Power saving light bulb

The invention relates to a power-saving bulb, in particular to a power-saving bulb which is fixedly fixed by a spiral tube and a lamp holder to improve the overall mechanical strength.

With the rapid development of the economy, people are increasingly increasing their energy consumption, so modern society is more about green and environmental protection. Electrical products that demand energy-saving and power-saving are therefore very popular. After the development of the energy-saving light bulb, due to its long life, good efficiency and high brightness, it has replaced the traditional fluorescent lamps and become the new favorite of indoor and outdoor lighting. Currently, the commercially available power-saving bulbs include spiral-type power-saving bulbs and U-type power-saving bulbs, among which spiral-type power-saving bulbs are more common.

As shown in Figure 1, the energy-saving bulb 1 with the spiral tube 2 on the market has a fixed position of the spiral tube 2 and the lamp holder 3. Most of them are vertically inserted, which is easy to loose and less stable; "Figure 2" Then, the other type of the power-saving bulb 4 fixes the spiral lamp tube 5 and the lamp holder 6 through the two spiral portions 7, so that the spiral lamp tube 5 is inserted into the lamp holder 6 in the spiral direction. However, the above-mentioned method of fixing only the spiral lamp and the lamp holder has insufficient overall mechanical strength, and is not stable and easy to loose. When replacing the bulb, if you hold the screw directly at the screw, it is easy to loosen the spiral tube from the lamp holder or twist the spiral tube. Therefore, most of the power-saving bulbs are designed with a transparent lampshade attached to the lamp holder, so that the user does not have to directly apply force to the fragile spiral lamp, and indirectly transmits the power-saving bulb into or out of the lighting device by applying force to the transparent lampshade.

However, the above solution to the external lampshade will give rise to another layer of problems. For example, although the lampshade is transparent, it will reduce the luminous brightness of the overall power-saving bulb or block the heat dissipation of the spiral lamp, so that thermal energy accumulates inside the bulb, which affects the luminous efficiency and even shortens the service life of the energy-saving bulb. Therefore, other solutions are needed to increase the strength of the spiral tube and the lamp holder without using a transparent lamp cover.

The object of the present invention is to provide a power-saving light bulb, which can enhance the strength and stability of the combination between the spiral lamp tube and the lamp holder. In the case of not using the transparent lamp cover, the light bulb can be directly rotated without considering the connection between the spiral lamp tube and the lamp holder. Loose problem.

In order to achieve the foregoing object, the present invention additionally fixes the spiral lamp tube to the spiral portion after the spiral lamp tube is inserted into the lamp holder, thereby enhancing the strength and stability after the combination of the two. In one embodiment, the present invention utilizes an adhesive to adhere the spiral tube to the spiral portion to form an adhesive portion; in another embodiment, the spiral portion includes an outer groove corresponding to the outer circumference of the spiral tube, resulting in The spiral tube can be engaged with the outer groove to fix the spiral tube to the spiral portion; in another embodiment, the spiral tube is inserted into the socket, and a fixing reinforcement member is provided to increase the tube and the lamp. The fixing strength of the seat; in another embodiment, the bonding method, the outer groove or the fixing reinforcement are combined to further increase the overall mechanical strength.

Compared with the conventional power-saving bulb, the power-saving bulb of the present invention has high mechanical strength, and the user can directly rotate the bulb portion without being restricted by the use of the transparent lamp cover, thereby increasing the luminous efficiency.

The fixing reinforcement 50 includes an insertion portion 51, a hole 52 and a support portion 53. The fixing reinforcement member 50 is received in the insertion hole 312 through the insertion portion 51 and is not easily detached. The spiral lamp tube 20 is inserted into the spiral portion 311 from the hole 52 along the spiral direction, and the support portion 53 has a spiral lamp. The arcuate groove corresponding to the outer circumference of the tube 20 can support and accommodate the spiral lamp tube 20 and enhance the bonding strength between the spiral lamp tube 20 and the lamp holder 30. The material of the fixing reinforcement 50 is not limited, and may be, for example, metal or high temperature resistant plastic or rubber.

As described above, the present invention can improve the power-saving bulb by applying an adhesive to the spiral portion 311 and a part of the tube of the spiral tube 20, providing the outer groove 313 in the spiral portion 311, or adding a fixing reinforcement 50. The bonding strength of 10, the above three methods can be used together or together. FIG. 9 is a perspective view showing the appearance of the fourth embodiment of the present invention. The present embodiment is combined with the arrangement of the adhesive portion 40a, the adhesive portion 40b and the outer groove 313 to enhance the overall mechanical strength of the power-saving bulb 10. In this embodiment, the spiral portion 311 has an outer groove 313 corresponding to the outer circumference of the spiral tube 20, so that the spiral tube 20 can be engaged with the outer groove 313, and the spiral tube 20 is inserted into the socket. After 30, at least one of the spiral portions 311 and the spiral tube 20 are bonded to each other to form an adhesive portion 40a. In addition, the portions where the two spiral portions 311 are in contact with the spiral tube 20 may be completely or partially bonded together. In this embodiment, an adhesive is further applied between the insertion end 201 and the inner wall of the insertion hole 312, so that the insertion end 201 and the insertion hole 312 are inserted into each other to form the adhesive portion 40b, so that the spiral tube is The connection to the spiral portion 311 is more stable.
