Description

Light-emitting diode bulb
Technical Field
The present invention relates to a light bulb, and more particularly to a light emitting diode light bulb.
Background
The LED has the advantages of high luminous efficiency, low power consumption, long service life and low operating temperature, and under the same brightness, the power consumption of the LED is one tenth of that of an incandescent lamp and one third of that of a fluorescent lamp, but the service life of the LED is 50 times that of the incandescent lamp and 20 times that of the fluorescent lamp, so that the LED is widely applied to the bulbs at present.
Please refer to fig. 6, which is a front view of a conventional led bulb. As shown in fig. 6, although the led bulb 5 in fig. 6 is provided with a plurality of leds 51, the effect of increasing the brightness of the emitted light can be achieved. However, since the led 51 has a certain weight, if only two wires 52 and 53 connecting the positive and negative electrodes in the drawing are connected to two ends of the led 51, the spiral structure of the led cannot be maintained, and the led 51 cannot be stably fixed inside the lamp housing 54 of the light bulb due to insufficient supporting force of the wires 52 and 53.
Please refer to fig. 7, which is a front view of another conventional led bulb. As shown in FIG. 7, the LED 61 is disposed on the electrical connection portion 62 at the bottom of the LED bulb 6, and the light emitted from the LED 61 is transmitted through the optical fiber 63 connected to the LED 61. However, the LED bulb 6 using only a single LED 61 and an optical fiber 63 to emit light is far less bright than the bulb directly emitting light with multiple LEDs, and the light emitting efficiency is not as good as that of the direct illumination of FIG. 6.
Please refer to fig. 8, which is a perspective view of another conventional led lamp. In fig. 8, it can be clearly seen that the outer diameter 81D of the fixing frame 81 of the led lamp must be smaller than the inner diameter 82D of the neck portion 82, so that the fixing frame 81 structure preset outside the lamp housing can be inserted into the neck portion 82 and disposed inside the lamp housing. Under the limitation, in order to increase the number of led light bars to increase the brightness of the led light bulb, a long led light bar or a plurality of led light bars must be installed in a direction perpendicular to the inner diameter of the neck. However, this arrangement tends to create dark areas (dead zones) of illumination on the upper and lower sides of the bulb.
Please refer to fig. 9, which is a perspective view of another conventional led lamp. In the structure of fig. 9, in order to solve the problem that dark areas are easily generated on the upper and lower sides of the bulb in the structure of fig. 8, the led light source 90 is supported by a supporting member 93 having a horizontal portion 931 and a vertical portion 932. However, this structure is still limited by the inner diameter of the neck, thereby further limiting the length of the LED light bar.
Accordingly, it is an object of the present invention to provide an internal structure of a light emitting diode bulb and a new manufacturing method thereof to improve the above problems.
