Background technology
The semi-conductor electricity light source is a kind of electric light source that does not have filament, is a kind of luminescent device that directly electric energy is converted into visible light, is called light emitting diode, is also referred to as semiconductor lamp, the English LED that is called for short.It is low that the semiconductor lighting technology has operating voltage, and power consumption is little, advantage such as luminous efficiency height, life-span are long, easy to control.Semiconductor lamp power consumption only is 1/10 of ordinary incandescent lamp, 1/2 of fluorescent tube, but its life-span be 10 times of fluorescent lamp, 100 times of incandescent lamp, aspect environmental protection, also avoided fluorescent tube to break and overflowed the secondary pollution of mercury.Semiconductor lamp has the very big potentiality of alternative traditional lighting light source as the novel illumination light source.Therefore, research and development high-tech, high efficiency, semiconductor lamp combined lamps cheaply make it in more traditional lighting field alternate application early, have extremely important realistic meaning.
Because the power of single semiconductor lamp is little, brightness is lower, should not use separately.According to the demand of lighting object and luminous flux, the semiconductor lamp with several semiconductor lamp Combination Design one-tenth " secondary souce " has broad application prospects.Semiconductor lamp combined lamps of the prior art adopts structure as shown in Figure 1 mostly, and one group of semiconductor lamp 8 is installed on the pcb board of insulation crust 2 the insides, and lamp holder 1 connects power supply, and insulation crust 2 and Transparent lamp shade 9 are surrounded semiconductor lamp 8.The semiconductor lamp combined lamps of this structure, because of not having good heat dissipation channel, heat dispersion is relatively poor, and general power is subjected to certain restriction.Simultaneously, one group of semiconductor lamp all is installed on same plane, and the irradiation angle that its semiconductor lamp sends is fixed.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of light source and the isolated semiconductor lamp combined lamps of driver thermal source, and the existing light fixture of the irradiating angle of its light source is changeable.
For solving the problems of the technologies described above, the utility model semiconductor lamp combined lamps, comprise insulation crust, driving power, heat insulation, radiator and one group of semiconductor lamp, this radiator is the infundibulate radiator, semiconductor lamp is fixed on the bottom surface of infundibulate radiator, and semiconductor lamp is surrounded by Transparent lamp shade and sealing ring.The infundibulate radiator is provided with entrance hole and connecting hole, and is provided with radiated rib on its outer surface.Heat insulation bottom surface is provided with long column, short column, fairlead and fixing hole.
The utility model is owing to adopt the infundibulate radiator, and be provided with radiated rib on its outer surface, isolated with driving power again, compare with the light fixture of classic flat-plate shape, radiating effect greatly improves, be distributed on the infundibulate radiator bottom surface because of more high power semi-conductor lamp simultaneously, its irradiating angle is also changeable, thereby make to have simple in structure, heat radiation and the good semiconductor lamp combined lamps of illuminating effect becomes possibility, and can be widely used in multiple fields such as general illumination and special lighting.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The structure of a more excellent embodiment of the utility model semiconductor lamp combined lamps as shown in Figure 2.In insulation crust 2, comprise driving power 3 and lamp holder 1, and combine closely with heat insulation 4 and infundibulate radiator 6, semiconductor lamp 8 is fixed on the bottom surface of infundibulate radiator 6, Transparent lamp shade 9 and sealing ring 7 and 6 closed connections of infundibulate radiator, this Transparent lamp shade 9 can adopt optical lens or plane spray of molten steel glass.
The shape of infundibulate radiator 6 is that one one end opening is big, the infundibulate that the other end is little.Applied in reverse of the present invention, promptly go up central opening little (entrance hole 601), the bottom surface opening is big, be provided with entrance hole 601 in bottom center, this entrance hole 601 also can depart from the center and be provided with, and connecting hole 602 can depart from the center and be provided with more than one, also can be provided with near the center, the bottom surface of this infundibulate radiator 6 can make horizontal plane, also can make to center or the tapered plane that tilts to periphery.
That the bigbore shape of infundibulate radiator can be done is circular, square, rectangle or polygonal, and is provided with radiated rib 5 and 10 on its outer surface.This infundibulate radiator, according to watt level, can adopt extrusion section bar radiator or metal shell shape, when adopting the metal shell shape, on surface of shell, can be provided with rule or random concave-convex curved surface, and be used with substrate that has semiconductor lamp 8 or wick.With the increase of infundibulate radiator bore, can append new radiated rib, and mechanically or the die casting mode be integral.Thereby with the heat that high power light source produces in the course of the work, conduction is timely distributed, and guarantees the maximum service life (MSL) and the decay that minimizes luminous flux of semiconductor lamp 8.
Be provided with long column 403 and short column 404 heat insulation 4 bottom surface, have fixing hole 402 for 403 li at long column, open fairlead 401 for 404 li at short column, and combine closely into hanging structure mutually with infundibulate radiator 6, so that the heat in radiated rib 5 and 10 carries out free convection rapidly in air.When the extraordinary light fixture of designing high-power, small size, short time illumination, can be at heat insulation 4 the inside installation shaft flow fan, and have exhaust vent in its bottom surface, infundibulate radiator 6 is carried out air blast cooling.Heat insulation 4 geometry can change according to the variation of the geometry of infundibulate radiator 6 and insulation crust 2, and heat insulation 4 usefulness material adiabatic and good insulation preformance made.
The utility model semiconductor lamp combined lamps, in the time of need being used with traditional plug, driving power 3 in the insulation crust 2 is electrically connected with semiconductor lamp 8 and lamp holder 1, need be with traditional plug, as the needs ceiling, when using lead-in wire fixedly on wall or other lamp brackets, available lead-in wire fixed mount is replaced the lamp holder 1 on insulation crust 2, according to the heat radiation requirement, insulation crust 2 also can be made of the good metal material of thermal conductivity, and the metal shell surface is provided with rule or random concave-convex curved surface, increase its area of dissipation thus, produce heat when high-power so that conduction is timely distributed by driving power 3.
