Field of the Invention The present invention relates to an illumination system including a susceptor structure, at least one light source, and a housing having a wavelength conversion material. [Prior Art] Recently, there has been a significant advance in increasing the brightness of a light-emitting diode (LED). Therefore, LEDs have become a sufficiently bright and inexpensive light source, for example, as a light source such as a lamp with adjustable color, a direct-view liquid crystal display (LCD), and a light source in rear and rear projection displays. Any number of colors, such as white, can be produced by mixing and controlling the intensity of different color LEDs, such as red, green, and blue LEDs. The color of the light produced is further determined by the type of LED used. One of the disadvantages of using LEDs is that they are relatively narrow bands. Therefore, the combination of several primary colors results in a spectrum with many wavelength peaks. This means that although three LEDs (e.g., red, green, and blue) can be used to make white light, when the object system is illuminated by light, this does not necessarily produce a very natural color. Therefore, it has been proposed to apply a phosphor coating to an LED ' such that the narrow band light emitted by the LED is converted to light having a wider spectral bandwidth. An example of such an embodiment is disclosed in US Pat. No. 6,504,301, which is incorporated herein incorporated herein by reference. Improvement of MR-16 halide cracking. The phosphor member is adapted to receive blue light (approximately 460 nm to 480 nm) emitted by the lEDs and to shift the optical energy up to an intermediate wavelength of approximately 52 〇. The resulting emitter is a wideband light that extends from 480 nm to 62 〇 136241.doc 200946820 nm. However, the LED package disclosed above is not suitable for use in a conventional light bulb', for example, a standard "A" type bulb, or a more complicated bulb shape/form. SUMMARY OF THE INVENTION Therefore, there is a need for a novel illumination system that is suitable for the improvement of conventional or more complex light bulbs, wherein the illumination system is manufactured at a cost suitable for a low cost consumer environment. According to one aspect of the present invention, the above object can be achieved by an illumination system that includes a pedestal structure; at least one light source disposed on the pedestal structure, the at least one light source emitting a first bandwidth a light beam; and a housing having a wavelength converting material, the wavelength converting material being adapted to convert light having the first bandwidth into light having a second bandwidth, the first bandwidth being wider than the first bandwidth Wherein the illumination system further includes an optical member disposed between the at least one light source and the outer casing, the optical member being adapted to modify a shape of the light beam to increase a surface area of the outer casing that receives light emitted by the at least one light source, or Equalize the observed illumination of the enclosure. The optical member, e.g., introduced in the form of an auxiliary optic, allows light emitted by the at least one source to be substantially evenly spread over the entire visible surface area of the housing. The optical member is configured to receive a beam of light emitted by the at least one light source and reshape the beam such that it conforms to the shape of the housing, i.e., substantially all of the surface area of the housing will receive light from the at least one source. Thus, what is required is that the light emitted by the at least one light source is received homogeneously by the wavelength converting material disposed with or integrated with the outer casing. Therefore, one of the advantages of the present invention is that the observer will more naturally feel the resulting illumination system of 136241.doc 200946820, that is, similar to a conventionally illuminated bulb that can be comprised of a glass, plastic, composite The material of the polymer or any other suitable transparent or translucent material is formed. In order to reassemble a general illumination system, such as a light bulb, the housing is preferably configured to have the same form factor as, for example, one of a southern, incandescent, and fluorescent bulb. However, the optical member included in the illumination system allows the housing to be configured according to different complex forms and shapes. That is, the positioning and/or assembly of the optical member is adjusted for the size and shape of the housing. According to a preferred embodiment of the invention, the illumination system comprises a plurality of light sources 'for example, a plurality of blue LEDs, UV LEDs or a plurality of LEDs of different colors » the use of blue LEDs is advantageous because of the advanced The wavelength converting material has a high conversion efficiency when receiving light in the blue bandwidth, for example, having a main light emitter β of about 460 nm to 480 nm. Further, it is also possible to include a plurality of different color LEDs (for example) For example, a combination of a blue LED, a red LED, and a green LED, that is, LEDs having different and separated peak wavelengths. In this case, the inclusion of the red LED and the green LED (or at least one of the red LED or the green LED) allows for a "color enhancement", that is, a bandwidth for filling the included LED, The gap between the visible spectra. The advantages of LEDs include lower power consumption and increased lifetime of the illumination system compared to a conventional bulb. In addition, the LEDs can also be configured to emit violet light. Preferably, the second bandwidth is selected to be between 400 nm and 700 nm. That is, preferably, the illumination system emits light that covers the entire visible spectrum/band, i.e., produces substantially white light. The illuminating system will typically emit light having a mixture of the first bandwidth and the second bandwidth, as taught by the skilled practitioner, I36241.doc 200946820. In another preferred embodiment of the invention, the outer casing (sometimes referred to as a bulb structure) is removably coupled to the base structure. In this embodiment, it is possible to mount different and complex shaped housings to the base structure. This allows the user of the illumination system to change the housing to accommodate different environments, for example, in a high profile design environment, in order to allow the optical member to reshape and redirect the light beam emitted by the source to fit the housing, The optical member is preferably disposed on the at least one light source to become a mirror or collimator for redirecting and collimating. Accordingly, one of the receiving ends of the optical member is preferably configured to coincide with the light source. In still another embodiment of the present invention, the susceptor structure includes control logic for controlling at least one of intensity and color point of light emitted by the at least one light source. The control logic is preferably adapted to receive a signal from the at least one sensor. The sensor is provided for measuring at least the output of the light sources in the different spectral bands, the operating temperature of the light source, and possibly White light also emitted by the illumination system. The control logic then adjusts the intensity of the light source such that the illumination system is perceived to emit light having a continuous intensity. If a different color LED is selected, the control logic can be further adapted to increase or decrease the color enhancement provided by the additional LED. Preferably, the optical component includes at least one of a collimator and a reflector. In one embodiment the optical member comprises a plurality of different collimators and combinations of reflectors. Preferably, the wavelength converting material comprises a phosphor, a scintillator, and at least one of a mixture of phosphorescent and phosphoric. Both the phosphor and the scintillator are materials used to "expand" the bandwidth of the light received by the wavelength converting material. Phosphorescent system A substance that exhibits a phosphorescence phenomenon (sustainable growth after exposure to light or charged particles such as electrons). Similarly, a scintillation system absorbs high energy (ionized) electromagnetic or charged particle radiation, followed by a fluorescent photon that characterizes the Stokes frequency shift (longer) wavelength, releasing the previously absorbed energy. The invention allows for mixtures of different phosphors and/or scintillators. In addition, the wavelength converting material may include a fluorescent material, an organic fluorescent material, an inorganic fluorescent material, a saturated can body, a phosphor particle, a phosphor material, a YAG:Ce phosphor, or the like to convert electromagnetic radiation into illumination. And/or visible light materials. The present invention will now be described in more detail hereinafter with reference to the accompanying drawings in which <RTIgt; However, the present invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. To skilled educators. The same reference symbols are used throughout the text to identify the same elements. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a block diagram of an illumination system, which provides a general description of the inventive concept. The illumination system 100 includes a susceptor structure 1 〇 2 having a plurality of light sources disposed thereto. In the present invention, the light sources are plural, and different types of light sources can be used, for example, different types of solid state light sources known in the art. The illumination system 100 further includes a housing 1〇6 configured to connect to the pedestal structure 102 and substantially surround the leds 104, 136241.doc •11 - 200946820. In general, the base structure 102 includes a heat sink and a control unit for controlling the illumination system. In the present invention, the housing 1〇6 completely surrounds the LEDs 104' thus forming a lighting system 1A that is substantially similar to a regular light bulb. However, the housing can be configured as a cover member that does not completely surround the LEds 104. For example, this configuration is useful if the illumination system 1 根据 according to the present invention is disposed in a corner of a room, wherein the housing 1 〇 4 provides cover on both sides, and the two walls of the corner A cover is provided on the other side. The outer casing may be formed from a material comprising glass, plastic, composite, polymer or any other suitable material. The outer casing 106 preferably has a thin layer of wavelength converting material 108 adapted to receive light having a first peak wavelength and to convert an essential portion of the light to light having a longer second peak wavelength. In accordance with the present invention, the LEDs 104 are adapted to emit light having the first peak wavelength, preferably in a lower region of the visible spectrum. However, it is also possible and possible to use LEDs of different colors (or different light sources) within the scope of the invention. However, currently available wavelength converting materials 108 have a higher slew rate when receiving light in the lower visible wavelength spectrum. When the wavelength converting material 108 receives light emitted by the LEDs 104, the wavelength converting material 1 〇 8 will receive the light, convert a major portion of the light, and emit light having the second ben wavelength. However, some of the light having the first peak wavelength will not be converted and thus allowed to pass through the wavelength converting material 108 such that it mixes with light having the second peak wavelength. The resulting light emitted by the illumination system 100 will thus become a uniform 136241.doc -12·200946820 of light having first and second peak wavelengths. According to the present invention, the light having the first peak wavelength will have a first bandwidth 'and the light having the second peak wavelength will have a second bandwidth 'where the second bandwidth is greater than (wider than) the first A bandwidth. Preferably, the second bandwidth covers most of the visible spectrum, that is, between about 4 nanometers and 700 nanometers, and an observer feels essentially white light. The wavelength converting material 108 is preferably selected from the group consisting of a phosphor, a scintillator, a fluorescent material, an organic fluorescent material, an inorganic fluorescent material, a saturated phosphor, a phosphor particle, a phosphor material, and a YAG:Ce phosphor. At least one or a mixture of the body or other group of materials that convert electromagnetic radiation into illumination and/or visible light. The illumination system 100 includes only an optical member 11 〇 disposed between the 荨LED 104 and the housing 1 〇6. In this embodiment, the optical member 110 includes a predetermined lens system that is adapted to redirect and collimate light emitted by the LEDs 104 such that it is suitable or suitable for the form factor of the housing. In the illustrated embodiment, the outer casing 1 〇 6 slightly extends the waveform factor, similar to an elliptical shape. Accordingly, the optical member 11 is adapted to project more of the received beam provided by the LEDs 104 such that it also reaches the outermost portion of the outer casing 106. By adapting the optical member no in this manner, it is possible to provide an illumination system 110 having an outer casing 1 6 that is substantially uniformly illuminated. That is, all portions of the interior of the outer casing 106 essentially receive the same amount of light from the LEDs 104 after which the wavelength converting material 108 is deposited or integrated into the outer casing 1〇6, converting the light to the essence. White light on it. In order to reassemble a conventional illumination system, such as a light bulb, the housing is preferably configured to have an example of 136241.doc -13· 200946820 'with self-organizing, incandescent and fluorescent bulbs when placed in a luminaire The same form factor. The card-mounted lighting system allows for large shapes to be free. In Figure 1, all of these LEDs 104 have a blue LED having a peak wavelength of about 460 nm to about 480 nm. However, it is also possible to use different types of light sources that emit light having a different peak wavelength. It may also comprise one or more light sources that emit light in a different wavelength range, for example in the orange to red spectrum. This includes providing a color enhancement in the case where the wavelength converting material 108 is not so strong in providing light in the spectral region. To control the illumination system 100, the pedestal structure 102 preferably includes for controlling such Control logic for the intensity of the LEDs 104. The control logic included in the pedestal structure is preferably adapted to receive an information signal from a sensor that is provided for measuring or by the light emitted by the LEDs 104. System 1 〇〇 emitted light. For example, such a sensor can be configured to be close to the LEDs 104 to collect a smaller amount of scattered light. In controlling the LEDs 104, the control logic will receive the information signals from the sensors and adapt the light emitted by the LEDs 104 such that they are maintained at substantially the same level. The sensor can be a light pole or a similar device. The control logic can also be adapted to receive the information signals from a temperature sensor' and control the LEDs 104 based on the same criteria as discussed above. Referring now to Figure 2, there is shown an alternative illumination system 2A in accordance with the present invention similar to Figure 1. The alternative illumination system 200 includes a base structure 202 and a housing 204. In the illustrated embodiment, The outer casing 204 is constructed as a multi-branch configuration of a complex shape of 136241.doc 14-200946820, for example comprising two, three or more branches β. Such a multi-branch configuration is generally applicable to design related implementations, for example In the display and display cabinet environment. A detailed view of an optical member and corresponding blue LED source 206 is also shown in FIG. The optical member includes a collimator 208 and a reflector 210 for redirecting the light beams emitted by the light sources 206. Due to the application of the collimators 208, the shape of the beams will be tuned to be narrower and will be targeted Placing the reflective pupils of the reflectors 210 adjacent to the collimators 208, collecting the light beams from the light sources 206 and redirecting them to the light bulb branches 'ie, the outer casing 204' The inner surface of the bulb branches is effectively illuminated by the blue light. For example, the shape and angle of the reflectors 21 in the form of mirrors achieve an acceptable uniform illumination pattern on the surface of the outer casing 204. The outer casing 204 scatters light (eg, white light) to the outside environment, wherein the outer casing When the 204 is completely covered (inside) by a phosphor layer, the white light is caused by the conversion of light from blue light to white light. In the continued embodiment, each of the three branches of the housing 204 has a corresponding light source 2〇6, a reverse emitter 208, and a collimator 210. In Fig. 2, and then in Fig. 3a and Fig. 3, the pedestal structure 2 〇 2 is configured to resemble a regular E27 pedestal, thus making it an improvement over a regular A or similar bulb. However, different pedestal sizes and bulb shapes are possible and within the scope of the present invention. Similar to Fig. 1, the base structure preferably includes a heat sink and a control unit or the like for controlling the illumination system. Figures 3a and 3b show an alternative to the illumination system 3〇〇 and 3 1〇 according to the invention 136241.doc -15- 200946820 The housing 302 has been configured such that it comprises a
