Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a PWM dimming module with adjustable color temperature. Background Technology

[0002] The utility model application with application number 201620458144.6 discloses an LED dimming and color temperature adjustment circuit. The control unit outputs one PWM dimming signal and one PWM color temperature adjustment signal to control the dimming unit and the color temperature adjustment unit separately. Only one power supply is used for dimming, which avoids color temperature drift when using power supply to adjust color temperature, thereby improving the color temperature control performance of LED lights.

[0003] In actual use, it was found that the changes in color temperature and brightness at each stage were not obvious enough for the lamps to be used with this circuit. Users could hardly perceive the changes in color temperature and brightness. We tried to make the changes more obvious by modifying the structure of the lamp module and combining it with its own dimming and color temperature adjustment circuit. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an adjustable color temperature PWM dimming module. A rotatable windmill light is installed on the control box via an adjustment rod. The windmill light has several light-emitting blades. The user can rotate different light-emitting blades to connect with the adjustment rod to form an electrical circuit, thereby illuminating the light-emitting blades. Different light-emitting blades have different brightness and color temperature. Combined with the controller circuit that has dimming and temperature adjustment functions, the changes in light temperature and brightness are more obvious and easier for the user to observe. The adjustment rod has a steering function, which can drive the windmill light to adjust the lighting angle and height.

[0006] This utility model provides an adjustable color temperature PWM dimming module, including a control box with an internal PWM dimming and temperature control circuit, an adjustment rod rotatably connected to the side of the control box, and a rotating windmill light rotatably connected to the adjustment rod. The rotating windmill light includes a fixed shaft and multiple light-emitting blades arranged around the fixed shaft. Each light-emitting blade is provided with at least one set of yellow light bulbs and white light bulbs. The number of light bulbs in each light-emitting blade is different. A fixing post extends from the side of the adjustment rod, and a mating interface is provided in the fixing post. The fixed shaft is screwed to the mating interface.

[0007] The control box equipped with a PWM dimming and temperature control circuit is electrically connected to the rotating windmill lamp to form a light-emitting device and achieve the lighting effect. The PWM dimming and temperature control circuit realizes the dimming and temperature control function of the light in terms of circuit setting. In terms of hardware configuration, by setting multiple light-emitting blades with different numbers of light bulbs, the dimming and temperature control effect is enhanced, which makes it easier for users to observe the current color temperature and brightness of the light. The specific principle is that when the circuit outputs the same PWM signal conduction cycle, the brightness of the blade is increased or decreased by increasing or decreasing the number of light bulbs, and the color temperature is adjusted by increasing or decreasing the ratio of yellow and white light bulbs. A loop is formed between the rotatable light-emitting blades and the adjustment rod. Users can manually rotate different light-emitting blades to connect with the adjustment rod to light up the light-emitting blades to achieve lighting. Preferably, there are 4 light-emitting blades, which correspond to 4, 6, 8 and 12 light bulbs respectively, and the ratio of yellow and white light bulbs is 1:1.

[0008] In some embodiments, the fixed shaft ring includes a base, a limiting groove, and a screw interface. The screw interface has threads on its outer side and a receiving cavity on its inner side that communicates with the interior of the base. The screw interface with threads on its outer side is used to screw into the corresponding interface, fixing the position of the rotating windmill lamp and making the rotating windmill lamp removable and replaceable. The receiving cavity communicates with the corresponding interface to accommodate the power supply circuit.

[0009] In some embodiments, the light-emitting blade is connected to the side of the base, and the rear side of the base is connected to the screw interface via a rotary bearing. The limiting slots are arranged around the screw interface and connected to the base, and the number and position of the limiting slots correspond to the light-emitting blade. A top cover is provided on the front side of the base. After removing the top cover, the screw interface can be rotated through the base. When the screw interface is connected to the fixing post, the base and the light-emitting blade connected by the rotary bearing can rotate. The limiting slots at corresponding positions are used to abut against the limiting springs on the fixing post, thereby limiting the rotation of the light-emitting blade.

[0010] In some embodiments, the outer side of the limiting slot is arc-shaped and conforms to the outer ring curvature of the base. An opening is provided on the inner side of the limiting slot, and baffles are provided on both sides of the limiting slot, with the edges of the baffles inclined. The limiting slot with baffles and an opening is used to hold the limiting spring piece. When the user applies force, the limiting spring piece can quickly disengage from the current limiting slot and engage with the next limiting slot. The stopping sensation generated during rotation allows the user to determine whether the engagement is successful. The outer seal of the limiting slot controls the sliding direction of the limiting spring piece, ensuring it can only disengage from the inner opening.

[0011] In some embodiments, symmetrically extending limit springs are provided on the upper side of the fixing post, and both limit springs abut against the limit slot and are located between the two baffles. The limit springs provided on the upper side are used to fix the uppermost light-emitting blade, so that it can be connected to the magnetic base on the adjusting post to form a circuit and realize power-on light emission.

[0012] In some embodiments, a steering ball is provided at the bottom end of the adjusting rod, and two spherical grooves are vertically provided on the steering ball. The end of the adjusting rod is spherical and is engaged in one of the spherical grooves. A connecting rod extends from the side of the control box, and the end of the connecting rod is also spherical and is engaged in another spherical groove. The steering ball is used to connect the adjusting rod and the control box. The spherical end is engaged in the spherical groove, allowing the adjusting rod to rotate in any direction to adjust the lighting direction and angle of the rotating windmill lamp. For specific details regarding the structure of the steering ball controlling the rotation of the adjusting rod, please refer to the prior art.

[0013] In some embodiments, the adjusting rod is hollow and has a through hole on its bottom side, the connecting rod is hollow and communicates with the interior of the control box, and the end of the connecting rod also has the through hole. The through hole allows the conductive wiring inside the control box to remain unobstructed until it connects to the light bulb.

[0014] In some embodiments, the adjusting rod includes a primary rod and a secondary rod, the secondary rod being slidably connected to the primary rod. A fixing post is disposed on the primary rod, and a magnetic base is provided on the secondary rod. An adsorption plate is disposed at a corresponding position on the back side of the light-emitting blade, and the adsorption plate is attracted to the magnetic base. The slidable connection between the primary and secondary rods allows the height of the magnetic base on the secondary rod to be adjustable to accommodate different sizes of light-emitting blades. The adsorption plate on the light-emitting blade is made of metal and is attracted to the magnetic base, providing both electrical conductivity and positioning for the light-emitting blade.

[0015] In some embodiments, the PWM dimming and temperature control circuit includes a control unit, a dimming unit, a color temperature adjustment unit, and a power supply. The control unit is connected to the light-emitting bulb on the light-emitting leaf via the color temperature adjustment unit. The control unit is also connected to the dimming unit, and the dimming unit is connected in series with the power supply and the light-emitting bulb. The specific structure of the PWM dimming and temperature control circuit can be found in the background art documents, and will not be elaborated here. However, it should be understood that the technical solution of this application does not lack its essential technical features.

[0016] In some embodiments, the control box is equipped with a button electrically connected to the PWM dimming and temperature control circuit. The PWM dimming and temperature control circuit is connected to the light-emitting blade to form the positive terminal, and the magnetic base is connected to the PWM dimming and temperature control circuit to form the negative terminal. When the light-emitting blade is connected to the magnetic base, a power-on circuit is formed. The button, electrically connected to the PWM dimming and temperature control circuit, is used to adjust the color temperature and brightness in the circuit. When the light-emitting blade is connected to the magnetic base, a power-on circuit is formed; when disconnected, no circuit is formed. The specific circuit connection method of connecting the PWM dimming and temperature control circuit to the light-emitting blade to form the positive terminal and the magnetic base to the PWM dimming and temperature control circuit to form the negative terminal is well known to those skilled in the art and will not be described in detail here.
