In the existing signal lamp, a light source device is arranged on a focus of a reflector, so that the light source device is directly exposed in a highly visible range of human eyes, and the attractiveness of the signal lamp is influenced. In addition, when the light source device is operated and lighted, the human eyes see obvious bright spots, and the visual effect is not good. In view of this, the utility model provides a signal lamp, referring to fig. 1 to 3, in an embodiment of the present invention, this signal lamp 100 includes:
the mounting shell 110 comprises a shell body 111 and a first side wall 112 which are arranged in an intersecting manner, a reflecting surface 113 is arranged on the shell body 111, and the mounting shell 110 is provided with a light emitting opening 110a which is arranged opposite to the reflecting surface 113; and
the light source 120 is arranged on one side of the first side wall 112, which is far away from the reflecting surface 113, and the first side wall 112 is provided with a light ray through hole 112a corresponding to the light source 120;
in the direction toward the light emitting opening 110a, the reflecting surface 113 extends in the direction away from the light source 120 and is arranged in a step-shaped curved surface, the step-shaped curved surface includes a plurality of reflecting curved surfaces 1131, and at least part of the light emitted by the light source 120 is reflected by the reflecting curved surfaces 1131 and then emitted toward the light emitting opening 110 a;
the focal point 201 of at least one curved reflecting surface 1131 is located on the light source 120, and the focal points 201 of at least two curved reflecting surfaces 1131 are disposed at different points in space.
In the technical solution of the present invention, the light source 120 can be prevented from being directly seen by human eyes by hiding the light source 120 under the light passing hole 112 a; moreover, the light emitted from the light source 120 is reflected by the reflective curved surface 1131 and then emitted to the light emitting opening 110a, but not directly emitted to the light emitting opening 110a, so that when the human eyes look at the signal lamp 100 from the main viewing angle, the human eyes do not feel obvious bright spots, thereby improving the visual effect of the signal lamp 100. Without loss of generality, the light emitted by the signal lamp 100 should be distributed in a scattering shape, and cannot have a strong light-gathering effect, so as to meet the light distribution requirement of the lamp under the national standard. The focal points 201 of the plurality of reflective curved surfaces 1131 are not overlapped, which means that the light source 120 may not completely cover all the focal points 201, that is, at least a part of the light emitted by the light source 120 is reflected by the partially reflective curved surface 1131 and then emitted to the light emitting opening 110a at a certain scattering angle, so as to avoid a strong light condensing effect, thereby meeting the national standard requirements.
Optionally, the curved reflecting surface 1131 is disposed in a paraboloid. By the parabolic arrangement, the incident angle and the reflection angle of the light on the reflective curved surface 1131 can be better designed and adjusted, that is, the angle at which the light is emitted to the light emitting opening 110a and to the outside of the signal lamp 100 is controlled, so that the light intensity of the signal lamp 100 meets the national standard. However, the design is not limited thereto, and in other embodiments, the curved reflecting surface 1131 may also be disposed in an ellipsoidal shape.
Referring to fig. 2 and 3, optionally, the focal points 201 of all the curved reflective surfaces 1131 are spatially formed into a set of focal points 201, and the light source 120 is disposed on a focal point 201 located in the middle of the set of focal points 201. The light source 120 is selectively disposed on the central focal point 201, so that the area with a larger light intensity in the light beam emitted by the signal lamp 100 falls on the middle of the reflective surface 113, rather than on the edge of the reflective surface 113, and further the light intensity of the signal lamp 100 gradually weakens from the middle to the edge, so that the overall light emitting effect of the signal lamp 100 is better.
Optionally, a plurality of parabolic sections are formed by dividing a reference paraboloid 202, the parabolic sections are distributed at intervals along the direction of an axis 203 of the reference paraboloid 202, and the axis 203 is arranged to penetrate through the light source 120; the parabolic section corresponding to the focus of the light source 120 is set as a boundary parabolic section, and a plurality of parabolic sections located at the outer side of the boundary parabolic section are gradually far away from the reference parabolic surface 202 away from the light emitting opening 110a in the direction far away from the light source 120 by taking the boundary parabolic section as a boundary; a plurality of parabolic sections located inside the boundary parabolic section in a direction approaching the light source 120, being disposed gradually away from the reference parabolic surface 202 toward the light emission opening 110 a; the parabolic section is a curved reflective surface 1131. Through the structural arrangement, the overall size of the reflecting surface 113 in the direction of the axis 203 can be obviously shortened, and the size miniaturization design of the signal lamp 100 is further facilitated, so that the signal lamp can be applied to a compact arrangement space on an automobile. However, the design is not limited thereto, and in other embodiments, the reflecting surface may also be composed of a plurality of paraboloidal sections with coincident axes and non-coincident focuses.
Optionally, the axis 203 of the reference paraboloid 202 is parallel to the wall direction of the first sidewall 112. It should be noted that parallel refers to parallel and near parallel. By arranging the light sources in parallel, more light can be emitted to the outside of the signal lamp 100 under the same structural size of the reflecting surface 113.
Alternatively, the distance between the focal points 201 of two adjacent curved reflecting surfaces 1131 is set between 0.4mm and 0.8 mm. The spacing between two adjacent focal spots 201 may be 0.4mm, or 0.5mm, or 0.7 mm. If the distance between two adjacent focuses 201 is set too large, the scattering angle of the signal lamp 100 is too large, and the light emitting power of the light source 120 required under the condition of meeting the national standard is larger, which wastes the light emitting power of the light source 120. If the distance between two adjacent focal points 201 is too small, the light-gathering effect is too strong, which does not meet the national standard requirements, and it is not favorable to reduce the size of the reflecting surface 113 in the direction of the axis 203, that is, it is not favorable to the size miniaturization design of the signal lamp 100.
Optionally, a transition surface 1132 is connected between two adjacent curved reflective surfaces 1131, and a height dimension of the transition surface 1132 is smaller than a height dimension of the curved reflective surface 1131. The ratio of the area of the reflective curved surface 1131 to the reflective surface 113 can be increased, and more light from the light source 120 can be reflected to the light emitting opening 110 a.
Optionally, the reflective surface 113 is prepared by a spraying and aluminum plating process. The reflection surface 113 manufactured by the spraying and aluminum plating processes has high reflectivity, that is, the light source 120 with the same luminous power can make the signal lamp 100 obtain higher luminous intensity. However, the design is not limited thereto, and in other embodiments, the reflective surface may be formed by directly stamping or machining an aluminum plate, or by spraying and silver plating.
To improve the service life of the signal light fixture 100, optionally, the light source 120 is an LED lamp bead. The LED lamp bead has the advantages of small volume, low power consumption, high brightness, low heat productivity and long service life, thereby being beneficial to the structural miniaturization design of the signal lamp 100, reducing the power consumption of the signal lamp 100 and prolonging the service life of the signal lamp 100. However, the design is not limited thereto, and in other embodiments, the light source may be a halogen lamp or a xenon lamp.
Further, the signal lamp 100 further includes a light-transmitting mask disposed at the light-emitting opening 110 a. The light-transmitting face shield may act as a dust shield and protect the internal components of the signal light fixture 100, such as the reflective surface 113, from impact damage.
Referring to fig. 1 and 2, it is understood that exterior signal lamps 100 of an automobile, such as turn signal lamps, running light and stop light, are generally shaped to extend in a certain direction, and the dimension in the extending direction is greater than the dimension in the width direction. In order to make the light emitting effect of the signal lamp 100 in different areas in the extension direction of the model more uniform, optionally, a plurality of reflecting surfaces 113, light passing holes 112a and light sources 120 are provided, and correspond to one another; the plurality of reflecting surfaces 113 are arranged along the extending direction of the first sidewall 112. The signal lamp 100 has a large overall light-emitting area formed by the plurality of reflecting surfaces 113, and the small light-emitting area corresponding to each reflecting surface 113 is provided with the light source 120, so that the light-emitting effect of the small light-emitting area is uniform, and on the basis, the light-emitting effects of the plurality of small light-emitting areas tend to be consistent, and the uniform light-emitting effect of the signal lamp 100 can be obtained.
It is understood that the exterior signal lamps 100 of the automobile, such as the turn signal lamp, the running light and the stop light, generally have irregular outlines after being shaped, and in order to enable the signal lamps 100 with irregular outlines to have a uniform light emitting effect, optionally, the housing body 111 further includes a second side wall 114 disposed opposite to the first side wall 112, and the first side wall 112 and the second side wall 114 are disposed in a staggered distribution along a direction perpendicular to the extending direction of the first side wall 112; the first sidewall 112 and the second sidewall 114 are each provided with a plurality of light passing holes 112 a.
Further, the signal lamp further includes a circuit board 140 disposed corresponding to the first sidewall 112 and the second sidewall 114, and the light source 120 is disposed on the circuit board 140. By integrating the light source 120 on the circuit board 140, the number of steps of assembling the light source 120 on the signal lamp is reduced, and the heat dissipation surface area of the light source 120 is increased. However, the design is not limited thereto, and in other embodiments, the light source may be disposed on the first sidewall and the second sidewall.
Optionally, the edge of the housing body 111 is extended with a cylindrical reinforcement bead in a direction towards the light emitting opening 110a, and the first and second side walls 112 and 114 are provided as opposite side walls of the cylindrical reinforcement bead. The cylindrical reinforcing flanging can improve the structural strength of the shell body 111, and further prevent the plastic deformation of the shell body 111 in the assembling and using processes, so that the service life of the signal lamp 100 is prolonged, and the later maintenance cost of the signal lamp 100 is reduced. However, the design is not limited thereto, and in other embodiments, the edge of the housing body may be extended with a cylindrical reinforcing flange in a direction away from the light emitting opening.
