Universal LED bulb formation method and flange fixed LED bulb with fluorescent inner cover

Abstract

The invention discloses a universal LED bulb formation method and a flange fixed LED bulb with a fluorescent inner cover. A silver paste printed circuit is embedded onto a heat conducting support with radiating fins, the heat conducting support is formed by sintering nonmetal heat conducting materials, and then an LED chip or a driving chip and the LED chip are welded on the silver paste printed circuit to form the LED bulb. A bulb inner cover is fixed onto the heat conducting support by the aid of an embedding groove, the LED chip and the driving chip are wrapped in the bulb inner cover, the heat conducting support is fixed into a bulb outer cover with a mounting flange, fluorescent powder is coated on the inner side of the bulb inner cover, and the LED chip is only packaged by transparent silicone. The bulb formed by the method can independently work, the LED bulb, a lamp and a lighting control product can be respectively independent in production and use, production links of LED lighting products are greatly decreased, batch production is improved, and industrialization of the energy-saving LED lighting products is facilitated.

Description

technical field [0001] The invention relates to a method for forming a general-purpose LED light bulb and a flange-fixed LED light bulb with a fluorescent inner cover, belonging to the technical field of LED lighting. Background technique [0002] As a new generation of lighting technology, semiconductor lighting has high photoelectric conversion rate, easy control of light source direction, easy control of lighting period and mode, high color rendering of light source, high power factor under reasonable design, etc., which cannot be compared with other existing lighting technologies. The five energy-saving advantages are favored by global investors and strongly supported by governments of various countries. The luminous efficiency of current LED lighting can exceed 70LM / W, which is more energy-saving than traditional energy-saving lamps. Theoretically, the luminous efficiency of green LEDs can be as high as 683LM / W; the theoretical efficiency of white LEDs can also reach 1...

AI Technical Summary

Problems solved by technology

This has brought a series of fatal problems such as high manufacturing cost, inconvenient use, and difficult maintenance to LED lighting products.

First of all, it is impossible to achieve national and even global unified standardized production in manufacturing, resulting in many product specifications, few batches, and high prices; secondly, the products of each company are various, not universal, let alone interchangeable; thirdly, product failure Sometimes it is necessary to remove the LED optical module, driving power supply, lamps and other overall assemblies for maintenance. Maintenance is extremely inconvenient, and it is very easy to cause fault expansion, maintenance delays, and high maintenance costs.

These defects have greatly restricted the promotion and use of LED lighting, and are flaws in the promotion of LED lighting products.
