figures 1-5 As shown, the structure of the knob 2 is as follows: First, the knob 2 includes a variable resistor 21 and a knob cap 22. The variable resistor 21 includes a rotating shaft 211. The bottom of the knob cap 22 is provided with a mounting groove 221. The mounting groove 221 contains a protrusion 222. The top of the rotating shaft 211 is located in the mounting groove 221. The top of the rotating shaft 211 is provided with a slot 212 corresponding to the protrusion 222.

[0042] Therefore, in actual use, the connection is achieved by the top of the rotating shaft 211 being located within the mounting groove 221 and the mating of the protrusion 222 and the slot 212. Furthermore, the variable resistor 21 works by changing the resistance and thus the current through the rotation of the rotating shaft 211, thus providing different signals to the circuit board 1. Since the structure of this variable resistor 21 is existing and readily available, it will not be discussed further.

[0043] Secondly, a protrusion 223 is provided on the outer side of the cap 22, and the protrusion 223 abuts against the inner side of the housing 4 to limit its position, and the housing 4 has an opening to expose the cap 22.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
