Further, above-mentioned high-power LED cup light, wherein, described large-power light-emitting diodes is that power is not less than 3W, multiple photochromic light emitting diode; The outer surface of described housing is tinted, and its color is identical with the led light source glow color.

Further, above-mentioned high-power LED cup light, wherein, described lamp holder is European GU5.3, GU10 standard lamp head, perhaps ZE-27 standard screw socket; Be provided with casting coping above the cup lamp housing, it is fixed on the housing by holding screw, and optical lens is played fixation.

The utility model provides a kind of cup lamp that uses the light emitting diode of high-power, high brightness, multiple color as lighting source, has unique advantage:

(1) the utility model is a solid-state module, and is simple in structure, do not have various glass materials, annex seldom, shock-resistant, vibration resistance, safe and reliable, can save raw material, reduce product cost.By radiating groove being set, efficiently solve the LED heat dissipation problem in housing outer surface;

(2) a cup lamp is furnished with European GU5.3, GU10 standard and connects lamp holder or ZE-27 standard screw socket, can directly introduce electric main or the low-tension supply constant current is powered to LED, luminous steadily, no stroboscopic, do not contain near infrared ray and ultraviolet ray.Light-emitting window at LED is provided with optical lens, and most of rays pass through lens is launched, and forms to concentrate circular light beam, has strengthened light and has penetrated effect;

(3) compare with lighting sources such as Halogen lamp LEDs with traditional incandescent lamp, what the utility model used is cold light source, and small product size is little, in light weight, caloric value is little, and luminous efficiency is far above incandescent lamp and Halogen lamp LED, its operating voltage is low, power consumption is few, and energy-saving effect is remarkable;

(4) LED is the very little semiconductor devices of a kind of profile, when electric current can send versicolor light during by it.Mount the LED of different glow colors at cup lamp housing inner chamber, just can obtain needed versicolor cup lamp easily, further strengthened result of use, enlarged range of application.
