Abstract
Various examples of a lamp that produces omnidirectional light are described. The lamp may include a light-emission module. The light-emission module may include a substrate having a first primary surface. The first primary surface of the substrate may define a first horizontal plane that is substantially perpendicular to a longitudinal axis of the lamp. The light-emission module may also include at least one first light source and at least one second light source disposed on the first primary surface of the substrate. Each of the at least one second light source may include a light-emitting surface at an individually adjustable angle with respect to the first horizontal plane.
Claims20
A lamp, comprising:
- a light-emission module, comprising:
- a substrate having a first primary surface defining a first horizontal plane that is substantially perpendicular to a longitudinal axis of the lamp;
- and
- at least one first light source and at least one second light source disposed on the first primary surface of the substrate, the at least one second light source having a light-emitting surface at an individually adjustable angle with respect to the first horizontal plane.
A lamp, comprising:
- a light-emission module, comprising:
- a substrate having a first primary surface and a second primary surface opposite to the first primary surface, the first primary surface of the substrate defining a first horizontal plane that is substantially perpendicular to a longitudinal axis of the lamp, the second primary surface of the substrate defining a second horizontal plane that is substantially perpendicular to the longitudinal axis of the lamp;
- at least one first light source disposed on the first primary surface of the substrate, the at least one first light source having a light-emitting surface at a non-adjustable angle with respect to the first horizontal plane;
- and
- at least one second light source disposed on the second primary surface of the substrate, the at least one second light source having a light-emitting surface at an individually adjustable angle with respect to the second horizontal plane, wherein the angle of the light-emitting surface of the at least one second light source is greater than 0 degree with respect to the second horizontal plane.
A lamp, comprising:
- a light-emission module, comprising:
- a substrate having a first primary surface and a second primary surface opposite to the first primary surface, the first primary surface of the substrate defining a first horizontal plane that is substantially perpendicular to a longitudinal axis of the lamp;
- at least one first light source disposed on the first primary surface of the substrate, the at least one first light source having a light-emitting surface at an individually adjustable angle with respect to the first horizontal plane;
- and
- at least one second light source disposed on the second primary surface of the substrate, the second primary surface of the substrate defining a second horizontal plane that is substantially perpendicular to the longitudinal axis of the lamp, the at least one second light source having a light-emitting surface at an individually adjustable angle with respect to the second horizontal plane;
- and
- a heat-dissipation module, comprising:
- a finned portion;
- and
- a platform portion protruding from the finned portion along the longitudinal axis of the lamp, the platform portion having a mounting surface on which the second primary surface of the substrate of the light-emission module is mounted.
