Abstract

The utility model discloses a multiple lamp. The cores of light emitting diodes are used for ranking an array and sealed into a whole. The structure of the multiple lamp is similar to the compound eye of an insect. Because the cores of the light emitting diodes of the multiple lamp are used as a light emitting source, the multiple lamp overcomes the defects of the existing signal lamp of short service life, poor aseismatic performance, poor resistance to pressure, etc. The utility model can be widely used as the signal lamp, a decorative lamp and an illuminating lamp.

Description

Multiple lamp

The utility model belongs to lamp source.In the structure of signal lamp (as automobile tail light, electrical equipment indicator lamp), adopt incandescent lamp or neon lamp as light source usually, coloured or colourless astigmatic transparent material is the structure of face shield.Because incandescent lamp, neon lamp all are to be principle according to heat filament to obtain maximum illumination effect, and the illumination effect controllability is poor.Thereby, in the utilization of the signal lamp of reality, exist weak point in service life, complex structure, moulding simply, drawback such as shock resistance crushing resistance difference, make signal lamp institute utilization scope and development be greatly limited.

The purpose of this utility model provides a kind of novel lamp light source, can use in signal lamp and partial illumination light fixture, at aspects such as life-span, moulding, antidetonation crushing resistances breakthrough progress is arranged.

The structure of compound lamp is similar to the compound eye of insect, and it comprises following components:

1. the sub-lamp of compound lamp (be equivalent to insect son eye): sub-lamp is the light-emitting diodes tube core, is light emitting source independently, and its luminous mechanism is identical with common light emitting diode.The sub-lamp of compound lamp has a plurality of, and the number of sub-lamp is decided on the different illumination effects that require.

2. the lamp body of compound lamp: constitute by a kind of coloured or colourless light transmissive material (as plastics, lucite and glass etc.).The front of lamp body produces illumination effect.Lamp body not only is used for fixing each sub-lamp, circuit connection and provides fixing to light fixture, and various moulding can also be arranged, and utilizes and regulate translucent effect and color to satisfy different signals or lighting requirement.

3. the internal circuit of compound lamp connects: the power supply of compound lamp (two ends) is provided by the outside.Each sub-lamp constitutes the loop by lead or printed circuit board (PCB).The power supply in this loop has two kinds of connected modes, i.e. direct current mode and exchange way.The direct current mode is formed by regulating resistance and sub-circuit for lamp network, and sub-circuit for lamp network is formed in parallel by some identical sub-lamp branch roads, and sub-lamp branch road then is composed in series to the plurality of sub lamp by one, and the number of sub-series lamp is definite by sub-light working voltage and input voltage.The number of sub-lamp branch road is decided by illumination effect.Above-mentioned adjusting resistance is used for limiting and controlling the electric current of network, and it can be in series with sub-circuit for lamp network, also can be in series with each sub-lamp branch road, can cancel in the occasion that does not need this control.Exchange way is to utilize diode bridge rectifier circuit or other rectification circuit that alternating current is become direct current, and then and the circuit of above-mentioned direct current mode be in series.

4. the power supply lead wire of compound lamp: the power supply lead wire of compound lamp is two common end power connectors.

The sub-lamp of all of compound lamp is arranged in one plane or on the curved surface according to certain rules, thereby forms a sub-lamp array of two dimension.Sub-lamp array can be square formation, rectangular matrix, triangle battle array, hexagonal battle array, honeycomb battle array, concentric circles battle array etc.Sub-lamp array becomes an integral body by light transmissive material encapsulation (Shooting Technique or other, and guarantee the illumination effect of filament in the lamp body front).The internal circuit of sub-lamp connects and can carry out in lamp body, also the circuit pin of sub-lamp can be stretched out the lamp body outside, carries out circuit again and connects.The power supply of compound lamp is drawn with the fixing of lamp can adopt existing mode.

Compound lamp construction features: the as a whole structural member of compound lamp (comprising sub-lamp, lamp body, power connection and mechanical fixation etc.); Its illumination effect is a plane or curved surface; Its power connection (two ends) directly joins with power supply (direct current or exchange).

Compound lamp has following advantage:

Compound lamp is inherited lifetime of LED long (more than 5 years) fully, and the antidetonation crushing resistance is good, and plasticity waits outstanding advantage (than incandescent lamp etc.) by force.In addition, compound lamp utilizes the principle of stacking of light dexterously, makes its illumination effect serialization, and efficient does not reduce.This has obviously brought great usefulness, promptly within the specific limits can be by the quantity that increases or reduce sub-lamp to satisfy various demands.

Compound lamp can use the aspect that also can obtain tremendous development to have:

1. signal lamp, as the motor vehicles signal lamp, the signal lamp of electrical equipment.

2. the ornament lamp of various shapes can constitute the exquisite art work as the light transmissive material with different color.

3. lighting can satisfy at compound lamp under the situation of daylighting demand, the also available compound lamp of illuminator lamp.

4. explosion-proof aspect is as signal and illumination aspects such as mining, constructions.
