Description
Technical Field
The invention relates to the field of LED chips, in particular to a gradually-flickering LED chip.
Background
An LED is a semiconductor electronic component that converts electrical energy into light energy. Such electronic devices appeared as early as 1962, and only low-intensity red light was emitted in the early stage, and other versions of monochromatic light were developed later, and the light emitted so far has spread to visible light, infrared light and ultraviolet light, and the light intensity has been improved to a comparable level. The utility model can be used as an indicator light, a display panel and the like at the beginning; with the continuous progress of technology, light emitting diodes have been widely used for displays, television lighting, and illumination. The LED sometimes needs to create a flickering effect, the current common method is to enable the light-emitting chip to be turned on and off according to a certain frequency, but the LED is turned on or off when flickering, the brightness change is too large, and no transition stage exists in the middle, so that the LED is not natural enough.
Disclosure of Invention
The technical problem to be solved by the embodiments of the present invention is to provide a gradually flickering LED chip, which changes the brightness by changing the light emitting angle of the LED light emitting chip, so that the flickering effect is more natural.
In order to achieve the purpose, the invention discloses a gradually-changing-type flickering LED chip which comprises a substrate, wherein a plurality of mounting grooves are formed in the upper side of the substrate, a protrusion is formed in the middle of each groove, a rotating plate is hinged to the top end of the protrusion, the bottom surface of the LED chip is mounted on the rotating plate, a wiring end is formed in the rotating plate, the LED chip is connected to the wiring end in a guiding mode, a conducting wire extends out of the wiring end to be connected with a power supply, the rotating plate is made of a magnetic material, a first electromagnet and a second electromagnet are arranged on two sides of the protrusion respectively, and an oscillating circuit for driving the first electromagnet and the second electromagnet is arranged on the lower side of.
Preferably, the first electromagnet is directly connected to the output U0 of the oscillator circuit, and the second electromagnet is connected to the output U0 of the oscillator circuit through a not gate.
Preferably, the lead of the LED chip is connected to a power supply through the inside of the protrusion.
Compared with the prior art, the invention has the beneficial effects that:
the recess has on the base plate, the recess middle part has the arch, protruding top is rotated and is connected with the magnetism rotor plate, protruding both sides are provided with firstly, the second electro-magnet, through first, second electromagnetism ferromagnetism attracts the control rotor plate to make a round trip to rotate, the LED chip is installed on the rotor plate, because the recess is all nontransparent all around, light can only follow recess open-top and jets out, therefore, when the LED chip changes the angle along with the rotor plate rotation, the luminance of light also changes along with the angle of light-emitting of the luminous chip of LED, because the angle of light-emitting is continuous variation, the luminance of light also continuous variation, can not be like the scintillation of traditional mode neglected, the scintillation effect is more natural.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings of fig. 1-3.
As shown in fig. 1 to 3, a gradually-changing flickering LED chip comprises a substrate 1, a groove 2 is formed on the substrate 1, a protrusion 5 is formed in the middle of the groove 2, a bottom surface of a magnetic rotating plate 4 is rotatably hinged to the top end of the protrusion 5, first and second electromagnets 8, 9 are respectively disposed on two sides of the protrusion 5, an oscillating circuit 7 for driving the first and second electromagnets 8, 9 is disposed on the bottom surface of the substrate 1, the magnetic rotating plate 4 is driven to rotate in a reciprocating manner by controlling the first and second electromagnets 8, 9 to be alternately energized, the LED chip 3 is mounted on the magnetic rotating plate 4 and rotates in a reciprocating manner with the magnetic rotating plate 4, since the groove 2 is not transparent around, light can only be emitted from the top opening of the groove 2, the light output amount is continuously changed along with the angle of the LED chip 3, the brightness is also continuously changed, there is no flickering sensation which is neglected in the conventional manner, but the gradually-changing light and shade are alternated, the effect is better. The oscillating circuit is composed of a 555 time-base circuit.
Preferably, the first electromagnet 8 is directly connected to the output U0 of the oscillator circuit 7, and the second electromagnet 9 is connected to the output U0 of the oscillator circuit 7 through a not gate. According to the LED illuminating lamp, when the first electromagnet 8 is at a high level, the second electromagnet 9 is at a low level, when the first electromagnet 8 is at a low level, the second electromagnet 9 is at a high level, the first electromagnet 8 and the second electromagnet 9 are matched with each other, so that the LED illuminating chip 3 regularly and quickly changes the light emitting angle, the light flashing effect is better, and the flashing is more natural.
The lead 6 of the LED chip 3 passes through the inside of the bump 5 to be connected with a power supply. The wiring mode is clean and simple, the lead 6 can be effectively fixed, and poor contact caused by loosening of the lead 6 due to frequent shaking of the LED light-emitting chip 3 is avoided.
