Abstract
The utility model relates to an adjustable, high-display and high-lighting-effect COB lamp which comprises a display index adjustable lamp panel circuit and a display index adjustable power circuit. The display index adjustable lamp panel circuit comprises a white light input end, a white light output end, a red light input end and a red light output end or a yellow light input end and a yellow light output end or a green light input end and a green light output end. The display index adjustable power circuit comprises an EMC filtering lightning protection circuit, a rectifying and filtering circuit, a master control circuit, an isolation transformer circuit, an adjustable control circuit and a constant-current control circuit. The display index can be adjusted from 70 to 90 without adding red powder to fluorescent powder, and the lighting effect can reach 130 LM/W to 160 LM/W. Color shifting is slightly influenced, and almost all the lighting needs of indoor and outdoor lighting and fresh jewelry and the like are facilitated. The added yellow light is applied to an LED street lamp, the transmitting capacity of the LED street lamp can be increased, and the defect that the transmitting capacity of an existing street lamp is insufficient is overcome.
Description
Technical field
The utility model relates to a kind of light fixture, and especially a kind of adjustable height is aobvious, high light efficiency COB light fixture.
Background technology
In COB lamp bead seal fills at present, all to adopt blue chip to be encapsulated in ceramic substrate, aluminium base or copper base by string mode also, this kind of encapsulation scheme wants to obtain the high aobvious lamp pearl referring to, just must in fluorescent material, add rouge and powder, cause so the aobvious finger of whole lamp to be up, but light efficiency is lower again, and its aobvious finger of generally accomplishing high light efficiency (130LM/W) is in 60-70 left and right and fixes, although this kind of way can meet the demand of outdoor lighting and brightening, be not well positioned to meet the lighting demands such as indoor and outdoor lighting light fixture demand and fresh jewelry.
