Problems solved by technology

However, the LED controller can only control the LED light source to emit light of one color at a time, and the intensity of each light is constant, resulting in a relatively single change of light on the panel and poor decorative effect, which cannot be applied to places with high decorative requirements.

Embodiment 1

[0019] Embodiment one: if Figure 1 ~ Figure 4 As shown, an LED panel light includes a driving circuit 1, a control circuit 2, a frame body 3, a light guide plate 4 disposed in the frame body 3, an LED light emitting unit 6 disposed on the periphery of the light guide plate 4, and the LED light emitting unit 6 Located between the light guide plate 4 and the frame body 3, the drive circuit 1 is connected to the control circuit 2, and the frame body 3 is also provided with a diffuser plate 5 parallel to the light guide plate 4 and with a certain interval, and the LED light emitting unit 6 is composed of a plurality of LED lamps The LED light emitting unit 6 can emit red, green and blue light. The control circuit 2 includes a master control unit 21 and a plurality of slave control units 22. The master control unit 21 is connected to a plurality of slave control units 22, and a plurality of slave control units The unit 22 is connected to a plurality of LED lamp groups 61 in one-to...

Embodiment 2

[0023] Embodiment 2: The present invention is basically the same as Embodiment 1, except that the slave control unit 22 is composed of a TM1812 chip, fourteen resistors (R1-R14) and a capacitor C1. Such as Figure 5 As shown, the TM1812 chip has sixteen connecting pins. The first connecting pin of the TM1812 chip is respectively connected to the power supply through a resistor R13 and grounded through a capacitor C1. The second connecting pin of the TM1812 chip is connected to the power supply through a resistor R14. The main control unit 21 is connected, the third connecting pin of the TM1812 chip is the signal output terminal, and the fourth connecting pin to the fifteenth connecting pin of the TM1812 chip are connected with twelve resistors R1~R12 one by one. The LED lamp group is composed of twelve LED lamps D1-D12, and the twelve resistors R1-R12 are connected to the cathodes of the twelve LED lamps D1-D12 in one-to-one correspondence.

Abstract

The invention discloses an LED panel lamp which comprises a driving circuit, a control circuit, a frame body, a light guiding plate and an LED light emitting unit, wherein the light guiding plate is arranged in the frame body, and the LED light emitting unit is arranged on the periphery of the light guiding plate. The LED light emitting unit is located between the light guiding plate and the frame body. The driving circuit is connected with the control circuit. A diffusion plate parallel to the light guiding plate is further arranged in the frame body. The LED light emitting unit is composed of a plurality of LED lamp sets and can at least emit three-color light rays including red light rays, green light rays and blue light rays. The control circuit comprises a master control unit and a plurality of auxiliary control units, wherein the master control unit is connected with the auxiliary control units. The auxiliary control units are correspondingly connected with the LED lamp sets in a one-to-one mode. The LED panel lamp has the advantages that each LED lamp set is independently controlled by each auxiliary control unit, the LED lamp sets are combined to emit the dynamic and regular LED light rays, the LED light rays are diffused out through the diffusion plate after forming florid and attractive images so that the LED panel lamp can emit changed colors, the number of decorative modes of the color changes can reach more than one hundred, and therefore the decorative effect is good.

Description

technical field [0001] The invention relates to a panel light, in particular to an LED panel light. Background technique [0002] Existing panel lights, like natural light, fluorescent tubes and LED tubes, emit cool white light, are mainly used for lighting, and have a single function. In order to enhance the function of the panel light and expand its application field, a decorative panel light has appeared at present. The panel light is generally equipped with an LED light source that can emit three colors of red, green and blue, and the LED light source is controlled by the LED controller to emit alternately. Rays of different colors. However, the LED controller can only control the LED light source to emit one color of light at a time, and the intensity of each light is constant, resulting in a relatively single change in the light of the panel light, poor decorative effect, and cannot be applied to places with high decorative requirements.
