Description

Bottom-striking type reflector device for preventing light scattering

Technical Field

The utility model relates to a downward-striking type reflector device for preventing light scattering, in particular to a technology applied to the field of lamps on vehicles, which is mainly used for shielding the light scattered by a reflector cup and keeping the light emergent direction, namely a technical scheme with excellent time-use property.

Background

Although lamps are essential in any field, it is a reflective cup on a vehicle, and a downward-type lamp is a type of lamp on a vehicle, as shown in fig. 11 and 12, which mainly has an inner arc surface 100, and when a light source 200 irradiates from top to bottom and emits light, part of the light is reflected by the inner arc surface 100 (as shown by arrows in fig. 12), so that the light is emitted forward at an infinite angle, see patent nos. M477966, M593345, I723304, or CN203836804U, US8920007, which are all commonly used.

With the scientific progress, the lighting part is also required day by day, even there is a special lighting brightness specification, for example, in the german bicycle lamp detection regulation specification, the main requirement is that the lamps have cut-off lines, so as not to hurt the eyes of the oncoming drivers, but the light field divided by the cut-off lines is divided into an upper light field and a lower light field, the optimal illumination of the upper and lower light fields near the cut-off lines is that the illumination 10M has a brightness of 20 or 30Lux or more, and the part farther away from the upper light field of the cut-off lines cannot exceed 2Lux, so that the illumination range is wide and the brightness distribution is uniform, and other light sources are more effectively used as the road lighting, the near lamp and the far lamp exist at the same time, really reaching the night bicycle lighting and warning safety, but the existing reflector cup does not meet the above specification, so many manufacturers will adjust the inward curved surface 100 shown in fig. 11 and 12 to be curved arcs with various angles, further, a hierarchical portion 300 is provided as shown in fig. 13 and 14.

However, the above-mentioned arrangement of the reflector shown in fig. 13 and 14 can effectively distinguish different light types such as high beam and low beam from each other and control the illumination brightness within the standard range, but there is a problem that the arrangement of the layer part 300, the light is easy to be irregularly scattered at the layer part 300 due to reflection (as the arrow in the figure indicates the light scattering), and the above-mentioned scattered light is easy to exceed 2Lux at the upper light field position far from the cut-off line under the mutual interference, so that the regulation cannot meet the standard of the regulation, and if the above-mentioned problem is to be improved, the adjustment must be performed at the position of the layer part 300, but the reflector must be manufactured by a machine with extremely high precision, such as an optical instrument, a high precision mold, etc., but the above-mentioned machine capable of manufacturing a high precision article is not very expensive, not all the manufacturers can pay the burden, so in order to avoid the scattered light generated at the hierarchical part from affecting the normally irradiated light, the manufacturers must solve and improve the above problem.

SUMMERY OF THE UTILITY MODEL

The main purpose of the present invention is to shield the scattered light generated at the level part when the lamp source inside the downward-lighting lamp is irradiated from top to bottom, so as to keep the reflection energy of the light after irradiation in a fixed direction, which improves the problem that the reflector cup in the prior art is easy to generate scattered light at the level part under the irradiation operation of the light, thereby affecting the upper light field position far away from the cut-off line to exceed 2Lux, and the manufacturing cost of the precise reflector cup is too expensive and difficult to be lost. Therefore, in order to achieve the above objects and effects and to improve the existing problems, the present invention provides a downward-striking type reflector device for preventing light scattering, comprising: a reflective cup, one side of which is concave to form a lighting chamber, and the inner wall of one side of the lighting chamber is provided with a plurality of reflective arc parts, and each reflective arc part is arranged side by side from left to right and up and down to form a plurality of transverse steps and a plurality of longitudinal steps; a shielding member, which comprises an outer frame part and a plurality of branch rib parts, wherein the outer frame part is respectively attached to the side wall surface of the illumination chamber, two ends of one branch rib part are connected with the outer frame part, other branch rib parts are sequentially arranged below the branch rib parts, and each branch rib part is attached to each transverse step; wherein, the two outer frame portions and the plurality of ribs are disposed in the illumination chamber of the reflector cup to shield the upward scattering of the light from the top to the bottom to the irradiation of each transverse step, so as to maintain the direction of the light reflected by each reflective arc portion.

According to the above description, the present invention has the advantages that the shielding member is installed in the illumination chamber of the reflective cup, the plurality of ribs are abutted against the respective lateral steps to shield the formed scattered light, so that the direction of the light source reflected by the reflective arcs can be maintained, the illumination light is not interfered by the scattered light to affect the external illumination when the general vehicle is illuminated during traveling, the riding safety is ensured, and the shielding member is installed in the illumination chamber, so that the reflective cup is not required to be finely adjusted to shield the scattered light during manufacturing, and the cost is unnecessarily increased. Therefore, the present invention is a creation with practical and progressive properties, which is worth popularizing in the industrial field and is public to the public.

Referring to the conventional reflector cup of fig. 14 again from the above description, under the irradiation of light, the light of the conventional reflector cup, after irradiating the inner curved surface 100, will have different light reflections according to the installation angle of the curved surface, wherein a part of the light will be reflected to the level part 300, and will be scattered more to the level part 300, so that the scattered light will irradiate towards a plurality of directions and interfere with each other, so that the irradiated light region will easily exceed 2Lux at the upper light field position far away from the cut-off line, so as to improve the above problem, please refer to fig. 1, 5 and 6 (wherein the solid line shown in fig. 6 is the light path, and the dotted line is the path after the light irradiates the transverse step 301), so that the shielding member 40 is installed in the irradiation chamber 101, and each rib 402 of the shielding member 40 abuts against each transverse step 301, the light reflected by the reflective arcs 30 meets the rib portions 402, so that no scattered light is generated, but the reflected light is irradiated toward the light outlet 103, and the angle of the arc surface is designed by matching with the arc surface of one side of each rib portion 402, so that the light can be irradiated toward the light outlet 103, and the light irradiated by the light source 20 can be intensively irradiated toward the light outlet 103 by the reflection of each reflective arc 30 and each rib portion 402, so as to keep the reflection direction of the light.
