Description

LED light bulb

The present invention relates to a light bulb, in particular to a light-emitting diode light bulb.

Light-emitting diodes have the advantages of high luminous efficiency, low power consumption, long service life and low operating temperature. Under the same brightness, the power consumption of light-emitting diodes is one-tenth of that of incandescent lamps. Fluorescent lamps One-third of the light-emitting diodes, but the life span is 50 times that of incandescent lamps and 20 times that of fluorescent lamps. Therefore, light-emitting diodes are currently widely used in light bulbs.

Please refer to FIG. 6, which is a front view of a conventional light-emitting diode bulb. As shown in FIG. 6, although the light-emitting diode bulb 5 in FIG. 6 is provided with a plurality of light-emitting diodes 51, the effect of improving the brightness of the light can be achieved. However, since the light-emitting diode 51 itself has a certain weight, if only the two wires 52 and 53 connecting the positive and negative electrodes in the diagram are connected to the two ends of the light-emitting diode 51, the spiral structure of the light-emitting diode cannot be maintained, and It is easy to be unable to stabilize the LED 51 inside the lamp housing 54 of the 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 light-emitting diode bulb. As shown in FIG. 7, the light-emitting diode 61 is disposed on the electrical connection portion 62 at the bottom of the light-emitting diode bulb 6, and transmits the light emitted by the light-emitting diode 61 through the optical fiber 63 connected to the light-emitting diode 61. However, the light-emitting diode bulb 6 that only uses a single light-emitting diode 61 and an optical fiber 63 to emit light is far inferior to the light bulb that directly emits light with multiple light-emitting diodes in terms of the brightness of the indirect light through the optical fiber. The effectiveness of luminescence is not as good as that of direct lighting as shown in Figure 6.

Please refer to FIG. 8, which is a three-dimensional schematic diagram of another conventional light-emitting diode lamp. It can be clearly seen in Fig. 8 that the outer diameter 81D of the fixing frame 81 of the light-emitting diode lamp must be smaller than the inner diameter 82D of the neck 82, so that the fixing frame 81 structure preset on the outside of the lamp housing can penetrate into the neck 82 in advance. Set inside the lamp housing. Under this restriction, if the number of LED strips is to be increased to increase the brightness of the LED bulb, it is necessary to install long and multiple LED strips in the direction perpendicular to the inner diameter of the neck. However, this arrangement structure will easily form a dead zone of light on the upper and lower sides of the bulb.

Please refer to FIG. 9, which is a three-dimensional schematic diagram of another conventional light-emitting diode lamp. In the structure of FIG. 9, in order to solve the problem that the structure of FIG. 8 easily produces dark areas on the upper and lower sides of the bulb, a support 93 having a horizontal portion 931 and an upright portion 932 is used to support the light-emitting diode light source 90. .

In this embodiment, the structure of the light-emitting diode bulb 1 in FIG. 1 is taken as an example. Other light-emitting diode bulbs with the light-emitting diode structure are similar to this method, and will not be repeated here.

In FIG. 5A, since the electrical connection part of the light-emitting diode bulb 1 has not been coupled to the neck 112, the light-emitting diodes that have been connected to the first conductive rod 133, the second conductive rod 134, and the support rod 132 can be connected first. The main body 12 is inserted into the receiving portion 111 of the lamp housing 11 through the opening of the neck 112 in a direction perpendicular to the inner diameter D1 of the neck 112 of the light-emitting diode bulb 1. It should be noted that since the body length L1 of the light-emitting diode body 12 is greater than the inner diameter D1 of the neck 112, the light-emitting diode body 12 must be placed in the accommodating portion 111 of the lamp housing 11 in a vertical direction.

The pole body is arranged in the lamp housing. On the contrary, the present invention breaks through this limitation, so that the support frame and the light-emitting diode whose length is greater than the inner diameter of the neck of the lamp housing can still be arranged in the lamp housing without being limited by the size limit of the inner diameter of the neck of the lamp housing. And it is arranged in a direction parallel to the inner diameter of the neck, and the length of the support frame and the light-emitting diode is larger than the size of the neck in the projection direction parallel to the inner diameter of the neck. supporting structure. In addition. Therefore, the light-emitting diode bulb in this case also overcomes the limitation of the inner diameter of the penetrating neck, so that there is sufficient light in front of the bulb without generating a dark area.
