Universal type LED (light emitting diode) bulb forming method and LED bulb with fluorescent inner cover

Abstract

The invention discloses a universal type LED (light emitting diode) bulb forming method and an LED bulb with a fluorescent inner cover. The universal type LED bulb forming method comprises the steps as follows: bonding a light machine module onto a metal heat conducting bracket; surrounding the light machine module by an annular nonmetal bracket liner; fixing the bracket liner to the heat conducting bracket; mounting a bulb part by taking the heat conducting bracket and the bracket liner as a center of a bulb structure to form the LED bulb, thereby enabling a structure between the light machine module and the heat conducting bracket to be simple and reliable and facilitating LED heat radiation; packaging an LED chip on the light machine module only by transparent silica gel; and arranging the bulb inner cover with fluorescent powder coated on the inner side at the outer part of the packaged light machine module. The LED bulb, a lamp and an illuminating control product can be independently produced and used, of the links in the production chain of an LED illuminating product are greatly reduced, batch production efficiency is improved, and industrialization of an energy-saving LED illuminating product is facilitated.

Description

technical field [0001] The invention relates to a construction method of a general-purpose LED light bulb and an 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 182.45...

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.
