`
`The utility model relates to a solar lamp.
`A prior solar lamp usually consists of a solar energy conversion unit, a reflector unit, and a fixture unit.
`The solar energy conversion unit mainly comprises a solar chip, a control printed circuit board (PCB),
`cadmium sulfide (CDS) photosensitive switches, rechargeable batteries, and an LED. The reflector unit mainly
`comprises a reflector panel, a reflector cylinder, a reflector cone, and a lamp chimney. The fixture unit
`comprises a lamp cover to which the solar energy conversion unit and the reflector unit are fixed, a lamp
`holder, and other connecting pieces. The reflector cylinder of the reflector unit is usually a transparent cylinder
`whose interior and exterior walls are smooth. The defect of such a reflector cylinder is that light beams formed
`are short and discontinuous, with a low luminance.
`The utility model is intended to provide a solar lamp which can produce long and continuous light beams
`with a high luminance.
`The invention of the utility model is achieved by the following technical measures: The solar lamp
`comprises a solar energy conversion unit, a reflector unit, and a fixture unit, wherein the solar energy
`conversion unit is mounted on the lamp cover, the reflector panel is fixed in the lamp cover, the LED on the
`PCB in the solar energy conversion unit passes through the center hole in the reflector panel to reach the
`reflector cylinder, a reflector cone is equipped at the bottom of the reflector cylinder, annular saw-tooth stripes
`are set on the exterior wall of the reflector cylinder, and vertical arc stripes are set on the interior wall.
`A transparent reflector cone can additionally be equipped in the reflector cylinder to improve the
`luminance. The transparent reflector cone is suspended in the middle of the reflector cylinder.
`Arc stripes, which refract light, can be set up on the exterior wall of the lamp chimney of the reflector
`
`unit.
`
`For the utility model, a ground socket can be equipped below the lamp holder. In this case, the ground
`socket and the lamp holder are connected with a connecting tube, the ground socket sleeve is put on the lower
`end of the connecting tube, and the upper end of the connecting tube is connected to the bottom of the lamp
`holder with a key structure. At the time of installation, the solar lamp can be fixed by aligning the convex keys
`on the top of the connecting tube to the keyways at the bottom of the lamp holder, inserting the keys, and
`rotating them clockwise, without any tool.
`In addition, flash circuits can be designed for the utility model so that the lamp can automatically provide
`flashes in three different colors or lock a light color.

`
`

`

`Compared with the prior art, the utility model has the following advantages: (1) Since annular saw-tooth
`stripes are set on the exterior wall of the reflector cylinder and vertical arc stripes are set on the interior wall,
`light beams can extend to cover the entire length of the reflector cylinder and the patterns formed by crossed
`stripes on the interior and exterior walls of the reflector cylinder make light more garish. (2) The PCB of the
`utility model is set on the reflector panel, which centralizes electronic circuits to facilitate installation and
`maintenance. (3) The lamp cover in which the solar energy conversion unit is mounted can completely be
`detached from other parts so that the user can conveniently replace batteries or repair circuits. (4) The solar
`lamp can automatically provide flashes in three different colors or lock one light color.
`The following further describes the utility model in combination with the drawings and an embodiment.
`Figure 1 is an exploded view of the 3-D structure of one embodiment of the utility model.
`Figure 2 is a vertical cutaway view of the assembled embodiment in Figure 1.
`Figure 3 shows the structure of the reflector cylinder in Figure 1.
`Figure 4 is a top view of the reflector cylinder in Figure 3.
`Figure 5 is an enlarged partial view of the reflector cylinder in Figure 4.
`Figure 6 is an enlarged view of the transparent reflector cone in Figure 2.
`Figure 7 shows the circuit of the embodiment in Figure 1.
`From Figure 1 and Figure 2, it can be seen that the embodiment comprises a solar energy conversion unit,
`a reflector unit, and a fixture unit. The solar energy conversion unit comprises a solar chip (1), a control PCB
`(2), and an LED (3). The reflector unit mainly comprises a reflector panel (4), a reflector cylinder (5), an
`electroplated reflector cone (6), and a lamp chimney (7). The solar energy conversion unit is mounted on the
`lamp cover (8). A square hole is opened at the top of the lamp cover (8) to contain the solar chip (1). The solar
`chip, bonded with silica gel and packaged with resin, is characterized with sun blocking, water proofing, and
`anti-corrosion. The reflector panel (4) is fixed on to the two studs in the lamp cover (8). The LED (3) on the
`control PCB (2) passes through the center hole in the reflector panel (4) to reach the reflector cylinder (5). The
`reflector cone (6) is located at the bottom of the reflector cylinder (5). Annular saw-tooth stripes are set on the
`exterior wall of the reflector cylinder (5) and vertical arc stripes are set on the interior wall. See Figure 3
`through Figure 5. A transparent reflector cone (9) is equipped in the reflector cylinder (5). The transparent
`reflector cone is suspended in the middle of the reflector cylinder (5), as shown in Figure 2. There are
`saw-tooth stripes on the surface of the transparent reflector cone, as shown in Figure 6. Arc stripes are set up
`on the exterior wall of the lamp chimney (7) of the reflector unit of the utility model and they can refract light.
`In addition, a ground socket (12) is equipped below the lamp holder (11). The ground socket (12) and the lamp
`holder (11) are connected with a connecting tube (13). The lower end of the ground socket (12) looks like a
`spike so that it can easily be inserted into soft soil in a garden. The upper end of the ground socket (12) is put
`into the lower end of the connecting tube (13). The upper end of the connecting tube (13) is snapped into the
`bottom of the lamp holder (11) via a key structure. That is to say, two rectangular convex keys are equipped on
`the top of the connecting tube (13), and keyways which match the convex keys are equipped at the bottom of
`the lamp holder (11) accordingly. At the time of installation, the solar lamp can be fixed by aligning the
`rectangular convex keys to the keyways at the bottom of the lamp holder, inserting the keys, and rotating them
`clockwise.

`
`

`

`A circuit shown in Figure 7 is designed for the embodiment so that the solar lamp can not only
`automatically provide flashes in three different colors, but also lock one light color. The principle of operation
`is as follows: In the day, the solar chip automatically converts optical energy into electric energy, and stores it
`into two nickel-cadmium batteries via diode IN5817. As night comes, the resistance of the photo resistor
`gradually increases due to a low luminance. When the resistance increases to a certain value, triode Q4 is
`turned on and the potential of the pin of the integrated block (15) decreases. Then, triodes Q6, Q7, and Q8 are
`turned on in turn so that the LED emits, in turn, red, yellow, and green light with a super luminance. Switch
`SW1 is a power switch and switch SW2 is used to select a light color. If switch SW2 is quickly moved to
`position 2 when the LED emits red light, oscillation signals are cut off and fail to enter the integrated block. In
`this way, red light is locked. And so on, yellow or green light can be locked.
`Triodes Q3 and Q5, and capacitors C4 and C5 form an oscillator circuit. Oscillation signals are first input
`into pin 1 of switch SW2 and then into pin 14 of the IC. In the circuit, the IC type is CD4017. The operating
`voltage of the green LED is about 3.5 V, while the voltage of the power supply is about 2.5 V. Therefore, in the
`circuit, triodes Q2 and Q8 form a booster circuit to supply power to the green LED.
