Abstract:
The present invention relates to an improvement in the structure of luminous umbrella, using integrated illumination components. The components are ideal for luminous umbrella particularly designed to be used in the evening when visibility is poor, and can be used for other decoration purposes. The integrated illumination components of the present invention are constructed by combining illumination emitter of LED with bases of parts of umbrella, such as linkage members on slip ring, rib members on fixed collar and umbrella handle. When the illumination emitter of LED is mounted on the surface of these parts, the overall umbrella structure can be made smaller and lighter, and the flexibility of light source design can also be maximized. In particular, when base parts with high heat dissipation capability are used as the heat dissipating fins, the full performance of high-brightness illumination emitter of LED can be achieved. The integrated illumination components offer another advantage. With the flexibility of design in the number of illumination emitter of LED and the angle of light projection, the components allow light to be fully projected onto the semi-transparent canopy, which turns luminous umbrella into a lantern with both illumination and warning functions when used at night. Umbrella users thus become obvious objects when walking at night. If color illumination emitter of LED is used, dazzling colored lighting design can be created to the satisfaction of both designers and users, achieving the decorative and aesthetic effect.

Description:
FIELD OF THE INVENTION 
     The present invention relates to the integrated illumination components, which are used to replace traditional umbrella parts to improve the umbrella structure. Integrated illumination components are constructed by combining illumination emitter of LED with bases of parts of umbrella, such as linkage members on slip ring, rib members on fixed collar and umbrella handle. When the illumination emitter of LED is mounted on the surface of these parts, the overall umbrella structure can be made smaller and lighter, and the flexibility of light source design can also be maximized. Application of the present invention turns luminous umbrella into a lantern with both illumination and warning functions, allowing umbrella users to become obvious objects when walking at rainy night and to see roads ahead. 
     BACKGROUND OF THE INVENTION 
     Luminous umbrella refers to an umbrella equipped with illumination component. Such type of umbrella has long been used to improve users&#39; safety in the evening, particularly at rainy nights when pedestrians are unable to clearly see holes on the roads and card rivers are more likely to en danger pedestrians&#39; safety due to poor visibility. The problems can be largely solved when illumination and warning functions are added. As a result, hundreds of related patents issued since 1930 have aimed to offer various solutions to achieve the goal. References cited for the present invention are as follows. 
     Reference One, GB339082A1 “Improvements in or relating to Umbrella, or Walking Stick, and the like” (issued in the UK, 1930), discloses an umbrella in which a light bulb and batteries are installed in the handle to offer illumination and increase user&#39;s safety. The light bulb fitted in the handle is used to illuminate the ground and area ahead. 
     Reference Two, JP2215404A (issued in Japan, 1990), discloses an umbrella in which an LED device is fitted on the top column with batteries being installed on top of the umbrella pole under the canopy as well as in the handle. The LED device is illuminated when the umbrella is opened, so as to make the user more visible to car drivers when walking at night. 
     Reference Three, JP305 7403A (issued in Japan, 1991), discloses an umbrella in which a light-emitting source is added to the top column with a revolving illumination device being installed in the lower part of the handle and the batteries being installed in the handle. The LED light at the top of the umbrella is illuminated for the safety of pedestrians when the umbrella is opened, so as to make the user more visible to card rivers when walking at night. The safety of pedestrians can be further improved with the revolving illumination device fitted in the lower part of the handle, which illuminates the ground and area ahead. 
     Reference Four, CN2217326Y (issued in China, 1996), also discloses an umbrella in which illumination devices are fitted on the top column and in the handle. 
     Reference Five, U.S. Pat. No. 6,068,006A1 (issued in the US, 2000), discloses an umbrella in which a light source unit is installed on the side of the top of the shaft, allowing the light to be fully projected unto the inner canopy. The light is then reflected downwardly to illuminate the surrounding area of the user, also serving as a warning sign to increase the safety of users. 
     Reference Six, DE 10017274A 1(issued in Germany, 2000), discloses an umbrella in which an LED device equipped with batteries and switch is attached to the top column with screw threads. For the safety of pedestrians at night, the LED light is illuminated when the umbrella is opened. The umbrella can also be used as a flashlight to illuminate the road ahead for the user when it is closed, further increasing user&#39; safety. 
     Reference Seven, TW-M256706 (issued in Taiwan, 2005), discloses an umbrella in which a slot seat is attached to the slip ring. The slip ring and slot seat are integrated into one unit, in which multiple parallel LED illumination components are installed. The unit is also fitted with batteries and power switch for users to switch on or off the LED light. 
     Reference Eight, CN2927780Y (issued in China, 2007), discloses an umbrella in which batteries and LED light are installed in the curved handle to offer warning and illumination functions. The LED light installed in the curved handle illuminates the ground and area ahead. With transparent cover, light is projected to achieve the illumination and warning functions. 
     Reference Nine, US2007/0047222A1 (issued in the US, 2007), discloses an umbrella in which an LED device is attached to the top column with batteries and power switch being installed inside the shaft at the position close to the upper part of shaft beneath the canopy. User can switch on or off the LED light when the umbrella is opened and used at night. 
     In all the references cited, the light sources used range from traditional light bulbs to modern LED lights, and the posit ions for installation include top column, the upper part of shaft and handle. The design of using completely packaged LED light significantly improves the illumination effect, increasing the safety of users at night. Most of these solutions focus on structure improvement, either modifying the original structures to accommodate the additional light sources or directly attaching illumination devices to the umbrellas. Nevertheless, most of the solutions do not adopt the high-brightness LED lights and the required heat dissipation devices, suggesting that the weights of umbrellas and complexity of component arrangements increase and that the illumination effect fails to truly meet the users&#39; need. Also, the life of LED light is shortened. All these issues make the umbrellas inconvenient and impractical to use. The problems of currently known technologies are as follows: 
     Changing original structure design to accommodate additional light sources or attaching illumination devices to the umbrellas lead to increase the weights of umbrellas as well as the complexity of component arrangements. 
     Design flexibility is limited if completely packaged LED components are used for additional or attached light sources. As the structure, brightness and dimension are predetermined, the light effect may not be able to fully meet the users&#39; need. The design for heat dissipation is also unable to be taken into consideration. Moreover, layout of the required lead wires becomes another factor affecting the design of space. 
     Using completely packaged LED components makes the method of improving illumination effect with high-brightness LED light infeasible, as the heat dissipation substrate used for the light-emitting semiconductor parts is packaged at the same time with only leads or electric contacts being exposed. Strong heat dissipation capability is required if high-brightness LED light source is to be used. High temperature leads to decline in the light transmission rate of the LED components, the illumination efficiency and the length of service life. Ultimately, the overall brightness is not sufficient enough to meet the users&#39; need. 
     SUMMARY OF THE INVENTION 
     The present invention aims to improve the problems found in the above-mentioned solutions, which adopt additional or attached light sources, and proposes a solution of using integrated illumination components. The solution proposed is to combine illumination emitter of LED with other umbrella parts. The heat dissipation substrate used for the illumination emitter of LED is exposed and not packaged; it is also firmly mounted on the surface of heat dissipation base of umbrella parts. All the electric components used for the present invention meet the necessary electric insulation and safety requirements. Umbrella parts to be integrated include linkage members on slip ring, rib members on fixed collar and umbrella handle. When the illumination emitter of LED is mounted on the surface of these parts, the overall umbrella structure can be made smaller and lighter, and the flexibility of light source design can also be maximized. In particular, when umbrella parts with high heat dissipation capability are used as the heat dissipating fins, the need of heat dissipation required by high-b rightness illumination emitter of LED can be fulfilled. Service life of the illumination emitter of LED can also be significantly prolonged. Moreover, the partly packaged illumination emitter of LED not only becomes smaller in size, but also allows designers to meet various illumination needs, including the degree of brightness and choice of colors, through multiple settings and allocation plans. The flexibility in light design allows light to be completely projected to the inner canopy and to be evenly radiated through the semi-transparent canopy, which turns umbrella into a lantern with both illumination and warning functions when used at night. Umbrella users also become obvious objects when walking at night. In addition, flexible packaging method used for illumination components allows designers to create dazzling effect of colored lighting as well as to achieve the decorative and aesthetic effect with the light projected to the semi-transparent canopy.

At this time, the wire contact on the linkage members on slip ring assembly  2  comes into contact with that on the rib members on fixed collar assembly  3 , constituting a set of circuit switch. When the pressing switch  12  is in a “closed” state, the circuit is activated and the LED illumination device will light up. The inner side of the flexible canopy  10  will be illuminated by the illumination emitter of LED fitted on the linkage members on slip ring assembly  2  and that on the rib members on fixed collar assembly  3 . The umbrella handle illumination assembly  9  will illuminate the roads ahead for the users. If the umbrella is to be used in a fixed location and for a long period of time, external power source, instead of batteries, can be adopted. 
       FIG. 2  illustrates the structure of the illumination emitter of LED used in the present invention. The illumination emitter of LED  4  comprises the LED substrate  44 , transparent package of illumination semiconductor  41 , positive/negative wire contact  42  and wire contact  43 . The bottom surface of LED substrate  441  is attached to the surface of the base of umbrella parts. All the electric components used in the device meet the necessary electric insulation and safety requirements. 
       FIG. 3  illustrates the circuit diagram of the first embodiment. The diagram presents the required electric circuit for installing the illumination emitter of LED  4 . All the electric components referred to in the diagram meet the necessary electric insulation and safety requirements. The two-core electric wire  13  is composed of electric wire  131  and electric wire  132  and is used to form a circuit for connection with pressing switch  12 , battery  15 , the linkage members on slip ring assembly  2  and the rib members on fixed collar assembly  3 . It is also used for connection with the branch parallel circuit of electric wire  13 , formed by linking electric wire  133  and electric wire  134 , for the umbrella handle illumination assembly  9  on the handle  14 .

Electric wire on fixed collar  302  is an independent wire, of which one end point is power wire contact on fixed collar  342 , connecting to electric wire  132 , and the other end point is electric contact on fixed collar  32 . 
     When the umbrella is closed, linkage members on slip ring assembly  2  is moved downwardly to the upper part of handle  14  and separated from rib members on fixed collar assembly  3 , creating an open circuit. At this time, all the LED illumination components are not charged and do not light up. When the umbrella is opened, linkage members on slip ring assembly  2  is moved up to be fixed on the plate spring  111  on the shaft  11 , making electric contact on fixed collar  33  and electric contact on fixed collar  32  to join together with electric contact on slip ring  23  and electric contact on slip ring  22 , respectively, thus forming a complete circuit. When the pressing switch  12  is in a “closed” state, all the LED illumination components will be charged and light up.

The linkage members on slip ring assembly  2  and rib members on fixed collar assembly  3  are embodiments of the integrated illumination components of the present invention. The bases of the linkage members on slip ring assembly  2  and rib members on fixed collar assembly  3  are made of materials with high heat dissipation capability. 
     There are multiple slots on out surface of slip ring  26  of the linkage members on slip ring assembly  2 . Fixed pins of linkages  181  are used to fix linkages  18 . LED assembly on slip ring  21  is fitted on top circumferential surface of slip ring  264  and can be further divided into LED assembly on slip ring  211  and LED assembly on slip ring  212 , connecting to electric contact on slip ring  22  and electric contact on slip ring  23 , respectively. LED assembly on slip ring  21  is assembled in advance or is directly assembled on the base with transparent package of LED assembly on slip ring  25  being completed subsequently with transparent materials.

LED assembly on fixed collar  31  is assembled in advance or is directly assembled on the base with transparent package of LED assembly on fixed collar  35  being completed subsequently with transparent materials. LED assembly on fixed collar  31  connects with electric wire  131  and electric wire  132  at power wire contact on fixed collar  341  and power wire contact on fixed collar  342 , respectively.

With the rib members on fixed collar assembly  3  having good thermal conductivity and the out surface of fixed collar  36  as well as the slots offering heat dissipation function, the heat of LED assembly on fixed collar  31  can be transmitted via these surfaces, thus lowering the temperature of transparent package of illumination semiconductor  41 . 
     The distal end of shaft  11  is sealed with top column  16 . Flexible canopy  10  is fixed with the rib members on fixed collar assembly  3  and is closely connected to top column  16  with fixed cover of flexible canopy  101  to prevent the rain from infiltrating into the inner section of umbrella.

The middle circumferential surface of slip ring  263  is with good heat dissipation capability and the slots offer the same heat dissipation function as heat dissipating fins do. The bottom circumferential surface of slip ring  262  and holding surface of slip ring  265  can be used for heat dissipation as well. The heat of LED assembly on slip ring  21  can be transmitted via these surfaces, thus lowering the temperature of transparent package of illumination semiconductor  41 . The illumination components of LED assembly on slip ring  211  and LED assembly on slip ring  212  are placed on annular surface, so the light is able to illuminate every corner of inner canopy. The number of illumination components and the angle of projection can also be adjusted according to different demands.

When the umbrella is closed, the plate spring  113  is loosened and the switch assembly of slip ring  69  slides down, creating an open circuit. 
       FIG. 11(   a ) illustrates the circuit diagram used in the second embodiment of the present invention. The diagram shows the relations among the illumination components and umbrella parts.

       FIG. 20  illustrates the circuit diagram used in the fourth embodiment of the present invention. The diagram presents the required electric circuit for installing the illumination emitter of LED  4 . All the electric components referred to in the diagram meet the necessary electric insulation and safety requirements. The two-core electric wire  13  is composed of electric wire  131  and electric wire  132  and is used to form a circuit for connection with battery  15 , linkage members on slip ring assembly  2  and rib members on fixed collar assembly  3 . 
     LED assembly on slip ring  21  is composed of LED assembly on slip ring  211  and LED assembly on slip ring  212 , all of which are linked with wire on slip ring  201 , wire on slip ring  202  and wire on slip ring  203 . LED assembly on slip ring  211  and LED assembly on slip ring  212  are created with parallel circuit connecting to the illumination emitter of LED  4 . The end point of wire on slip ring  202  is electric contact on slip ring  22 , and the end point of wire on slip ring  201  is electric contact on slip ring  23 . The two contacts are used to connect with electric contact on fixed collar  32  and electric contact on fixed collar  33 , respectively, to form a circuit. 
     LED assembly on fixed collar  31  is composed of electric wire on fixed collar  301 , electric wire on fixed collar  303  and the illumination emitter of LED with the former two connecting to the illumination emitter of LED in respective parallel circuits. The end point of electric wire on fixed collar  303  is electric contact on fixed collar  33 . The end point of electric wire on fixed collar  301  is power wire contact on fixed collar  341 , which connects to electric wire  131 . Electric wire on fixed collar  302  is an independent wire, of which one end point is power wire contact on fixed collar  342 , connecting to electric wire  132 , and the other end point is electric contact on fixed collar  32 . 
     When the umbrella is closed, linkage members on slip ring assembly  2  is moved downwardly to the upper part of handle  14  and separated from rib members on fixed collar assembly  3 , creating an open circuit. At this time, all the LED illumination components are not charged and do not light up. 
     When the umbrella is opened, linkage members on slip ring assembly  2  is moved up to be fixed in the open position of plate spring  1121  of plate spring  112  on the shaft  11 , creating a gap between electric contact on fixed collar  33  and electric contact on slip ring  23  as well as between electric contact on fixed collar  32  and electric contact on slip ring  22 , respectively. The circuit remains open. All the LED illumination components are not charged and do not light up. 
     When the umbrella is opened, linkage members on slip ring assembly  2  is moved up to be fixed in the close position of plate spring  1122  of plate spring  112  on the shaft  11 , ma king electric contact on fixed collar  33  and electric contact on fixed collar  32  to join together with electric contact on slip ring  23  and electric contact on slip ring  22 , respectively, thus forming a closed circuit. All the LED illumination components will be charged and light up. 
       FIG. 21(   a ) and  FIG. 21(   b ) illustrate the detailed structure of the illumination device used in the fourth embodiment of the present invention. The linkage members on slip ring assembly  2  and rib members on fixed collar assembly  3  are embodiments of the integrated illumination components of the present invention. The bases of the linkage members on slip ring assembly  2  and rib members on fixed collar assembly  3  are made of materials with high heat dissipation capability. 
     There are multiple slots on out surface of slip ring  26  of the linkage members on slip ring assembly  2 . Fixed pins of linkages  181  are used to fix linkages  18 . LED assembly on slip ring  21  is fitted on top circumferential surface of slip ring  264  (n of shown) and can be further divided into LED assembly on slip ring  211  and LED assembly on slip ring  212 , connecting to electric contact on slip ring  22  and electric contact on slip ring  23 , respectively. LED assembly on slip ring  21  is assembled in advance or is directly assembled on the base with transparent package of LED assembly on slip ring  25  being completed subsequently with transparent materials. The heat of LED assembly on slip ring  21  is transmitted via the base of great heat transfer capability and through the out surf ace of slip ring  26  as well as multiple slots to the atmosphere in order to lower the temperature of transparent package of illumination semiconductor  41 . 
     There are multiple annular surfaces of different diameters on out surface of fixed collar  36  of the rib members on fixed collar assembly  3 . A plurality of slots are fitted on one of the annular surface, on which fixed pins of ribs  171  are used to fix the ribs  17 . The rib members on fixed collar assembly  3  is fitted on the distal end of the shaft  11 , whose top circumferential surface of fixed collar  365  is stretched up through flexible canopy  10  and combined closely with fixed cover of flexible canopy  102  to prevent the rain from infiltrating into the inner section of umbrella. 
     The hollow top column  161  is installed on the upward stretched section of the rib members on fixed collar assembly  3 , located in the hole of top circumferential surface of fixed collar  365 , and is used to accommodate battery  151 , electric wire and holder of battery  152 . Holder of battery  152  is fitted with the battery positive and negative contacts, which are used to connect with power wire contact on fixed collar  341  and power wire contact on fixed collar  342 . 
     Spring  162  is installed inside the hollow top column  161  to make sure the battery is securely fixed. LED assembly on fixed collar  31  is fitted on the bottom circumferential surface of fixed collar  362  (not shown), connecting to electric contact on fixed collar  32  and electric contact on fixed collar  33 , respectively. LED assembly on fixed collar  31  is assembled in advance or is directly assembled on the base with transparent package of LED assembly on fixed collar  35  being completed subsequently with transparent materials. 
     LED assembly on fixed collar  31  connects with electric wire  131  and electric wire  132  at power wire contact on fixed collar  341  and power wire contact on fixed collar  342 , respectively. The circuit is made complete by electric wire on fixed collar  301  and electric wire on fixed collar  302 , which pass through the hole (not shown) on the base of shaft  11  to be welded to electric wire  131  (not shown) and electric wire  132  (not shown) at power wire contact on fixed collar  341  and power wire contact on fixed collar  342  on the top of the shaft. With the rib members on fixed collar assembly  3  having good thermal conductivity and the out surface of fixed collar  36  as well as the slots offering heat dissipation function, the heat of LED assembly on fixed collar  31  can be transmitted via these surfaces, thus lowering the temperature of transparent package of illumination semiconductor  41 . 
     When the umbrella is opened, linkage members on slip ring assembly  2  are moved up to be fixed in the open position of plate spring  112  on the shaft  11 . The open position of plate spring  1121  is fixed in the open slot of slip ring  283 , making electric contact on fixed collar  33  and electric contact on fixed collar  32  closer to the electric contact on slip ring  23  and electric contact on slip ring  22 , respectively, without direct contact. The circuit thus remains open. All the LED illumination components are not charged and do not light up. 
     As shown in  FIG. 21(   a ), when the umbrella is opened, linkage members on slip ring assembly  2  is moved up to be fixed in the close position of plate spring  112  on the shaft  11 . The close position of plate spring  1122  is fixed in the open slot of slip ring  283 , making electric contact on fixed collar  33  and electric contact on fixed collar  32  to join together with electric contact on slip ring  23  and electric contact on slip ring  22 , respectively, thus forming a closed circuit. All the LED illumination components will be charged and light up. 
     As shown in  FIG. 21(   b ), the embodiment is very suitable for usage at rainy days. By controlling the location setting of wire contacts for the circuit switch, power can be saved for umbrella when used in the daytime. Pressing switch  12  and long electric wire  13  can also be removed, so additional switch as seen in Reference Six and Reference Nine is not needed at all. 
     In summary, the versatility and design flexibility of the integrated illumination components of the present invention can be found in the above mentioned embodiments, which also present feasibility and significant improvements to currently known technical problems. More embodiments are expected to be discovered and realized. In addition, installation of the illumination emitter of LED for the integrated illumination components is highly flexible. While offering warning and safety functions, the illumination feature can also be used for color decoration and aesthetic expression together with the semi-transparent canopy and color LED illumination components. Utilizing umbrella parts of high heat dissipation capability as bases makes it more convenient for de signers and users to adopt the high-brightness LED illumination components and easier to meet their needs.
