Abstract

A lighting apparatus includes a carrier, a first light-emitting element, and a cover body. The carrier has a top surface. The first light-emitting element is formed on the top surface. The cover body covers the carrier and exposes the first light-emitting element. The lighting apparatus has a luminous flux greater than 350 lumens.

First claim

What is claimed is:

1 . A lighting apparatus, comprising:
a carrier having a top surface; a first light-emitting element formed on the top surface; and a cover body covering the carrier and exposing the first light-emitting element; wherein the lighting apparatus has a luminous flux greater than 350 lumens.

2 . The lighting apparatus according to claim 1 , wherein the lighting apparatus consumes a power ranging between 1˜5 Watt.

3 . The lighting apparatus according to claim 1 , wherein the carrier has an average temperature less than 120° C.

4 . The lighting apparatus according to claim 1 , further comprising a second light-emitting element formed on the carrier and overlapped with the first light-emitting element.

5 . The lighting apparatus according to claim 1 , further comprising a second light-emitting element formed on the carrier and connected to the first light-emitting element in parallel.

6 . The lighting apparatus according to claim 1 , wherein the cover body comprises a recess where the first light-emitting element is located in.

7 . The lighting apparatus according to claim 1 , wherein the cover body has a highest point and the first light-emitting element does not exceed the highest point.

8 . The lighting apparatus according to claim 1 , further comprising a support body having a bottom part and a side part.

9 . The lighting apparatus according to claim 8 , wherein the first light-emitting element comprises a plurality of light-emitting units formed on the bottom part.

10 . The lighting apparatus according to claim 1 , further comprising a center point of the carrier, a virtual circle with a center positioned at the center point, and a luminous intensity distributed on the virtual circle, wherein the luminous intensity is between 0˜2 cd.

11 . A lighting apparatus, comprising:
a carrier having a top surface; a light-emitting element formed on the top surface, comprising a bottom part and a side part; a cover element formed on the light-emitting element; and a cover body covering the carrier and exposing the first light-emitting element.

12 . The lighting apparatus according to claim 11 , wherein the cover element has a first end connected to the light-emitting element and a second end being coplanar with the top surface.

13 . The lighting apparatus according to claim 11 , further comprising a filler connected to the bottom part and the side part.

14 . The lighting apparatus according to claim 11 , wherein the light-emitting element comprises a plurality of light-emitting units, a filler covering the plurality of light-emitting units and a conductive structure connected to the cover element.
