The specific embodiment
Followingly the utility model is further described with reference to accompanying drawing:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4; The utility model is the wide luminous intensity distribution PAR of an a kind of LED lamp; Comprise heat radiation lamp body 1, surperficial retainer ring 2, be placed on the light source board 3 of heat radiation lamp body 1 bottom; Cover the bottom reflection paper 4 on the light source board 3; Be fitted in the offside reflection paper 5 on the heat radiation lamp body 1 side conical surface, be placed on heat radiation lamp body 1 surface step 12 and by surperficial retainer ring 2 push down and lock its axial location diffuser plate 6, be installed in the power panel 7 that the grooving by both sides in the power source cavity and bottom in heat radiation lamp body 1 back side power source cavity blocks, and be installed in the base 8 on interior three erection columns 17 of heat radiation lamp body power source cavity.Said heat radiation lamp body 1 bottom is provided with a ring-shaped step 11, and said bottom reflection paper 4 is pushed down its edge through offside reflection paper 5 and is fixed on the said ring-shaped step 11.There is the surface step 12 of placing diffuser plate 6 on said heat radiation lamp body 1 surface; On surface step 12, also be provided with the raised step 13 identical with the diffuser plate height; And three recessed downwards cylindrical fixing slot 14 that are uniformly distributed with, said diffuser plate by the medial surface of raised step 13 confirm its radially the position and in fixing slot 14 places leaving certain gaps uncovered by the economic plan.Three protruding column shape steps 21 on the said surperficial retainer ring 2 insert the installing and locating hole slot 14 on the thermal louver surface step 12 when installing; Radially cooperates with the lateral surface of the surface step 13 of heat radiation lamp body 1 and confirm, at last by the cylindrical step 21 of the fixing slot 14 of screw through heat radiation lamp body 1 and surperficial retainer ring 2 fixedly diffuser plate 6 and surperficial retainer ring 2 (like Fig. 4) by the step side 22 of surperficial retainer ring 2; Said heat radiation lamp body 1 back side power source cavity madial wall has the trapezoidal mounting groove 15 of two symmetries; And in power source cavity bottom grooving is connected; Trapezoidal mounting groove 15 oral area width are bigger, and are less near the at width, can it be blocked fixing (like Fig. 3) when power panel 7 inserts when installing from top to bottom; Grow and the hole that is lower than on three column type steps 17 that are uniformly distributed with of sidewall is the installing and locating hole (like Fig. 3) of base 8 along sidewall in the power source cavity at said heat radiation lamp body 1 back side.
The light source board 3 that install said heat radiation lamp body 1 bottom to the surface step 12 that diffuser plate 6 is installed has certain distance, and the LED of different colours can be set on the said light source board.
Because step to the light fixture outer surface of the light source of adorning has certain distance; Can be so that light goes out to form wide luminous intensity distribution via the reflecting paper reflection after sending from light source board; And can use the LED of different colours to make its natural mixed light in reflection cavity on the light source board; Make reflection cavity and mixed light chamber unite two into one like this, for high-color rendering provides the basis; Secondly, the diffuser plate of the light that is reflected by reflecting paper through high mist degree, high transmission rate can prevent dazzle (with using lens and comparing).
The above embodiment that lifts is not only breaking away from the creation spirit scope of the utility model by the utility model conveniently to explain, is familiar with any simple covert and modification that the personage did of this technology, must be contained in the rights protection scope of the utility model.
