Description

Car light-guiding structure

Technical Field

The utility model relates to an automobile lamp especially relates to a light-directing structure in car light.

Background

The automobile lamp is an important component of an automobile and mainly comprises a lamp housing mounted on the automobile, a reflector mounted on the inner wall of the lamp housing, a light source (bulb) mounted at the inner end of the lamp housing and the reflector, and the like. The traditional light source is a halogen lamp, and light emitted by the traditional light source passes through a glass lamp tube and is scattered to the periphery, and then is emitted out of the outside after passing through a reflector to form illumination. In order to improve the brightness and prolong the service life, the halogen lamps are widely replaced by LED lamps at present, and the LED lamps mainly comprise a substrate, light-emitting diodes (lamp beads) arranged on the outer wall of the substrate, and a heat sink assembly arranged at one end of the substrate; because the light emitted by the light emitting diode is limited by an angle, a dark area which cannot be irradiated by the LED lamp exists in the reflector, and finally, the illumination of the car lamp also has a dark area, which is not beneficial to driving illumination and driving safety; meanwhile, the mounting position of the light source is generally set at the focus of the reflector, and in the LED lamp, the substrate is set at the focus position, and the light emitting diode on the sidewall of the substrate deviates from the focus by a certain distance, so that the emitted light cannot be accurately matched with the reflector, and the lighting effect of the car lamp is finally affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an there is not car light guide structure who shines the dark space to improve the illuminating effect of car light.

The utility model relates to a car lamp light guide structure, which comprises a base fixedly arranged, a luminous light source, a light guide column capable of guiding light and a light guide cover capable of scattering light to the periphery; the light guide cover is sleeved at one end of the light guide column, which emits light, and is fixedly arranged on the base.

In the light guide structure of the car lamp, one end of the light guide column and the light source are both arranged on the base, and the other end of the light guide column is sleeved with the light guide cover; light that the light source sent gets into inside the light guide post from the one end that the light guide post was installed in the base, then along the other end of light guide post directive light guide post, follow the light guide post and jet out the back to the one end of base and get into the light guide cover, the light guide cover overlaps in the light guide post tip, its axis and the coincidence of the axis of light guide post, and the light guide cover can radially derive light to make light jet out from the light guide cover and scatter all around, after that again cooperate with the speculum of car light and form required illumination effect.

Detailed Description

A car light guiding structure comprises a base 1 which is fixedly installed, a light source 2 which can emit light, a light guiding column 3 which can guide the light and a light guiding cover 4 which can scatter the light to the periphery; the light guide cover is sleeved at one end of the light guide column, which emits light, and is fixedly arranged on the base.

Car light guide structure, light source 2 fixed mounting is in the one end that leaded light post 3 is located base 1 to make light inject into the leaded light post more accurately, also be favorable to reducing the loss of light energy, and it is required to reduce the power of light source.

Car light guide structure, the lateral wall of leaded light post 3 is provided with the reflector layer of light that can reflect, this can make light follow one end wherein to the other end to reduce the loss of light energy, and concentrate and jet out from the one end of leaded light post dorsad base, thereby more accurately with the speculum cooperation of car light, guarantee the illumination effect. In addition, the end of the light guide column 3 back to the base 1 is conical, so that more light rays are emitted to the outward area of the reflector, the inner end of the reflector, which is emitted by the light rays, is reduced, the light rays are emitted out of the vehicle lamp more intensively, and the illumination brightness is improved.

In the car light guide structure, the light guide cover 4 is columnar and is sleeved at the end part of the light guide column 3 along the axis direction, so that light rays can be emitted more accurately along the periphery; the light guide cover 4 can be a divergent tube for changing light angle and scattering, or a fluorescent tube with a tube wall or fluorescent powder arranged inside, so as to match the use requirements of different light sources.

Car light guide structure, light guide cover 4 includes two shading shells 41 that set up relatively to and set up the light pipe 42 that can see through light between two shading shells, the tip of leaded light post 3 passes one of them shading shell and the one end of light pipe and extends to in the light pipe, the both ends of light pipe overlap in the shading shell, interval between two shading shells is unanimous with traditional tungsten filament lamp, can make the illumination scope more be close to traditional car light. In addition, in the car lamp light guide structure, the positioning column is arranged at one end of the light guide cover 4 back to the light guide column 3 and is fixedly connected with the light guide cover so as to be used for fixing the light guide cover, improve the structural strength of the car lamp and prevent light rays from penetrating through the light guide cover; meanwhile, the positioning column 5 may also be a light guide element connected with another light source and capable of guiding light, and the end of the positioning column passes through the end of the light guide cover 4 and extends into the light guide cover, so that the light intensity is increased by a mode of light transmission at two ends.

As shown in fig. 1 and 2, one end of the light guide column and the light source are both installed on the base, and the other end of the light guide column is sleeved with the light guide cover; light that the light source sent gets into inside the light guide post from the one end that the light guide post was installed in the base, then along the other end of light guide post directive light guide post, follow the light guide post and jet out the back to the one end of base and get into the light guide cover, the light guide cover overlaps in the light guide post tip, its axis and the coincidence of the axis of light guide post, and the light guide cover can radially derive light to make light jet out from the light guide cover and scatter all around, after that again cooperate with the speculum of car light and form required illumination effect. According to the light guide structure of the car lamp, the light source is arranged on the base, so that the connection with a circuit is facilitated, the installation convenience is improved, and the light guide structure can be directly connected with the heat dissipation assembly on the base, so that the heat dissipation efficiency is improved; after light rays emitted by the light source are subjected to light guide action of the light guide column and the light guide cover, an illumination range similar to that of a traditional halogen lamp can be formed, so that dark areas are eliminated, the illumination range of the car lamp is ensured, and the driving safety is improved; simultaneously, leaded light post and light guide cover all set up on the axis of car light to can accurately set up the light guide cover in the focus position of speculum, thereby make the accurate cooperation of light and speculum, in order to improve the illumination effect, and also can make it be applicable to all kinds of car lights through this kind of mode of setting, greatly improved application scope.
