Abstract
Description
- The present invention relates to a light-emitting diode (LED) light bulb structure and, more particularly, to an LED filament light bulb with a mounting structure of multiple layers of juxtaposed LED filaments.
- The techniques associated with LED light bulb structure never stop their footstep in progress. Current LED light bulbs in the market usually have multiple series-parallel connected LEDs for the purpose of higher luminance. Printed circuit board has been brought into play in the current technique to facilitate the arrangement of circuit loops. For example, as disclosed in
Taiwan Utility Model Patent No. M389204 - Another current technique associated with LED light bulb pertains to a type of LED filament light bulb. With reference to
Fig. 5 , a conventional LED filament light bulb includes aglass body 10a, aglass stem 20a, afirst power wire 21 a, asecond power wire 22a, aglass bar 100, aglass head 120,multiple filaments 101∼108, a firstlower loop frame 124, a secondlower loop frame 126 and twoupper loop frames - The
glass body 10a is sealed, is vacuumed internally, and is filled with inert gas for heat dissipation. Theglass stem 20a is mounted inside theglass body 10a and is located on a bottom of theglass body 10a. Thefirst power wire 21a and thesecond power wire 22a are mounted in theglass stem 20a and protrude beyond theglass stem 20a. Exposed portions of thefirst power wire 21a and thesecond power wire 22a are respectively connected to the firstlower loop frame 124 and the secondlower loop frame 126. Theglass bar 100 is formed on and vertically protrudes from a top end of theglass stem 20a. Theglass head 120 is mounted on a top of theglass bar 100 and is coupled to theupper loop frames upper loop frames glass head 120. Top ends of one half of themultiple filaments 101∼104 are coupled to one of theupper loop frames 122a, and bottom ends of the half of themultiple filaments 101∼104 are coupled to the firstlower loop frame 124. Top ends of the other half of themultiple filaments 105∼108 are coupled to the otherupper loop frame 122b and bottom ends of the half of themultiple filaments 105∼108 are coupled to the secondlower loop frame 126. - However, the conventional LED filament light bulb has the following drawbacks.
- 1. As a center support, the
glass bar 100 is fragile and is vulnerable to support the overall weight of the multiple LEDs and an associated structure and withstand vibration arising from the overall weight. Suppose that an increase in luminance is a concern. In view of the structural limitation, LED filaments fail to be added by means of multiple LED modules stacked to each other. Therefore, the number of LEDs can't be increased through the modular approach. - 2. As LED circuit prefers to have parallel connection, according to the conventional filament light bulb in
Fig. 5 , parallel circuit connection is not easy to be implemented because theLEDs 101∼108 are far from thefirst power wire 21a and thesecond power wire 22a. - 3. To increase the number of LEDs, more breakpoints must exist. Such necessity results in a loose structure that causes a shakable power wire connection structure and vibration of the filaments, rendering the entire filament-supporting structure insecure.
- An objective of the present invention is to provide an LED light bulb structure with at least one light-emitting module, in which the at least one light-emitting module is arranged in a modular form and stacked to each other for easy expansion thereof and multiple LED filaments in each light-emitting module are connected in series to ensure increase in luminance and LED light bulb structures customized in terms of different luminance and different wattage according to desired shapes of the lamp body.
- To achieve the foregoing objective, the light-emitting diode (LED) light bulb structure includes a glass stem, a first power wire, a second power wire, a first conducting bar, a second conducting bar and a first light-emitting module.
- The first power wire and the second power wire are mounted in the glass stem with one end of each of the first power wire and the second power wire protruding beyond the glass stem.
- The first conducting bar has one end thereof connected with the end of the first power wire protruding beyond the glass stem.
- The second conducting bar has one end thereof connected with the end of the second power wire protruding beyond the glass stem.
- The first light-emitting module has a top horizontal bar assembly, a bottom horizontal bar assembly, multiple fixing balls and multiple LED filaments.
- One end of each of the top horizontal bar assembly and the bottom horizontal bar assembly is connected with the first conducting bar, and the other end of each of the horizontal bar assembly and the bottom horizontal bar assembly is connected with the second conducting bar.
- The multiple fixing balls are mounted on the top horizontal bar assembly and the bottom horizontal bar assembly and are spaced apart to form multiple breakpoints.
- The multiple LED filaments are mounted between the top horizontal bar assembly and the bottom horizontal bar assembly to form an alternating U-shaped series-connected circuit loop passing through the multiple LED filaments and the top horizontal bar assembly and the bottom horizontal bar assembly.
- Given the design of the modular light-emitting modules and the conducting bars providing supporting and conducting functions, the light-emitting modules are more structurally stable and can be expanded based on users' demands, thereby enhancing luminance of the stackable light-emitting modules, facilitating the manufacture of the LED light bulbs, and effectively raising the production yield of the LED light bulbs. Additionally, the multiple fixing balls serve both as breakpoints of the power supply circuit loop and as elements good for building the light-emitting modules with higher structural strength.
- Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
