Lighting apparatus and method of making thereof
A lighting apparatus and a method for manufacturing the same. A lighting apparatus is provided, including: a transparent portion including a first surface, a second surface and an edge connected to the first surface and the second surface, the edge including an inner surface with a preset shape; and a light source fixed on the transparent portion so that the inner surface receives light emitted by the light source and reflects it to at least one of the first surface and the second surface. The preset shape has a certain relationship with distribution of light emitted to the first surface and the second surface. The method for manufacturing just designs the preset shape during designing stage so as to satisfy requirements for distribution of the light emitted to the first surface and the second surface.
1. A lighting apparatus, comprising:
a transparent portion comprising a first surface, a second surface and an edge connected to the first surface and the second surface, the edge comprising an inner surface with a preset shape; and
a light source fixed so that the inner surface receives light emitted by the light source through the transparent portion and reflects it to at least one of the first surface and the second surface;
wherein the preset shape of the inner surface comprises:
a V-shape wherein the inner surface comprises a first reflective surface and a second reflective surface and one side of the first reflective surface is connected with one side of the second reflective surface to form a V: shape, either depressing toward the direction of the light source or protruding outwardly from the direction of the light source.
2. The lighting apparatus as recited in claim 1 , wherein the first surface of the transparent portion is in parallel with the second surface of the transparent portion.
3. The lighting apparatus as recited in claim 1 , wherein the light source comprises an LED diode.
4. The lighting apparatus as recited in claim 1 , wherein the inner surface is coated with a light reflective coating.
5. The lighting apparatus as recited in claim 1 , wherein the preset shape of the inner surface comprises at least one flat surface, the at least one flat surface angled with the first surface or the second surface at a preset angle which that is greater than 90° or less than 90°;
wherein the at least one flat surface of the inner surface comprises a first reflective surface, the first reflective surface having one side connected to the first surface of the transparent portion and having the other side connected to the second surface of the transparent portion.
6. The lighting apparatus as recited in claim 1 , wherein the light source is fixed on the transparent portion.
7. A method for manufacturing a lighting apparatus, comprising the following steps:
providing a transparent portion, the transparent portion comprising a first surface, a second surface and an edge connected with the first surface and the second surface;
forming an inner surface of the edge, the inner surface having a preset shape; and
providing a light source so that the inner surface receives light emitted by the light source through the transparent portion and reflects it to at least one of the first surface and the second surface;
wherein the preset shape of the inner surface comprises:
a V-shape wherein the inner surface comprises a first reflective surface and a second reflective surface and one side of the first reflective surface is connected with one side of the second reflective surface to form a V: shape, either depressing toward the direction of the light source or protruding outwardly from the direction of the light source.
8. The method for manufacturing a lighting apparatus as recited in claim 7 , wherein the light source is fixed on the transparent portion.
