Description

Escalator or moving sidewalk LED handrail wainscot illumination equipment

Technical field

The present invention relates to a kind of escalator or moving sidewalk LED handrail wainscot illumination equipment.

Technical background

Moving sidewalk and escalator carry big flow personnel extensively to be applied to large-scale public places such as market, public place of entertainment, adrm, subway because of it has efficiently.For the safety that guarantees to transport, the both sides of escalator and moving sidewalk all are provided with handrail wainscot (being commonly called as breast board, guardrail), apron plate, handrail etc. and carry out fender guard; Basic and the step of handrail is same moved further.For keeping the attractive in appearance and safety of single-piece, the handrail wainscot is made of case hardened glass usually.At present more existing high-grade escalators and moving sidewalk are equipped with illuminating lamp, as installing the general lighting light source additional on the wainscot next door, perhaps adopt bar shaped illumination (light transmitting fiber).As the patent No. 95193327; 96197798; 200410059267.4, but the technology that these patents provided is different with the present invention, and generally can only play a role in lighting, lack aesthetic feeling.Take the ordinary light source illumination, the wavelength of light source is not single, and excitation is poor, poor visual effect, and the light source of general filamentray structure, and poor stability, service life is short, and the waste electric energy.In a word, none device technique provided by the present invention of prior art.

Summary of the invention

Purpose of the present invention is at the prior art weak point, and the handrail wainscot illumination equipment of a kind of novel attractive in appearance, reliable, economize on electricity, environmental protection is provided.The present invention proposes to adopt LED (light-emitting diode light emitting diode) as new type light source, and the light of LED is coupled into the glass wainscot by an end face of glass, and the glass position that light is handled through frosted scatters out, and realizes that illumination beautifies purpose.LED mainly contains as the advantage of lighting source: 1, wavelength is single, excitation is high, good visual effect, super bright; 2, send cold light, heat little, can not damage lamp socket, safety is good; 3, energy consumption is low, light output is high, environmental protection; 4, long service life generally can reach 100,000 hours, is common bulb 5-10 times; 5, it is fast to light speed of response, less than 1us, does not have any build-up of luminance process.

The concrete technical scheme of the present invention is: a kind of escalator or moving sidewalk LED handrail wainscot illumination equipment is characterized in that: it comprises that LED (light-emitting diode light emitting diode) linear array pipe [1], glass wainscot [2], guide rail [3] and power supply [10] constitute; Wherein the light that sends of LED linear array pipe [1] is coupled into the glass wainscot by an end face of glass wainscot [2]; LED linear array pipe [1] fixes in the cavity that forms between the top of glass wainscot [2] and guide rail [3]; The light that is coupled into the glass wainscot passing through of glass surface the frosted position of handling scatter out, realize that illumination beautifies purpose.This is because light utilizes the total reflection principle of light can not leak at bright and clean glass surface, and will scattering take place and penetrate from hair side in the frosted glass surface light of polishing.Above-mentioned escalator or moving sidewalk LED handrail wainscot illumination equipment, wherein LED linear array pipe [1] is made up of plurality of LEDs device [4], substrate [5], shell [6], packed layer [7], reflecting horizon [8]; Each LED device [4] is linear rank and keeps a determining deviation (as about 10mm) to be fixed on the substrate [5], and packed layer [7] plays the effect of protection LED device, and also scribbles reflecting horizon [8] on it, to increase the degree of utilization of LED light.LED device [4] is formed led array pipe [1] with in parallel and series connected form, and array pipe [1] arrives power supply [10] by cable connection.Adorn a shell [6] and packed layer [7] around substrate [5], purpose is for increasing mechanical strength.

Above-mentioned glass wainscot process special processing: LED is optically coupled into end face and does polishing; After the glass polishing both surfaces, adopt the technology of frosted glass to polish the pattern that needs demonstration at the select location place, even pattern part forms the frosted glass with certain granules thickness, remainder keeps degree of finish.

The specific embodiment

Below, further describe the principle of work of the present invention and the specific embodiment in conjunction with the accompanying drawings.

With reference to shown in Figure 1, the light that LED sends is coupled into glass through an end face of glass wainscot [2], because glass is optically denser medium, air is an optically thinner medium, total reflection principle according to light, total internal reflection all can take place at two inside faces of glass in light, so light will transmit in glass, is similar to a fiber waveguide.If but glass surface has part to be polished into frosted glass or figuratum frosted glass, also can polish becomes a frosted glass broadband, because the frosted glass surface is equivalent to exist microgranular texture, and particulate has scattering process to light, therefore light will be mapped to the glass outside through the surface of frosted glass, play illuminating effect.People see is light-emitting zone with same shape of frosted glass and pattern, it with do not have luminous bright and clean glass surface to form strong striking contrast on every side.In addition,, improve the brightness of pattern, can be designed to identical pattern at two surperficial correspondence positions of glass in order to increase scattered intensity.

With reference to Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the structure of the linear led array pipe [1] in escalator or the moving sidewalk LED handrail wainscot illumination equipment as shown in Figure 4, linear led array pipe [1] is stuck between glass wainscot [2] and the guide rail [3], form a cavity structure between guide rail [3] and the glass wainscot [2], led array pipe [1] just in time is stuck in the cavity, cavity has a certain size and shape according to the thickness of glass wainscot, and formed cavity can be rectangle between the top of glass wainscot [2] and the guide rail [3], square, semicircle, oval or fan-shaped cavity; Wide 8mm～the 20mm of cavity, high 10mm～20mm, its size will determine according to actual position.LED arranges spacing can be at 5mm～100mm, and the length of being arranged should decide according to the length overall of handrail wainscot.
