Description

LED light source of flare lamp

[ technical field ] A method for producing a semiconductor device

The utility model relates to a LED light source field specifically is a flame lamp LED light source that can produce flame and flame effect.

[ background of the invention ]

For example, the LED bulb, the lamp and the lamp decoration with the flame effect in the burning state of the candle can be used as auxiliary lighting and decoration to render the antique atmosphere for the application environment, and can bring brand new visual experience for consumers.

The cylindrical LED flame lamp sold in the market at present has the structural characteristics that a flexible PCB is adopted as a substrate carrier, arranging a plurality of granular LED lamp beads (such as LED lamp beads with the size of 2.8x3.5mm, wherein the distance between the upper part and the lower part of each lamp bead is about 2-5 mm), sticking the flexible PCB substrate fully distributed with the LED lamp beads on the outer wall of a cylindrical tube for fixing to form a cylindrical flame light source with side circumference for emitting light, the progressive brightness change or jumping brightness change between the adjacent LED lamp beads is driven by the driving power supply and the control circuit, the LEDs are projected on the inner side wall of the white light-transmitting plastic lampshade after emitting light, a series of light and shadow lines are projected to change in a shaking way, and the burning-shaped LED light flame is simulated, but this scheme effect is relatively poor, and the observation has dazzling graininess within 4 meters apart from white printing opacity plastic lampshade, because is that the cylinder side is luminous also causes the top to have the dark space. Another improvement scheme on the basis of the scheme at present is that a luminous source is mainly improved, a straight-plate type circuit hard substrate with the thickness of 0.4-1 mm is used as a substrate carrier, LED lamp beads are attached to two wide surfaces of the substrate, the whole light emitting effect is that the two wide surfaces of a strip-shaped thin plate emit light in the direction, the dark area at the top of the lamp body is weakened to a certain extent due to the fact that the luminous volume is reduced, but the two narrow surfaces of the substrate with the thickness of 0.4-1 mm do not emit light, and two obvious dark areas are projected to the side face of a white shell.

Two kinds of above adoption LED flame lamp have adopted LED lamp pearl as the light emitting source, through the optical imaging principle of back light projector, rock the line with the light source and throw on white printing opacity casing, simulation flame combustion effect. The main defects are a series of defects and shortcomings caused by the fact that the flame light source adopts granular LED lamp beads. The visual effect of the dazzling dot matrix light emitted by the LED lamp beads on the flame light source is dazzling, granular, discontinuous, and the dot matrix light flashes in turn, and the light needs to be softened and weakened by the white transparent outer shell, so that the dazzling feeling of the grains is reduced and weakened; if white casing transmittance is high, the granular sensation of lamp pearl is strong, closely sees that the flame effect is poor, if white casing transmittance is low, increases light loss again, has reduced lamp body luminance and intensity again, makes the lamp body receive other light interference easily and leads to the flame effect not obvious, and white cell-shell is not dirty and yielding the look, further reduces luminance and also is not fit for using in the open air and environment that has light interference.

Therefore, the flame LED light source which has the visual effect of burning fire, high brightness, no dark space, overall continuous light emission, adaptability to the transparent shell, strong light interference resistance and strong environmental adaptability is provided, and the problems to be solved in the field are urgently needed.
