It is favored for its high light focusing ability and adjustable beam angle. However, the traditional PAR lamp is usually limited to brightness adjustment, and has limited adjustment capability for color temperature and illumination angle.

[0003] In the prior art, lamps with adjustable light, adjustable color temperature and adjustable angle have appeared, but they usually exist as independent functions, and users need to choose different types of lamps to meet specific use scenarios according to needs.

[0004] A dual-color temperature lens is known, which integrates two lens regions of different color temperatures on the same lens body: a first lens corresponding to a first color temperature, and a second lens corresponding to a second color temperature. This structure can realize two different angles of two different color temperatures to meet the lighting needs. However, this structure has the following problems: first, the color temperature and the angle are paired, and each color temperature lens is designed for a fixed angle, so the color temperature and the angle are bound, which limits the independent adjustment capability of the illumination angle and reduces the flexibility of application; second, due to the pairing relationship between the color temperature and the angle, the user cannot independently select the required color temperature and illumination angle, which may not meet the needs in situations that require fine adjustment of the lighting environment; third, the design of the dual-color temperature lens may limit the possibility of realizing more diversified adjustment functions.

[0038] Reference Figures 1-6 The present embodiment provides a PAR lamp with adjustable color temperature and angle, which mainly comprises a lamp shell body 1, a power component 2 mounted on the lamp shell body 1, an LED light source component 3, a lens, a lamp holder 4 and the like.

[0039] The lamp shell body 1 serves as a housing, which is usually made of metal or high-quality plastic material, and has the functions of protecting internal components, heat dissipation and fixing structure. Its heat dissipation function can be improved by adding heat dissipation fins inside the lamp shell body 1. The power component 2 is responsible for converting the input alternating current into direct current required by the LED light source, and may contain safety features such as overheat protection and short circuit protection. The lens is installed in front of the LED light source component, which is used to focus and shape the light, produce the required beam angle and distribution, and the lens serves as the initial illumination angle setting of the LED light source component. The lamp holder 4 is the part of the PAR lamp connected to the power supply, and the common types of lamp holder 4 include GU10, E27 and the like, which ensures the electrical compatibility and safety of the lamp.

[0040] In this embodiment, the provided LED light source assembly 3 includes two sets of lamps mounted on the light source board, and the two sets of lamp beads 5 are electrically connected to the power supply assembly 2. The two sets of lamp beads 5 emit two different color temperatures of light, for example, one set emits warm light and the other emits cool light.

[0041] A resistor is installed on the circuit connecting the power supply component 2 to the LED beads 5, and the output current of the LED beads 5 is controlled by the resistor. The brightness of the LED beads 5 can be controlled by controlling the current. A set of resistors is set for each group of LED beads 5; each set of resistors controls the output current of each group of LED beads 5. The desired color temperature can be achieved by mixing the different output currents of the two groups of LED beads 5. Color temperature adjustment is achieved by adjusting the current of each group of LED beads 5, which controls their brightness. Different color temperatures can be achieved by adjusting the ratio of the brightness of the two groups of LED beads 5. For example, if a neutral or slightly warm color temperature is needed, the current of the warm-colored LED beads 5 can be increased while the current of the cool-colored LED beads 5 can be decreased. Conversely, if a cooler color temperature is needed, the current of the cool-colored LED beads 5 can be increased.

[0042] The resistor is set as a variable resistance resistor, which allows for finer current control and precise adjustment of color temperature. To further control the color temperature, this embodiment includes an adjustment switch 6 connected to the resistor on the lamp housing body 1. This adjustment switch 6 is a toggle switch. The toggle switch controls the resistor to achieve current control. By selecting different resistance values, the total resistance in the circuit is changed, thereby controlling the current flowing through the resistor. Using a toggle switch to adjust the resistor for current control is a simple, economical, and effective method suitable for various applications requiring manual adjustment of power or brightness.

[0043] In this embodiment, a resistor is used in conjunction with a toggle switch. The color temperature of the light source is adjusted by toggling the toggle switch on the main body, enabling switching between multiple color temperatures. Users can easily switch the color temperature of the LED light by toggling the switch, flexibly controlling the brightness and color temperature of the two sets of LED beads 5 to create ideal lighting effects. This provides a high degree of flexibility and personalization for lighting design. Generally, LED lights are set to a color temperature of 3 CCT or 5 CCT, corresponding to a toggle switch with 3 or 5 settings.

[0044] In this embodiment, the lamp housing body 1 is provided with a circular lamp disk 11 for assembling the lampshade 7, and an optical lens with different textures 10 is provided on the lamp housing body 1. The optical lens structure is set as a lampshade 7 type lens structure. The lamp housing body 1 and the lampshade 7, as well as the lamp housing body 1 and the optical lens, are detachably connected by rotating buckles. After the lampshade 7 is disassembled, the optical lens can be installed. The optical lens can be used as the lampshade 7 and can also realize the adjustment of the illumination angle of the lamp beads 5.

[0045] The detachable connection structure is that the circular lamp disc 11 is provided with a clamping groove 12 and a rotating groove 13 along the inner side, the clamping groove 12 is communicated with the rotating groove 13, and the lampshade 7 and the optical lens are provided with four protrusions 14 along the edges. Specifically, the clamping groove 12 is arranged along the axial direction, the rotating groove 13 is arranged along the circumferential direction, and four sets of clamping grooves 12 and rotating grooves 13 are distributed along the circumferential direction on the circular lamp disc 11; and the lampshade 7 and the optical lens are correspondingly provided with the four protrusions 14 along the edges.

[0046] During installation, the protrusion 14 is inserted into the rotating groove 13 from the clamping groove 12, and is rotated along the rotating groove 13 to be clamped at one end of the rotating groove 13 away from the clamping groove 12, so that the rotating clamping connection is formed. During disassembly, the protrusion 14 is only needed to be reversely rotated to the position corresponding to the clamping groove 12, so that the protrusion 14 is separated from the circular lamp disc 11 through the clamping groove 12.

[0047] In order to realize multi-angle adjustment, in the embodiment, the optical lens at least includes a first lens 8 and a second lens 9, the first lens 8 and the second lens 9 are lenses with different sizes of textures 10, and the texture 10 of the lens is composed of a series of small convex lenses.

[0048] The special texture 10 on the first lens 8 and the second lens 9 can change the direction and distribution of light, and the special texture 10 is equivalent to a small convex lens. The special texture 10 is composed of a series of small protrusions 14 or depressions, and the structure is similar to a plurality of small convex lenses in a microscopic scale. Each microstructure can affect the light passing through the surface. Due to different angles of incidence of light, the focusing or defocusing effect of light changes with the change of the size of the texture 10, so that the illumination angle is changed.

[0049] The lamp bead 5 sets the initial illumination angle to 25° under the action of the lens. When the angle of the PAR lamp needs to be adjusted to 40°, the lampshade 7 is disassembled, and the first lens 8 is correspondingly installed. By covering the first lens 8 with special treatment and texture on the basis of the lens, the light is scattered to increase the angle to 40°. When the angle of the PAR lamp needs to be adjusted to 60°, the lampshade 7 or the first lens 8 is disassembled, and the second lens 9 is correspondingly installed. By covering the second lens 9 with special treatment and texture on the basis of the lens, the light is scattered to increase the angle to 60°.

[0050] More optical lenses with special treatment and texture can be configured to realize the adjustment of the illumination angle at any angle within 40°-60°, and improve the flexibility and accuracy of the adjustment.

[0051] In this embodiment, the change of the light propagation direction is achieved by the superposition of the optical lens using the structure of the lampshade 7 based on the original lens technology, which is used to change the focusing characteristics of the light, expand or reduce the field of view, and change the incidence and emission angles of the light. The user can change the illumination angle by replacing the lampshade 7 instead of changing the lens, so as to achieve the required range of light irradiation.

[0052] The above description is only the preferred embodiment of the present application, but the design concept of the present application is not limited thereto. Any skilled person in the art can make non-essential changes to the present application within the scope of the disclosed technology, which is an infringement of the protection scope of the present application.
