The functions of indicator lights are generally classified into main warning, main attention, caution and warning lights. Because the conventional indicator lamp with different chromaticities has low brightness or has the problem of light crosstalk, the effects of gathering light beams and improving the brightness uniformity of the indicator lamp cannot be achieved, and the indicating illumination effect is not ideal.

the cylindrical bracket is arranged on the top surface of the light source circuit board and is positioned inside the panel accommodating through hole, the cylindrical bracket extends vertically and surrounds the outer side of the RGBW four-color LED, and preferably, the cylindrical bracket is made of metal; and the number of the first and second groups,
the light-transmitting label is arranged inside the cylindrical support and is positioned right above the RGBW four-color LED, and the light-transmitting label is fixedly connected with the cylindrical support;
the top surface of the light guide panel, the top surface of the cylindrical support and the top surface of the light-transmitting sign are positioned on the same horizontal plane.
As the preferred scheme of the lighting structure of the indicating lamp with different colors of the light guide plate, the light-transmitting sign adopts aviation organic glass.
As a preferred scheme of the lighting structure of the indicating lamps with different chromaticities of the light guide plate, the bottom surface of the light-transmitting sign is a paraboloid or an arc surface so as to converge light beams emitted by the RGBW four-color LEDs.
As a preferred scheme of the lighting structure of the different chromaticity indicating lamps of the light guide plate, the cylindrical support is provided with a support positioning inner edge, the light-transmitting sign is provided with a sign positioning outer edge, and the support positioning inner edge is vertically abutted against the sign positioning outer edge.
As a preferable scheme of the lighting structure of the indicating lamp with different colors of the light guide plate, the light-transmitting sign and the cylindrical support are fixedly connected in an adhesion mode.
Compared with the prior art, the invention has the beneficial effects that: the light beams emitted by the RGBW four-color LED upwards pass through the light-transmitting sign, so that the illumination brightness and uniformity of the light-transmitting sign are effectively improved, different chromaticities can be displayed, and the light-transmitting sign has an excellent illumination effect.

Detailed Description
The invention will be described in further detail below with reference to specific embodiments and drawings. Here, the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 3, the lighting structure of the different chromaticity indicator lamps of the light guide plate is shown.
The lighting structure of the indicating lamp with different chromaticities of the light guide plate comprises a fixed bottom plate 1, a light guide panel 2, a light source circuit board 3, a cylindrical support 4, a light-transmitting sign 5 and the like.
The light guide panel is arranged on the top surface of the fixed base plate. The light guide panel is formed with a panel receiving through-hole. The panel receiving through-hole extends vertically.
The light source circuit board is arranged on the top surface of the fixed base plate and is positioned inside the panel accommodating through hole. The light source circuit board has an RGBW four-color LED 30. The RGBW four-color LED emits light upwards.
The cylindrical support is arranged on the top surface of the light source circuit board and is positioned inside the panel accommodating through hole. The cylindrical support extends vertically and surrounds the outer side of the RGBW four-color LED. Preferably, the cylindrical support is made of metal, and can play a role in blocking light and isolating light.
The light-transmissive sign is arranged inside the cylindrical support and directly over the RGBW four-color LED. The light-transmitting sign is fixedly connected with the cylindrical support.
The RGBW four-color LEDs of the light source circuit board emit light upwards, the light passes through the light-transmitting sign to become approximately parallel light beams, and the light beams are uniformly emitted out through the surface of the light-transmitting sign. Preferably, the aviation organic glass sign 4 is square in shape, 1-2mm in thickness, and the light incident surface is a paraboloid or an arc surface. It can be seen that the light beams emitted by the RGBW four-color LED are refracted by the light-transmitting sign to achieve the light beam gathering effect, so that the illumination brightness and uniformity of the indicator lamp are improved, and the characters can display different brightness.
The foregoing merely represents embodiments of the invention, which are described in some detail and detail, and therefore should not be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
