October 2nd day revised page 5, new description: [New technology field] [0001] [0002] This creation is about a COB (chip on b〇ard) structure of the surface light source, especially A COB surface light source module with high color rendering (c〇1〇r Rendering Index). [Prior Art] The conventionally known LED is a light-emitting element made of a semiconductor material. The element has two electrode terminals, a voltage is applied between the terminals, and a very small current is supplied, and the remaining energy is lighted by the combination of the electron holes. The form stimulates release. In the early years, LEDs were the main application for indicating light sources, and they were used in lighting fields. They only used for indicator lights, or some special applications. In the past two or four years, LED manufacturing costs have continued to decrease, and efficiency and shell size have been increasing. With LEDs with long life, high safety, luminous efficiency (low power), rich colors, high flexibility of drive and regulation, small size, environmental protection, etc., LEDs can be greatly expanded in the general lighting market. Its market demand is growing, and in the field of lighting required for residential lighting, the color temperature of a 60-watt white light bulb is 3,000 K, and the color rendering is close to 1 〇〇; the 21 watt fluorescent light has a color temperature of 3, 〇〇〇 κ The color rendering is about 83; the MR16 specification halogen lamp takes 50 watts as an example, the color temperature is also 3' 000 Κ, and the color rendering is close to 1 〇 (^ Under such conditions, if lED illumination is to replace these three light sources, it is needed LED components also have similar color temperature and color rendering levels, but they can't reduce the luminous efficiency too much. This is a challenge for manufacturers. However, most of the past practice is to add fluorescent powder. Red powder, improve its color rendering, but this way will greatly reduce the luminous efficiency, and the cost of red powder is too high, increasing product manufacturing cost and process stability.
