Abstract

The utility model relates to an indicating device of a semiconductor light emitting element, which is used for indicating marks in public places, comprising a shell, a power supply system, a semiconductor light emitting element, and an indicator plate. The semiconductor light emitting element is arranged in an inner cavity of the shell, one end of the indicator plate is protruded out of the shell and the other end is fixed to the lower part of the semiconductor light emitting element in the inner cavity of the shell, causing light generated by the semiconductor light emitting element to enter the indicator plate form a side face; characters or figures on the indicator plate are formed by etching transparent materials, and different colors can be coated on the characters or figures. The utility model has the advantages of simple structure, selectable colors and low cost, and besides, contents on the indicator plate can be observed from the face and the inverse sides.

Description

Semiconductor light-emitting elements Warning Mark device

The utility model relates to the cue mark of public place, particularly adopts the Warning Mark device of electroluminescence.

At present Warning Mark device in public places often adopts incandescent lamp, fluorescent lamp etc. to be contained in as light emitting source to carry out on the indicator board of character or figure work, and their power consumptions are big, the life-span short; The electroluminescent Evacuation Indicatory Sign device of Chinese patent 92202163, though power consumption is little, color is single, circuit complexity, cost height; The light emitting diode diffuse reflection indicating device of Chinese patent 94222252 is though solved the problems referred to above, complex manufacturing technology, cost height.

The purpose of this utility model is to provide a kind of semiconductor light-emitting elements side simple in structure to inject formula Warning Mark device.

The purpose of this utility model is achieved in that semiconductor light-emitting elements Warning Mark device comprises housing, electric power system, semiconductor light-emitting elements and indicator board.Semiconductor light-emitting elements is installed in the housing inner chamber, and indicator board one end stretches out outside the housing, and the other end is fixed to the below of semiconductor light-emitting elements in the housing inner chamber, and the light that makes semiconductor light-emitting elements send is injected indicator board from the side; Character on the indicator board or figure are that the light transmissive material etching is formed.

The utility model is installed in the housing inner chamber because only need respectively with an end of semiconductor light-emitting elements and indicator board, the light that semiconductor light-emitting elements is sent is injected indicator board from the side, so can see the character or the figure of required indication at the positive and negative of indicator board, so structure is simple especially; Character or figure on the indicator board also forms for common light transmissive material etching simultaneously, is coated with on character or figure with different pigment, can show corresponding color on the indicator board, so cost is very low.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the outline drawing and the positive topography of the utility model semiconductor light-emitting elements Warning Mark device

Fig. 2 is the enlarged drawing of Figure 1A-A cutaway view

Fig. 3 is an electric power system operation principle block diagram

Fig. 1, Figure 2 shows that the utility model semiconductor light-emitting elements Warning Mark device, comprise housing 1, be installed in electric power system 2, semiconductor light-emitting elements 3 and the indicator board 4 of housing inner chamber 6.

Among Fig. 1, the embodiment shown in Figure 2, semiconductor light-emitting elements 3 is a semiconductor light-emitting-diode, and indicator board 4 is character or the figures 5 with glass required indication on its surface etch, as " outlet ".Semiconductor light-emitting elements 3 is installed in housing inner chamber 6, indicator board 4 one ends stretch out outside the housing 1, the other end is fixed to the below of semiconductor light-emitting elements 3 in the housing inner chamber 6, and the top of indicator board 4 contacts with the top of semiconductor light-emitting elements 3, at this moment the light that sends of semiconductor light-emitting elements 3 can be injected indicator board to the full extent from the side, makes character or figure display effect the best on the indicator board.

Fig. 1, Fig. 2, when Figure 3 shows that the work of the utility model semiconductor light-emitting elements Warning Mark device, under AC220V powers normal situation, electric power system 2 is in normal operating conditions, by step-down, the circuit of part such as rectification is to semiconductor light-emitting elements 3 power supplies, also battery 10 is charged simultaneously, at this moment semiconductor light-emitting elements 3 emits beam 7, inject from the side of indicator board 4 when being carved with comparatively coarse surperficial of character or figure 5, produce the reverberation 8 and the refract light 9 of different directions on character or the figure 5, make and to know character or the figure of seeing on the indicator board 4 from the different angles of positive and negative; Under the situation that AC220V has a power failure or voltage pole is low, battery 10 continues powered operation above one hour to semiconductor light-emitting elements 3 automatically; When AC220V recovers just often, circuit is got back to normal operating conditions automatically.Wherein glass can be electroplated into mirror, and character or figure also can be coated color, to strengthen the visual effect of indicator board 4.
