Abstract

A vehicle lamp with snow melting function has a heating module and a control unit arranged in a vehicle lamp body. The heating module includes an invisible light source, a temperature sensor and a driving board. When the measured temperature of a vehicle lamp is lower than a preset temperature, the control unit turns on the heating module to heat the lampshade, and when the measured temperature of the vehicle lamp is higher than a preset temperature, the control unit turns off the invisible light source, By turning on the heat generated by the invisible light source to melt the snow or icing on the lampshade, the heating and melting of the snow will not hinder the lighting effect of the car light source, so as to maintain the safety of passers-by.

Description

Car lights with snow melting function

This creation is about car lamp devices, especially a car lamp device that uses an invisible light source as a heating source to melt snow.

In countries with high latitudes or high mountains, snowfall is usually encountered in winter. The continuous snowfall or snow or icing will cover the surface of the lampshade or even the entire vehicle body, and the snowfall covering the surface of the lampshade Or snow or icing will cause the lights of the car to be obscured, which will affect the driver's line of sight.

Therefore, car lights used in areas prone to snow must be equipped with devices that can melt snow or ice. At present, most of them use additional hot wires on the lampshade or place a conductive heating device to generate heat to achieve snow and ice melting. However, installing a heating wire on the lampshade usually produces the following conditions. For headlights, the heating wire on the lampshade will block part of the illuminating beam of the car light, resulting in damage to the headlight's low-light or high-light shape, which greatly affects Use the safety of passersby.

Based on the above-mentioned deficiencies, the purpose of this creation is to provide a car light with snow melting function, especially a light source that uses invisible light as a heat source to emit invisible light to heat the lampshade. The heat generated by the invisible light melts the snow or icing on the lampshade, and will not hinder the lighting effect of the car lights while heating.

According to the purpose of this creation, a car lamp with snow melting function is provided, which includes a car lamp body, which at least includes a lampshade, a near lamp module, a far lamp module, and a heating module arranged in sequence And a lamp housing. The heating module is arranged inside the car lamp body, and has an invisible light source, a driving board, and a temperature sensor. The temperature sensor is used to sense the temperature of a car lamp. The light emitting direction of the light source faces the lampshade, and the vehicle lamp body further includes a control unit electrically connected to the heating module.

When the temperature of the vehicle lamp is lower than a first preset temperature, the control unit turns on the heating module to light up the invisible light source, so that the invisible light source heats the lampshade.

When the temperature of the vehicle lamp is higher than a second preset temperature, the control unit turns off the heating module to extinguish the invisible light source, so that the invisible light source stops heating the lampshade.

When the near light module or the far light module is activated, the control unit will turn on the heating module so that the invisible light source heats the lampshade until the temperature sensor detects the second preset temperature before turning off the The heating module is used to extinguish the invisible light source, so that the invisible light source stops heating the lampshade.

Figure 1 is an exploded view of the components of this creative implementation mode.

Figure 2 is a schematic diagram of the implementation of this creation.

Fig. 3 is a block diagram of the components of the car lamp body of the present creative embodiment.

In order to clearly explain the specific implementation, structure and effects of this creation, an example is provided and illustrated with the drawings as follows: Please refer to Figure 1 and Figure 3 for the implementation of the creation, which shows a car light with snow melting function. , Including a car lamp body 10, the car lamp body 10 at least includes a lamp shade 11, a near light module 12, a far light module 13, a heating module 15 and a lamp housing 19 arranged in sequence, The heating module 15 has an invisible light source 151, a driving board 152, and a temperature sensor (not shown in the figure). The driving board 152 is disposed on a fixing base 16, and the direction of the invisible light source 151 faces the The lampshade 11 is used for sensing the temperature of a vehicle lamp. In this embodiment, the vehicle lamp body 10 further includes a control unit 17 electrically connected to the heating module 15.

In this embodiment, the temperature sensor may be disposed on the driving board 152 for sensing the temperature around the lampshade 11. When the temperature of the vehicle lamp is lower than a first preset temperature, the control unit 17 turns on the heating module 15 to light up the invisible light source 151 so that the invisible light source 151 emits invisible light to directly heat the lampshade 11 , To melt the snow or icing accumulated outside the lampshade 11 until the snow or icing is completely relieved, or when the temperature of the vehicle lamp is higher than a second preset temperature, the control unit 17 turns off the heating module 15 to extinguish The invisible light source 151 stops heating the lampshade 11 to avoid potential damage to other parts. In other embodiments, the temperature sensor can also be arranged at any position on the inner surface of the lamp housing 19 or on the surface of the lamp cover 11 to sense the surface temperature of the lamp cover 11.

The first preset temperature can be between -10 degrees and 15 degrees. Preferably, when the first preset temperature is ≦5 degrees, the control unit 17 activates the heating module 15 to make the invisible light source 151 heats the lampshade 11 to melt the snow or ice accumulated on the lampshade 11.

The second preset temperature can be between 20 degrees and 40 degrees. Preferably, when the second preset temperature is ≧30 degrees, the control unit 17 turns off the heating module 15 to allow the invisible light source 151 Stop heating the lampshade 11 to avoid damage to the car lights due to excessive temperature difference or high temperature.

In addition, when the near light module 12 or the far light module 13 is activated, the control unit 17 turns on the heating module 15 so that the invisible light source 151 heats the lampshade 11 until the temperature sensor detects the second preset After the temperature, the control unit 17 turns off the heating module 15 so that the invisible light source 151 stops heating the lampshade.

This creation uses the invisible light source 151 installed inside the car lamp body 10, and the invisible light source 151 generates heat to melt the snow or ice on the lampshade, heating and melting the snow without hindering the optical effect of the car light source, so as to maintain the utility. Safety of passersby.
