Abstract

The utility model discloses an electric colored indicator used in public bus; wherein, a light guide plate(such as an acrylic plate) is inscribed with corresponding characters and numbers with an internally colored carving groove. A white light absorbing metallic plate is used as a dorsal plate, and a frame consists of a groove type shaping article which is made from plastic, aluminum or other metallic materials. The light source is a circuit board consisting of a plurality of light emitting diodes, resistors and power leads. Any lateral, laterals of the frame or the whole frame can be inserted into the power supply circuit board, so as to enable the light to irradiate in required direction.

Description

The electronic color direction board

Affiliated technical field

The utility model relates to the electronic color direction board that a kind of bus uses.

Background technology

Be used to refer on the existing bus this bus or train route line and beginning arrive at a station employed light emitting directory board used be to do light source with interior dress incandescent lamp bulb.The problem that exists is: color is single, and sharpness is low, does not have stereoscopic sensation, and shockproof properties is poor, and casing is thick and heavy.

Summary of the invention

In order to overcome above deficiency, the utility model provides a kind of electronic color direction board, and this electronic color signboard structure is simple, easy for installation, the saving space.

The technical solution adopted in the utility model is: the main body of direction board is a light guide plate (as acrylic board etc.), on light guide plate, related text and numeral are carved into groove, scribble color in the groove, do frame with plastics or shape around the light guide plate, the light source of being made up of a plurality of light emitting diodes is housed in the frame.The light guide plate back side is the thin extinction metal blank of one deck, uses so that literal on the light-passing board or numeral are more clear.Energized, light source irradiation make it high-visible by the cutting of literal on the light guide plate and numeral and refraction, the reflection of the color in the cutting on light-passing board.Light source can be used multiple color.

The beneficial effects of the utility model are: the sharpness height, and shockproof properties is good, and whole frivolous, the life-span is long, and stereoscopic sensation is arranged, and light is soft, does not generate heat.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is both planimetric maps of embodiment of the utility model;

Fig. 2 is an outboard profile;

Fig. 3 is the circuit of light sources schematic diagram.

Among the figure: 1. light guide plate 2. frames, 3. related text and digital 4. power leads, 5. wiring boards, 6. light emitting diodes, 7. backboards

Embodiment

As shown in Figure 1 and Figure 2: carve related text and numeral (3) or pattern, cutting inner coating color with cutting above the light guide plate (1) (as acrylic board).Make backboard (7) with the extinction sheet metal of white, do frame (2) with the grooved section bar that plastics, aluminium or other metal are manufactured.

Light source as shown in Figure 3, the wiring board of forming by a plurality of light emitting diodes (6), resistance and power lead (4) (5).

Will be arbitrarily on one side, several limit or all insert power circuit plate (5) in frame (2) grooves so that light is to the direction irradiation of needs, with frame (2) with light guide plate (1) with clip together with the backboard (7) of its identical size and fix extracting power supply cord (4).

Claims

1. electronic color direction board, by top with cutting carve related text and numeral (3) and the grooved section bar manufactured at the backboard (7) of the light guide plate (1) of cutting inner coating color-make, with plastics, aluminium or other metal as acrylic board etc., of the extinction sheet metal of white do frame (2) and with and the light source of wiring board (5) formation formed with a plurality of light emitting diodes (6), resistance and power lead (4) form.

2. electronic color direction board according to claim 1 is characterized in that: can will insert the power circuit plate in one side, several limit or whole frame (2) grooves arbitrarily.
