Description

A kind of wick and the searchlight that contains this wick

Technical field

The utility model belongs to a kind of wick of light fixture, relates to the improvement of light fixture wick structure, more specifically, is a kind of wick for the lighting use that is made of a plurality of tiny light emitting sources.

Background technology

Traditionally, the LED luminous tube has advantages such as low energy consumption, high light efficiency, is subjected to people's attention.Particularly in the energy comparatively nervous today, power saving is constantly brought into schedule.Vast producer has been noted that how to develop the LED luminous tube is applied in the illumination in the daily life.Because single LED luminous tube, power is too little, can't be suitable for the requirement of illumination, thereby these LED luminous tubes must be assembled.When the LED luminous tube is assembled, the LED luminous tube fixing problem that how to distribute can appear, so that the LED luminous tube that gathers is brought into play better illuminating effect and the convenient problem that connects.At present, the modes that adopt plane distribution are used in the set of LED luminous tube more, and not only illuminating effect is relatively poor, and couple together also inconvenient.

Summary of the invention

The purpose of this utility model is that a kind of wick will be provided, and this wick is assembled by many LED luminous tubes and formed, and has the mounting structure that distributes preferably, it can to around emit beam, can reach to each orientation illumination, and be linked and packed and also make things convenient for.

The purpose of this utility model also is to provide a kind of searchlight that contains above-mentioned wick, and this searchlight utilizes the structure of above-mentioned wick, by self is transformed, thereby obtains to have the searchlight of better heat dissipation effect.

Its purpose is realized by following scheme:

A kind of wick comprises the cylinder of being made by metallic copper, it is characterized in that, cylinder is equipped with aluminium base on each side, and printed circuit is arranged on the aluminium base, and is equipped with some wafers on it; The first end of cylinder, metal end is installed, metal end is stamped the some crooked gripper that is formed by body downwards, and body center has through hole and disposes screw, can pass the metal end through hole and fix by screw with the cylinder first end, and be close on the polarity of aluminium base printed circuit by the crooked gripper of metal end, make metal end become an electrode; The second end of cylinder, stretch out from its end face and to form less cylinder, as erection column, the metal end ring is housed on the erection column, the metal end ring has the some crooked gripper that is upwards formed by body, and its body center has than large through-hole, be with central authorities in the metal end ring and have the insulation spacer of through hole, the center through hole that can make the erection column of cylinder pass metal end ring and insulation spacer, and metal end ring and cylinder are realized that electricity isolates by insulation spacer, some crooked gripper by the metal end ring is close on another polarity of aluminium base printed circuit, can make the metal end ring become another electrode.

Like this, the some wafers on the aluminium base, as long as wafer is contained in the position, hole of printed circuit, the structure that can be laid in advance by printed circuit can make them be electrically connected.

In addition,, when they are luminous, can emit beam, have characteristics to each orientation illumination to all directions because each side of cylinder is distributed with row's wafer.

Moreover, because the cylinder two ends are provided with metal end and metal end ring, metal end and metal end ring provide crooked gripper for each side, the positive and negative electrode performance of the printed circuit on each side enough is unified separately, and the fit structure of metal end, metal end ring and cylinder, crooked gripper and aluminium base printed circuit are close to, are made the connection degree of electricity between them obtain reinforcement.

Also have, the polarity of metal end can be extended, it is caused the center through hole of metal end ring and stretch out, can make positive and negative the two poles of the earth be positioned at same end, like this, install to connect and also will become more convenient by cylinder.

Thus obtained wick has advantage energy-conservation, that assembling is easy, connection is reliable and easy to use.

For realizing second purpose of the present utility model, adopt following scheme:

A kind of searchlight, comprise pedestal and reflector, be characterized in, include above-mentioned wick, described wick is positioned at reflector, is contained on the pedestal, between the metal end ring of pedestal and described wick wiring board is arranged, wiring board is connected with the electrode of described wick, and the Kong Weiyu that the erection column of described wick passes wiring board is positioned at the heat radiation aluminium block contact of pedestal.

Can obtain a kind of searchlight thus, the light source of this searchlight comes from the LED luminous tube, and the heating of components and parts can be derived rapidly to the bottom by cylinder and heat radiation aluminium block on the wiring board.
