Description

A kind of bulb

Technical Field

The utility model relates to the field of lamps and lanterns, in particular to bulb.

Background

The LED lamp has the advantages of energy conservation, electricity saving, no pollution and the like. The existing bulb is usually provided with a lampshade outside an LED lamp bead, and because light rays emitted by the LED lamp bead are limited by a light-emitting angle, the light rays are difficult to be uniformly distributed on the whole lampshade, so that the light rays actually emitted by the bulb are not uniform. Therefore, it is necessary to provide a new bulb, which can guide the light emitted by the LED lamp bead and improve the uniformity of the actual light emission of the bulb.

It is seen that improvements and enhancements to the prior art are needed.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned deficiencies of the prior art, an object of the present invention is to provide a bulb, which aims to solve the technical problem of uneven lighting of the bulb in the prior art.

In order to achieve the purpose, the utility model adopts the following technical proposal:

a bulb comprises a lamp holder, a lampshade, a base, a light guide column and an LED lamp bead, wherein the LED lamp bead is arranged in the light guide column and is electrically connected with the lamp holder; the light guide column is coaxially arranged with the base and comprises a cylindrical section and a conical section.

Further, in the bulb, the lampshade is in a segment shape.

Further, in the bulb, an annular protrusion is arranged at the top of the base, an annular recess is arranged at the bottom of the lampshade, and the annular protrusion is inserted into the annular recess.

Further, in the bulb, the lampshade and the base are welded through ultrasonic waves.

Furthermore, in the bulb, the lamp holder is provided with an external thread.

Further, in the bulb, the taper angle of the conical section is 30-45 degrees.

Has the advantages that: the utility model provides a bulb compares prior art, and through setting up the leaded light post, the light beam that the later stage sent is mainly lighted to LED lamp pearl is shot out to the emiction and upwards to one side after the circular cone section of leaded light post, and the light that few light beams and the circular cone section reflection that LED lamp pearl sent back can be shot out and further jet out from the lamp house through the cylinder section. Because the light guide column, the lampshade and the base are coaxially arranged, and the LED lamp beads are positioned on the axis of the light guide column, light rays emitted by the LED lamp beads can be uniformly distributed in all directions of the lampshade, the light-emitting uniformity of the bulb is improved, and the light-emitting effect is improved.

Detailed Description

The utility model provides a bulb, for making the utility model discloses a purpose, technical scheme and effect are clearer, make clear and definite, and it is right that the following combination embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 4, the present invention provides a lamp bulb. The terms "top," "bottom," "upper," "lower," and the like are used herein for convenience of description based on the perspective of the drawings, and are not intended to be limiting in actual use.

The bulb comprises a lamp cap, a lampshade, a base, a light guide column and an LED lamp bead (not shown in the figure), wherein the LED lamp bead is arranged in the light guide column, the LED lamp bead is electrically connected with the lamp cap, the light guide column and the base are integrally formed, and the lampshade is connected with the base; the light guide column is coaxially arranged with the base and comprises a cylindrical section and a conical section. The bulb is of a rotary structure on the whole, the light guide column, the lampshade and the base are coaxially arranged, and the LED lamp beads are located on the axis of the light guide column. As can be observed from FIG. 3, the bottom of the base is provided with an opening 200 that communicates with the inner cavity of the light guide 4. The LED lamp beads are arranged at the top of the lamp holder, and when the lamp holder is connected with the base, the LED lamp beads are arranged in the light guide column and correspond to the bottoms of the circular sections.

Furthermore, the lampshade 1 is in a spherical segment shape, so that light rays can be emitted from all directions of the lampshade uniformly. The lampshade is spherical on the whole after being connected with the base, and the transition between the lampshade and the base is natural, namely, the bulb is a G35 type bulb and is uniform in light emission.

As shown in fig. 2, it is preferable that the base is provided at the top with an annular protrusion 21, and the lamp cover is provided at the bottom with an annular recess 11, and the annular protrusion 21 is inserted into the annular recess 11 to facilitate the coupling between the lamp cover and the base.

Preferably, the lampshade 1 and the base 2 are welded through ultrasonic waves, so that the welding is convenient, and the lampshade and the base are firmly connected.

Preferably, the lamp cap 3 is provided with an external thread 31, which facilitates screwing into the corresponding lamp cap in actual use.

Preferably, the conical section 41 has a cone angle of 30 ° to 45 °.

Preferably, the height of the conical section 41 is 6mm to 8 mm.

Preferably, not only the lampshade is light-transmitting, but also the light guide column and the base are light-transmitting, and further, the light-emitting angle of the bulb is improved.

Compared with the prior art, through the light guide column, the light splitting lines emitted in the later stage of lighting of the LED lamp beads are emitted upwards and obliquely upwards mainly through the conical section of the light guide column, and the light rays emitted by the LED lamp beads, reflected by a small part of the light rays and the conical section, can be emitted through the cylindrical section and further emitted from the lamp shade and the base. Because the light guide column, the lampshade and the base are coaxially arranged, and the LED lamp beads are positioned on the axis of the light guide column, light rays emitted by the LED lamp beads can be uniformly distributed in all directions of the lampshade, the light-emitting uniformity of the bulb is improved, the light-emitting effect is improved, and the luminous flux of the bulb is improved under the same power.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
