Description

Technical Field

[0001] The present disclosure relates to the field of lamp lighting, and in particular to a lighting device and a lighting system with double knobs for adjusting color temperature. Background Art

[0002] LED lamps are widely used in people's daily lives due to their high luminous efficiency, good energy-saving effect, and long service life. However, commonly used LED lamps have a single light source, and a lamp can usually only emit a light beam of one color temperature. As living standards improve, people have further demands on the color temperature of lamps. For example, different ambient temperatures in different seasons and at different times require different lamp color temperatures to meet diverse needs. Therefore, a lamp that can adjust the color temperature is needed.

[0003] At present, there are two ways to adjust the color temperature of lamps on the market, one is system control, and the other is control by knob. System control is controlled by a remote control station or remote control, and is often used for basic lighting or group lighting. The debugging of exhibition lamps usually requires individual adjustment of the effects of exhibits. Therefore, system control is less convenient for debugging on the exhibition site. Generally, exhibition lamps adjust the color temperature by knob control. For example, a Chinese patent with application number CN202310537670.6 discloses a lamp color temperature adjustment method and system, including a lamp body, a lamp holder, a control circuit board, a color temperature control knob, a light intensity control knob, a first gear ring, a second gear ring, a drive assembly and two fixed assemblies; the two fixed assemblies are controlled to move out of the tooth groove, the limit of the color temperature control knob and the light intensity control knob is released, and the color temperature control knob and the light intensity control knob are turned to control the color temperature and light intensity of the lamp body.

[0004] However, the structural design of the above-mentioned lamp color temperature adjustment system has the following problems during use:

[0005] The above-mentioned lamp color temperature adjustment system adjusts the color temperature of the lamp through a color temperature control knob, that is, it is adjusted through a color temperature control knob, so that the stroke of the control knob is shorter. Since the color temperature value adjustment range of the lamp is wide, such as 1000K-10000K adjustment, the design of the radio button causes the color temperature division to be too coarse. A small rotation of the knob will cause a large fluctuation in the color temperature, that is, a small rotation of the knob will cause the color temperature to change by several hundred K, which in turn leads to problems such as low accuracy of color temperature adjustment and difficulty in correction.

[0006] Therefore, there is an urgent need for a lamp structure that can quickly, accurately and conveniently adjust the color temperature. Utility Model Content

[0033] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
