Description

A kind of light

Technical field

The utility model relates to a kind of light, refers in particular to a kind of novel street lamp.

Background technology

Therefore the LED street lamp, uses the LED street lamp nervous for alleviating urban electric power because its voltage is low, electric current is little, little power consumption and long service life, practices thrift natural resources and has great importance.Yet when the LED street lamp was luminous, especially under the situation of fluorescent lifetime length, it produced great amount of heat, if can not in time dispel the heat, can cause the damage of LED street lamp.

In the prior art; The heat radiation of LED street lamp generally is that the heat radiation radiating fin is set on aluminium base; This heat radiation radiating fin is set to horizontal band, perhaps is horizontal perpendicular line, and the heat of the luminous generation of LED street lamp distributes heat through the mode of this heat radiation radiating fin with convection current.Yet the LED street lamp is mounted in the highway both sides, after automobile shuttles back and forth, must kick up a dust, and dust covers on the horizontal heat radiation radiating fin, plays the effect of resistance heat, thereby influences the effect of the heat radiation and the thermal convection current of LED street lamp.

Therefore, LED street lamp of the prior art has following defective: radiating effect is poor when in the highway complex environment, using, thereby service life is short.

In view of the above-mentioned defective of LED street lamp of the prior art, the inventor develops a kind of light that overcomes above-mentioned defective, and this case produces thus.

The utility model content

The purpose of the utility model is to provide a kind of light of good heat dissipation effect.

For reaching above-mentioned purpose, the solution of the utility model is:

A kind of light comprises body, aluminium base, lens pressing plate, lens and pressing plate; Embed safety glass in the pressing plate, pressing plate is installed in the body below; Aluminium base is installed between body and the pressing plate, and printed circuit is set on the aluminium base, connects a plurality of LED crystal grain in the printed circuit; The lens pressing plate is installed in the below of aluminium base, and corresponding LED crystal grain is provided with a plurality of mounting grooves on the lens pressing plate, and lens are installed in the mounting groove, and corresponding one by one with LED crystal grain; Wherein, Body comprises substrate and a plurality of radiating fin, and a plurality of louvres are set on the substrate, and radiating fin is crescent shape and is arranged on the substrate with the mode that tilts; Form the heat dissipation channel that is curved shape between radiating fin and the radiating fin, heat dissipation channel is communicated with louvre.

Further, the top of each heat dissipation channel is provided with pore.

Further, between pressing plate and body, be provided with sealing ring.

After adopting such scheme, the heat of the luminous generation of the utility model, heat radiating via hole gets into heat dissipation channel; Dispel the heat along heat dissipation channel; Be arranged on the substrate owing to radiating fin and with the mode that tilts, form the heat dissipation channel that is curved shape between radiating fin and the radiating fin, therefore; Dust can't cover on the heat dissipation channel, and it dispels the heat smooth and easy and good heat dissipation effect.Simultaneously, the heat dissipation channel design is curved shape, and the contact area of increase and air promotes radiating effect.

On the other hand, on the top of each heat dissipation channel pore is set, and heat dissipation channel is curved shape, according to bernoulli principle, the pressure that above pore, forms is less than the pressure of heat dissipation channel, thereby forms pressure difference, strengthens gas communication, further promotes radiating effect.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed explanation.

Consult Fig. 1 to shown in Figure 10, a kind of light that the utility model discloses comprises body 1, aluminium base 2, lens pressing plate 3, lens 4 and pressing plate 5.

Embed safety glass 6 in the pressing plate 5, pressing plate 5 is installed in body 1 below; Aluminium base 2 is installed between body 1 and the pressing plate 5, and the printed circuit (not shown) is set on the aluminium base 2, connects a plurality of LED crystal grain 21 in the printed circuit.The connected mode of a plurality of LED crystal grain 21 is preferably and is connected in parallel.

Lens pressing plate 3 is installed in the below of aluminium base 2; And electric elements on the aluminium base 2 and circuit (not shown) are covered; Corresponding LED crystal grain 21 is provided with a plurality of mounting grooves 31 on the lens pressing plate 3, and lens 4 are installed in the mounting groove 31, and corresponding one by one with LED crystal grain.The effect of lens 4 is to change the field of illumination.

Wherein, Body 1 comprises substrate 11 and a plurality of radiating fin 12, and a plurality of louvres 13 are set on the substrate 11, and radiating fin 12 is crescent shape and is arranged on the substrate 11 with the mode that tilts; Form the heat dissipation channel 14 that is curved shape between the radiating fin 11, heat dissipation channel 14 is communicated with louvre 13.
