Large-angle light emitting diode (LED) bulb lamp

Abstract

A large-angle light emitting diode (LED) bulb lamp comprises a lamp holder, an upper substrate, an upper LED light source arranged on a top surface of the upper substrate, a lower substrate, a plurality of lower LED light sources arranged on a top surface of the lower substrate, and a bulb shell. The lower substrate is arranged on the lamp holder. The bulb shell is covered on the top of the lamp holder. The LED bulb lamp also comprises a fixing column and a reflector element. The upper substrate is fixed above the lower substrate through the fixing column, is held in the bulb shell, and forms a gap with an inner wall of the bulb shell. The reflector element comprises an upper reflection shield. The upper reflection shield is arranged under the upper substrate, is arranged at an interval with the lower substrate, and includes an upper reflection surface for reflecting light emitted from the lower LED light sources on the top surface of the lower substrate towards the direction of the lamp holder. The reflector element also comprises a lower reflection shield which is arranged between the upper reflection shield and the lower reflection shield. The lower reflection shield is opposite to the upper reflection surface of the upper reflection shield. The large-angle LED bulb lamp has advantages of simple structure and easy fabrication.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a large-angle LED bulb lamp. Background technique [0002] With the maturity of LED lighting technology, LED as a light source is more and more used in indoor and outdoor lighting. The light distribution angle of traditional LED bulbs is generally less than 180 degrees. Due to the solid light-emitting characteristics of LED light sources, it is difficult to emit light at large angles. In order to increase the luminous angle, people try to arrange the light source on a fixed column. For example, it was announced on June 9, 2009 that the Chinese Utility Model Patent Application No. 200920205714.0 discloses an LED lighting lamp, which includes a lampshade and a base connected to the lampshade, and the cavity formed between the lampshade and the base The body is provided with a fixed seat, and several LEDs are arranged on the fixed seat, and the fixed seat is formed by splicing several obliquely arra...

AI Technical Summary

Problems solved by technology

[0003] Although this method can increase the luminous angle, it needs to set up a fixed base spliced ​​by multiple inclined mounting plates, and some LED light sources need to be installed obliquely.

This makes the assembly of the fixing seat of the lighting LED lamp more complicated, the installation of the LED light source is more complicated, and the difficulty of mass production is higher.
