Description

light bulb

This creation is especially about a light bulb.

With the advancement of technology, people pay more and more attention to energy conservation and environmental protection. Traditional tungsten filament bulbs have gradually been eliminated, so people began to change the traditional tungsten filament bulbs on the lamp holders to LED bulbs. Generally, the LED light bulb is provided with at least one LED chip on the pedestal, and a lamp cover is further disposed on the pedestal, so that the at least one LED chip is disposed between the pedestal and the lamp cover. Light bulbs disclosed in TWI463706 and M499519 are such.

However, the light source of such an LED bulb has a high directivity. Therefore, when the LED chip, the lamp holder and the lamp cover are assembled, the light source is mostly concentrated above the lamp cover, resulting in uneven light distribution during external viewing. The lampshade will be very glaring, and there are drawbacks that need to be improved.

Therefore, it is necessary to provide a novel and progressive light bulb to solve the above problems.

The main purpose of this creation is to provide a bulb that can be formed by a filament of a filament such as a tungsten filament lamp, which complements the conventional illumination of the LED bulb.

To achieve the above object, the present invention provides a light bulb including a base and a lamp cover. One side of the base is provided with at least one LED filament, the at least one LED filament and the base The base is electrically connected to the external power source; the lamp cover is disposed on the base, and the at least one LED filament is disposed between the base and the lamp cover.

The bulb 1 further includes a bracket 21 protruding from the base 10 toward the shade 20, and the LED filaments 30 are mounted on the bracket 21 The bracket 21 is disposed between the base 10 and the lamp cover 20, and each of the LED filaments 30 is gradually inclined toward the bracket 21 in a direction away from the base 10, so that the bracket 21 can be The bulb 1 achieves a multi-directional (lateral and upper) illumination effect, resulting in a more even distribution of light.

More specifically, each of the LED filaments 30 has a first end 31 and A second end 32, the first end 31 is away from the base 10, and the second end 32 is adjacent to the base 10. The LED filament 30 includes a first electrode 310, a second electrode 320 and a substrate 35. The first electrode 310 is disposed at the first end 31; the second electrode 320 is disposed at the second end 32; the substrate 35 is disposed between the first electrode 310 and the second electrode 320. The substrate 35 is provided with at least one LED chip 350. The at least one LED chip 350 is electrically connected to the first electrode 310 and the second electrode 320. One of the first electrode 310 and the second electrode 320 is connected to the base. One of the positive poles is electrically connected to the other, and the other is electrically connected to one of the negative poles of the base 10, so that a complete electrical circuit can be formed; more specifically, the base 10 includes at least one The circuit module can convert the alternating current into direct current. Therefore, the first electrode 310 and the second electrode 320 are electrically connected to the positive and negative electrodes of the circuit module inside the base 10. In more detail, the substrate 35 is provided with a plurality of LED chips 350 connected in series on one side; it can be understood that LED chips can be disposed on both sides of the substrate to achieve better illumination effects.

Further, each of the LED filaments 30 further includes a phosphor layer 36, the phosphor The glue layer 36 is at least partially disposed on the substrate 35 and the at least one LED chip 350. Thus, the light emitted by each of the LED chips 350 can pass through the phosphor layer 36 to change the color of the light. It can be understood that the phosphor layer can be changed to other materials such as an optical fiber, and only one LED chip needs to be disposed on one side of the fiber, and the light can be illuminated by the entire fiber due to total reflection.

In this embodiment, the LED filaments 30 of the bulb 1 are in groups of two The first ends 31 of the LED filaments 30 are electrically connected to each other by a first wire 33. The second ends 32 of the two LED filaments 30 are electrically connected to the base 10 by a second wire 34. The first lead 33 is electrically connected to the two first electrodes 310, and each of the second leads 34 is electrically connected to each of the second electrodes 320. Understandably, the bulb can also have only one LED filament. The two ends of the LED filament are electrically connected to the positive and negative poles of the base respectively.
