Embodiment Construction

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0018] In the embodiment of the present invention, the inner surface of the spotlight reflector is designed as a paraboloid with a focal length of 2.4-2.6mm, and the focal point of the paraboloid is the luminous point of the light source, so that the optical axis of the light source coincides with the central axis of the reflector, and the light emitted by the light source is reflected The light spot formed by the parallel output after the reflector is uniform, the luminous angle is small, the light efficiency is high, and the light gathering effect is good.

Abstract

The invention is suitable for the field of lighting, and provides a spot lamp reflector, a spot lamp and a head lamp. The inner surface of the spot lamp reflector is of a paraboloid; the focal length of the paraboloid is between 2.4 and 2.6 mm; the focal point of the paraboloid is a luminous point of a light source; and the optical axis of the light source is overlapped with the central axis of a reflector. The inner surface of the spot lamp reflector is designed as the paraboloid of which the focal length is between 2.4 and 2.6mm; the focal point of the paraboloid is the luminous point of the light source; the optical axis of the light source is overlapped with the central axis of the reflector; and light spots formed by the light which is emitted from the light source and is emitted in parallel after being reflected by the reflector have the characteristics of uniformity, small radiant angle and perfect spotlight effect, so the spot lamp reflector can particularly serve as the reflector of the head lamp.

Description

Technical field [0001] The invention belongs to the field of lighting, and particularly relates to a spotlight reflector, a spotlight and a headlight. Background technique [0002] Existing headlights generally use bulbs as light sources, which have low cost, but have high power consumption, short battery life, and risk of being easily broken. In addition, the existing headlamps are large in size and poor in anti-vibration performance, and mining personnel carry them, which has certain limitations. [0003] As an energy-saving and reliable light source, LED has been widely used in the lighting field, gradually replacing light bulbs and other non-LED light sources. Such as figure 1 As shown, after the light emitted by the LED light source is reflected by the existing spotlight reflector, the spot is not uniform enough, and the light gathering effect is poor. Summary of the invention [0004] The purpose of the embodiments of the present invention is to provide a spotlight reflector...
