Problems solved by technology

[0006] However, since the heating element on the inner surface of the cover main body described in Patent Document 1 is a strip-shaped metal, when viewed from a distance, the light-emitting part formed by the LED illuminant of the signal lamp device will be blocked by the strip-shaped heating element. Concerns about the visibility of signal lights
In addition, the area where heat is generated by the heating element is relatively small compared to the light-emitting part, so there is also a problem that the effect of preventing snow adhesion is expected to be insufficient.
In addition, there are problems that the shape of the heating element is complicated, the manufacturing cost becomes high, and the attachment of the heating element to the cover body is difficult.

Embodiment 1

[0064] First, as an example of the present invention, a three-lamp signal lamp device according to an embodiment of the present invention will be described.figure 1 A front view showing a three-lamp signal lamp device 1 (hereinafter simply referred to as "signal lamp device 1") of this embodiment, figure 2 shows a top view of the signal lamp device 1, image 3 Represents the rear view of the signal lamp device 1, Figure 4 shows the right side view of the signal lamp device 1, Figure 5 A left side view of the signal lamp device 1 is shown. In addition, the number of signal lamps may be single, or may be multiple other than three.

[0065] Such as figure 1 As illustrated, the signal lamp device 1 of this embodiment is a conventional horizontally elongated signal lamp device configured to be able to light up three colors of red, yellow and green. Three light emitting parts 110, 210, 310 having a diameter of about 30 cm are provided in the signal lamp device 1 . The light ...

no. 2 example

[0088] Next, a second example according to one embodiment of the present invention will be described. Figure 23 It shows the front view of the signal lamp apparatus 1A of 2nd Example. The signal lamp device 1A is the same as the first embodiment, and is also a three-lamp signal lamp device. The difference lies in that the opening and closing cover part 400 has three light emitting parts 410 . The opening and closing cover 400 is fixed to the main body 10A in a closed state by fixing bolts 40 . At both end portions of the main body 10A, similarly to the first embodiment, brackets 30 for fixing are provided.

[0089] Figure 24 said pass Figure 23 A cross-sectional view of the signal lamp device 1A observed on the D-D cross-section. The heating unit 440 is held by being sandwiched between the gasket pressing rib 442 and the end of the ring-shaped rising portion 452 of the spacer 450 via glass gaskets 441 and 443 formed on the opening and closing cover. The inner end surfa...

Abstract

A signal lamp 1 for emitting signal light is provided with: a light emitter unit 70 having a light emitter, i.e., a light source of the signal light; a main body 10 for housing the light emitter unit;and a heat generating unit 140, which is disposed, in the main body 10, on an optical path of the signal light emitted from the light emitter unit 70, and which has a board-shaped heat generating glass having a light transmitting conductive thin film on the surface, said heat generating glass generating heat when the conductive thin film is supplied with power via a pair of electrodes.

Description

technical field [0001] The invention relates to a signal lamp device. Background technique [0002] In the case of a signal light device installed at a road intersection, etc., when the signal light is installed in an area where snowfall occurs, there is a problem that snow adheres to the front surface of the illuminant, making it difficult to see the light. Conventionally, in a signal lamp device using an incandescent lamp as a luminous body, the snow adhering to the front surface of the luminous body is almost melted by the heat emitted by the incandescent lamp, so the problem of snow adhering to the signal lamp device is less likely to occur. However, in signal lamp devices that use light-emitting diodes (LEDs) as illuminants, which have become popular in recent years from the viewpoint of power saving and ease of maintenance, LEDs generate very little heat compared to incandescent lamps, so they are realized by heat. Insufficient melting of the snow caused the problem o...
