Embodiment Construction
[0046] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention is capable of being implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0047] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used here...

Abstract
The invention relates to a dual-color temperature COB light source and a preparation method thereof. The two-color temperature COB light source comprises a base, a bonding pad, a LED chip and a plurality of fluorescent glue layers, the LED chip comprises a first color temperature LED chip and a second color temperature LED chip which are uniformly arranged at intervals in an array, the plurality of fluorescent glue layers are arranged in the first color temperature LED chip, and the second color temperature LED chip and a solid crystal area so that CRI>95 after the first color temperature LEDchip and the second color temperature LED chip independently or commonly emit light. The preparation method of the fluorescent glue layers can prepare a plurality of fluorescence glue with different colors, the color temperatures and the colors can be regulated through the preparation matching of the fluorescent glue, and therefore, the dual-color temperature COB light source and the preparation method thereof are concise in preparation process, flexible in regulation of the color temperature and display, convenient in mass production, is capable of displaying specified photoelectric parameters by controlling the color temperature, can meet different white light demands easily and are low in cost.
Description
technical field [0001] The invention relates to the technical field of LED lighting, in particular to a COB light source with two color temperatures and a manufacturing method. Background technique [0002] As a kind of lighting equipment, LED light source, also known as LED integrated light source, is more and more widely used in the industry. Its working principle is: the positive pad and the negative pad are energized, the LED chip emits light, and the fluorescent layer is excited to realize the LED light source. glow. With the gradual deepening of human understanding of LED light sources, the requirements for CRI color rendering index are gradually increasing, especially in the field of photography lighting and exhibition lighting, the requirement of CRI>95 has become the mainstream. Therefore, the color rendering index of LED light source is very important. [0003] The traditional two-color temperature COB light source currently adopts the following manufacturing ...
