Abstract

This creation is a warning light, which includes a lamp housing with an accommodating space, and a light-emitting device and a heating device are arranged in the lamp housing. The heating device is used to provide heat energy to the air in the accommodating space. One side of the heating device is provided with a diversion auxiliary member, which can assist the air in the accommodating space to flow in the accommodating space. When it snows, it passes through the heating device and the diversion auxiliary member. With cooperation, the air in the accommodating space forms a hot air flow and evenly contacts the lamp housing, and then uses the fast-flowing hot air flow to uniformly and comprehensively transfer heat energy to every part of the lamp housing, so that snow cannot be attached to the lamp. The shell enables the light emitted by the light-emitting device to be effectively irradiated to ensure the luminous efficacy of the warning light.

Description

Warning Light

This creation is a kind of warning light, especially a kind of warning light that can generate hot air flow in the light and have uniform and rapid defogging performance.

The existing warning light includes a lamp holder, a light-emitting device and a lamp shade. The light-emitting device is arranged on the lamp holder. The lamp shade is arranged on the lamp holder and covers the light-emitting device. The light-emitting device is protected by the lamp shade and at the same time. The texture on the surface of the lampshade allows the light emitted by the light-emitting device to pass through the surface texture of the lampshade to achieve the desired optical performance for warning purposes.

The above-mentioned existing warning lights are used in a snowy environment. Snow is easy to adhere to the lampshade of the warning lamp and obstruct the light from the lampshade, so that the snow-covered lampshade reduces the original warning luminous efficacy of the warning lamp. In order to improve the adhesion of snow, the existing warning lamp further embeds a plurality of electric heating wires arranged at intervals on the inner surface of the lampshade. These electric heating wires are connected to the power supply through the light-emitting device to be energized and generate heat. The snow on the lampshade melts due to heat and cannot be continuously attached to the lampshade, so as to achieve the purpose of preventing the snow from attaching to the lampshade.

However, the heating wires are arranged on the inner surface of the lampshade at intervals, and the heating wires are not comprehensively arranged on the inner surface of the lampshade. Therefore, in the heating state of the heating wire, the heat energy is concentrated in the section of the lampshade close to the heating wire, and the distance between the lampshade and the heating wire is relatively short. The far section is likely to cause uneven heating of the lampshade due to the slower time of receiving heat energy, which affects the effect of preventing snow from attaching and the luminous efficiency. Moreover, these heating wires are directly buried in the inner surface of the lampshade. Since the lampshade of general warning lights does not use high heat resistance materials, the heat generated by the heating wires is excessively concentrated and directly acts on the light-transmitting lampshade, which is easy to cause Local overheating of the lampshade accelerates the aging of the material of the light-transmitting lampshade, which affects the light transmission performance of the lampshade. Therefore, it is not ideal for the warning lamp to use electric heating wires to generate heat and prevent snow from attaching.

The main purpose of this creation is to provide a warning lamp to improve the problem that the warning lamp adopts the heating wire in the lampshade, and the lampshade is easy to receive the heat energy of the heating wire unevenly and the heat transfer rate is slow, which causes the lampshade to prevent the snow from attaching to the problem. .

In order to achieve the purpose of the previous disclosure, the warning lights of this creation include: A lamp housing, which forms an accommodating space inside; A light emitting device, which is arranged in the lamp housing and located in the accommodating space; A heating device arranged in the lamp housing and located in the accommodating space, and used to provide heat energy to the air in the accommodating space; and A guide auxiliary member is arranged in the accommodating space of the lamp housing and located at one side of the heating device, and assists the heated air in the accommodating space to flow in the accommodating space.

With the above-mentioned overall composition and construction of the warning light, it has at least the following advantages: 1. Improve the performance of preventing snow from attaching: The warning light uses a heating device to provide heat to the air inside the lamp housing in a snowy environment, and is formed by the diversion of the heated air by the diversion aid Hot air flow, through the hot air flow inside the lamp housing, and quickly transfer heat energy to every part of the lamp housing, effectively and comprehensively let the snow falling on the lamp housing absorb heat and melt, so that the snow cannot continue to adhere On the lamp housing, the luminous efficacy of the warning lamp should be maintained. 2. Effectively disperse heat energy evenly and avoid excessive concentration of heat energy: As mentioned above, the warning light uses a combination of a heating device installed in the lamp housing and a diversion auxiliary component to heat the air inside the lamp housing and heat the air inside the lamp housing. The heated air provides a diversion function to form a hot air flow. By the hot air flow inside the lamp housing, the heat energy is evenly distributed and transferred to every part of the lamp housing, and the heating temperature of the heating device can be controlled, so it can effectively avoid Excessive heat energy is concentrated in the lamp housing, which can improve the problem that the lamp cover of the existing warning lamp is prone to material aging due to local overheating.

The warning light of the present creation can further utilize that the heating device includes at least one heating element, and the heating element is provided with a heat dissipation fin set, and the guide auxiliary element includes at least one fan, and the fan is arranged on one side of the heat dissipation fin set. The heat dissipation fin group disperses the heat generated by the heating element, and uses the fan to actively generate air flow driving performance, which can further enhance the convection performance of the hot air.

As shown in FIGS. 1 to 3 and 5, the creative warning light includes a lamp housing 10, a light emitting device 20, a heating device 30 and a diversion auxiliary member 40.
