Abstract

The invention discloses a ball bulb lamp which comprises a lamp housing, a lamp cover covering the lamp housing, a base plate and an LED (light-emitting diode) chip arranged on the base plate, wherein the lower part of the lamp cover is positioned on the side wall of the lamp housing, a contact point where the lower part of the lamp cover is in contact with the side wall of the lamp housing is lower than the highest point of the side wall of the lamp housing, and a light reflection layer is arranged on the side wall between the contact point and the highest point and is made of a light reflection material; the thickness of the lamp cover is gradually reduced from the center to the edge of the outer side; and an arc-shaped surface with the center protruding relative to the outer edge of the arc-shaped surface is arranged at the upper part of the lamp housing, and the base plate is attached on the arc-shaped surface of the lamp housing.

Description

technical field [0001] The invention relates to a bulb lamp. Background technique [0002] (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of an LED is a semiconductor wafer. [0003] Due to the packaging of the light source, the light-emitting angle of an ordinary packaged LED chip is generally about 120 degrees. In the prior art, in order to expand the luminous angle of the LED bulb lamp, the following methods are usually adopted: [0004] A boss protruding relative to the body of the substrate is formed or arranged on the substrate, and LED light sources are arranged on each surface of the boss, especially on the side wall. However, due to the complex structure, it is not easy to produce and process in large quantities; [0005] A lens is arranged in the LED bulb lamp, although the luminous angle is increased to a certain extent, but the cost of the lens will be increased...
