Please also refer to FIG. 3A , the lamp holder 120 includes a light emitting module 140 . Both ends of the light pole 150 are respectively connected to the base 110 and the lamp base 120 . Specifically, the light pole 150 further includes a first pole body 151 and a second pole body 152 connected to the first pole body 151 , wherein the first pole body 151 can rotate relative to the second pole body 152 . The touch module 130 can be optionally disposed in the base 110 , the lamp holder 120 or the lamp post 150 , and electrically connected to the light emitting module 140 to adjust the color temperature and/or brightness of the light emitting module 140 .

The following will take the light-emitting module 140 installed on the lamp holder 120 as an example to make a detailed description. As shown in FIG. 1, FIG. 2 and FIG. and a diffuser 148 . The reflective sheet 146 and the diffuser sheet 148 are respectively arranged on opposite side surfaces of the light guide plate 144. The shape of the light guide plate 144 is preferably circular in this embodiment; however, in other different embodiments, the shape of the light guide plate 144 can also be is oval, rectangular, triangular, or other suitable geometric shapes, without limitation. The main function of the light guide plate 144 is to control the scattering direction of the light, so as to make the light and color of the LED light bar 142 more uniform. The role of the diffuser 148 (Diffuser) is to make the distribution of emitted light more uniform, and even a Prism/lenticular sheet (Prism/lenticular sheet) with a light-condensing effect can be added on the diffuser 148 to increase the directionality of the emitted light to achieve The purpose of increasing the brightness of the front. The reflector 146 (Reflector) reflects the light leaked from the bottom surface back into the light guide plate 144 to prevent the light source of the LED light bar 142 from leaking out, so as to increase the efficiency of light use.

Please refer to FIG. 3B and FIG. 4 together. The LED light bar 142 of this embodiment is preferably ring-shaped and arranged on the outer periphery of the light guide plate 144. The side of the LED light bar 142 facing the light guide plate 144 also includes A plurality of first LEDs 143 and a plurality of second LEDs 145 , each first LED 143 and each second LED 145 are spaced apart from each other and arranged in a staggered ring on the LED light bar 142 . In the embodiment shown in Figure 4, the color temperature of each first LED143 is lower than the color temperature of each second LED145, specifically, the color temperature of each first LED143 is between 2000K and 6500K, and the color temperature of each second LED145 Between 2000K and 6500K, the color temperature of each first LED is lower than that of each second LED, wherein each first LED 143 is, for example, yellow, and each second LED 145 is, for example, white.

The LED light bar 142 of this embodiment adopts the first LED 143 and the second LED 145 with two color temperatures to be arranged alternately. The pitch of the yellow LEDs is small, less likely to produce dark areas. When both the first LED 143 and the second LED 145 emit light (both the two-color LEDs emit light), the mixed light is relatively uniform, and no obvious single-color white light or yellow light can be seen, thereby achieving better adjustment of color temperature and/or brightness lighting effects. Conversely, when the LED light bar 142 adopts two colors and at least two LEDs of the same color are adjacently arranged, the LEDs only emit monochromatic light, for example, only the yellow light of each first LED 143, because the distance between any two adjacent yellow LEDs become larger, compared with the LED light bar 142 which adopts a single LED staggered arrangement, an obvious dark area will be produced. When both the first LED 143 and the second LED 145 emit light (both the two-color LEDs emit light), the mixed light is relatively uneven, and a gradient of yellow/light yellow/white can be seen. Therefore, when the distance between LEDs of the same color is larger and more LEDs are spaced apart, the above-mentioned gradient defects will be more obvious.

In the embodiment shown in FIGS. 1 and 2 , multiple sets of rotating shaft structures 160 are included, and each rotating shaft structure 160 is respectively connected between the lamp head 120 and the light pole 150 and between the light pole 150 and the base 110 .
