Specific embodiment

Below, with reference to accompanying drawing and specific embodiment, this utility model is described further：

As shown in figure 1, a kind of Multicolor LED lamp, including base plate 00, base plate 00 is provided with luminous zone 10, sets in luminous zone 10 There are multiple evenly distributed Multicolor lighting slabs 11, preferably, luminous zone 10 is border circular areas.

As shown in Fig. 2 Multicolor lighting slab 11 is provided with multiple luminescence chips：Red light chips 12, blue chip 13, green glow core Piece 14 and additional chips 15；In the present embodiment, additional chips 15 are white chip；But, in actual applications, can basis The demand of user arranges the luminescence chip of different colours, the luminous demand different to meet user.

With the direction of Fig. 2 as reference, on direction from top to bottom, red light chips 12, blue chip 13, green glow chip 14 The two parallel row that two is string are evenly arranged into additional chips 15；And on by direction from left to right, two on string Two luminescence chips on individual luminescence chip and another row are staggered；Red light chips 12, blue chip 13,14 and of green glow chip Additional chips 15 are evenly distributed, and the line shape between red light chips 12, blue chip 13, green glow chip 14 and additional chips 15 It is the parallelogram of acute angle in an angle, preferably angle is the rhombus of acute angle.This structure of Multicolor lighting slab 11 makes Any polychromatic light obtained on Multicolor lighting slab 11 can be thoroughly mixed, and without there is colour cast, polarisation and hot spot uneven phenomenon, make Obtain white light photochromic pure, hot spot after lens or reflector receive light uniform, reduce light loss；And light-source structure is compact, Face shaping is light and handy, is easily installed, and simplifies finished product making work, saves product cost, lifts down-stream enterprise's product competitiveness.

Multicolor lighting slab 11 is provided with and is respectively used to and red light chips 12, blue chip 13, green glow chip 14 and additional wick HONGGUANG negative terminal pad 012, green glow negative terminal pad 023, blue light negative terminal pad 034 and accessory negative that the negative pole correspondence of piece 15 is welded Pad 045, and it is provided with the positive pole being respectively used to red light chips 12, blue chip 13, green glow chip 14 and additional chips 15 HONGGUANG positive terminal pad 052, green glow positive terminal pad 053, blue light positive terminal pad 054 and accessory positive pad 055 that correspondence is welded.By The Multicolor lighting slab 11 that four kinds of difference photochromic ground luminescence chips are constituted, can cause luminous zone 10 the light mixture of colours it is more equal It is even, so as to can further avoid the occurrence of colour cast, polarisation and hot spot uneven phenomenon, further so that white light passes through lens Or after reflector receipts light, photochromic pure, hot spot is uniform, further reduces the loss of light.

The total pad 01 of HONGGUANG negative pole, the total pad 02 of green glow negative pole, the total pad 03 of blue light negative pole, additional is additionally provided with base plate 00 The total pad 04 of negative pole and public positive terminal pad 05；

The HONGGUANG negative terminal pad 012 of all Multicolor lighting slabs 11 in luminous zone 10 is connected with the total pad of HONGGUANG negative pole 01 Connect, the green glow negative terminal pad 023 of all Multicolor lighting slabs 11 is connected with the total pad of green glow negative pole 02, all Multicolor lighting slabs 11 Blue light negative terminal pad 034 be connected with the total pad of blue light negative pole 03, the accessory negative pad 045 of all Multicolor lighting slabs 11 is equal It is connected with the total pad of accessory negative 04.The HONGGUANG positive terminal pad 052 of all Multicolor lighting slabs 11, green glow positive terminal pad 053, blue light Positive terminal pad 054 and accessory positive pad 055 are connected with public positive terminal pad 05.

It is provided with multiple evenly distributed and is formed to the edge of luminous zone 10 from the inside center of luminous zone 10 in luminous zone 10 The Multicolor lighting slab 11 of multiple structure, and in luminous zone 10, a great circle and one are drawn by the center of circle of the center of luminous zone 10 Roundlet, the quantity of the Multicolor lighting slab 11 on the edge of great circle is more than the Multicolor lighting slab 11 on the edge of roundlet Quantity；The light that LED luminescence chips send can be caused more uniform using such layout, so as to further avoid the occurrence of partially Color, polarisation and hot spot uneven phenomenon, further such that white light photochromic pure, hot spot after lens or reflector receive light is equal It is even, light loss is further reduced, and provides many to increase LED luminescence chips quantity by the quantity for increasing Multicolor lighting slab 11 Power selection is planted, the various occasions for needing color desktop and power requirement are suitable for.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of this utility model claim Within the scope of.
