With the further maturity of LED technology, LEDs will make more and better developments in the field of design and development of household lighting fixtures. The design of the lamp in the room in the 21 st century takes the design of an LED lamp as the mainstream, and fully reflects the lighting development trends of energy conservation, health, artistic and humanization at the same time, so that the lamp becomes the leading factor of the lighting culture of the room. In the new century, the LED lighting lamp can illuminate the living room of each person, change the life of each person and become a great revolution of development and design of the lamp; an LED is a green light source. The LED lamp is driven by direct current without stroboflash; the LED lamp has no infrared and ultraviolet components, no radiation pollution, high color rendering and strong light emitting directivity; the dimming performance is good, and visual errors can not be generated when the color temperature is changed; the cold light source has low heat productivity and can be safely touched; these are not achievable with incandescent and fluorescent lamps. The light source can provide comfortable illumination space, well meet the physiological health requirements of people, and is a healthy light source which protects eyesight and is environment-friendly; because a single LED has low power and low brightness, the LED is not suitable for being used independently, and the practical LED lighting lamp designed by assembling a plurality of LEDs together has wide application prospect.

When the LED lamp bead is used for illumination, a large number of LEDs are usually combined in a lamp, and a layer of light equalizing plate is arranged on a light source propagation path, so that light forms a diffuse reflection phenomenon inside the light equalizing plate, and the purpose of light equalization is achieved; meanwhile, because a large number of lamp beads are arranged together, the temperature near the lamp beads is increased, so that the lamp beads are aged, and the service life of the lamp beads is influenced; the driving wheel 6 is driven to rotate through the rotation of the arranged motor 5, the driven wheel 7 is driven to rotate, the rotating shaft 4 is driven to rotate, the lamp panel 10 and the fan blades 9 are driven to rotate, and the lamp strip 11 is driven to rotate; because the lamp strip 11 rotates in the horizontal direction, the lamp beads on the lamp strip 11 are in a rapid movement state, and the light-emitting positions of the lamp beads are not fixed, so that a region with higher brightness is not formed at one position, and the light rays are diffused outwards more uniformly, thereby achieving the effect of light uniformity; meanwhile, when the rotating shaft 4 rotates, the fan blades 9 rotate, so that air at the lower part of the fan blades 9 is pumped to the upper part of the fan blades 9, a negative pressure region is formed in the lower region of the fan blades 9, and further, air at the lower part of the lamp panel 10 enters the lower region of the fan blades 9 through the backflow hole 12 along the center of the rotating shaft 4, and further, airflow circulation is formed in the LED lamp and circulates in the direction indicated by an arrow in fig. 3, so that heat emitted by the lamp beads is taken away quickly, further, heat is prevented from being collected by the lamp beads, further, the lamp beads are prevented from being aged due to overhigh temperature, and the service life of the lamp is prolonged; meanwhile, the rapid flow of the internal air also accelerates the internal temperature and transfers the internal temperature to the shell 1, so that the internal temperature of the lamp is further reduced, the lamp beads are prevented from being aged due to overhigh temperature, and the service life of the lamp is prolonged; in the static light-equalizing LED lamp, in order to avoid the situation that different positions on the lamp have different brightness, the internal lamp beads are generally arranged densely, and the lamp in the scheme realizes uniform light emission through the rotation of the lamp strip 11, so that the situation that different areas have different brightness in the lamp is avoided, and the internal lamp beads are not required to be arranged densely, so that the power consumption of the lamp in use is reduced, and the lamp has the performance of energy conservation and environmental protection while emitting light uniformly; in the rotating process of the fan blades 9, airflow is formed to flow inside the lamp, and through the arranged filter element 13 and the filter ring 14, as the filter element 13 and the filter ring 14 are both of a loose and breathable structure, when the air inside the lamp rapidly flows, part of the air inside the lamp can exchange with the outside air through loose holes in the filter element 13 and the filter ring 14, so that the inside air and the outside air can circulate, the heat inside the lamp is transferred to the outside of the lamp along with the exchange of the inside air and the outside air, the temperature inside the lamp is reduced, the lamp beads are prevented from being aged due to overhigh temperature, and the service life of the lamp is prolonged; meanwhile, the arranged filter element 13 and the filter ring 14 ensure that the air inside and outside can be exchanged, and when the outside air enters the inside, the filter element 13 and the filter ring 14 filter the dust in the air, so that the inside of the lamp is clean, the dust in the lamp is prevented from being deposited, and the brightness of the lamp is prevented from being reduced due to the dust deposited in the lamp; because the elastic sheet 18 is in a curved wave shape, the elastic sheet 18 has a certain width (i.e. the distance between the wave-shaped wave crests and wave troughs), one side of the elastic sheet 18 is clamped in the first clamping groove 16, so that the degree of freedom of the elastic sheet 18 in the direction perpendicular to the lamp panel 10 is restricted, meanwhile, because the other end of the elastic sheet 18 is positioned in the second clamping groove 17, so that the degree of freedom of the lamp strip 11 in the direction perpendicular to the lamp panel 10 is restricted, and the effect of installing the lamp strip 11 is achieved, so that the lamp strip 11 is prevented from falling off, meanwhile, because the elastic sheet 18 is a curved pile, the contact area between the elastic sheet 18 and the lamp strip 11 is smaller, and the space occupied by the elastic sheet 18 which is curved under the same width is smaller, so that a gap is left between the lamp strip 11 and the lamp strip 10, and further, when the lamp strip 11 rotates, heat generated by the lamp strip 11 is easy to, the heat dissipation effect of the lamp is further improved; meanwhile, the lamp strip 11 is rotated to dissipate heat and homogenize light when in use, so that the lamp strip 11 can be subjected to larger acting force in the use process, the lamp strip 11 is damaged, the service life of the lamp is further shortened, the lamp strip 11 is installed in the elastic piece 18 mode, when the lamp bead is subjected to centrifugal force, the elastic piece 18 can absorb the acting force of a part acting on the lamp strip 11 through the deformation of the elastic piece 18, the external force on the lamp bead is further reduced, the lamp strip 11 is prevented from being damaged due to rotation, and the service life of the lamp is further prolonged; the edge of the shell 1 (namely, the position A in figure 5) is set to be in a circular arc structure, so that the arc length of the section of the shell 1 at the corner is increased, the area of the shell 1 at the corner is increased, when the fan blades 9 rotate to drive the internal gas to flow, the time of the air staying at the corner of the shell 1 is longer, the contact area between the air flow and the corner of the shell 1 is larger, the heat in the air can be better transferred to the shell 1, the contact area between the shell 1 and the external air is increased through the heat dissipation plate 26 arranged outside the shell 1, the heat transferred to the shell 1 inside the shell 1 can be more quickly transferred to the external air, the heat dissipation effect of the lamp is further increased, the internal temperature of the lamp is prevented from being higher during operation, and the aging phenomenon of the lamp strip 11 caused by high temperature is further reduced, and then increased lamp strip 11's life, and then increased the life of lamps and lanterns.
