Lamp assembly
First Claim
1. A lamp assembly comprising:
- a light guide member comprisinga light-emitting surface,a concave surface opposite to the light-emitting surface,a light incident surface connected between the light emitting surface and the concave surface,a groove defined in the concave surface, the groove extending along a lengthwise direction of the light guide member, anda plurality of light scattering structures arranged on the concave surface;
a light reflective member comprising a reflective surface opposite to the concave surface of the light guide member, wherein the light reflective member comprises a protrusion protruding from the reflective surface, the protrusion extending in a lengthwise direction of the light reflective member and engaged in the groove in the concave surface; and
a light source arranged adjacent to the light incident surface of the light guide member, the light source comprising a circuit board, a plurality of light emitting diodes, and two contact pins, the light emitting diodes electrically mounted on the circuit board and facing toward the light incident surface, the contact pins electrically connected to the circuit board and extending in a direction away from the light incident surface for electrical connection to a power source.

Abstract
An exemplary lamp assembly includes a light guide member, a light reflective member and a light source. The light guide member includes a light-emitting surface, a concave surface opposite to the light-emitting surface, and a light incident surface connected between the light emitting surface and the concave surface. The light reflective member includes a reflective surface opposite to the concave surface of the light guide member. The light source is arranged adjacent to the light incident surface of the light guide member. The light source includes a circuit board, a plurality of light emitting diodes, and two contact pins. The light emitting diodes are electrically mounted on the circuit board and face toward the light incident surface. The contact pins are electrically connected to the circuit board and extend in a direction away from the light incident surface for electrical connection to a power source.
