Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a blind area monitoring alarm lamp, which includes a discrete plate 1, a light source 2, a circuit board 3, a light guide 4 and a lamp cover 5, wherein the lamp cover 5 and the discrete plate 1 form a lamp housing, the circuit board 3 and the light guide 4 are integrated in the lamp housing, the light source 2 is mounted on the circuit board 3, the front surface of the light guide 4 is planar, the back surface of the light guide 4 is convex, the lower portion of the front surface of the light guide 4 is a light incident surface, the upper portion of the front surface is a light emitting surface 4.4, the light incident surface of the light guide 4 corresponds to the light source 2, the light emitting surface 4.4 of the light guide 4 corresponds to the discrete plate 1, a light collector 4.1 is disposed at a position on the light incident surface of the light guide 4 and opposite to the light source 2, the lower portion of the back surface of the light guide 4 is a first reflecting surface 4.2 in a zigzag shape, and the upper portion of the back surface is a second reflecting, the light entry face and the light exit face 4.4 of the light guide 4 are on the same plane.
In the use, concentrate on first plane of reflection 4.2 through spotlight ware 4.1 and carry out the total reflection with light, rethread light guide 4's second plane of reflection 4.3 with light total reflection to going out plain noodles 4.4, export again after the even light effect of board 1 is dispersed to last, the light that so passes through is even and luminous area is great, avoids appearing warning pattern local luminance inequality.
The light source 2 of blind area monitoring alarm lamp is 3 LED lamps, and no matter how many LED lamps quantity is in practical application, all belongs to this patent protection scope. Arrange light guide 4 structure in 2 the place ahead of light source, light changes the angle with the light change who diverges angle about 120 when passing through spotlight ware 4.1 and changes into parallel light, the loss of light has been reduced, parallel light direct reflection after concentrating to first plane of reflection 4.2, carry out the first total reflection of light here, light after the reflection carries out the second total reflection on the second plane of reflection 4.3 of cockscomb structure, make light send along the play plain noodles of difference, the light-emitting area has been enlarged, when light sees through discrete board 1, even light effect through discrete board 1 makes light can even output, discrete board 1's luminousness is relevant with its material density, can be according to the actual light-emitting effect in later stage, adjust discrete board 1's material density and reach different luminousness, thereby need not to adjust light guide 4 major structure, just can realize different luminance effects.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
