TECHNICAL FIELD

The present disclosure relates to the technical field of lamps, in particular to a wrap-around flared lamp.

BACKGROUND ART

With the popularity of electricity, lamps have been used in thousands of households. People are no longer limited to using lamps for ordinary lighting, but also more inclined to use lamps to create different atmospheres. For example, people use lamps in family gatherings, parties and other outdoor entertainment venues to heighten the atmosphere of parties, spice up the parties, enhance the artistic effect, etc.

For better decoration and lighting effects, S14 large-size lamps (the diameter of each of which is about 45 mm) are usually used for decoration in meeting places. There is a lamp formed by connecting an E12 lamp base (the diameter of which is about 12 mm) to an S14 shell. According to this kind of lamp, the manufacturing cost of the lamp is reduced by reducing, the size of the lamp. Although the production cost of this kind of lamp can be reduced, an opening part of the shell needs to be reduced to a size of E12 that can adapt to a threaded part of the lamp base, so that the size of the opening part of the shell is greatly different from the overall size of the shell. As a result, when blow molding equipment blow-molds the S14 shell, the overall thickness of the S14 shell is not uniform. A part, closer to the opening part, of the shell is thicker, and a part, away from the opening part, of the shell is too thin. Furthermore, since the opening part of the shell has a small size, it is extremely difficult to control the wall thickness of the shell, and the yield is low. In order to solve the above-mentioned problems, the inventors have made new inventions.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure is described in detail below in combination ofFIGS.1-7.

The present disclosure discloses a wrap-around flared clamp, including a lamp base1and a shell2connected to the lamp base1, wherein the lamp base1is provided with an extending part11which is wrapped around and fixedly connected to an opening part of the shell2; the wrap-around flared clamp further includes a stem structure3which is electrically connected to the lamp base1and extends into the shell2; the stem structure3includes a first metal wire31, a first luminophor32and a second metal wire33which are electrically connected in sequence; and the first metal wire31and the second metal wire33are electrically connected to the lamp base1respectively. The lamp base1of the present disclosure can adopt the integrally formed extending part11above a threaded part. The extending part11is wrapped around the opening part of the shell2; the opening part of the shell2is abutted against the inside of the extending part11; the opening part of the shell2no longer needs to extend into the threaded part of the lamp base1, so that the opening part of the shell2does not need to be matched with the threaded part, and the threaded part only needs to be connected to the lamp base. The opening part of the shell2can be correspondingly made in a large size. An E12 lamp base can be connected to an E26 shell. When a blow molding machine is used to blow-mold the shell2, the overall thickness of the shell2is more uniform, and a wall thickness is easier to control. The yield of the lamp is increased. The improved lamp has a simple structure; the production cost of a large-size lamp can be reduced; and the problems that the shell2has a non-uniform thickness and low yield and is fragile can be well solved.

In order to further save the manufacturing cost, the extending part11and the lamp base1are both made of conductive metal materials and are integrally formed; and an insulation layer12is coated or sleeved outside the extending part11. The integrated forming process simplifies the lamp manufacturing flow and shortens the manufacturing time. Since the extending part11is provided with the insulation layer12, when the lamp is externally connected to a lamp holder, the insulation layer12is located between the lamp base1and the lamp holder to achieve a sealing effect. It is difficult for water to enter the lamp holder. In addition, the extending part11lengthens the lamp base1and is made of a metal material, so that when the lamp is externally connected to the lamp holder, the extending part11may be possibly partially exposed from the lamp holder. Due to the conductive effect of the metal material, the extending part11is live. In order to improve the safety, the extending part11is sleeved or coated with one insulation layer12, which can improve the safety of the lamp.

As shown inFIG.2, in order to further improve the implementation solution, an inclined part13is further arranged at a joint of the extending part11and the lamp base1. In the embodiment where the extending part11includes the inclined part13, the extending part can be further away from the lamp base1, thus achieving an objective of further enlarging the opening part of the shell2. A better technical effect is achieved; the forming yield is higher; and the wall thickness of the shell is easier to control. In another aspect, the lamp base1with the inclined part13makes the lamp more attractive. Specifically, during production and manufacturing of the lamp, the inclined part13increases a longitudinal length of the extending part11; a joint of the opening part of the shell2and the extending part11can be correspondingly shortened; the extending part11can also be correspondingly shortened; and the manufacturing cost is reduced. In addition, due to the inclined part13, during manufacturing of the extending part11, it is easier to increase a transverse width dimension of the extending part11, and it is convenient to connect the lamp base1to a larger-size lamp.

As a preference, the extending part11is provided with an outer edge14at a rim of an outer end. When the lamp base1is connected to the shell2, the outer edge14is abutted against the shell2, which has a certain sealing and waterproofing effect.

In this technical solution, there are various connection manners between the extending part11and the opening part of the shell2, such as clamping connection, adhesion or threaded connection. For the threaded connection, threads are formed at, both an inner wall of the extending part11and an outer side of the opening part of the shell2, and the extending part and the shell are in threaded connection to assemble the shell2to the lamp base1.

When the shell2and the extending part11are connected in a clamping connection manner, as shown inFIG.4, according to one implementation, an annular clamping block21is arranged on the outer side of the opening part of the shell2; and a clamping slot15matched with the annular clamping block21is arranged inside the extending part11. During assembling, the annular clamping block21of the shell2is aligned with the clamping slot15for clamping, so that the structure is simple, and the assembling is fast and convenient.

When the shell2and the extending part11are connected in a clamping connection, manner, as shown inFIG.5, as a preference, a tubular adhesive part22is arranged at the opening part of the shell2, and an outer side of the adhesive part22is adhered and fixed to an inner side of the extending part11through an adhesive. During assembling, a circle of adhesive is applied to the inner wall of the extending part11, and the adhesive part11of the shell2is slowly pushed into the extending part11for adhesion and fixing. The adhesive may be an ordinary adhesive, such as instant adhesive, or may be an adhesive with a waterproofing effect to further prevent water from entering the shell2.

As another embodiment, the stem structure3includes a plastic sealing seat34. The plastic sealing seat34fixes and supports the stem structure3. On the basis of this, the plastic sealing seat34is in hermetical tight fit with the inner side of the opening part of the shell2to further achieve a sealing and waterproofing effect. The plastic sealing seat34made of a plastic material has certain elasticity, so that the plastic sealing seat34is in tighter fit with the inner side of the opening part of the shell2, so as to achieve the sealing and waterproofing effect.

As one embodiment, the plastic sealing seat34includes a cylindrical part341used for waterproof sealing; an upper part of the cylindrical part341is connected with a supporting part342; and a lower part of the cylindrical part341is provided with a flange343. The cylindrical part341and an opening part of the plastic sealing seat34are sealed and waterproofed, and the flange343is used for covering the opening part of the plastic sealing seat34to improve the airtightness. The supporting part342has functions of supporting and positioning the first metal wire31and the second metal wire33.

In this technical solution, when a resistor needs to be mounted independently, the plastic sealing seat34is provided with at least two sealing holes344. The first metal wire31and the second metal wire33pass through the plastic sealing seat34through the sealing holes344and are connected to a wire of the lamp base1to form a complete circuit. At the same time, a bottom of each sealing hole344is sealed, so that it is hard for water to enter the shell2. In another aspect, the sealing holes344are also used for mounting a resistor4. The resistor4is generally mounted on the first metal wire31or the second metal wire33to protect the first luminophor32and prolong the life of the lamp. The resistor4is mounted in the sealing holes344to position the resistor4.

As another embodiment, when the resistor4does not need to be mounted independently, the first luminophor32is an LED lamp strip which is integrated and packaged with the resistor4. In this solution, the resistor4is directly integrated and packaged in the luminophor. The resistor4can also achieve effects of protecting the LED lamp strip and the like. At the same time, the resistor4is directly fixed, so that no other parts need to be disposed on the lamp to fix the resistor4. Therefore, the structure is simpler, and the production procedures are optimized.

As shown inFIG.6, the stem structure3of the present disclosure can also be an embodiment with two lamp strips. The stem structure3also includes a second luminophor345and a supporting column346. A bottom of the supporting column346is connected to the plastic sealing seat34, and a top is provided with a third metal wire347. Two ends of the first luminophor32are respectively connected to the first metal wire31and the third metal wire347. Two ends of the second luminophor345are respectively connected to the second metal wire33and the third metal wire347. Since the stem is provided with two luminophors, the lamp has a better lighting effect. Me symmetric luminophors are more beautiful. Of course, luminophors can be continuously added to the stem structure3according to an actual need.

Those of ordinary skill in the art can make changes to the specific implementations and application scopes according to the idea of the present disclosure, and the contents of this specification shall not be understood as restrictions to the present disclosure.
