Detailed ways

The utility model provides a landscape lamp. An example of the growth device made by the utility model is given below to further illustrate the utility model.

Example

This embodiment is a reflective LED landscape lamp used in gardens, as shown in FIG. 1 , comprising a base (1), an LED light source group (2), a lamp body (3), and a curved reflector (4). In order to obtain sufficient light intensity so that the circular area with a diameter of 4.5 meters around the street lamp is effectively illuminated, the base (1) is designed as a disc with a diameter of 25 cm (as shown in Figure 2), and 12 circles are evenly distributed on the disc. The hole is used to place the LED light source, and the sound-activated light-activated switch module is installed under the light source. In the LED light source group (2), each LED light source is arranged at the focal point of a parabolic reflector, as shown in FIG. 3 . The lower half of the lamp body (3) is a 15-centimeter-high cylindrical cylinder, and the upper half is three 40-centimeter-high supports (one of which is hollow for placing lines), and a circular thin Transparent glass (used to block rainwater, insects and ants, etc.). The curved surface of the curved reflector (4) is calculated by computer according to the coordinates of the base light source, the height coordinates of the corresponding curved reflector, the coordinates of the uniform illumination area and the law of light reflection, and then simulated to obtain the radius of curvature at each point of the mirror surface, which is approximately inverted conical , in order to save cost, the inverted conical reflector is directly selected. According to the edge coordinates of the outermost edge of the light source, the height coordinates of the corresponding curved reflector (4), the outermost edge coordinates of the lighting area, and the reflectivity, the slope of the cone is calculated: the curved reflector (4) should use a vertex angle of 102.5 degrees , an inverted conical surface with a height of 10 cm (that is, full-space lighting). All parts of the landscape light (except the light source reflector) are made of transparent hardened glass. When the landscape light is illuminated, the LED light source group (2) on the base emits approximately vertically upward light (because each LED light-emitting point is approximately at the focus of the reflector, the light emitted is approximately vertically upward after reflection, and then the curved surface reflects The mirror (4) reflects the incident light to the road surface to evenly illuminate the road surface.
