Definitions

• This invention is applied in the technical field of light bulbs and in the lighting of rooms and relates to a LED light bulb with an integrated system that allows passing easily from a lighter shade of light, to an average and, finally, to a more warm one.
• the current state of the art therefore, provides only a two-tier system, applied to the bulb and to the switches which, if operated repeatedly, are able to change the light of the bulbs and switch from one shade to another.
• SUBSTITUTE SHEETS (RULE 26) aims to solve definitively.
• the wide range of LED bulbs on the market and the technical limitation of them in reproducing a single tone of light (warm-natural-white) imposes to choose the bulb with the light tone that best suits to your needs, at the moment of the purchase; besides if you want to switch to a different tone from the one chosen at the time of purchase, you will have to buy a new bulb with a different tone of light.
• Such a vast choice and diversity of products on the market means that retailers need to stock a number (n) of LED bulbs with a warm tone, a number (n) of LED bulbs with natural tone, and number (n) of LED bulbs with a white tone.
• the goal of the present invention is to allow buying a single product with a light tone to be changed as desired, avoiding the need of buying three different products (bulb with warm, medium and cold light), and resorting to too expensive and / or difficult technologies to access and manage.
• the present invention applies a technology which is integrated directly to the bulb, which allows to choose the tone of light , simply by moving the integrated lever on the desired and clearly indicated tone of light, so that you don’t need to install a suitable switch and without
• the invention consists of a LED light bulb (1 ) which can be installed like normal light bulbs, with a multitone control unit (3E) inside; it is operated by the lever (3F) placed on the base (3) and directly connected to the color temperature change switch (3E4), and can reproduce three shades of light (warm, natural, white);
• the special characteristics of the invention allow choosing the desired tone of light directly from the bulb (1 ) leaving it unchanged and modifying it as desired, simply by placing the lever (3F) on the containing base (3), on the desired light shade - 3200K, 4000K, and 6500K - indicated on the containing base (3).
• you will only need to install the bulb in a common lamp holder (of any kind and attack) and operate the switch to a normal on / off way, to electrify the bulb;
• the light bulb (1 ) will choose the desired light tone directly according to the integrated lever (3F) position on the base (3).
• the selected light tone will be the same until you decide to get another light tone by moving the lever (3F) to a new desired tone.
• Figure 1 and Figure 2 show the device according to the invention (1 ) in a perspective view of all its components
• Figure 3 illustrates the device according to the invention (1 ) in a side view
• the device according to the invention generally indicated with the reference number (1 ), has a cover with standard satin finish (2) and a bulb
• SUBSTITUTE SHEETS (RULE 26) holder base (4) (any various kinds and fitting), both fixed with gluing material (adhesives, silicone or other) to the containing base (3).
• the containing base (3) houses an aluminum led board (3A) (of various kinds and shapes), on which 3200K (3A1 ) and a 6500K led chip (3A2) agree; the chips number vary according to the characteristics of the Ibulb, and placed on a heat sink (3B), all connected to the multi-tone control unit (3E) with a clamp (3C) and 3 output cables (3D).
• the multi-tone control unit (3E) is composed of a capacitor (3E5), an inductor (3E6), a resistor (3E7), and a color temperature change switch (3E4), an electrolytic capacitor (3E3), a transformer (3E2) and input cables (3E8).
• Figure 4 illustrates the operating principle of the tris multi-tone LED bulb (1 ) with an integrated lever (3F) and the multi-tone control unit (3E):
• both the 3200K (3A1 ) and 6500K (3A2) led chips on the aluminum board (3A) light up simultaneously at a 50% intensity and, using the principles of the additive color theory, the light tone emitted
• SUBSTITUTE SHEETS (RULE 26) through the standard satin finish cover (2) stands at an intermediate tone and becomes 4000K , thanks to a mix of the 2-color tones.
• the device according to the invention (1 ) unique, capable of generating a 4000K light tone without having 4000K LED chips installed inside.
• This result is achieved through a combination of tones - 3200K and 6500K - and thanks to the multi-tone control unit (3E), that, specifically designed, transmits the electric impulse to both the 3200K (3A1 ) and 6500K (3A2) led chips; they light up simultaneously, each with a 50% intensity through the cover (2), generating a 4000K light tone.
