Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle warning light technical field especially according to external illumination condition realizes two kinds of brightness level's blind spot warning light. BACKGROUND

[0002] Through the analysis of increasingly frequent and serious traffic accidents, the driver's blind area is an important inducement of traffic accidents, therefore, the blind area monitoring warning system as part of the active safety technology, more and more becomes the "standard configuration" of many vehicle types, and it is analyzed that it will become a mandatory requirement.

[0003] GB / T 39265-2020 "Road vehicles - Blind spot detection (BSD) systems - Performance requirements and test methods" specifies various activation conditions for blind spot monitoring and early warning in detail, but there is no clear requirement for the brightness of the early warning light. ECER151, R159 regulations also make clear requirements and test methods for blind spot monitoring system (BSIS) and pedestrian and bicycle rider movement monitoring system (MOIS), but the brightness of the warning light is only "clearly visible during the day / night".

[0004] According to the technical requirements of domestic vehicle manufacturers, the brightness requirement of the warning light is also a wide range; the requirement of "visibility" is that the brightness is not less than 5000nit (cd / m2), and the requirement of preventing glare is that the brightness is less than 20000nit (cd / m2). However, the perception of brightness by the human eye is different under different lighting environments. When the external environment light is relatively bright, and the brightness of the warning light is too weak, the excitability of the retina cells is insufficient, the visual response process is slow, and it is easy to cause visual decline and visual fatigue; when the external environment light is relatively dark, and the brightness of the warning light is too strong, the strong light will produce a dazzling feeling, stimulate the retina, and cause a decrease in visual function, eye fatigue, and even eye pain. In summary, a single wide brightness range is not conducive to activating the participation of the driver in various environments and achieving the expected warning effect. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the utility model provides a blind spot warning light which realizes two brightness levels according to external illumination conditions, and solves the technical problem that a single warning light brightness range is not conducive to activating the participation of the driver in various environments.

[0006] To solve the above technical problems, the utility model provides the following technical scheme: a blind spot warning light which realizes two brightness levels according to external illumination conditions, the blind spot warning light comprises an upper lamp shell and a lower lamp shell, and the upper lamp shell and the lower lamp shell are connected by ultrasonic welding;

[0007] A plurality of groups of indicating lamps are arranged on the upper lamp shell, and a transparent cover for protecting the indicating lamps is further arranged on the upper lamp shell.

[0008] The transparent cover of the blind spot warning lamp can be attached to the rearview mirror of the vehicle, thereby achieving installation and fixation of the blind spot warning lamp.

[0009] Preferably, a driving circuit board is encapsulated in the lower lamp shell, and the driving circuit board is programmed with a driving circuit for lighting the indicating lamps.

[0010] Preferably, a plug-in interface is arranged on the lower lamp shell, and the plug-in interface can be arranged vertically or horizontally.

[0011] The blind spot warning lamp of the utility model does not need to be coated with sealing glue to achieve IP65 level waterproofing, and the waterproofing performance is more stable; and the blind spot warning lamp connector is directly integrated on the lamp shell, without the need to fix the connector of the wire-to-wire connector, the plug-in is stable, and the shock resistance is good; meanwhile, the blind spot warning lamp provides two brightness levels, which ensures that the indicating lamps are still clear under high light intensity, avoids excessive stimulation of the human eye under low light intensity, and reduces discomfort.
