Problems solved by technology

The light guide element in the prior art is equivalent to a light concentrator, which is composed of several thick-walled units, and the connection between several thick-walled units is uneven, resulting in a step difference when lighting the light source; similarly, when using When reflecting the mirror, it will also produce dark areas one by one to make the luminous effect worse
Therefore, the above two light guide elements have the disadvantages of poor uniformity, discontinuous lighting, and direct bright spots when the light source is directly illuminated. In addition, when the light guide element is applied to a lamp, its obvious separation unit

Embodiment 1

[0033] Such as figure 1 and figure 2 As shown, the present embodiment provides a lamp, which includes a photoconductor 3 and a light guide element 4 with a thickness in the range of 2mm-5mm. The photoconductor 3 preferably adopts a cylindrical structure. The first light source group 1 and the second light source group 2 arranged on the light guide element 4, wherein the first light source group 1 is located in the length direction of the photoconductor 3 ( figure 1 Each first light source group 1 includes at least one light source. In this embodiment, the above-mentioned first light source group 1 is located at one end of the length direction of the photoconductor 3 and includes only one light source. The distance between the first light source group 1 and the photoconductor 3 is very short, about 0.5 mm; The light-emitting surface on the front side of the light element 4 emits light.

[0034] The number of photoconductors 3 is not limited to the one in this embodiment. If...

Embodiment 2

[0047] The difference between this embodiment and the first embodiment lies in that the structure of the optical element is different, and the positional relationship between the light guide 3 and the light guide element 4 is different. Specifically, such as Figure 7 As shown, the lamp in this embodiment includes a photoconductor 3, a first light source group 1, a second light source group 2, and a light guide element 4 with a thickness in the range of 2mm-5mm. The first light source group in this embodiment 1 is located in the length direction of the photoconductor 3 ( Figure 6 L direction shown in ) and includes only one light source, the distance between the first light source group 1 and the photoconductor 3 is very short, about 0.5 mm. The light guide element 4 in this embodiment is closed, and a through hole is provided in it, and an incident surface is provided on its rear side, and the incident surface forms a placement groove, wherein the second light source group ...

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that in this embodiment, the light guide element 4 is made of a material with scattering properties or its longitudinal section adopts a second optical pattern of other shapes.

[0053] Such as Figure 6 As shown, the longitudinal section of the first optical pattern on the light guide 3 is arranged in a triangle, and the light guide element 4 is made of a material with scattering properties, which may be polycarbonate or the like. Figure 6 The shadow part of the light guide element 4 is opaque, the purpose is to prevent the light rays of the second light source group 2 from crossing each other when propagating in the light guide element 4, resulting in uneven luminescence, and improving the heat dissipation characteristics of the light guide element 4, Make it glow more evenly.

[0054] Such as Figure 7 As shown, the longitudinal section of the first optical pattern on the light guide 3 ado...

Abstract

The invention relates to the field of lighting control, and discloses a lamp and a lighting control method thereof. The lamp comprises an optical conductor, a first light source set and a second lightsource set; the first light source set is arranged at the end of the optical conductor and comprises an optical conducting element with the thickness ranging from 2 mm to 5 mm, the second light source set is arranged on the side face of the optical conducting element and comprises multiple light sources, and the optical conducting element and the optical conducting part are arranged front and back. The lamp is adopted to achieve different lighting effects of the lamp, the lamp space is saved, uniform lighting of the light-emitting area is achieved, timing-sequence lighting of the light-emitting area can be achieved, mixed lighting of the light-emitting area can be achieved, and the lamp has the good light-emitting uniformity, can achieve continuous light emitting, cannot generate direct shooting hot spots and enables a user not to seed an inner obvious separation unit.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lamp and a lighting control method thereof. Background technique [0002] In the headlights or taillights of motor vehicles, currently used optical devices that can simultaneously realize the flashing or uniform lighting of lamps include light guides and light guide elements with a wall thickness of 20 mm to 30 mm, or light guides and reflectors. The light guide element in the prior art is equivalent to a light concentrator, which is composed of several thick-walled units, and the connection between several thick-walled units is uneven, resulting in a step difference when lighting the light source; similarly, when using When reflecting the mirror, it will also produce dark areas one by one to make the luminous effect worse. Therefore, the above two light guide elements have the disadvantages of poor uniformity, discontinuous lighting, and direct bright spots when the light so...
