Abstract

The utility model provides a Light-Emitting Diode (LED) railing lamp, which comprises an LED lamp bead, a lens, a substrate and a radiator, wherein the LED lamp bead is arranged on the substrate; the radiator has an annular side surface and two end surfaces; a spring piece is fixed on the annular side surface of the radiator; one end surface of the radiator and the cross section of the radiator form a slant included angle; the substrate is fixed on the slant end surface; an installation hole is formed on the other end surface of the radiator; a compression spring is arranged in the installation hole; and one end of the compression spring extends out of the installation hole. The LED lamp bead is arranged on the slant end surface of the radiator through the substrate; the LED lamp bead has the light distribution property of a deviation angle and can acquire more lights, therefore, the LED lamp bead is good for pedestrians to see roads; the spring piece tensions the hole for mounting a railing; the compression spring is put against the bottom of the railing and inter-acts with the tensioning force of the spring piece, so as to be fixed on the railing; as the compression spring is telescopic, the LED railing lamp can be conveniently mounted on railings different in specifications of inside diameters, as a result, adaptability and mounting convenience of the LED railing lamp are reinforced.

Description

LED railing lamp

Technical field

The utility model relates to the lamp that is installed on the railing, relates in particular to a kind of LED railing lamp.

Background technology

In order to improve visuality and sight, LED is applied to signal and sign illumination, the traffic lights on the road more and more; Building; Induced light in the street with sketch the contours the vertical lighting of profile, the multicoloured illumination of flower garden light in city square, gardens, walking street all is to produce after adopting the LED of super brightness; Characteristics of energy saving that it is excellent and extremely long service life, more and more receive the attention of each urban planning designing unit.In urban landscape construction, the LED lamp is being brought into play own irreplaceable effect.The installation time and effort consuming of existing built-in railing lamp, and the internal diameter specification of railing is different, and maintenance is extremely inconvenient with maintenance; Luminous intensity distribution does not adopt human oriented design simultaneously; For the ladder step, reach the passageway and do not adopt the distribution of light of Duoing than the outside, the radiation response of light is relatively poor.

The utility model content

The technical problem that the utility model solves is: provide a kind of easy for installation, and can improve the LED railing lamp of radiation response.

The technical scheme of the utility model is: a kind of LED railing lamp, comprise LED lamp pearl and lens, and it is characterized in that; Also comprise substrate and radiator, said LED lamp pearl is arranged on the substrate, and said radiator has ring side and two end faces; The ring side of radiator is fixed with spring leaf, has slanted angle α between the end face of radiator and the cross section of radiator, and this end face constitutes the inclined end face of radiator; Said substrate is fixed on the said inclined end face; Another end face of radiator is provided with an axial installing hole, is provided with the compression spring in this installing hole, and an end of compression spring extends said installing hole.

There are four spring leafs the ring side of said radiator through bolt.

Said lens are installed on the inclined end face of said radiator.

Said lens are fixed on the lens mount, and this lens mount is provided with pin, and the inclined end face of said radiator is provided with the pin-and-hole that matches with said pin.

Said lens material is translucent frosted PC.

The bead weld of said LED lamp is connected on the said substrate.

Said substrate and said radiator all adopt metallic aluminium to process, and are adhesively fixed through heat-conducting glue between the inclined end face of substrate and radiator.

The value of said slanted angle α is 10 °≤α≤20 °.

Be adhesively fixed between the inserting end of said compression spring and the bottom of said installing hole.

The beneficial effect of the utility model is: pearl is arranged on the substrate LED lamp; Substrate is fixed on the inclined end face of radiator; Therefore LED lamp pearl has had the luminous intensity distribution character of drift angle, and the utility model is installed in the passageway, ladder will obtain more rays during the step, is beneficial to the pedestrian and looks the road; The position, hole of railing is installed in the spring leaf tensioning; The compression spring withstands the railing bottom, produces deformation elastic force, interacts with the spring leaf tensile force; With the fixing upper-lower position of the utility model on railing; Because the compression spring is scalable, so the utility model can be installed on the different railing of internal diameter specification easily, has improved the suitability of the utility model and the convenience of installation.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Referring to Fig. 1～Fig. 5, a kind of LED railing lamp comprises LED lamp pearl 1, lens 2, substrate 3 and radiator 4; 1 welding of LED lamp pearl is arranged on the substrate 3, and the advantage that LED lamp pearl 1 has solid light source is: do not inflate no glass shell; No air seal problem, shock-resistant, the response time fast (the microsecond order of magnitude); Frequently light on and off repeatedly, long service life, the replacement cycle is long.Radiator 4 has ring side and two end faces, and the ring side of radiator has 5, four spring leafs 5 of four spring leafs to be used for the position, hole that tensioning is installed in railing through bolt, thus the peripheral direction position of fixed L ED railing lamp on railing.Have slanted angle α between the top end of radiator 4 and the cross section of radiator, this end face constitutes the inclined end face 41 of radiator, and in the present embodiment, slanted angle α=15 ° can also be 10 ° or 20 °.Substrate 3 is fixed on the inclined end face, and wherein, substrate 3 all adopts metallic aluminium to process with radiator 4, is adhesively fixed through heat-conducting glue between the inclined end face 41 of substrate 3 and radiator.The bottom end face of radiator 4 is provided with four legs that extend axially out 8 and an axial installing hole; Be provided with compression spring 6 in this installing hole; One end of compression spring 6 extends the installing hole of radiator 4, is adhesively fixed between the installing hole bottom of the inserting end of compression spring 6 and radiator 4, and compression spring 6 is used to withstand the railing bottom; Produce deformation elastic force, and with the above-below direction position of four spring leafs, 5 tensile force interaction fixed lamp body.Deflection is avoided taking place in location when four legs 8 of radiator 4 bottoms are used for the railing lamp and are pressed into railing.The material of lens 2 is that (PC is the abbreviation of Merlon to translucent frosted PC; The English of Merlon is Polycarbonate, is called for short the PC engineering plastics, and the PC material is exactly a kind of in our the said engineering plastics in fact; As by widely used material in the world wide); The light of LED lamp pearl penetrates from translucent frosted PC lens, and bright dipping is evenly soft, avoids dazzle.Lens 2 are installed on the inclined end face 41 ' of radiator; Wherein, Lens 2 are fixed on the lens mount 7; This lens mount 7 is provided with two pins 7 ', and substrate 3 is provided with and is used for the via hole 3 ' that two pins 7 ' pass, and the inclined end face 41 of radiator is provided with two pin-and-holes 41 ' that match with two pins 7 '.
