Reflection cup and bicycle lamp with same

Abstract

The invention discloses a reflection cup which comprises a cup body. The cup body comprises a first opening allowing a light source to penetrate and located at the rear end and a second opening allowing light rays to emit, the contour line of the second opening gradually extends from the middle or the lower portion of the front end of the cup body towards two sides in the direction of the rear end of the cup body and is in bending transmission towards the middle at the position close to the first opening to form a smooth closed curve, and therefore gaps allowing light rays to emit downwards are formed in at least a part of the lower portion of the cup body. The invention further discloses a bicycle lamp with the reflection cup. At least a part of the lower portion of the reflection cup is set to be of a structure with missing parts (the gaps allowing the light rays to emit downwards), so that light emitted by the light source can guarantee far illumination and can also guarantee near illumination after passing through the reflection cup, namely the light can illuminate a far position and can also illuminate a near position. When the reflection cup is applied to the bicycle lamp, the ground and other things before a front tire of a bicycle can be illuminated, so that a user can know the environment at the far position and the environment at the near position, and therefore the safety of the user while the user rides the bicycle at night is guaranteed.

Description

technical field [0001] The invention relates to a lighting device, in particular to a reflective cup used in the lighting device and a bicycle light with the reflective cup. Background technique [0002] Bicycle lights are lamps installed on bicycles for night riding, so that users can also install them in front of bicycles in environments where the light is insufficient at night and the lighting conditions cannot meet safe riding conditions (street lights are not bright enough or there are no street lights). Better visual conditions can be obtained by using the internal lamps. In order to obtain better floodlight and long-range effects, the current common practice is to install a reflector around the light source of the bicycle light. The commonly used reflector is cup-shaped, commonly known as a reflector cup. The light emitted by the light source is reflected The inner surface of the cup is reflected and then emitted, which produces a concentrating effect on the light em...

[0004] However, see figure 1 , similar to that disclosed in the above-mentioned patent, since the reflective surface of the existing reflective cup 12' is a complete cup shape, after reflecting the light emitted by the light source, the light can only be gathered to meet the long-range requirements of the outgoing light, that is, it can However, for places that are relatively close to the bicycle, such as the ground in front of the front tire of the bicycle, effective lighting cannot be achieved, which will lead to the lack of clarity of the nearby ground when the bicycle is riding. There is an accident due to the situation, and there is no small safety hazard
