Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1-4 schematically illustrate an integrated guardrail light projector of the present invention. As shown in fig. 1, the integrated guardrail flood light of the invention comprises a housing, a light source and a circuit for supplying power to the light source. Wherein the housing is substantially U-shaped and is assembled from a square middle part 2 and two side end parts 1, the end parts 1 are formed by die casting, the middle part 2 is made of extruded aluminum, thereby the middle part 2 of the housing with corresponding length can be cut according to the actual length of the guardrail post. The end portion 1 comprises a square main body 11 butted with the middle portion 2 and a mounting plate 12 extending out of the main body 11, wherein a threaded hole 13 is formed in the mounting plate 12, and the threaded hole 13 is matched with the screw 8 so as to fixedly mount the projection lamp on two sides of the guardrail column. The threaded holes 13 are matched with the screws 8, so that the mounting positions of the projection lamps on two sides can be adjusted more accurately, and the positions of the projection lamps on two sides can be adjusted conveniently, so that a better guardrail plate lighting effect is obtained. The projection lamp provided by the invention has a simple and elegant appearance, the outer surface of the projection lamp is basically a plane, the compatibility with the appearance of the square column is good, and the projection lamp is convenient to clean sundries around the projection lamp in the use process.

Referring again to fig. 1, in this embodiment, the top surface of the middle portion 2 includes four light-transmissive holes 21. It is contemplated that a corresponding number of light-transmissive holes 21 may be provided in the top surface of the intermediate portion 2, depending on the actual application. The light-transmitting holes 21 are closed by a transparent cover 23, and the outer surface of the transparent cover 23 is flush with the outer surface of the middle part 21, so that dust, dirt and the like are prevented from entering the light-transmitting holes 21, and the self-cleaning function is achieved. The inner side of the transparent cover 23 is provided with the grille 22, one side of the grille 22 close to the guardrail posts is sparse, and one side of the grille 22 far away from the guardrail posts is dense, so that light emitted by the lamp is basically used for illuminating the guardrail posts, the upward-thrust glare is small, and adverse effects on tourists close to the guardrail are avoided.

Fig. 2 is a side view of the integrated guardrail flood light. As shown, in the case of a balustrade panel which needs to be illuminated, the side of the end portion 1 may also be provided with a light-transmissive aperture 14, similar to the light-transmissive aperture 21 of the intermediate portion 2, the light-transmissive aperture 14 of the end portion 1 being closed by a transparent cover. In order to project light onto the balustrade panel, a polarizing lens 9 is provided at the end, which in this embodiment deflects the light emitted by the light source by 20 ° towards the balustrade panel, thereby illuminating the balustrade panel more effectively. The inner side of the light-transmitting holes 14 can be provided with a grid, and in order to reduce glare caused by light emitted from the end light-transmitting holes 14 to a side direct-view lamp, the end light-transmitting holes 14 are made of an off-angle grid. Preferably, the inclination angle of the grating is 5-8 degrees. The inclination angle is too small, the anti-glare effect is not ideal, the inclination angle is too large, and the illumination area is too small. The invention uses the deflection angle grating and the polarized lens in a matching way, can realize the anti-dazzle in the transverse direction and the longitudinal direction, while the common grating can only realize the anti-dazzle in one angle.

Fig. 3 shows a cross-sectional view of the integrated guardrail flood light. As shown in the figure, the lighting module is arranged at the position corresponding to each light hole in the interior of the lighting module. For example, the end lighting modules 3 corresponding to the end light transmission holes 14 include two sets of illumination lamps, and the number of illumination lamps of the middle lighting module 4 corresponding to the light transmission holes 21 of the middle portion 2 is determined according to the width of the square column and the need. The middle lighting module 4 is arranged on a support part of the shell through a sliding block 5, the shell also comprises a constant current source 6 and an outer inserting shell plate 7, the internal circuit is a series circuit, the working voltage is DC24V, and the middle lighting module is driven by constant current.

Fig. 4 shows a bottom view of the integrated guardrail projector, the bottom surface of which can be provided with an opening, and the electric wire passes through the opening to be connected with an external power supply circuit. Therefore, the electric wire can be hidden at the bottom of the lamp, so that the lamp is more attractive in use.

When the integrated guardrail projection lamp is used, the left and right end illuminating modules 3 and the left and right end parts 1 of the shell are respectively assembled, the middle illuminating module 4 and the middle part 2 of the shell are assembled, the left and right end parts 1 and the middle part 2 are assembled together through the cross countersunk head screws, and leads of all modules are connected in series and connected with the constant current source 6 to form the integrated guardrail projection lamp. When the guardrail projection lamp is used, the integral guardrail projection lamp is arranged at the root part of the guardrail column, the guardrail column is positioned between the two mounting plates 12, and the position is adjusted and fixed by the screw 8.

Fig. 5 schematically illustrates a state view of the use of the integrated guardrail floodlight of the present invention, which shows three sets of modular lamps having different projection manners. The projection lamp with light sources on three sides can be installed on the guardrail columns in the middle, and the projection lamp with light sources on two sides can be used by the guardrail columns at two ends as required. The light of the integrated guardrail projection lamp can project light in three directions, so that the stone guardrail plate and the stone column are illuminated. Proved in the in-service use, the integral type guardrail projecting lamp of this embodiment's illuminating effect is good, and the sky light pollution is minimum, and the installation is succinct convenient and more can integrate into the building.
