Flood light reflector, flood light and motor boat

Abstract

The invention is suitable for the lighting field and provides a flood light reflector, a flood light and a motor boat. The inner surface of the reflector is formed by rotating a fold line section around an axle line, and the fold line section is formed by sequentially connecting a plurality of line sections; each line section has a projected length of 0.6-4.5mm on the axle line, and the extended line of the fold line section has an included angle of 0-40 degrees with the axle line; and the axle line and the optical shaft of a light source coincide. In the embodiment of the invention, the fold line section is rotated to form the inner surface of the flood light reflector, a minor part of light rays emitted by the light source directly emerge out, and the major part emerges out in a crossing way after being reflected by the reflector; a light-emitting angle of the flood light is 40+ / -2 degrees, and the illuminance uniformity inside the light-emitting angle is extremely high and meets the light distribution requirements of the flood light; and moreover, the size of the reflector can be greatly reduced, and the flood light and the LED lamps made by the reflector also have small sizes, are suitable for occasions having strict requirements on the sizes of the lamps and particularly can be used as the dome light or the ceiling light of the motor boat.

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 ...
