Description

[0002] Existing street lamps are widely used in urban lighting to provide sufficient lighting for the city. With the development of the city, street lamps have changed from simply meeting the lighting needs to "better" meeting the lighting needs. For example, they hope that the lighting light is softer and more uniform, and the lighting light is not blocked by urban green plants or facilities such as leaves and road signs. Even in different time periods, due to the different density of vehicles and pedestrians, different lighting effects are hoped to meet the lighting needs. In addition, energy saving is also required while meeting the lighting needs. Therefore, the existing street lamps are expected to have more intelligence and more reasonable lighting structures. However, in fact, the existing street lamps often have lighting lamp heads at the top of the higher lamp poles. The starting point of the light of these lighting lamp heads is higher. In the process of irradiating the ground, there will be a problem of being blocked by leaves or other facilities such as road signs. If other street lamps cannot irradiate this position, a larger shadow will be formed on the ground, resulting in a poor lighting effect. In addition, after some lighting lamp heads have been used for a period of time, due to the influence of floating dust, there will be floating dust on the surface of the light-transmitting mirror, resulting in a poor lighting effect.

Then, the second arc lamp head rotates counterclockwise, as shown in FIG. Figure 3 As shown, at this time, the first cleaning plate can abut against the lower surface of the second arc-shaped light-transmitting plate to clean the second arc-shaped light-transmitting plate. Then the second arc-shaped lamp head continues to rotate counterclockwise, so as to rotate to Figure 4-5 The state shown in the figure, so that the cleaning fan can blow air to clean the second cleaning plate in this position. Then the second arc lamp head continues to rotate counterclockwise and can be rotated to Figure 6 The state shown is in the concentrated light filling state, and the upper surfaces of the first and second cleaning plates are shielded and thus not easily contaminated. Then the second arc lamp head continues to rotate counterclockwise, so that the first and second cleaning plates are out of contact, and then the second arc lamp head rotates clockwise to Figure 7 , 8 In the state shown, the cleaning fan can blow the first cleaning plate to clean the top of the first cleaning plate. After completion, the second arc lamp head can continue to rotate counterclockwise until Fig. 9 The state shown in FIG. 1 is shown in FIG. 1 , at which time the second cleaning plate can be used to clean the first arc-shaped light-transmitting plate. Then the second arc lamp holder continues to rotate counterclockwise, so that Fig.10 As shown, first, the second cleaning plate is abutted by the first arc-shaped abutting rod, and then continues to rotate counterclockwise, as shown in FIG. Fig.11 As shown, the first cleaning plate is abutted by the second arc-shaped abutting rod, and then continues to rotate against the trend to restore to Figure 1 The scattered fill light state shown. The above description of the process of rotating one circle means that the fill light unit can be in different states by rotating the second arc lamp head. The first purge state and the second purge state are not required for every rotation, and these can be performed selectively. For example, the scattered fill light state and the concentrated fill light state will switch once every night, but the first cleaning state and the second cleaning state may be performed once a week, and the first purge state and the second purge state may be performed once every two weeks, which can be set as needed.
