Embodiment 1

[0025] refer to figure 1 , the present invention divides 20 LED lamp beads 4 into three groups and connects them in parallel with the DC stabilized voltage power supply 1 respectively. The numbers of the three groups of LED lamp beads 4 are 3, 5 and 12 respectively. After the beads 4 are connected in parallel, fixed resistors R1 and R2 with different resistances are connected in series, wherein the resistance values ​​of R1 and R2 are 0.1-1000 ohms, and one end of the fixed resistors R1 and R2 is connected to the DC stabilized power supply 1 through the switch unit 2 .

[0026] The switch unit 2 adopts a double-control switch or a multi-control switch. When the switch unit 2 is transferred to the following circuit, a group containing three LED lamp beads 4 is connected in series with a fixed resistor R1, and a group containing five LED lamp beads 4 It is connected in series with two parallel fixed resistors R1, and a group containing twelve LED lamp beads 4 is connected in se...

Embodiment 2

[0030] refer to figure 2 , 60 LED lamp beads 4 are divided into 12 groups and connected in parallel, and the number of LED lamp beads 4 in each group is 5, and each group of LED lamp beads 4 is connected in series with resistors R1 and R2 respectively, and the rated power of each LED lamp bead 4 The actual working voltage is 0.5W, when the LED lamp bead 4 is working, the actual working voltage is 3.1V, the total working current of the LED lamp bead 4 is 7.2A, the actual working power of the LED lamp bead 4 is 22.32W, the rated power of the present invention is 30W LED The lights are capable of 200 lumens / watt.

[0031] working principle:

[0032] The LED lighting lamp of the present invention simultaneously adjusts the current of each group of 4 LED lamp beads through the resistor 3, so that the current of the 4 groups of LED lamp beads is just right, and the LED lamp beads 4 will not heat up due to excessive current, nor will the current be too small. Make the luminous flu...

Abstract

The invention discloses a long-service-life, high-energy-saving and environment-friendly LED illuminating lamp capable of preventing fever and belongs to the technical field of illumination. The long-service-life energy-saving and environment-friendly LED illuminating lamp capable of preventing fever comprises a stabilized voltage supply, a switch unit and LED lamp beads, wherein the number of theLED lamp beads is multiple, the LED lamp beads are connected in parallel in a grouped mode, each set of LED lamp beads is connected with the stabilized voltage supply in parallel, and each set of LEDlamp beads is connected with a resistor in series after being connected in parallel. The LED illuminating lamp is advantaged in that a plurality of LED lamp beads are connected in parallel in groupsand are electrically connected with the stabilized voltage supply and the switch unit, the LED illuminating lamp is simple in circuit structure, when the LED lamp beads work for illumination, heatingand fever are reduced, an LED radiator does not need to be added, a large amount of production cost is saved, moreover, lumen / watt of the LED lamp beads is improved, and the service life of the LED illuminating lamp is prolonged.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to an LED lighting lamp capable of preventing fever, long life, high energy saving and environmental protection. Background technique [0002] It has been more than 50 years since LED entered the market in 1962. When LED is working, it will generate heat and even burn the LED lamp beads. This problem is still an unsolved problem. At present, high-power LEDs still use 12 volts The high voltage of 220 volts is used for work and lighting. If the voltage is below 6 volts, high-power LEDs cannot start working and lighting, and high voltages may cause electric shock to the human body, and even cause life-threatening; when high-power LEDs work, heat sinks and The radiator is additionally installed on the high-power LED. In this way, the volume and weight of the high-power LED increase, which brings safety hazards and wastes resources. At the same time, the LED light control circuit board...
