Description

Technical Field

[0001] The utility model relates to the technology in the field of lighting. The main technology is to provide a tail lamp device with a reflector, which is used to reflect lights in different directions and can simultaneously meet the tail lamp lighting device standards of Europe. Background Art

[0002] Compared with daytime, due to the lack of light when riding a bicycle at night, lighting equipment is a very important configuration to facilitate clearly observing the road conditions at night. Therefore, even if a bicycle is not equipped with a headlight when leaving the factory, the rider will also install a headlight and a tail lamp by himself for the safety of night driving.

[0003] Especially in the selection of the tail lamp, there are unique requirements. Because the daytime lamp can be not irradiated due to daytime and is mainly used for irradiating the front, while the tail lamp is different. The tail lamp must be equipped both in the day and at night. In order to increase the safety of riding a bicycle, usually a reflector is installed beside the tail lamp. In this way, as long as there are lights from other different angles irradiating on the reflector, it will be reflected for other drivers to see and remind the driver of the existence of a bicycle rider at the reflector light source.

[0004] However, since there is not much extra space on the tail side of the bicycle lamp, if the tail lamp and the reflector are installed at the same time, not only the cost will increase, but also a large area will be occupied, which is not conducive to the requirements of speed or weight during riding. Therefore, some manufacturers have created a tail lamp device with a reflector that combines a tail lamp and a reflective lens.

[0005] As Figure 8 and Figure 9 shown, since the lamp body 81 of the existing tail lamp 80 is arranged inside and is covered by the external reflective lens 82 (most of this kind of reflective lens is mainly implemented by a cylindrical lens), it cannot directly emit light outside the tail lamp 80 for illumination, but must be reflected by the reflective lens 82 before it can be emitted. And due to the characteristics of the reflective lens 82, the light emitted by the illuminating lamp body 81 will be reflected randomly, resulting in the direct illumination brightness of this kind of tail lamp 80 often being insufficient.

[0006] When the tail lamp 80 is irradiated by other drivers from different directions, there will be a warning effect due to the light reflection of the reflective lens 82, but the direct light of it must also have a certain value. Otherwise, ignoring the direct light in order to take into account different directions is not what the industry needs. Moreover, mainstream and authoritative specifications (such as K-mark (German standard), E-mark (European standard)) have the brightness values of the emitted light that should be achieved at different angles, which shows that the tail lamp 80 has a very important function.

[0007] However, in common practice, the brightness value of the light emitting lamp body 81 is changed to expand the brightness value in the straight-line emission direction. However, changing the light emitting lamp body 81 is nothing more than increasing the volume and current, which will cause problems of being too large and too heavy, which not only increases the cost but also is not suitable for industry use.

[0008] In addition, some relevant industries have deliberately replaced the original reflecting lens 82 with a transparent lens at the position relative to the reflecting lens 82 and the light-emitting lamp body 81 to increase the brightness of the light emitted in a straight line. However, this approach still causes the brightness of the light emitted at 110 degrees on both sides to be insufficient, which does not comply with relevant regulations.

[0009] In view of the above content, it can be known that how to break through the current bicycle taillights that are limited by the structural device of the taillight 80 with a reflective lens 82 as a whole, and it is difficult to produce a taillight 80 that not only meets the specified direction brightness value, but also must meet the expected volume size structure. This is an urgent problem that needs to be solved in the current industry. Therefore, relevant lighting companies must think about the lighting problems of existing lamps and how to solve them to meet the needs of public use. Utility Model Content

[0010] The main purpose of the present invention is to reflect lights from different directions and meet European standards at the same time, which improves the shortcomings of the prior art. In order to achieve the above-mentioned effects and improve the shortcomings of the prior art, the present invention is a taillight device with a reflector, which includes: a base, the base is provided with a receiving portion for accommodating related components, and the base is provided with a fixing hole for the fixing assembly to be fixed to the receiving portion of the base after passing through the related components;

[0011] A light-emitting member, which has a combination hole at a position relative to the fixing hole of the base and has a light-emitting body disposed thereon;

[0012] A light guide, which is a hollow annular light guide, and can guide the light emitted by the light emitting body of the light emitting element, and make the light be scattered outward through the light guide of the annular light guide, and can meet the regulations of relevant countries;

[0013] A light shielding member, which is arranged in accordance with the shape of the hollow portion of the light guide, and is a light-proof component, and is provided with a corresponding snap-fit block for being snapped into the hollow portion of the light guide; and

[0014] A reflector, the shape of which is designed relative to the accommodating part of the base. In this way, when the light-shielding part is buckled into the hollow part of the light guide body, the light-shielding part, the light guide body and the light-emitting part can be simultaneously buckled into the accommodating part of the base. A columnar reflecting mirror is formed in the reflector to facilitate reflection when light from all external directions enters, and the light emitted by the light-emitting part can also be guided into the reflector through the light guide of the annular light guide part of the light guide body.

[0025] In order to clearly illustrate the above-mentioned objects and effects that the present utility model can achieve, the features and effects of the embodiments of the present utility model will be described in detail with reference to the drawings. Please view with the drawings as Figures 1 to 5As shown in FIG. 1 , the utility model is a tail light device 20 with a reflector, which includes: a base 30, the base 30 is provided with a receiving portion 31, and the base 30 is provided with a fixing hole 32 for being mounted on the dirt bike of the bicycle by using another fixing assembly 33 (see FIG. 1 ). Figure 5 shown).

[0026] A light emitting member 40 is installed in the receiving portion 31 of the base 30. The light emitting member 40 has a combination hole 41 corresponding to the fixing hole 32, and a light emitting body 42 (a COB LED lamp device is used as an example in the figure) is provided at the other end of the light emitting member 40 opposite to the combination hole 41 as a light source.

[0027] A light guide 50 is installed in the receiving portion 31 of the base 30 and stacked on the light emitting element 40. The light guide 50 further includes a hollow portion 51 and an annular light guide portion 52. The light emitted by the light emitting body 42 of the light emitting element 40 can be guided out through the annular light guide portion 52, and the light can be guided by the annular light guide portion 52 and dispersed laterally outward, so as to comply with the regulations of relevant countries.

[0028] In this way, the ribs protruding around the fixing holes 32 of the base 30 can be used to allow the light-emitting element 40 to be assembled on the outer periphery of the ribs and fixed in the receiving portion 31 with the combination holes 41. The light guide 50 is then assembled in the receiving portion 31 after the light-emitting element 40 is assembled. In addition, before the embodiment is installed on the soil remover, the fixing assembly 33 has already been installed on the base 30. A part of the fixing assembly 33 passes through the base 30 and is combined with the soil remover, and a part of the fixing assembly 33 is stuck in the fixing holes 32, thereby firmly combining with the soil remover, which is best shown in Figure 3 As shown.

[0029] A shading member 60 is arranged in the shape of the hollow portion 51 in the light guide 50, and the shading member 60 is a light-proof component, and a snap-fit block 61 is provided on one side of the shading member 60. The shading member 60 is assembled in the hollow portion 51, and the snap-fit block 61 is snap-fitted with the light guide 50 to be assembled.

[0030] A reflective plate 70 covers the base 30. The shape of the reflective plate 70 is set relative to the accommodating portion 31 of the base 30. In this way, when the shading member 60 is buckled into the hollow portion 51 of the light guide 50, the shading member 60, the light guide 50, and the light-emitting member 40 can be buckled into the accommodating portion 31 of the base 30 at the same time. A cylindrical reflector 71 is formed on the side of the reflective plate 70 facing the shading member 60 to facilitate reflection when external light from various directions comes in, and the light emitted by the light emitting body 42 of the light-emitting member 40 can also be dispersed outward through the light guiding of the annular light guiding portion 52 of the light guide 50.

[0031] According to the foregoing description, the taillight device 20 with a reflector of the present utility model mainly combines the light-emitting element 40, the light guide 50, the light-shielding member 60 and the reflector 70 in the accommodating portion 31 of the base 30. Thus, when the light-emitting body 42 of the light-emitting element 40 emits light, due to the light-blocking effect of the light-shielding member 60, all the light will completely enter the annular light guide portion 52 of the light guide 51 and enter the reflector 70 through the annular light guide portion 52. In this way, the light entering the reflector 70 can be evenly dispersed to the ring side by the arrangement of the columnar reflector 71, and the light brightness in the middle can also reach the specified standard.

[0032] In a better embodiment of the present utility model, columnar light guide portions 53 are provided at the middle positions on both sides of the annular light guide portion 52 of the light guide 50 (please see Figure 6 and Figure 7 shown). Thus, when the light-emitting body 42 of the light-emitting element 40 emits light, when the light completely enters the annular light guide portion 52 of the light guide 51, through the columnar light guide portions 53 provided at the middle positions on both sides of the annular light guide portion 52, the light entering the reflector 70 can be refracted more towards the middle by the arrangement of the columnar reflector 71, and the light brightness in the middle can better reach the specified standard. Obviously, the present utility model is more in line with the use of the general public than the prior art and has more substantial progressiveness and practicality.
