DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

As shown inFIG.1toFIG.8, the simulated flame lamp stand100of the present invention includes a simulated flame lamp1, a lamp stand body2and a power supply3, wherein the lamp stand body2has a hollow structure. The simulated flame lamp1is arranged at an upper end of the lamp stand body2, and the dispersion lamp shade11is extended beyond the upper end of the lamp stand body2. The power source3is arranged in the lamp stand body2and electrically connected with the simulated flame lamp1. Specifically, the simulated flame lamp1includes a dispersion lamp shade11, a support12, a first illuminant13, a second illuminant14and a control IC15. The support12is provided with a mounting platform121, and the dispersion lamp shade11which is milky white is arranged outside the mounting platform121. Specifically, the dispersion lamp shade11is a bulb shell, and the diameter of the bulb shell gradually decreases from bottom to top. In such an arrangement, the shape of the simulate flame is more realistically and the simulation effect is improved. The first illuminant13is arranged on the lower side of the mounting platform121and emits light towards the side wall of the dispersion lamp shade11which is located around the lower side of the mounting platform121. The second illuminant14is located above the first illuminant13and arranged on the upper side of the mounting platform121to illuminate the side wall of the dispersion lamp shade11which is located around the upper side of the mounting platform121. The first illuminant13is always on when energized and the light of the first illuminant13is projected to a lower section of the side wall of the dispersion lamp shade11. The control IC15is arranged on the mounting platform121and electrically connected with the second illuminant14, and the control IC15is configured to control the second illuminant14to emit light at intervals so that the light of the second illuminant14is projected to an upper section of the side wall of the dispersion lamp shade11.

Referring toFIGS.3,4,5and7, the first illuminant13is a surface mounted device (SMD) type (SMD-type) LED light emitting chip, which can be affixed to the bottom surface of the lower side of the mounting platform121, or located on the lower side of the mounting platform121and fixed on the support12. The first illuminant13includes a lamp bead. The lamp bead of the first illuminant13is oriented away from a direction of the second illuminant14. The second illuminant-emitting body14is an LED light emitting chip, and the second illuminant-emitting body14includes a lamp bead. The lamp bead of the second illuminant14is oriented away from a direction of the first illuminant. Therefore, by using the SMD-type LED light emitting chip as the first illuminant13, the lamp bead of the first illuminant13is set downward, and the lamp bead of the second illuminant14is set upward, so that the light emitted by the two illuminants can form two layers on the dispersion lamp shade11, but is visually continuous. Thus, when the second illuminant14flickers, the lengths of the light from the illuminant are different so to achieve the flame burning effect of the flame dancing up and down.

Referring toFIGS.3,4, and7, the simulated flame lamp1further includes an epoxy resin package16, which is wrapped outside the mounting platform121to encapsulate the first illuminant13and the second illuminant14. By using an epoxy resin package16to package the mounting platform121, the first illuminant13and the second illuminant14, the four can be relatively fixed and form an integrated structure for easy installation, and the first illuminant13and the second illuminant14can be protected, thereby effectively extending the service life of the flame lamp. The epoxy resin package16is cylindrical and transparent. Alternatively, the upper end face of the epoxy resin package body16is flat or is a concave structure. In the present embodiment, the upper face of the epoxy resin package16has a concave structure161. The concave surface161may be cone, arc or spherical. In such a way, the upper end face of the epoxy resin package16is configured as a concave structure so that the epoxy resin package16forms a concave lens, thereby diffusing the light of the second illuminant14to the surrounding areas, that is, guiding the light to project to the surrounding areas of the upper section of the dispersion lamp shade11, so that the light around the middle and upper sections of the dispersion lamp shade11is more concentrated than the middle and lower sections, and the light color is darker than other areas, which can better simulate the visual effect that the outer flame is darker than the inner flame to obtain the improved simulation effect.

Referring toFIGS.3and4, the support12is provided with a positive electrode support leg122and a negative electrode support leg123, the mounting platform121is arranged between the positive electrode support leg122and the negative electrode support leg123, and the positive electrode support leg122is electrically connected with the positive electrode of the power supply3, the first illuminant13and the positive electrode of the control IC15, respectively. The negative electrode support leg123is electrically connected with the negative electrode of the power supply3, the first illuminant13, and the negative electrode of the control IC15, respectively. By using the support legs of the support12as conductive pins, both support and connection are realized, thereby simplifying the internal structure and improving the convenience of assembly.

In addition, as shown inFIG.4, the upper side of the mounting platform121is provided with a groove121a, the second illuminant14is arranged in the groove121a, and the control IC15is arranged outside the groove121a. The groove121acan be used to hold phosphors to achieve the purpose of adjusting the color of the light. The groove121ain this embodiment has an inverted conical structure. In another embodiment, the mounting platform121can also be provided without the groove121aand the phosphors, and the second illuminant14can achieve the same function only by selecting an LED lamp that can emit colored light.

Combined withFIG.5toFIG.8, in the present invention, the first illuminant13is arranged on the lower side of the mounting platform121. Specifically, the first illuminant13is configured to always emit light when energized, and emit light toward the side wall of the dispersion lamp shade11which is located around the lower side of the mounting platform121, in such a way, a first flame projection is formed around the side wall of the lower section of the dispersion lamp shade11. The second illuminant14is arranged on the upper side of the mounting platform121so that the second illuminant14is located above the first illuminant13, so as to emit light to the side wall of the dispersion lamp shade11which is located around the upper side of the mounting platform121, in such a way, a second flame projection is formed around the side wall of the upper section of the dispersion lamp shade11. Moreover, by controlling IC15to control the flicker of the second illuminant14, the second flame projection appears intermittently, so that when the second flame projection appears, it can form a longer flame effect than the first flame projection, and the length is longer than that when only the first flame projection appears. In such a way, different lengths of the first and second flame projections can result in visual differences, thereby generating the flame burning effect on the dispersion lamp shade11that the flame dances up and down. The first illuminant13and the second illuminant14are respectively arranged on the upper and lower sides of the mounting platform121, thus it just requires two lamp beads to simulate the flame burning effect. Compared with the prior art, the number of lamp beads is effectively reduced. Furthermore, the flame burning effect can be simulated by merely controlling one of the lamp beads to flicker, thus the control is simple to reduce the cost of the entire simulation flame stand100.

The control principle of the control IC15involved in the simulation flame lamp stand100of the present invention is well known to persons ordinary skilled in the field, which will not be explained in detail therefore.

It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. Such modifications and variations that may be apparent to those skilled in the art are intended to be included within the scope of this invention as defined by the accompanying claims.
