Embodiment 1

[0026] See figure 1 , figure 2 and Figure 5 As shown: a color-changing LED tube spotlight, including a lamp body 10, an LED lamp and an infrared sensor 11 are installed in the lamp body 10. A lamp body pin 17 is arranged at the bottom of the lamp body, and the lamp body pin 17 can be matched with a power supply. The LED lamp is connected to the lamp body pin 17 through a circuit and is electrically connected to the power supply through it. Described LED light comprises red light LED light 12, blue light LED light 13 and green light LED light 14, and infrared sensor can cooperate with external signal emitter, adjusts its interior by receiving the signal transmitted by signal emitter. Code information, so as to control the changes in the intensity of the above three LED lights, allowing them to combine various tones. The red LED lamp 12, the blue LED lamp 13 and the green LED lamp 14 are respectively fixed in the mounting holes 151 of the reflector cup 15 and their central...

Embodiment 2

[0031] See image 3 , Figure 4 and Figure 5 As shown, the difference from the first embodiment is that six white LED lamps 16 are installed inside the lamp body 10 and around the outer surface of the reflective cup 15 . The light spot projected by the white LED lamp 16 from the focusing lens can wrap the circular light spot inside it, increasing the focusing effect of the circular light spot.

[0032] The LED tube spotlight of the present invention vertically irradiates on a plane three meters away, and a colored circular spot with a diameter of about 40 cm appears. The boundary of the light spot is clear, the outline is circular, and the color can be modulated arbitrarily. The principle is: the reflective centers of the red, green and blue LEDs are respectively placed on the focal points of the three reflectors, and the light generated by the LEDs is reflected twice on the inner surface of the reflector cup and is aligned along the central axis of the reflector cup. Whe...

Abstract

The invention discloses a color-changing LED (Light-Emitting Diode) tube-shaped spotlight comprising a lamp body. The lamp body is internally provided with LED lamps and an infrared sensor, the infrared sensor controls the strength change of light rays of the LED lamps by a signal emitter, and the LED lamps are connected with a power source by circuits. The LED lamps comprise red LED lamps, blue LED lamps and green LED lamps, which are respectively fixed in mounting holes of a light reflecting cup, the central axial lines the LED lamps are mutually parallel, and the focuses of the LED lamps are located on cross points of the central axial lines and a mounting hole bottom. The light rays from the LED lamps are secondly refracted on the inner surface of the light reflecting cup and then emitted out in a forward direction in parallel to the central axis of the light reflecting cup so as to form a circular facula on a projection place. The invention has simple structure, the infrared sensor can control the strength change of the light rays of the LED lamps to make the LED lamps have various color change; and each LED lamp can form a circular facula with basically superposed central points on the projection place.

Description

technical field [0001] The invention relates to the technical field of spotlights, in particular to a color-changing LED (Light Emitting Diode, light emitting diode) downlight. Background technique [0002] The purpose of the spotlight is like a flashlight. It is made of metal materials with good heat dissipation performance. It is made of ultra-high-brightness LED lights of various colors, which are combined after testing and aging. Spotlights are generally divided into downlights and track spotlights. [0003] The downlight can be installed on the ceiling, above the head of the bed, in the cabinet, and can also be hung, floored, and suspended. It is divided into two types: full Tibetan and half Tibetan. The characteristic of the downlight is that the light source is partially irradiated and freely scattered from top to bottom, and the light source is closed in the lampshade. Slot down lights and down wall lights, etc., can be installed in porch, living room and bedroom r...
