Abstract
The invention relates to the lighting technology field, in particular to a self-ballasted fluorescent lamp which comprises a lamp tube body, a lamp holder and a circuit board module. A containing cavity is arranged in the lamp holder. The circuit board module is arranged in the containing cavity. A plurality of heat dissipation holes are formed in the lamp holder. A stopping block is arranged in the containing cavity. The stopping block is arranged below the heat dissipation holes. Heat generated by the lighting self-ballasted fluorescent lamp is capable of causing the temperature in the containing cavity of the lamp holder to heat up and can be radiated out of the containing cavity through the dissipation holes, and thereby the self-ballasted fluorescent lamp has the advantages of effectively reducing the temperature in the containing cavity, protecting the circuit board module and prolonging service life of the circuit board module. Due to the fact that the stopping block is capable of effectively preventing the outside dust from entering into the containing cavity through the dissipation holes, and thereby the circuit board module is prevented from being coated with dust and service life of the circuit board module is prolonged.
Description
Technical field
The present invention relates to lighting technical field, particularly a kind of self-ballasted fluorescent lamp.
Background technology
At present, the electronic energy-saving lamp that illumination namely is commonly called as with self-ballasted fluorescent lamp with the bright advantage of its power saving, just is being widely used in various occasions.The characteristics of this lamp are that wiring board that fluorescent tube and ballast are used, lamp holder, plastic housing etc. are assembled together, volume compact, the transportation and install and use all more convenient, but the disadvantage of this lamp is that fluorescent tube and ballast are assembled together close together, the fluorescent tube evolution of heat when lighting a lamp, greatly aggravate the temperature rise of ballast, thereby cause the life-span of the more inner temperature-sensing element (device)s of ballast greatly to shorten, more obvious on the impact of the larger lamp of power.
Summary of the invention
The present invention is in order to solve that present self-ballasted fluorescent lamp exists because circuit board is built in the accommodating cavity of lamp holder, the heat that sends when fluorescent lamp is luminous rises accommodating cavity temperature, and cause the problem of the electronic devices and components lost of life, and a kind of self-ballasted fluorescent lamp that provides.
For reaching above-mentioned functions, technical scheme provided by the invention is:
A kind of self-ballasted fluorescent lamp, comprise lamp tube body, lamp holder and circuit board assemblies, described lamp holder is provided with accommodating cavity, described circuit board assemblies also is arranged at respectively in the accommodating cavity of described two ends lamp holder by first circuit board assembly and second circuit board module composition, described lamp holder is provided with a plurality of louvres, be provided with block in described accommodating cavity, described block is positioned at the below of described louvre.
Preferably, the material of described lamp holder is ABS or PBT.
Preferably, described louvre is square opening.
Beneficial effect of the present invention is: by at described lamp holder a plurality of louvres being set; the heat that the accommodating cavity temperature that causes lamp holder that produces when making self-ballasted fluorescent lamp luminous rises can be dispersed into outside the accommodating cavity by louvre; thereby can effectively reduce the temperature in the accommodating cavity; the holding circuit board component; prolong the life-span of circuit board assemblies; in described accommodating cavity, also be provided with simultaneously block; described block is positioned at the below of described louvre; by this design; block can effectively block extraneous dust and enter in the accommodating cavity by louvre; thereby prevent that circuit board assemblies is stained with dust, and then prolong the life-span of circuit board assemblies.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of lamp holder.
The specific embodiment
The present invention is further elaborated below in conjunction with accompanying drawing 1 and accompanying drawing 2:
A kind of self-ballasted fluorescent lamp as shown in Figure 1, comprise lamp tube body 1, lamp holder 2 and circuit board assemblies 3, lamp holder 2 is provided with accommodating cavity 4, circuit board assemblies 3 is made of first circuit board assembly 31 and second circuit board component 32 and is arranged at respectively in the accommodating cavity 4 of fluorescent lamp two ends lamp holder 2, lamp holder 2 is provided with a plurality of louvres 21, be provided with block 22 in accommodating cavity 4, block 22 is positioned at the below of louvre 21.
Because lamp holder 2 place's temperature are higher and often be subjected to irradiation, for improving the service life of fluorescent lamp, lamp holder 2 needs to adopt the material of high-fire resistance and weatherability to make, and in the present embodiment, that the material of lamp holder 2 adopts is PBT.Certainly lamp holder 2 also can be made with the material of other high-fire resistance and weatherability such as ABS etc.
As shown in Figure 2, for improving the aesthetics of product appearance, also be beneficial to setting and the moulding of block 22 simultaneously, in the present embodiment, louvre 21 is square openings.
The above embodiment, it is preferred embodiments of the present invention, be not to limit practical range of the present invention, so all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, all should be included in the patent claim of the present invention.
