Floodlight reflector, floodlight and powerboat

Abstract

The invention provides a floodlight reflector, a floodlight and a powerboat, which are applicable to the field of lighting. The inner surface of the reflector is formed by a line segment rotating around an axis line, and the line segment is formed by connecting a plurality of segments sequentially; the projected length of each segment in the axis line is 0.6-7.8 mm; the included angle of the extension line of the line segment and the axis line is 8-40 degrees; and the axis line is coincided with the optical axis of a light source. In the embodiment, the inner surface of the floodlight reflector is formed by the rotation of the line segment, a small part of light rays sent by the light source are emitted directly, and most part of light rays are reflected by the reflector and then are emitted in a crossed way; the luminescence angle of the floodlight is 20+ / -2 degrees; the uniformity degree of the inner illumination intensity of the luminescence angle is extremely high, which can meet the light distribution requirement of the floodlight; and the size of the reflector can be reduced greatly so that the sizes of the floodlight and an LED light made from the reflector are also small. The invention is suitable for occasions with a strict requirement for the sizes of lights, and particularly can be used as a roof light and a ceiling light of a powerboat.

Description

technical field [0001] The invention belongs to the field of lighting, and in particular relates to a floodlight reflector, a floodlight and a motor boat. Background technique [0002] Existing office lighting generally adopts fluorescent lamps, which can obtain better uniformity of illumination, but consume a lot of power, have a short service life of lamps, and are prone to breakage and other dangers. In addition, fluorescent lamps are large in size and poor in anti-vibration performance, so there are certain limitations in installing them on the roof of the cabin. [0003] As an energy-saving and reliable light source, LED has been widely used in the field of lighting, gradually replacing fluorescent lamps and other non-LED light sources. At present, floodlights using LEDs as light sources generally use reflectors for light distribution. There is a reflector whose inner surface is conical, such as Figure 1a and Figure 1b shown. The depth of the reflector is greater ...
