LED lighting device
First Claim
1. An LED lighting device, comprising:
- a circuit board;
at least one LED unit disposed on the circuit board along a predetermined direction, wherein each LED unit has a light-emitting surface configured to permit light emission toward a predetermined direction;
a spacing layer formed above the LED unit fully covering the light-emitting surface in the path of light emission; and
a waterproof layer wrapping the circuit board, the LED units, and the spacing layer, and in immediate contact with the lateral surface of the LED unit;
wherein the spacing layer is arranged between the light-emitting surface and the water-proof layer, and wherein the light emitted from each LED unit passes through the light-emitting surface, the spacing layer and the waterproof layer.

Abstract
An LED lighting device includes a circuit board, a plurality of LED units, a waterproof layer and a middle layer. The LED units are disposed on the circuit board by surface mounted way. The light beam emitted from the LED units emits from the light-emitting surface. The waterproof layer wraps the circuit board and the LED units. The middle layer is located between the light-emitting surface and the water-proof layer. The middle layer extends from a direction of the LED units being disposed on the circuit board so that the middle layer fully covers the light-emitting surface. The light beams passing through the light-emitting surface enters into the waterproof layer via the middle layer. Thereby, the middle layer is located between the LED units and the waterproof layer to make the color of the light beam be more uniform.
