360-degree led light-emitting flame lamp assembly

Description

FIELD OF THE INVENTION [0001] The present invention relates to a lamp assembly with a flame emitted in the 360-degree range by an LED light according to claim 1, which can simulate a flame tremor effect.

BACKGROUND OF THE INVENTION [0002] With the development of technology, LEDs are gaining more and more application. Squares, gardens and the like can be enlivened by the colorful lights emitted by various spotlights, including LED street lamps, garden lights, etc. Different shades of colors can provide different rendering effects for the surrounding environment. [0003] In addition to lighting effects, some lamps also have decorative effects. In many different forms of lamps, there is a kind of flame lamp assembly that is able to simulate the jumping and flickering of burning flames. The traditional flame lamp assembly uses a glowing quartz bulb and a red silk ribbon that is blown by a fan. The bulb shines on a red silk ribbon, giving the lamp the appearance of a burning flame. However, due to the presence of a fan, noise is inevitable and energy consumption increases. These lamps are restricted for internal use and are not environmentally friendly.

[0004] Document US 5 379 200 A issued to Echard provides a portable device in the form of an electric lantern. The portable lantern device includes a base assembly that includes a housing portion, a lamp support portion supported by the housing portion, and a light diffuser support portion supported by the lamp support portion. The lamp assembly is supported by the lamp support portion of the base assembly. The lamp assembly uses a lamp that includes a bulbous lower part and a pointed upper part so that the lamp resembles a flame. The lighting modulation assembly is located in the electrical circuit between the lamp and the power source. The lighting modulation assembly includes both a circuit chopper for causing lamp light to flicker in flame simulation and a dimmer assembly for dimming the lighting provided by the lamp. As a result, the prior art disclosed in US005379200A is suitable for simulating a very small flame because it only uses a lamp. In addition, in the case of Echard, due to the flame simulation that is carried out by lighting the lamp to flicker, the shape of the flame is limited due to the type of flickering.

[0005] CN 101 603 661 A issued to Lan provides a flame lamp assembly with a switching mode. The flame lamp assembly with switching mode includes a lamp head, a lower housing and LED boards; the circuit board is located in the bottom housing. LED boards contain many LEDs. The printed circuit board contains the PCB, properly assembled serial interfaces, CPU of the intelligent control system and memory. The flame lamp further includes an LED controller and a programmable switch for switching between flame mode and lighting mode; one end of the data cable is connected to the serial interface and the other end is assembled with a programmable switch; programs for flame mode and lighting mode are stored in memory; programmable switch, LED boards and memory are properly connected to the CPU of the intelligent control system. Switching between flame mode and lighting mode can be done for the lamp with flame mode. Lan simulates a flame using LED boards, but Lan needs to send serial time data from memory to LED boards using the SPI serial communication mode and convert the serial data into a parallel signal to power each of these LEDs, which has the disadvantage of a complex process. On the other hand, many shift registers are needed to convert serial time data to parallel signals in Lan, which makes flame simulation expensive. Document EP 2799758 A1 discloses another known LED lamp emitting almost omnidirectional light.
