Description

Semi-conductor combined lamp

Technical field

The utility model relates to a kind of semiconductor lamp, particularly a kind ofly comprises one group of semi-conductor combined lamp that is installed on the semiconductor lamp on the wick.

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 luminous energy, is called light emitting diode, is also referred to as semiconductor lamp, the English LED that is called for short.Semiconductor lighting is considered to the new energy-conserving light source of illumination of 21 century, because under same brightness, semiconductor lamp power consumption only is 1/10 of ordinary incandescent lamp, 1/2 of fluorescent tube, semiconductor lamp is not only energy-conservation, also have the life-span long, volume is little, safety, environmental protection, characteristics such as non-maintaining, easy to control.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, semi-conductor combined lamp cheaply make it to have extremely important realistic meaning in more traditional lighting field alternate application.

Because the power of single semiconductor lamp is little, brightness is lower, thermal losses is bigger, should not use separately, and a plurality of semiconductor lamps are fitted together, and is designed to practical semiconductor lamp and then has broad application prospects.Semi-conductor combined lamp of the prior art adopts structure as shown in Figure 1 mostly, and one group of semiconductor lamp 7 is installed on the plate shaped wick frame 81, and lamp holder 1 connects power supply, and insulation crust 3 and Transparent lamp shade are surrounded semiconductor lamp 7.The semi-conductor combined lamp of this structure, because of not having good heat dissipation channel, heat dispersion is relatively poor, and general power is subjected to certain restriction, generally can only accomplish about 1 watt; Simultaneously, when one group of semiconductor lamp all was installed on same plane, the direction of illumination of whole semi-conductor combined lamp was also more single.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of good semi-conductor combined lamp that dispels the heat, and the existing light fixture of its irradiating angle is big.

For solving the problems of the technologies described above, the utility model semi-conductor combined lamp comprises insulation crust, wick and one group of semiconductor lamp, and semiconductor lamp is fixed on the wick, and this wick is the infundibulate wick, and semiconductor lamp is fixed on the outer surface of infundibulate wick.

Described wick is provided with louvre and radiated rib.

Comprise that also wick frame and Transparent lamp shade and described lamp holder constitute a space that surrounds described wick and described semiconductor lamp, are provided with louvre on this wick frame and the insulation crust.

The utility model is owing to adopt the infundibulate wick, and louvre is set on wick, compare with the wick of classic flat-plate shape, radiating effect greatly improves, be distributed in the surface of infundibulate wick simultaneously because of semiconductor lamp, its irradiating angle increases, and adopts the infundibulate wick also to help fixing more semiconductor lamp thereon, thereby makes powerful semi-conductor combined lamp with great heat radiation effect and illuminating effect become possibility.

Description of drawings

Fig. 1 is the structural representation of the present semi-conductor combined lamp of using always;

Fig. 2 is the structural representation of an embodiment of the utility model;

Fig. 3 is the wick schematic diagram in embodiment illustrated in fig. 2, and wick louvre shown in Fig. 3 and radiated rib are not shown in Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

The utility model is in order to overcome the deficiency that single semiconductor power is little, brightness is low, thermal losses is big of prior art, the utility model provides a kind of semi-conductor combined lamp, this semi-conductor combined lamp, demand according to lighting object and luminous flux, several semiconductor lamp Combination Design are become " secondary souce ", and can on conventional light sockets such as incandescent lamp and trichromatic energy saving lamp, use easily.

The structure of a more excellent embodiment of the utility model semi-conductor combined lamp as shown in Figures 2 and 3.In insulation crust 3, semiconductor lamp 7, driving power 4 and lamp holder 1 are connected; One infundibulate wick 8 is set, semiconductor lamp 7 is fixed on infundibulate wick 8 surfaces, the bottom of infundibulate wick 8 buckle 10 that is combined fastens, fastened by the bayonet socket of wick frame 5 above it, around wick frame 5 and in be provided with wick frame louvre 511 in the heart, the end face of insulation crust 3 is provided with shell louvre 311; Lamp holder 1, insulation crust 3,

wick frame

5 and 9 closed connections of Transparent lamp shade, this Transparent lamp shade 9 can adopt various optical lenses such as a pearl lens, and this wick frame 5 can adopt metal material nonmetal or that thermal conductivity is good to make; Wick frame louvre 511 in the wick frame 5 and the louvre 311 on the insulation crust 3 can all be provided with or all not be provided with, and also can partly be provided with.

It is big that infundibulate wick 8 can become one one end opening by an above fin merging, the infundibulate that the other end is little, and combine and realize with combination buckle 10, also can be by the wick of other being made of one of mechanical system, its bore shape can be done triangularity, square, polygonal or circle.Port footpath that the opening of infundibulate wick 8 is bigger and height can be because of the needs decisions, the length of the end that it is less also can be determined as required, by changing the concrete geometry of infundibulate wick 8, can increase and decrease its surface area and gradient, correspondingly, the number of the semiconductor lamp 7 on it is changeable also, thereby changes the power output of semi-conductor combined lamp and luminous direction.Compare with traditional plate shaped wick 81, lay more semiconductor lamp easilier on the infundibulate wick 8 that adopts in the utility model.

The diverse location of infundibulate wick 8 is provided with wick louvre 811 and radiated rib 16, the geometry of wick louvre 811 can be made Any shape, its arrangement mode also can according to circumstances change, but the length of radiated rib 16 and highly also respective change, but preferably radiated rib 16 is arranged to infundibulate wick 8 in consistent to flow path direction, can play the effect of water conservancy diversion like this.The setting of wick louvre 811 and radiated rib 16 can improve the radiating effect of semi-conductor combined lamp greatly, guarantees that the maximum service life (MSL) of semiconductor lamp 7 and minimum stream lightness reduce.

The material that it is good that infundibulate wick 8 can adopt thermal conductivity is made, as metal material.If the material thermal conductivity of infundibulate wick 8 is bad,, the semiconductor lamp fin can be set on semiconductor lamp 7 as under the situation that adopts plastics.

Consider that thermal current tends to rise, so the semi-conductor combined lamp that different occasions are used, the set-up mode of infundibulate wick 8 in semi-conductor combined lamp wherein is different, and its setting should be convenient to thermal current and rise.In the embodiment shown in Figure 2, the bigger end of infundibulate wick 8 openings is suitable for being installed in ceiling etc. and locates towards lamp holder 1; If semi-conductor combined lamp is installed on the ground, its illumination direction upwards then must be arranged to infundibulate wick 8 the bigger end of opening towards last, that is, and and toward the opposite direction of lamp holder 1.

The utility model is owing to adopt the infundibulate wick, and louvre is set on wick, compare with the wick of classic flat-plate shape, radiating effect greatly improves, be distributed in the surface of infundibulate wick simultaneously because of semiconductor lamp, its irradiating angle increases, and adopts the infundibulate wick also to help fixing more semiconductor lamp thereon, thereby makes powerful semi-conductor combined lamp with compact conformation of great heat radiation effect and illuminating effect become possibility.
