Example one

As shown in fig. 1 to 5, the present embodiment discloses a signal lamp including a housing 1 and a face mask 2, which constitute a housing of a lamp. The light source of the lamp is an LED light source, and may be specifically an LED light emitting diode 4, which is not limited herein, and has a plurality of LED light sources, and the plurality of LED light sources are carried by the PCB 3. The signal lamp also comprises a shading edge 5 arranged between the PCB board 3 and the face mask 2, and the shading edge 5 is provided with light holes 53 in one-to-one correspondence with the LED light-emitting diodes 4. Hide in the signal lamp along 5, make the signal lamp can avoid the installation to expose and hide along 5, optimized the outside mechanical structure of signal lamp, do not fear bad weather such as strong stormy snow. Meanwhile, the shielding edge 5 is arranged in the signal lamp, assembly can be completed when the signal lamp leaves a factory, and site construction is more convenient.

In this embodiment, the shielding edge 5 includes a reverse-mounted panel 51 and a side wall 52, the reverse-mounted panel 51 and the side wall 52 form the shielding edge 5 in a bottle cap shape, the side wall 52 is used for installing the shielding edge 5 on the PCB board 3, the reverse-mounted panel 51 is used for setting the light hole 53 and covering the part except the LED 4 which needs to be exposed, so as to realize shielding the interference light at a certain angle from the outside to directly irradiate the signal lamp. On the inner side of the shade 5, that is, the inner side of the bottle cap shape, the shade 5 further has a light-transmitting tube 54 corresponding to the light-transmitting hole 53 one by one and sleeved on the LED 4, the light-transmitting tube 54 is disposed on the reverse mounting panel 51 and sleeved with the LED 4 on the inner side of the shade 5, and therefore, in this embodiment, the height of the sidewall 52 is higher than the height of the LED 4. Each LED 4 is independently shielded from interference light, so that the shielding effect on the interference light is better, and the effect that the large-size signal lamp cannot realize integral shielding cannot be achieved.

The size of the light hole 53 is designed according to the light emitting size of a single LED 4, so that external strong light interference at a certain angle can be shielded; the light hole 53 is opened at a position opposite to the LED 4, the light pipe 54 covers the light path, the length of the light pipe 54 is selected according to the light emitting angle of the LED 4, the smaller the angle is, the shorter the light pipe 54 is, and the shortest the angle is, the shortest the length can be 0, that is, the light pipe 54 is not provided. The specific length of the light-transmitting tube 54 can be determined by a person skilled in the art through experiments according to the actual working scene and working requirements of the signal lamp, and is not limited herein; the distance between the light-emitting surface of the shading edge 5 and the effective light-emitting surface of the LED 4 is the length of the light-transmitting tube 54, and different shading angles can be realized by adjusting the length.

In fig. 3, d represents the diameter of the LED 4, L represents the distance from the light emitting surface of the shielding edge 5 to the effective light emitting surface of the LED 4, and the ratio of L to d is the length ratio between the shielding edge 5 and the light emitting diameter, and the higher the ratio of the length ratio is, the larger the shielding range of the external interference light is, but the smaller the angle at which the signal lamp is observed is. D represents the diameter of the light hole 53, since the light emitted from the LED 4 generally has a certain angle, the value of D needs to be determined according to the light emitting angle to reduce the blockage of normal light emission; b is the mounting clearance between the surface of the mask 5 and the face mask 2.

As shown in fig. 2, the light-transmitting hole 53 and the light-transmitting tube 54 may be designed in a circular shape, and their shapes may be changed according to the usual position of the observer and the disturbing light source. For example, if the main interference source of the signal lamp is the sunlight located at a high position and the observer located at the bottom is located at a low position, the shielding edge 5 mainly shields the interference light from the upper part and needs to have a larger viewing angle at the lower part, and based on this, the shape of the light transmission hole 53 can be designed into an ellipse with a longer lower opening, and the shape of the cross section of the light transmission tube 54 is also designed into an ellipse with a longer lower opening.

In this embodiment, the mask 5 may be a plastic mask or a glass mask or a metal mask. When the shade 5 is a plastic shade or a glass shade, the inverted panel 51, the sidewall 52, the light hole 53 and the light pipe 54 can be directly and integrally formed by a mold; when the shielding edge 5 is a metal shielding edge, the reverse panel 51, the sidewall 52, the light hole 53 and the light pipe 54 may be integrally formed by a casting process, or the reverse panel 51 may be punched to form the light hole 53 structure, and then the sidewall 52 and the light pipe 54 are welded to the reverse panel 51.

The connection between the side wall 52 and the PCB 3 may be selected by soldering, bonding, screwing, etc. according to the wiring of the PCB 3 and the material of the bezel 5, which is not limited herein.

In order to reduce the influence of incident interference light on the signal light source, the surface of the shielding edge 5 is coated with black matt paint. The black matt paint is the existing mature technology and is not limited herein.

The signal lamp disclosed by the embodiment can ensure the indicating effect of the signal lamp and the convenience of construction, and brings additional benefits not only to the signal lamp, but also to the design and manufacture of the rod piece. Because the shielding edge 5 is not exposed, the load increase of the shielding edge 5 on the rod after snow and ice coating in winter is avoided, therefore, the rod does not need to bear excessive load in winter, and the material of the rod is saved. At the same time of saving materials, because the situation that the shade 5 falls snow and covers ice in winter does not exist, the potential safety hazard caused by the droop of the rod piece or the signal lamp is eliminated.

Example two

As shown in fig. 4, the present embodiment is different from the first embodiment in that, in the present embodiment, the shielding edge 5 includes a front-mounted panel 55, the light-transmitting hole 53 is disposed on the front-mounted panel 55, the LED 4 passes through the light-transmitting hole 53, and the light-transmitting tube 54 is sleeved on the LED 4 between the shielding edge 5 and the mask 2.

In this embodiment, since there is no sidewall 52 structure in the first embodiment, the LED 4 needs to be inserted into the light hole 53 of the front panel 55, and the light pipe 54 can only be sleeved on the LED 4 outside the front panel 55, i.e. between the shielding edge 5 and the mask 2. The front panel 55 is closely attached to the PCB 3 and fixed thereto by welding, bonding, screwing, or the like, but not limited thereto, and the light transmitting tube 54 is provided outside the front panel 55 and may be integrally formed with the front panel 55 or welded to the front panel 55.

EXAMPLE III

As shown in fig. 5, the difference between this embodiment and the first and second embodiments is that in this embodiment, the shielding edge 5 is a film shielding edge 56, and there is no structure of the side wall 52 in the first embodiment, nor the light-transmitting tube 54 in the first or second embodiment, and therefore, the film shielding edge 56 is directly attached to the inner wall of the mask 2.

It has been clarified in the first embodiment that the length of the light-transmitting tube 54 is selected according to the light-emitting angle of the LED 4, and the smaller the angle, the shorter the light-transmitting tube 54, and therefore, there is a case where the length of the light-transmitting tube 54 is the shortest, that is, the length of the light-transmitting tube 54 is 0, and therefore, this embodiment is a case where the length of the light-transmitting tube 54 is the shortest, that is, the length of the light-transmitting tube 54 is 0.

The film shielding edge 56 is adopted, when the light-emitting angle of the LED 4 is small, the shielding effect can be increased by increasing the L/d ratio, so that the light-transmitting tube 54 can be omitted, the transparent mask 2 can be directly printed with a light-tight paint film, the good light shielding effect can be realized, and the product cost can be reduced.
