For example, incandescent bulbs are inexpensive, but incandescent bulbs have the disadvantages of low luminous efficiency, high power consumption, short life and fragility. The fluorescent lamp is very energy-saving, but the waste of the fluorescent lamp is polluted, fragile, and has a short life. - Relatively speaking, LEDs, cold light sources and other products that meet the national energy conservation and environmental protection safety standards have a comparative advantage. Their characteristics and advantages are: long life, low power consumption, pure light color, high shock resistance. It is safe and not fragile, φ is non-polluting, and can be packaged in a small size. Although it has the above various advantages, it is still limited by the luminous efficiency of the light source such as the LED, the cold light source, and the directionality of the brightness. In order to be fully applied in human life, please refer to the conventional example of the figure. The structure of the conventional LED chip is shown in the figure. The problem of the product as a light source is: First, products appear on the market. A plurality of light-emitting source wafers 11 are mounted on a circuit board 1 , and a conductive layer 12 , M330570 is disposed on the circuit board 10 , and each of the light-emitting source wafers 11 emits light in different directions and angles, because the light-emitting source wafer 11 faces the circuit. The light emitted from the direction of the substrate 10 has no effect. Therefore, the conventional LED and the cold light source may have a low luminosity. The problem of the effective ratio of light rays, although this design can still combine illumination luminosity like traditional light bulbs, but energy waste is a problem that cannot be ignored; therefore, the global light source equipment manufacturers and research units are constantly actively researching and striving Look for designs that take full advantage of all the light energy of the light source. • Second, the conventional circuit board 10 uses a resin coating 13 to position and protect the illuminating light source wafer 11 and refract light by a lens 14, and the surface of the circuit substrate 10 is free of grooves or coatings to limit the barrier resin. In the case of coating, the layout of the resin-coated 3 is not easily controlled, and the groove or cladding step also consumes cost. In order to effectively solve the aforementioned related issues, the creator of this new model developed the design and experiment based on the Φ to develop the technology and experience of related light source lighting equipment and illuminating light source system, and finally developed a new high illuminating light under the goal of improving the above problems. The source of the light source package structure. [New content] The primary purpose of the novel is to provide a high-luminosity light source package structure, which can fully utilize the light of the light source; to achieve the above object, the present invention produces a light on the surface of the circuit board corresponding to the light source of the M330570. a refractive layer, and a plurality of refraction-convex portions are disposed on a peripheral side of the illuminating light source, and the ray refraction layer not only refracts the invalid light of the illuminating light source into effective light, and particularly, the refracting convex portion can fully refract the horizontal direction of the illuminating light source. Light, thereby, the novel structure can fully utilize the angles of light emitted by the illuminating light source, and the refracting convex portion can fully refract the illuminating light source in the horizontal direction without the effective light, which is indeed a high illuminance Light source package structure. The second object of the present invention is to provide a light source package structure with high illuminance, which utilizes high-refraction fill light of horizontal light of the illuminating light source to reduce the number of illuminating light sources. To achieve the above object, the present invention is particularly applicable to the peripheral side of the illuminating light source and A refracting convex portion is disposed between each of the illuminating light sources, and the refracting convex portion can fully refract the ineffective light in the horizontal direction of the illuminating light source, not only can fully fill the light, but also can make the refracting 0 convex portion play the average illuminance and utilize the advantage of the invalid light. The number of illuminating light sources installed can be reduced in products with a certain luminosity requirement. The plurality of refracting convex portions disposed on the circumferential side of the illuminating light source may be made by metal sputtering, electroplating or surface deposition technology, and the refracting convex portion may be synchronously formed with the same material as the light refracting layer; The forming position can be performed on the circumference of any one of the illuminating light sources or between the two illuminating light sources, and the effect of refracting the horizontal direction of the M330570 ray can be exhibited; and the shape of the refracting convex portion can be a semicircular type or a cone commonly used for general refraction design. Designs such as type, block type, and water drop type can all be used to reflect the refraction changes under various requirements. It should be noted that the light-refractive layer of the circuit board of the present invention can also be made by metal sputtering, electroplating or surface deposition technology, so that it has a smooth metal mirror surface, and the light-reflecting layer corresponding light source can be used as a guide. The light bevel or the light guiding arc surface enhances the luminous rate of the novel.

The light emitted from the illuminating light source 40 toward the refracting layer 30 is reflected by the metal mirror surface 31 of the light refracting layer 30 and cooperates with the light guiding slope 33 of the concentrating portion 32. Refraction of the horizontal light to the outer side of the periphery; therefore, the creation can effectively refract light in all directions of the illuminating light source 40, and exert a better luminosity than the conventional ruling; the key is that since any two illuminating light sources 40 have a refractive convex portion A, and the refractive convex portion A is the same material as the light-refractive layer 3〇 (the same 'with a metal mirror surface'), so the refractive protrusion of the present creation A can effectively refract horizontal light rays between any two illuminating light sources 4 利用 by using the embossed semicircular shape, and generate a moonlight phenomenon similar to the moonlight reflecting solar rays, so that the original illuminating light source 4 is on the circuit board 20 of the present invention.

In particular, each of the refracting convex portions A can exert a illuminating effect, so that the original circuit board 20 has a plurality of refractions in addition to the original illuminating light source 4 .. The convex portion A emits light outward; not only effectively increases the light uniform fill light, And the same M330570 area, the same luminosity requirements of the product can reduce the number of illuminating light sources 40, achieving a significant cost reduction. Here, the functional features of the improved structure are re-summarized as follows: 1.
