Abstract

The utility model provides a high-strength gas discharge lamp with a built-in electronic ballast, which comprises a lamp shell, a lamp bulb, a lamp column and an electron ballast. The utility model is characterized in that one plane of the electron ballast is arranged on one plane inside the lamp shell or the lamp column, and the plane of the electron ballast and the plane inside the lamp shell or the lamp column are fastened together through the fasteners. The technical scheme has the characteristic that heat quantity generated by the electron ballast is emitted through the plane contact between the electron ballast and the lamp shell or the lamp column of the high-strength gas discharge lamp through heat conduction. Proved by practice, the method of the utility model can make the temperature rise of the electron ballast kept within a constant range, the electron ballast can be avoided to be solarized and drenched, the working stability is raised, and the service life is extended; besides, a low-energy consumption electron ballast can be generalized and applied, and the energy saving is achieved.

Description

The high-intensity gas discharge lamp that electric ballast is built-in

Affiliated technical field

The utility model relates to illuminating lamp, the built-in high-intensity gas discharge lamp of particularly a kind of electric ballast.

Background technology

High intensity discharge such as high-pressure mercury lamp, metal halide lamp lamp (HID) is an energy-conservation light emitting source newly developed in recent years, its energy consumption is low, brightness big, volume is again little, can be that people create a light and beautiful living environment at night, be subjected to very much people's welcome, just applied in the many cities of China.Yet, not enough is this lamp supporting ballast be inductance type ballast, this inductance type ballast power consumption is big, there is nearly 50% electric energy to slattern in vain, therefore, under the very nervous situation of current China power supply, still a large amount of electric energy of the inevitable loss of this traditional ballast of adapted, high-intensity gas discharge lamp is energy-conservation, and ballast consumes energy, and this is a very thing of contradiction.Though it is the electric ballast desire that also has many producers to develop a kind of low energy consumption at present replaces inductance type ballast, actual even to this day that use and few.Tracing it to its cause is the restriction that the design of electric ballast still is subjected to environment for use, and volume must be little, and cost performance is low again, and therefore existing electric ballast itself can not be taked special cooling measure, only outer shell heat radiation.As you know, electric ballast works in high-power, the heat that produces during work is bigger, it is a thermal source, it is inappropriate adopting conventional assembly method to be placed in the interior fluorescent tube with heating of lamp body together, can make the electronic ballast actuator temperature sharply raise, therefore present way is that ballast is hung on outside the lamp body, generally be to hang on the lamppost, rely on cross-ventilation that its heat is taken away, still, place the outer electric ballast of lamp body can run into such problem again: owing to expose to the sun and rain for a long time, endure the hardships rain and dew to the fullest extent, the infringement that severe cold is extremely hot and the impact of thunder and lightning greatly reduce the reliability of work, have shortened service life, and hang on the lamppost and also be repugnant to the eye, these drawbacks influence the whereabouts that electric ballast is difficult to apply just.

Summary of the invention

In order to solve the above-mentioned defective that prior art exists, the utility model provides a kind of electric ballast built-in high-intensity gas discharge lamp, this discharge lamp not only can solve the heat dissipation problem of electric ballast well, and can significantly improve the service life of electric ballast.

Task of the present utility model realizes by this way: the high-intensity gas discharge lamp that a kind of electric ballast is built-in, comprise lamp housing, bulb, lamppost and electric ballast, it is characterized in that electric ballast is placed on one of them plane in lamp housing or the lamppost with an one plane, and tighten together with securing member.

An important feature of the technical program is to allow electric ballast and lamp housing or lamppost realize plane contact, by contact plane the heat that electric ballast produced is taken away and is solved heat dissipation problem.As everyone knows, metal is good heat conductor, especially with aluminium alloy or golden lamp housing and the lamppost of making of aluminium zinc, its thermal conductivity factor height, it is much bigger to add its volume ratio electric ballast, can absorb many heats, contact with air by outer surface again heat is distributed to the space, make electric ballast constant in certain temperature range.Through evidence, after the employing the technical program, the temperature of electric ballast can sharply not raise when work, and still remains in the acceptable temperature range of electric ballast in long-time, thereby has solved the heat dissipation problem of electric ballast effectively.In addition, electric ballast is placed in lamp housing or the lamppost infringement of no longer being exposed to the sun and rain, guaranteed the stability of work, prolonged service life, the inductance type ballast that makes the low electric ballast of energy consumption can replace high energy consumption is applicable, and has saved electric energy widely.

Fig. 2 is along the broken section enlarged drawing of A-A line among Fig. 1.

Fig. 3 is the structural representation of the another kind of embodiment of the utility model.

The specific embodiment

Referring to Fig. 1 to Fig. 3, the high-intensity gas discharge lamp that a kind of electric ballast is built-in comprises lamp housing 1, fluorescent tube 2, lamppost 3 and electric ballast 4.Electric ballast 4 of the present utility model is to be placed in the lamp housing 1 or on one of them plane in the lamppost 3, to tighten together by bolt 5 and nut 6 then with the one plane.Confirm that after enforcement electric ballast 4 preferably is placed in the lamp housing 1, can directly utilize inner plane supporting electric ballast 4 (see figure 1)s of lamp housing 1 rear wall 7.If be arranged on the lamppost 3, then being placed on the flat board 9 that is used for installation insurance silk and other element in the lamppost 3 bottom lamppost doors 8 is good (see figure 3).

When implementing, can on electric ballast 4 and lamp housing 1 or lamppost 3 contact-making surfaces, a thermal conductive material layer 10 be set, with further raising thermal conductivity, accelerate radiating rate.This thermal conductive material layer 10 can be a heat conduction silicone oil, can also be heat conductive rubber.

The described securing member of the technical program can be screw and nut, the securing member that rivet and key cooperate with groove.
