Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 illustrates a schematic structural diagram of a bulb according to an embodiment of the present application. As shown in fig. 1, the bulb includes a light emitting component 1, a base 2 and a lamp housing 3, the light emitting component 1 is disposed inside the lamp housing 3 and electrically connected to the base 2, the lamp housing 3 is hermetically connected to the base 2, the lamp housing 3 is provided with a plurality of pinholes, each pinhole has a size less than or equal to 0.5mm, and the base 2 is electrically connected to the lamp cap.

In the embodiment of the application, the light emitting component 1 is arranged in the lamp housing 3, and the lamp housing 3 is hermetically connected with the lamp holder 2, so that the light emitting component 1 is prevented from being in direct contact with the external environment, the light emitting component 1 is protected, and the power supply for the light emitting component 1 can be realized through the electric connection between the light emitting component 1 and the lamp holder 2, so that the bulb can normally emit light for illumination. The plurality of pinholes are arranged on the lamp housing 3, so that the heat emitted by the light-emitting component 1 can be discharged through the plurality of pinholes. Because the size of each pinhole is less than or equal to 0.5mm, the attractive force of the surface of the lamp shell 3 provided with a plurality of pinholes to water is far less than the surface tension of the water, so that the lamp shell 3 of the bulb is not easy to be stained with water, and the water prevention and heat dissipation of the bulb can be realized simultaneously.

As shown in fig. 1, the base 2 may be a screw base 2 and has a waterproof function. Therefore, the bulb can be conveniently matched with a common lamp holder, and moisture can be prevented from entering the bulb from the lamp holder 2 to damage the bulb. Of course, the base 2 may also be another base 2, such as a bayonet base 2, as long as the matching with the lamp holder can be realized conveniently, and the waterproof performance is convenient, which is not limited in the embodiment of the present application.

For example, each pinhole may be 0.25mm in size, so that the influence on the light beam emitted from the light emitting assembly 1 may be reduced while facilitating heat dissipation and waterproofing of the light emitting assembly 1, so that the light beam emitted from the light emitting assembly 1 may uniformly penetrate through the lamp housing 3. Of course, the size of each pinhole may also be other sizes, such as 0.2mm, 0.3mm, or 0.35mm, as long as the size of each pinhole is less than or equal to 0.5mm, which is not limited in the embodiments of the present application.

In some embodiments, a distance between any two adjacent pinholes in the plurality of pinholes may be greater than or equal to 1.5mm, for example, a distance between any two adjacent pinholes may be 2mm, 3mm, or 5mm, etc.

Like this, can make there is the lamp body 3 of certain area between two arbitrary adjacent pinholes to form the support to the pinhole, when lamp body 3 received the exogenic action, the lamp body 3 of certain area that every pinhole periphery exists can carry out abundant dispersion to the power that this pinhole received, in order to prevent the concentration of the power that this pinhole and adjacent pinhole received, thereby can guarantee the quality of lamp body 3, and then can promote the life of lamp body 3.

In some embodiments, as shown in fig. 1, the plurality of pinholes may be uniformly distributed on the lamp envelope 3, and the distance between any two adjacent pinholes may be between 1.5mm and 3.5 mm. For example, the distance between any two adjacent pinholes can be 2mm, 2.5mm or 3mm, etc.

Like this, when lamp body 3 received the exogenic action, because a plurality of pinholes evenly distributed on lamp body 3, the power that consequently every pinhole on the lamp body 3 received equals to can avoid the power on the lamp body 3 to concentrate around certain pinhole, and make lamp body 3 break from this pinhole, thereby can guarantee the quality of lamp body 3. Meanwhile, the distance between any two adjacent pinholes on the lamp housing 3 is less than or equal to 3.5mm, so that the number of the pinholes on the lamp housing 3 can be increased, the light-emitting assembly 1 in the lamp housing 3 can fully dissipate heat, and the heat dissipation effect of the lamp housing 3 can be improved.

In other embodiments, as shown in fig. 2, a plurality of pin holes may be provided on the side of the lamp envelope 3 to which the base 2 is connected. Like this, can make a plurality of pinholes be close to light emitting component 1 to reduce the heat that light emitting component 1 produced and transmit the distance to the external world in from lamp body 3, and then reduce the heat that light emitting component 1 produced and the time of detaining in lamp body 3, thereby can improve the heat that light emitting component 1 produced and spread the efficiency to the external world in lamp body 3, improve the radiating effect of lamp body 3.

In this way, the space between the two helical pinholes can be used to guide the water or other fluid adhering to the lamp envelope 3, so that the water adhering to the lamp envelope 3 can be quickly drained away.

Further, the lead of each helical structure may be 1/3 of the distance between the end of the lamp housing 3 close to the socket 2 and the end far from the socket 2, so as to ensure that the time for the water attached to the lamp housing 3 to flow on the lamp housing 3 is short, and the water attached to the lamp housing 3 can be discharged more quickly. Of course, the lead of each helical structure may be other leads as long as it is convenient for the water attached to the lamp housing 3 to be discharged, and this is not limited in the embodiment of the present application.

In still other embodiments, as shown in fig. 4, the lamp housing 3 may have a conical structure, and the plurality of pinholes are distributed along the generatrix direction of the lamp housing 3, and at least one pinhole is distributed in each generatrix direction. Therefore, the bulb can realize water resistance and heat dissipation, and meanwhile, the attractiveness of the bulb can be improved.

For example, the plurality of pinholes may be divided into five groups, the number of each group of pinholes is equal, the five groups of pinholes are uniformly distributed along the bus direction of the lamp housing 3, of course, the plurality of pinholes may also be divided into other number of groups, such as three groups, six groups, eight groups, etc., and the number of each group may also be different, and the specific grouping situation is determined according to the actual situation, which is not limited in the embodiment of the present application.

The lamp housing 3 may have a tapered structure, or may have another structure, such as a cylindrical structure, a prismatic structure, or a rectangular parallelepiped structure. When the lamp housing 3 is prismatic, the number of groups into which the plurality of pinholes can be divided may be a multiple of the number of cylindrical surfaces of the prismatic lamp housing 3, so that the aesthetic appearance of the lamp housing 3 may be improved.

It should be noted that, besides the four regular distributions on the lamp housing 3, the pin holes may also be distributed randomly on the lamp housing 3, and the distribution density of the side close to the base 2 is greater than that of the side far from the base 2, which also facilitates the diffusion of the heat generated by the light emitting assembly 1. Of course, the distribution may be according to other rules, which is not limited in the embodiments of the present application.
