Embodiment Construction

[0036] figure 1 The work light 1 is shown in an exploded perspective view.

[0037] The work light 1 comprises a housing 2 mounted on a support 3 which in turn is intended to be mounted on a vehicle V, in particular a heavy vehicle such as a truck. For example, the support 3 may be fastened to the vehicle V and the housing 2 may be pivotally mounted on the support 3 about the axis 5 . The pivot axis 5 can be horizontal and directed transversely, so that the light beam generated by the work light 1 can be tilted towards the ground.

[0038] The housing may have a bottom wall 4 and an open face 6 opposite the bottom wall 4 .

[0039] The work light 1 comprises a plurality of light sources 10 which may generally consist of LEDs (Light Emitting Diodes). For example, there may be five to ten light sources in the work light 1 . The light source 10 may comprise a base 11 and a cover 12 and have an emission axis 13 . The light source 10 is arranged in the housing 2 , for example,...

Abstract

The invention provides a lens (15). The input face (20) of the lens (15) comprises: an upper portion (22) configured to divert light rays such that the light rays are substantially parallel to a horizontal mid-plane (P2); and a lower portion (23) configured to reduce a vertical field angle (alpha) of the light beam along the vertical axis (Z). The output face (30) of the lens (15) comprises: a central vertical portion (31) substantially planar and orthogonal to the optical axis (16); lateral portions (32) located on both sides of the central vertical portion (31), the lateral portions (32) being configured to divert each light in the direction of the vertical median plane (P1) according to a deflection amplitude, the deflection amplitude increasing as the point of incidence of the light on said lateral portions (32) approaches the vertical median plane (P1).

Description

technical field [0001] The invention relates to a lens intended to be placed on the path of light rays emitted by a light source. The invention also relates to a work light comprising a plurality of light sources and such a lens arranged opposite at least one of these light sources. The invention also relates to a vehicle, in particular a heavy vehicle such as a truck, comprising at least one such work light. Background technique [0002] Some vehicles are equipped with work lights, ie housings equipped with light sources, such as spotlights, suitable for illuminating the desired area. More particularly, this relates to heavy vehicles such as trucks, in particular vehicles comprising a rear container from which items should be loaded / unloaded. In particular, these vehicles may include delivery vehicles, whether refrigerated or not, equipped with liftgates, garbage trucks, and the like. In order to carry out these loading / unloading operations correctly without any particul...
