Technical Field

The invention relates to the technical field of LED lamps, in particular to an LED colored lamp for decorating a building.

Background

The LED lamp can directly convert electrical energy into light energy, and in order to pursue a gorgeous lighting effect, the lamp body often emits light with different colors and variations, which is called as an LED color lamp.

Among them, the function of the LED colored lamps used in building is more biased towards the decorative effect. However, the existing LED colored lamp light changes mostly through the control of the light flicker frequency by an electronic program, and because the electronic program depends on the control of equipment such as a computer, the installation route of the lamp and the whole equipment are complex, so that the construction difficulty is high, the occupied area of the equipment is large, the electric energy consumption is high, and the repair difficulty is high when the equipment breaks down.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides an LED colored lamp for decorating a building.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a building is decorated and is used LED color lamp, includes the lamp area and installs the lamp body in the lamp area, install LED color lamp pearl in the lamp body, square chamber has been seted up to the lateral wall of lamp body, square intracavity bottom fixedly connected with arc cover, just the arc cover is made by piezoceramics material, just the both ends of arc cover are established ties in the power supply circuit of LED color lamp pearl through electric capacity, the ventilation hole has been seted up to the lateral wall of lamp body, just through the negative pressure hole intercommunication between ventilation hole and the square chamber, the circular recess of ventilation hole intercommunication is seted up to the lateral wall of lamp body, install the speed change gear of the downthehole wind speed of drop cloth ventilation in the circular.
