Description

Bracket lamp with three-color light switching function

The present invention relates to a lamp, in particular to a bracket lamp with a three-color light switching function.

Existing bracket lamps can be roughly divided into three types: white light tubes, yellow light tubes and natural light tubes to meet the needs of different indoor scenes of buildings. Therefore, when carrying out construction, plumbing and electrical assembly personnel must prepare materials according to the different numbers of white light tubes, yellow light tubes and natural light tubes to facilitate on-site construction.

However, preparing bracket lights with similar appearance but different colors is not only easy to make mistakes in bringing the wrong bracket lights, but once the owner wants to change the light color, the installed bracket lights must be removed one by one to make the change, making the overall construction process more cumbersome.

In addition, in order to facilitate material preparation, the warehouse of water and electricity assembly personnel must be equipped with a large number of bracket lights of different colors, which causes great inventory pressure and makes it impossible to reduce operating costs.

Therefore, the purpose of the present invention is to provide a bracket lamp with a three-color light switching function that overcomes the shortcomings of the prior art.

Therefore, the bracket lamp with three-color light switching function of the present invention includes a lamp bracket unit, a light strip unit, and a circuit unit.

The lamp holder has an electrical slot extending in the first direction, and the lamp shade has a lamp slot extending in the first direction. The light bar unit includes a lamp board passing through the lamp slot, a first lamp assembly and a second lamp assembly. The first lamp assembly has a plurality of lamps arranged on the lamp board in the first direction and The first light-emitting elements are connected in series with each other, the second light assembly has a plurality of second light-emitting elements arranged on the light board along the first direction and connected in series with each other and arranged alternately with the first light-emitting elements, the first light-emitting elements can emit a first color light after being powered on, and the second light-emitting elements can emit a second color light after being powered on, the circuit unit includes a power drive module arranged in the electrical slot and electrically connected to the first light assembly and the second light assembly, and a switching switch set electrically connected to the power drive module, the switching switch set having a first switch electrically connected to the power drive module and the first lamp set, and a second switch electrically connected to the power drive module and the second lamp set, the switching switch set can switch between a first mode, a second mode and a third mode, in the first mode, the first switch is turned on to make the first light emitting elements emit light, and the second switch is turned off to make the first light emitting elements emit light The first switch is not conducting so that the second light-emitting elements do not emit light. In the second mode, the first switch is not conducting so that the first light-emitting elements do not emit light, and the second switch is conducting so that the second light-emitting elements emit light. In the third mode, the first switch is conducting so that the first light-emitting elements emit light, and the second switch is conducting so that the second light-emitting elements emit light. The light emitted by the first light-emitting elements and the second light-emitting elements are mixed together to form the third color light.

When the switch set 42 is switched to the third mode, the first light emitting elements 321 and the second light emitting elements 331 can be powered on to emit light, and together they mix to produce a third color light, which is then emitted to the outside through the lampshade 22.

Therefore, when the water and electricity assembly personnel are preparing materials, they do not need to prepare different bracket lights separately, but only need to prepare a sufficient number of bracket lights with three-color light switching function, which can avoid the error of bringing the wrong bracket light, and can adjust the luminous color of the bracket light in real time at the assembly site, which can greatly improve the convenience of material preparation and construction. In addition, when the water and electricity assembly personnel's warehouse is feeding materials, they do not need to prepare bracket lights of different colors, so it can greatly reduce the inventory pressure of raw materials.

In summary, by providing the first light emitting elements 321, the second light emitting elements 331, the power drive module 41 and the switch set 42, the bracket lamp with three-color light switching function can adjust three light colors as needed, improve assembly convenience and reduce inventory pressure, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
