Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
The utility model provides a first embodiment is: an LED street lamp with peripheral side lighting function mainly comprises a light source mechanism 1, a flat glass 2, an LED light source 4 and a connecting mechanism, as shown in fig. 2(a) and (b).
Wherein, light source mechanism 1 contains a recessed light source chamber, and LED light source 4 is installed and is fixed on light source chamber bottom surface. The plate glass 2 is a flat tempered glass plate with a certain thickness and side surfaces at the periphery, and is arranged on the light source mechanism 1 through a connecting mechanism.
The connecting mechanism comprises through holes distributed on the peripheral edge of the plate glass, threaded holes opposite to the through holes and distributed on the peripheral edge of the light source mechanism 1 and screws 3, and the screws 3 penetrate through the through holes on the plate glass 2 to be connected to the threaded holes on the light source mechanism 1, so that the plate glass 2 can be fixed.
After the connection in this way, the four side surfaces of the plate glass 1 are completely exposed in the air without any optical shielding, so when the LED light source emits light, the light firstly enters the plate glass, most of the light escapes from the front surface of the plate glass and irradiates the road surface, and front light is formed; and a small part of light will escape from the side surface of the peripheral glass exposed in the air, and light emission from the peripheral side surface is formed, as shown in fig. 2(b) and (c).
In the embodiment, the peripheral side light emitting function of the LED street lamp ensures that the light emitting angles of the LED light source along the width, namely the road direction and/or along the length direction of the LED light source are both larger than 180 degrees (even larger than 225 degrees), and the national standard of road inductivity of lighting facilities is met; but also avoids the loss of the partial luminous flux and improves the luminous efficiency of the whole lamp. In addition, the light emitting angle of the LED street lamp is larger than 180 degrees (even larger than 225 degrees), so that the urban landscape lighting effect of the LED street lamp is improved.
It is noted that in this embodiment, the screw 3 may be formed by chemical adhesive, i.e. the connection mechanism may be constituted by adhesive, a threaded hole and a through hole. And (3) pouring the bonding glue into the through hole on the plate glass 2 and the threaded hole on the light source mechanism 1 and curing to form a screw 3, so as to fix the plate glass 2. If the adhesive is transparent after being cured, light rays originally blocked and absorbed by opaque metal screws and the like can escape from the flat glass without being blocked, and the lighting effect and the illumination effect of the lamp can be greatly improved.
Since the plate glass 2 is fixed above the light source mechanism 1 in a protruding manner, the front and the side surfaces are not shielded by any optical shielding, so that the whole plate glass of the LED street lamp emits light. The light emitted by the LED light source can penetrate through the front surface and the peripheral side surface of the plate glass and the transparent connecting mechanism to emit light outwards, and almost no optical shielding and absorption exist. The LED street lamp not only can greatly enlarge the light-emitting angle of the LED street lamp, meet the road inductive national standard of lighting facilities and improve the lighting effect of the lamp, but also can greatly improve the lighting effect of urban landscapes. The lighting effect of the lamp and the road lighting effect can be obviously improved.
The utility model provides a second embodiment is: LED street lamp with two side light emitting functions. The main structure of the LED street lamp of the present embodiment is similar to that of the present embodiment, and is also composed of a light source mechanism 1, an LED light source 4, a plate glass 2, and a connecting mechanism. Except that the connection mechanism in this embodiment is composed of a press frame 3, screws 5 and threaded holes, the press frame 3 is pressed on both side surfaces and end surfaces of the plate glass 2 in the length direction and is connected to the threaded holes of the light source mechanism 1 by the screws 5, thereby achieving fixing of the plate glass 2, as shown in fig. 3 (c).
The other two sides of the sheet glass 2 in the width direction are not covered with the press frame and are exposed to the air without any optical shielding, as shown in fig. 3(a), (b). When the LED light source 4 emits light, the light firstly enters the plate glass 2, most of the light escapes from the front surface of the plate glass 2 and irradiates the road surface to form front light; a small portion of the light will escape from the two glass sides exposed to air, creating side light. The two side faces of the LED street lamp emit light, so that the light emitting angle of a light source along the road direction is ensured to exceed 180 degrees (even 225 degrees), and the national standard of road inductivity of lighting facilities is met; but also avoids the loss of the partial luminous flux and improves the luminous efficiency of the whole lamp; in addition, the lighting angle of the LED street lamp is larger than 180 degrees (even more than 225 degrees), so that the urban landscape lighting effect of the LED street lamp is improved.
The utility model provides a third embodiment is: the present embodiment is a further improvement on the basis of the third embodiment. As shown in fig. 4(a), the LED street lamp of the present embodiment is also composed of a light source mechanism 1, an LED light source 4, a plate glass 2, and a connecting mechanism. As shown in fig. 4(b) and (c), the connection mechanism not only fixes the plate glass 2 at the front and rear ends of the plate glass 2 by the pressing frames 3, but also fixes and reinforces the plate glass 2 at the middle and side positions of the plate glass 2 by the connection mechanism as in the first embodiment, so as to prevent the problem that the plate glass 2 deforms too much due to overlong size and the waterproof sealing performance between the plate glass 2 and the light source mechanism 1 is deteriorated. Two side surfaces of the plate glass 2 distributed along the road direction are completely exposed in the air and have no optical shielding, so when the LED light source emits light, partial light entering the plate glass can be emitted through the two glass side surfaces, and the side surface light emitting function of the LED street lamp is further formed.
