Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting lamps, in particular to a lighting lamp with switchable spotlight and floodlight lamp holder structure. BACKGROUND

[0002] The lighting lamp is a device that converts electrical energy into light energy for providing light and dispelling darkness, and plays a key role in people's life and production. With the continuous upgrading of the lighting lamp, the spotlight and floodlight of the lighting lamp can be realized by changing the relative position of the light source. When the light source is close to the lampshade, the light is more concentrated after refraction, realizing spotlight. When the light source is away from the lampshade, the light refraction angle changes, and the light is dispersed to the four directions, achieving the effect of floodlight, thereby giving users different use experience.

[0003] Before use, the lighting lamp needs to be assembled. During the assembly process, due to non-standard operation, the force applied by the lampshade or the lamp holder will be unbalanced, causing the center axis between the lampshade and the lamp holder to be misaligned, and thus the light cannot be uniformly scattered or gathered according to the designed angle and direction, resulting in light deviation, uneven brightness, and affecting the lighting effect.

[0050] The principle and advantages of the lighting lamp with the light condensing and dispersing switchable lamp holder structure are as follows:

[0051] Installation of lighting fixtures:

[0052] In actual use, the operator aligns the lampshade 2 with the lamp holder 11. Initially, because the movable block 21124 on the movable rod 2112 is mounted on the movable rod 2112 via a rotating shaft 21123, and a torsion spring 21125 is mounted on the rotating shaft 21123, the movable block 21124 will deflect at a certain angle relative to the movable rod 2112 under the cooperation of the torsion spring 21125. Multiple movable blocks 21124 can form a "conical surface" with the movable rod 2112, and then the insertion rod 211 moves towards the insertion hole 213. The insertion hole 213 consists of a conical hole 143, a round hole, and a limiting hole (the angle of the conical surface is the same as the angle of the "conical surface" formed by the movable blocks 21124). When the plug rod 211 enters the plug hole 213, the movable block 21124 is squeezed by the conical surface, generating a force that pulls it towards the center. This causes the plug rod 211 to automatically adjust its position, making its axis as coincident as possible with the axis of the plug hole 213. As the plug rod 211 continues to move, the movable block 21124 will completely fit into the mounting groove 21122, forming a single unit with the movable rod 2112 (the diameter of the movable rod 2112 is the same as the diameter of the circular hole). When the movable rod 2112 moves to the position of the limiting hole, since the diameter of the limiting hole is smaller than that of the circular hole, the circular hole can prevent the movable rod 2112 from moving further, and the stroke of the movable rod 2112 ends.

[0053] It is worth noting that the "conical surface" structure plays a good guiding role during the insertion process. The "conical surface" formed by the movable block 21124 and the movable rod 2112 cooperates with the conical hole 143 in the insertion hole 213 to form a guide track, which allows the insertion rod 211 to be more accurately aligned with the center of the insertion hole 213, making it easier to insert and reducing deviation and misalignment during insertion. Furthermore, due to the shape characteristics of the conical surface, when the movable block 21124 of the plug rod 211 contacts the conical surface of the plug hole 213, a force is generated that moves towards the center, causing the plug rod 211 to automatically adjust its position so that its axis coincides with the central axis of the plug hole 213. This ensures the coaxiality of the two after connection. The central axes of multiple plug rods 211 coincide with the central axis of the corresponding plug hole 213, thereby enabling the central axis of the lampshade 2 to coincide with the central axis of the lamp holder 11. This achieves coaxial installation between the lampshade 2 and the lamp holder 11, preventing them from shifting during assembly and causing the lighting effect to deteriorate during later use.

[0054] Continue to push the lampshade 2 to move, under the cooperation of the fixed plate 21111, the sliding groove 21121 and the elastic piece, the fixed rod 2111 will drive the locking rod 21112 to continue to move to the position of the limiting hole, when the sealing gasket is attached to the surface of the lamp holder 11, the magnet 25 on the sealing gasket will be attracted to the lamp holder 11 at this time, realizing the preliminary fixation of the lampshade 2, and the locking hole 21113 on the locking rod 21112 will leak out a part of the plug-in hole 213. Then the operator pulls down the rotating ring 2142, so that the rotating ring 2142 will move downward along the guide plate 2143, until the limiting groove 2144 in the rotating ring 2142 will be separated from the limiting block 2145 on the circumferential outer surface of the lamp holder 11. At this time, rotate the rotating ring 2142 by a certain angle, the circular ring 2141 will rotate synchronously, and then the arc block 2146 on the circular ring 2141 will abut against the protrusion 2148 on the locking wedge block 2147 (the arc block 2146 is an outward convex arc).

[0055] With the movement of the arc block 2146, the locking wedge block 2147 is gradually increased by the extrusion of the arc block 2146, and then the locking wedge block 2147 will move to the locking hole 21113, until the locking wedge block 2147 is completely inserted into the locking hole 21113. When the locking wedge block 2147 moves to the locking hole 21113, because the locking hole 21113 is provided with a slope, the cooperation of the locking wedge block 2147 and the slope in the locking hole 21113 can provide a stable and larger locking force, when the locking wedge block 2147 is completely inserted into the locking hole 21113, the action of the slope will make the locking rod 21112 produce upward displacement, and then it will drive the lampshade 2 to produce a short distance displacement (the sealing gasket has elasticity), so that the connection between the lampshade 2 and the lamp holder 11 is more firm. After locking, at this time, the rotating ring 2142 is loosened, and under the cooperation of the reset spring, the rotating ring 2142 will reset along the guide plate 2143, so that the limiting block 2145 will be re-engaged in the limiting groove 2144, and then the rotating ring 2142 can be limited, avoiding loosening of the illuminating lamp in the later use.

[0056] It is worth noting that when the locking wedge block 2147 is completely inserted into the locking hole 21113, the action of the slope will make the locking rod 21112 produce upward displacement, which will produce a continuous and relatively large tightening force, tightly pressing the lampshade 2 and the lamp holder 11 together. This stable tightening force can ensure that the sealing gasket is always in a compressed state, maintaining good sealing performance, even in the case of vibration, external impact and other situations of the illuminating lamp, it can also ensure that the connection between the lampshade 2 and the lamp holder 11 will not loosen, so as to ensure the effectiveness of the sealing.

[0057] The clamping assembly 21 adopted in the present application has the following advantages:

[0058] Advantage one: during the insertion process, the "taper surface" formed between the movable block 21124 and the movable rod 2112 cooperates with the tapered hole 143 in the insertion hole 213, which can guide the insertion rod 211 to be inserted into the insertion hole 213, and can play a good guiding role, so that the insertion rod 211 can be more accurately aligned with the center of the insertion hole 213, and it is easier to insert, reducing the deviation and misplacement during insertion.

[0059] Advantage two: when the movable block 21124 contacts the tapered surface of the insertion hole 213, a force is generated to move the center towards the center, which promotes the automatic adjustment of the position of the insertion rod 211, so that the central axis of the insertion rod 211 coincides with the central axis of the insertion hole 213, ensuring the coaxiality of the two when connected. Since the central axis of each insertion rod 211 coincides with the central axis of the corresponding insertion hole 213, the coaxial installation between the lampshade 2 and the lamp holder 11 can be achieved, avoiding misplacement between the lampshade 2 and the lamp holder 11, which causes the light to be unable to scatter or gather uniformly according to the designed angle and direction, affecting the lighting effect.

[0060] Advantage three: the cooperation between the locking wedge 2147 and the inclined surface in the locking hole 21113 can provide a stable and relatively large locking force (the greater the degree of insertion of the locking wedge 2147 into the locking hole 21113 driven by the arc-shaped block 2146 cooperating with the convex block 2148, the greater the locking force between them), and the action of the inclined surface can realize the upward displacement of the locking rod 21112, the fixed rod 2111 and the lampshade 2, which in turn will drive the lampshade 2 to produce a short distance displacement (the sealing gasket has elasticity), this process will produce a continuous, relatively large tightening force, which can ensure that the sealing gasket is always in a compressed state, maintaining good sealing performance.

[0061] Advantage four: the rotating ring 2142 drives the locking wedge 2147 to be simultaneously engaged in the locking hole 21113, and the locking holes 21113 are uniformly distributed at the connection part of the lampshade 2 and the lamp holder 11, which can firmly fix the lampshade 2 on the lamp holder 11 when engaged, avoiding the position of the lampshade 2 from being shifted or deformed due to non-standard operation, thereby affecting the propagation and scattering effect of light, causing uneven light distribution and reducing lighting quality.

[0062] Lighting lamp spotlight and scatter adjustment:

[0063] After the assembly of the lighting lamp is completed, the user can realize the rotation of the threaded rod 133 in each guide groove 131 by controlling the drive unit in the shell 1. Since the sliding block 132 is threadedly connected with the threaded rod 133, the distance between the lamp plate 12 and the lampshade 2 can be adjusted as the threaded rod 133 rotates. When the distance between the lamp plate 12 and the lampshade 2 is shortened, the incident angle of the light emitted from the lamp plate 12 is relatively large when reaching the lampshade 2, and the light is reflected or refracted at a small angle on the surface of the lampshade 2, so that the light is more concentrated in one direction, thereby realizing the spotlight effect. When the distance between the lamp plate 12 and the lampshade 2 is increased, the incident angle of the light on the surface of the lampshade 2 is relatively small, and the direction of the reflected or refracted light is more dispersed, thereby realizing the diffused light effect.

[0064] When the lamp plate 12 is adjusted in position in the lamp holder 11, the electromagnetic block 141 on the piston tube 14 will instantaneously generate a pushing force on the piston head 142, so that the piston head 142 moves in the piston tube 14, and the air in the piston cylinder is compressed and delivered to the air guide pipe 22 through the conical hole 143. Under the cooperation of the arc-shaped pipe 23 and the air outlet pipe 24, the airflow can pass through the surface of the lampshade 2, so that the dust on the surface of the lampshade 2 is cleaned. After compression, the electromagnetic block 141 stops working, and the piston head 142 returns to the initial position under the cooperation of the round spring. Thus, the surface of the lampshade 2 can be cleaned every time the user switches the spotlight or the diffused light of the lighting lamp, so as to avoid the dust adhering to the surface of the lampshade 2 and affecting the use clarity of the lighting lamp.

[0065] It is worth noting that when the lampshade 2 and the lamp holder 11 are assembled, the air guide pipe 22 is inserted into the conical hole 143, so as to realize the mutual communication between the air guide pipe 22 and the piston cylinder. Since the end of the air guide pipe 22 is provided with a conical surface (the conical surface is provided with a sealing ring) which is fitted with the conical hole 143, the air-tightness of the connection between the two can be realized. Moreover, the air outlet part of the air outlet pipe 24 is provided with a tapered section. When the air flows through the tapered section of the air outlet pipe 24, the cross-sectional area gradually decreases, and under the condition that the flow rate is constant, the airflow velocity will increase accordingly, so as to better clean the dust on the surface of the lampshade 2. Moreover, a one-way valve can be installed in the air outlet pipe 24 to prevent dust and other impurities from entering the air outlet pipe 24 and affecting the normal use of the air outlet pipe 24.

[0066] The present application has the following advantages by adopting the adjusting piece 13, the piston cylinder and the air guide pipe 22:

[0067] Advantage one, during the adjustment process, each sliding block 132 is independently driven by the threaded rod 133, which can make the lamp panel 12 uniformly stressed during movement, ensure that the lamp panel 12 remains horizontal and balanced during movement, and reduce the inclination of the lamp panel 12 caused by uneven stress, which prevents the light from being used at the preset angle and affects the lighting effect.

[0068] Advantage two, the piston head 142 is driven by the electromagnetic block 141 to move in the piston pipe 14, and the air guide pipe 22 cooperates with the arc-shaped pipe 23 to deliver the airflow to the air outlet pipe 24, which can blow the airflow to the surface of the lampshade 2, so that the dust on the surface of the lampshade 2 can be cleaned in time during each position adjustment of the lamp panel 12, ensuring the clarity of the use of the lighting lamp.

[0069] Advantage three, the air outlet pipe 24 is provided with a tapered section at the air outlet position, which can gradually reduce the cross-sectional area of the gas flow, thereby significantly improving the speed of the exhaust gas flow. High-speed airflow has stronger impact force, which can effectively blow away the dust on the surface of the lampshade 2, and even the dust that is tightly attached can also be easily blown off, improving the efficiency of dust cleaning on the surface of the lampshade 2.
