General LED (light-emitting diode) bulb composition method and liquid fluorescent flange fixing type LED bulb

Abstract

The invention discloses a general LED (light-emitting diode) bulb composition method and a liquid fluorescent flange fixing type LED bulb. According to the general LED bulb composition method and the liquid fluorescent flange fixing type LED bulb, a sliver paste printing circuit is jointly embedded on a heat conductive bracket with a radiating sheet, wherein the heat conductive bracket is formed by sintering nonmetal heat conductive material; an LED chip or a driving chip is welded on the sliver paste printing circuit to form an LED bulb; an internal bulb cover is fixed to the heat conductive bracket in a manner of installing an embedding groove; the LED chip and the driving chip are wrapped into the internal bulb cover; transparent insulating heat conductive liquid can be contained into the internal bulb cover and is internally provided with a fluorescent material; the LED chip is not encapsulated with the gel; and the heat conductive bracket is fixed into an external bulb cover with an installing flange. The bulb formed by the method can be independently operated, so that the LED bulb, the lights and a lighting control product can be independent on production and use; and the production links of an LED lighting product is reduced; the mass production is improved; and advantages are brought to the industrialization of LED energy-saving lighting products.

Description

technical field [0001] The invention relates to a general-purpose LED bulb construction method and a liquid fluorescent flange-fixed LED bulb, 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 182.45LM / W, so there is hu...

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.
