Abstract

The utility model relates to an electronic transformer for quartz lamps. The electronic transformer for quartz lamps is composed of an electronic transformer and an outer shell, wherein, the outer shell is composed of a metallic outer shell and a nonmetallic outer shell. A switch transistor is tightly fixed on the wall of the metallic outer shell. The structure is adopted by the utility model, so the temperature inside a die cavity of the working electronic transformer can be rapidly emitted, the temperature of the switch transistor is reduced, the working reliability of the switch transistor is improved, and the safety and the lifetime of the electronic transformer for quartz lamps are ensured.

Description

Electronic transformer for quartz lamp

A kind of quartz lamp electronic transformer relates to the shell of quartz lamp electronic transformer and the improvement of structure.

Modern age, light source such as quartz lamp light beam were concentrated, and were that shot-light, ceiling light, the track lamp demand of light source is very big by quartz lamp, and therefore the quartz lamp electronic transformer of being made up of electronic device is also little, in light weight and obtain numerous clients' favor with its volume.But because for making electronic transformer safety and dustproof, easily make again, used electronic transformer adopts nonmetallic materials to make enclosed construction more, like this, in the big place of change in voltage (as China various places, sooner or later voltage difference is big) when using, triode causes that acutely the phenomenon that electronic transformer burns is very serious because the variation of voltage changes the pipe temperature rise, brings great influence for the use popularization of electronic transformer.

The purpose of this utility model is to provide a kind of follow-on quartz lamp electronic transformer, the radiator of metal material as the electronic transformer switch triode adopted in utilization on Electronic transformer shell, thereby reduce temperature in the electronic transformer die cavity that causes because of the triode heating, improve the functional reliability of triode, guarantee the safe in utilization of quartz lamp electronic transformer.

The utility model is to implement like this: in the quartz lamp electronic transformer of being made up of shell and electronic transformer, the shell 1 that employing is formed by nonmetallic materials compactings and form the shell of electronic transformer by the shell 2 that the metal material punching out forms is fixed on the 7 usefulness insulating material of the switch triode in the transformer and securing member on the metal shell simultaneously and forms.

Below, structure of the present utility model is described in detail in detail in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of quartz lamp electronic transformer.

As shown in the figure, the said quartz lamp electronic transformer of the utility model is made up of shell and the electronic transformer 4 that is contained on the wiring board 3, wherein, shell 1 is formed by the shell 1 that adopts nonmetallic materials (as flame retardant plastics or flame-retardant phenolic resin) compacting to form with by the shell 2 that the metal material punching out forms, the electronic transformer 4 usefulness securing member 10a, the 10b that are contained on the wiring board 3 are fixed on the non-metal shell 1, and two switch triodes 7 on the electronic transformer 4 are fastened on the metal shell 2 with terylen pad 6, screw 5, nut 8, compressing tablet 9 respectively.

Adopted the quartz lamp electronic transformer of the said structure of the utility model, because the radiator of the sheet metal of equivalent area as switch triode 7 arranged, both can reduce the temperature of the triode body that causes greatly owing to the external power change in voltage rapidly, temperature in the electronic transformer die cavity can be distributed to the space again, thereby improved the functional reliability of switch triode, guaranteed the safe in utilization and life-span of quartz lamp electronic transformer.

Claims

1, a kind of quartz lamp electronic transformer, form by shell and electronic transformer, it is characterized in that shell shell (1) that is pressed into by nonmetallic materials and the shell that is become by the metal material punching out (2) form, simultaneously the switch triode (7) on the electronic transformer (4) is fastened on the wall of metal shell (2) with terylen pad (6), screw (5), nut (8) and compressing tablet (9).
