Description
Technical field
The invention belongs to the photoelectron technology application, a kind of specifically LED ball lamp with high light efficiency high color rendering index (CRI) light source module.
Background technology
Led light source is just obtaining increasingly extensive application with its unique advantages, and replacing incandescent lamp and electricity-saving lamp becomes the illumination main flow.Good lighting source, not only light efficiency wants high, also good color restoration capability will be arranged, and promptly colour rendering index wants high.The colour rendering index of incandescent lamp can reach 100, and colour rendering is best, but because of light efficiency is too low by various countries' legislation forbidding, promptly forbids producing; And the colour rendering index of high-pressure mercury lamp is low, and the color rendition distortion though light efficiency up to 120lm/W, also can only be used for outdoor road lighting on a small quantity, can't enter the general room outdoor lighting, and therefore, the Novel LED light source application popularization also needs to improve colour rendering index.
At present, the method for LED generation white light has two kinds: 1, the principle of three primary colours: with red, green, blue three color contamination synthesize white lights.Control red, green, blue three look different proportions respectively, can produce all colours that comprises white light, but the drive circuit complexity is mainly used in colorful display screen and decorative lighting, is not suitable for general lighting; 2, be mixed into white light with blue-ray LED+yellow fluorescent powder, this kind method and technology maturation, drive simple, and light efficiency has surpassed 120lm/W, reach the practicability stage, the application at the indoor and outdoor lighting field at present surpasses 40% annual growth, is the mainstream technology of producing white light LEDs, but that its weak point is a colour rendering index is on the low side.In addition, with lacking ruddiness in the white light that blue-ray LED+yellow fluorescent powder produced, R9 in the special colour rendering index (to the color restoration capability of redness) is negative value, its colour rendering index Ra is generally between 65-75, this defective makes common white light LEDs be difficult to enter the market of high-quality requirement, satisfy this regulation, needs to adopt day extraordinary yellow fluorescent powder of inferior chemical patent technology production, but this white light LEDs price also is the several times of common white light LEDs, and ordinary consumer is difficult to accept.
China national Department of Intellectual Property discloses the patent of " a kind of LED bulb lamp with high color rendering index and high illumination efficiency " by name in 2010-10-17, by being combined to form led light source by the white light LEDs of blue-light excited YAG fluorescent material, the white light LEDs and the common red-light LED of adding nitride red fluorescent powder, on colour rendering index and light efficiency, all obtain comparatively obvious effects, but the preparation difficulty of nitride red fluorescent powder is difficult to control on the cost; And also mention by the white light LEDs manufacturing cost of blue-light excited YAG fluorescent material higherly above,, in fact can not effectively control its cost, and the increase of light source kind is returned manufacturing process and brought certain difficulty though common red-light LED has been arranged by way of compensation.
Summary of the invention
Problem to be solved by this invention just provides a kind of LED ball lamp with high light efficiency high color rendering index (CRI) light source module, solves colour rendering index and the two shortcoming that is difficult to take into account of light efficiency of led light source in the prior art, and controls its manufacturing cost.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of LED ball lamp with high light efficiency high color rendering index (CRI) light source module, comprise the radiating shell that is built-in with driver and LED illuminating module, the radiating shell front end is provided with the expansion light shield, the radiating shell afterbody is provided with lamp holder, it is characterized in that: described LED illuminating module comprises installs template and is located at white light LEDs annular array and the red-light LED annular array of installing on the template, and the white light LEDs annular array is distributed in red-light LED annular array periphery.
Further, described white light LEDs annular array and red-light LED annular array are the rotational symmetry structure with same pivot, wherein the quantitative proportion between white light LEDs and the red-light LED is 2: 1, and each red-light LED correspondence on bearing of trend radially is distributed with a white light LEDs.Make its luminous mixed effect even, avoid producing bright-colored color lump.
Further, described white light LEDs quantity is 8-20, and red-light LED quantity is 4-10.
Further, described installation template is aluminium base or pcb board.
Beneficial effect of the present invention:
The present invention need not to adopt specific, expensive led light source, only make up the colour rendering index and the light efficiency that just can effectively promote led light source with low price, common white light LEDs and red-light LED, its special colour rendering index R9 by negative value become on the occasion of, not only simplify fitting structure and manufacturing process thereof, and when improving LED light fixture quality, significantly reduced cost again;
Adopt the LED illuminating module after the above-mentioned rotation symmetric arrays form, having guaranteed that colour rendering index and light efficiency all have on the basis of lifting, make its luminous mixed effect more even, avoid producing bright-colored color lump, the lamp lighting effect further;
Proposition of the present invention helps the application popularization of white light LEDs in the general lighting field, and energy-saving and emission-reduction, environmental protection are had good positive effect.
