Embodiment Construction

[0023] refer to figure 1 , a structural schematic diagram of the first embodiment of the fluorescent lamp of the present invention, the fluorescent lamp includes a laser light source 110, a fluorescence generating element 120, and a coupling lens 130 arranged in sequence; The second color light is generated under the excitation of the first color light; the coupling lens 130 is used to focus and shape the first color light and the second color light to form a third color light and output it.

[0024] Such as figure 1 As shown, the black arrow indicates the first color light, the white arrow without tail indicates the second color light, and the white arrow with tail indicates the third color light.

[0025] Wherein, the laser light source 110 is generally a multi-point surface array laser light source, so that the first color light can be incident on the fluorescence generating element 120 at multiple points. The incident surface of the generating element 120 is incident at ...

Abstract

The invention discloses a fluorescent lamp which comprises a laser light source, a fluorescence generating element and a coupling lens which are sequentially arranged. The fluorescence generating element is used for generating second colored light under the motivation of first colored light emitted by the light source, and the coupling lens is used for performing focus shaping on the first colored light and the second colored light to form third colored light and outputting the third colored light. In this way, the fluorescent lamp can improve the transformation efficiency of the light source and reduce the emitting angle, and has a good light beam effect.

Description

technical field [0001] The invention relates to the lighting field, in particular to a fluorescent lamp. Background technique [0002] Fluorescence is a kind of cold luminescence phenomenon of photoluminescence. When a substance at room temperature is irradiated by incident light of a certain wavelength (usually ultraviolet or X-ray), it absorbs light energy and enters an excited state, and immediately de-excites and emits outgoing light with a wavelength longer than that of the incident light (usually at a wavelength of Visible light band); and once the incident light is stopped, the luminescent phenomenon will disappear immediately. The outgoing light with this property is called fluorescence. [0003] The existing white light LED solution is to use blue light LED to directly transmit to the phosphor matrix to obtain long-wavelength yellow light, and the yellow light generated by excitation and the remaining blue light are mixed according to a certain color matching rati...
