[0002] With the development of LED, the traditional tungsten filament has been replaced by a wick in the bulb. The wick is no longer limited to a point or line light source, but can be made into a graphic light source of different shapes and fonts to improve the aesthetics of the bulb. However, the opening of the bulb needs to be connected to the lamp holder, so the size of the opening is small, and it is difficult to insert a large graphic wick. In the prior art, the wick is split and then the two wicks are connected by a spring. When the wicks are installed in the bulb, the spring is bent to overlap the two wicks to achieve the purpose of folding, which is convenient for inserting into the bulb from the opening. However, only one of the two wicks is fixed to the lamp holder, and the other is only fixed by the spring. This causes the wick that is not fixed to the lamp holder to shake easily, so that the irradiated light and shadow shake together, which is easy to damage the eyes. In addition, the spring is prone to metal fatigue under long-term shaking, resulting in breakage, short service life, poor reliability and stability, so it is necessary to improve it.

[0023] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

[0024] A high-intensity light bulb, such as Figures 1 to 3 As shown, it includes a lamp housing 1 with an opening, a lamp holder 2 fixedly mounted on the opening of the lamp housing 1, a wick 3 is arranged on the upper part of the lamp holder 2, the wick 3 includes a fixing rod 31, a flexible frame 32, a filament 33 and at least one torsion spring, the fixing rod 31 is fixedly mounted on the lamp holder 2 and inserted into the lamp housing 1, the flexible frame 32 is fixedly mounted on the fixing rod 31, the filament 33 is arranged on one side of the flexible frame 32, the filament 33 is enclosed along the outline of the flexible frame 32 to form a graphic luminous body, the torsion spring includes a spiral spring body 34, both ends of the spiral spring body 34 respectively extend an extension rod outward, the two extension rods are respectively located on the left and right sides of the spiral spring body 34, the spiral spring body 34 is sleeved on the fixing rod 31, and the outer ends of the two extension rods are respectively fixedly connected to the flexible frame 32.

[0025] The conventional light bulb with built-in pattern filament has the filament fixed by two separate support frames, and the two separate support frames are only connected by a torsion spring. Since the torsion spring itself has elasticity, the torsion spring is easy to deform and shake during use, and the support frame shakes relatively, causing the irradiated light and shadow to shake together, causing glare and damage to the eyes. In addition, the structural strength is poor, and it is easy to produce metal fatigue and break. The utility model fixes the flexible frame 32 by the fixing rod 31, so that the filament 33 is conveniently tied and fixed on the flexible frame 32 to form a pattern luminous body, thereby increasing the aesthetics; the two extension rods of the torsion spring are respectively fixedly connected to the two sides of the flexible frame 32, and the two extension rods of the torsion spring are fixedly connected to the two sides of the flexible frame 32. When the wick 3 is inserted into the lamp housing 1, the torsion spring is compressed to deform the flexible frame 32, thereby folding the flexible frame 32 for insertion into the lamp housing 1. After insertion into the lamp housing 1, the torsion spring elastically returns to its original position to automatically unfold the flexible frame 32. The torsion spring is sleeved on the fixed rod 31, and the fixed rod 31 limits the torsion spring to prevent the torsion spring from shaking due to vibration during use, thereby increasing the supporting force of the flexible frame 32, preventing the torsion spring from metal fatigue, and extending the service life of the torsion spring. The flexible frame 32 is an integral structure, is not prone to shaking, has high structural strength, and is highly stable, thereby preventing the irradiated light and shadow from shaking due to shaking of the filament, and providing better eye protection.

[0026] Specifically, a fixing bar 321 extends downward from the lower part of the flexible frame 32, and one side of the fixing bar 321 is fixedly connected to the side wall of the fixing rod 31 by welding. The fixing bar 321 increases the connection area with the fixing rod 31, improves the structural strength, and the welding adopts a butt welding process, which is convenient for processing and production.

[0027] Specifically, at least one connecting strip 322 is extended inward from the left and right sides of the flexible frame 32, and the side walls of the two extension rods are fixedly connected to one side of the two connecting strips 322 by welding. The connecting strips 322 increase the connection area between the flexible frame 32 and the extension rods, further improving the structural strength.

[0028] Specifically, the extension rod includes an inclined section 351 and a horizontal section 352. The inner end of the inclined section 351 is integrally formed with the end of the spiral spring body 34, the outer end of the inclined section 351 is integrally formed with the inner end of the horizontal section 352, the outer end of the horizontal section 352 extends toward the flexible frame 32, and the connecting strip 322 is fixedly connected to the horizontal section 352 by welding. Since the inclined sections 351 extending from both ends of the spiral spring body 34 have a certain inclination angle, as the length of the extension rod increases, the contact points between the two extension rods and the two connecting strips 322 have a large height difference, which makes the force on the flexible frame 32 uneven. Therefore, by connecting the horizontal section 352 with the connecting strip 322, the height difference between the two connecting strips 322 is reduced, the force on the flexible frame 32 is more uniform, and the deformation of the flexible frame 32 is prevented. In addition, the width of the connecting strip 322 can be reduced, the aesthetics is improved, the material usage is reduced, and the cost is reduced.

[0029] Specifically, the two connecting bars 322 are staggered in the vertical direction, and the two extension rods are located on the same side of the spiral spring body 34. The extension rods are located on the same side of the spiral spring body 34 to prevent the torsion spring from being excessively skewed, and further prevent the flexible frame 32 from being deformed.

[0030] Specifically, the front side of the fixing strip 321 is fixedly connected to the rear side of the fixing rod 31 by welding, the two extension rods are respectively located at the front side of the spiral spring body 34, the front side of the two extension rods are respectively fixedly connected to the rear side of the two connecting strips 322 by welding, and the filament 33 is fastened to the front side of the flexible frame 32 by a binding piece. The extension rod and the fixing rod 31 are hidden to a certain extent at the rear side of the flexible frame 32, so that there is no protrusion on the front side of the flexible frame 32, which is convenient for binding and fixing the filament 33.

[0031] Specifically, the light bulb is provided with two filaments 33, and the two filaments 33 are respectively fastened to the front side and the rear side of the flexible frame 32 by binding members. By providing two filaments 33, the light bulb is illuminated on both sides, further improving the aesthetics.

[0032] Specifically, the binding member is a plurality of iron wires, and each iron wire is arranged at intervals. The filament 33 and the flexible frame 32 are bound by the plurality of iron wires at intervals, which has a simple process, high production efficiency and low cost.

[0033] Specifically, the lamp holder 2 is provided with two connecting wires 36, one end of the filament 33 is electrically connected to the fixing rod 31 or the flexible frame 32, the other end of the filament 33 is electrically connected to the first connecting wire 36, and the second connecting wire 36 is electrically connected to the fixing rod 31 or the flexible frame 32. The positive and negative electrodes of the power supply are respectively connected through the two connecting wires 36, one connecting wire 32 is directly electrically connected to the filament 33, and the other connecting wire 32 is electrically connected to the filament 33 through the fixing rod 31 or the flexible frame 32, thereby shortening the length of the connecting wires 32, reducing costs, and improving aesthetics.

[0034] Specifically, the fixing rod 31 is sleeved with a plurality of torsion springs, each of which is arranged at intervals in the vertical direction, and a connecting strip 322 is arranged on both sides of each corresponding torsion spring, and each connecting strip 322 is respectively fixedly connected to the extension rod of the corresponding torsion spring by welding. By arranging a plurality of torsion springs to support the flexible frame 32, the supporting force of the flexible frame 32 is further improved, the structural strength is improved, and the flexible frame 32 is subjected to a more uniform force, and is not easily deformed after being unfolded.

[0035] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
