Description
The utility model relates to decorating uses lampion, specifically is a kind of light emitting diode seven-colour lamp.
At present, known Color-changing lamp adopts incandescent lamp to variegate the glass bulb composition more.It exists, and power consumption is big, brightness is low, the life-span is short, reach the big shortcoming of caloric value.In recent years people are in the Color-changing lamp that constantly explores light emitting diode, are 97226456.6 colored semiconductor variable colored lights as the patent No., and it places three-primary color LED in the bulb, and externally the control of control circuit realizes photochromic any combination down.But it can not realize a lamp seven looks, and by the synthetic seven kinds of fixing photochromic display effects of the principle of three primary colours, volume is not bigger, uses inconvenience under social general at present power mode, is unfavorable for the popularization of product.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of demonstration that can dynamically circulate, static demonstration, the desirable light emitting diode seven-colour lamp of photochromic display effect are provided.
Another purpose of utility model provides use, structure-integrated, the energy-saving LED seven-colour lamp of general family of a kind of suitable society.
The utility model is the innovative product of existing lampion.It comprises lampshade, lamp holder, shell, light emitting diode and control circuit, it is characterized in that: described lampshade is the colour mixture lampshade; Described control circuit is by three primary colours light emitting diode groups, three are respectively applied for the dc constant current power supply that drives described three primary colours light emitting diode groups, with a numerical control device composition that can make the orderly illuminated in combination of described primary colours light emitting diode group, all control circuits place in the shell.
The utility model light emitting diode seven-colour lamp transless, structure and circuit integrating, volume is little, and is in light weight, with low cost, can connect by direct and traditional socket, safe and reliable, is fit to large-scale production.
Its power consumption is few, and the life-span is long, and the illumination of the seven-colour lamp of power consumption 3～4W is equivalent to the illumination with the 25W incandescent lamp of outer glass bulb cover.One lamp, seven looks can change photochromicly automatically in order, and it is luminous also can to select a certain photochromic static state by manual control.Be widely used in fields such as hotel, restaurant, family, hospital, fire prevention, industry, braking control demonstration, building control demonstration, traffic control demonstration.
