Abstract

The utility model relates to a novel indicating lamp which is used for displaying the operating condition and the operational aspect of distribution equipment and control systems. The utility model uses a capacitor as an amperite, uses a superhigh brightness LED as a light source, and is matched with a light-guiding conical column with a special shape to enlarge luminous surface, so the utility model has unprecedented obvious advantages. The light-guiding conical column is made of transparent insulating material; the light-guiding conical column can both be solid or hollow as required.

Description

A kind of distribution board long-life energy-saving indicator light

The invention belongs to the HO2 technical field of H portion among the IPC, is electric power system distribution auxiliary equipment, particularly a kind of novel indicator light that is used to show power distribution equipment and control system operating state and ruuning situation.

In order to make power system dispatching, on duty, administrative staff a understanding directly perceived, instant, open-and-shut and judgement be arranged to operating state, the ruuning situation of power distribution equipment, control system, many indicator lights need be set, existing technology has:

(1) with wattage transformer miniature incandescent lamp is powered, individual components of common composition such as small transformers, bulb and housing, this is a kind of conventional method.This mode power consumption is many, caloric value is big, bulb life is short, fragile (particularly fixedly the rib collar of bulb), transformer are a perceptual device, and is unfavorable to improving power factor.

(2) neon tube is energy-saving, and this is a kind of newer product.This mode is with a resistance step-down current limliting, and neon tube is a luminous element.Though energy consumption, heating decrease, do not eliminate short, flimsy shortcoming of life-span yet.

The utility model is in order to overcome above-mentioned each the deficiencies in the prior art, energy consumption is many, the life-span short, drawback such as fragile is got rid of, and uses the electric capacity ballast instead, superhigh brightness LED is done light source, the photoconduction awl post that is equipped with special shape amplifies light-emitting area, makes it have unprecedented obvious advantage.

One of emphasis of the present utility model is a photoconduction awl post, and it is made with transparent insulation material, as required, can be real core, also hollow.Its two of externally connecting together the end of by the end of as on the form removes most advanced and sophisticated bullets, for ease of explanation, it is divided into body 7 (Fig. 2) behind awl post precursor 5, the awl post, is positioned at the root place of cone in two sides of awl post precursor 5, respectively remove two planes 6 that a part forms symmetry; Body 7 has a cylindrical tip 8 behind the awl post, and a hole 9 (Fig. 3) that reaches deeply in the awl post is arranged in the top 8, and light-emitting diode is solid in hole 9 with regard to glue.On the conical outer surface of body 7 behind the awl post, one deck minute surface is set, reflect back and concentrate in order to the light that will scatter and bore post precursor 5.

Procapsid 2 of the present utility model as shown in Figure 5, there is mother's precession sieve rib-loop the outside, the interior forward end opening part, monosymmetric respectively have an outstanding plane 11 (Fig. 6, Fig. 7).Procapsid 2 and the housing 4 common shells (Fig. 1) that constitute the long-life energy-saving indicator light.Housing 4 is similar to existing indicator light housing.

There is hole, a garden 10 (Fig. 8) in the central authorities that are provided with on one side the element board 3 of breach, and the cylindrical tip 8 of body 7 behind the awl post just in time can be injected in this hole.

On the element board 3 electronic component is installed, circuit as shown in Figure 9.Capacitor C ₁With resistance R ₁After the parallel connection, a termination power, another terminating diode D ₁Negative pole and diode D ₂Positive pole.Electrochemical capacitor C ₂, resistance R ₂, light-emitting diode D ₃After three's parallel connection, its negative pole terminating diode D ₁Anodal; Anodal terminating diode D ₂Negative pole, connect the other end of power supply then jointly.

By above improvement, make and the utlity model has tangible advantage: the light-emitting diode power consumptive province, have only one 1/tens even several percent of bulb, the life-span is long, can reach more than 100,000 hours even 1,000,000 hours, more much longer than 500 hour rated life time of bulb; Compare with small transformers, in light weight in order to the capacitor of ballast consumed energy (like this in theory) not, and can improve power factor; Fixedly the rib collar used of bulb is expelled, thereby does not have the anxiety of damage forever after being equipped with photoconduction awl post!

Execution mode:

Photoconduction awl post is injection molded with transparent insulation materials such as polystyrene or polymethyl methacrylate, can be real core, and also hollow is decided as required.Reflection ray minute surface behind its awl post on the body 7, its method to set up have more known technology available: the surface sensitization is handled back nickel plating, utilizes the silver mirror reaction preparation or is pasted aluminium foil after will boring post ...

As shown in Figure 1, photoconduction is bored post 1 to be placed in the procapsid 2, make the awl post precursor 5 of photoconduction awl post stretch out at enclosure interior front opening place in the past, and awl post precursor root two side planes 6 (seeing Fig. 2, Fig. 3, Fig. 4) are meshed with the outstanding plane 11 (seeing Fig. 6, Fig. 7) of symmetry of both sides, procapsid front opening place, make photoconduction awl post in procapsid, can not rotate about, can not deviate from from front end.After the protrusion counterpart engagement of the breach of element board 3 and procapsid 2, be clamped between procapsid 2 and the housing 4.In hole, central garden 10 (see figure 8)s of element board 3 ... cylindrical tip 8 (see figure 2)s of body 7 behind the reeve awl post.Like this, the outstanding plane 11 at cylindrical tip 8, the procapsid front opening place of body, awl post precursor root plane 6 behind the hole, garden 10 of element board, the awl post, their coefficient results make photoconduction awl post stable, firm performance usefulness on the position at its place.

In Fig. 9 circuit, capacitor C ₁Be ballast capacitor, it removes and is added in light-emitting diode D ₃On unnecessary voltage, and the electric current that flows through of restriction is a suitable value.Resistance R ₁Be bleeder resistance, its effect is to bleed off capacitor C when having a power failure ₁The electric charge of last storage.When the binding post (two of Fig. 9 end points just) of novel indicator light, during the incoming transport circuit, diode D ₁Carry out halfwave rectifier and take the negative half period of alternating current, D ₂Allow the positive half cycle that does not utilize form path (if will utilize positive half cycle reconfiguration to become full-wave rectification again, facts have proved no obvious advantage, in rain elements that increase) more.Electrochemical capacitor C ₂With diode D ₁Negative half period filtering after the rectification becomes than galvanic current and supplies with light-emitting diode D ₃Make the energy, C ₂Important role, it has very strong buffer capacity, can prevent extremely effectively that impulse overvoltage and surge current are to light-emitting diode D ₃Injury.Resistance R ₂Shield, prevent to work as D ₃C during open circuit ₂By too high voltage breakdown.Glue is fixed in the light-emitting diode D in the body opening 9 behind the awl post ₃Available two series connection so more can increase brightness.
