Description of the Invention: [Technical Field of the Invention] The present invention relates to a light source module and a lamp. [Prior Art] With the advancement of semiconductor technology, the power that can be achieved by a light-emitting diode (LED) is increasing, and the intensity of light emitted is getting higher and higher. In addition, the light-emitting diode has the advantages of power saving, long service life, environmental protection, fast startup, small size, and the like. Therefore, the light-emitting diodes are also widely used in lighting equipment, traffic signs, displays, optical mice, etc., and there is a tendency to gradually replace the conventional fluorescent tubes. For the conventional small white light emitting diode lighting fixtures, the following two problems generally exist. First of all, the optical design space of small luminaires is limited. It is difficult to deflect the large deflection angle light emitted by the illuminating diode into a light with a sufficiently small deflection angle by conventional optical design methods. In the case of lighting fixtures, it is stray light, which has a influence on the final light pattern and the angle of illumination. Furthermore, the reason why the white light emitting diode emits white light is because the light emitting diode (9) emits blue light, blue light, and the fluorescent light gives the woman a yellow light, while the yellow light and the t-converted blue light are used by the county powder. That is, it is mixed into light. Due to the degree of directivity emitted by the light-emitting diodes, this results in a weaker intensity of the light from the larger angles, which in turn makes the degree of deviation from the optical axis larger than the intensity of the blue light. In this way, it will cause the edge of the ',? , 201131110 EL98018 31362tw£doc/n ” " In addition, the general light of the light-emitting diode lamps _ the way of the two ends of the line, so the design of the line will make multiple lamps benefit, extend The direction of the invention is arranged in a close-fitting manner in a straight line. [Invention] The present invention provides a light source module having a small light exit angle. The present invention provides a light fixture having a small light exit angle.
