Abstract

The utility model discloses an LED energy saving lamp. Since LED bulbs are arranged on a planar plate in matrix, conventional LED lamp does not facilitate light scattering, and small in lighting angle and lighting scope. In order to overcome said problems, the utility model provides an LED energy saving lamp including a shield, LED bulbs, a holding plate, a PCB plate and a bottom cover, wherein the LED bulbs are fixed on the hemispherical holding plate, the power supply joints of the LED bulbs pass through the holding plate and connected with the PCB plate, and the lamp shield is detachably connected with the bottom cover. A concave lens, of which the external surface is convex, is arranged on the lamp shield. In such a structure, spherical holding plate enlarges light irradiating angle, and light exit angle is further enlarged through scattering by the concave lens with a convex external surface, thereby increasing lighting scope. The LED energy saving lamp is especially suitable for close-range lighting.

Description

A kind of LED electricity-saving lamp

Technical field

The utility model relates to a kind of LED electricity-saving lamp, particularly a kind of LED electricity-saving lamp that increases irradiating angle.

Background technology

At present, widely used street lamp divides according to illuminator has incandescent lamp, fluorescent lamp and high-pressure metal lamp etc.Wherein, incandescent lamp is to receive electro ultrafiltration to make wire luminous with filament, owing to be thermoluminescence, so most of electric energy changes heat energy into, can not produce light.So at the bottom of the luminous efficiency.Fluorescent lamp is to be that fluorescence gas in the airtight cloche receives electro photoluminescence through filament, forms plasma and luminous.High-pressure mercury lamp has the monomer luminous power, but it is big to take up space, and the light conversion ratio is lower, in luminous, also produces a large amount of heat.

The LED of a new generation has long, advantages such as light efficiency is high, radiationless, shock resistance and low-power consumption of life-span; Belong to energy-conservation environmental protection illumination; Therefore the LED lamp that with LED is light source also continues to bring out, but the LED of existing LED lamp the inside is arranged on the surface plate by matrix-style, is unfavorable for scattering of light like this; The angle of light is smaller, and range of exposures is limited.

The utility model content

It is good that the technical problem that the utility model will solve provides a kind of dispersion effect, and light angle is big, the LED lamp that range of exposures is wide.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

A kind of LED electricity-saving lamp comprises outer cover, LED bulb, supporting plate, pcb board and bottom, and the LED bulb is fixed on the hemispherical supporting plate; The power connection of LED bulb passes supporting plate and is connected with pcb board; Lampshade and bottom removably connect, and lampshade is provided with concavees lens, and the concavees lens outer surface is a convex surface.

Through above design, spherical supporting plate can enlarge the irradiating angle of light, is that the scattering of the concavees lens of convex surface is further amplified the beam projecting angle through outer surface again, enlarges the range of exposures of light, especially is fit to the irradiation of close shot.

Further, on the protruding sphere that is fixed on supporting plate of LED bulb equidistance.Emergent light is radiated on the object uniformly.

Further, the bottom wire hole goes out to establish a water joint, is provided with sealing gasket between lampshade and the bottom.Can reach the purpose of waterproof like this, prevent the generation of short circuit.

Further, bottom is provided with thermal window, is provided with ventilating fan in the thermal window, and the ventilating fan joint is connected with pcb board, and bottom and lampshade are that Heat Conduction Material is processed, and sealing gasket is that heat conductive silica gel is processed.Can the working environment of LED be maintained lower temperature like this, prolong the service life of LED.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model technical scheme is further specified:

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the exploded view of a kind of embodiment of the utility model.

The specific embodiment

As shown in Figure 2, a kind of LED electricity-saving lamp of the utility model comprises outer cover 5, LED bulb 2, supporting plate 3, pcb board 4 and bottom 7; LED bulb 2 is fixed on the hemispherical supporting plate 3, and the power connection of LED bulb 2 passes supporting plate 3 and is connected with pcb board 4, and lampshade 5 removably connects with bottom 7; Lampshade 5 is provided with concavees lens 1, and concavees lens 1 outer surface is a convex surface, on the protruding sphere that is fixed on supporting plate 3 of LED bulb 2 equidistance; Bottom 7 wire holes 11 go out to establish a water joint 9, are provided with sealing gasket 10 between lampshade 5 and the bottom 7, and bottom 7 is provided with thermal window 8; Be provided with ventilating fan 6 in the thermal window 8; The ventilating fan joint is connected with pcb board, and bottom 7 is processed for Heat Conduction Material with lampshade 5, and sealing gasket 10 is processed for heat conductive silica gel.

Install and the use step: at first, connector lug is passed supporting plate be connected, pcb board 4 is fixedly connected with lampshade 5 welding or other, concave mirror 1 is fixed on the top of lampshade 5 with pcb board 4 with LED bulb 2 equidistant being fixed on above the hemispherical supporting plate 3; Ventilating fan 6 is fixed on the bottom 7, and ventilating fan 6 joints are connected with pcb board 4, and pcb board 4 is connected with supply line, and lead passes entrance hole 11 and is connected with extraneous through water joint 9, and lampshade 5 and bottom 7 usefulness screws are fixed, and the centre is lined with hot silica gel sealing pad 10.This moment energized, LED bulb 2 is shinny owing to be fixed on the hemispherical supporting plate 4, light is emitting shape, when light ran into the outside face and is the concavees lens 1 of convex surface, light was further dispersed, the beam projecting angle is strengthened, the scope of illumination increases greatly.The heat that LED bulb 2 sends is discharged through thermal window 8 by the wind-force sucking-off that fan 6 blows out; Other waste heats are discharged into the external world through the good bottom 7 of heat conduction, sealing gasket 10 and outer cover 5; If run into the rainy day; Sealing gasket 10 can stop rainwater to be invaded with water joint 9, guarantees the normal illumination of light fixture.

For a person skilled in the art; Under the prerequisite that does not break away from the utility model structure; Can also make some distortion and improvement, should be regarded as the protection domain of the utility model like these yet, these can not influence effect and practical applicability that the utility model is implemented.
