Description

Technical Field

[0002] LED chips come in various color temperatures. To achieve multi-color temperature light output in the same lamp, it is generally achieved by using LED chips with multiple color temperatures. However, existing lamps can generally only achieve multi-color temperature light output from a single angle and cannot achieve multi-color temperature light output from multiple angles, thus their applicability is not high. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a multi-angle multi-color temperature lamp and a dimming circuit.

[0004] A multi-angle, multi-color-temperature lamp according to a first aspect embodiment of the present invention includes: a lamp housing, one end of which has an opening, an LED lamp panel disposed within the lamp housing, a light-transmitting plate disposed at the opening, a first LED bead group and a second LED bead group disposed on the LED lamp panel, the first LED bead group being disposed in the inner ring region of the LED lamp panel, the second LED bead group being disposed in the outer ring region of the LED lamp panel, the first LED bead group and the second LED bead group each including LED beads of at least two color temperatures, a first lens disposed in the region of the light-transmitting plate opposite to the first LED bead group, and a second lens disposed in the region of the light-transmitting plate opposite to the second LED bead group, wherein the first lens and the second lens have different emission angles.

[0005] According to some embodiments of the present invention, the emission angle of the first lens is greater than that of the second lens.

[0006] According to some embodiments of the present invention, the other end of the lamp housing is also provided with an opening, and there are two LED lamp panels and two light-transmitting panels respectively disposed at both ends of the lamp housing.

[0007] According to some embodiments of the present invention, the lamp housing is provided with an outwardly protruding connecting arm in the middle.

[0008] According to the dimming circuit of the second aspect of the present invention, applied to the above-mentioned multi-angle multi-color temperature lamp, it includes a driving power supply and switches K1, K2 and K3 respectively electrically connected to the driving power supply. Switch K1 is electrically connected to the anode of the first lamp group and the anode of the second lamp group respectively. Switches K2 and K3 are both electrically connected to the cathode of the first lamp group and the cathode of the second lamp group.

[0009] The dimming circuit includes a power regulation module electrically connected to the drive power supply.

[0010] The multi-angle, multi-color-temperature lamp and dimming circuit according to the embodiments of this utility model have at least the following beneficial effects: Since the first lamp group and the second lamp group each include lamps of at least two color temperatures, there are three color temperature states when the first lamp group is lit, and there are also three color temperature states when the second lamp group is lit. Furthermore, since the distribution positions of the first lamp group and the second lamp group are different, a total of nine light emission modes are formed, which makes the applicability wider. In addition, since the light emission angles of the first lens and the second lens are different, multi-color-temperature light emission is achieved at multiple angles, further improving the applicability.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] Reference Figures 1 to 2This utility model discloses a multi-angle, multi-color-temperature lamp, comprising: a lamp housing 10, an opening at one end of the lamp housing 10, an LED lamp panel 20 disposed within the lamp housing 10, a light-transmitting plate 30 disposed at the opening, a first LED bead group 21 and a second LED bead group 22 disposed on the LED lamp panel 20, the first LED bead group 21 being disposed in the inner ring area 200 of the LED lamp panel 20, and the second LED bead group 22 being disposed in the outer ring area of ​​the LED lamp panel 20, the first LED bead group 21 and the second LED bead group 22 respectively comprising LED beads of at least two color temperatures, a first lens disposed on the area of ​​the light-transmitting plate 30 opposite to the first LED bead group 21, and a second lens disposed on the area of ​​the light-transmitting plate 30 opposite to the second LED bead group 22, the first lens and the second lens having different light emission angles. Since the first LED group 21 and the second LED group 22 each include LEDs with at least two color temperatures, the first LED group 21 will have three color temperature states when it is lit, and the second LED group 22 will also have three color temperature states when it is lit. Furthermore, since the first LED group 21 and the second LED group 22 are distributed in different positions, a total of nine light emission modes are formed, making it more applicable. In addition, since the first lens and the second lens have different light emission angles, multi-color temperature light emission and multi-angle light emission can be achieved simultaneously, further improving applicability.

[0019] In some embodiments, the light emission angle of the first lens is greater than that of the second lens; the light emission angle of the first lens may also be less than that of the second lens, and the specific light emission angle can be set according to actual needs.

[0020] In some embodiments, the other end of the lamp housing 10 is also provided with an opening, and there are two LED lamp panels 20 and two light-transmitting panels 30 respectively, which are respectively provided at both ends of the lamp housing 10, so that both ends of the lamp can emit light, which is suitable for a variety of occasions.

[0021] Furthermore, the lamp housing 10 has an outwardly protruding connecting arm 11 in the middle, which facilitates fixing it to the wall.

[0022] like Figure 2 This application also includes a dimming circuit applied to the aforementioned multi-angle, multi-color-temperature lamp, comprising a conventional driving power supply and switches K1, K2, and K3 electrically connected to the driving power supply respectively. Switch K1 is electrically connected to the anode of the first lamp group and the anode of the second lamp group 22 respectively. Switch K1 is used to select and turn on at least one of the first lamp group and the second lamp group. Switches K2 and K3 are both electrically connected to the cathode of the first lamp group and the cathode of the second lamp group 22.

[0023] Specifically, in practical applications, both the first LED bead group 21 and the second LED bead group 22 include LED beads with two color temperatures: 3000K and 5000K. The first lens is 60 degrees and the second lens is 25 degrees. LED light panels 20 are provided at both the upper and lower ends of the lamp housing 10. Switches K1, K2, and K3 are electrically connected to the LED light panels 20 at the upper and lower ends, respectively. Switch K1 is used to select three modes: the upper light panel is lit, the lower light panel is lit, and both light panels are lit simultaneously. By combining switches K1, K2, and K3, the color temperature can be freely switched, and three different light emission angles and nine different mode states can be achieved.

[0024] Mode 1: The light emission angle is 60°, and the first LED group 21 emits light from LEDs with a color temperature of 3000K.

[0025] Mode 2: Light emission angle 60°, 5000K color temperature LEDs of the first LED group 21 emit light;

[0026] Mode 3: Light emission angle 60°, first LED group 21 LEDs with a color temperature of 4000K emit light;

[0027] Mode 4: Light emission angle 25°, 3000K color temperature LEDs of the second LED group 22 emit light;

[0028] Mode 5: Light emission angle 25°, 5000K color temperature LEDs in the second LED group 22 emit light;

[0029] Mode 6: Light emission angle 25°, second LED group 22 LEDs with a color temperature of 4000K emit light;

[0030] Mode 7: Light emission angle 40°, first LED group 21 3000K + second LED group 22 3000K color temperature LEDs emit light;

[0031] Mode 8: Light emission angle 40°, first LED group 215000K + second LED group 22 5000K color temperature LEDs emit light;

[0032] Mode 9: Light emission angle 40°, 3000K color temperature LEDs of the first LED group 21 emit light + 3000K color temperature LEDs of the second LED group 22 emit light + 5000K color temperature LEDs of the first LED group 21 emit light + 5000K color temperature LEDs of the second LED group 22 emit light.

[0033] Among them, switch K1 is used to switch between upper and lower light output;

[0034] When switch K2 is switched to mode 4, 5, 6, or 7, switch K3 must be switched to position A (neutral).

[0035] When switch K3 is switched to mode 1, 2, 3, or 8, switch K2 must be switched to position 0 (neutral).

[0036] When switch K2 is switched to mode 7 and switch K3 is switched to mode 8 at the same time, mode 9 function is achieved; when switches K2 and K3 are switched to the 0 / A position at the same time, the light fixture does not turn on.

[0037] Furthermore, it includes a power regulation module electrically connected to the drive power supply, the power regulation module employing existing technology, such as... Figure 2 As shown, the power regulation module includes a switching chip WATT and multiple range resistors electrically connected to the switching chip WATT. The power of the corresponding range is selected by selecting the corresponding resistor through the switching chip WATT.

[0038] It will be readily understood by those skilled in the art that the above preferred methods can be freely combined and superimposed without conflict.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
