Problems solved by technology

[0005] In summary, the disadvantages of the prior art mentioned above generally include that due to the light distribution and power distribution requirements of the existing car lights, most of the light-emitting modules are installed between the lampshade and the battery room, and because the car light shell is closed, the air cannot flow to dissipate heat. , leading to the disadvantage that the light-emitting diodes are prone to epitaxy light decay or even damage due to overheating

Embodiment Construction

[0024] In order to illustrate the central idea of ​​the present invention in the column of the above-mentioned summary of the invention, it is expressed in specific embodiments. Various objects in the embodiments are drawn in proportions suitable for illustration rather than in proportion to actual components, and are described first.

[0025] Such as Figure 1~Figure 3 As shown, the present invention is a bicycle light with a light pipe structure, which mainly includes:

[0026] A car lamp housing 10 has a battery chamber 11 inside it for installing power sources such as accumulators for power supply. Wherein, the front end of the car lamp housing 10 has an accommodating space 12, and the accommodating space 12 forms an opening 13 at one end of the car lamp housing 10;

[0027] A reflector 20 is disposed in the accommodating space 12, and the reflector 20 is provided with a reflective surface 21 away from the opening 13, and a light-emitting surface 22 adjacent to the openi...

Abstract

The invention provides a bicycle lamp with a light pipe structure. The bicycle lamp mainly comprises a lamp shell, a reflector, at least one light emitting element and at least one light pipe; a battery compartment is arranged inside the lamp shell, and accommodating space is arranged at the front end of the lamp shell; the reflector is arranged in the accommodating space; the light emitting elements are arranged in the lamp shell; each light pipe comprises an incident end and an emergent end, the incident ends face the light emitting elements, and the emergent ends face the reflector. The bicycle lamp has the advantage that light emitted by the light emitting elements can be transmitted to the reflector via the light pipes, is reflected by the reflector and then is projected out of the bicycle lamp.

Description

technical field [0001] The invention relates to a lighting fixture, especially a bicycle lamp with a light guide tube structure which is convenient for arranging the internal structure of the lamp to achieve good heat dissipation effect. Background technique [0002] Generally, the existing bicycle lamps mostly comprise a lamp housing, and a lampshade, a light-emitting module and a battery chamber for providing power are sequentially assembled inside the lamp housing. Moreover, because light-emitting diodes have the advantages of low power consumption, long life, fast response, small size and high brightness, a large number of light-emitting diodes (LEDs) are used as light-emitting elements in light-emitting modules. [0003] For the existing light-emitting diode (LED) efficiency level, 70%~80% of the input electric energy is converted into heat that cannot be released by radiation, and the size of the light-emitting diode is small, and the heat is easy to accumulate at the ...
