Background

The LED lamp beads are just light emitting diodes, and the light emitting diodes are called LEDs for short.

In circuits and instruments as indicator lights or to form text or numerical displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Organic light emitting diodes OLED and inorganic light emitting diodes LED are classified by their chemical properties. The terminal voltage of the PN junction forms a certain potential barrier, when a forward bias voltage is applied, the potential barrier is lowered, and most carriers in the P region and the N region diffuse to each other. Since electron mobility is much greater than hole mobility, a large number of electrons will diffuse into the P region, constituting an injection of minority carriers into the P region. These electrons recombine with holes in the valence band and the energy obtained upon recombination is released as light energy.

a first eccentric column 42 is arranged on the end face of the first gear 36, a second eccentric column 43 is arranged on the end face of the second gear 41, one end of the first eccentric column 42 is connected with the first gear 36, the other end of the first eccentric column 42 is rotatably connected with a first arc-shaped slide block 44, one end of the second eccentric column 43 is connected with the second gear 41, the other end of the second eccentric column 43 is rotatably connected with a second arc-shaped slide block 45, a moving plate 46 is arranged in the cavity 5, an arc-shaped slide groove 47 is arranged on the moving plate 46, the first arc-shaped slide block 44 and the second arc-shaped slide block 45 can reciprocate in the arc-shaped slide groove 47, guide rods 48 are arranged at two ends of the moving plate 46 in the length direction, two ends of the guide rods 48 are respectively connected with the inner wall of the cavity 5, the guide rods 48 penetrate through the moving plate 46, and the moving plate 46 can reciprocate along the guide rods 48, brush boards 49 are respectively arranged at two ends of the moving board 46 in the width direction, bristles on the brush boards 49 are in contact with the dust filter screen 31, the arc-shaped sliding groove 47 is located between the two brush boards 49, a first elastic block 50 is arranged on the first arc-shaped sliding block 44, a second elastic block 51 is arranged on the second arc-shaped sliding block 45, and the first elastic block 50 and the second elastic block 51 are oppositely arranged.

The working principle and the beneficial technical effects of the technical scheme are as follows: when the heat productivity of the lamp bead is high, the second motor 39 is started to drive the second gear 41 to rotate, the second gear 41 and the first gear 36 are driven to rotate at the same rotating speed in opposite rotating directions through the meshing of the second gear 41 and the first gear 36, on one hand, the first gear 36 drives the third rotating shaft 34 and the fan 33 to rotate, and the air blown by the fan is blown to the lamp bead through the heat dissipation holes 32 for air cooling and heat dissipation, on the other hand, the second gear 41 and the first gear 36 rotate in opposite directions, so that the second eccentric column 43 and the first eccentric column 42 drive the second arc-shaped sliding block 45 and the first arc-shaped sliding block 44 to reciprocate in opposite directions in the arc-shaped sliding groove 47, and meanwhile, the moving plate 46 can also reciprocate up and down along the guide rod 48 to drive the brush plate 49 to clean the surface of the dust filter screen 31 to prevent the dust filter screen from being blocked, when the second arc-shaped sliding block 45 and the first arc-shaped sliding block 44 move in opposite directions, the first elastic block 50 and the second elastic block 51 collide with each other to generate instantaneous vibration, so that the brush attachment on the brush plate 49 is shaken off to keep the brush clean.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
