Description

Integrated LED lamp lens plate and LED lamp

Technical Field

The utility model discloses LED lamps and lanterns field, specific theory relates to integral type LED lamps and lanterns lens board and have the LED lamps and lanterns of this lens board.

Background

With the development of science and technology and the pursuit of people for good life, in urban night lighting, how to regulate and control the color temperature and the brightness of a lamp in real time according to the change of climate environment and the magnitude of traffic of people during traveling becomes a new direction of lighting development. If one LED lamp bead is assembled in the lens, light rays with different color temperatures cannot be subjected to refined light mixing; two beads are assembled on a common LED lens, emergent light in a range of 75-90 degrees along a road direction is still much, so that glare can be caused to vehicles or pedestrians at a distance, and the light interception requirement of road illumination cannot be met.

In order to solve the above problems, we have always sought an ideal technical solution.

SUMMERY OF THE UTILITY MODEL

The utility model aims at not enough to prior art to provide an integral type LED lamps and lanterns lens board.

In this specification, the length direction of the lens plate of the integrated LED lamp is left and right, the width direction of the lens plate of the integrated LED lamp is front and back, and the thickness direction of the lens plate of the integrated LED lamp is up and down, and these directions are defined only for convenience of description and do not limit the technical solution.

The utility model adopts the technical proposal that: integral type LED lamps and lanterns lens board has seted up a plurality of mounting hole along lens board border, the inboard of mounting hole is provided with two at least lens bodies, the lens body has a evagination curved surface and an indent curved surface, the evagination curved surface with the indent curved surface is the free curved surface, can effectually realize the secondary grading to the light source, obtains required illumination facula, improves energy utilization simultaneously and rates. The half-section type lamp is formed when the lens body and the two lamp beads are assembled, so that the maximum light intensity direction of light distribution of the two lamp beads is 0-75 degrees, and glare is less. Two lamp pearls can be assembled to the lens body, adopt different current control can reach the mixed light effect that becomes more meticulous. The integrated LED lamp lens plate can be manufactured by injection molding, is low in cost and efficiency and is suitable for mass production. Besides the function of light distribution, the integrated LED lamp lens plate also has the advantages of water resistance, dust resistance and direct exposure, so that the outermost glass lampshade can be omitted, and the additional Fresnel loss of the glass lampshade can be avoided.

As a further improvement of the technical scheme, the mounting holes are stepped holes, and bolts for fastening can be completely placed in the mounting holes, so that the lamp is attractive in appearance, and the bolts are dustproof, waterproof and rust-resistant.

As the further improvement of the technical scheme, in order to enhance the dustproof and waterproof effects, one side of the lens plate corresponding to the concave curved surface is provided with a circle of groove for placing a sealing ring, and the groove is positioned between the mounting hole and the lens body.

As a further improvement of the technical scheme, one side of the lens plate corresponding to the concave curved surface is also provided with two wire grooves, and the two wire grooves are respectively positioned at the left end and the right end of the lens plate. The two wire grooves are used for placing wires for connecting the two lamp beads respectively, the pattern is clear, and the maintenance is convenient.

An LED lamp comprising the integrated LED lamp lens plate is provided.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses a constitute half cut-off type lamps and lanterns when joining in marriage the dress with two lamp pearls, satisfy the demand of cut-off, can satisfy the demand of high, the low-temperature grading that becomes more meticulous simultaneously. Furthermore, the integrated LED lamp lens plate has the functions of light distribution, is waterproof and dustproof, and can be directly exposed outside, so that an outermost glass lampshade can be omitted, light loss is less, and cost is low. It has the advantages of fine light mixing, low cost and beautiful appearance.
