Embodiment Construction
[0026] Below in conjunction with accompanying drawing, structure and working process of the present invention will be further described.
[0027] Such as figure 1 As shown, a patch LED lamp with adjustable color temperature includes a bracket bowl, a yellow chip 1, a blue chip 2, and a red chip 3, wherein the yellow chip 1, the blue chip 2, and the red chip 3 all include P Pole and N pole, yellow chip 1, blue chip 2, red chip 3 are arranged at intervals in the bracket bowl, blue chip 2 is located on the center line of the bowl, yellow chip 1, red chip 3 and blue chip 2 The center distances are equal, and three pairs of pins are symmetrically arranged outside the bracket bowl in turn. The three pairs of pins include positive pins and negative pins, and the three pairs of pins are connected to yellow chip 1, blue chip 2, and red chip 3 respectively. Corresponding settings, the yellow chip 1 and the first pair of pins form the first circuit, the blue chip 2 and the second pair o...

The invention discloses an SMD LED lamp with adjustable color temperature. The lamp comprises a bracket bowl cup, yellow chips, blue chips and red chips, wherein the yellow chips, the blue chips and the red chips are sequentially arranged in the bowl cup; the areas of the blue chips are greater than those of the red chips, and the areas of the red chips are greater than those of the yellow chips; each of a first loop, a second loop and a third loop comprises pin conductive regions; the area of the pin conductive region of the second loop is larger than that of the pin conductive region of the third loop, and the area of the pin conductive region of the third loop is larger than that of the pin conductive region of the first loop; one blue chip with high power, one red chip with medium power and one yellow chip with low power are integrated and sealed to obtain the white-light LED with high light flux and high color rendering property in a fluorescent powder stimulation manner.
Description
technical field [0001] The invention belongs to the field of LED applications, in particular to a patch LED lamp with adjustable color temperature. Background technique [0002] LED is the abbreviation of light emitting diode in English. Its basic structure is a piece of electroluminescent semiconductor material, which is placed on a shelf with leads, and then sealed with epoxy resin around it to protect the inner core wire. role, so the shock resistance of LED is good. [0003] Color temperature of the light source: People use the absolute temperature of a complete radiator equal to or close to the color temperature of the light source to describe the color surface of the light source (the color seen when the human eye directly observes the light source), also known as the color temperature of the light source. Color temperature is expressed in absolute temperature K. Different color temperatures will cause people to respond differently emotionally. We generally divide th...
