Description

Method and device for simulating flame burning image

The present invention relates to a method and related apparatus for simulating a flame image by an electronic technique for use in electric fireplaces, decorative wall lamps, murals, and partial displays. Background technique

With the development of science and technology and increasing environmental requirements, traditional physical burning fireplaces have gradually been replaced by clean, safe, convenient and hygienic electric fireplaces. Modern home decoration also requires dynamic, vibrant decorative items. In the past, the method of imitating the burning flame was mostly produced by the method of transmission, reflection, diffraction, refraction and projection by a limited light source of ordinary light bulbs. The brightness was not enough, the picture was dull and lacked the various changes that should be experienced when the real flame burned. The degree is not high, the outer casing tends to be heavy, and the motor is noisy.

For example, U.S. Patent No. 4,890,600, which is a device for simulating a flame burning image (Fireplace burning simulator unit, Januaiy 2, 1990), is characterized by a bulb disposed in front of the bottom of the housing, and a reflective brush strip driven by an electric motor behind the bottom of the housing. The front surface of the reflective brush strip is provided with an image forming screen such as a curtain wall glass for scattering light on the back surface, and the light emitted by the bulb passes through the irregular reflection of the reflective brush strip to form a slowly rising flame image on the image forming screen. Image, because the light is formed by the light reflecting the light bulb of the reflective brush, the intensity of the light is not enough, the brightness of the flame is limited, the flame is not red enough, and the flame is patterned, which is not realistic and natural.

For example, the Chinese patent No. ZL01113160.8 simulates a flame burning image device, which uses a flashing light source for direct projection, that is, a dynamic light source is arranged behind the imaging screen such as the curtain wall glass, and the inside of the dynamic light source is a bulb, and the outside of the bulb is an electric motor. A hollow columnar transmissive cover that rotates is rotated, and the translucent cover is covered with a light transmission hole. The light from the bulb is illuminated onto the imaging screen through the aperture of the flame plate, causing the spot on the imaging screen to become a rising flame. Since the light is direct, the intensity of the light is relatively high, and the flame is brighter and has a relatively large progress. However, there is still a problem that the flame pattern is not active enough, and the motor is used to drive the column-type transmissive cover to rotate. Structure, therefore, the volume is relatively large, the thickness is not thin enough, the motor noise is relatively large, and further improvement is needed.

In summary, the above several flame simulation devices have their own shortcomings, but there is a common shortcoming. The flashing light source needs mechanical components to drive or drive, forming a light source to flicker, thus causing flame fluttering effect, so the overall mechanical structure is relatively large, and the thickness is not thin enough. The weight is relatively heavy, especially when the motor is used for a long time, it is easy to generate noise. For the device using the flame orifice plate, since the light source of the light is fixed, the pattern of the flame shape is formed, which appears to be a single board. Lively and vivid, can not meet the consumer's request for appreciation of the flame.

Further, the Chinese patent "Flame Simulation Equipment" with the patent number 200610006411.7 discloses a device comprising: a simulated fuel bed; a screen with a front surface close to the simulated fuel bed and a rear surface at a relative position of the front surface; and a flame film projector for Project a film of flame on the back surface to display a movie of flame on the front surface. The front surface of the screen is partially inverted Shot, in order to give a reflected image of the simulated fuel bed, such that the reflected image appears at least partially behind the flame film displayed on the front surface, which is disadvantageous in that it is bulky, not sufficiently thin, and mechanically noisy. Chinese Patent No. 200610008599.9, which includes a flame simulating assembly for an air filter, includes a housing including a top panel, two or more side panels supporting the top panel, and a rear panel connecting the side panels a panel and one or more front panels disposed substantially relative to the rear panel, and further having a simulated fuel bed, a screen disposed behind the simulated fuel bed, and a flame image for providing a flame image on the screen The assembly, the screen, the outer casing and the simulated fuel bed define an interior chamber, the assembly further comprising one or more exhaust gases arranged to provide flow from the one or more intake apertures through the chamber to allow the air to exit the chamber A fan of the airflow of the aperture and one or more air filters for filtering at least a portion of the air in the air stream. The internal chamber is substantially airtight except for the intake and exhaust ports. The drawback is that there is no optical blurring component between the screen and the flame image sub-assembly. To obtain a more realistic image on the screen, it is necessary to use high-quality flame image electronic components, resulting in cost increase, which is not economical and practical.

At present, almost all of the simulated flames use incandescent lamps as the light source, and incandescent lamps are a backward product with high energy consumption. Many countries are limiting the use of incandescent lamps, so they use high-efficiency LEDs (light-emitting diodes) to simulate Flame burning has broad application prospects.

The brightness of the LED changes. When displayed, the actual color of the flame image is restored by the color of the LED and the complement of the gradient complementary film. This can greatly reduce the chip capacity requirements, reduce circuit costs, and increase the price competitiveness of products.

The flame burning continuous video is cyclically played within a certain length, and the length of the basic unit is generally more than 2 seconds; playing an animation or a picture, the selected picture is between several to several hundred, which can produce an ideal dynamic play. effect. With the advancement of science and technology, the economic chip can store more and more pictures of each flame picture. The more the number of frames, the more the change of flame combustion, the lower the repetition rate. The speed of flame burning can be achieved through different playback speeds.
