Further, the number of the light reflecting devices is two, and the light emitting directions of the light emitting parts 210 located in the two light reflecting devices are opposite.

In a specific embodiment, the present application discloses a light reflecting device for an LED lamp 200, which has a strip-shaped configuration and mainly comprises an accommodating member 120 for accommodating and positioning a light emitting portion 210 and a supporting member 110 having a reflecting portion 111, wherein the reflecting surface of the reflecting portion 111 may be added with microstructures such as squama, fillet, or frosted surface as required. The light reflecting device can effectively intercept light to avoid direct glare, and meanwhile, light energy can be reasonably distributed, so that the illuminance of a working face is more uniform.

Further, the light reflecting surface of the reflecting portion 111 is a free-form surface, and the free-form surface is adjusted during design, so that different light spot effects and different illuminance distributions are obtained.

Further, the light emitting part 210 includes an electric control board 211 and a lamp bead 212, the electric control board 211 is fixed on the side surface of the accommodating part 120, the lamp bead 212 is welded on the electric control board 211, and the lamp bead 212 is an LED lamp.

Furthermore, the reflecting surface of the reflecting part 111 is a free-form surface, and can reflect light in the opposite direction, so that light energy can be redistributed while glare is controlled, and the requirement of illuminance distribution is met.

Further, the accommodating part 120 and the supporting part 110 can form a reflection cavity 130, a light-transmitting plate is arranged at the light outlet 131 of the reflection cavity 130, the light-transmitting plate plays a role in light transmission, light mixing and protection, and microstructures such as scales, fillets and frosting can be added on the surface of the light-transmitting plate.

Specifically, the lamp beads 212 are welded on the electric control board 211, the lamp beads 212 can be lighted after being electrified, light rays are emitted from the lamp beads 212 and then irradiate on the reflecting surface of the reflecting part 111, and the reflecting surface is a free-form surface. Specifically, fig. 4 establishes a rectangular plane coordinate system with the center of the lamp bead 212, and the light emitted by the lamp bead 212 propagates in the first quadrant and the fourth quadrant before reaching the light-reflecting surface, and the energies of the two quadrants are equal. After being reflected by the reflecting surface, the light energy is transmitted in a third quadrant and a fourth quadrant, the energy percentage of the third quadrant is more than 70%, the corresponding light energy of the third quadrant is reflected to the main working area of the working surface, the light energy of the fourth quadrant is irradiated outside the main working area, the partial illumination plays a role of linking, and visual fatigue caused by overlarge difference of the edge illumination of the working area is avoided.

In addition, the reflecting surface can control the angle of the reflected light, so that the light is controlled below the viewpoint of normal human eyes, and the direct glare of the lamp 200 is avoided.

Specifically, when the light irradiates the reflecting surface and is reflected, the energy redistribution can be synchronously completed, and because the A end of the working surface is far away from the reflecting surface, the illumination close to the B end can be achieved by larger light intensity. The energy of the light is redistributed when the light is reflected by the reflecting surface, and the free curved surface of the reflecting surface is designed to adjust the energy ratio projected into the working area according to any proportion so as to meet the requirement of uniform distribution of illumination. Fig. 6 shows a redistributed light distribution curve case, where the a' curve corresponds to the energy distribution on the cross section of fig. 4, and the large light intensity is projected to about 50 degrees to make the illumination of the working face at the a end close to the B end.

Furthermore, the reflecting surface can be added with microstructures such as ridges or scaleforms to meet the light mixing requirement (as shown in fig. 2 and 3), and indirect glare caused by specular reflection when human eyes are not directly looking at the reflecting surface can be avoided.

Fig. 5 is another application expansion, fig. 4 shows that the light reflecting device irradiates light towards the back, only a small amount of light is emitted towards the front direction, and due to the strong directivity of the light, the requirement for placing the table lamp is met during application: if the desk lamp is placed on the left side of the working face, the desk lamp can normally irradiate the working area, and when the desk lamp is placed on the right side, the desk lamp cannot irradiate the working area. The expansion of fig. 5 can make up for this defect, and two reflectors shine in opposite directions, can turn on one side lamp pearl 212 selectively according to the position of putting in order to illuminate the work area, and the both sides are opened simultaneously and also can satisfy two people sitting in opposite directions and operate simultaneously.

FIG. 7 shows the distribution of the illumination of the working surface of a conventional desk lamp, with the highest central illumination and a rapid radial decay; fig. 8 shows the illuminance distribution of the desk lamp on the working surface by using the reflecting device, and the illuminance is more uniform and slowly attenuated along the radial direction, so that the high illuminance uniformity in the working area is ensured.

Light-transmitting board can be increased at light outlet 131 of the light-reflecting device to protect internal components such as reflecting part 111, electric control board 211 and lamp bead 212, and microstructures such as scaly nails, fillets and frosted sand can be added on the surface of the light-transmitting board to mix light so that the light color distribution irradiated on the working surface is more uniform.
