Embodiment Construction

[0022] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, the same or similar parts are denoted by the same or similar reference numerals. In order to avoid obscuring the gist of the present invention due to unnecessary details, only structures and components closely related to the solutions of the present invention are shown in the drawings, while other details that are not relevant are omitted.

[0023] image 3 is a perspective view showing a heat dissipation cover 300 according to an embodiment of the present invention. The heat dissipation cover 300 is used to be disposed between the discharge tube and the lamp holder of the reflection type / shielded compact fluorescent lamp to isolate the discharge tube and the lamp holder, and the heat dissipation cover 300 is fixed to the lamp holder through the fixing part. In this embodiment, the heat dissipation cover 300 has a flange 310 as a fixing ...

Abstract

The invention discloses a reflective / covered compact fluorescent lamp with a radiating cover, which comprises the radiating cover and a fixing part, wherein the radiating cover is arranged between a lamp holder and a discharge tube; the fixing part is used for coupling the radiating cover to the lamp holder; the radiating cover is made from a nonvolatile material; and a clearance is formed between a part, isolating the discharge tube from the lamp holder, of the radiating cover, and the lamp holder.

Description

technical field [0001] The present invention relates to a reflection type / shade compact fluorescent lamp (CFLi), in particular to a reflection type / shade compact fluorescent lamp with a heat dissipation cover between a lamp holder and a discharge tube. Background technique [0002] Currently, traditional incandescent lamps with tungsten filaments are being replaced by compact fluorescent lamps, which are more energy efficient, last longer and have higher luminous efficiency. Compact fluorescent lamps often need to be installed in lighting fixtures or housed in reflectors or lampshades to obtain a more even diffused light output and to make them appear closer to incandescent lamps. While the energy efficiency of discharge lamps has improved, they have also created new challenges in terms of design. With the burner sealed inside the reflector / lamp housing, the operating temperature will rise by 30°C to 50°C. Elevated temperatures will result in poor lumen maintenance due to ...
