Embodiment 1

[0046] Existing lighting panel structures such as figure 1 As shown, the lighting panel includes a metal chassis 11, an insulating layer 12, and a conductive layer 13, wherein the metal chassis 11 and the on-off switch of the control device are electrically connected to the ground wire, and the live wire is connected to the conductive layer. The opening and closing of the control circuit as a whole controls the opening and closing of the light-emitting diode. Specifically, the conductive layer 13 may include a light emitting diode 131 , a wire 132 and related electronic devices 133 for controlling the light emitting device, wherein the light emitting diode 131 may also be called a light emitting source. Since the devices and wires in the conductive layer often include metal materials, the conductive layer and the metal chassis form a capacitor. The insulating layer is located between the conductive layer and the metal chassis, which is equivalent to the insulating medium in th...

Embodiment 2

[0055] Based on the panels described in the above embodiments, the present application further provides a lighting panel, wherein at least one group of parallel-connected light-emitting diodes among the at least one light-emitting diode is connected in parallel with a resistor.

[0056] Such as Figure 4 As shown in the figure, three groups of light emitting diodes connected in parallel are shown in the figure, which are respectively light emitting source group 41, light emitting source group 42 and light emitting source group 43. Each group of light emitting sources includes three light emitting diodes connected in parallel, wherein the light emitting diodes A resistor 41a is connected in parallel at both ends of the light source group 41, and two resistors are connected in parallel at both ends of the light emitting source group 42, which are respectively a resistor 42a and a resistor 42b. The three light emitting sources in the light emitting source group 43 are respectively c...

Embodiment 3

[0078] Based on the above embodiments, the present application also provides a lighting fixture, such as Figure 13 As shown, it includes: a driving power supply 131 , any lighting panel 132 described in the above embodiments, and a lampshade 133 . Wherein, the driving power supply 131 can be an isolated power supply or a non-isolated power supply, and the power supply can be integrated on the lighting panel or set separately from the lighting panel.

[0079] The isolated power supply refers to the power supply that isolates the power supply into the circuit from the mains. Specifically, a 1:1 power frequency transformer can be used for isolation. For this kind of power supply, the operator will not touch any line of the line. There is a risk of electric shock because the isolated power supply is not connected to earth. Therefore, the isolated power supply can improve safety and avoid electric shock to experimenters to a certain extent. In industrial control equipment, it is...

Abstract

The invention relates to the technical field of lighting, in particular to a lighting panel and a lighting lamp. The problem that in the prior art, after power failure, a light-emitting source is slightly light is solved. The lighting panel comprises a metal chassis, an insulation layer covering one surface of the metal chassis and a conducting layer arranged on the insulation layer; the conducting layer comprises at least one light-emitting diode, and two ends of each light-emitting diode are in parallel connection with at least one resistor. In the lighting panel, through the manner that theresistor is in parallel connection to the two ends of a light-emitting source, after current flows through a resistor, the current flows to a null line through a distributed capacitor, the current isprevented from flowing through the light-emitting source, the phenomenon that the current in a firing line flows through the light-emitting source, and the current flows to the zero line through thedistributed capacitor is avoided, it is ensured that when a device switch is off, the light-emitting source cannot emit light, and control over the light-emitting source is achieved.

Description

technical field [0001] The present application relates to the technical field of lighting, in particular to a lighting panel and a lighting fixture. Background technique [0002] In the existing lighting technology field, lighting fixtures are often composed of a substrate, a power supply module, and a light-emitting module. The above-mentioned structure often includes metal materials, for example, a metal substrate, a power supply module containing metal wires, and a Lighting modules, etc. Capacitance is often formed between metal structures or components, and this kind of capacitance distributed in various parts of the lighting substrate can be called distributed capacitance. [0003] After the lighting fixture is turned off, part of the distributed capacitance causes a voltage difference between the two ends of the light emitting source. When the lighting fixture is turned off, there is still a weak current flowing through the light emitting source, resulting in the inab...
