Embodiment Construction

[0011] figure 1 A compact fluorescent lamp 1 with a discharge vessel 9 and a housing 27 is shown. The case 27 includes the case 3 and the cover 19 . The housing 3 and the cover 19 are fixed to each other on their periphery. The discharge vessel 9 comprises three U-shaped tubes whose ends 21 bridge each other so that a continuous path of the discharge arc is formed. The discharge vessel 9 is filled with inert gas and mercury, and the U-shaped tube is sealed at the end 21 . The end 21 of the U-shaped tube extends into the interior of the housing 27 through an opening 23 in the upper part of the cover 19 of the housing 27 and is firmly fixed therein. One end of the U-shaped tube is equipped with a pin 17 communicating with the discharge tube 9 . The amalgam ball 5 is housed in the pin 17 and extends down to the bottom of the housing 3 . The amalgam ball 5 is placed at the lower end of the pin 17.

Abstract

A compact fluorescent lamp (1) comprises a plastic housing (27). The plastic housing (27) includes a plastic cap (19) and a plastic shell (3). A discharge tube (9) extends from the plastic housing (27) through openings (23) formed in the plastic cap (19). The compact fluorescent lamp (1) further comprises a tubulation (17) which contains amalgam material and communicates with the discharge tube (9). A heat conducting means is integrally formed with the plastic housing (27) which is suitable for receiving a heat conductive material (15) forming a thermal bridge towards the tubulation (17).

Description

technical field [0001] The present invention relates to a compact fluorescent lamp having a housing structure, and more particularly to a structure capable of discharging excess heat from a discharge tube of the compact fluorescent lamp. Background technique [0002] Mercury-containing single-ended low-pressure discharge lamps, commonly known as compact fluorescent lamps, are widely used for both indoor and outdoor lighting. The advantages of these light sources are their long service life and low energy consumption, which makes them economical compared to other conventional light sources. However, the light output of these lamps is largely dependent on the partial pressure of mercury, which in turn is influenced by the temperature of the discharge space. Due to the high ambient temperature, the discharge space may overheat, causing the partial pressure of mercury to exceed the optimum value. Therefore, the luminous flux of the lamp will be lower than that produced in the ...
