Abstract
Official abstract text for this publication.
The present invention relates to an illumination device, including: a support member; and at least one first light source on the support member and at least one second light source on the support member, where the first light source has a first light distribution, the second light source has a second light distribution, and the first light distribution is different from the second light distribution.
First claim
Opening claim text (preview).
What we claim is: 1. An illumination device, comprising: a support member; at least one first light source on the support member and at least one second light source on the support member, wherein the at least one first light source has a first light distribution, the at least one second light source has a second light distribution, the first light distribution is different from the second light distribution, and the first light distribution and the second light distribution collectively form a composite light distribution; and a single adjustment member to directly adjust a current intensity ratio of current provided to the at least one first light source and the at least one second light source to modify the composite light distribution. 2. The illumination device according to claim 1 , wherein the composite light distribution of the illumination device is formed on the basis of a light output intensity ratio between the first light distribution and the second light distribution. 3. The illumination device according to claim 1 , comprising: a lampshade, wherein the first light source and the second light source are located inside the lampshade, and a light distribution of the illumination device is formed on the basis of an optical characteristic of the lampshade and a light output intensity ratio between the first light distribution and the second light distribution. 4. The illumination device according to claim 1 , wherein the first light distribution comprises a narrow beam angle distribution, and the second light distribution comprises a wide beam angle distribution. 5. The illumination device according to claim 4 , wherein the narrow beam angle distribution comprises a Lambertian distribution. 6. The illumination device according to claim 4 , wherein the wide beam angle distribution comprises a bat-wing distribution. 7. The illumination device according to claim 1 , wherein the first light source and the second light source respectively comprise an encapsulated LED. 8. The illumination device according to claim 1 , wherein a light output intensity corresponding to a light distribution is adjustable. 9. The illumination device according to claim 8 , wherein the light output intensity is adjusted by changing a quantity of light sources corresponding to a light distribution or a current intensity provided to a light source of a corresponding light distribution. 10. The illumination device according to claim 1 , wherein the first light source and the second light source are integrated into one lamp. 11. An illumination device, comprising: at least one first light source on a support member and at least one second light source on the support member, wherein the at least one first light source has a first light distribution, the at least one second light source has a second light distribution, the first light distribution is different from the second light distribution, and the first light distribution and the second light distribution collectively form a composite light distribution; and a dimmer to directly adjust a current intensity ratio of current provided to the at least one first light source and the at least one second light source to modify the composite light distribution.
