Problems solved by technology

If an excessive voltage is provided and then stepped down through the voltage divider resistor, and then supplied to the LED, the voltage divider resistor will not only cause considerable power loss under long-term use, but also easily lead to high temperature and affect the surrounding components. stability
Therefore, in the known technology, an additional power supply must be configured to directly provide 3V voltage and 20mA current to the LED, but this method will lead to a substantial increase in cost
[0004] On the other hand, organic light emitting diodes (Organic Light Emitting Diode, referred to as OLED) have the advantages of low driving voltage and low driving current compared with LEDs, but OLEDs are easily damaged by environmental influences, such as moisture and failure

Embodiment Construction

[0024] In the known technology, the driving current of the LED is relatively high, which not only causes a waste of power, but also requires an additional power supply for the LED to use. In view of this, an embodiment of the present invention provides a light-emitting device, which uses an OLED element as a light-emitting source, so that power consumption can be effectively saved. In addition, with the light-transmitting body, lead frame, pins, and multiple leads, not only can the OLED element be properly protected, thereby extending the life of the OLED element, but also making the light-emitting device easier to use. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings illustrate exemplary embodiments of the present invention, wherein the same reference numerals indicate the same or similar steps.

Abstract

The invention discloses a luminous device, which comprises a transparent body, a lead frame, a plurality of pins, an organic light-emitting diode element and a plurality of lead wires. The plurality of pins are inserted into the lead frame, and parts of the pins penetrate an enclosed space. The organic light-emitting diode element is configured on the lead frame and positioned in the enclosed space. The plurality of lead wires are positioned in the enclosed space, and are respectively connected with the pins and the organic light-emitting diode element. The transparent body can form the enclosed space. Therefore, the service life of the organic light-emitting diode element can be prolonged, and the power consumption of the luminous device can be reduced.

Description

Technical field [0001] The present invention relates to a light emitting device, and more particularly to a structure of the light emitting device. Background technique [0002] Light Emitting Diode (LED for short) is a semiconductor element. At first, it was mostly used as indicator light, display board, etc.; with the appearance of white light emitting diode, it was also used as lighting. It is a new type of light source in the 21st century. Compared with traditional light sources, LED has the advantages of high efficiency, long life, and not easy to break. When the forward voltage is applied, the LED can emit monochromatic, discontinuous light, which is a kind of electroluminescence effect. Changing the chemical composition of the semiconductor material used can make the LED emit light in the near ultraviolet, visible light or infrared. [0003] It is worth mentioning that the driving voltage and driving current of the LED are about 3V and 20mA. If an excessive voltage is pr...
