Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model discloses a LED bulb, include from last lamp plate in lamp holder, lamp body, lamp shade and the lamp body that connects gradually extremely down. The lamp cap comprises a metal film, a metal ring, an insulating ring and a metal tube. The metal film is an elastic metal film and is connected to the top opening of the metal ring in a sealing mode. Because the metal film has elasticity, the metal film can be elastically abutted against the positive contact in the screw lamp holder, and poor contact between the contacts can be reduced. The bottom of the metal ring is sleeved and fixed in the insulating ring, the bottom of the insulating ring is sleeved and fixed in a pipe orifice at the top of the metal pipe, and the metal pipe is provided with external threads. The metal tube is provided with an external thread for connecting a threaded lamp holder.

The lamp shell is in an inverted funnel shape, the caliber of a funnel opening at the top of the lamp shell is smaller than that of a funnel opening at the bottom of the lamp shell, and the top of the lamp shell is connected with the bottom of the metal tube in a sleeved mode. The bottom of the metal tube is sleeved in the funnel at the top of the lamp shell. The lamp shell is a plastic lamp shell. The lamp shell is thicker and firmer than the lampshade. The lamp housing mainly functions as a support. The lampshade is a light-transmitting lampshade and is connected with the bottom end of the lamp shell in a sleeved mode. The lampshade is a transparent or semitransparent plastic lampshade. The lampshade is used for emitting light. Lamp plate fixed connection is provided with a plurality of LED lamp pearls on the lamp plate in the lamp body, and the anodal wire and the becket of lamp plate are connected, and the negative pole wire and the tubular metal resonator of lamp plate are connected. The LED lamp pearl of lamp plate is towards the lamp shade. LED lamp beads on one lamp panel are connected in series. Current enters the bulb through the lamp holder, the lamp panel in the bulb is switched on, and then the LED lamp beads on the lamp panel are electrified to emit light.

As shown in fig. 1, the metal film includes an upper metal film and a lower metal film which are connected to each other. The upper metal film is an arch metal film, and the lower metal film is a plane metal film. The upper metal film and the lower metal film are spaced. The arched upper metal film has better elasticity, and can further reduce poor contact. And the lower metal film can be used for standby and sealing, so that the service life is longer.

As shown in fig. 1, an elastic rubber block is padded between the upper metal film and the lower metal film. The elastic rubber block can increase the elasticity of the upper metal film and improve the supporting strength of the upper metal film, and further reduce poor contact between joints.

As shown in fig. 2, the lamp panel includes first lamp panel and second lamp panel, and the lamp pearl quantity on the first lamp panel is greater than the lamp pearl quantity on the second lamp panel. Be provided with 16 LED lamp pearls on the first lamp plate, be provided with four LED lamp pearls on the second lamp plate. The first lamp plate is parallelly connected with the second lamp plate. A pair of double-control button switches is connected in series on the positive lead of the first lamp panel and symmetrically arranged on two sides of the lamp shell. Owing to set up two lamp plates, can be as required to a lamp plate circular telegram or to two lamp plates circular telegrams simultaneously, and then obtain two kinds of bulb luminance for bulb luminance is adjustable. Because the more first lamp plate of lamp pearl quantity is connected with the switch, behind the outage electric current, can reduce the luminance of bulb more by a wide margin, can regard as the night-light to use, reduce dazzling. Because two button switches are symmetrically arranged and are double-control switches, when the bulb is laterally installed on a wall, at least one switch faces downwards, the long rod is convenient to extend to the bulb to operate the button switches nearby, and the bulb is more convenient to use.

As shown in fig. 2, the first lamp plate is circular, the second lamp plate is located at the center of the first lamp plate, the space is saved, and the light is more uniform and more attractive.
