Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting, and in particular to an adjustable angle lighting lamp. Background Technology
[0002] Most lighting lenses are currently designed with a fixed angle, which makes it difficult to adjust the beam angle if different angles are required for different occasions.
[0003] To adjust the angle, a rotating mechanism is typically incorporated within the luminaire. An adjusting shaft controls the angle of the light source, thus adjusting the luminaire's angle. Alternatively, the angle can be adjusted by changing the fixed position of the lens, thereby altering the high and low beam effects. However, frequent adjustments to the lens or adjusting shaft can lead to wear on mechanical components, affecting adjustment accuracy and even causing the angle to become unstable. Adjusting the angle of the light source or lens may disrupt the original optical path design, resulting in uneven light spots and reduced lighting efficiency. To support the rotating adjustment function, the luminaire may require additional mechanical structures, making it more complex than a fixed design, and the precision of the adjustment is difficult to control. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide an adjustable angle lighting lamp that allows for adjustment of the lamp's illumination angle without the need for rotation. The overall structure is simple and the adjustment method is convenient.
[0005] An adjustable-angle lighting lamp includes a lens, a lamp panel, a plurality of LEDs, and a control board. The lens is disposed close to the lamp panel and has a plurality of small-angle and a plurality of large-angle light distribution rings. The plurality of LEDs are disposed on the lamp panel, and the positions of the LEDs correspond to the positions of the light distribution rings. The diameter of the LED is smaller than the width of the light distribution rings. The control board is disposed on the lens and is used to control the on / off state and power of the LEDs corresponding to the small-angle and large-angle light distribution rings, respectively.
[0006] The adjustable angle lighting lamp of this utility model can achieve the purpose of adjusting the beam angle by setting two light distribution rings with different angles and controlling the on / off state and brightness of the LEDs corresponding to the different light distribution rings individually through the control board; it can control the LEDs of the two light distribution rings to illuminate individually or to perform mixed lighting, which has a richer illumination angle and illumination range and can meet different lighting requirements.
[0007] Furthermore, the small-angle and large-angle apertures are arranged alternately. This alternating arrangement of the small-angle and large-angle apertures improves the light mixing effect.
[0008] Furthermore, the lens is a circular lens, and the small-angle and large-angle apertures are distributed in a ring shape around the lens. The ring-shaped apertures can provide uniform illumination around the object, and the light in the illuminated area is consistent. When mixing light, the uniform light emitted by the apertures at different angles results in a better light effect after mixing.
[0009] Furthermore, the lamp panel is a circular lamp panel, and the plurality of LEDs are distributed in a ring on the lamp panel, corresponding to the position of the light distribution ring on the lens.
[0010] Furthermore, the control panel is positioned at the center of the circular lens.
[0011] Furthermore, the lens is a square lens, and small-angle and large-angle light distribution rings are evenly spaced on the square lens as light distribution rings, wherein the small-angle and large-angle light distribution rings are arranged alternately; the control board controls the on / off state and brightness of the LED lights corresponding to the small-angle and large-angle light distribution rings respectively.
[0012] Furthermore, the light panel is a square light panel, and the plurality of LEDs are evenly spaced on the light panel and correspond to the position of the light distribution ring.
[0013] Furthermore, the control panel is equipped with a DIP switch with three adjustable positions, corresponding to the LED light corresponding to the small-angle aperture lighting up alone, the LED light corresponding to the large-angle aperture lighting up alone, and the LED lights corresponding to the small-angle aperture and the large-angle aperture lighting up simultaneously.
[0014] Furthermore, when the LED corresponding to the small-angle or large-angle aperture is lit alone, the LED outputs illumination at full power; when the LEDs corresponding to the small-angle and large-angle apertures are lit simultaneously, the LED outputs illumination at 50% power for light mixing.
[0015] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0018] Figure 3 This is a schematic diagram of the structure of the lamp board and LED lamp in this utility model. Detailed Implementation
[0019] Please see Figure 1-3 The adjustable-angle lighting lamp of this invention includes a lens 1, a lamp panel 2, several LEDs 3, and a control board 4. The lens 1 is provided with several small-angle light distribution rings 11 and several large-angle light distribution rings 12, wherein the small-angle light distribution rings 11 and the large-angle light distribution rings 12 are arranged alternately. The lamp panel 2 is disposed close to the lens 1, and the several LEDs 3 are disposed on the lamp panel 2, emitting light towards the lens 1. The diameter of each LED 3 is smaller than the width of the light distribution rings. The light emitted by the LEDs 3 is more concentrated when passing through the small-angle light distribution rings 11, while the light emitted through the large-angle light distribution rings 12 is wider. The control board 4 controls the switching on and off and the power of the LEDs 3, achieving the purpose of controlling the beam angle by controlling the on / off state and brightness of the LEDs 3 at different light distribution angles.
[0020] In this embodiment, the lens 1 is a circular lens 1, and the aperture rings are distributed in a ring shape around the center of the lens 1. The small-angle aperture rings 11 and the large-angle aperture rings 12 are arranged alternately. The ring-shaped aperture rings can provide uniform illumination around the object, ensuring consistent light across the irradiated area. Furthermore, during light mixing, the uniform light emitted from aperture rings at different angles results in a better overall light effect after mixing.
[0021] The light panel 2 is a circular light panel 2, and the plurality of LEDs 3 are distributed in a ring on the light panel 2, corresponding to the positions of the light distribution rings on the lens 1. The lens 1 is in close contact with the light panel 2, and the diameter of the LED 3 is smaller than the width of the light distribution ring. The light emitted by the LED 3 only passes through the corresponding light distribution ring and does not illuminate the adjacent light distribution rings, ensuring that the light from a single LED 3 passes through only a single light distribution ring.
[0022] The control board 4 is located at the center of the circular lens 1. The control board 4 is equipped with a DIP switch 41, which has three adjustable positions, corresponding to the individual illumination of the LED 3 corresponding to the small-angle aperture 11, the individual illumination of the LED 3 corresponding to the large-angle aperture 12, and the simultaneous illumination of the LEDs 3 corresponding to both the small-angle and large-angle apertures 12. When the LED 3 corresponding to either the small-angle or large-angle aperture 12 is illuminated individually, it is controlled to output full power. When the LEDs 3 corresponding to both the small-angle and large-angle apertures 12 are illuminated simultaneously, each LED 3 is controlled to output 50% power for illumination, resulting in light mixing to achieve a mid-angle light distribution.
[0023] In another embodiment, the lens 1 is a square lens, on which small-angle and large-angle light distribution rings are evenly spaced. These small-angle and large-angle light distribution rings are arranged alternately, and the illumination angle is adjusted by using the two shapes of the small-angle and large-angle light distribution rings. The on / off state and brightness of the LEDs corresponding to the small-angle and large-angle light distribution rings are controlled individually, with the intermediate angle achieved through light mixing. The lamp panel 2 is a square lamp panel 2, and the plurality of LEDs 3 are evenly spaced on the lamp panel 2, corresponding to the positions of the light distribution rings.
[0024] The adjustable angle lighting lamp of this utility model can adjust the beam angle by setting two light distribution rings with different angles and controlling the on / off state and brightness of the LED lamps 3 corresponding to different light distribution rings individually through the control board 4. It can control the LED lamps 3 of the two light distribution rings to illuminate individually or to perform mixed lighting, which has a richer illumination angle and illumination range and can meet different lighting requirements.
[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
