Description

Technical Field

[0001] The utility model relates to the field of automobile light bulbs, in particular to a high-light-transmittance automobile light bulb. Background Art

[0002] Automotive lighting is one of the most important and indispensable parts of a car. Its main function is to illuminate the road ahead at night or when visibility is low, provide drivers with a good view, and ensure driving safety. Traditional automotive bulbs mainly use halogen bulbs or xenon bulbs, but these bulbs have disadvantages such as yellowish light, small illumination range, and high energy consumption, which are difficult to meet the needs of modern automotive lighting.

[0003] In order to overcome the above shortcomings, various improvement schemes have been proposed in the prior art. Some schemes try to use LED light sources instead of traditional halogen light sources to improve lighting brightness and service life; other schemes use the collimation and high brightness characteristics of laser beams to achieve long-distance illumination; and some schemes focus on intelligent control, automatically adjusting the lighting angle and beam shape according to parameters such as vehicle speed and steering angle to adapt to different driving conditions.

[0004] Although the above technologies have improved the performance of automotive bulbs to a certain extent, there are still problems such as low lighting efficiency and low light utilization, which urgently need further improvement. Traditional automotive bulbs usually use a simple reflector design, which makes it difficult to effectively collect and utilize the light emitted by the filament, resulting in a large amount of light loss and poor lighting effect. In addition, the light transmittance of the lampshade material needs to be improved. The existing lampshade material has a low light transmittance, which further exacerbates the problem of light loss.

[0005] Therefore, how to further improve the light transmittance and light utilization rate of automobile bulbs to achieve high-brightness, low energy consumption, and less shadow-rich high-quality car lighting has become a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0006] In order to make up for the shortcomings of existing technologies, the problem of how to further improve the light transmittance and light utilization rate of automobile bulbs to achieve high-brightness, low energy consumption, and less shadow-rich high-quality car lighting was solved.

[0007] The technical solution adopted by the utility model to solve its technical problem is: the high-light-transmittance automobile light bulb described in the utility model includes a lampshade, a lamp wall, a lamp holder, a lamp tube, a scattering mirror, a reflector and a threaded connecting pipe. The lampshade is connected to the lamp wall through a threaded connecting pipe, and the scattering mirror and the reflector are arranged inside the lampshade. This design makes the light bulb structure compact and easy to assemble, while protecting the internal scattering mirror and reflector.

[0008] Preferably, the scattering mirror is arranged in an arc shape, and its opening faces the lamp tube. This design can better converge the light emitted by the lamp tube onto the scattering mirror, thereby improving the scattering effect.

[0009] Preferably, the reflector is arranged in a parabolic shape, and the focus is located at the center of the lamp tube. This design can efficiently converge the light emitted by the lamp tube and reflect it onto the scattering mirror, thereby reducing light loss and improving lighting efficiency.

[0010] Preferably, the lampshade is made of a material with high light transmittance, and the light transmittance is not less than 95%. This design can minimize the loss of light on the lampshade and improve the luminous efficiency and brightness of the bulb.

[0011] Preferably, both ends of the lamp tube are electrically connected to the lamp holder, and the lamp tube is located at the focus of the scattering mirror and the reflecting mirror. This design can ensure that the light emitted by the lamp tube is accurately converged and scattered, thereby improving the lighting performance of the bulb.

[0012] Preferably, the inner surface of the scattering mirror is provided with a diamond-shaped scattering structure for evenly scattering the light emitted by the lamp tube. This design can effectively reduce the local concentration of light, produce a soft and uniform lighting effect, and improve visual comfort.

[0013] The utility model is beneficial in that:

[0014] 1. Improve the light transmittance of automobile bulbs. By using high light transmittance materials to make the lampshade, the light transmittance of the lampshade is not less than 95%, which greatly reduces the loss of light on the lampshade and allows more light to pass through the lampshade and illuminate the road ahead.

[0015] 2. Enhanced the uniform scattering effect of light. The scattering mirror is set in an arc shape, and the inner surface is provided with a diamond scattering structure, which can evenly scatter the light emitted by the lamp tube in all directions, reduce the local concentration of light, and make the lighting light softer and more uniform.

[0016] 3. Efficient use of light is achieved. The reflector is set in a parabolic shape, and the focus is located at the center of the lamp tube, which can effectively converge and reflect the light emitted by the lamp tube to the front, reduce unnecessary loss of light, and improve light utilization.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment provides a high-transmittance automotive light bulb, including a lamp holder 1, a lamp tube 2, a reflector 3, a scattering mirror 4 and a lampshade 5. The lamp holder 1 is provided with a terminal 11 for connecting to the vehicle power supply. The lamp tube 2 is fixed on the lamp holder 1, and adopts a halogen filament with a power of 55W. The reflector 3 is arranged in a parabolic shape, with the focus located at the center of the lamp tube 2. The inner surface of the reflector 3 is polished and the reflectivity is not less than 95%. The scattering mirror 4 is arranged in an arc shape in front of the reflector 3. The inner surface of the scattering mirror 4 is provided with a diamond scattering structure. The side length of the diamond is 1.5mm, and the distribution density is 10 / cm 2 The lampshade 5 is made of polycarbonate material with high light transmittance, and the light transmittance is not less than 96%. The lampshade 5 and the lamp holder 1 are connected by threads.

[0024] When in use, the vehicle power is turned on, the lamp tube 2 is lit, the emitted light is converged by the reflector 3 and reflected to the scattering mirror 4, and then evenly scattered by the scattering mirror 4 through the lampshade 5 to illuminate the road ahead, achieving a high-brightness, less shadow and high-quality lighting effect.

[0025] Example 2

[0026] On the basis of Example 1, the lamp tube 2 adopts an LED light source, the luminous color is 6000K pure white light, the color rendering index is not less than 90, and the luminous flux is not less than 3000lm. A layer of anti-reflection film is further provided on the inner surface of the reflector 3 to increase the reflectivity to more than 98%. The scattering mirror 4 is changed to a double-layer structure, the inner layer is a diamond scattering structure, and the outer layer is a honeycomb scattering structure, which further improves the uniformity of scattering.

[0027] The high-transmittance automobile light bulb in Example 2 further optimizes the design of the light source, reflector and scattering mirror on the basis of Example 1, so that the lighting brightness and light quality are further improved, and can meet higher-end automobile lighting needs.

[0028] Working principle: When the car light bulb is powered on, the lamp tube 2 starts to emit light, and the emitted light is gathered together by the reflector 3 set in a parabolic shape, and then efficiently reflected by the inner surface of the reflector 3, changing the propagation direction. The reflected light reaches the scattering mirror 4 set in an arc shape, and is evenly scattered in all directions by the diamond scattering structure on its inner surface, reducing the local concentration of light;

[0029] The scattered light is almost completely transmitted to the outside of the bulb through the lampshade 5 made of high light transmittance material, and finally forms a soft, uniform, shadow-free high-quality light, which is illuminated on the road ahead. Through the convergence of the reflector 3 and the uniform scattering of the scattering mirror 4, combined with the high light transmittance lampshade 5, the automobile bulb of the utility model can efficiently utilize the light emitted by the lamp tube 2, maximize the utilization rate and transmittance of the light, improve the lighting quality while saving energy consumption, and achieve a comprehensive improvement in the performance of the automobile bulb.
