[0033] Figures 1 to 7 Fig. shows a lamp 101 according to an embodiment of the present utility model. The lamp 101 includes a fixed base 105, a light source 115, a lens 109, and a movable ring 104. The light source 115 is fixed within the fixed base 105, and the light-emitting surface of the light source 115 faces the lens 109. The light rays emitted from the light-emitting surface can pass through the lens 109 and be emitted outward. The lens 109 can be a Fresnel lens or other types of lenses 109. When the lens 109 is provided as a Fresnel lens, the lens 109 includes a spiral surface, and the spiral surface includes a plurality of concentric annular protrusions, and the spiral surface faces away from the light source 115. The lens 109 is fixedly connected to the movable ring 104, and the movable ring 104 can move relative to the fixed base 105.

[0034] As Figure 3 shown, the lamp 101 includes a circuit board assembly 114. The circuit board assembly 114 can include a single PCB (Printed Circuit Board) or multiple mutually fixed PCBs. The light source 115 is part of the circuit board assembly 114, and the light source 115 is mounted on one of the PCBs. The light source 115 can be an LED chip.

[0035] Please refer to Figure 1 and Figure 3 , in this embodiment, the fixed base 105 includes a radiator 117, an inner cylinder 116, a mounting shell 111, and a screw lamp socket 107. As Figure 4 shown, the mounting shell 111 is disposed inside the radiator 117, and the mounting shell 111 is fixed to the radiator 117 by a threaded connection. The inner cylinder 116 is sleeved outside the mounting shell 111, and the inner cylinder 116 is also located inside the radiator 117. The inner cylinder 116 and the mounting shell 111 can be fixed by screws. The rear end of the radiator 117 is fixedly connected to the screw lamp socket 107. The circuit board assembly 114 is electrically connected to the screw lamp socket 107. For example, the two are electrically connected through a wire (not shown). The screw lamp socket 107 can be connected to an external screw lamp base, so that an external power supply supplies power to the light source 115 through the screw lamp base. The specific model of the screw lamp socket 107 can be E27, E26, B22, etc. As Figure 4As shown, the mounting shell 111 and the radiator 117 jointly enclose a cavity 131, and the circuit board assembly 114 is installed in this cavity 131. The circuit board assembly 114 can be connected to the mounting shell 111 and / or the radiator 117 by screws. In this way, the light source 115 can be located within the fixed seat 105. The radiator 117 includes a plurality of heat sinks 106, and the radiator 117 can dissipate heat from the circuit board assembly 114 to prevent the temperature of the circuit board assembly 114 from being too high.

[0036] As Figure 4 shown, the movable ring 104 is sleeved outside the inner cylinder 116, and the radiator 117 is sleeved outside the inner cylinder 116 and outside the movable ring 104. That is, in the radial direction of the movable ring 104, the movable ring 104 is located between the inner cylinder 116 and the radiator 117. The lens 109 is fixedly connected to the movable ring 104. The lens 109 can be arranged inside the movable ring 104, and the lens 109 and the movable ring 104 can be fixed by means such as screwing, clamping, and bonding.

[0037] The movable ring 104 includes a slider 119, and the fixed seat 105 includes a chute 122. The slider 119 is slidably arranged in the chute 122, so that the movable ring 104 can move relative to the fixed seat 105. Specifically, please refer to Figure 5 , the movable ring 104 includes a main body 118 and a slider 119. The main body 118 is annular, and the slider 119 is connected to the inner peripheral surface of the main body 118. And, in order to reduce the resistance when the slider 119 slides, the slider 119 can be cylindrical. The chute 122 is located on the inner cylinder 116 of the fixed seat 105. The two ends of the chute 122 are spaced in the circumferential direction of the movable ring 104 and also spaced in the axial direction of the movable ring 104 (i.e., the front-back direction in the drawing). That is, the chute 122 is inclined with respect to the axis of the movable ring 104. In this way, when the movable ring 104 rotates relative to the fixed seat 105, the slider 119 slides along the chute 122, and the movable ring 104 will also move relative to the fixed seat 105 in the axial direction of the movable ring 104. Accordingly, the distance between the lens 109 fixed in the movable ring 104 and the light source 115 fixed in the fixed seat 105 will change, thereby changing the beam angle of the lamp 101. For example, taking Figure 5For example, when the movable ring 104 rotates clockwise (observed from the back to the front) relative to the inner cylinder 116 of the fixed base 105, the movable ring 104 will move forward, and the distance between the lens 109 and the light source 115 increases; conversely, when the movable ring 104 rotates counterclockwise (observed from the back to the front) relative to the inner cylinder 116 of the fixed base 105, the movable ring 104 will move backward, and the distance between the lens 109 and the light source 115 increases. Generally speaking, the greater the distance between the lens 109 and the light source 115, the longer the length of the optical path in the lamp 101, and the smaller the beam angle. The distance between the lens 109 and the light source 115 refers to the distance between the two in the axial direction of the lens 109.

[0038] The prior art uses a motor and a lead screw to drive the movement of the housing where the lens 109 is installed, thereby changing the beam angle. This design has problems such as complex structure and high cost. However, the present utility model does not use a motor and a lead screw. A slider 119 and a chute 122 are respectively provided on the movable ring 104 and the fixed base 105 of the present utility model. The user only needs to rotate the movable ring 104 where the lens 109 is installed to change the beam angle of the lamp 101. The adjustability of the beam angle of the lamp 101 of the present utility model is relatively high, and the structure for adjusting the beam angle in the lamp 101 is relatively simple and the cost is relatively low. In some embodiments, the adjustment range of the beam angle can be set to 15° - 50°.

[0039] As Figure 5 shown, in this embodiment, the slider 119 is provided on the movable ring 104, and the chute 122 is provided on the inner cylinder 116 of the fixed base 105. In some other embodiments not shown, the slider 119 can also be provided on the inner cylinder 116, and the chute 122 is provided on the movable ring 104. Or, in some other embodiments not shown, the slider 119 is provided on the movable ring 104, and the chute 122 is provided on the inner surface of the radiator 117. Or, in some other embodiments not shown, the slider 119 is provided on the inner surface of the radiator 117, and the chute 122 is provided on the movable ring 104. The feasible setting methods are not listed one by one here. As long as the slider 119 and the chute 122 are respectively provided on the movable ring 104 and the fixed base 105, and the chute 122 is inclined, the function of adjusting the beam angle can be achieved.

[0040] As Figure 5 shown, in this embodiment, three sliders 119 and three chutes 122 are provided, which is beneficial to improving the stability when the movable ring 104 rotates. However, the number of the sliders 119 and the chutes 122 is not strictly limited. For example, in some other embodiments, in order to reduce the processing difficulty of the inner cylinder 116 and the movable ring 104, the number of the sliders 119 and the chutes 122 can both be set to one.

[0041] In addition, in the embodiments described above, the fixing base 105 includes an inner cylinder 116, a mounting shell 111, a radiator 117, and a threaded lamp socket 107. In some other embodiments not shown, the number of components included in the fixing base 105 can be appropriately reduced. For example, the inner cylinder 116 and the mounting shell 111 can be combined as one part; for another example, the threaded lamp socket 107 can be omitted; for yet another example, when the power of the lamp 101 is relatively low, the radiator 117 can also be omitted.

[0042] As Figure 4 shown, in some embodiments, the lamp 101 further includes a light guide column 113. The light guide column 113 is made of a light-transmitting material, and the light-transmitting material can be glass, transparent plastic, etc. The light guide column 113 is used to transmit light from the light source 115 to another position with less loss, and the light mainly relies on total internal reflection to transmit within the light guide column 113. The material of the light guide column 113 can be acrylic resin, polycarbonate, epoxy resin, glass, etc. The material of the light guide column 113 can be selected as a material with a high light transmittance. For example, the light transmittance of the material can be greater than 90%. The light guide column 113 is fixed within the fixing base 105. More specifically, the light guide column 113 is located inside the mounting shell 111. The light guide column 113 is located between the light-emitting surface of the light source 115 and the lens 109. The light emitted by the light source 115 first passes through the light guide column 113 and then passes through the lens 109. The light guide column 113 is used to guide the light to the lens 109, so as to ensure that sufficient light can pass through the lens 109 and be emitted. As Figure 3 and Figure 4 shown, the lamp 101 further includes a light-shielding sleeve 112. The light-shielding sleeve 112 is made of a light-impermeable material (such as black plastic, black rubber, etc.). The light-shielding sleeve 112 is sleeved outside the light guide column 113, and both ends of the light-shielding sleeve 112 are connected to the circuit board assembly 114. The light-shielding sleeve 112 can reduce the loss of light, thereby increasing the illumination intensity of the light emitted from the lens 109.

[0043] As Figure 3 and Figure 4 shown, in some embodiments, the lamp 101 further includes a glass sheet 110. The glass sheet 110 is snap-fitted to the front end of the mounting shell 111, and the glass sheet 110 is located between the lens 109 and the light guide column 113. In some embodiments, the glass sheet 110 can be set as a filter, and the filter is used to filter out light of a specific wavelength. In some other embodiments, a specific pattern can be provided on the glass sheet 110, and the corresponding pattern can be displayed after the light is emitted from the lens 109.

[0044] As Figure 1 and Figure 3As shown, in some embodiments, the lamp 101 further includes a light shield 103. The light shield 103 is detachably connected to one end of the movable ring 104 away from the light source 115, and the light shield 103 is disposed around the lens 109. The light shield 103 can be set in a cylindrical shape and is made of light-impermeable material. The connection manner between the light shield 103 and the movable ring 104 can be set as snap connection, screw connection, magnetic attraction connection, etc. The light shield 103 can make the light emitted by the lamp 101 more concentrated, and the beam angle of the lamp 101 can also be changed by removing or installing the light shield 103. In addition, in some embodiments, in order to enable the lamp 101 to have a specific light-emitting effect, the lamp 101 can further include a grille 102 (such as Figure 1 shown), and the grille 102 is fixed inside the light shield 103. The cells of the grille 102 are hexagonal, and the grille 102 is in a honeycomb shape.

[0045] In the case where the light shield 103 is snap-connected to the lens 109, the snap connection structure provided on the movable ring 104 is as shown in Figure 6 and Figure 7 shown. As shown in Figure 6 In some embodiments, the movable ring 104 further includes an annular connecting portion, and the connecting portion is connected to one end of the main body 118. As shown in Figure 7 shown, the connecting portion includes an end face 127 and a first outer peripheral face 128. The end face 127 is located at one end of the connecting portion away from the light source 115 (i.e., the end face 127 is located at the front end of the connecting portion), and the first outer peripheral face 128 surrounds the end face 127. The first outer peripheral face 128 is provided with a snap groove 124, the snap groove 124 is in an L shape, and the snap groove 124 includes an axial section 125 and a circumferential section 126. The axial section 125 extends along the axial direction of the movable ring 104, and the circumferential section 126 extends along the circumferential direction of the movable ring 104. The light shield 103 further includes a snap (not shown). One end of the axial section 125 extends to the end face 127 so as to form an opening 132 on the end face 127 through which the snap can pass. The other end of the axial section 125 is communicated with one end of the circumferential section 126, and the snap can slide in the axial section 125 and the circumferential section 126.

[0046] When installing the light shield 103, the user can move the light shield 103 from front to back, so that the snap enters the axial section 125 from front to back; after the snap moves to the rear end of the axial section 125, the user can rotate the light shield 103 in the clockwise direction (viewing angle from front to back) to make the snap enter the circumferential section 126, so as to realize the snap connection between the light shield 103 and the lens 109. On the contrary, when the user needs to remove the installation cover, the user can first rotate the light shield 103 counterclockwise to make the snap move to the rear end of the axial section 125, and then pull out the light shield 103 from back to front.

[0047] As shown in Figure 7As shown, in some embodiments, the main body 118 includes a limiting surface 129, and the limiting surface 129 is located at one end of the main body 118 away from the light source 115 (i.e., the front end of the main body 118). The connecting portion is connected to the limiting surface 129 and protrudes relative to the limiting surface 129. The limiting surface 129 is used to limit the forward movement of the light shield 103, facilitating the user to install the light shield 103.

[0048] As Figure 5 shown, in some embodiments, the movable ring 104 further includes a plurality of anti-slip protrusions 121, the main body 118 includes a second outer peripheral surface 130, the anti-slip protrusions 121 are connected to the second outer peripheral surface 130 and protrude relative to the second outer peripheral surface 130, and the plurality of anti-slip protrusions 121 are distributed along the circumferential direction of the movable ring 104. When the user rotates the movable ring 104, the user's fingers or palm can contact the anti-slip protrusions 121, thereby screwing the movable ring 104. The anti-slip protrusions 121 are beneficial to reducing the risk of slipping between the user's hand and the movable ring 104, thereby facilitating the user to adjust the beam angle of the lamp 101.

[0049] As Figure 5 shown, in some embodiments, in order to facilitate the user to accurately adjust the beam angle, the second outer peripheral surface 130 is further provided with a beam angle scale 120. As the position of the movable ring 104 changes, the portion of the beam angle scale 120 exposed outside the radiator 117 will also change. The user can determine the current beam angle of the lamp 101 through the exposed portion of the beam angle scale 120, so as to judge whether the beam angle of the lamp 101 has been adjusted to the required angle.

[0050] As Figure 1 shown, in some embodiments, the lamp 101 further includes a socket 108, and the socket 108 is electrically connected to the light source 115 of the circuit board assembly 114. The socket 108 is fixedly connected to the radiator 117 and exposed outside the radiator 117. The socket 108 can be inserted into the plug 201 (as Figure 2 shown), so that the external power supply supplies power to the light source 115 through the cable 202 and the plug 201. Since the lamp 101 is provided with both the socket 108 and the screw lamp socket 107 at the same time, the lamp 101 has more electrical connection methods with the external power supply, the use flexibility of the lamp 101 is higher, and the lamp 101 can be applied to more scenarios.

[0051] As Figure 8 shown, the present utility model further provides an illumination device 300, and the illumination device 300 includes a box body 301, a power module, and the lamp 101 mentioned above ( Figure 8 only one lamp 101 is shown). As Figure 8As shown, the box body 301 includes a plurality of grooves 303, and each groove 303 is used to accommodate a lamp 101. The power supply module is not shown. The power supply module is installed in the box body 301. When the lamp 101 is set in the groove 303, the lamp 101 is electrically connected to the power supply module. The power supply module can be a storage battery or a rechargeable battery. It can be that the power supply module is connected to the above-mentioned lamp 101 through a connecting wire, and the power supply module supplies power to all the lamps 101 placed in the smart device 100. In this way, it is not necessary to add a battery to each lamp 101, thus providing conditions for configuring parameters for all the lamps 101 simultaneously.

[0052] In addition, the lamp 101 can be removed from the groove 303, and the user can adjust the number of lamps 101 installed in the box body 301 according to the lighting brightness or other requirements. The lighting device 300 further includes a control component 306. The control component 306 is installed on the box body 301. The control component 306 can be communicatively connected to the lamp 101 in the groove 303, and the control component 306 can control the working state of the lamp 101. The control component 306 can include a number of buttons and a display screen. The display screen can display the status information of the lighting device 300 or the lamp 101. The user can change the state of the lamp 101 by pressing the button. For example, change the color of the light emitted by the lamp 101, turn on or off the lamp 101, etc. That is, the box body 301 can accommodate a plurality of lamps 101 at the same time, so that the control component 306 can control a plurality of lamps 101 at the same time and configure parameters for a plurality of lamps 101 at the same time, including being able to configure addresses for a plurality of lamps 101 at the same time. This solves the problem that only one lamp can be parameter - set at a time in current large - scale activities, thus reducing the time for lamp parameter configuration and improving the efficiency of lamp parameter configuration.

[0053] As described above, the lamp 101 can include a screw lamp socket 107 and a socket 108. In order to electrically connect the lamp 101 to the power supply module in the box body 301, the lighting device 300 can further include a plug 201 for plugging into the socket 108. There is one plug 201 in each groove 303, and the plug 201 is connected to the power supply module through a cable 202. Or, each groove 303 includes an interface for cooperating with the screw lamp socket 107.

[0054] As Figure 8 shown, the groove 303 includes a central area 304 and two peripheral areas 305. The peripheral areas 305 and the central area 304 are in communication with each other, and the peripheral areas 305 protrude outward relative to the edge of the central area 304. The central area 304 is used to accommodate the lamp 101, and the peripheral areas 305 allow the user's fingers to reach in so that the user can take out the lamp 101 from the groove 303. In order to prevent the lamp 101 from being damaged, elastic materials such as rubber and foam can be provided in the wall surface of the groove 303.

[0055] In some embodiments, the lighting device 300 further includes an infrared emitter (not shown), and each groove 303 may be provided with one or more infrared emitters. The lamp 101 includes an infrared receiver (not shown), and the infrared receiver is integrated in the circuit board assembly 114 and is exposed outside the fixing base 105. The infrared emitter may be disposed in the central region 304 of the groove 303 to prevent the fingers extending into the peripheral region 305 from affecting the detection accuracy of the detection unit. Also, rubber or foam on the wall surface of the groove 303 should not block the infrared emitter. The infrared emitter can emit an infrared signal. After the lamp 101 is correctly placed in the groove 303, the infrared receiver can receive the above infrared signal. After the infrared receiver receives the infrared signal, the second communication module of the lamp 101 starts to attempt to establish a wireless communication connection with the first wireless communication module. The lighting device 300 further includes an indicator lamp 302, and the indicator lamp 302 is installed on the surface of the box body 301 and is disposed adjacent to the groove 303. When the lamp 101 in a certain groove 303 and the control component 306 achieve a communication connection, the indicator lamp 302 corresponding to the groove 303 will be constantly on, thereby prompting the user that the lamp 101 has been in communication connection with the control component 306. Subsequently, the user can control the operation of the lamp 101 through the control component 306. The first wireless communication module may include at least one of a Bluetooth module, a DMX module, a CRMX module, a UHF module, and a 2.4G WiFi module; the second wireless communication module may include at least one of a Bluetooth module, a DMX module, a CRMX module, a UHF module, and a 2.4G WiFi module. The user can also control the lighting device 300 through a mobile phone, a tablet computer, or other electronic devices. For example, the user can first establish communication between the mobile phone and the control component 306, and then send a control instruction to the lighting device 300 through the mobile phone.
