Problems solved by technology

[0003] because figure 1 The middle part of the LED lamp body provides three contacts (one anode terminal, two cathode terminals or two anode terminals, one cathode terminal), so the installer needs to lay at least three wires in advance when installing the LED lamp, which increases the Wiring workload and cost before LED lamp installation

Embodiment Construction

[0031] Please refer to figure 2 , is a schematic structural view of an embodiment of the LED lamp provided by the present invention. The LED lamp mainly includes: an LED lamp body 1 and a driving module 2 .

[0032] Wherein, the LED lamp body includes: a first LED lamp string 11 and a second LED lamp string 12, and the first LED lamp string 11 and the second LED lamp string 12 are connected in antiparallel and share the first input terminal In1 and the second input terminal In2 . As for the entire LED lamp body 1, it only provides two external ports, namely In1 and In2, so the installer only needs to arrange two wires when wiring, compared with the traditional LED lamp with three contacts and three contacts. The wiring structure is more time-saving, labor-saving and cost-saving. Specifically, the light colors of the first LED light string 11 and the second LED light string 12 are different, and the power may be the same or different. In some applications, the first LED li...

Abstract

The invention provides a method for adjusting the brightness and the color temperature of an LED (light-emitting diode) lamp and the LED lamp. The LED lamp comprises a driving module and an LED lamp body, wherein the LED lamp body comprises a first LED lamp string and a second LED lamp string of which the light colors are different; after being reversely connected in parallel, the first LED lamp string and the second LED lamp string share a first input end and a second input end; and the driving module is respectively connected with the first LED lamp string and the second LED lamp string to form a driving loop and sends energy pulse signals used for controlling the energy and the light color proportion of the first LED lamp string and the second LED lamp string during the same period. The invention provides a new way for adjusting the brightness and the color temperature of the LED lamp. The brightness and the color temperature of the LED lamp are adjusted only by laying two wires in the way, so that the wiring difficulty is simplified and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a method for adjusting the brightness and color temperature of an LED lamp and the LED lamp. Background technique [0002] At present, LED lamps that can achieve adjustable brightness and color temperature generally include: a driving part and an LED lamp body part, and the common structure of the LED lamp body part is as follows: figure 1 As shown, the LED lamp body part is composed of two LED lamp strings (each LED lamp string is composed of a plurality of LED beads or LED wicks in series in the same direction) connected in parallel in the same direction. Two LED light strings share one anode terminal (+) and each occupy a cathode terminal (-), or two LED light strings share one cathode terminal and each occupy an anode terminal (-). The driving part is respectively connected with the anode terminal and each cathode terminal to form a driving circuit, and the driving part...
