The LED module body comprises a circuit board and a plurality of LED lamp beads which are distributed on the circuit board. The LED module body is fixed on the substrate, the light transmission cover is located above the LED module body and comprises lenses at the edge and lenses in the middle, the edge of the light transmission cover is sleeved with the side frame, the light transmission cover is pressed downwards by the side frame to be connected and fixed with the substrate, the driving power source is arranged on the back face of the substrate and is electrically connected with the LED module body, the radiating fins are evenly distributed on the back face of the substrate, and each radiating fin is provided with a plurality of ventilation grooves of which the height is equal to that of the radiating fins. The LED module is simple in structure and practical, and has the good radiating effect.

Description

The LED module

Technical field

The utility model relates to a kind of LED module, and the LED module that especially a kind of thermal diffusivity is good, simple and practical belongs to the LED equipment technical field.

Background technology

LED is the abbreviation of light emitting diode, is a kind of solid luminescence material that can convert electrical energy into luminous energy.Because the advantage of its energy-conserving and environment-protective has the trend that replaces gradually conventional light source at present.Because the LED wafer can produce heat in luminescence process, the rising of chip temperature can strengthen non-radiative compoundly, has further slackened luminous efficiency.

The modes of the at present most employing of great power LED heatsink transverse, by the fin of LED base the dissipation of heat that PN junction produces to be gone out, because high-power LED chip adopts stack to pile up and places, so the heat that PN junction produces is concentrated by fin and is distributed, because heat flow rate per unit area is limited, so also be easy to cause heat build-up, the PN junction increase in temperature causes the bad phenomenon such as LED light decay.

The utility model content

The utility model namely is the poor radiation that exists for present led chip, easily causes the problem of heat build-up, provides a kind of simple and practical, and has the LED module of great heat radiation effect.

Specifically, LED module described in the utility model, comprise substrate, led module, frame, diffuser, driving power and radiating fin, wherein, led module comprises circuit board and the plurality of LEDs lamp pearl that is arranged on the circuit board, led module is fixed on the substrate, diffuser is positioned at the led module top, the lens that comprise edge and middle part, frame is enclosed within the edge of diffuser and diffuser is pressed down with substrate and is connected and fixed, driving power is arranged on substrate back and is electrically connected with led module, and the back side of substrate also is provided with a plurality of equally distributed radiating fins, and all has a plurality of ventilation slots contour with radiating fin on each radiating fin.

Further, described led module also comprises lens and the lens carrier that is arranged on the LED lamp pearl.

Further, described frame is that bolt is connected or clamping with substrate.

Further, also be provided with sealing ring between the edge of described diffuser and the substrate.

LED module described in the utility model, simple and practical, have good radiating effect, and the air that is arranged so that of ventilation slot circulates better on the radiating fin, the setting of lens and lens carrier is again so that described LED module has better lighting effect on the LED lamp pearl.
