General LED (light emitting diode) lamp bulb forming method and hanging lug fixed type LED lamp bulb of fluorescent inner cover

Abstract

The invention discloses a method for forming a general-purpose LED light bulb and a fixed-hanging LED light bulb of a fluorescent inner cover. A silver paste printed circuit is embedded on a heat-conducting bracket with heat sinks formed by sintering non-metallic heat-conducting materials, and then The LED chip or the driver chip is welded on the silver paste printed circuit to form an LED bulb; the inner bulb cover is fixed on the heat conduction bracket by means of a groove, and the LED chip and the driver chip are wrapped in the bulb inner cover; The heat conduction bracket is fixed in the lens bracket with hanging ears, and the lower end of the lens bracket is provided with a lens; the inner side of the bulb inner cover is coated with fluorescent powder, and the LED chip is only encapsulated by transparent silica gel. The light bulb formed by the method of the present invention can work independently, realizes the independent production and use of LED light bulbs, lamps and lighting control products, greatly reduces the production links of LED lighting products, improves the batch production, and is beneficial to LED energy-saving lighting Industrialization of products.

Description

technical field [0001] The invention relates to a construction method of a general-purpose LED light bulb and a hanging ear-fixed LED light bulb of 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 ...

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.
