Abstract
The utility model discloses an easily cooled energy-saving lamp. The easily cooled energy-saving lamp is characterized in that: the lamp comprises a lamp holder, a shell and a lamp tube; the lamp holder is arranged on the top of the shell; the lamp tube is arranged on the bottom of the shell; a circuit is arranged in the shell; the shell is composed of the upper part and the lower part; the top of the lower part is connected with the bottom of the upper part, and the top of the lower part is smaller than the bottom of the upper part; inwards concaved annular grooves are formed around the bottom of the upper part; cooling holes are formed on the bottom surfaces of the annular grooves; inside diameters of the annular grooves are greater than the outside diameter of the lower part. The cooling holes of the easily cooled energy-saving lamp disclosed by the utility model are formed in the annular groove, so that less dust enters the cooling holes and damage caused by the dusts of the energy-saving lamp is reduced.
Description
Technical field
The utility model relates to a kind of electricity-saving lamp of easy heat radiation, be specifically related to a kind of electricity-saving lamp.
Background technology
Electricity-saving lamp in the technology generally is made of lamp holder, shell, fluorescent tube now, has circuit in the shell.Electricity-saving lamp is in the process of work, and the element in its inner circuit can generate heat, and it is excessive to generate heat, or heat can not in time come out, can directly influence the work of electricity-saving lamp, perhaps its life-span, so electricity-saving lamp generally all is provided with louvre, the louvre of the electricity-saving lamp of prior art generally directly is located at the perisporium of its shell, but the defective of this kind electricity-saving lamp is that dust enters inside by louvre easily, the easy circuit that pollutes of long-pending many dusts meetings, cause short circuit, electricity-saving lamp is damaged.
The utility model content
The utility model technical issues that need to address provide a kind of electricity-saving lamp of easy heat radiation, and this kind electricity-saving lamp can reduce dust and enter, and reduce the damage that electricity-saving lamp causes because of dust.
The utility model technical solution problem can be by taking following technical scheme:
A kind of electricity-saving lamp of easy heat radiation is characterized in that: comprise lamp holder, shell, fluorescent tube, lamp holder is located at the top of shell, and fluorescent tube is located at the bottom of shell, has circuit in the shell; Described shell is made of the upper and lower, the top of bottom is connected with the bottom on top, and the top of bottom is littler than the bottom on top, and the bottom periphery on top is provided with inwardly recessed cannelure, the bottom surface of cannelure is provided with louvre, and the internal diameter of cannelure is bigger than the external diameter of bottom.
The utility model technical solution problem can also further be taked following corrective measure:
Between the top of described bottom and the bottom on top by being threaded.
The utlity model has following technique effect:
The utility model easily louvre of the electricity-saving lamp of heat radiation is opened in cannelure, no matter be that electricity-saving lamp traverse or fluorescent tube court transfer, worked as by the cannelure resistance, louvre does not all have vertically to open wide towards last, when the dust gravitate moves downward, can not fall in the louvre, can reduce dust and enter louvre, reduce the damage that electricity-saving lamp causes because of dust.
Description of drawings
Fig. 1 is the easily structural representation of the electricity-saving lamp of heat radiation of the utility model.
Fig. 2 is the easily bottom view of the electricity-saving lamp of heat radiation of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Embodiment: as shown in Figure 1 and Figure 2, a kind of electricity-saving lamp of easy heat radiation comprises lamp holder 1, shell 2, fluorescent tube 3, and lamp holder 1 is located at the top of shell 2, and fluorescent tube 3 is located at the bottom of shell 2, has circuit in the shell 2; Described shell 2 is made of top 4 and bottom 5, the top of bottom 5 is connected with the bottom on top 4, and the top of bottom 5 is littler than the bottom on top 4, and the bottom periphery on top 4 is provided with inwardly recessed cannelure 6, the bottom surface of cannelure 6 is provided with louvre 7, and the internal diameter of cannelure 6 is bigger than the external diameter of bottom 5.
Between the bottom on the top of described bottom 5 and top 4 by being threaded.
The utility model easily louvre of the electricity-saving lamp of heat radiation is opened in cannelure, can reduce dust and enter louvre, reduces the damage that electricity-saving lamp causes because of dust.
Claims (2)
1. easy electricity-saving lamp of heat radiation, it is characterized in that: comprise lamp holder, shell, fluorescent tube, lamp holder is located at the top of shell, and fluorescent tube is located at the bottom of shell, has circuit in the shell; Described shell is made of the upper and lower, the top of bottom is connected with the bottom on top, and the top of bottom is littler than the bottom on top, and the bottom periphery on top is provided with inwardly recessed cannelure, the bottom surface of cannelure is provided with louvre, and the internal diameter of cannelure is bigger than the external diameter of bottom.
