Description

Wide size signal lamp for vehicle

Technical Field

The utility model relates to the technical field of vehicle signal lamps, in particular to a vehicle wide-size signal lamp.

Background

The automotive signal lamp is used to make a pedestrian or a vehicle on a road located at a certain distance clearly recognize a light signal. The bulb parameters of the signal lamp, the intensity of the emitted light, the spread angle of the light beam, and the area of the emitted light, the color of the light, etc., are all important. In order to easily recognize an optical signal at night with a dark background, the luminous intensity is generally only between several candelas to several tens of candelas for signal lamps used only at night such as position lamps, outline marker lamps, stop lamps, and the like. If the lamp light is used in any day and night, such as a turn light, a brake light and the like, the light intensity of the lamp light is more than hundreds of candelas. In order to prevent such signal lamps from generating glare when working at night, some signal lamps adopt two working conditions of day and night besides the limitation on the maximum luminous intensity. For most car signal lights that are perceived close, the matching between the light emitting area and the specified light emitting intensity must also be considered to prevent glare due to excessive brightness. Meanwhile, the requirement on uniformity of light is higher for the signal lamp with wide size in the transverse direction.

Detailed Description

In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings and the specific embodiments.

Referring to fig. 1-5, fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a schematic view of A-A in FIG. 1; FIG. 3 is a schematic diagram of a PCBA circuit board; FIG. 4 is a schematic view of a thick-walled light guide; fig. 5 is an appearance diagram of the signal lamp.

The utility model provides a vehicle wide-size signal lamp, which is used for providing a clearly recognizable light signal for pedestrians or vehicles on a road at a certain distance; the light guide comprises a PCBA circuit board 1 which is arranged on the inner side of a vehicle body and is used as a vehicle lamp core, and a thick-wall light guide 2 which is arranged below the PCBA circuit board 1 and is used for refracting light.

The width of the PCBA circuit board 1 and the thick-wall light guide 2 in the left and right direction is the same as that of the vehicle headlamp; the thick-walled light guide 2 is divided into three parts in the left-right width direction according to the difference in vertical width in the left-right direction, including a large-size width part 21 where the width in the left-right direction is the largest, a small-size width part 22 where the vertical width in the middle is the smallest, and a medium-size width part 23 where the vertical width in the right-hand direction is between the largest and the smallest.

A row of LED lamp beads 11 are uniformly arranged on the lower side surface of the PCBA circuit board 1 at the same interval distance along the width direction of the vehicle lamp and are used for providing a light source for the signal lamp; PCBA circuit board 1's downside is still fixed be provided with thick wall light guide 2 be used for with the light that LED lamp pearl 11 sent is refracted and is used, makes thereby thick wall light guide 2 brightens and provides the discernment degree for pedestrian and vehicle.
