Description

A kind of LED lamp

technical field

The utility model relates to a lighting appliance, in particular to an LED lamp.

Background technique

With the rapid development of LED technology, LED lamps have gradually become new lighting products that replace traditional lamps.

Existing LED lamps usually consist of a lampshade and a base. Chinese patent CN2442092 discloses a disc lampshade. It is a spherical crown, and its sides are bent into a cylindrical shape. There are positioning convex rings and uniformly distributed oblique buckles on the outside of the cylinder; The hole corresponding to the oblique buckle; since the cover and the cover base have a certain degree of elasticity, fix the cover base first when installing, then hold the cover so that the oblique buckle is aligned with the buckle hole on the cover base, slightly It can be installed as soon as it is pressed firmly; when disassembling, pinch the cover with your hands and tilt it left and right with a little force to remove it. Although this lampshade can be easily installed and disassembled, the patent divides the lampshade into two parts, which increases the difficulty and cost of processing.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide an LED lamp. The lampshade is molded by injection molding or blow molding at one time, which greatly simplifies the processing difficulty and reduces the processing cost.

In order to achieve the above object, the utility model is realized through the following technical solutions:

An LED lamp, comprising a lamp base, a lampshade, a circuit board, a driver and an LED light source, the side of the lamp base is a cylindrical surface, the LED light source is mounted on a circuit board, and the circuit board is mounted on the lamp by screws On the base, at least two blocks are arranged on the inner side of the cylindrical surface. The lampshade is injection molded or blow molded at one time. The emitted light is emitted from the light-emitting part, the connecting part is provided with recessed parts equivalent to the number of the stoppers, and a blocking part is provided adjacent to the recessed parts.

As a further optimization of this solution, the circuit board is an aluminum substrate.

As a further optimization of this solution, a through hole is opened on the base of the lamp, and the driver is connected with an electrical connection line, and the electrical connection line passes through the through hole to connect with an external power supply circuit.

As a further optimization of this solution, the lamp base is made of metal material.

As a further optimization of this solution, the driver is connected to the base of the lamp through screws.

As a further optimization of this solution, the number of the stoppers is 3.

As a further optimization of this solution, a decorative layer is provided outside the decorative part.

The lamp provided by the utility model can not only save energy, but also realize assembly facilitation and reduce processing cost.
