Embodiment Construction

[0012] The embodiment is a solar phantom lamp with a light source rated power of 20W. Install the 40W / 19.2V photovoltaic panel (1) on the top of the lamp housing cover. Adopt 40 pieces of 5730-type 0.5W LED chips, form a planar LED light source board (2) through 10 parallel and 4 strings, and assemble it under the lamp housing cover (3). A semi-elliptical transparent lampshade (4) is adopted to be assembled under the lamp housing cover. Lampshade is installed on the small semi-elliptic lamp holder (5). The light holder is fixed on the light pole (6), and the light pole is welded on the electrical box (7). Controller (8) and accumulator (9) are installed in the electric box.

[0013] attached figure 2 It is a circuit diagram, wherein the Schottky diode (10) rated current will be ≥ 2A, and the rated power of the bias resistors (11), (12), (13), (16), (20) ≥ 0.125W; the threshold resistance (14 ) rated power will be ≥ 3W; the Curie temperature of PPTC thermal element (15) i...

Abstract

The invention relates to the technical field of solar lighting, in particular to a solar phantom lamp. On the basis of the light reflection law, the inner surface of the arc face of a transparent lampshade is used as a reflection face, and continuous type multi-point focusing of an LED light source plate and pedestrians on the road surface can be achieved. When the pedestrians are away from a lamp pole by 50 to five meters, oval, round and torch-shaped dynamic bright facula images free of dazzling can successively appear on the transparent lampshade, and the facula image can be seen from the any peripheral angle. Therefore, the pole span is increased, and the investment cost is reduced. The temperature control technology is adopted, a parallel combination of a thermosensitive element and a threshold resistor can be in series connection with the positive electrode end of a storage battery, and overcharging and over-discharging of the storage battery are effectively controlled. Therefore, the rated voltage of a photovoltaic cell panel can be improved to be 1.6 times that of the storage battery, and the charging effect in the rainy day is improved. The gradient of volt-ampere characteristics of an LED chip is utilized, the voltage of the LED chip is naturally regulated and controlled, and therefore the storage battery cannot descend to the over-discharging voltage. Therefore, the solar phantom lamp meeting the all-weather unsteady illumination requirements can be achieved, and is particularly suitable for popularization of solar lamps in the township road.

Description

Technical field: [0001] The invention relates to the technical field of solar lighting, and relates to a solar phantom lamp. Background technique: [0002] Currently known solar lamps have three ways of illuminating the light source. One is the direct type, which is characterized in that: a flat LED light source board is used to set above the lamp housing, and the light passes through the lampshade of the light guide material and directly shines to the side and the bottom. There is a large difference in light intensity between near and far distances, making it difficult to meet energy-saving requirements. The second is the reflective type, which is characterized in that: a flat LED light source board is used to set it under the lamp housing, and the light is irradiated on the reflective board above, and then reflected to the side and the bottom. The luminous flux lost to the upper side is large. The third is the parallel illumination type, which is characterized in that: ...
