Automatic temperature and voltage control LED lamp strip

Abstract

The invention discloses an automatic temperature and voltage control LED lamp strip. According to the automatic temperature and voltage control LED lamp strip, since installing circuits for LED lamp beads on a flexible circuit board are arranged in a staged staggered manner, heating points can be prevented from being centralized on one line, installing circuit board aging is relieved, and the service life of the device is guaranteed. Since the LED lamp beads are arranged in a light emitting unit circuit in parallel, even when one lamp bead is damaged, the light emitting unit circuit can be normally used under control of a control circuit, and the normal service life of the device is guaranteed. In addition, an integrated control module IC is arranged in the light emitting unit circuit, through control over an adjusting resistor IR and a temperature control module W, the work voltage and the heating situation of the light emitting unit circuit connected with the integrated control module IC can be automatically controlled and adjusted, the light emitting unit circuit is kept with the normal work voltage and current, accordingly, the usage safety performance of the device is guaranteed, and the service life of the device is prolonged. The automatic temperature and voltage control LED lamp strip is suitable for an LED lamp strip temperature and voltage control device.

Description

technical field [0001] The invention relates to the technical field of production and processing of LED light strips, in particular to an LED light strip with automatic temperature and pressure control. Background technique [0002] LED light strip refers to the assembly of LEDs on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is named because the product is shaped like a strip. It is gradually emerging in various decoration industries because of its environmental protection. Since the LED is driven by DC and requires a stable current to ensure its lifespan, the drive of the existing LED strips uses a rectifier bridge and chip capacitors, resulting in high costs. The homogeneous product drive scheme cannot allow production Manufacturers stand out in the fiercely competitive market; on the other hand, more than 95% of LED strips are for constant current, and each LED lamp bead is often connected in series with a chip resistor. The heat generated by the chi...

Since the LED is driven by DC and requires a stable current to ensure its lifespan, the drive of the existing LED strips uses a rectifier bridge and chip capacitors, resulting in high costs. The homogeneous product drive scheme cannot allow production Manufacturers stand out in the fiercely competitive market; on the other hand, more than 95% of LED strips are for constant current, and each LED lamp bead is often connected in series with a chip resistor. The heat generated by the chip resistor will affect the LED, causing The life is shortened; if the constant current is used, the cost is high and the manufacturer cannot bear it
