[0030] figure 1 A general cross-sectional view of the LED lighting device according to the first embodiment of the present invention is schematically shown.
[0031] Such as figure 1 As shown, the LED lighting device according to the first embodiment of the present invention includes: an LED light-emitting chip placement base 1 , an LED light-emitting chip 2 , a side housing 3 , and a top lens unit 4 .
[0032] Wherein, the LED light-emitting chip 2 is arranged on the LED light-emitting chip placement substrate 1 .
[0033] The side casing 3 is arranged on the LED light-emitting chip mounting base 1 and surrounds the LED light-emitting chip 2 .
[0034] Moreover, the top lens unit 4 is arranged on the top of the side housing 3, so that the LED light-emitting chip placement base 1, the side housing 3, and the top lens unit 4 jointly form a closed space; and the closed space is in a vacuum stateVacuum state, thereby improving luminous efficiency, or filled with inert gas, th...

[0040] figure 2 A general cross-sectional view of the LED lighting device according to the second embodiment of the present invention is schematically shown.
[0041] Such as figure 2 As shown, the LED lighting device according to the second embodiment of the present invention is different from the first embodiment in that only the inner surface of the convex lens of the top lens unit 4 is coated with a phosphor layer 52, and as the The outer surface of the convex lens of the top lens unit 4 is not coated with phosphor layer.
[0042] Since the phosphor layer 52 is coated on the inner surface of the convex lens serving as the top lens unit 4 , it can effectively prevent the phosphor layer from falling off due to external influences.

[0045] Such as image 3 As shown, the LED lighting device according to the third embodiment of the present invention is different from the first embodiment in that the LED light-emitting chip 2 is not mounted on the surface of the LED light-emitting chip placement substrate 1, but is embedded in the LED light-emitting chip The mounting base 1, wherein the light-emitting surface of the LED light emitting chip 2 is exposed from the surface of the mounting base 1 of the LED light emitting chip.
[0046] At this time, the LED light emitting chip 2 is still arranged at the focal point of the convex lens serving as the top lens unit 4 .
[0047] The LED lighting device according to the third embodiment of the present invention can make the installation of the LED light emitting chip 2 more stable.

Abstract
The invention provides LED (light emitting diode) lighting equipment. The lighting equipment comprises a supporting piece and an LED lighting device, wherein the LED lighting device comprises an LED light emitting chip placement substrate, an LED light emitting chip, a side shell and a top lens unit; the LED light emitting chip is arranged on the LED light emitting chip placement substrate; the side shell is arranged on the LED light emitting chip placement substrate and surrounds the LED light emitting chip; the top lens unit is arranged at the top of the side shell, thus the LED light emitting chip placement substrate, the side shell and the top lens unit jointly form a closed space; the closed space is in a vacuum state or is filled with inert gases; the top lens unit is a convex lens; a fluorescent powder layer is coated on the surface of the convex lens as the top lens unit; and the LED light emitting chip is arranged on the focal point of the convex lens as the top lens unit.
Description
technical field [0001] The present invention relates to the lighting field, and more specifically, the present invention relates to an LED lighting device. Background technique [0002] LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electrical energy into light energy. The heart of LED is a semiconductor chip, and one end of semiconductor chip is attached on a support (as negative pole), and the other end of semiconductor chip connects the positive pole of power supply, and whole chip is encapsulated by epoxy resin. [0003] Semiconductorwafer is made up of two parts, and a part is P-type semiconductor, and inside it, hole occupies an leading position, and the other end of semiconductor wafer is N-type semiconductor, is mainly electron here. Time these two kinds of semiconductors couple together, between them, just form a "P-N junction". [0004] When electric current acts on this chip by wire time, electron will be pushed to P ...
