Embodiment Construction

[0022] figure 1 It is a schematic diagram of a light emitting device according to an embodiment of the present invention. Please refer to figure 1 , the light emitting device 100 of this embodiment includes a carrier 110 , a light emitting diode element 120 and a colored lens 130 . The LED element 120 is disposed on the carrier 110 and electrically connected to the carrier 110 . In this embodiment, the carrier 110 is, for example, a printed circuit board or other substrates properly configured with a plurality of circuit lines. In addition, the light emitting diode element 120 is, for example, a white light emitting diode package, and its packaging method may be formed by using a blue light emitting diode chip 122 with a yellow phosphorescent material 124 , but is not limited thereto. In one embodiment, the LED element 120 can also be an LED chip of other colors and matched with appropriate phosphor or phosphor, so that the LED element 120 can provide white light or light o...

Abstract

The invention provides a light-emitting device which comprises a loader, a light-emitting diode (LED) element and a coloured lens. The LED element is disposed on the loader and electrically connected to the loader. The coloured lens is disposed on the LED element, and the colour of the coloured lens is changed gradually in a direction far away the LED element, wherein a light beam supplied by the LED element is transmitted to the coloured lens and radiated out of the light-emitting device.

Description

technical field [0001] The present invention relates to a light emitting device, and in particular to a light emitting device with better optical performance. Background technique [0002] Light-emitting diode is a light-emitting element composed of semiconductor materials containing III-V elements, and light-emitting diodes have advantages such as long life, small size, high shock resistance, low heat generation and low power consumption, so they have been widely used Indicators or light sources in household and various equipment. In recent years, light-emitting diodes have developed towards multi-color and high brightness, so their application fields have been extended to large outdoor signage, traffic lights and related fields. In the future, light-emitting diodes may even become the main lighting source with both power saving and environmental protection functions. [0003] For example, most of the current packaging methods for high-power white light-emitting diodes ar...
