Light emitting diode lamp bulb

Abstract

The invention relates to a light emitting diode lamp bulb which comprises a lamp shade, a conductive contact, a socket and a light source module; the conductive contact is combined with the lamp shade; the light source module is arranged between the lamp shade and the conductive contact; the light source module comprises a light-transmitting substrate, a circuit layer, an electrode piece, a plurality of light emitting diode chips and a fluorescent layer; the light-transmitting substrate comprises a first surface, a second surface opposite to the first surface, an upper end and a lower end; the circuit layer is pasted on at least one of the first surface and the second surface; the electrode piece is arranged at the lower end of the light-transmitting substrate and is electrically connected with the circuit layer; the electrode piece is inserted in the socket, so as to allow the light-transmitting substrate to stand in the lamp shade; the light emitting diode chips are arranged on at least one of the first surface and the second surface, and are electrically connected with the circuit layer; and the fluorescent layer continuously coats the light emitting diode chips, and extends to the upper end, and a distance is kept between the fluorescent layer and the lower end.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201310118212.5 and the invention name "Light Emitting Diode Light Bulb" filed on April 8, 2013. technical field [0002] The present invention relates to a light-emitting diode bulb, in particular to a light-emitting diode bulb using a light-transmitting substrate to carry light-emitting diode chips. Background technique [0003] Light emitting diode (LED) is a kind of semiconductor component, which mainly converts electrical energy into light energy through semiconductor compounds to achieve luminous effect. Therefore, it has the advantages of long life, high stability and low power consumption. It has been widely used. It is widely used in home, office, outdoor and mobile lighting to replace traditional non-directional light sources such as lamps and incandescent bulbs.

Problems solved by technology

[0005] Since the light emitting diode 226 is a directional light source, the light emitted by the light emitting diode 226 can only go out toward the front (that is, the light emitted by the light emitting diode 226 can only go out in a direction opposite to the direction of the base body 200), so that the light emitting diode The light-emitting area of ​​the light bulb 20 is far less than that of an incandescent light bulb, and it cannot meet the light output requirements of non-directional light sources such as incandescent light bulbs, which causes users to reduce their willingness to use the light-emitting diode light bulb 20
