Problems solved by technology

However, since the LED light bulb is fixed on a mounting substrate for lighting, the light-emitting range of the LED lighting lamp using this installation method is relatively narrow, and the lighting effect is not ideal; in addition, since the mounting substrate is mostly made of epoxy resin , its heat dissipation effect is poor, causing the LED lamp to work in a high temperature environment for a long time, and the service life is low

Abstract

The invention relates to a light emitting diode (LED) illumination lamp. The LED illumination lamp comprises a metal lamp cap, a heat conducting lamp shell, a driving circuit board, substrates, an LED lamp and a transparent lampshade, wherein one end of the heat conducting lamp shell is fixed in the cavity of the metal lamp cap; the driving circuit board is arranged in the cavity of the heat conducting lamp shell, and the driving circuit board is electrically connected with the metal lamp cap in the heat conducting lamp shell; at least one LED lamp is arranged on the substrates, the LED lamp is electrically connected with the driving circuit board through a lead, and the substrates and the LED lamp are sealed in the transparent lampshade; a fixed board is arranged at the other end of the heat conducting lamp shell, and the fixed board is provided with holes through which leads of the LED lamp and the driving circuit board pass; and the substrates are triangular, the number of the substrates is at least three, the substrates are all arranged on the fixed board, and the whole arranged substrates form a prism. The LED illumination lamp is convenient to process and has wide luminous range and long service life.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lighting bulb. Background technique [0002] LED lamp is a new type of lighting lamp developed and put into production in recent years. Compared with traditional lamps, it has the advantages of low voltage, low power consumption, high luminous efficiency, high reliability and long life. Lighting source. Current LED lighting bulbs, such as figure 1 As shown, the main structure of this LED lighting bulb includes a lamp base 101, a lamp housing 102, and a transparent lamp shade 103. A driving circuit board 104 and a substrate 105 are arranged in the lamp housing 102. A plurality of LED lamps 106 are arranged on the substrate 105. After the power is turned on, multiple LED lights will emit light at the same time, which can achieve a certain brightness and realize the lighting effect. However, since the LED light bulb is fixed on a mounting substrate for lighting, the l...
