Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.

In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present application. References to "first," "second," etc. in this application are intended to distinguish between similar items and not necessarily to describe a particular order or sequence.

Example 1: a traffic signal lamp, see figure 1, includes casing 1, and casing 1 contains curved lateral wall, and the lateral wall rear sets up back recess 2, and the casing front portion utilizes light guide plate 5 and the board 6 that softens to seal, and overall structure is the bowl form.

A control circuit board is arranged in the rear groove 2 of the shell and is connected with an LED panel to control the LED to emit red, yellow and green light. The light emitting source can be formed by uniformly arranging 7 high-power LEDs on the LED panel, the center of the panel is provided with one LED, 6 LEDs are arranged on the circumference of a certain radius on the periphery, and the uniformity of emergent light can be ensured as far as possible by the uniformly arranged LED lamp beads.

Fix solar panel 4 on the LED panel, see fig. 2 and 3, solar panel 4 is the light-transmitting member that the upper surface set up spherical protrusion 41, and the inside LED lamp pearl that holds of spherical protrusion 41, its top surface are the horizontal plane, utilize the lateral wall thickness of spherical protrusion 41 to realize gathering of light.

The front end of the shell 1 is composed of a light guide plate 5 and a light softening plate 6, the light guide plate 5 is shown in fig. 4, and dense concentric circular convex ribs are arranged on the surface of one side of the light guide plate facing the outside of the shell and used for realizing light collimation; the light diffuser 6, see fig. 5, has an array of particles 61 on its surface facing the outside of the housing for scattering light. Specifically, the light-gathering plate 4 gathers and controls the light emitted by the LED within the range of the lampshade; the light guide plate 5 is a Fresnel lens and is used for collimating light rays so that the light rays emitted by the LED are horizontally emitted; the light diffusing plate 6 allows light emitted from the LEDs to be uniformly irradiated to achieve a uniform surface light source.
