Description

Water drift color changing lamp

                      

The utility model relates to a decorative lighting lamp, which is a lamp powered by a solar rechargeable battery, illuminated by a semiconductor light-emitting tube, variable in color and capable of floating in water, referred to as a color-changing floating lamp.

Background technique

With the improvement of people's living standards, higher requirements are placed on cultural and spiritual life. Some folk customs and habits with traditional cultural colors in the past have not only been restored and protected, but also joined with modern material civilization. For example, the folks have the custom of making lanterns on the Lantern Festival, and watching the lanterns and the moon on the Mid-Autumn Festival in August. In the past, lanterns were generally lit with candles, whose brightness and windproof performance were far inferior to those of today's electric lights, and of course it was even less likely to change color. In modern society, in activities such as Lantern Festivals, all kinds of lanterns are mostly electric lights, fixed hanging ones use AC power supply, and portable portable ones generally use dry batteries. Colorful lanterns add joy to festivals or celebrations. atmosphere. But, what still have a kind of single small lantern that floats in water is candle, and its defective that can't resist wind is conspicuous. If it is replaced by an electric lamp, the requirements for sealing and insulation are higher. With alternating current, it is obviously impossible to drag wires outside; with dry batteries, the seal will be destroyed due to frequent replacement. In view of this, designing a kind of color-changing water floating lamp that utilizes solar rechargeable battery to supply power and can float in water for a long time will make this custom among the people improve to a new realm.

Contents of utility model

The technical problem to be solved by the utility model is to provide the society with a wind-resistant color lamp that can float in water for a long time and can change color, so as to replace the non-wind-resistant candles floating in water.

The technical scheme of the utility model to solve the technical problem is: a semiconductor diode light-emitting lighting lamp is arranged in a sealed transparent or translucent spherical lampshade. This kind of lighting lamp is called an LED lighting lamp in the industry. The lighting mechanism of the LED lighting technology is Energy conversion of PN junction carriers in semiconductor wafers. Its power supply is supplied by the rechargeable battery of the solar panel, and the color-changing light is supported and controlled by a dedicated circuit board. The color-changing float lamp of the utility model includes an upper outer cover, a solar photosensitive plate, a booster circuit board, an upper reflector, an inner lampshade, a lower reflector, a light-emitting diode, a color-changing circuit board, and a lower outer cover from top to bottom. In addition, a rechargeable battery and a photosensitive resistor functioning as a switch are connected in series in the circuit. The solar photosensitive plate collects solar energy and generates electromotive force, but the electromotive force generated by it is not enough to make the diode emit light, so the voltage must be raised to a rated value by a booster circuit. If the current intensity flowing from the anode to the cathode of the light-emitting diode is changed, the semiconductor crystal will emit light of different colors from ultraviolet to infrared. The on-off of the circuit is controlled by a photoresistor. When the light is dim at night, the photoresistor turns on the circuit and the lamp is lit; Charging batteries.

The utility model is a perfect combination of solar energy utilization technology and LED lighting technology. It has beautiful appearance, good airtightness, no wires to drag, no need to replace batteries, can float in water for a long time, and can control discoloration, it is an ideal product to replace windproof candles floating in water. At the same time, it can also be used as decoration and embellishment of parks and villa gardens, and large ones can also be used as navigation lights for waterways.

Detailed ways

As shown in each part in Fig. 1, the utility model color-changing floating lamp consists of an upper outer cover 1, a solar photosensitive plate 2, a boost circuit board 3, an upper reflector 4, an inner lampshade 5, a lower reflector 6, a light-emitting diode 7, The discoloration circuit board 8 and the lower outer cover 9 are assembled sequentially and then sealed. The solar photosensitive plate 2 is on the top in the cover, so as to be beneficial to fully receive solar energy. The booster circuit board 3 is close to the solar photosensitive plate 2 to reduce power loss. At least three light-emitting diodes 7 are directly welded on the color-changing circuit board 8. Through the program control of the color-changing circuit board 8, the strength of the current changes, and the different colored lights emitted by each light-emitting diode 7 can be synthesized to produce from ultraviolet to infrared. Various colored lights, which can change the color of the colored lights. After dawn in the daytime, the photoresistor turns off the circuit, and the solar photosensitive plate 2 receives solar energy and charges the battery. When the light is dim at night, the photoresistor turns on the circuit, the light-emitting diode is lighted, and the color change is controlled by the color-changing circuit board. Use sealing material to seal between upper outer cover 1 and lower outer cover 9, never leak. At the same time, due to the long life of the LDE lighting lamp, and the use of solar energy to charge repeatedly, there is no need to replace the battery, so it can float in the water for a long time.
