Embodiment Construction

[0067] The light-emitting diode device of the present invention will be explained through the examples below, however, the description of the examples is only for explaining the present invention, rather than limiting the present invention. In the following embodiments and drawings, elements not directly related to the present invention have been omitted and not shown; and the size and relative positional relationship of each element in the drawings is only for illustrative purposes, and is not intended to limit actual proportions and sizes. size.

[0068] Such as Figure 1A to Figure 1CAs shown, the first embodiment of the present invention is a light emitting diode (light emitting diode, LED) device 1 for a micro projection system. The light emitting diode device 1 includes a bottom substrate 101, an anode portion 103, and two cathode portions 105 , an LED chip 107 , a surrounding substrate 109 and a light-transmitting element 111 . Since the LED device 1 of this embodimen...

Abstract

The invention provides a light emitting diode device for a miniature projection system, comprising a bottom substrate, an anode part, at least one cathode part, at least one light emitting diode (LED) chip and a light-transmitting element, wherein the anode part and the at least cathode part are respectively arranged on the bottom substrate; the at least LED chip is arranged on the anode part and is electrically connected with the at least cathode part; and the light-transmitting element is arranged on the bottom substrate in a covering manner so as to define a cavity. Or the light emitting diode device can comprise a surrounding substrate which is provided with a surrounding part and a hollow part; and the light-transmitting element is directly arranged on the surrounding substrate instead of the bottom substrate in a covering manner so as to define the cavity by the hollow part.

Description

technical field [0001] The present invention relates to a light emitting diode device, in particular to a light emitting diode device applicable to a micro projection system, so as to make the volume of the micro projection system more miniaturized. Background technique [0002] In order to meet the current market demand for thin, light and small electronic products, traditional projectors have also begun to be miniaturized. The use requirement of the Pico Projector is set to be easy to carry around. It is not only made into a portable Pico Projector, but also applied to various existing electronic products, such as built-in mobile phones and multimedia players. , personal digital assistant (Personal Digital Assistant, PDA), notebook computer, etc., so as to expand the functional diversity of electronic products. [0003] Based on the structurally simplified and lightweight requirements and the optical brightness performance, currently micro-projectors mostly use red, green...
