Disclosed is an LED light fitting, comprising a light-convergent cover (2), LED lighting (3), a lamp housing (4) and heat dissipation pins (5), wherein the LED lighting (3) is uniformly distributed on the upper surface of the lamp housing (4); the light-convergent cover (2) is provided above the LED lighting (3) and connected to the upper surface of the lamp housing (4); reflection blocks (6) are provided within the light-convergent cover (2); and the heat dissipation pins (5) are distributed uniformly on the lower surface of the lamp housing (4). A transparent cover (1) is provided above the lamp housing (4), the transparent cover (1) being connected with the lamp housing (4). The lamp housing (4) is designed in a planar form, a circular arc form, and a prism cylinder form. The clearance between the heat dissipation pins (5) is 10 - 25 mm, and the height of the heat dissipation pins (5) is 30 - 70 mm. The light-convergent cover (2) is of a hollow conical platform shape, the height thereof is 20 - 50 mm, the diameter of the upper opening is 20 - 50 mm, and the diameter of the lower opening is 8 - 20 mm. In the LED light fitting, more than 95% of the light emitted from the LED lighting (3) is reflected onto the object needing to be illuminated, such that the lighting efficiency of the LED lighting fitting is improved, consumption of the energy source is reduced, the structure is simple and the use thereof is convenient. |
