DETAILED DESCRIPTION OF THE INVENTION

[0023] Drawings and detailed embodiments are combined hereinafter to elaborate the technical principles of the present invention.

Embodiment 1

[0024] As shown in FIGS. 1-6, in this embodiment, the large-angle LED working lamp of the present invention comprises a shell 1, a lampshade 2 clamped with the shell 1, light-emitting units arranged in the shell 1 and a connector 3 electrically connected with a power generation unit. The light emitting unit comprises a circuit board 7 and a convex lens 8. A light-emitting diode 71 is arranged on the circuit board 7, and the convex lens 8 covers the light-emitting diode 71.

[0025] Compared with the prior art, three light-emitting units are arranged in the LED working lamp of the present invention, comprising a central light-emitting unit 5 and two side light-emitting units 6 that are symmetrically arranged on the two sides of the central light-emitting unit 5. The angle formed between each side light-emitting unit 6 and the central light-emitting unit 5 is 20-30 degrees. During operation, the light-emitting direction of the central lens faces right ahead, and the light-emitting directions of the two side lenses and the central lens respectively form an angle of 40-60 degrees. Therefore, the light-emitting angles in three different directions can be formed so that the illuminating angle can reach 90-120 degrees, greatly reducing the number of working lamps, and achieving a uniform light intensity and a high utilization rate.

[0026] Further, two light-emitting diodes 71 are arranged on the circuit board 7 so that the light intensity can be effectively improved. Two lenses 8 are arranged to correspond to the two light-emitting diodes 71.

[0027] To ensure the heat dissipation effect, in this embodiment, the shell 1 is made of aluminum alloy, and a plurality of heat dissipation fins 11 are integrally formed on the shell 1 for further enhancing the heat dissipation efficiency.

[0028] Further, the lampshade 2 is made of a PC material with an ideal light transmission. A vent valve 9 is arranged on the shell 1, achieving good air circulation in the shell 1.

Embodiment 2

[0029] This embodiment provides an automobile headlamp, which comprises an LED working lamp and a mounting frame 4 used for being connected with the automobile, wherein the mounting frame 4 is connected to the bottom of the shell 1 in a bolting mode.

[0030] The operating principle of the present invention is the following:

[0031] Through the central light-emitting unit 5 and the two side light-emitting units 6 that are symmetrically arranged on the two sides of the central light-emitting unit 5, during operation, the light-emitting direction of the central lens faces right ahead, and the light-emitting directions of the two side lenses and the central lens respectively form an angle of 40-60 degrees. Therefore, the light-emitting angles in three different directions can be formed so that the illuminating angle can reach 90-120 degrees, greatly reducing the number of working lamps, and achieving a uniform light intensity and a high utilization rate.

[0032] The description of above embodiments allows those skilled in the art to realize or use the present invention. Without departing from the spirit and essence of the present invention, those skilled in the art can combine, change or modify correspondingly according to the present invention. Therefore, the protective range of the present invention should not be limited to the embodiments above but conform to the widest protective range which is consistent with the principles and innovative characteristics of the present invention.
