As shown in fig. 1 and fig. 2, the reflective sheet 1 of the present embodiment includes a carrier layer 11 and a reflective film 12, wherein the carrier layer 11 is used for fixing the reflective film 12, so that the reflective film 12 can be attached to the carrier layer 11 for fixing; in this embodiment, both the front and back surfaces of the reflective film 12 have a reflective function, and the carrier layer 11 is made of a transparent material, so that both the front and back surfaces of the reflective sheet 1 have a reflective effect. The carrier layer 11 is made of flexible materials, so that the reflector 1 can be bent into a corresponding radian according to the specific structure of the lamp to be installed in the lamp. In this embodiment, the carrier layer 11 is a trapezoid structure, so that the left and right sides of the carrier layer 11 are connected to form a carrier with a taper structure, and the light source is disposed at the bottom of the carrier with a taper structure.

Meanwhile, the reflector 1 needs to be bent and arranged inside the lamp, so that the thickness of the carrier layer 11 needs to be controlled to be 0.1-0.2 mm, and the thickness of the reflective film 12 needs to be controlled to be 0.03-0.08 mm, so that the reflector 1 integrally keeps certain flexibility, and the reflector 1 is convenient to mount and fix. In this embodiment, the carrier layer 11 is set to 0.15mm, and the reflective film 12 is set to 0.05 mm.

The reflector 1 of the present embodiment includes at least two reflective films 12, and the reflective films 12 are attached to the carrier layer 11; each reflection film 12 is provided with a light hole 13 for transmitting light; meanwhile, a certain gap is formed between two adjacent reflecting films 12, so that a light-transmitting strip 14 is formed at a position, facing the gap, of the carrier layer 11, and is also used for transmitting light. The light quantity of light transmission belt 14 is big relatively the light quantity of light transmission hole 13 in this embodiment for the luminance of lamps and lanterns no longer concentrates on the lamps and lanterns bottom, and the light that combines the reflectance of reflectance coating 12 again and let light transmission belt 14 and light transmission hole 13 permeate out carries out multiple reflection through reflectance coating 12 surfaces and can make light more even, lets lamps and lanterns keep even illumination intensity.

In this embodiment, in order to realize light transmission, the carrier layer 11 may adopt an integral transparent structure, and light emitted from the light source is irradiated onto the light transmission holes 13 of the reflective film 12 through the transparent carrier layer 11; in addition, the carrier layer 11 may also adopt a partially transparent structure, that is, the carrier layer 11 is only transparent at the position of the light-transmitting strip 14 and the position opposite to the light-transmitting hole 13, and the rest positions may be transparent or non-transparent according to actual conditions, and at this time, the light emitted by the light source can also be emitted through the light-transmitting hole 13; in addition, the carrier layer 11 can also transmit light by means of hole opening, that is, through holes are formed in the light transmitting belt 14 of the non-transparent carrier layer 11 and the positions opposite to the light transmitting holes 13, and the purpose of light transmission can also be achieved. In this embodiment, the carrier layer 11 is a transparent PET layer, the reflective film 12 is a metal layer structure, and after the reflective film 12 is attached to the carrier layer 11, part of light beams of the light source can penetrate through the PET layer and pass through the light holes 13 of the reflective film 12, and part of the light beams are reflected for multiple times through the non-light-transmitting areas outside the light holes 13 of the reflective film 12, so that the light can be collected at the top of the carrier with a conical structure after being reflected for multiple times, and the brightness of the top of the lamp is increased, thereby reducing the brightness difference between the upper end and the lower end of the lamp, and further realizing uniform illumination intensity.

In this embodiment, the areas of the reflective films 12 distributed on both sides of the light-transmitting strip 14 are different, in this embodiment, the area of one reflective film 12 close to the light source is larger than the area of one reflective film 12 far away from the light source, that is, the light source of this embodiment is arranged at the bottom of the carrier of the cone-shaped structure, so the area of the reflective film 12 located below the carrier is larger than the area of the reflective film 12 located above the carrier, and the number of the light-transmitting holes 13 of one reflective film 12 with a relatively smaller area is smaller than the number of the light-transmitting holes 13 of one reflective film 12 with a relatively larger area, and the distribution rule of the light-transmitting holes 13 of two reflective films 12 in this embodiment makes the light-transmitting strip 14 between two reflective films 12 closer to the top of the carrier of the cone-shaped structure; at this time, because the lower part of the carrier is closer to the light source, the light source reflects in the non-light-transmitting area inside the reflective film 12, and a part of light energy can be weakened after reflection, so that the intensity of light emitted from the light-transmitting holes 13 of the reflective film 12 positioned below can be weakened, and after the light source reflects for multiple times through the non-light-transmitting area inside the reflective film 12, light beams can be gathered at the top of the conical structure, so that the intensity of light emitted from the light-transmitting holes 13 of the reflective film 12 positioned above can be enhanced, therefore, the number of the light-transmitting holes 13 of the reflective film 12 positioned below is greater than that of the light-transmitting holes 13 of the reflective film 12 positioned above, so that the light-transmitting degree below the lamp is greater, and the lamp can maintain relatively uniform illumination intensity from the bottom to the top.
