Embodiment 1

[0014] Such as figure 1 A method for controlling the intensity of LED light is shown, the LED lamp includes several LED lamp beads 1, and the LED lamp beads 1 form several concentric ring-shaped LED lamp bead arrays 2; the LED lamp beads 1 are all arranged in parallel, and each The LED lamp bead 1 is correspondingly equipped with an electromagnetic switch; when the LED lamp is used as the light source of the microscope, a certain ring-shaped LED lamp bead array 2 in the middle is controlled by the electromagnetic switch to be bright, and the other ring-shaped LED lamp bead arrays 2 are dark to form differential imaging; when the LED lamp When used as an indoor light source, when the LED light is controlled to be extinguished, the LED lamp beads 1 are connected in series from the inside to the outside and gradually extinguished, and the total extinguishing time is 0.5-5min.

[0015] When the LED lamp is used as an indoor light source, when the LED lamp is controlled to turn on,...

Abstract

The invention discloses an LED lamp light intensity control method. An LED lamp comprises a plurality of LED lamp beads, and the LED lamp beads form a plurality of concentric annular LED lamp bead arrays; the LED lamp beads are arranged in parallel, and each LED lamp bead is correspondingly provided with one electromagnetic switch. When the LED lamp serves as a microscope light source, a certain annular LED lamp bead array 2 in the middle is controlled to be turned on through an electromagnetic switch, and the other annular LED lamp bead arrays 2 are dark to form differential imaging. When theLED lamp serves as an indoor light source and the LED lamp is controlled to be turned off, the LED lamp beads 1 are connected in series from inside to outside and are gradually turned off, and the total turn-off time is 0.5-5 min. The LED lamp is divided into a plurality of folding blocks through rotating shafts which are arranged up and down at intervals, so that the occupied area of the LED lamp can be reduced through folding, and the LED lamp is convenient to store and transport.

Description

technical field [0001] The invention belongs to the field of electronic equipment, and in particular relates to a method for controlling the intensity of LED lights. Background technique [0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and sealed with epoxy resin around it to protect the inner core wire. role, and finally install the shell. LED lamps are often used as indoor light sources or lamps for microscopic equipment. However, as an indoor light source, it usually changes or turns black in an instant when it is turned on or off, which is easy to damage people's eyesight. When used as a microscopic light source, it usually emits light as a whole, and it is difficult to form a differential image. Contents of the invention [0003] In order to solve the above problems, the present invention provides a...
