Abstract

The invention discloses an electromagnetic induction lamp capable of controlling the temperature of a cold end. The electromagnetic induction lamp comprises a blister (108). At least one continuous or a plurality of scattered sinking troughs (103) with sunken outside and protruded inside are formed from the outer contour surface to inner contour surface of the blister (108). A fluorescent powder layer is coated on the inner contour surface of the blister (108), and receives ultraviolet rays radiated by mercury atoms in the blister (108), thereby forming visible light radiation. The electromagnetic induction lamp capable of controlling the temperature of the cold end has relatively higher light emitting efficiency and relatively lower electric energy loss.

Description

Technical field [0001] The invention relates to the field of lighting, in particular to an electromagnetic induction lamp capable of controlling the temperature of the cold end. Background technique [0002] High-brightness output fluorescent lamps and metal halide discharge arc lamps can provide effective high lumen output and good color reproduction. Among them, the high-brightness fluorescent lamp is based on the conventional electrode fluorescent lamp technology. In order to make the electrodes have a longer life, the pressure of the buffer gas in these lamps is about 400Pa, and the discharge current is generally less than 1.5A. The requirements for long life and efficiency limit the working range of these lamps, mainly limiting the maximum axial brightness that these lamps can effectively produce. Therefore, for the luminous flux they can generate, fluorescent lamps are only at a moderate level, typically not exceeding 85lm / W. It is widely used in various indoor lighting ...
