Detailed Description

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present utility model. The appearances of the same phrase in various places in the specification are not necessarily limited to the same embodiment, but are understood to be independent of other embodiments or alternative embodiments. Given the teachings of the embodiments disclosed in this disclosure, one of ordinary skill in the pertinent art will recognize that the embodiments described in this disclosure may have other technical combinations or variations consistent with the inventive concepts.

Fig. 1 and 2 are perspective and exploded views of a touch lamp with dimming function. As shown in the drawing, the present embodiment provides a touch lamp 100 with dimming function, which includes a base 110, a lamp cap 120, a lamp post 150, and a touch module 130.

Referring to fig. 3A, the lamp cap 120 includes a light emitting module 140. The two ends of the lamp pole 150 are respectively connected with the base and the lamp cap 120. Specifically, the lamp pole 150 further includes a first rod 151 and a second rod 152 connected to the first rod 151, wherein the first rod 151 can rotate relative to the second rod 152. The touch module 130 is selectively disposed in the base 110, the lamp cap 120 or the lamp post 150, and is electrically connected to the light emitting module 140 to provide color temperature and/or brightness adjustment for the light emitting module 140.

In the following, the light emitting module 140 is mounted on the lamp base 120 as shown in fig. 1, 2 and 3A, and the light emitting module 140 includes an LED strip 142, a light guide plate 144, a reflective sheet 146 and a diffusion sheet 148. The reflecting sheet 146 and the diffusing sheet 148 are respectively disposed on two opposite side surfaces of the light guide plate 144, and 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 may be elliptical, 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 light, so that the light emission and color formation of the LED light bar 142 can be more uniform. The Diffuser 148 (Diffuser) may be used to make the light distribution more uniform, and a Prism sheet (Prism/lens sheet) with a condensing function may be added to the Diffuser 148 to increase the directivity of the emitted light, so as to achieve the purpose of improving the front brightness. The Reflector 146 reflects the light leaking 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 light utilization efficiency.

Referring to fig. 3B and fig. 4 together, the LED light bar 142 of the present embodiment is preferably annular and disposed on the outer periphery of the light guide plate 144, and a side surface of the LED light bar 142 facing the light guide plate 144 further includes a plurality of first LEDs 143 and a plurality of second LEDs 145, wherein each first LED143 and each second LED145 are disposed on the LED light bar 142 in a staggered manner and spaced apart from each other. In the embodiment shown in fig. 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, the color temperature of each second LED145 is between 2000K and 6500K, the color temperature of each first LED is lower than the color temperature of each second LED, wherein each first LED143 is, for example, yellow, and each second LED145 is, for example, white.

The LED light bars 142 of the present embodiment adopt the first LEDs 143 and the second LEDs 145 with dual color temperatures to be staggered, and when the LED light bars 142 emit only monochromatic light, for example, only yellow light of each first LED143 is emitted, and due to the small interval between any two yellow LEDs, dark areas are less generated. When the first LED143 and the second LED145 both emit light (both the two-color LED emit light), the light mixing is uniform, and no obvious white light or yellow light of a single color is visible, so that a better lighting effect of adjusting color temperature and/or brightness is achieved. In contrast, when the LED light bars 142 are two-color LEDs and at least two adjacent LEDs are arranged in the same color, the LEDs emit only a single color, for example, only yellow light of each first LED143, and as the interval between any two adjacent yellow LEDs is increased, a distinct dark area is generated in comparison with the LED light bars 142 that are staggered with respect to the single LEDs. When both the first LED143 and the second LED145 emit light (both the two-color LEDs emit light), the light mixing is less uniform, and a yellow/yellowish/white gradient is seen. Thus, the above-described gradient defect may be more pronounced as the same color LEDs are more spaced apart.

In the embodiment shown in fig. 1 and 2, a plurality of sets of rotating shaft structures 160 are further included, and each rotating shaft structure 160 is respectively connected between the lamp cap 120 and the lamp post 150 and between the lamp post 150 and the base 110. Specifically, each of the shaft structures 160 is respectively connected between the first rod 151 and the lamp cap 120, between the first rod 151 and the second rod 152, and between the second rod 152 and the base 110, so that the lamp cap 120 can rotate relative to the first rod 151, the first rod 151 can rotate relative to the second rod 152, and the second rod 152 can rotate relative to the base 110, thereby adjusting to a suitable angle or direction.

In the embodiment shown in fig. 2, each of the shaft structures 160 includes a first rotor 162, a second rotor 164, a bolt assembly 166, and at least one set screw 168. The bolt assembly 166 is, for example, a combination of a bolt and a screw, and is respectively connected to the first rotator 162 and the second rotator 164 in a penetrating manner, so that the bolt assembly 166 becomes the axial center rotation of the first rotator 162 and the second rotator 164. The at least one set screw 168 passes through the light pole 150 to securely engage the first swivel 162 or the second swivel 164. The above-mentioned rotating shaft structure 160 is a prior art, and will not be described in detail herein.

In the embodiment shown in fig. 4, the lamp cap 120 further includes a housing 122, and the housing 122 is provided with an opening (not shown) to expose the touch module 130. The touch module 130 includes a touch interface 126 and a touch pad 124, the touch interface 126 is exposed to the housing 122, and the touch pad 124 is disposed under the touch interface 126. When the touch module 130 is disposed on the lamp cap 120, the touch module 130 is disposed on the light emitting module 140. The touch interface 126 is made of acrylic material, for example, and is glued to the touch control board 124 to form a touch module 130. The touch interface 126 is disposed on the touch control board 124 and exposed to the housing 122 for touch operation by a user. Touch control board 124 is secured within housing 122 of lighthead 120, such as by screws (not shown) or other suitable elements. When the touch interface 126 is touched, the touch signal is transmitted to the touch control board 124, thereby controlling the adjustment of the color temperature and/or brightness of the LED light bar 142. Specifically, the touch control board 124 is electrically connected to the electrical contact portion 149 of the LED light bar 142 through a cable (not shown) to control the on/off operations thereof.

As described further below, when touch interface 126 is touched, the touch signal is conducted to touch pad 124, and after touch pad 124 senses a touch event, touch pad 124 analyzes the length and direction of the touch and adjusts the color temperature and/or brightness. In a specific embodiment, the LED light bars 142 of the light emitting module 140 can be turned on/off when any point of the touch interface 126 is touched.

Assume that the extension line of the lamp pole 150 is in the Y-axis direction and perpendicular to the Y-axis direction is in the X-axis direction. Let X be the color temperature and Y be the brightness, each group (X, Y) corresponds to a group of color temperature and brightness combinations, when any point on the touch interface 126 is pressed, the color temperature and/or brightness of the light emitting module 140 can be adjusted and controlled. Specifically, when sliding vertically, the brightness may be adjusted, +Y-dimming, -Y-dimming. When sliding horizontally, the color temperature can be adjusted, +X adjusts the color temperature upwards, -Y adjusts the color temperature downwards. When any point of the touch interface 126 is pressed, the position is arbitrarily moved, and the color temperature and/or brightness are immediately adjusted. The light irradiation range can be adjusted by pinching or expanding the touch interface 130 with two fingers, wherein pinching (shrinking) and expanding (enlarging) are performed. Alternatively, the current color temperature and/or brightness (power down still) may be remembered by holding down at the center of the touch interface 126 for at least 2 seconds. At two points at the center of the touch interface 126, the color temperature and/or brightness in the memory can be adjusted. The touch actions and operation modes described above are merely illustrative, and are not limited to the present utility model.

Fig. 5 and fig. 6 are schematic perspective views of a second embodiment and a third embodiment of the touch lamp with dimming function, in which the touch module 130 is respectively disposed on the base 110 and the light pole 150. The touch module 130 may be selectively disposed on the first bar 151 or the second bar 152, but is not limited thereto. The touch module 130 disposed on the base 110 or the lamp pole 150 can be electrically connected to the light emitting module 140 of the lamp cap 120 through cables (not shown). The light pole 150 or the base 110 is provided with an opening (not shown) to expose the touch interface 126. After the user touches the touch interface 126 with a finger, the touch panel 124 can adjust and control the color temperature and/or brightness of the light emitting module 140 after sensing the touch. Regarding the structure of the light emitting module 140, the connection relationship between the elements, and the touch operation and the operation manner of the touch module 130, please refer to the above embodiments, and the description is omitted herein.

In summary, the touch lamp 100 with dimming function of the present embodiment adopts the dual-color temperature LED light bar 142, which includes the plurality of first LEDs 143 and the plurality of second LEDs 145 that are staggered with each other, and when the LED light bar 142 emits only monochromatic light, for example, only yellow light of each first LED143 is emitted, and no dark space is generated due to the small distance between any two yellow LEDs. When the first LED143 and the second LED145 emit light (both the two-color LED emit light), the light mixing is relatively uniform, and no obvious white light or yellow light with a single color can be seen, so that a better and excellent lighting effect of adjusting color temperature and/or brightness can be achieved, and the control is simpler and more convenient, and accords with the use habit of modern people.
